The metal door slid open with a cold, razor-edged shhhhk—a sound sharp enough to cut the air in half.

  It wasn’t loud, but it carried weight, like the Tower itself exhaled and exposed another piece of its iron lungs.

  Z-69 stepped forward.

  A long cylindrical chamber stretched ahead, bathed in sickly strips of green light embedded high along the ceiling.

  The illumination was so faint it barely did more than sketch ghostlike lines across the metallic curvature of the room.

  Down the center of the chamber lay a single, impossibly thin walkway—A metal bridge, no wider than a pair of human feet, stretching across an abyss of swirling energy.

  Z-69’s eyes narrowed slightly.

  The moment he placed a boot on the platform, the space reacted.

  On both sides of the bridge, cyclones of compressed air spiraled upward in violent columns, sucking debris and dust upward with explosive ferocity.

  They weren’t just wind—they were engineered pressure funnels, rotating with precision, like industrial saws built from storms.

  A pebble, dislodged from the sole of Z-69’s boot, fell.

  For a brief millisecond he tracked its drop.

  The pebble touched the cyclone—and instantly shattered into powder, atomized into nothing.

  The Tower didn’t need to explain the risk here.

  The speaker still explained anyway:

  “FLOOR 2 – BALANCE.”

  “Assessment focus: Gravity, Orientation, Footing.”

  Even the voice sounded like it wanted him dead.

  Z-69 stepped onto the bridge.

  The metal felt cold—unnaturally cold—as if the bridge had no intention of welcoming him.

  He pressed his weight down lightly.

  No vibration.

  No settling.

  Perfectly stable.

  Which only made it more suspicious.

  Step one.

  Gravity amputated itself.

  Weight vanished.

  His body rose half a centimeter off the bridge, drifting like a loose sheet of paper.

  Z-69 stabbed the Heaven-Sundering Blade downward, anchoring himself to the metal by force.

  The purple spark that jolted up the hilt felt like a warning breath from The Hunger.

  He suppressed it.

  “Cute warm-up.” he murmured.

  Step two.

  Gravity collapsed downward at three times normal force.

  The bridge didn’t bend, but his knees buckled slightly as the weight slammed into his joints.

  His bones groaned quietly, and a faint crack formed near his ankle.

  A regular human would have collapsed.

  A gifted human would have screamed.

  Z-69 didn’t blink.

  Step three.

  Gravity twisted sideways.

  His entire body lurched left, dragged as if the universe tried to peel him off the walkway and feed him to the cyclone.

  He stabbed the blade into the walkway seam.

  This tale has been unlawfully lifted from Royal Road. If you spot it on Amazon, please report it.

  The impact sent a metallic tch reverberating through the bridge.

  Z-69’s lips tightened.

  “This floor wants me dead quickly.”

  He sounded almost amused.

  Then the bridge began to rotate.

  Slowly—

  Then faster—

  Until the walkway spun like the barrel of a massive revolver, threatening to throw him out with each shift.

  Wind surged from the far end of the chamber, a long, low roar like a pressure system collapsing.

  The cyclones grew louder, spiraling with increased violence.

  The entire chamber was becoming a storm engine.

  Z-69’s hair floated slightly under 0G fluctuations before whipping down again when gravity spiked.

  His zombie physiology wasn’t designed for subtle balance.

  He lacked certain reflexes humans used to instinctively stabilize themselves.

  But in return, he had—Combat instinct, muscle memory and an animal’s sense for survival.

  The bridge spun harder, tilting at angles that would force any normal contestant to crawl or cling.

  Z-69 walked.

  Not perfectly.

  Not effortlessly.

  But decisively.

  Each step was a controlled reaction, not a guess.

  His hips shifted automatically to adjust to invisible vectors.

  His spine bent exactly the right number of degrees to counter sudden gravitational pulls.

  His grip tightened on the blade only when needed—not one motion wasted.

  Halfway across—Gravity flipped to 0.2G.

  His body drifted again.

  This time the wind tugged at him strongly—a warning that losing footing now meant death.

  Z-69 dug his heel into the bridge.

  Even in low gravity, the subtle shift of weight allowed him to redirect his center of balance.

  He pulled himself down with controlled force.

  “Still manageable.”

  But the Tower took that as provocation.

  At that moment, the walkway vanished.

  Not physically—but perceptually.

  The chamber dissolved into a nightmare landscape.

  Below him yawned a massive abyss filled with purple lightning, twisting like serpents through the void.

  Behind him lay a burning city.

  Buildings falling.

  People screaming.

  Thunderlight splitting the sky.

  Flames climbing through the ruins of Valdora.

  A battlefield from the past.

  A battlefield he did not remember.

  A tall figure stood amid the flames—its face obscured, its outline flickering with purple light, its stance like a ghost reaching for him.

  Z-69 stepped forward.

  The bridge was still there.

  The illusion peeled around him, unable to alter the metal’s real vibration.

  Floor 2 had learned his psychology—It didn’t try to trick his sight.

  It tried to trick his memory.

  His empathy.

  His humanity.

  But Z-69’s memories were shattered.

  And his humanity was unstable at best.

  The illusion could not anchor itself to anything.

  He walked straight through Valdora’s screaming skyline.

  The ghostly silhouette extended a hand—as if calling him back.

  Z-69 passed through it without slowing.

  Behind him, the phantom cracked and dissolved.

  Ahead—the narrow walkway remained.

  He was still walking cleanly across a tiny strip of metal suspended over engineered death.

  But the Tower wasn’t finished.

  Twenty meters from the end—

  The walkway convulsed so violently it felt like the room itself was having a seizure.

  The rotation tripled.

  The gravitational shifts accelerated to once every half-second.

  Wind pressure surged into a chaotic whirlwind, roaring like an ancient beast waking up furious.

  The air tore at his clothes.

  His skin blistered under friction.

  His muscles strained to hold shape as joint after joint endured wild changes in torque.

  The cyclones on either side grew tall as towers—violent enough to rip chunks of metal from the edge and devour them.

  Even Z-69’s enhanced perception felt overwhelmed for a moment.

  “Finally.” he whispered.

  “A real attempt.”

  For the first time since entering the Tower, he had to exert himself.

  He took a step—gravity vanished.

  He drifted.

  He stabbed the blade into the walkway.

  Gravity returned at triple force.

  The blade nearly jolted out of his grip.

  He twisted his torso, letting the unnatural pull slide along his spine rather than crush it.

  The walkway spun—first clockwise, then counterclockwise, then at a diagonal.

  Wind hammered at his ribs.

  Z-69’s ankle joint slipped out of place—then snapped back with a sharp metallic click.

  The core in his chest flickered.

  The Hunger stirred.

  A whisper of lightning purred inside his bones.

  Not yet, he commanded silently.

  Not here.

  Not for this.

  He suppressed the rising voltage, though it strained against him like a beast biting at the bars of its cage.

  He bent low—body nearly horizontal—and sprinted.

  Each step carried violent corrections, each movement countered a different invisible force.

  When gravity threw him up—he pulled down.

  When it threw him sideways—he twisted with the momentum.

  When his foot slid—he stabbed the blade into the bridge, using it as a pivot.

  When the wind screamed—he cut through it with the angle of his shoulders.

  He was not running with sight.

  Not with thought.

  He was running with a soldier’s phantom memory—a choreography carved into instinct long before he forgot his own name.

  Ten meters.

  Five.

  Two.

  He jumped.

  Gravity flipped one last time—trying to yank him backward—but he caught the final metal ledge with one hand, the blade embedding beside it.

  The chamber froze.

  Everything stopped.

  The cyclones died, collapsing inward.

  The illusions dissolved.

  Gravity stabilized.

  The walkway ceased rotating.

  The roaring wind evaporated like mist.

  A peaceful silver chamber now extended before him— as if the entire ordeal had been nothing more than a fever dream.

  Overhead, a panel lit up:

  [Floor 2 – Completed.]

  [Evaluation: High-level survival balance.]

  Z-69 rolled his wrist.

  The joints realigned smoothly, electricity settling inside his veins.

  “Annoying.” he said.

  But beneath the annoyance was something else—recognition.

  His body had moved without conscious input.

  Patterns of footwork.

  Counter-rotations.

  Weight-shifts designed for aerial combat and unstable terrain.

  Movements from a life he no longer remembered.

  He exhaled slowly.

  Not relief.

  Restraint.

  The door ahead slid open, revealing warm orange light and a rising wave of heat.

  Floor 3.

  Pressure.

  A trial built to crush bodies—and sanity—and the violet core inside him.

  The core vibrated faintly, like a heartbeat that did not belong to him.

  Z-69 placed a hand on the doorframe.

  He did not hesitate.

  He climbed.

  And the Tower, ancient and hungry, accepted him.
