Harem System in an Elite Academy-Chapter 226: Phase Four Deepens: Pressure Without Witness

The gate did not open immediately.

Arios stood on the platform, waiting, his breathing steady but measured. The dungeon's response time had always been deliberate, as if it needed to assess something before deciding what to do next. The faint glow of the sigils carved into the stone gate pulsed once, dimmed, then pulsed again, brighter this time.

The floor beneath Arios vibrated lightly.

He shifted his stance, rolling his shoulders and adjusting his grip on his sword. The fatigue in his muscles was real now. Not debilitating, but persistent. The kind that didn't go away with a few deep breaths. His uniform was scuffed, sleeves torn at the edges, boots marked with dried blood that wasn't his.

The gate finally moved.

Stone slid aside with a deep grinding sound, the two halves separating just enough to allow passage. Cold air spilled out from beyond, carrying a scent that wasn't damp stone or mana residue.

It smelled metallic.

Arios stepped through without hesitation.

The gate sealed shut behind him the moment he crossed the threshold, cutting off the platform and replacing the ambient echo of the previous chamber with something tighter, more enclosed. This new corridor was narrower, walls close enough that he could touch both sides if he extended his arms. The ceiling was low, forcing him to keep his head slightly down.

Light came from thin slits in the walls, arranged in uneven vertical lines. They flickered irregularly, never fully stabilizing.

This wasn't a combat corridor.

It was a compression corridor.

Arios advanced slowly, senses stretched outward. The dungeon's mana density here was higher, pressing against his skin like static. It wasn't hostile, but it wasn't passive either. It reacted subtly to his presence, shifting intensity whenever his mana output fluctuated.

He reduced his flow further, relying more on physical awareness.

After several minutes of walking, the corridor opened abruptly into a wide chamber.

Arios stopped at the threshold.

The room was circular, its diameter large enough to fit a training field. The floor was smooth, unbroken stone, polished to a dull sheen. The walls rose high, curving inward toward a domed ceiling. There were no visible exits besides the corridor he'd entered from.

At the center of the room stood a single structure.

A pillar.

It was tall, thick, and layered with engraved symbols that ran vertically along its surface. Unlike the earlier sigils, these were inactive—dark, inert, as if waiting.

Arios stepped into the chamber.

The moment his boot touched the floor, the symbols on the pillar ignited.

Light raced upward along the engravings, converging near the top. The air vibrated sharply, and Arios felt a brief, intense pressure press down on his shoulders.

Then the floor shifted.

Segments of stone slid apart, rearranging themselves into raised platforms and shallow depressions. The chamber transformed in seconds, the once-flat surface becoming an uneven terrain of elevation changes and narrow paths.

Arios scanned the room quickly.

Still no visible enemies.

That didn't mean safety.

The pillar at the center pulsed again.

From the shadows near the walls, movement began.

Figures emerged slowly, stepping into the light one by one.

They were humanoid, similar in build to the earlier constructs, but more refined. Their bodies were made of dark, matte stone, joints reinforced with glowing lines of mana. Their faces were featureless, smooth except for faint indentations where eyes might have been.

There were six of them.

They spread out evenly, positioning themselves around the chamber, blocking any direct path back to the entrance.

Arios exhaled.

"Group engagement," he muttered.

The constructs didn't rush him.

Instead, they advanced in sync, measured steps echoing softly against the stone. Their movements were coordinated, each one adjusting position relative to the others.

Formation-based enemies.

Arios moved first.

He sprinted toward the nearest construct on his left, sword raised. The construct reacted instantly, stepping back while another moved to intercept from the side. Arios altered course mid-stride, cutting toward the second one instead.

His blade struck the construct's torso, sparks flying as metal met reinforced stone. The impact pushed it back, but didn't break it.

Before the others could converge, Arios disengaged, rolling away and putting distance between himself and the group.

They reformed immediately, tightening their formation.

This wasn't about raw damage.

It was about control.

Arios circled the chamber, forcing the constructs to adjust constantly. He kept moving, never allowing them to surround him fully. His eyes tracked each one, noting subtle differences in mana output.

Two of them had stronger signatures.

Likely anchors.

He feinted toward the left, drawing three constructs with him, then abruptly changed direction and charged the right side. His sword flashed, striking low, then high, targeting the glowing mana lines rather than the stone itself.

The first anchor staggered as the line cracked.

The formation faltered.

Arios pressed the advantage, moving aggressively now. He struck again, this time driving his blade into the joint at the construct's shoulder. The stone shattered, the arm dropping uselessly.

The others reacted faster this time.

One slammed into Arios from behind, sending him skidding across the stone. He rolled, came up on one knee, and blocked a downward strike with the flat of his blade. The impact jarred his arms, but he held.

He kicked the construct's knee, knocking it off balance, then finished it with a thrust through the chest.

The remaining constructs hesitated for half a second.

That was all Arios needed.

He moved through them methodically, exploiting the weakened formation. Without both anchors, their coordination degraded rapidly. One by one, he dismantled them, targeting joints, cores, and mana lines until only rubble remained.

The chamber fell silent again.

The pillar at the center dimmed.

Arios stood still for several seconds, letting his heart rate settle. Sweat ran down his back, his breathing heavier now, but controlled.

He approached the pillar cautiously.

As he drew closer, the surface of the stone rippled slightly, and a panel slid open near its base. Inside was a small recess containing a crystal the size of his fist. It glowed faintly, its mana signature stable and contained.

A checkpoint core.

Arios reached out and touched it.

Warmth spread through his palm, followed by a subtle replenishment of mana. Not a full recovery, but enough to take the edge off.

A low chime echoed through the chamber.

PHASE FOUR — MIDPOINT CONFIRMED.

CONTINUATION AUTHORIZED.

The floor shifted again.

This time, a section near the far wall lowered, revealing a descending passage.

Arios didn't linger.

He moved toward the new path, stepping into the darkness beyond.

The descent was gradual, the passage sloping downward rather than dropping sharply. The air grew colder with each step, and the mana density increased again, pressing against him more noticeably now.

After several minutes, the passage opened into another chamber.

This one was different from the rest.

It wasn't stone.

The walls were made of something translucent, like hardened glass infused with mana. Faint shapes moved within them, distorted silhouettes that shifted slowly, as if suspended in liquid.

Arios slowed.

The floor was smooth, reflective, mirroring the walls faintly. His own reflection stared back at him, distorted by the uneven surface.

At the center of the room stood nothing.

No pillar. No enemies.

Just empty space.

Arios stepped forward cautiously.

The moment he crossed the center point, the room reacted.

The walls pulsed, and the shapes within them surged outward, pressing against the surface. The reflections on the floor warped violently, and Arios felt a sharp spike of mana pressure hit his senses.

Then the shapes emerged.

They tore free from the walls, bodies forming mid-motion. These weren't constructs.

They were beasts.

Large, quadrupedal creatures with elongated bodies and multiple limbs. Their skin shimmered with the same translucent quality as the walls, making it difficult to track their exact movements. Their eyes glowed faintly, fixed on Arios.

Three of them surrounded him almost instantly.

Arios drew a steady breath.

His muscles protested as he raised his sword again, but he ignored it. Fatigue was expected. Hesitation wasn't allowed.

The first beast lunged.

Arios sidestepped, slashing as it passed. His blade connected, but the creature's body distorted around the impact, absorbing some of the force. It recoiled, not injured enough to stop.

The second came from the side, jaws snapping. Arios ducked under it and drove his shoulder into its flank, using momentum to knock it off balance. He followed with a downward strike, targeting where the neck should have been.

The third circled, waiting.

Arios repositioned, keeping all three in his field of view. He adjusted his approach, focusing less on raw cuts and more on destabilizing their mana cohesion. Each strike was aimed at disrupting flow rather than inflicting immediate damage.

Gradually, it worked.

The beasts' movements became erratic, forms flickering as their structure destabilized. One collapsed into a heap of dissolving mana, its body breaking apart into light.

The second followed moments later.

The third let out a low, distorted sound and retreated briefly, then charged again.

Arios met it head-on.

Their collision sent a shockwave through the chamber. Arios gritted his teeth and pushed forward, driving his blade deep into the creature's core. This time, the form couldn't hold.

It shattered.

The chamber quieted.

The walls solidified again, the translucent material returning to its inert state. The floor stopped reflecting.

Arios straightened slowly, chest rising and falling more noticeably now. His arms felt heavy, legs stiff.

But he was still standing.

A new passage opened on the far side of the chamber, narrower than the last.

Arios wiped his blade clean and moved on.

Phase Four wasn't finished yet.

And the dungeon had made one thing clear.

It wasn't testing his strength anymore.

It was testing how long he could keep going.
