Harem System in an Elite Academy-Chapter 228: Phase Four Deepens: Pressure Without Release

The hum beneath Arios's boots did not stop.

It didn't intensify either. It stayed steady, low, persistent, like a reminder that the dungeon was still active and watching. The circular room remained unchanged for several breaths after he stepped onto the platform. No light flared. No announcement echoed. No mechanism revealed itself immediately.

Arios stood still, shoulders squared, sword resting loosely in his grip.

He waited.

Nothing happened.

That, more than anything else, made him uneasy.

He stepped off the platform and circled the room once, inspecting the walls. The stone here was smoother than in previous sections, less fractured. Faint mana veins ran beneath the surface, thin and orderly, unlike the chaotic flows in earlier chambers.

"This isn't a checkpoint," he muttered. "It's a buffer."

The realization settled slowly.

The dungeon wasn't giving him a reward. It was giving him time.

Time to breathe. Time to reset. Time to let exhaustion catch up.

Arios exhaled through his nose and leaned back against the wall, sliding down until he was sitting. He didn't close his eyes. He loosened his grip on the sword but kept it within reach.

His muscles ached in a dull, accumulated way. Not injury. Wear.

He rolled his shoulders once, then twice, testing range of motion. Still good. His breathing steadied gradually. The mental fog that had been creeping in receded slightly.

Minutes passed.

Then the hum changed.

Not louder—deeper.

The platform at the center of the room sank a few inches, stone grinding softly. From the wall opposite the entrance, a new passage opened, the stone folding inward smoothly.

Arios stood immediately.

"No free breaks," he said quietly.

He stepped into the new corridor.

This one was wider, taller. The ceiling arched overhead, supported by thick stone ribs that gave the impression of walking through the inside of something massive. The mana here flowed in slow currents, drifting rather than pressing.

The floor sloped gently upward.

Good and bad.

Good because it meant progress. Bad because climbing, even shallow inclines, taxed already tired legs. 𝙛𝒓𝓮𝒆𝔀𝒆𝙗𝓷𝒐𝙫𝒆𝙡.𝒄𝓸𝓶

Arios maintained a steady pace, refusing to rush. His boots echoed faintly with each step, the sound swallowed quickly by the space around him.

After several minutes, he noticed movement.

Not ahead.

Above.

He stopped and looked up.

Shapes clung to the ribs along the ceiling—long-limbed creatures with pale, stretched bodies and jointed limbs that bent at wrong angles. Their faces were smooth, featureless except for shallow slits where mouths might be.

They hadn't attacked yet.

They were watching.

Arios adjusted his stance slightly, shifting weight to the balls of his feet. He raised his sword just enough to be ready without provoking.

He took another step.

The creatures moved in response, crawling along the stone, repositioning but still keeping distance.

He took another step.

One dropped.

It fell silently, landing behind him.

Arios spun instantly, blade flashing. He cut through the creature's torso mid-lunge. The body collapsed without a sound, dissolving into gray residue.

The others reacted.

Three dropped at once.

Arios backed toward the wall, keeping them in front of him. He slashed at the first, ducked under the second, kicked the third away before it could latch onto him.

More dropped.

They didn't swarm mindlessly. They attacked in staggered waves, forcing him to keep moving, keep turning.

This wasn't a strength test.

It was a focus test.

Arios conserved his energy, avoiding wide swings. Short cuts. Precise thrusts. He let momentum do most of the work.

When the last creature fell, he stood still, listening.

Nothing followed.

The corridor continued upward.

Arios wiped sweat from his brow with the back of his wrist and moved on.

The next chamber was smaller, circular again, but unlike the previous one, this one was cluttered. Broken stone, scattered bones—some animal, some not—and several rusted weapons lay half-buried in the floor.

He scanned the remains carefully.

Old.

Very old.

This room had seen repeated use.

The air here smelled faintly metallic.

Arios stepped carefully between the debris. His foot brushed against a cracked helmet, sending it rolling. The sound echoed louder than expected.

From behind a pile of rubble, something stirred.

Arios turned, sword ready.

A low growl filled the room.

A creature emerged—canine in shape but wrong in proportion. Its body was elongated, ribs visible beneath taut skin. Its eyes glowed dimly, unfocused yet locked onto him.

Then another.

Then another.

Three total.

Not dire wolves.

Something thinner. Faster.

They circled slowly, testing distance.

Arios didn't wait.

He advanced instead.

The first lunged. Arios sidestepped and cut across its shoulder, spinning with the motion to face the second. He blocked its bite with the flat of his blade and drove a knee into its chest, sending it skidding back.

The third went for his legs.

Arios jumped, brought his blade down, and pinned it to the floor. He twisted, ending it quickly.

The remaining two hesitated.

He pressed the advantage, forcing them back, cutting them down one after the other.

Silence returned.

Arios stood amid the debris, chest rising and falling steadily. He felt heavier now. Each fight added weight that didn't leave afterward.

He moved to the far side of the chamber.

Another corridor awaited.

This one descended.

Of course it did.

Arios followed it down, steps careful on the uneven slope. The temperature rose slightly as he descended, the air growing thicker again.

By the time he reached the bottom, he was sweating openly.

The next chamber was long and rectangular, with a shallow pool of dark water stretching across most of the floor. Stone platforms protruded at irregular intervals, creating a possible path across.

Arios crouched at the edge and studied the water.

No ripples.

No visible movement.

Too still.

He picked up a loose stone and tossed it in.

The water swallowed it without a splash.

Arios frowned.

He stepped onto the first platform.

Nothing happened.

He moved to the second.

Still nothing.

Halfway across, the water stirred.

A shape moved beneath the surface, long and serpentine.

Arios jumped to the next platform just as something burst from the water behind him—a massive eel-like creature with a wide, circular mouth lined with teeth.

It snapped shut where his leg had been a moment earlier.

Arios didn't hesitate. He leapt forward, skipping a platform and landing hard on the next. The creature surged again, following.

He ran.

The platforms forced him to pace his steps carefully, but he pushed, leaping where necessary. The creature lunged repeatedly, missing by narrow margins.

At the final platform, Arios turned.

He waited.

When the creature rose again, he drove his sword straight into its mouth. The blade pierced through, pinning it briefly.

The creature thrashed, tearing itself free, but the damage was done. It sank back into the water, darkening it with spreading clouds.

Arios crossed the final stretch and exited the chamber without looking back.

The corridor beyond was short.

It ended at another circular room, this one empty except for a single stone door.

Arios approached it slowly.

He placed a hand on the surface.

Warm.

Active.

The door began to open.

Beyond it, the dungeon waited.

Phase Four wasn't finished.

But Arios was still standing.

And he stepped forward anyway.
