Floor 11 — The Abyss Threshold

February 9, 2012 - 11:42 AM

(Kaiser Everhart)

The dust finally settled, coating my uniform in a thick layer of grey ash.

We were sitting in complete darkness, save for the faint, bioluminescent moss glowing weakly on the cavern walls. Scarlet was lying in my arms, her breathing shallow and ragged. The purple discoloration had already spread past her elbow, webbing through her pale elven skin like cracked glass.

Axel was pacing back and forth, coughing violently and kicking rocks.

"What the hell was that?!" Axel demanded, his voice cracking with panic. "The ceiling just fell! The entire floor caved in! Tell me what’s going on, useless!"

I ignored him, keeping my eyes fixed on Scarlet’s arm.

Scarlet is infected with an aggressively growing poison.

Why is a biological poison acting with the absolute certainty of a magical curse? Magic doesn’t have biology. Biology has rules.

If it spreads through the bloodstream and paralyzes the nervous system, it’s a biological agent—likely a protein-based necrotic virus or a prion. Proteins are nothing more than fragile structural chains held together by chemical bonds. If this is a protein chain, then it has a structural weakness.

It can be denatured. Thermal denaturation is out—heating a prion requires 600 degrees Celsius, which would cook her alive. But chemical denaturation? If I can find a strong reducing agent—sulfur compounds from a volcanic vent or concentrated mineral acids from the deeper cavern floors—I can break the bonds and halt the replication without using a single drop of "godly" healing magic.

I need resources. Fast.

"Hey! Are you deaf?!" Axel marched over, towering over me. "What do we do?!"

I looked up at him, my expression perfectly flat.

"We are on Floor 11." I said, pulling the Lumina from my pocket. The screen was dead black. "Our tracker doesn’t work down here. The range is completely severed." I pointed back up the stairs, where thousands of tons of enchanted rock sealed the entrance. "And looking at that, rescue won’t be coming anytime soon."

Axel stared at the rubble. The color drained from his face.

"Floor 11..." Axel muttered, stepping back. He looked absolutely horrified. "Floors 11 to 20... the mechanics change. Rule 8 of Dungeon Delving: ’The monster is never the real threat. The dungeon is the boss.’ And Rule 1: ’The ceiling is the enemy.’ We have no marked paths. We have no map. We are completely finished. We’re going to die down here..."

"Then we explore." I said calmly, adjusting Scarlet’s weight in my arms. "We reach Floor 20. We might find a functioning emergency portal there."

Axel’s eyes widened in disbelief, then narrowed into a vicious glare.

"Are you going against my orders?" Axel snarled, stepping closer, his axe sparking weakly. "I am the strongest. I lead. And I am not burdening myself with a dying girl and a useless, magic-less extra. We stay here and wait."

I looked at him. "You were the one who batted that parasite directly toward her." I stated, my tone devoid of emotion. "You’ve been griefing your own teammates since Floor 1."

Axel snapped. He grabbed me by the collar of my uniform, hauling me half an inch off the ground.

"Shut your mouth!" Axel threatened, his breath smelling like stale ozone. "If you want to live, you follow my orders! You carry the bags. You carry the dead weight. I’ll see if I can heal her."

He dropped me and raised his hand toward Scarlet’s purple arm, gathering a faint surge of restorative lightning magic in his palm—a crude, muscle-stimulating healing technique.

"Stop." I said, catching his wrist.

My grip was iron-tight. Axel tried to pull his arm back, but he couldn’t move an inch.

If he uses magic on her right now, I reasoned internally, he will kill her.

Healing magic works by stimulating rapid cellular division and increasing blood flow to repair tissue. But this poison is a virus. It uses cellular division to replicate. If Axel accelerates her metabolism with healing magic, the poison will exponentially spread, reaching her heart in minutes instead of hours. I needed her metabolism to remain as slow as possible.

I needed her to get more poisoned, naturally, to buy time for a chemical cure.

But I couldn’t tell Axel that. He wouldn’t understand a single word of the biochemistry.

"If you use your lightning magic on her," I said, loosening my grip and giving him a perfectly faulty, panicked excuse, "your electricity will react with the necrotic acid in her veins. Her arm will literally explode."

Axel froze, his eyes widening. He immediately extinguished his magic and stepped back, looking at Scarlet’s arm with disgust.

"Fine." Axel spat. "Carry her yourself. But don’t you dare leave this spot. It’s my decision if we move."

I let out a slow, silent sigh.

This is going to be incredibly annoying.

If I had to baby him for every single step and guide his fragile ego, it was going to be a massive hassle. Figuring out a way to survive—finding clean water, edible food, structural protection, and engineering a chemical cure from raw dungeon materials—while simultaneously managing a delusional, arrogant brat like Axel was going to be frustratingly inefficient.

I needed him to think moving was his idea.

"You’re right. We should stay," I said, acting defeated. I paused, looking up at the ceiling. "Though... Rule 10 of Dungeon Survival is ’The way out is not where you came in.’ If the instructors are trying to dig us out, they won’t dig through Floor 10. The rubble is too thick."

Axel frowned. "What do you mean?"

"They’ll teleport to the emergency gate on Floor 20 and dig up," I lied smoothly, feeding his ego. "If we stay here, we’ll be waiting for weeks. But if we proceed down, we’ll meet them halfway. We’ll be rescued faster. But, like you said, it’s your call, leader."

Axel’s expression shifted from fear to arrogant calculation. He looked down the dark corridor, then back at me.

"Obviously, that’s what I was thinking," Axel scoffed, hoisting his axe onto his shoulder. "We’re moving to Floor 20. Pick her up and follow my lead. Don’t fall behind."

He marched into the darkness.

I easily scooped Scarlet into my arms, adjusting her head against my shoulder. I looked at her pale, pained face.

Hold on for a bit, Scarlet. I thought, stepping into the abyss. I’m going to cure you.

---

We walked deeper into Floor 11. The layout was chaotic, twisting into jagged, unnatural corridors.

As we walked, I carried Scarlet effortlessly, my mind running thousands of biological simulations.

Chemical denaturation using sulfur is risky. It could poison her blood.

How do you stop a microscopic protein chain from misfolding other proteins without a laboratory?

Proteases break down proteins. Decoy proteins can competitively inhibit active sites. Furthermore, the poison isn’t destroying her mana channels; it’s misfolding them.

I need a multi-pathway solution

Proteolytic Enzymes. I can extract digestive fluids from an acid-spitting monster to break down the prion.

Competitive Inhibition. Bone marrow extracts from immune monsters can flood her bloodstream with decoy proteins, stalling the virus.

Mana-Channel Stabilization. Celestial mana has an ordering property. If I crush luminous, celestial-aligned crystals into the solution, it will halt the misfolding cascade.

I just need to harvest the parts.

A guttural screech ripped through the corridor.

Six massive, hunched figures dropped from the stalactites. They were Grotesque Crawlers—blind, mutated subterranean beasts with acidic drool and razor-sharp mandibles. But they weren’t acting like mindless beasts. They fanned out in a perfect, coordinated semi-circle.

Axel stepped forward, his axe sparking. "More trash! Out of my way!"

He swung wildly, unleashing a wave of electricity. But the Crawlers didn’t just blindly rush him. They dodged, using the cavern walls to flank him. A larger, darker Crawler—the Alpha—barked a raspy command, and three of the beasts lunged at Axel simultaneously.

Axel barely parried the first strike. A mandible clipped his shoulder, tearing his uniform. He stumbled backward, swinging his axe in a desperate arc. Another Crawler swept his legs, throwing him hard onto the stone floor.

"Get off me!" Axel screamed, genuine fear bleeding into his voice as he blasted a point-blank lightning bolt to force the beast away. He scrambled backward, panting heavily, bleeding from three different cuts. His arrogant facade was cracking under the sheer, coordinated pressure.

I stood ten feet back, holding Scarlet, watching the fight analytically.

These monsters are working together in coordinated groups. Different species. That’s odd. What if they follow some sort of code? A Predation Cascade.

Axel scrambled to his feet, gripping his axe with white knuckles. He was terrifyingly close to being overwhelmed.

Then, the Alpha Crawler stepped forward. It ignored Axel entirely and stared directly into my eyes.

I didn’t move. I didn’t tense. I simply stared back, my breathing perfectly even, my posture completely guardless.

The Alpha froze. It let out a low, terrified whine, its mandibles clicking rapidly.

Then, it turned and scurried back into the shadows. The rest of the pack instantly followed, retreating into the darkness in seconds.

Axel fell to his knees, gasping for air.

"Yeah! That’s right! Run!" Axel roared at the empty corridor, trying to mask his terror with false bravado. He turned to me, spitting blood on the floor. "I sent them all packing. They attacked me because I’m the strongest! You should be grateful I’m here to protect you, useless."

I looked at him.

Weak monsters follow a leader to hunt weaker prey. They attacked Axel because he was swinging wildly, leaking erratic, fearful mana. He acted like prey. But when the leader looked at my completely guardless stance and absolute lack of physiological fear, its predatory instincts warned it of an apex predator.

It retreated because of me.

"Wow!" I said, giving him a comedic, deadpan glaze. "You’re so strong!!

Axel smirked, wiping his chin. "Damn right."

The next three hours were a chaotic, fast-paced blur of going in circles.

Floor 11 was a labyrinth, and the monsters kept repeating the exact same pattern: they ambushed us, overwhelmed Axel, beat him to a pulp, stared at me, and immediately retreated.

While Axel was busy getting thrown into walls and screaming about his lightning prowess, I went to work.

Every time Axel killed one before they retreated, I quietly stepped over to the corpse.

I snapped a razor-sharp, six-inch monster claw and slipped it into my pocket.

"Axel." I called out lazily. "Blast that rock over there. Make sure nothing is hiding behind it."

Axel angrily shot a bolt of lightning at the stone, heating it to a glowing red. I casually ran the monster claw through the residual heat, sterilizing it instantly.

I found a smooth, concave stone bowl and sealed the microscopic cracks with melted earwax from a dead bat-beast.

I ripped a hollow fang from a serpent’s jaw and chewed some tree resin to create an airtight seal at the base, carving a stick wrapped in cloth to act as a plunger.

I cut the bladder out of a Crawler, draining it to keep the thin, semi-permeable membrane.

"Axel." I called out lazily. "Shock that Crawler corpse. I think it’s still moving."

Axel blasted the corpse. The intense heat cooked the internal organs, allowing me to easily extract the pancreatic digestive fluids and the bone marrow without dealing with toxic blood spray. I scraped luminous crystal shards from the walls, grinding them down with the hilt of my dagger as we walked.

By the fourth hour, my bag was full. I had everything I needed.

Axel, however, had reached his breaking point.

He collapsed against a cavern wall, his uniform shredded, his face heavily bruised, and his chest heaving. "This dungeon is unfair!" he screamed, throwing his axe against the floor. "It’s completely rigged! Why haven’t they attacked you once?!"

"I’m carrying the dead weight," I said mildly. "They probably think I’m not a threat."

Axel growled. He raised his glowing hand toward his own bleeding shoulder. "I need to heal myself."

"Don’t." I interrupted smoothly. "Your mana will deplete too fast. We don’t know how long we’ll be down here. You need your reserves to fight."

Actually, I need your lightning to control the heat for my chemical reactions later. You can’t waste a single drop.

That was the final straw.

Axel snapped. He lunged forward, grabbing the front of my shirt.

"You arrogant dog!" Axel spat, his eyes wide with furious, humiliated rage. "Who do you think you are?! You’ve done jackshit since we got down here!"

I stared at him, my expression blank.

"You’re wasting the air around you!" Axel screamed, shaking me. "I’m carrying this whole team! I’m doing all the fighting! I’m taking all the hits! And you just stand there, picking up literal garbage off the floor!"

He shoved me back, though I didn’t actually lose my balance.

"You’re pathetic!" Axel raged, his voice echoing loudly off the cavern walls. "You’re nothing! You’re a useless, talentless straggler, and I should just leave you and the Elf here to rot!"

I opened my mouth to give him another mild, comedic gaslighting response, but the words died in my throat.

The air pressure in the cavern suddenly plummeted.

A heavy, suffocating aura pressed down on us from the darkness ahead. It was a menacing, overwhelming presence that made the hairs on the back of my neck stand up. The bioluminescent moss on the walls instantly died, plunging the corridor into pitch black.

Something massive was breathing in the dark.

The shadows peeled back.

From the pitch-black corridor, the Grotesque Crawlers emerged again. But this time, they hadn’t come to ambush and retreat. They had returned with the rest of the hive.

Dozens of red, glowing eyes pierced the darkness. The horde was massive. There were the blind Crawlers we had fought earlier, mixed with heavily armored carapace-beetles, and sleek, acidic spitters that clung to the ceiling. And at the center of the horde stood the Alpha—a towering, four-armed monstrosity with jagged bone plates and a jaw that unhinged into a gaping, drooling maw.

Axel’s axe dropped an inch. His hands were violently trembling.

"No..." Axel whispered, stepping backward until his spine hit the stone wall. "No, no, no... This is a Floor 12 horde. What are they doing up here?! How many are there?!"

The Alpha shrieked, a deafening sound that rattled my teeth, and the horde surged forward.

"Get away from me!" Axel screamed, unleashing a massive, blinding wave of lightning.

It fried the first three Crawlers, but the horde didn’t flinch. They swarmed him with terrifying coordination. The armored beetles locked their shields together, absorbing his lightning strikes, while the spitters rained acidic bile from above, melting the stone around his boots. The Crawlers flanked him, slashing at his legs.

"Help me!" Axel cried out, swinging his axe in a wild, desperate frenzy. His voice broke, stripping away all the arrogant bravado. "Please! Somebody, get them off me! I don’t want to die! Stop! Stop it!"

He was a scared, terrified child playing protagonist.

A Crawler lunged, its mandible sinking deep into his thigh. Axel screamed in agony, falling to his knees as the horde closed in to tear him apart.

I watched him quietly.

Well... I thought, gently setting Scarlet down against a safe section of the wall.

A terrified joker can’t really do much with my secret anyway.

I drew my twin daggers from my waist.

I kicked off the ground, the stone cracking under the sheer kinetic force of my physical strength.

I moved so fast the air itself whistled. I plunged into the horde like a silver blur. My daggers became a whirlwind of precision and lethal geometry. I ducked under an armored beetle, slicing its unprotected underbelly, then pivoted, decapitating two Crawlers before their bodies even hit the floor.

From Axel’s perspective on the ground, it must have looked like a meat grinder had materialized in the cavern. Flying heads, severed limbs, and fountains of dark blood sprayed across the walls. In exactly sixty seconds, the horde of forty monsters was reduced to a pile of twitching, dismembered corpses.

Only the Alpha remained.

It took one look at the massacre, let out a pathetic whine, and turned to flee into the dark.

I sheathed my twin daggers. Reaching into my dimensional ring, I pulled out a weapon I hadn’t used in a long time.

A Kyoketsu-shoge.

It was a traditional, brutal assassination weapon—a long, heavy metal chain with a heavy iron ring at the bottom, and a vicious, hooked dagger attached to the top handle.

I spun the chain, the iron ring whistling through the air, and threw the hooked blade. The blade sank deep into the Alpha’s retreating shoulder. I yanked the chain backward with bone-snapping force.

The Alpha roared in pain as it was dragged backward, its feet scraping against the stone.

I closed the distance in a single leap. I whipped the chain around its remaining arms, binding them tight, then pulled the dagger free. With a surgical slice, I severed both of its primary arms at the joint.

The beast fell to its knees. I didn’t stop.

I grabbed it by the thick, bony plates on the back of its head. I slammed its face into the cavern floor. Once. Twice. The stone cracked. Three times. Four times. I kept slamming its head down with ruthless, piston-like physical strength until the skull caved in completely, leaving nothing but a pulverized mess.

Perfect. I thought, letting out an excited breath.

I dug my fingers into the ruined skull and ripped out the thick, gooey cerebral membrane. Dark, sticky blood squished between my fingers, completely staining the sleeves and front of my academy coat.

I turned around and walked slowly toward Axel.

Axel was pressed against the wall, clutching his bleeding leg. He looked at the massacre, then looked at me, his eyes wide with absolute, pants-wetting terror.

"Wh-What the hell are you?!" Axel stammered, scrambling backward like a cornered rat. "How did you do that?! You don’t have any mana!"

"Are you even a student?! Why the hell did you hide this?!

What do you want from me?!"

I stopped a few feet away from him, holding the dripping, bloody brain membrane in my hand. My expression was perfectly blank, my eyes cold and dead.

"I like to keep my secrets." I said, my voice eerily calm, letting the threat hang heavy in the dark air.

"If you breathe a word of this to anyone, I will bash your brain in exactly like I did to that monster."

Axel violently nodded, swallowing hard. "I won’t! I swear to God, I won’t say anything! Please spare me! I’m sorry!"

Honestly... Fighting the urge to smile. I only ripped this gross membrane out for dramatic effect. It’s completely useless for the cure. But holding a bloody brain really sells the psycho-killer aesthetic.

"Just listen to my orders." I said coldly, tossing the membrane aside and wiping my bloody hands on a rag.

"And I will ensure you survive."

"I will! Whatever you say!" Axel pleaded. "What do we do now?!"

"Now, you gotta sleep." I said.

I stepped forward, reaching out toward him.

Driven by pure panic and primal fear, Axel’s survival instinct kicked in. He screamed, throwing a desperate, lightning-infused punch at my face.

It was pitifully slow.

I casually deflected his fist with the back of my hand, parried his secondary strike, and stepped into his guard. I drove the heel of my palm sharply into the carotid artery on the side of his neck.

Axel’s eyes rolled back into his head, and he collapsed onto the cavern floor, out cold.

I sighed, rolling my shoulders. I was going to need to find a secure place to rest, gather clean water, and secure actual food. It didn’t feel like it, given the constant adrenaline, but it had been hours since the collapse.

I walked back over to Scarlet. She was still breathing, but her skin was incredibly hot to the touch. I had been feeding her tiny, concentrated drops of a crushed alkaline-mineral paste I had made earlier to slightly slow the necrotic growth, but it was just a band-aid.

It wasn’t enough. I needed to finish the chemical cure soon.

I stretched my neck, hearing a satisfying pop.

I suppose I’ll try a little. I thought, picking her back up into my arms.

---

Perspective: Axel

My head throbbed with a dull, heavy ache.

I groaned, rolling onto my side. The cold, unforgiving stone of the dungeon floor pressed against my cheek. As my vision slowly swam into focus, the first thing I noticed was the warm, flickering orange glow of a fire.

A fire? Down here?

I sat up, rubbing the back of my neck where a sharp, lingering bruise pulsed. Across the small, enclosed cavern, Scarlet was resting on a bed of soft, dry moss. Her arm was elevated. She looked terrible, her face clenching in pain even in her sleep, but what shocked me was the crude medical setup surrounding her.

Hollowed fangs, tied with strips of cloth and sealed with tree resin, were taped to her arm. A thick, crushed mineral paste was slowly dripping into the purple, poison wound. It looked like a makeshift hospital built out of garbage and monster parts.

And sitting by the fire, casually roasting meat on a stick, was the useless extra. Kaiser.

My immediate instinct was anger. This arrogant loser knocked me out! Who does he think he—

Then, the memory hit me like a physical blow.

The silver blur. The meat grinder. Flying heads and severed arms. The way he grabbed a highrank Alpha by the back of the skull and pulverized its face into the stone with ruthless, mechanical piston strikes. The dripping, gooey brain matter sliding between his fingers as his dead, cold eyes looked directly into my soul.

Compared to him, I looked like an amateur swinging a toy.

He was a terrifying invisible assassin wearing a school uniform. I could not afford to make an enemy out of him.

I scrambled to my feet, my heart pounding in my chest. I marched over, ready to demand answers, but as I opened my mouth, my survival instincts hijacked my vocal cords.

"S-Sir?" I croaked.

Kaiser paused mid-bite, holding a skewer of roasted meat. He looked up at me, genuinely surprised by the sudden shift in tone. He chewed slowly, swallowed, and raised an eyebrow.

"You’re awake." Kaiser said, his voice returning to that mild, infuriatingly calm tone. "Good. It’s been 12 hours."

"12 hours?!" I choked, my eyes widening. "Are you insane?! We’ve been sitting in the dark for 12 hours?!"

I looked around the cavern properly for the first time, dumbfounded. It wasn’t just a fire.

The entrances to the cavern were meticulously blocked with precise stacks of loose rocks, creating a perimeter alarm system. In the corner, a crude water filtration system was bubbling.

Kaiser had taken two stone containers and placed a flat, clean piece of metal—a broken sword blade—angled between them above the heat source. Steam was hitting the cold blade and dripping perfectly clear water into the second bowl.Beside it sat a hollowed-out subterranean bamboo shoot stuffed with crushed, blackened bone fragments.

Kaiser casually picked up a stone cup, scooped some of the clear water, and took a drink.

"Distillation." Kaiser explained, noticing my blank stare. "Boil the water, collect the steam, pass it through a bone-charcoal filter. Activated carbon absorbs toxins. You should drink some. Dehydration will kill you faster than the monsters."

I just stared at him. "What... what are you eating?"

"Food procurement." Kaiser replied, holding up the stick. "Grotesque Crawler thigh meat and cave mushrooms. I crushed some mineral licks for salt and electrolytes."

"You’re eating a monster?!" I yelled, stepping back. "That’s toxic! You’re going to get magical poisoning! We’ll die!"

"You would, if you ate a mana-rich organ." Kaiser corrected gently. "I selected meat from creatures with simple digestive systems to minimize bioaccumulation. The mushrooms were grown on clean stone, not waste. And it’s thoroughly cooked. We are currently on Floor 12, Axel. I carried both of you down here to a defensible alcove. If we don’t eat, we starve."

He reached into his coat and tossed a piece of dried animal skin at my feet. It was covered in charcoal markings.

"What is this?" I asked, picking it up.

"A map of the next three floors, along with the monster hierarchy and spawn timings." Kaiser said, taking another bite of his barbecue.

My jaw physically dropped. "How... how could you possibly know what’s on the next three floors? We just got here! And you don’t have mana detection!"

"Dungeons are systems, Axel. Systems have rules." Kaiser explained, as if lecturing a toddler. "Acoustic mapping. While you were asleep, I hummed at different frequencies down the corridors. Changes in the echo pitch reveal hidden chambers and room sizes. I threw crushed dust to track air currents for ventilation and traps. I touched the walls—thermal mapping tells you if a heat source or a monster nest is nearby."

He pointed to the bioluminescent moss on the walls.

"Light patterns." Kaiser continued. "The moss dims when monsters are active because they absorb the ambient mana. Bright moss means a safe corridor. Dim moss means danger. And spawn timings are simple math—if a room is empty when you enter but full when you return, the spawn window is the time you were gone. I’ve charted the safest path to Floor 15."

Kaiser finished his explanation, took another bite of his mushroom and meat skewer, and chewed peacefully, staring into the fire.

I stood there, holding the map, my hands shaking.

My face felt numb. My brain couldn’t process what I was looking at.

He scouted three floors ahead. He mapped out traps, calculated monster spawn rates, engineered a medical drip for Scarlet, built a perimeter defense, distilled pure water, and cooked a safe, nutritious meal. All in 12 hours. Without using a single drop of magic.

What kind of monster is this guy?! I thought, a cold sweat breaking out on the back of my neck. He’s younger than me. He’s supposed to be a talentless straggler from Class C. But his combat is ruthless, and his intelligence... it’s otherworldly.

I swallowed my pride, clutching the crude map tightly.

I’m not the alpha anymore. I’m just the luggage.

"How is she?" I asked, my voice barely a whisper. I looked over at Scarlet. Her breathing had become even more shallow, her chest barely rising, and a soft, pained wheeze escaped her throat with every breath. "Is she... going to make it?"

Kaiser didn’t look up from Scarlet’s arm. He was holding a sharpened, sterilized monster claw, gently probing the edges of the purple discoloration.

"Her metabolic rate is slowing, which is buying us time. But it’s a temporary plateau."

He pointed a bloody finger toward the sandy ground beside him. "Look at that."

I stepped closer, squinting in the dim firelight. Scrawled into the dirt with a thin stick were columns of incredibly dense, bizarre symbols. It wasn’t magic. It was math. But it was unlike any math I had ever seen at the academy.

`d[P]/dt = k1 [P] [P]^2 - (V_max [P]) / (K_m + [P*])`

`ln(k / T) = -(dH / R) * (1 / T) + ln(k_B / h) + (dS / R)`

It went on and on, sprawling across the sand with variables I didn’t recognize—subscripts of molecular weights, kinetic constants, thermodynamic values, and fluid dynamics equations for blood viscosity.

"What is this?" I murmured, my head spinning just looking at the equations.

"Scarlet’s diagnosis." Kaiser said calmly, wiping the monster claw on a rag.

"The poison isn’t a simple toxic compound. It’s a structural pathogen. A misfolded protein agent—a prion—fused with a necrotic viral strain. It uses her own body’s proteins as templates to force further misfolding, specifically targeting her neural pathways and mana channels. Standard magical healing is useless because it only accelerates cellular division, which exponentially increases the replication rate of the misfolded proteins."

I blinked, trying to process the words. I remembered a few things from the basic biology lectures the academy nurses gave us when we got injured in training.

"Wait... if it’s a misfolded protein, you can’t just fix that. The nurse said you need highly specialized equipment to even identify protein structures. You need a high-speed centrifuge to isolate the serum, a high-magnification microscope to see the cellular damage, and a sterile syringe to run blood filtration. It’s impossible down here. We have nothing."

"I already built them." Kaiser said.

He gestured to the corner of the cave. I followed his gaze and felt my stomach drop.

There, resting on a flat rock, was a crude contraption. It was a clear, prism-like crystal shard, ground down so precisely it looked polished, placed over a flat stone with a single, perfectly spherical water droplet sitting on top of it.

Beside it lay a hollowed-out monster fang, fitted with a plunger made from a carved wooden stick wrapped in a tight cloth seal. Next to that was a thin, translucent membrane—the bladder of a Crawler—suspended over a stone bowl.

"The water droplet acts as a crude high-magnification lens when combined with the crystal’s refraction."

Kaiser explained, his voice entirely detached. "It’s enough to inspect the blood cell lysis. The Crawler bladder is a semi-permeable membrane—I’m using it as a dialysis filter to strain out the larger necrotic cellular debris. And I can spin the serum in a stone bowl suspended by fibers at a calculated RPM to separate the components. I don’t need a lab."

"I just need some basic resources to work with."

I stared at the makeshift medical gear, then at the boy sitting before me. My mind felt completely fractured.

Who is he? How does a talentless Class C student know how to construct a functioning dialysis filter and microscope out of monster guts and stones? The sheer, terrifying gap between our capabilities made my own elven lineage and high magic score feel like an absolute joke.

"If I had a fully equipped laboratory." Kaiser continued, scrawling another set of variables in the sand, "I could isolate the exact compound using the language of chemistry or biochemistry. But we don’t have weeks. Her nervous system will collapse entirely in less than four hours."

"So, I bypassed the chemistry."

"You bypassed it?"

"I solved it with mathematics." Kaiser said, his eyes scanning the equations.

"I’m calculating the exact thermodynamic transition states. If I can determine the precise activation energy needed to break the disulfide bonds holding the misfolded protein chains together, I can formulate a specific ratio of volcanic sulfur, crushed berry acid, and mineral salts to denature the prion without destroying her blood cells."

He quickly wrote out another sequence:

`R-S-S-R + 2 R’-SH <==> R’-S-S-R’ + 2 R-SH`

`dG = -R T ln(K_eq)`

"It’s a probability calculation of molecular collisions in a non-Newtonian fluid." He muttered.

"I’m mentally simulating the reaction now."

My knees fell.

I sank to the cold stone floor, the map slipping from my fingers. The sheer weight of our situation, the suffocating darkness of Floor 12, and the terrifying realization of our isolation hit me all at once.

"Why..." My voice broke, tears of frustration and terror welling in my eyes. "Why hasn’t the academy rescued us yet? The instructors... Theodor, Columbina, the Principal... they’re S-rank mages! They should have cleared the rubble hours ago! Why are we still down here?! Are they just going to leave us to die in the dark?!"

I clutched my head, my breaths coming in short, panicked gasps.

The arrogance I had carried for years was completely gone, leaving only a terrified teenager trapped in the deep abyss.

"Why do you act like that?" Kaiser’s voice suddenly cut through the heavy silence.

I looked up, my eyes red and stinging. He wasn’t looking at me with pity or disgust. He was just observing me, spinning a sharpened piece of bone between his fingers.

"Like what?" I snapped, my defensive instincts flaring up, though it sounded weak even to my own ears.

"Like a bully with something to prove," Kaiser said mildly. "You bark louder than you bite. You pretend to be a weapon, but the moment you face real pressure, you retreat and blame others. Why?"

I swallowed hard, looking away, staring into the flickering flames. The fire illuminated the dark, damp cavern walls, making the shadows dance.

"Because I hate it." I admitted, my voice trembling. "I hate being looked down on. My family isn’t some elite lineage. I’m just a regular guy with lightning magic. If you don’t act like you’re the strongest, people will just crush you. They’ll use you. You have to be loud, or you become a victim."

Kaiser hummed thoughtfully. "That’s why you joined Milo’s group."

I flinched.

"It makes sense." Kaiser continued, leaning back against the cavern wall. "Milo is rich, arrogant, and loud. He draws all the negative attention. By standing behind him, you get the protection of his status, and you get to act tough without actually having to carry the burden of leadership. You get the benefits of the gang without the true risks."

"That’s not true! I joined because we’re friends! I’m not hiding behind anyone, I’m Class C’s secret... weapon!"

"Friends? Milo treats you like a dog. You accept it because being a lapdog is safer than standing on your own two feet."

"You don’t know anything about me! I was going to prove myself to everyone! To Elfina!"

"Elfie? A girl like Elfie will never look at a sore loser who hides behind a louder dog just to feel big. She sees right through you. Everyone does."

"Shut up! You don’t know what it’s like!"

"If you keep letting your arrogance dictate your actions, you’re going to die down here."

"You’ll die alone, suffocated by your own delusions, while the rest of the world moves on without even remembering your name."

"That’s the reality, isn’t it?"

Tears finally spilled over my cheeks. I wiped at them furiously, but they kept coming. The dam had broken.

"Okay fine! I’m scared!" I sobbed, my chest heaving as the crushing reality of the dungeon pressed in on me.

"What if they don’t come?" I cried, my voice cracking. "What if the rescue team takes weeks?! We’re going to die down here! I don’t want to die in the dark!"

"I’ve been relying on you because you seem to know everything, but we can’t survive forever! The monsters keep getting stronger, the food will run out, and I can’t even fight a single horde without getting mauled! We’re dead, Kaiser, we’re already dead!"

I buried my face in my hands, crying like a child.

"You are a coward." Kaiser said, his voice flat.

I choked on a sob, expecting him to tear me apart.

"But..." Kaiser continued, his tone softening just a fraction, "there isn’t a single person in this academy who wouldn’t be afraid down here. Fear is a response to the unknown. It’s fine to be terrified of the dark. It’s fine to be weak. What’s pathetic is letting that fear paralyze you when you still have breath in your lungs."

I sniffled, looking up at him through my fingers.

Kaiser stood up, walking over to me. He knelt down so he was at eye level.

"I need your strength, Axel." Kaiser said, his expression completely serious. "I can’t navigate this dungeon alone. We need to reach Floor 20 to find a stable exit point."

I wiped my nose, shaking my head in confusion. "What strength? I’m useless. You surpass me in literally everything. You fight better, you’re smarter, you don’t even use magic... I have nothing you need."

"That is partially incorrect." Kaiser replied. "I need your lightning magic. I don’t have mana. Without your electricity, I can’t generate the specific temperatures required for Scarlet’s chemical cure. Without your light, navigating the deeper floors is suicide. And once we get her stabilized, I can use your electrical output to restructure the Lumina device and try to establish communication with the instructors."

Kaiser extended a hand toward me.

"Here is the deal." Kaiser said. "You lend me your magic, and you follow my orders without question. In return, I will keep you safe. And when we make it out of here, you can take all the glory and attention for keeping us alive."

I stared at his hand.

For the first time since I came to Asura Academy, I didn’t feel like I had to lie. I felt humbly seen, completely understood, and oddly safe.

Kaiser wasn’t just a classmate anymore. In the dim light of the dungeon, he looked like a hero. An absolute idol.

I reached out and grabbed his hand—not just with one hand, but with both of mine, clutching it tightly as tears streamed down my face again.

"Please don’t look at me, sir." I blubbered comically, dropping to my knees while still holding his hand. "I’m just a humble wolf."

Kaiser stared at me, his eyes widening in profound, deadpan shock.

"Please, tell me where to stand." I continued, sobbing loudly. "I’ll hold the bags. I’ll carry the snacks. Whatever you need! Just... please don’t make me go first anymore. I now fully understand my place in the food chain."

Kaiser tried to pull his hand away, but I was gripping it like a lifeline.

"What happened to being the secret weapon?" Kaiser asked, his stoic facade cracking into a look of genuine comedic bewilderment.

"I am but a humble wolf in your shadow, sir!" I declared, sniffling loudly.

Kaiser stared at me for a long second. Then, despite himself, he let out a short, quiet laugh.

I let go of his hand, wiping my eyes, and found myself laughing too. It was a hysterical, exhausted, terrified laugh, but it was real. In the middle of Floor 12, surrounded by darkness and monsters, we just laughed.

Perspective: Elfie

1:14 AM.

The candle on my desk flickered, casting long, erratic shadows across the walls of my dorm room.

My fingers were bleeding. I hadn’t noticed when I started biting my nails, but the metallic taste of blood was pooling on my tongue.

I didn’t care. I stared at the blank piece of paper on my desk, my mind spinning at a thousand miles an hour.

Wait.

That’s what the instructors had told us. Theodor. Columbina. Aisha. Sukuna. The S-rank elite mages of Asura Academy. They said the spatial anomaly was too unstable, the rubble was too dense, and trying to force a path down would cause a complete cave-in. They told me to go back to my dorm and wait.

Are you kidding me?

A dark, violent static buzzed behind my eyes. The polite, cheerful side of me that I wore for the academy was melting off, leaving behind the ruined, abandoned girl from the orphanage.

The girl who only had one thing in the world.

"If he dies, I’ll kill them all," a voice whispered in the darkest corner of my mind. "I’ll burn this academy to the ground. I’ll rip the dungeon apart floor by floor until the sky bleeds."

"Calm down, Elfie. When you overthink, your head gets too hot."

Kaiser’s voice echoed in my memory, the phantom sensation of his hand patting my head trying to soothe the erratic thumping of my heart.

Shut up! I snarled internally, my pink eyes glowing faintly in the candlelight. I can’t calm down! You’re down there! You’re in the dark! What if you’re bleeding? What if you’re hurt?!

I needed a solution. Now.

I grabbed a quill, aggressively scratching ink onto the parchment.

Path 1: Physical Excavation. I could use high-density Celestial Magic to vaporize the collapsed bedrock or supernova it.

Result: The shockwave would collapse the lower floors. It could crush him. Useless.

Path 2: Spatial Manipulation. I could force a tear in the dimensional fabric, bypassing the physical rubble entirely.

Result: Without a guiding point, the tear could spit me out randomly. I could end up inside a wall, or worse, I could accidentally open a vacuum near Kai and rip him apart. Too dangerous.

Path 3: A Direct Portal. I had done it before. During the entrance exam, I accidentally warped the space to find him. It wasn’t a spatial tear; it was a targeted fold in reality. But to fold reality, you need two points. Point A is me. Point B is... where?

How do I find his exact location?! The Lumina devices were blocked. The magical signatures were scrambled. I had no coordinates.

Think. Think! What connects us?

I stood up, pacing the room like a caged animal. My eyes darted around, landing on the small, worn canvas bag sitting in the corner of my closet. It was the bag we brought from the orphanage. The only things we truly owned.

I rushed over, tearing the bag open. My hands dug through the worn clothes and old trinkets until my fingers brushed against cold metal.

I pulled it out.

A small, intricately carved ring.

The Sea of the Heart.

We had found it together years ago. It carried a trace of our bond from years of being near each other.

I slipped the ring onto my finger. It fit perfectly.

A terrifying, obsessive warmth flooded my chest. Mine! A possessive, manic smile pulling at the corners of my lips.

This is our connection. Our soulmate thread. It doesn’t matter how much interference the dungeon puts up. You can’t block a soul.

I pressed the ring against my lips, my eyes widening as the chaotic swirl of my mana began to align.

"If you can visualize infinity." Kai had once told me while we were lying on the roof of the orphanage, looking at the stars, "Then theoretically, your mind encompasses infinity. And if you are infinity, nothing can touch you."

I am infinity. I thought, my pink eyes glowing brighter, casting an ethereal, terrifying light across the dark room.

I will fold infinity to find you, Kai.

I didn’t care about the rules. I didn’t care about the structural integrity of the dungeon. If any monster down there dared to lay a single claw on him... if the dungeon made him bleed even a single drop... I would tear the fabric of reality itself to shreds and erase the very concept of their existence.

Hold on, Kai/ My magic spiraling into a violent, concentrated singularity around the wooden ring.

I’m coming.
