The Tower opened around him.
A stone room. Bare walls. A single staircase rising at the far end. The air was cool but still — no wind, no draft. The ceiling lit by a soft sourceless illumination that did not flicker.
Qalish stood for a moment and read the room.
Floor One. The Tower has given me a starting space and a stairway out. The space exists for the fight.
The spawn began.
Three small monsters faded into existence along the far wall. They moved with the deliberate clarity of something the Tower had drawn from a manual and placed at exactly the position it had been instructed to.
A Fang-Tailed Beast at Lv.1 — narrow wolfish frame, a long spiked tail that lashed once against the floor as it landed. A Crimson Cub at Lv.1 — small, fire-touched, a faint heat haze rising off its back. A Phantom Spider at Lv.2 — six legs, body half-blurred at the edges, the kind of monster the eye had to commit to in order to track.
Foxy stirred at his side, ready.
He cued her back.
She read the cue, stepped behind him, and settled. The five tails lowered, the spirit-fire halo dimming to a low simmer.
He cued Null forward.
Null slid out across the floor — heavier than he had been the day before, the black scales catching the Tower's ambient light in slow hard glints. The Aegis plating along his flanks shifted as he moved. He stopped halfway between Qalish and the spawn, lowered his head.
Twenty-four hours inside. Floor seventy is six hours of real climbing. The remaining eighteen are mine. Use them.
Null has been an Aegis Wyrm for fifteen days. Fourteen against Emberglen monsters. None against an opponent the system gave me at exactly the level I needed. The Tower will give me that. Cheap. Repeatable.
We climb slow. We test everything. When I have what I need, we climb fast.
The Fang-Tailed Beast charged first.
Null held. The Aegis Lock seams flashed. The beast was thrown back along its own vector, hit the far wall, did not get up.
Qalish watched.
Roughly half the strike absorbed, half thrown back. The skill description had said it scales with incoming force — the harder the strike, the stronger the return. At Lv.1 spawn, the rebound is small. Against a stronger opponent the percentage will climb.
The Crimson Cub came in a wider angle, claws dragging heat across the stone. Same result — the rebound flung it sideways into the wall, the small body did not rise.
The Phantom Spider was the cleverest of the three. It came from above, leaping over the angle where the rebound would have caught it, body half-dissolved into shadow on the descent. Null lifted his head — Ironbite. The bite caught the spider mid-air, locked into the structural seam where its forelimb met its body, and the reflection pulse went through.
The spider fell in two pieces.
Qalish blinked.
Two pieces.
He had not seen Ironbite cut a monster in half before. At Emberglen, the bite had crushed and held — locking onto seams, breaking joints, occasionally tearing a limb off a smaller target. Never cleaving.
The Tower spawn is paper-thin compared to forest monsters. It's letting me see what the skill actually does when there isn't enough mass to absorb the pulse.
Useful information. Not useful for the rest of Floor One.
The staircase at the back of the room hummed faintly. Floor cleared.
He walked forward, Null beside him, Foxy still behind. Up the stairs.
Floor Two was the same room scaled half a step harder. Floor Three the same again. Floor Four. Floor Five.
The pattern settled within the first hour.
Null held the front. Aegis Lock seams flashed each time a monster committed; each time, the monster came back along its own vector and did not get up. When something came in too high or too clever for the rebound, Ironbite caught it. Foxy stayed behind, watching, recording the angles, learning the seams of Null's plating from the back the way Qalish had drilled her in Emberglen.
She was building the map of him.
That was the point.
Floor Ten was a boss room.
Wider than the prior nine — larger ceiling, deeper floor, stone polished where the earlier floors had been rough. The Tower had built him a Floor ten arena to match the Floor ten scale.
The boss spawned. A Ridgeback Maul at Lv.5 — six-legged, low to the ground, heavy ridge of bone running from its skull down its spine, jaws built for crushing rather than tearing.
Null already had Aegis Lock active.
Qalish did not call a move. He let Null take the boss alone — final pure-tank test before he changed mode.
The boss charged. Null held. The seams flashed. The boss was thrown back along its own vector.
The boss got up.
Null waited.
The boss charged again, lower this time, angling for the underside of Null's body where the Aegis plating had less coverage. Null adjusted his stance — one of the things Qalish had drilled in Emberglen — and the seams flashed at a different angle along the flank rather than the chest.
The Ridgeback flew sideways. Hit the wall. Did not get up.
Null exhaled. Stonehide settled.
[ Floor 10 cleared.
Boss : Lv.5 Beast — Ridgeback Maul.
Solo clear : Null. ]
Qalish stood, walked over, and ran a hand along Null's flank. The plating was warm under his palm, the seams already cooling. No chips. No cracks. Not so much as a scrape.
He had counted twelve Aegis Lock cycles during the fight. Twelve solid impacts. Null had taken none of them through the plating.
The skill description said passive damage reduction. It did not say this. He is not taking damage at this rank gap. Not really.
That changes when the spawn climbs to his level. But for now — for the next thirty floors — he is the wall.
He sat against the boss room wall. Drank water. Foxy came forward, lay against his thigh briefly, accepted a touch along her flank, and stood again.
Floor ten in just over an hour. Six minutes per floor. Slow.
Slow is correct.
Stairs up.
Floor eleven through Floor twenty was where he widened the test.
He brought Foxy forward. Not to lead. To pair.
The two of them had spent ten days in Emberglen building this — Foxy on the flank, Null at the front, Stormcleft tipping into Aegis Lock counter-rebound. The Tower was the first place he could run that pattern at exactly the level it had been built for.
Floor eleven spawn climbed half a step. Floor twelve another half. The Tower's scaling was deliberate — three floors per monster level, give or take, the curve gentle enough that Qalish could feel each adjustment without being forced past it.
He called the openings. Foxy opened. He called the closes. Null closed. Each floor took eight to ten minutes — not because the spawn demanded it, but because Qalish was deliberately holding pace, watching how each fight resolved, looking for any seam in the pattern that needed adjustment.
He found none.
Floor fourteen. Floor fifteen.
By Floor fifteen, the calls had become shorter. Open. Close. Hold. Cleave. The pair had heard the same instructions enough times across enough drilled hours to read the shape of the next one before it finished landing.
Floor sixteen. Floor seventeen. Floor eighteen. Floor nineteen.
The pattern works at this level. Foxy can hold rhythm against Lv.7 spawn for as long as I let her. Null does not break.
Floor twenty boss room.
The boss was Lv.8. A Twin-Headed Vex — sinuous, fast across the floor, the kind of monster the Tower had picked specifically against Null's plating. The two heads moved independently, looking for the seam gaps, trying to angle around Aegis Lock rather than into it.
It worked for about four seconds.
Foxy — left head. Null — angle right.
Foxy was there before he finished the call. Stormcleft caught the left head as it lunged for the underside; the right head whipped around and Null had already shifted with the call, locking the strike, the seams flashing along the flank where the plating was thickest by design. The serpent body went rigid for the half-second the rebound took to resolve.
Foxy — centre.
Stormcleft cleaved the centre mass. Shadow Bite chained behind it.
The Vex fell in three pieces.
[ Floor 20 cleared.
Boss : Lv.8 Twin-Headed Vex. ]
Qalish read it.
Four seconds. Skills hold. Mana cost is low.
Stairs up.
He did not take them.
He sat down against the wall of the boss room.
Foxy came over and lay against his thigh. Null settled at his other side, the heavy black coils warm against his leg. Both monsters were breathing easily. Neither one anywhere near a limit.
He pulled out his pack. Drank water. Tore a piece of bread and ate half of it. Tossed the other half toward Null, who caught it without looking and swallowed it whole. (He had developed a fondness for bread, of all things, during the Emberglen weeks. Qalish had not asked why.)
He sat for perhaps a full minute.
The Tower's ambient light did not change. The walls did not move. Phased instances did not bleed sound; phased instances did not bleed presence. He was alone in the floor with his two monsters.
Two hours. Floor twenty.
Null has the pattern. Foxy has the rhythm. Both monsters at full HP. Mana barely touched.
I have what I came down for.
A panel opened on its own.
[ External Detection.
System-class material identified.
Source : Tower of Trial. Higher floor.
Exact floor : unknown.
Acquire. ]
Qalish read it twice.
The last word sat at the bottom of the panel by itself. Not "recommended." Not "available." Acquire.
The System rarely gave instructions. It described, it offered, it logged. Across two years of carrying it, he could count on one hand the times it had used the imperative.
It wants this.
Whatever it is — the System wants it.
He sat with that for a moment.
The System had only ever flagged one upgrade-class material for him before — the Unknown Stone, which had taken the System from Lv.1 to Lv.2 and unlocked the Shop function itself. Every Shop tier upgrade since then had been paid in MP. The System Level itself had not changed since.
If there was a material in the Tower that could move the System level itself — only the second time in his life that had been possible — then the climb was no longer about floor seventy.
He was climbing toward a signature.
Higher floor. Could be sixty. Could be eighty. Could be ninety-nine.
Doesn't matter. Up.
He closed the panel.
He had been climbing slowly for two hours.
That's enough training.
He stood.
Foxy and Null stood with him.
He walked to the staircase, did not pause at the bottom, did not look back at the boss room.
He took the stairs.
Now we go.
