Chapter 76: The Piston Grid

The cavern violently shook.

Rolf’s brand new class skill was not just a loud noise. It was a physical shockwave of concentrated, peak C Grade mana.

The sound hit the towering Warden Construct like a solid iron battering ram.

KRRRRRNNNK!

The ancient machine violently stuttered.

The sheer magical pressure disrupted the ambient magic flowing through its weeping hydraulic joints.

The massive circular saw attached to its right arm ground to a halting, sparking stop.

While my pack sprang into action, my vision suddenly darkened. Time seemed to slow down to an absolute crawl as a massive, golden text box dominated my sight.

[Main Quest 1: Plug out the Continental Threat!!]

[Description: The Great Iron Labyrinth is a rogue planetary forge. A mechanical plague is festering at the bottom of the world. If the Origin Core is not manually disconnected, the endless army of machines will eventually rise and consume the continent.]

[Phase 1 Reward: 500 LP, Labyrinth EXP Multiplier Buff.]

[Grand Completion Reward: 100,000 LP, 1x A Grade Item Ticket, Title ’Savior of the Iron Heart’.]

’A hundred thousand points and an A Grade item? The System is practically begging me to clear this dungeon,’ I thought, my eyes widening at the absurd payout.

I focused my mind, initiating a direct mental link with the interface.

’System, explain something to me. This is a quest to save the continent from machines. Why am I being rewarded with Lust Points? There is nothing perverted about fighting a giant rusted robot.’

The golden text paused, then generated a new, highly detailed response.

[Answering Host. The System requires a thriving biological ecosystem to harvest conceptual currency. A mechanical apocalypse yields zero energy. You are being compensated to protect the System’s harvest grounds.]

’So I am just an exterminator keeping your farm safe?’ I challenged internally.

’But why use Lust Points to pay me for combat? It makes no sense.’

[Host misunderstands the nature of primal energy. The adrenaline of lethal combat, the absolute high of cheating death, and the biological imperative to propagate the species originate from the exact same core instinct. Violence and desire are two sides of the same biological coin. By conquering a lethal threat, you generate the required frequency.]

I stared at the glowing words. The sheer scale of what the System was implying was staggering.

’Are you a god? A parasite? What exactly are you?’ I demanded.

The golden text violently flickered, shifting into a corrupted, glitching font. White static filled my vision for a split second.

[Kzzzt... Error. Access Denied. Host lacks the required administrative clearance to comprehend this concept.]

[Reach Level 50 to unlock the true nature of the System and understand the power of Law.]

’The power of Law? Level 50?’ I realized, feeling a cold chill run down my spine.

The System was bound by rules I could not even begin to fathom yet.

I dismissed the notification, and time instantly snapped back to normal. I crossed my arms and leaned against the catwalk railing.

I was not going to lift a single finger in this fight. I needed to see exactly what my squad could do.

---

"Strike!" Rolf barked, his voice carrying unquestionable authority over the cavern.

Lysandra gasped as a heavy, golden aura washed over her. Her crippling fear vanished in an absolute instant. It was entirely replaced by boiling adrenaline and explosive energy.

’I am not afraid. I am going to tear that metal apart!’ Lysandra realized, her pink eyes flashing brilliantly.

Rolf did not wait for the others. He leaped directly off the high catwalk, falling toward the paralyzed machine like a silver meteor.

’[General’s Rend!]’ Rolf roared in his mind.

THUD!

He landed squarely on the construct’s sloped iron head. His heavy boots cracked the thick plating.

He reached down with his razor sharp silver claws and grabbed the thick hydraulic pistons connecting the saw arm to its shoulder.

SPLRRRSH! 𝒻𝘳𝘦𝘦𝘸ℯ𝒷𝘯𝘰𝑣ℯ𝑙.𝘤𝑜𝘮

With a brutal, primal heave, he ripped the pistons straight out of their sockets. Black machine oil sprayed everywhere like thick blood.

The massive circular saw completely detached and crashed to the stone floor.

"Now!" Rolf yelled, exposing the gaping hole in the machine’s armored chest.

Kaelith dropped from the shadows above.

She was a blur of lethal motion.

’[Midnight Eclipse!]’ she chanted internally, her twin blades glowing with dark mana.

She slashed in a rapid crossing pattern, completely destroying the glowing red optical sensor. The machine shrieked in mechanical agony, completely blinded.

Lysandra moved next. Her new technique was terrifyingly fast under the influence of the General’s buff. She darted across the stone floor, slipping right under the machine’s wildly flailing left claw.

’[Phantom Silk Sword Style: Severing Thread!]’

Lysandra commanded in her mind, focusing all her energy into the tip of her iron dagger.

She drove the blade deep into the exposed chest cavity, precisely slicing through the thick, glowing purple mana veins feeding the corrupted core.

ZZZZZZZ... POP!

The sickly purple light flickered rapidly and died.

The massive Warden Construct froze, let out one final puff of white steam from its exhaust pipes, and collapsed backward onto the cavern floor with a deafening crash.

I smiled from the catwalk.

They had completely obliterated a Strata 1 Mini Boss in less than thirty seconds without me even drawing my weapon.

[Phase 1: Boss Execution - Complete!]

[500 LP Awarded.]

[Labyrinth EXP Multiplier Buff Activated.]

[You have defeated a Strata 1 Warden Construct. Pack EXP distributed.]

A massive surge of pure, warm energy washed over my body.

’Leveling up after the Level 20 threshold is incredibly difficult. It usually takes months of grinding just to gain a single level. But these ancient Labyrinth monsters are absolutely stacked with raw experience points,’ I noted with deep satisfaction.

I walked down the metal stairs and approached the destroyed machine. I plunged my mechanical Vanguard Arm into the ruined chest cavity, searching the oily wreckage. My brass fingers closed around something heavy and warm.

I pulled out a perfectly intact, glowing blue cylinder.

"A High Density Mana Battery," Nyssa observed, hopping down the final few stairs to join me.

"Pure preindustrial Gnome tech. We can use that to power heavy siege equipment or massive magical barriers."

"Good. Stash it safely," I said, tossing the heavy cylinder to her.

With the Warden destroyed, the path to the lower levels was completely clear.

We walked past the mechanical carcass and stepped onto the massive industrial elevator platform sitting in the center of the room.

I grabbed the heavy, rusted activation lever and pulled it down with a sharp yank.

CLUNK. VRRRRRRRR.

The massive support chains groaned loudly, and the platform violently lurched downward. We were leaving the Rusted Shallows behind.

The descent was not entirely smooth.

The massive elevator platform rattled and shook as it dropped deeper into the crust of the earth. Sparks flew from the iron guide rails, casting brief flashes of yellow light across our faces.

"Gather around," I ordered, gesturing to the center of the large platform.

"The Shallows were just the front door. We need to prepare for what comes next."

Nyssa immediately unclipped the brass map drive from her satchel. She placed it on the floor of the elevator.

The device hummed, projecting the glowing blue holographic map into the dark air.

’The map is highly detailed, but the sheer complexity of the second floor is terrifying. It looks less like a dungeon and more like the inside of a massive clockwork engine.’

Nyssa manipulated the hologram, zooming in on the dense web of corridors below us.

"Welcome to Strata 2. The Piston Grid," Nyssa announced, her voice echoing over the grinding chains.

"This floor is entirely different from the Shallows. The environment down there is built for heavy manufacturing. The map shows constant mechanical movement."

"Define constant movement," Kaelith asked, kneeling to get a closer look at the projection.

"I mean the walls themselves are hazards," Nyssa explained, pointing to several red zones on the map.

"There are massive hydraulic crushers, shifting floor plates, and extreme heat vents. We will be fighting in a completely active factory."

Rolf cracked his metallic knuckles.

"I can take the heat. My new armor is heavily insulated."

"The heat is only part of the problem," I said, pointing to the dense cluster of tunnels.

"The noise down there is going to be entirely deafening. The grinding gears and steam vents will make verbal communication nearly impossible during combat."

Lysandra looked up, her pink eyes filled with a new, hardened focus.

"So how do we coordinate if we cannot hear each other?"

"We switch to hand signals and formation combat," I instructed.

I held up my hand, demonstrating basic tactical gestures.

Two fingers forward meant push.

A closed fist meant halt.

A flat palm slashing downward meant execute.

"Rolf," I said, turning to my new General.

"You are our anchor. You take the absolute front. In these tight, shifting corridors, we cannot afford to get flanked. Your job is to bottleneck the enemy."

"Understood, Grik," Rolf nodded, his silver fur catching the blue light of the map.

"Nyssa, you stay right behind Rolf," I continued.

"You are the primary navigator. Keep your eyes on the map and call out the environmental traps before we step on them."

"I will keep us out of the crushers," Nyssa confirmed, adjusting her leather goggles.

"Kaelith, Lysandra. You two take the flanks," I ordered.

"You are our mobile executioners. Rolf holds them in place, and you two use the walls and vertical space to rip them apart. Do not stay grounded for too long. If the floor plates shift, you need to be in the air."

’This formation plays perfectly to our individual strengths. Rolf is the immovable object, and the girls are the unstoppable force.’

"What is our primary objective for this floor?" Kaelith asked.

"Do we rush straight for the next elevator?"

"No," I smiled, feeling the residual warmth of the hidden System buff secretly flowing through my veins.

"We are not just passing through. This Labyrinth is an incredible training ground."

The pack looked at me, listening closely.

"We are going to hunt," I declared.

"We will systematically sweep the safe zones of the Piston Grid. The monsters here are incredibly strong, which means they are packed with raw energy. We will bleed this floor completely dry of experience before we even think about fighting the Phase 2 boss. We need to be vastly stronger before we hit the deeper levels."

Lysandra gripped her dagger tightly. The fear was completely gone, replaced by the eager anticipation of the hunt.

"Prepare yourselves," Rolf warned, looking over the edge of the platform.

The air grew instantly hotter, suffocatingly so. The grinding noise of a million moving parts suddenly echoed up from the terrifying abyss below us, hitting us like a physical wall of sound.

The elevator hit the bottom with a massive, bone rattling thud.

The heavy iron gates in front of us slowly cranked open, revealing a hellish landscape of glowing red iron, blinding steam, and the relentless, deafening rhythm of a planetary forge at work.
