Mu Chen's transfer badge still smelled like fresh plastic.
He clipped it to his chest and looked at his own photo. The camera had caught his face in the wrong second. His eyes looked too calm, almost blank, like he had nothing to fear. That was not true. It was just safer to look that way.
The hallway lights were white and cold. They did not flicker. They never did. This base was built to look clean, built to feel clean, built to make people forget they were trapped.
A door scanner waited at the end of the corridor. A small red light blinked above it, patient and strict.
Mu Chen set his thumb on the glass.
The machine read his skin, his heat, his print. It took a little too long, like it was thinking about him. He kept his face relaxed. If you looked nervous in places like this, you got watched. If you got watched, you got measured. If you got measured too much, you got owned.
The light turned green.
The door clicked open.
The air on the other side felt different. The base always smelled the same, but this floor had something extra. Not a scent, not a sound. More like pressure. Like the space was holding its breath.
Mu Chen stepped in and let the door shut behind him.
A ready room opened in front of him. Couches, lockers, a big table with screens built into it. A kettle in the corner. A few people in uniform. Some looked up right away.
Their eyes moved over him fast.
Guide, Mu Chen thought.
That label came first. It always did.
Most people tried not to show it, but he could see it in their faces. A guide was help. A guide was risk. A guide was a weakness you had to protect and a tool you had to keep.
A woman in uniform stood near the table. She had short hair and a clean posture and eyes that did not waste time.
She walked toward him.
"Lieutenant Mu Chen?" she asked.
"Yes, ma'am."
"I'm Colonel Luo Wei. Welcome."
Her voice was calm. Her face was calm. That was the worst kind of calm. It meant she had power and did not need to show it.
Mu Chen gave a small nod. "Thank you, ma'am."
Luo Wei looked at his badge and then at him again. "You're here as guide support. Temporary transfer."
Temporary. The word sat in the air.
Mu Chen kept his expression steady. "Understood."
Luo Wei turned slightly so the room could hear. "Listen. This is Mu Chen. Guide. He will work with us until further notice."
A few people said quick greetings. Not warm, not cold. Just enough to be polite.
A man with sharp eyes leaned back in his chair. He looked Mu Chen up and down like he was checking new gear.
"Late awakening, right?" he said.
Mu Chen's smile did not change. "Yes."
Someone else gave a small laugh. "Late awakening and a C rating. They really ran out of people."
Mu Chen let that pass too. It was better if they thought he was weak. Better if they expected nothing.
Luo Wei's gaze cut across the room. The laughter stopped.
"We don't waste time," Luo Wei said. "We have a briefing in ten. Mu Chen, you will observe first. You will not link without permission."
"Yes, ma'am."
"Good."
Mu Chen moved to the locker with his name printed on it. The locker was empty except for a headset and a standard med kit. No personal items. No welcome note. This was not a place that welcomed people.
He placed his duffel on the floor, then opened it and took out the few things he was allowed to keep. A toothbrush. A small towel. Socks. A plain notebook with no marks.
Nothing that told a story.
He felt eyes on him again. Not just normal eyes.
Sentinel eyes.
They did not look like anything special. But Mu Chen could feel the way their senses reached. Like invisible hands testing the air around him.
He kept himself quiet.
A guide could make a room softer without touching it. A high-level guide could do it by accident. Mu Chen did not let that happen. He held his power inside, tight and still, like a lake with ice on top.
The door to the room opened again.
The sound was not loud. But the room reacted.
Shoulders straightened.
Voices lowered.
Someone shifted their feet without meaning to.
Mu Chen turned his head.
A man walked in.
He was tall and strong, built like he belonged in combat and knew it. His uniform looked worn in the right places. His hair was slightly damp at the temples, like he had rinsed off and came straight here.
His face was calm.
Not gentle calm.
Controlled calm.
Mu Chen felt it right away. The air around the man was sharp, like metal left out in winter. Not because he wanted it that way, but because his senses were always too open.
This was Ye Fan.
Mu Chen did not need anyone to tell him. The name had weight. It lived in the small changes in the room.
Luo Wei looked at him. "You're late."
Ye Fan's eyes stayed flat. "Training ran long."
A few people looked away like they had seen this before.
Ye Fan's gaze swept the room. It moved fast and clean, like a scan.
Then it stopped on Mu Chen.
Mu Chen's smile stayed in place, polite and small. He did not look down. He did not challenge. He just held still.
Ye Fan did not blink.
For a second, Mu Chen wondered if Ye Fan could hear his heartbeat.
He controlled his breathing anyway.
Luo Wei spoke again. "Major Ye Fan. This is Lieutenant Mu Chen. New guide."
Ye Fan's eyes moved to Mu Chen's badge, then back to his face.
"C rating?" Ye Fan asked.
Mu Chen nodded. "Yes."
"Late awakening?"
"Yes."
Ye Fan's jaw tightened slightly, like he did not like either answer.
Mu Chen stayed calm. "I'll follow orders."
Ye Fan stared at him a moment longer.
Then he looked away, like he had decided Mu Chen was not worth his time.
But Mu Chen did not feel safe.
Not with that kind of sentinel.
Sentinels were built for danger. They could smell lies. Not always with words. With instinct. With senses that did not need proof.
Ye Fan walked to his locker and started checking gear. His movements were clean and exact.
Mu Chen watched him in the corner of his eye, careful not to stare.
A man stepped closer to Mu Chen and spoke quietly, like he did not want Ye Fan to hear.
"I'm Zhou Xiao," he said. "Don't take it personal. Ye Fan hates surprises."
Mu Chen nodded. "Understood."
Zhou Xiao's gaze flicked to Mu Chen's hands. "You're really C?"
Mu Chen gave a small laugh, like the question was silly. "Yes."
Zhou Xiao did not look convinced. But he also did not push.
Across the room, another person walked past carrying a tablet. Lin Lan. Slim, focused, quick eyes. Lin Lan glanced at Mu Chen once, then looked away, like saving the data for later.
Mu Chen knew that look.
Not trust. Not hate.
Interest.
Luo Wei clapped her hands once. Not loud, but it cut through the room.
"Briefing," she said.
Everyone moved toward the table.
Mu Chen took a place at the edge again. That was his role for now. Quiet. Observing. Useful only when told.
The screen lit up with a map and a few red marks.
Luo Wei spoke in a clear, even voice. "We have a signal loss in the old warehouse area. Drone feed went black. Thermal picked up movement. No civilian clearance."
Zhou Xiao leaned forward. "Anomaly?"
"Likely," Luo Wei said. "We go in, confirm, clean, and return."
The room got quieter.
Mu Chen watched the faces. Even trained people changed when they heard that word. Anomaly. It meant unknown rules. It meant fear you could not shoot.
Ye Fan stood with his arms crossed. He looked bored. But Mu Chen could feel the tightness under that bored look. Like a wire pulled too hard.
Mu Chen's instincts rose.
He could smooth it.
He could calm Ye Fan without anyone noticing. Just a soft push on the edge of his senses, just enough to lower the pressure.
Mu Chen did nothing.
Not yet.
Luo Wei tapped the screen. "Ye Fan, you're lead. Zhou Xiao, Lin Lan, with him. Support in the rear. Mu Chen, you observe. You do not link without permission."
Ye Fan's eyes slid to Mu Chen again.
"Observe," Ye Fan repeated, like the word tasted wrong.
Mu Chen met his gaze this time. Calm. Mild. Easy.
"Yes," Mu Chen said. "Observe."
Ye Fan's eyes narrowed slightly. It was small, but Mu Chen saw it.
Like Ye Fan was trying to decide what kind of guide Mu Chen was.
Mu Chen stayed quiet.
The briefing ended quickly. Luo Wei gave short orders. The team began to move.
People checked weapons, packed gear, tested comms. The base felt like a machine starting up. Smooth, practiced, cold.
Mu Chen clipped on his headset and tested the mic.
A small beep answered him.
He could feel the base watching him. Cameras in corners. Sensors in the ceiling. Systems that tracked heat and movement and maybe more.
The institute was not in the room, but its shadow was.
As Mu Chen stepped away from the table, Ye Fan passed close behind him.
Too close.
Mu Chen's skin prickled. Not fear. Awareness.
Ye Fan stopped.
Mu Chen stopped too.
Ye Fan's voice was low. "Stay out of my head."
Mu Chen turned his head slightly, slow and calm. "I wasn't in it."
Ye Fan stared at him.
Mu Chen did not move.
Behind Ye Fan's eyes, there was something restless. Something tired. Like Ye Fan lived one second away from a storm, every hour of every day.
Most guides would feel pity.
Mu Chen felt danger.
Ye Fan leaned in just a little, just enough that Mu Chen could feel the heat of him. "If you try anything," Ye Fan said, "I'll know."
Mu Chen's smile returned, polite and small. "Yes, Major."
Ye Fan's eyes sharpened at the word Major, like he liked being reminded of distance.
Then Ye Fan walked away.
Mu Chen let himself breathe again, slow and quiet.
He placed a hand on his own wrist for one second, like checking a pulse.
Control, he told himself.
Be small. Be normal. Be C.
Because if anyone here learned what he really was, they would not let him stay a person.
They would turn him into a resource.
Mu Chen looked at the door that led to the hallway, to the elevators, to the mission.
He followed the team.
His steps were steady.
His face was calm.
And inside, under all that calm, his power stayed silent and deep, like an ocean that had learned how to pretend it was only a cup of water.
