The Three-Second Rule: My Death Game System

The metallic screech of train wheels grinding against aging tracks snapped Kael awake.

He was sitting on a cold, hard plastic seat. The fluorescent lights overhead flickered violently, casting long, erratic shadows across the empty subway car.

Wait. Not empty.

Three other people were in the carriage: a businessman gripping a leather briefcase, a teenager in a faded hoodie, and a terrified-looking woman clutching her purse. None of them spoke. The air was incredibly heavy, thick with an unnatural, freezing chill that seeped into their bones.

Where am I? Kael thought, his head throbbing. He took the subway every day, but this train—with its rusted doors and blood-red handrails—was entirely alien.

Suddenly, the train's intercom crackled to life. It wasn't the usual automated transit announcement. The voice was mechanical, synthetic, and completely devoid of human emotion.

"Attention passengers. The train is about to enter the Abyssal Tunnel. Rule Number One: When the darkness falls, close your eyes. Hold your breath. Do not open your eyes, and do not exhale, until the lights return. Violators will be terminated."

The businessman stood up, his face red with sudden anger. "What kind of sick prank is this? I have a board meeting in—"

The lights instantly cut out. Pitch blackness swallowed the carriage.

Kael didn't hesitate. His survival instincts, honed by years of living on the edge, screamed at him. He clamped his eyes shut and held his breath, pressing both hands hard over his mouth and nose.

In the suffocating darkness, the sound of the grinding tracks vanished. A deadly, absolute silence fell over the train.

Then, a wet, heavy thud. Something had entered the carriage.

The temperature plummeted. Kael could feel a freezing aura sweeping past him, smelling of rot and old iron.

"I... I can't..." the teenager gasped, his panic breaking his breath.

A sickening CRUNCH echoed through the dark. It sounded like a massive pair of industrial shears snapping through wet celery and bone. Warm liquid splattered violently across Kael’s face and jacket.

His heart hammered against his ribs. The terror was overwhelming. His lungs were burning, and his body was desperately trying to force him to gasp for air.

Suddenly, a blinding blue digital interface materialized behind his tightly shut eyelids.

Kael’s brain seized as a vivid, hyper-realistic vision forced its way into his mind: In exactly three seconds, his lungs burn too much. He lets out a tiny, involuntary exhale. A massive, pale hand with razor-sharp claws lunges from the darkness, piercing straight through his chest.

The vision vanished. He was back in the real darkness.

One second.

His lungs screamed for oxygen. The urge to exhale was pure agony.

Two seconds.

He knew the creature was standing directly in front of him, waiting for the slightest sound. Instead of trying to hold his breath normally, Kael bit down brutally on his own tongue. The sharp, metallic taste of blood and the sudden spike of pain overrode his body's reflex to gasp.

Three seconds.

A freezing gust of wind brushed inches past his face. The claws missed his flesh entirely, slicing deep into the plastic seat right beside his ear.

He had survived.

A mechanical hum resonated through the carriage, and the fluorescent lights violently flickered back to life.

Kael opened his eyes, gasping hungrily for air. The creature was gone.

The businessman was curled in a corner, weeping silently, his briefcase abandoned. The teenager was simply gone, leaving behind only a shredded hoodie and a massive, horrifying pool of crimson spreading across the floor.

Kael wiped the warm blood off his cheek, his eyes glowing with a faint, residual blue light.

The intercom crackled again.

"Rule Number One concluded. Excellent work, survivors. The train will now proceed to the next station."

"Rule Number Two: The passenger with the most blood on their clothes will be expelled from the train in sixty seconds. Good luck."

Kael looked down. Because he had been sitting closest to the teenager, his jacket was completely soaked in red.
