Boom.

  The steel door behind Z-69 slammed shut with a deep, metallic finality, the sound rolling through the chamber like someone knocking on the lid of a buried coffin.

  For a brief moment, the echo was the only thing alive in the room.

  He stood in the center of a cylindrical chamber.

  The walls were forged from dark red metal, their surfaces broken by branching veins of molten orange light that pulsed slowly, like artificial blood flowing under steel skin.

  No wind.

  No scent.

  No sound.

  Except the faint, irregular thud of something trying to remember how to be a heartbeat inside his chest.

  A relic of a time when he had still been human.

  The lights in the ceiling flickered.

  Small circular fixtures bloomed to life one by one, forming a halo of pale yellow illumination that seemed too weak for a place like this.

  Then the system voice spoke.

  Distorted. Fragmented. Like a recording that had been played through rust for a century.

  “Floor 3: PRESSURE.”

  “Assessment parameters: Extreme pressure. Physical durability. Willpower endurance.”

  Z-69 didn’t move.

  He remembered Elise’s “guide”—a brief file she’d handed him with that faint, dangerous smile of hers.

  Her notes on this floor had been blunt:

  Artificial pressure chamber.

  Simulates deep-space compression and high-density reactor environments.

  Each cycle squeezes the body until internal organs burst.

  There are only two options:

  Destroy the control core or get turned into meat paste.

  That was for normal contestants.

  He was not normal.

  He couldn’t die in any conventional sense.

  But he could still be crushed—turned into a pile of twitching flesh glued to the floor.

  Annoying.

  Time-consuming.

  And very, very messy.

  He took one step forward.

  The chamber inhaled.

  A violent PHSSSSSHHH erupted around him, like thousands of pistons firing at once and pressing inward.

  The pressure hit him so suddenly that if he still relied on breathing, his lungs would have imploded.

  The invisible force clamped down on his entire body.

  His ribcage creaked like old wood.

  His artificial joints groaned.

  Somewhere inside his chest, vertebrae whispered under the strain.

  The violet crystal embedded in the center of his sternum flared instinctively—a flash of deep amethyst light that radiated into his limbs, reinforcing tissue and forcing broken structures to hold.

  Z-69’s body reacted on its own.

  His mind lagged behind by half a heartbeat.

  He pulled in a breath out of habit.

  No air entered.

  “Right.” he thought calmly. “I don’t need to breathe.”

  He reminded his body of this obsolete human instinct and took another step.

  The walls began to vibrate.

  Thin slits opened along the upper rim of the cylindrical chamber.

  From inside those slits, something emerged—a swarm of coal-black military drones, unfolding like mechanical locusts awakened after long dormancy.

  They dropped from the openings and stabilized midair in perfect formation, their rotors spinning so fast the blades blurred.

  The sound they produced was not the usual whine of cheap security drones.

  This was a shriek.

  Refined.

  Sharpened.

  A weaponized scream of machines built for war.

  Red targeting lasers flicked on, crisscrossing the chamber and converging on the single figure standing at its center.

  Z-69.

  A cold secondary voice—colder than the system—spoke from within the swarm:

  “Target identified: Contestant Number 69.”

  “Threat classification: Unknown. Regeneration abnormal.”

  “Elimination priority: Level 1.”

  Z-69 lifted his head slightly.

  “Of course it is.” he said.

  His tone was closer to boredom than fear.

  The drones attacked.

  The first wave unleashed a barrage of plasma cutters, thin streams of superheated energy that carved scorched lines across the floor where he had been standing milliseconds earlier.

  The second wave fired railgun projectiles, needle-thin metal slugs propelled at speeds fast enough to pierce tank armor.

  The third wave deployed high-pressure injection darts—designed not to kill, but to rupture internal organs and cause catastrophic internal bleeding.

  The chamber rang with noise:

  plasma sizzles, metallic impacts, the scraping of steel on steel as shots that missed buried themselves in the walls.

  Z-69 moved.

  Or at least, he tried to.

  Pressure climbed again—without warning.

  It felt like the room had grabbed his entire body and shoved it into a vice.

  His joints locked.

  His knees dipped.

  Support the creativity of authors by visiting the original site for this novel and more.

  One of the bones in his right leg fractured with a faint, brittle tch.

  Under normal circumstances, he would have blurred out of target lock.

  Here, even he felt slow.

  The violet crystal pulsed harder, repairing microfractures before they could fully spread.

  But regeneration had a price.

  His wristband—flashed yellow, then a deeper orange.

  Energy consumption rising too quickly.

  He couldn’t afford to go wild here.

  Z-69’s lips tightened.

  He couldn’t use electricity.

  In a stable environment, his lightning arced cleanly from point A to point B.

  Under this kind of shifting pressure, where density changed unpredictably, any high-voltage discharge might rebound into his own body, frying his internal systems and overloading the crystal.

  Right now, The Hunger was already restless.

  So he had only one option:

  Cold. Hard. Steel.

  The Heaven-Sundering Blade spun once in his hand.

  The first drone that flew into range split cleanly in two.

  The corpse slammed into his chest a fraction of a second later, rammed by the same pressure that had slowed him.

  The impact knocked his left shoulder half out of socket.

  He twisted his arm—

  Click.

  The joint snapped back into place.

  Three more drones dove at him.

  The blade flashed.

  One metal body fell with a hole where its core used to be.

  The second lost its rotors and spun into a wall.

  The third managed to drive a spike into his side before being decapitated by a reverse slash.

  Z-69 staggered—not from pain, but from the accumulating force around him.

  Pressure pressed him toward the floor.

  It was like walking underwater with a mountain strapped to his back.

  He reached into a compartment near his waist armor and tore open a sealed packet—John’s high-energy dried meat.

  The salty, metallic smell of condensed nutrients hit his nose.

  He bit down.

  Hard.

  The food tasted like someone had concentrated an entire meal into a single piece of jerky, then added pure battery acid for fun.

  The energy hit him seconds later.

  His crystal drank it greedily.

  The wristband blinked back to yellow.

  “Barely.” he thought.

  He had a total of ten packets.

  He had just used one.

  Up in the ceiling, the system voice spoke again:

  “Pressure increasing by 40%. Next cycle commencing.”

  The room clenched.

  Z-69 heard his own spine complain—a series of faint cracking sounds, like ice breaking underfoot.

  His outer layer of skin, already dead tissue, stretched and strained, revealing glimpses of gray muscle and alloy beneath.

  The drones continued their assault.

  They weren’t infinite, but they were smart.

  They adjusted to his rhythms quickly:

  One unit baited him with a frontal rush.

  Another circled to flank his blind spot.

  A third hovered above, waiting for him to commit before firing downward.

  Z-69 dispatched them one by one, but each movement cost more than the last.

  His regeneration fought constantly against pressure damage.

  His crystal burned fuel faster and faster.

  He opened a second packet of meat and swallowed it in three bites.

  The Hunger stirred.

  He felt it like claws dragging along the inside of his skull.

  “Stay down.” he murmured, not to the drones, not to the chamber—

  But to the thing sharing his body.

  His wristband flared a deeper orange.

  Another wave of pressure.

  His chest flattened against his sternum.

  The chamber floor became a giant hand pressing up against his body, trying to merge him with the metal.

  His bones, his tendons, his implants, his artificial modifications—everything screamed silently as they were forced into shapes they were never meant to hold.

  His muscles tore.

  The crystal mended them.

  They tore again.

  They mended again.

  Loops of destruction and repair ran faster and faster, like some mad god had dumped his entire system into an overclocking experiment.

  He needed to end this.

  He needed the core.

  Every pressure chamber had one—the control heart that modulated all cycles.

  Destroy it, and the floor ended.

  Where?

  He looked up at the walls.

  The orange veins of light brightened in pulses, in sync with the pressure cycles.

  The light patterns were irregular, like faulty wiring, but…

  Something else bothered him—his senses were fogging.

  Even with his enhanced perception, it was hard to distinguish structural vibrations from pure pressure feedback.

  His steps grew heavier.

  His mind felt like it was sinking into thick oil.

  “Eat more?”

  “No. Supplies limited.”

  “Eat less?”

  “Then you break faster.”

  Two bad choices.

  He picked the one that let him move.

  He tore open a third packet—only half this time—and forced himself to chew even as pressure tried to split his jaw.

  Energy flowed in—but so did something else.

  Hunger.

  Not metaphorical.

  Real.

  Gnawing.

  “Feed me.” a voice whispered from deep inside his chest.

  Not heard with ears, but echoed through his nerves.

  He ignored it.

  The system voice rang out again, louder than before:

  “Pressure cycle escalation: 85%.”

  He barely stayed on his feet.

  His knees buckled.

  Purple blotches spread across his skin as capillaries burst under the relentless crushing force.

  One drone slipped through his guard.

  The plasma cutter carved open half his left shoulder in a diagonal line.

  Flesh cooked, then vaporized.

  The violet crystal flared in a desperate surge, knitting him back together in real time, glowing so brightly he could see its shine under his own skin.

  His head spun.

  His fingers felt distant, numb.

  The fourth energy packet slipped from his grip.

  He didn’t even feel it fall.

  His vision dimmed—not from blood loss, but from system overload.

  Pressure climbed again.

  Final cycle.

  Something in his back gave way.

  CRACK.

  His spine snapped in two.

  His body collapsed, flattened against the floor like scrap.

  The crystal in his chest formed a hairline fracture.

  And somewhere deep in the void of his fading consciousness—

  Laughter.

  Ugly. Wild. Hungry.

  Not his.

  Never his.

  The Hunger.

  The other thing that lived inside the crystal with him.

  “My turn.”

  His awareness flickered out.

  Z-69 died—not in body, not in truth, but in control.

  Something else stood up in his place.

  It rose.

  Bones reknit with disgusting speed.

  Muscles snapped back like thick cords pulled taut.

  Veins darkened, bulging against the skin like black roots.

  The eyes that opened were not Z-69’s.

  Same shape. Same color.

  But wrong.

  Too sharp. Too bright. Too alive.

  The Hunger scanned the chamber.

  Pressure slammed into it.

  It laughed.

  A low, guttural sound—not fully human, not fully monstrous, like an engine misfiring and enjoying the chaos.

  Its back straightened fully under the crushing force.

  Its neck rolled.

  Its hands flexed lazily, as if testing the weight of the air.

  A drone surged forward, needles extended.

  The Hunger caught it barehanded.

  No technique.

  No style.

  Just fingers.

  It squeezed.

  Metal screamed.

  The drone imploded, pieces raining down in slow motion.

  A laser beam shot directly into its face.

  The Hunger tilted its head.

  The beam grazed past, searing plumes of smoke from dead tissue.

  It smiled.

  Then bit into the barrel of the firing drone’s weapon.

  With a single wrench of its jaw, it tore the entire emitter off.

  Pressure increased again—a brutal squeeze meant to crush what was left.

  Bones popped.

  Muscles stretched too far.

  Internal structure distorted—The Hunger grew stronger.

  It didn’t care about organs.

  Didn’t care about bones lining up properly.

  The crystal pumped energy into whatever shape it wore, and it fought in that shape.

  Drones charged.

  The Hunger met them with bare violence.

  It ripped mechanical limbs off and used them as clubs.

  It slammed drone bodies together until sparks rained down like metallic rain.

  It stomped shattered cores into the floor just because it enjoyed the cracking noise.

  Every second of fight fed it more.

  Its instincts sharpened beyond anything Z-69’s rational mind could access.

  Through the storm of pressure and debris, The Hunger sensed it.

  A different rhythm.

  A different vibration.

  The heartbeat of the floor.

  The core.

  Hidden behind a thick section of wall—buried like a secret heart behind ribs of steel.

  The Hunger turned toward the source.

  The wall was half a meter of reinforced alloy.

  The first punch dented it.

  The second cracked it.

  The third tore a hole big enough to step through.

  It didn’t hesitate.

  It entered the hidden core chamber.

  Inside, the room was smaller—pulsing red from a single energy node floating in the center, suspended in a magnetic field. It throbbed like a heart made of plasma, cables feeding into it from every direction.

  The Hunger approached.

  It could have sliced it.

  Crushed it.

  Ripped it apart.

  Instead, it wrapped its fingers around the core like a starving predator finally finding something worth eating.

  And it ate.

  Its jaw unhinged, teeth sinking into the glowing surface.

  The core shattered into a burst of red light.

  The energy didn’t explode outward.

  It flowed inward.

  Into the crystal.

  Into The Hunger.

  For a moment, entire Floor 3 went white.

  Pressure died.

  Drones fell from the air like dead flies, hitting the floor in a chorus of dull, lifeless thuds.

  The swirling lights in the walls went dark.

  The system voice cut out mid-sentence.

  Silence rushed in like a tide.

  The Hunger licked the last traces of red radiance from its lips.

  It turned its gaze toward the exit—a massive triple-layered blast door at the far end of the chamber.

  It walked.

  Placed its hands on the door.

  Pulled.

  Steel groaned.

  Bolts screamed.

  Reinforcements tore free, bending and snapping like dry twigs.

  The blast door, designed to withstand military artillery, gave way under raw, unnatural strength.

  The Hunger stepped onto the staircase leading upward.

  Floor 4 waited.

  As it crossed the threshold, the crystal in its chest flared one more time—pulsing with stolen core energy—then dimmed.

  The violet light in its eyes flickered.

  Z-69 woke up.

  He stood on the stairway, one hand against the wall, the other still stained with drone oil and dried purple blood.

  His body ached in strange ways.

  Not the simple pain of crushed bone or torn flesh.

  But the empty-burn sensation of having been used too far, too fast.

  He looked back.

  The blast door behind him was torn open like cardboard.

  The chamber beyond was a mess of broken drones, ripped panels, and claw marks etched deep into steel walls.

  He tasted metal in his mouth.

  Copper. Ash. And something… hot.

  Inside his chest, the crystal hummed quietly.

  Full.

  More full than before.

  It pulsed with an unfamiliar pattern—energy that wasn’t his.

  He didn’t remember the details.

  But he knew exactly who had done this.

  A voice that wasn’t quite a voice slithered up from the depths of his mind:

  “I’m hungry. Feed me more…”

  Z-69 closed his eyes.

  Not in fear.

  In exhaustion.

  Being possessed by one’s own power was tedious.

  He opened them again.

  The stairs to Floor 4 stretched upward into an orange glow—another trial, another machine, another trap waiting to grind him apart.

  He tightened his grip on the Heaven-Sundering Blade.

  His body was damaged.

  His energy reserves were warped.

  His sanity was playing tug-of-war with a monster sharing his core.

  Even so—he climbed.

  Because that was the only direction left.

  Up.
