The Yellow River water was black. Thick. You couldn't see your own hand.
Shen Yangui wore a deep‑dive helmet. The glass was fogged on the inside. His flashlight cut three feet into the water. Beyond that, nothing. Just dark.
He moved along the bottom. Felt rocks. Slippery with moss. Rotten wood that crumbled when he touched it. Broken glass from old bottles.
His fingers touched something soft.
He stopped. Pointed the light.
A body. A woman. Red dress. White face. Eyes half open.
Shen didn't back away. Three years on the job. He had seen hundreds of bodies. Pulled them out of the water. Counted the rings on their fingers. Cut them loose from the fishing nets.
But this one was different.
She was standing up.
Grandpa said: Standing bodies. Don't touch. They're not dead. Not really. They're waiting.
Shen stared at her feet. They weren't touching the bottom. She was floating. But upright. Like someone had nailed her to the water.
He hesitated for one second.
That was all she needed.
The body's hand shot out. Flat on his chest. Pushed.
Shen flew backward. His back hit a rock. Pain shot through him. The air went out of his lungs. His helmet cracked against stone.
He steadied himself. Pulled out his bone hook. The handle was cold. Familiar.
The body floated toward him. Hand reached for his neck.
Shen dodged left. The hook came up. Ripped through the body's chest.
No blood. Just black smoke. Thick. Hot. It smelled like burned hair.
The body didn't stop. The hand came again. Fingers stretched. Too long. Too many joints.
He dodged again. No step back this time. He jammed the hook into the body's throat. Twisted hard.
The head tilted. The body started falling apart. Not breaking. Melting. Turning into black smoke from the edges.
The smoke didn't float away. It rushed at Shen.
He raised his arm to block. The smoke went through his skin. Through his suit. Through his bones. His right palm burned like fire.
Shen bit down. Didn't scream.
The body was gone. Just a red robe sinking to the bottom. It landed in the mud. Folded itself like someone had placed it there.
He turned his hand over.
A mark. An upside‑down triangle. Burned into his skin. Wouldn't wipe off. He tried. Rubbed it with his thumb. Nothing.
Shen stared at it.
Two seconds.
He remembered his father's notebook. "The one chosen by the Nine Doors gets a mark."
He thought it was a story. Old words. Dead words. Now it was in his hand.
He wanted to curse. Didn't.
Scared? A little. Not of dying. Of starting the same way his father did. And never coming back.
Shen made a fist. The triangle burned. Not painful. Just warm. Like a coal under the skin.
He swam up.
---
He broke the surface. Took off the helmet. Breathed deep. The air was cold. Smelled like dead fish and mud.
Looked at his palm again. Still there.
He climbed onto the riverbank. Water dripped off his suit. The triangle mark was hot. Not burning. Just warm. Like something was alive under his skin.
He started walking toward the town.
The streets were empty. Most people stayed inside after dark. Too many things could get you at night. Hollows. Thieves. The mist.
A broken streetlamp flickered. No one fixed it anymore. No one fixed anything.
He passed a boarded‑up shop. The sign said "Wang's Repairs." Wang was dead. Killed by a hollow last year. No one took his place.
He reached his door. It was closed. Good.
He checked the lock. Still there. No scratches.
He unlocked it. Went inside. Turned and locked it again. Dropped the bar across. Listened. Nothing. No footsteps. No breathing.
The room was small. A table. A chair. A bed in the corner. A shelf with a few cans of food. A picture of his father on the wall. Young. Smiling. Holding a fish.
No one else.
He poured a cup of water from the jug. Sat down in the chair.
The chair creaked. Same creak every time.
His hand was still warm.
He looked at the triangle. The lines were sharp. Clean. Like someone had drawn it with a knife.
He thought about his father's notebook. Where was it? In the drawer. He should read it again.
But before he could stand up—
The floor disappeared.
---
No crack. No warning. The dirt floor just wasn't there anymore.
He fell.
Not like jumping. Like being pulled. Down. Fast. The air rushed past his ears. He couldn't see anything. Just black.
He hit something hard. Shoulder first. Pain shot through his arm. He bit down. Didn't yell.
Voices. All around.
"What the—"
"Where am I?"
"Who are you, people?"
Shen pushed himself up. His right hand hurt. The triangle was dark again. Not glowing. Just a black mark on his skin.
He looked around.
A big room. White walls. No windows. One light hanging from the ceiling. It buzzed. Like the old lamps in the town square.
People. Eight of them. Including himself.
A fat man sat on the floor, holding his head. "This isn't real. This isn't real."
A woman in a business suit checked her phone. No signal. She cursed. Threw the phone against the wall. It bounced. Didn't break.
An old man leaned against a wall. Smoking. Calm. His hands didn't shake.
A young kid, maybe nineteen, was shaking. His eyes were wide. Sweat on his forehead.
A tall guy with a neck tattoo punched the wall. It didn't move. He punched again. Nothing.
And in the corner, a woman with short hair held a small knife. Quiet. Not scared. Watching everyone.
The fat man stood up. "Hello? Can anyone tell me where we are?"
No one answered.
The businesswoman pointed at the wall. "Look."
Words appeared. One letter at a time. Like someone was writing from the other side.
"SEVEN DAYS. SEVEN PAPER DOLLS. ON DAY SEVEN, YOU BECOME THE SEVENTH."
The fat man's face went white. "What does that mean?"
The tattoo guy stopped punching. He read the words. His face changed.
"I heard about this," he said. "The Nine Doors. My cousin went in. Never came out."
The old man took a slow drag of his cigarette. "Then we're dead."
"Shut up," the businesswoman said. "There has to be a way out."
She walked to the wall. Pushed it. Nothing. She kicked it. Nothing.
The kid started crying. Soft at first. Then loud.
Shen didn't say anything. He looked at the floor.
Paper dolls. Hundreds of them. White face. Red mouth. Black eyes. All the same.
They all faced the center of the room. Where the people were standing.
The woman with the knife moved next to him. "You see it too?"
Shen nodded.
"The dolls. They're watching us."
"I know."
She held out her hand. "Jiang Xing'er. Medical examiner."
"Shen Yangui. Bone collector."
She raised an eyebrow. "A bone collector? Those still exist?"
"Yeah."
The fat man stumbled over to them. "You two know each other?"
"No."
"Oh." The fat man wiped his forehead. "I'm Ma Tao. I sell fish."
The old man put out his cigarette on the wall. "Might as well do this right. I'm Zhou Decheng. Retired."
The businesswoman tucked her phone away. "Liu Mei. Import export."
The kid sniffled. "Zhang Xiaolei. I'm a student."
The tattoo guy crossed his arms. "Wang Long."
Jiang looked around. "That's everyone. Eight of us."
She pointed at the wall.
"Seven days. Seven dolls. Day seven, the seventh person becomes a doll."
"Then we need to find a way out before day seven," Liu Mei said.
"How?" Wang Long asked. "There's no door."
Shen walked to the wall. Ran his hand over it. Cold. Solid. His fingers felt a small bump.
Then he stopped. One spot was warmer. Just a little. Like a hand had been there.
He pushed.
The wall didn't move. But a crack appeared. Thin. Spidering out from where he pushed.
"The door is not a door," Shen said.
"What's that supposed to mean?" Ma Tao asked.
Shen didn't answer. He pulled out his bone hook. Jammed it into the crack. Leaned on it.
The wall split open.
Behind it was a hallway. Dark. Long. No end in sight. The air from the hallway smelled like dust and old paper.
Wang Long walked over. Grabbed one of the paper dolls. Lifted it. "This is stupid."
He threw it against the wall.
The doll broke. Paper flew everywhere.
Underneath the paper was a bone.
Human bone.
Everyone saw it.
The room went silent. Even the buzzing light seemed quieter.
Zhou put out his second cigarette. "That's not good."
Shen walked to the broken doll. Picked up the bone. Turned it over in his hand. Looked at the joint. The density.
"This was a person."
"How do you know?" Zhang asked, voice shaking.
"Because I've pulled enough bodies out of the water to know a human bone when I see one."
He dropped it. Wiped his hand on his pants.
"The dolls are made of people. The people become dolls."
Liu Mei stepped back. "That's insane."
"Probably. But that's the rule."
Shen looked at the wall again.
"Seven days. Seven dolls. Day seven, you're the seventh."
He turned to face the group.
"Six people die before day seven. The last one becomes a doll."
Ma Tao started crying. Loud. Ugly crying. His whole body shook.
Wang Long grabbed Shen by the shirt. "You don't know that. You're just guessing."
Shen didn't push him off. Didn't flinch. He looked Wang Long in the eyes.
"I've been in places like this before."
"You have?"
"No. My father did. He didn't come back."
He waited a beat.
"So I'm not guessing. I'm telling you what's written on the wall. Read it yourself."
Wang Long let go.
The wall changed again.
"FIRST NIGHT STARTS NOW."
The lights flickered. Once. Twice. The buzzing got louder.
The paper dolls moved.
Not all of them. Just three.
They turned their heads. Slowly. One by one. The necks didn't bend. The whole head turned. Like a doll on a stick.
All looking at Ma Tao.
He stopped crying.
"Why are they looking at me?"
No one answered.
The three dolls floated off the ground. Paper arms reached out.
Ma Tao screamed.
Shen grabbed his bone hook. The handle was warm now. Just like his palm.
He stepped forward.
