[F-Rank Gate Detected.]

The gate was visible from two blocks away. It sat in the middle of what had been a normal intersection, a fracture in the air roughly three meters tall that didn’t glow. It pressed outward like the air around it was being pushed from the other side. He’d already bought an iron sword from the seller and ignored the crowd.

With no hesitation.

He stepped right inside of it.

The change in scenery hit him immediately.

The air inside the dungeon was colder with uneven ground and little amount of light. Everything felt compressed, like the space was slightly smaller than it appeared.

His status screen updated automatically.

[F-Rank Dungeon: Active.]

Kai walked forward with his hand gripping the sword before freezing when he heard noise. It rushed through the dark and quickly covered the distance between them in about a second and a half. And then out of the darkness came a massive humanoid rat with long claws.

[Feral Stalker]

[Level 1.]

Kai moved forward instead of back.

The Feral Stalker rushed him, swiping toward his face. He evaded to the side and slashed but the monster had already shifted.

The blade didn’t follow his arm.

It paused for half a second, found a new angle on its own, and arrived at the point the Stalker had moved to. The sword passed through the creature before Kai had finished processing that his initial strike had missed.

The Stalker dropped.

Kai stood still.

His attack should have missed. Instead the blade had corrected itself mid-swing and found the target without him directing it there.

Too precise.

’Is this the passive?’ He hadn’t chosen that angle. The blade had.

’It didn’t swing,’ he thought. ’It arrived.’

Then the system responded.

[Condition Met: First Engagement.]

[Recalculation Initiated.] [Distortion Applied.]

[Drop Quality: Optimized.]

[Amplification Complete.]

Kai looked at the drops below him and stayed still.

The results were wrong.

Not broken or glitched, just significantly better than what a level one creature in an F-rank dungeon should have produced. He crouched beside the creature and looked at what it had dropped. An uncommon armor with very good stats that would easily make him twice as tough.

Drop Quality: Optimized.

The notification hadn’t been about the reward calculation. It had been about this, the physical thing in his hand. The distortion hadn’t waited for the system to assign a value to the drop and then inflated that value.

It changed the drop itself.

’It finds the best version of each result,’ he thought, ’and pushes toward it. The strike, the drop, the reward. It gives the best result every time like I have perfect luck.’

He stood up, put on the iron armor, and kept moving.

The next passage opened into a wider space with uneven ground and two more stalkers moving in the shadows near the far wall. Kai approached at the same pace and let them come to him rather than pressing forward, watching the way they moved and noting the angle each one was tracking him from.

The first one reached him and he struck it. But then he felt the sword pulling him towards another direction and he unconsciously tried to pull it back.

The sword was delayed.

In that half-second the Stalker finished its approach and the claw caught him across the chest, making him groan in pain and blood to leak out.

He quickly rushed back but then another claw arrived and scratched his shirt. Pain exploded across Kai’s chest. For a second, panic hit him as blood flowed out of his chest and he hit the wall.

If he died here...

Mina and Leo would lose everything.

The next one came rushing at him, making him sidestep and this time relax his arms as the sword swung.

And a severed head spun through the area.

[Recalculation Initiated.] [Distortion Applied.]

[Drop Quality: Optimized.]

[Amplification Complete.]

The numbers were different from the first kill. Still better than they should have been, but this time he saw a beast core and other items like common weapons the man outside the gate was selling. He killed the first stalker that injured him and checked again and the number of drops increased.

The pattern was clear by the sixth kill.

It wasn’t just better but also stacked. The more monsters he killed the more the rewards stacked.

The sixth stalker came from his blind side, faster than the others, angled at his unguarded left. He hadn’t seen it in time to reposition.

The blade moved anyway.

The blade, shifting angle in the half-second before the stalker even finished its approach. It dropped before Kai had finished turning toward it.

He stood still.

He hadn’t done that. The distortion hadn’t corrected his strike this time but instead moved first. Read the approach before he had, acted on what he hadn’t processed yet. Not optimization but operating ahead of him.

"It gets better the longer it runs," he said quietly.

It wasn’t about strength but how long he could keep it going.

...

Kai pushed open the boss room and stepped inside to see rays of light shining through the ceiling.

And then he saw it, the boss.

[Feral King]

[ Level 5.]

The rat was massive, easily standing above Kai with brown fur, sharp claws, and looking down at him with crimson eyes.

It rushed him, growling.

Kai shifted his stance and brought the blade up and the strike landed on the creature’s shoulder rather than where he’d aimed for.

The same mid-course correction as before. Not where he’d intended but where the distortion had decided the strike should land.

The Feral King staggered.

From a glancing shoulder strike, not from damage alone but from the distortion finding the best spot for the stagger.

It recovered faster than something that size should have. The counter came immediately, a sweeping backhand aimed at Kai’s head while he was still inside the strike’s momentum, no time to step back before it arrived.

The blade pulled his arm down.

Not a conscious deflection but the distortion reading the incoming arc. Then finding the one angle that redirected the momentum sideways rather than absorbing it. Feral King’s arm was pushed towards the side, making it stumble forward and opening itself for an attack.

Kai didn’t have time to process what happened and the next strike landed on the exposed creature’s stomach. The result was larger than the shoulder hit and the Feral King roared out. He pressed the same gap twice more before the Feral King’s legs gave out under it.

The dungeon went quiet.

[+3 Stats]

Kai stopped.

...That wasn’t right.

That drop shouldn’t exist in an F-rank dungeon. A larger core, a steel sword, steel armor and boss-tier loot, optimized on top of that. He could already imagine estimated credit value when he sells all of this.

An F-rank clear shouldn’t produce such a large amount of very good items. It did.

He swapped his iron sword for the new steel one and then put on steel armor before standing. One strike for most of them. A handful for the boss. He stepped back through the gate, the noise of the city rushing in around him.

A few people nearby noticed him as the gate behind began collapsing.

A phone clattered against the pavement in front of him.

"He cleared it already?"

"Solo?"

A beat of silence, longer than the others.

"...That fast?"

"...No, that’s not possible."

Kai moved past them at the same pace he’d held all morning. He was already thinking about the trading hub and what the optimized drops were going to look like when the clerk ran the scanner.

He was also thinking about the ceiling.

The distortion had been running on basic technique against low-level creatures in a single F-rank dungeon and produced this. He hadn’t even started pushing it yet. He hadn’t even understood the mechanic fully until halfway through the run.

If this was the baseline, then what happened when he stopped holding back? He turned the corner toward the trading hub, tomorrow was already taking shape in the back of his mind.
