The archway from the Fifth Floor didn’t lead to a staircase or a corridor. It led to the absence of the concept of ‘Up’.

  I stepped through the shimmering veil, and my stomach lurched violently as my inner ear gave up the fight entirely. I wasn’t falling, but I wasn’t standing either. I was drifting in a heavy, cold vacuum.

  The sixth challenge was a masterclass in kinetic despair.

  The environment was a colossal sphere of eternal twilight, lit only by the bruising purple friction of rocks grinding against each other in the distance. In the center of this void hung a singular, massive singularity — a point of darkness so dense and absolute it pulled not just matter, but light and sound from the air around it.

  Orbiting this black heart was a chaotic ring of debris: thousands of floating rock platforms ranging from the size of a shield to the size of a city block. They moved in intersecting, violent orbits, colliding with the force of meteor impacts.

  But there was no noise. The Singularity ate the soundwaves before they could travel. I watched a slab of granite the size of Bastion’s main hall smash into a cluster of diamond asteroids, pulverizing into dust in absolute, terrifying silence.

  The objective was simple: Reach the event horizon without becoming dust.

  Gravity here wasn’t just heavy; it was erratic and weaponized. One second, I was weightless, floating in zero gravity; the next, a localized wave of a force two hundred times earth’s gravity would wash over a section, invisible and lethal.

  “Navigation by intuition,” I thought, the words trapped in my throat. I anchored my boots to the first platform with mana, feeling the stone beneath me trembling from the tidal stress.

  I used my Perception to watch the debris field. The rocks weren’t random; they were caught in gravitational slipstreams.

  I jumped.

  Mid-air, between safety and the void, a wave of force hit me. It felt like being slapped by a giant hand. My trajectory warped. I was pulled sideways, accelerating rapidly toward a jagged asteroid spinning like a buzz saw.

  I reacted instinctively. I triggered my [Domain], not as an attack, but as an engine. I fired a micro-burst of [Ashen Flame] from my left palm, using the thermal expansion to shove me out of the kill-path.

  A test of Adaptation, I realized, sweating in the cold vacuum. Gravity is the wind that I had to sail.

  This level was less about power and more about flow. I spent three days hopping between asteroids, timing my leaps to the rhythmic, mute thumping of the black hole in the center. I had to calculate vectors on the fly, dodging rocks that moved faster than sound. I knew I could do it with enough practice, so I used the learning opportunity, refusing to use [Void Walk].

  But the emptiness was not empty. As I neared the inner ring, shadows detached themselves from the rocks.

  Gravity Wraiths.

  They were Tier 6 constructs made of condensed matter and hunger. They looked like human figures drawn entirely in Dark Matter, vibrating with an instability that made my teeth ache even in the silence.

  A Wraith lunged. It didn’t swipe with a claw; it extended a limb and pointed.

  Suddenly, my own armor tried to crush my ribs. I gasped, blood rushing to my head as the localized gravity focused entirely on my sternum.

  I used a method of combining the mana authority of my [Domain] with my [Veil] to phase out my physical weight. By removing my mass from reality, the Wraith’s gravitational grip slipped off. I stepped through the vacuum, invisible and untethered, and materialized directly behind the entity.

  It spun, trying to lock onto my mass again.

  “Too slow,” I whispered.

  I placed my palm on its back. Instead of burning it, I reversed the polarity of my mana. I pushed out with a sphere of pure repulsive force. The Wraith, a being built entirely out of Dark Matter, shattered under the sudden, violent push. It dissolved into violet dust that was sucked into the black hole.

  It was a grueling, three-dimensional melee in zero-G. I fought swarms of them, managing my trajectory while dissecting enemies that could crush bone just by looking at it. By the time I reached the event horizon — the exit was the hole itself — I was covered in bruises deep in the marrow.

  “A test of Will, and Faith,” I thought.

  I tucked my limbs and dove into the dark.

  I emerged from the darkness onto a floor made of living light.

  Level seven was the opposite of the emptiness of the sixth; it was a sensory overload.

  The room was infinite. The walls, ceiling, and floor were composed of hexagonal panels made of shifting, colored glass. They constantly rearranged themselves in a maddened Fibonacci sequence, clicking and whirring as they shifted positions.

  Each color represented a fundamental law turned up to eleven.

  Red panels burned with the heat of a star. Blue panels halted time entirely. Green panels accelerated entropy, aging anything that touched them into dust in seconds.

  And they were moving.

  This was the first time I felt genuinely slow. My speed meant nothing if the floor I stepped on decided to freeze me in stasis for a century. I had to stop relying on reflexes and start relying on reading.

  I relaxed into a meditative stance, and focused on maximizing the output of my [Void Perception]. The chaotic swirls of color resolved into data streams. The Red panels vibrated with excited atoms. The Blue panels hummed with stillness.

  “Another pattern,” I realized after watching the rotation for ten hours from the safety of the entryway. The dungeon wasn’t random; it was a very complicated math equation.

  I moved. I stepped onto a yellow panel that decreased gravity, used the momentum to vault over a red kill-zone, and landed on a blue tile just as it shifted to harmless grey.

  Unauthorized usage: this narrative is on Amazon without the author's consent. Report any sightings.

  But the Dungeon wasn’t content with just puzzles.

  Mirror-Doppelgangers stalked the shifting tiles.

  They rose from the floor — exact duplicates of me made of hard light. They mimicked my movements with a fatal half a millisecond delay. If I swung my sword, the reflection swung a heartbeat later.

  One lunged at me. I parried, but the delay threw me off. Its blade passed through my guard a second after I blocked, grazing my arm. It cut deep, burning with cold light.

  Combat here was a chess match played at sprinting speeds. I couldn’t just overpower them; they matched my strength. I had to exist outside their control.

  I feinted a charge onto a blue panel. I paused my own Time for a microsecond using my own [Domain]’s authority. The Mirror copied me, freezing in place.

  Just as it froze, the panel beneath it shifted to Green.

  The Doppelganger screamed — a sound of digital corruption — as the entropy tile aged it a thousand years in a second. It rusted, crumbled, and blew away as dust.

  I fought my way across the Kaleidoscope, using the environment as my weapon. I lured golems made of Time glass onto high-gravity tiles, watching them shatter under their own weight.

  It took me a week of sleepless, constant motion to reach the exit. My mind felt flayed, forced to process tactical geometry at a speed that blurred the line between thought and instinct.

  Then came the white.

  I stepped through the final Mirror, and reality ended.

  There were no walls. No floor. No sky. Just an endless, infinite white expanse.

  And in the distance, a structure that made my eyes bleed to look at.

  It was a fortress that folded in on itself. Escher-geometry on a divine scale. Staircases connected to the underside of the floor they started on. Towers spiraled inward to become tunnels. Angles that looked like ninety degrees acted as if they were one hundred and eighty. Straight lines curved.

  “Level 8,” I rasped, the sheer impossibility of the sight pressing against my sanity.

  A notification flickered, harder to read against the blinding white.

  [Trial 8: The Knot]

  [Distance is a lie. Direction is a suggestion.]

  [To go forward, you must go deeper.]

  The silence here was aggressive. It chewed at my thoughts.

  I took a step toward the fortress.

  I intended to move forward. Instead, I moved up. I walked five feet and found myself standing on what I thought was the ceiling, looking down at where I started.

  “Space is knotted,” I realized, touching the air. It felt thick, curdled like sour milk. The causal strings of the Lattice were tied in impossible loops here.

  This wasn’t a puzzle I could walk through. I had to untie it.

  I sat down in the white expanse. I summoned my [Mana Authority], not as a weapon, but as an instrument. I reached out into the tangled mess of the Dungeon’s code.

  I grabbed a string that defined “Forward” and pulled. The landscape shimmered. A door appeared where a wall had been.

  This level wasn’t combat. It was surgery.

  I spent two weeks here.

  I navigated the impossible fortress room by room, unknotting space to create a path. It was grueling. Sometimes, pulling a string would cause the room to rotate, dumping me onto a wall. Other times, it would shrink the room until I was crushed against the ceiling.

  I used a Glimpse to test if I could simply [Void Walk] to rush through and find the quickest path. The differences between the Void and Space Affinities became a lot more apparent. It was a bit slower of a [Walk] through the Lattice, and a little more Mana draining, but it still completely bypassed the Challenge. I wondered if the System would reduce the rewards for using such a method.

  I released my vision, opting to try to clear the Floor without the Void. Which would also give my Glimpse enough time to be ready by the time I entered the ninth.

  I stood on a twisted bridge that looped back on itself infinitely. And blocking the path was the Guardian.

  It was a Star-Spawn.

  A massive, multi-limbed entity made of Space-stuff and nebula gas, pulsating with an aura that felt shockingly familiar. It had no face, only a swirling vortex of blue light where a head should be. Its limbs ended in talons that dripped liquid darkness.

  “Tier 7,” I choked out, my perception recoiling from the sheer density of the creature’s soul. “A Tier 7 monster. In a local Dungeon…?”

  This thing rivaled the ambient pressure of the Kyorian ship.

  The Star-Spawn didn’t roar; it erased.

  It swiped a claw. A chunk of the bridge under my feet simply vanished.

  Space was Deleted.

  I fell into the white nothingness.

  I activated [Void Walk].

  I didn’t step out of reality; I stepped deeper into it. I used the Void to swim through the emptiness, treating the nothingness as a solid medium.

  I materialized on the creature’s flank and struck. My Ashen Sword passed through it like smoke.

  It has no mass, I analyzed, dodging an erasure-beam that wiped a spiraling tower from existence. It is purely conceptual. It exists partially in the Void.

  The fight was a nightmare. I couldn’t touch it, but every time it touched reality, something ceased to exist. I was forced to burn mana just to keep my own body coherent against its erasure field.

  If you pull the Void into reality, I thought, my mind racing, it has to obey laws.

  I stopped fighting. I stopped dodging.

  I engaged [Apex Mana Authority].

  I reached out with my Soul, ignoring the panic of falling forever into limbo. I grabbed the space the Star-Spawn occupied. I didn’t try to crush it. I tried to fill it.

  I poured almost a quarter of my entire mana pool into that singular point.

  “I deny your vacuum!” I roared, the words dead in the silent air.

  I flooded the Star-Spawn with pure, unadulterated matter. Using my [Mana Authority] I materialized many different types of affinities directly inside its core. I forced existence into the Void of its body.

  The Star-Spawn shrieked — a sound of tearing reality. It couldn’t handle being real. Its conceptual immunity shattered as I forced mass into its spectral form. It writhed, the nebula gas solidifying into obsidian glass.

  It froze, trapped in a moment of agonizing transition.

  Then, gravity — which I had just reintroduced to its equation — took hold.

  The statue fell. It shattered on the twisted architecture below, releasing a tidal wave of silver essence.

  I fell to the floor, gasping. My nose bled freely. My mana core emptied, slowly refilling from the emptiness.

  It felt like the System was pushing me towards using the Void.

  I felt... stretched. My perception of space had been pulled apart and stitched back together so many times I wasn’t sure if I was seeing reality or the wireframe underneath it.

  I looked at my hand. I flicked my wrist, and space rippled. I didn’t cast a spell. I just willed the air to fold, and it did. A tiny pocket dimension opened and closed in my palm.

  “I learned the trick,” I whispered, awestruck. “I can tie the knot now.”

  I stood up. I was tired, mentally flayed, but sharper than I had ever been.

  The door to the final challenge loomed ahead. It was covered in runes that hurt to look at. A warning.

  My Glimpse was up. I had barely used any of my consumables. I was ready.

  I walked to the door. It was cold to the touch.

  I pushed it open.

  I didn’t see a room. I saw the edge of a universe.

  And I stepped through.
