Shen had not slept.

He had been walking for two hours before he realized where he was going, and by the time he pushed through the service entrance of the Meridian Hotel, his hands were still shaking a little. The Meridian was the kind of place you walked past without looking at twice. Ironpact kept its seventh floor behind a coded door marked Conference Room B.

Three people were in the corridor when he came through. They went quiet when they saw him.

"Why are you here?" one of them asked.

"The base is gone!" Shen shouted. "I need to talk to C-Crane!"

Nobody said anything after that, but they glanced at each other and took him upstairs.

Six people were in the main room, the morning shift pulling gate rotation updates across two screens. They all looked up when he walked in, and none of them looked back at their screens right away. He had caught his reflection in a shop window on the way over and had not stopped walking.

"What happened to the base?" someone said. "What happened?"

Shen sat down without being invited. "We were attacked."

"By whom? And how many are down?"

He looked at the table for a moment. "I don’t know who did it or how many. But when I left, the building was silent."

Silence.

"What do you mean by that?" said the man nearest the screen with his eyes narrowed.

"I mean, nobody was moving. Nobody was responding." Shen pressed his hands flat on the table. "I walked three corridors before I understood what I was looking at. People were on the floor like whatever happened to them happened before they could do anything about it."

Nobody said anything.

"Could it be one of our rivals?"

"Or an enemy we didn’t know about?"

"No, that isn’t the issue." One of them shook his head before glaring at Shen. "Are you sure... It was just one person and not an entire team?"

Shen paused before furrowing his brows. "I don’t know... All I saw was one person in the building."

He watched their faces. Shen had known them for two years and he recognized the look immediately.

They were suspicious.

"How did you get out?" someone finally asked.

He looked down at the table. "He let me go," Shen said.

Nobody spoke. He held their gaze, waiting for the question he knew was coming.

"He let you go?" someone repeated, carefully.

"Yes."

"Why?"

"I don’t know," Shen admitted. "He just stepped aside and told me to go. So, I did."

All of them raised a brow, but before anyone could respond, the far door opened.

Crane came in without announcing himself and stood at the head of the table. He looked at Shen for a long moment.

"He let you go," Crane said.

"Yes," Shen said.

Crane was silent, holding his chin as he stared at Shen. He shivered under Crane’s gaze, wondering if Crane would hold it against him for running away.

But then, to his shock, Crane shook his head and said. "No."

Shen looked at him.

"He sent you," Crane said. He looked at the table, at the people around it, and then at the door Shen had come through. "He took down everyone he needed to take down and left the exits clear for you. That is a message meant for me."

The room was very quiet.

...

Kai saw the new rotation the moment he approached the first gate.

Different spacing.

Different timing.

The guards were in different places than the night before. Not shuffled around. Replaced entirely, the whole pattern was scrapped and started over. Someone had seen his work and thrown it out.

He walked past the first gate and counted heads. Then the second. Then the third. By the fourth, he had what he needed.They weren’t trying to stop him anymore but instead study him.

It was a smarter play than locking doors.

He had expected them to scramble. They hadn’t.

The fourth gate fed into a long street that opened toward the edge of their territory. He had found it the night before, a gap they hadn’t gotten to yet. He turned toward it and kept his pace even, nothing urgent, just a man with somewhere to be.

[D-Rank Dungeon found.]

[D-Rank Dungeon: Beast Cavern.]

[Recommended Level: 15.]

And he stepped through it.

[D-Rank Dungeon: Active.]

The dungeon was tighter than a D-rank should have been. Lower ceilings and compressed corridors, the kind of layout that reduced lateral movement and made positioning a more significant factor than it would have been in open ground.

The first wave came faster than it should have.

[Serrated Hound]

[Level 16.]

It was lean, covered in dark overlapping scales with a jaw that opened too wide, built for speed over mass.

Kai moved, and the blade arrived, and the first one dropped. He turned, already reading the next angle.

It wasn’t there.

The hit came from the side. Not monsters. People, spread along the corridor wall in the specific stillness of something that had been waiting for exactly this moment, for him to finish the first wave before it showed itself.

They had planned for his movement.

"So they changed it," Kai said.

Nobody answered.

Six of them spread across the corridor in pairs, the spacing deliberate enough that moving away from one position brought him closer to another. The nearest was twelve feet out. The one farthest back was already raising her hand toward him.

Then they rushed towards him with long-range abilities, blasting through the corridor from multiple concealed positions. Kai moved instinctively, but felt the distortion scatter as it pulled toward too many targets at once instead of settling on optimal solutions.

A plasma bolt caught his shoulder, spinning him sideways.

They almost had him.

Another energy blast grazed his ribs before he’d finished recovering from the first impact.

Neither hit was serious.

That wasn’t the problem.

They weren’t trying to finish him quickly. They were trying to keep him busy, for what? He didn’t know, but he had no desire to find out.

He called the Guard emulation as he took out a steel shield from his inventory.

[Class Emulation: Guard - Partial.]

Blue light enveloped the shield as he raised it defensively. Abilities crashed against the construct in rapid succession. The barrier cracked under impact. Another strike shattered it completely.

’Good.’ He thought. ’That meant they were serious now.’

Kai summoned a replacement immediately.

And he quickly reached the center corridor with both ends on his right.

Then the monsters surged from ahead, not at their natural pace but faster, pushed forward by something. The corridor compressed further as a section of terrain to his right gave way, not randomly but timed to the surge, forcing him left into a prepared angle of attack.

The trap closed.

He exhaled once.

They had built it carefully. The dungeon layout, the Ironpact positions, the way the terrain had been collapsing in sequence, all of it feeding into the next thing. Every move he made opened a new problem. There was no clean answer because they had made sure there wouldn’t be one.

He stood in the middle of it and felt that settle. A pressure he hasn’t felt in a very long time, one that gave him a feeling of nostalgia.

Good.

He almost missed this kind of pressure.

No distortions, no chains, nothing to work with except the gap between one problem and the next, and the question of whether he could find a direction inside it rather than a way around it.

A smaller room with harder constraints but the same question.

He had always found it.

Six Ironpact members still in play, monsters cycling from the front, two sections of terrain already unstable. He stopped looking for the clean path and started moving with the disruption instead.

When the next barrage came, he stepped into it. The blade redirected, angling a charging Hound sideways into the nearest Ironpact member’s path. The member’s eyes widened before a Hound latched its jaws on him and pushed him down.

It opened a gap, and Kai was already through it.

A strike came at his left side.

Kai shifted with it.

The strike passed, and then stepped into the space the deflection left him. Putting him behind the next member’s guard before that member had finished processing where the last exchange had ended.

The blade arrived.

It was too late for them.

The formation bent as two fell.

The other four still moving, none of them in the position they had started in. The corridor they had shaped into a trap was now reshaping itself around something they hadn’t planned for. One of them finally stopped aiming at Kai and started trying to escape.

He locked onto this before dropping down, smashing into the runner and then dragged him away after turning invisible. The exchange lasted barely two seconds, shocking the other two while the last one panicked.

But they couldn’t do anything else but continue moving.

Three left.

None of them wanted to be next.

The three of them tried to find their way back to positions that didn’t exist anymore, in a space that had stopped working for them and started working against them. He kept moving as the terrain collapsed again beneath one of them. They fell, and a creature followed them down into the gap.

And were gone.

Another path collapsed.

Two left, both of them pulling back toward the far wall, the gap between them narrowing as the terrain kept failing.

Kai did not look at it and did not slow down.

The distortion moved ahead of him, turning each of their moves into the setup for the next thing it did to them.

One of the Ironpact members pulled back toward the wall. "How is he doing all of this—"

Nobody answered because Kai was already on him, already past, already setting off the chain reaction.

The formation broke.

They tried to reset, and the dungeon did not cooperate because the terrain that had been their tool had become something they could no longer predict.

The floor buckled in the spot where two members attempted to pin him, but their trapdoor opened half a meter early, and they both went tumbling into the sinkhole.

A minute ago, staying close had been an advantage.

Not anymore.

One went down from the blade. The other went down from the terrain, giving way under the impact of a creature that had been heading for Kai and ended up heading for the gap that opened when the other member fell.

In the span of seconds, the corridor returned to a tense, echoing quiet. Kai stood among the ruins and checked his body. The fresh wound at his bicep was an open complaint, but not a protest he needed to hear twice. He pressed gloved fingers to it, waited three seconds, and moved on.

He looked at the corridor behind him.

They had built the best version of this trap he had seen yet. Better angles than the dungeon. Better coordination. Terrain collapse timed specifically, the dungeon itself used as a tool. They had studied what failed last time and fixed it.

And it still hadn’t been enough. He thought about what that meant for the version they would build next. They’d look at this, find what had failed, and change it.

They would keep adapting which he’d already decided was more interesting than an enemy that didn’t. Kai rolled his shoulder once, felt the specific conversation his body was having about the morning’s damage, and memorized it alongside everything else.

It was a pity he didn’t record this. If he could release the footage publicly, the effect it would have on the city would be massive. Not just on the Ironpact but also the way people saw him.

He turned toward the exit.

Regardless, he will make sure the Ironpact wouldn’t get another attempt on him.
