The bells did not stop.
Their sound rolled through the industrial district like the heartbeat of something buried deep inside the Damocles. Slow. Heavy. Ancient enough to feel wrong.
Kain stood motionless on the shaking walkway while red warning lights pulsed through clouds of steam around him.
The surviving students had already started retreating.
Not carefully.
Urgently.
The armored student backed away first, grabbing the wounded third member by the shoulder.
"Move," he snapped.
The injured student stared once at the corpse bleeding across the metal grating beside Kain.
Then they ran.
Kain frowned slightly.
They had numbers. Weapons. Experience.
Yet the moment the bells started ringing, fighting stopped mattering.
That bothered him more than the attack itself.
Another vibration rolled beneath the floor.
This time stronger.
The industrial corridor groaned violently.
Metal screamed somewhere below.
Then the entire walkway shifted sideways.
Kain immediately grabbed the railing as the floor tilted several degrees to the left. Steam burst from overhead pipes in violent white jets while warning sirens screamed through the sector.
A mechanical voice crackled overhead through damaged speakers.
"ROTATION CYCLE COMMENCING."
Static.
Then silence again.
Kain looked upward sharply.
Far above the steam clouds, massive gears were moving behind the walls.
Not small machinery.
Entire sections of the district were rotating.
The realization settled heavily in his chest.
The Damocles was changing shape.
A deafening metallic impact echoed through the corridor ahead as two gigantic blast doors slammed shut. Catwalks folded inward mechanically while rail systems shifted overhead with thunderous force.
Kain stepped backward instinctively.
The floor beneath him lurched.
Then started moving.
Fast.
The entire maintenance walkway began sliding sideways into the wall structure like a retracting platform.
Kain broke into a sprint immediately.
Steam exploded around him as the narrowing corridor collapsed section by section behind him. Thick industrial chains moved through the ceiling above like mechanical serpents, dragging entire platforms upward into darkness.
The air smelled like overheated metal and oil.
Ahead, another student was running too.
A girl with short silver hair and a torn black uniform vaulted over a collapsing railing before glancing back toward Kain.
Their eyes met briefly.
Not enemies.
Not allies either.
Just two people trying not to die.
The corridor suddenly split apart between them.
Massive gears rotated beneath the floor.
The girl barely jumped across the widening gap.
Kain followed instantly.
Pain detonated through his ribs the moment he landed.
His injured side nearly gave out beneath him.
The silver-haired student noticed.
"You're still moving with injuries like that?"
Kain said nothing.
Another explosion rattled the sector.
The walls began rotating inward.
Not metaphorically.
The actual corridor twisted sideways around them.
The girl cursed under her breath.
"Lower sectors are cycling already."
Kain finally spoke.
"What is Rotation?"
She looked at him strangely while sprinting.
"You really are fresh."
A metal beam suddenly crashed through the ceiling ahead of them.
Both moved instantly.
The girl rolled beneath it.
Kain vaulted sideways onto an emergency ladder bolted against the wall just as the floor section behind him collapsed into darkness.
Heat surged upward from below.
He looked down briefly.
Gigantic turbines spun beneath the district.
Thousands of meters deep.
One fall would liquefy a human body instantly.
The girl climbed onto the ladder platform beside him breathing hard.
"You don't know the rules," she muttered.
Kain glanced at her.
"I know people keep trying to kill me."
"That's normal."
The answer came too quickly.
Too casually.
The fortress shook again.
Somewhere nearby, someone screamed.
Then the sound cut off abruptly.
The silver-haired student immediately stiffened.
"Run."
"Why?"
She looked toward the darkness below the turbines.
Then back at him.
"Because the sectors that fail Rotation get recycled."
Kain narrowed his eyes slightly.
"What does that mean?"
But she was already moving again.
—
Rain hammered Greenveil harder now.
The overgrown district looked almost submerged beneath the storm.
Yuri sprinted through flooded streets while red emergency lights flickered behind layers of vines and shattered buildings. Water splashed violently around his legs every time he turned a corner.
The hunters were still behind him.
Closer now.
He could hear them moving across rooftops above the flooded streets.
Fast.
Coordinated.
Yuri slid beneath a collapsed bus stop just as several thin blades embedded themselves into the concrete wall behind him.
No warning.
No shouting.
Just killing intent.
He forced himself forward breathing unevenly.
His shoulder was getting worse.
Every time he used too much ice, pain surged through his arm hard enough to make his fingers numb.
The district trembled suddenly.
Yuri stopped.
The sound of grinding metal echoed beneath Greenveil.
Then the street ahead split open.
A massive steel wall rose slowly from beneath the flooded roadway, covered in moss and hanging vines. Ancient mechanical locks rotated loudly inside it while floodgates opened somewhere deeper in the district.
Water levels immediately began rising.
Yuri stared.
The district itself was changing.
"What the hell…"
A voice echoed from somewhere above.
"Cut him off at the eastern channels!"
Another voice answered from farther away.
"He's moving toward Transit Seven!"
Transit?
Yuri looked ahead.
Beyond the rising floodwaters, old rail structures stretched through the district beneath layers of vegetation.
They were herding him.
The realization hit immediately.
Not random attacks anymore.
They were forcing him somewhere.
Yuri backed away instinctively.
Then heard movement behind him too.
More students emerging from the flooded streets.
Three.
No.
Five.
Different uniforms.
Different weapons.
Working together anyway.
One girl holding a spear pointed toward Yuri silently.
Another student adjusted wires wrapped around his hands.
None of them looked excited.
Just focused.
Like workers finishing a task.
The rain intensified.
Water climbed past Yuri's knees now.
Cold currents swirled around his legs.
Responsive.
Dangerously responsive.
The spear-user suddenly rushed first.
Yuri reacted instantly.
Ice erupted across the water surface in jagged patterns as he slid sideways beneath the incoming strike. The spear scraped sparks against frozen pavement while Yuri slammed his palm downward.
A wall of ice burst upward between them.
The other students attacked immediately.
Thin metallic wires sliced through the forming ice from the side.
Another participant leapt over the barrier entirely.
Yuri barely blocked a knife strike with his forearm.
Pain shot through his arm.
The attacker twisted midair trying to stab downward again—
Yuri released freezing air point blank into his chest.
The student's body instantly lost momentum.
Ice spread across his torso.
Then the attacker fell backward directly into the floodwater.
Frozen spikes erupted upward unconsciously beneath him.
One punched through his stomach.
The water turned dark red.
Yuri froze.
The student stared upward silently for several seconds.
Alive.
Then not.
Everything around Yuri became quieter suddenly.
The remaining hunters stopped moving.
Not afraid.
Watching him differently now.
The spear-user lowered her weapon slightly.
"…Sixty-three," she muttered.
Yuri's chest tightened.
How did they—
A flicker of blue light reflected across the flooded street.
Yuri looked sideways.
A broken LCD screen mounted against a collapsed train station flickered weakly through static.
063
The number glowed briefly beside his distorted reflection.
Then disappeared.
The hunters moved again instantly.
Yuri turned and ran.
—
Elsewhere deep inside Greenveil, dozens of terrified participants hid inside an abandoned underground transit station.
Some were injured.
Some crying quietly.
Some simply staring blankly at the red emergency lights flickering overhead.
Fresh drops.
Yuri stumbled into the station half-soaked and breathing hard before immediately stopping.
Everyone looked at him.
The atmosphere shifted instantly.
One participant whispered something under their breath.
Another backed away slightly.
Yuri frowned.
"What?"
Nobody answered.
Then a boy sitting against the far wall slowly looked up.
Young.
Brown jacket soaked with blood.
Fresh scars running across his throat.
Recognition hit Yuri immediately.
Impossible recognition.
The river.
The corpse he saw earlier floating downstream.
The boy stared directly at him.
"You saw me die."
The station went silent.
Yuri's stomach dropped.
The boy touched the scar along his throat casually.
"Hurt less the second time."
Nobody reacted.
Not even surprised.
Yuri looked around wildly.
"What do you mean second time?"
No answer.
Only silence.
Then—
The entire station shook violently.
Red lights flared brighter overhead.
A mechanical alarm screamed through the tunnels.
Several participants panicked instantly.
One girl started crying.
Another participant grabbed his backpack and bolted toward the exits.
The boy against the wall stood slowly.
Expression blank.
"Rotation reached Greenveil."
Yuri grabbed his arm immediately.
"What happens during Rotation?"
The boy looked at him strangely.
Like the question itself was absurd.
Then the station lights died completely.
Darkness swallowed everything.
And somewhere deep beneath the flooded district—
Something enormous moved.
