The weak climbers were already halfway into the side path when Jaehyuk saw the blood on the stone.
Not fresh. Not old. A smear dragged by a boot. Someone had already tested the route and lived just long enough to hate it.
"Stop."
The man at the front of the group flinched. Two women behind him looked up too fast, like prey hearing a branch crack.
The corridor around them slanted down into a branching cavern system. Floor 5 was built like a throat. Narrow ledges. Split stairways. Blind corners that swallowed sound and spat it back wrong.
And Vanguard had taken the mouth.
White coats. Ten, maybe twelve of them. More on the upper ledge. They were spread across the chokepoints with the calm of people rearranging a warehouse.
One of them pointed with the tip of his blade. "Main route is restricted. This way."
Restricted. Nice word.
Jaehyuk looked at the side path. He heard it before he saw it. Wet clicking. The stink of mineral rot. Air too still.
A dead route.
Somin grabbed his sleeve. Her fingers were damp. Not from fear. From the healer's ointment she always kept on her wrists. Bitter herbs and something metallic.
"Jaehyuk," she said. Fast. Too fast. "That path is bad. I mean, really bad. I can smell it from here, and I don't have a good nose, so that's saying something."
"I know."
"You know a lot of bad things."
"Occupational hazard."
The Vanguard scout on the upper ledge turned his head.
Not at the group. At Jaehyuk.
Young. Clean face. White coat. The kind of smile people used when they wanted you to think the knife was a kindness.
His eyes narrowed. A fraction. Recognition, or close enough to it to be annoying.
Someone who remembers.
Jaehyuk felt the Tower shift under his feet.
Not physically. Not enough to see. The corridor just... tightened. A faint pressure in the air. The stone under his boots seemed to lean toward him, listening.
Interesting.
One of the weak climbers, a boy with a cracked shield and dust in his hair, took a step toward the side path again. A Vanguard hand snapped out and shoved him by the shoulder.
"Move," the enforcer said. "Unless you want to waste the main route."
Waste.
There it was.
Jaehyuk had heard that word before. In a different corridor. Different floor. Different year.
Dohyun's voice in a room full of people pretending not to hear the screaming from the other side of the door.
Route optimization.
That was what he called it the first time.
Jaehyuk stared at the white coats. White shirts too clean for the floor. Black boots. Black gloves. Black teeth when they smiled.
Dohyun had learned early that if you fed weaker climbers to the floor first, the monsters would chase them, not you. If a few people died on the side path, the main team got their safe clear and a prettier report.
Acceptable losses.
The weak always got described like weather. Unfortunate. Necessary. Efficient.
Jaehyuk stepped off the ledge.
Somin hissed, "What are you doing?"
"Fixing a route."
"That does not sound like a normal thing people do on purpose."
He didn't answer. He was already moving.
The group of climbers saw him first. Three of them. No, four. A woman with a broken spear. A man clutching his left arm. Another girl, breathing through her mouth because the air in the side path tasted wrong. Copper and mildew.
Jaehyuk planted himself between them and the side route.
The Vanguard enforcer started down the stair. Big shoulders. Hard jaw. Mid-level stats, probably around 35 Strength and enough Endurance to make stupid decisions feel brave.
He stopped two steps above Jaehyuk.
"Guild business," he said. "Move aside."
Jaehyuk looked up at him. "No."
The man blinked once. Like he wasn't used to being denied in public.
"You heard me. Move."
"I did."
The enforcer smiled. It did not improve his face.
"Then listen better. Vanguard is controlling the route. These climbers are going to the lower branch. The main route is for registered personnel."
"Registered personnel," Jaehyuk repeated. "That's a new way to say bait."
The weak climbers went still.
Somin's grip tightened on his sleeve. She'd moved closer without meaning to. Anger was making her forget to be careful.
Good. He was about done with careful.
The enforcer's smile faded. "Watch your mouth."
"Or what?" Jaehyuk asked.
A few climbers nearby turned their heads. The corridor had gone quiet in the way crowds do when they smell a fight but want plausible deniability.
The enforcer took another step down. Close enough now that Jaehyuk could smell his cologne under the dungeon stink. Clean cedar. Expensive. Completely useless.
"Name's Nam Geonwoo," he said. "Vanguard enforcement. You interfere with guild routing again, and I break your jaw."
He said it like he was offering a discount.
Jaehyuk nodded once. "That's a lot of words for a man standing on stairs."
Geonwoo's expression hardened. "You think you're funny."
"No."
That landed worse than a joke.
Geonwoo put a hand on the hilt at his hip. Not drawing yet. Just touching it. Showing everyone he could.
"Last warning," he said. "Step away. The weak go where they're told."
One of the women behind Jaehyuk made a small sound. Fear, pain, exhaustion. Her ankle was bleeding through a torn boot. Somin saw it too.
And her face changed.
Not fear. Not nervousness.
Fury.
"They're not livestock," she snapped.
Geonwoo looked past Jaehyuk at her. "Healer, shut up. This isn't your lane."
Somin smiled.
It was awful. Tiny. Sharp enough to cut.
"You smell like spoiled milk," she said.
Jaehyuk almost glanced back at her. Almost.
Geonwoo stared for one beat too long.
That was enough.
Jaehyuk moved.
Not at Geonwoo. Around him.
He grabbed the cracked spear from the woman's hand, turned on his heel, and slammed the butt against the left wall seam.
Stone cracked. Dust burst from the joint in a gritty cough that hit the back of the throat. Behind it, a hidden maintenance groove opened half a handspan wide.
The weak climbers stared.
Geonwoo barked, "What did you just do?"
"Found the floor's actual route."
He shoved the spear point into the seam and levered. The old stone groaned. The hidden groove widened. Enough for a smaller climber to squeeze through.
Air spilled out. Cooler. Dry. It carried pine resin and the faint iron tang of a long-unused passage.
Jaehyuk pointed. "Go. Single file. Don't touch the right wall."
The woman with the bleeding ankle blinked. "But that isn't on the map."
"The map is wrong. Move."
The man with the broken shield started first. Then the girl with the dusty hair. Then the others. Hesitant, then fast when they realized the side path behind them had gone quiet in the worst way.
Clicking.
Deeper now. Hungry.
Geonwoo's hand came off the hilt. His voice dropped. "You don't know what you're doing."
Jaehyuk didn't look at him. He was counting footsteps in the groove, listening to the stone. The floor had shifted around his presence twice already today. It was doing it again, trying to close the passage, like a door annoyed by being used.
"I know exactly what I'm doing."
He kicked the lower seam. Once. Twice.
The maintenance route opened another span.
Geonwoo's face flushed red. "You can't just steal guild-controlled route access."
"Watch me."
That finally brought the blade out.
Half a draw. Steel hissed. Not a full threat, not yet. But enough that the nearby climbers stepped back and the air got thin with anticipation.
Somin moved to Jaehyuk's side. Healing light sparked in her palm, pale and bright. "If you hit him, I will be so mad."
"I noticed."
Geonwoo pointed the sword at Jaehyuk's chest. "You think you can embarrass Vanguard in front of a crowd and walk away?"
Jaehyuk glanced at the people around them. Several were watching now. Not the weak climbers. The ones higher up on the ledge. The ones who'd been pretending not to see the routing funnel.
Good. Let them see.
"Embarrass?" he said. "You were feeding people into a kill lane."
"They would've died either way."
The words landed like spit.
One of the climbers behind him made a choked noise. The woman with the spear looked at Geonwoo like she'd just seen his bones under the skin.
Geonwoo noticed the look and got meaner, like that was how he solved being witnessed.
"Weak people die," he said. "That's the floor. Vanguard just decides where."
Jaehyuk took one step up the stairs.
Geonwoo's sword lifted. Not enough to strike. Enough to warn.
Jaehyuk stopped with the blade close enough to kiss his shirt.
"Try it," he said.
Geonwoo laughed once. Ugly sound. "You want a medal for pretending to be brave?"
"No. I want you to move."
The enforcer's left arm twitched.
Jaehyuk saw the weight shift. Saw the shoulder load. Saw the strike forming before Geonwoo's brain finished approving it.
He didn't flinch.
That was the part that mattered.
The corridor held its own breath. Stone. Sweat. Blood. The copper taste was all over the back of Jaehyuk's tongue now, from the climbers, from the wounded ankle, from the dungeon itself waking up to watch.
Behind him, the hidden passage gave a low grinding sound. The floor was trying to seal it.
Somin clicked her tongue. "This floor is rude."
"Only to people who deserve it," Jaehyuk said.
A laugh went through the crowd. One person. Then another. Small. Nervous. Then meaner.
Geonwoo heard it too.
His jaw flexed. He looked ready to turn the whole stairwell into a problem.
Then he froze.
Not because of Jaehyuk.
Because of the Tower.
A blue notice flashed in the air between them, bright enough to wash the corridor in cold light.
[Healing Skill activated.]
[Targeted recovery in progress.]
Somin had already moved.
She was kneeling beside the bleeding woman, both hands glowing now, jaw set so hard it looked painful. Her voice came out clipped. Sharp. Not rambly. Not nervous.
"Sit still," she told the woman. "If you move, it hurts more, and I already hate this floor enough."
The woman stared at her. "You don't have to do this."
"Yes, I do."
Somin pressed her palm to the wound. Light spilled into torn skin. The bleeding stopped. The woman gasped at the sting, then at the relief.
Somin moved to the man with the arm. Then the girl with the mouth-breathing fever breath. One after another. Fast hands. Fierce face.
Jaehyuk had never seen her look like that.
Not scared. Not apologetic.
Angry enough to heal like a weapon.
Geonwoo watched her work, then looked back at Jaehyuk. "Cute. You found a healer."
"Try not to choke on your own teeth."
"You're still on a guild floor."
"So are you."
That made Geonwoo's nostrils flare.
He took one more step. Just one. The sword came up. Jaehyuk shifted his weight, ready to turn the man's momentum into a bad day.
The crowd tightened around them. Everyone could feel it now. The shape of it. Vanguard wasn't order. It was pressure. A hand around the throat, calling itself guidance.
One climber in the back muttered, "They were sending us down there?"
Another answered, "I saw the monster tracks."
A third voice. "My brother went that way."
No one said anything after that.
Geonwoo glanced over, saw the faces, and understood too late that the room had changed. Not because he had threatened them. Because he had confirmed what they already suspected.
He pointed the sword at Jaehyuk again, but the edge had lost some of its confidence.
"You don't know what you're messing with," he growled.
Jaehyuk looked at him. Long enough to make the silence unpleasant.
"I do," he said.
Then the Tower chimed again.
Not loud. Not dramatic. Worse.
A private notification.
Only for him.
[Tower Notice]
[Vanguard Guild: Target designation - YUN JAEHYUK. Status: Active.]
Jaehyuk read it once.
Then again.
The corridor didn't move. The people didn't move. Geonwoo was still breathing through his nose like an animal with paperwork.
But the name at the bottom of the notice was the one that mattered.
Kang Dohyun.
Formal. Clean. Public.
A watchlist.
And that meant Dohyun wasn't just watching anymore.
He had started counting.
