The library was supposed to be empty at midnight.
That was what Cai Ling had said, anyway. But as Shen Yuan crept through the darkened corridors with Lian Jie at his back and Wei Cheng bringing up the rear, he found himself wondering how much of what she said could be trusted. The jade token felt heavier in his sleeve than it should have, dragging at his arm like an anchor.
The eastern section of the fortress was different from the rest. Quieter. The green torches here burned lower, spaced further apart, leaving long stretches of darkness between pools of sick light. The walls were lined with doors that led to rooms Shen Yuan couldn't guess at—archives, maybe, or storage, or cells for prisoners no one wanted to admit existed.
"The library is at the end of this corridor," Lian Jie whispered. "Third floor. There's only one staircase. If someone wants to trap us, this is where they'd do it."
"Then we don't take the staircase."
"There's no other way up."
Shen Yuan stopped. He turned to look at her, her face half-illuminated by the nearest torch. "You said there were escape routes. Contingency plans."
"I said we needed them. I didn't say I'd found any."
Wei Cheng spoke from behind them, his voice barely audible. "There's a maintenance shaft on the west side of the building. It's meant for cleaning the ventilation channels, but a person could fit. Barely."
Lian Jie stared at him. "How do you know that?"
"I spent three months being nothing. Nobodies learn things. It's all we have."
Shen Yuan filed that away—another piece of evidence that Wei Cheng was more than he appeared, or perhaps exactly what he appeared, which in this place was valuable enough. A nobody who paid attention was still someone who paid attention.
"Show us," he said.
Wei Cheng led them past the library's main entrance—a pair of wooden doors that looked like they hadn't been opened in years—and around the side of the building, through a narrow gap between the stone wall and the mountain itself. The maintenance shaft was exactly where he said it would be: a square opening in the rock, just large enough for a slim person to crawl through, covered by a grate that swung open on unoiled hinges.
"The third floor opens up about twenty feet in," Wei Cheng said. "There's a junction where four shafts meet. From there, you can see most of the main room."
"You've been inside?"
"I've been everywhere. No one cares where a nobody goes."
Shen Yuan looked at the shaft. Dark. Tight. The kind of space that made his chest feel tight just looking at it.
"I'll go first," Lian Jie said. "If there's trouble, I'm the best fighter."
"You're also the largest," Wei Cheng said. "No offense. But if you get stuck, you block the whole shaft. I should go first. I'm smallest."
Lian Jie's jaw tightened, but she didn't argue. Wei Cheng slipped through the opening with the ease of someone who had done this many times before, his body folding into the darkness like water finding its level.
Shen Yuan went next.
The shaft was worse than he had imagined. The stone pressed against his shoulders, his hips, the top of his head. He had to turn his face to the side to breathe, and even then, the air was thick with dust and the smell of old metal. His hands found purchase on the rough rock, pulling him forward inch by inch. The cleaver at his belt scraped against the shaft wall, sending small showers of grit down onto his legs.
Twenty feet. Wei Cheng had said twenty feet. It felt like two hundred.
Then the shaft opened up.
He crawled out into a junction—four passages meeting in a small chamber no larger than a closet. Wei Cheng was already there, crouched against the wall, his narrow knife in his hand. He pointed upward.
Shen Yuan looked.
Above them, the third floor of the eastern library spread out like a cavern of paper and dust. Shelves rose from floor to ceiling, packed with scrolls and books and bound manuscripts in languages he didn't recognize. The green torches here were different—older, maybe, or enchanted differently—casting a light that was almost yellow, almost warm.
And in the center of the room, standing beside a reading table, was Cai Ling.
She was alone.
Shen Yuan had expected guards. Ambushers. At least one person hiding in the shadows with a knife. But the library was empty except for the woman with the silver pin in her hair, who looked up as he dropped down from the maintenance shaft and smiled.
"You came," she said.
"You said you had answers."
"I do." She gestured to the table, where a stack of documents lay spread across the surface. "But first, I need you to understand something. What I'm about to show you—if anyone finds out I showed you—I'm dead. Not punished. Not exiled. Dead. My brother is already gone. The rest of my family lives outside the fortress. They would be dead too."
Lian Jie dropped down from the shaft, landing silently beside Shen Yuan. Her sword was out. Her eyes never left Cai Ling's face.
"Then why are you doing this?" Lian Jie asked.
Cai Ling's smile faded. "Because my brother didn't deserve to die. And the person who killed him is still walking these halls. Still giving orders. Still pretending to be loyal to the sect while using it for his own purposes."
She picked up the top document from the stack—a sheet of parchment covered in dense handwriting, stamped with a seal Shen Yuan didn't recognize.
"Three months before the incident, someone began purchasing demon-summoning components on the black market. Blood crystals. Abyssal ink. A binding circle drawn in the hide of a stillborn child. These things are not easy to find, and they are not cheap. Whoever bought them had resources. Connections. Power."
She handed the document to Shen Yuan.
"I traced the purchases. It took me two months, and I almost died three times, but I traced them. They all lead back to the same source."
Shen Yuan looked at the parchment. The handwriting was cramped, difficult to read, but one name stood out at the bottom of the page.
Elder Xu.
"The same Elder Xu who controls resources," Shen Yuan said slowly. "The same Elder Xu who wants me dead."
"The same Elder Xu who reassigned your servants and stripped you of your protection," Cai Ling confirmed. "The same Elder Xu who has been building a power base for twenty years, waiting for the Heavenly Demon to show weakness. And the Heavenly Demon's only weakness—" She pointed at Shen Yuan. "Is you."
The room was very quiet.
Wei Cheng had not moved from his position near the maintenance shaft. His knife was still in his hand, but his eyes had gone wide, fixed on the document in Shen Yuan's hands.
"Why would Elder Xu want me to summon a demon?" Shen Yuan asked. "What does he gain?"
"Chaos. Fear. An excuse to move against your father." Cai Ling spread her hands. "The seventeen disciples who died—they weren't random. They were all loyal to the Heavenly Demon. Personal guards, trusted messengers, the children of old allies. With them gone, Elder Xu's people have been able to slip into positions of power. Every day, he gets stronger. Every day, your father gets weaker."
"And the demon? The possession?"
"Meant to kill you. But the demon was stronger than Elder Xu anticipated. Instead of just killing you and burning out, it rampaged. Killed more people than intended. Drew more attention." Cai Ling's voice hardened. "Elder Xu has been scrambling to cover his tracks ever since. That's why he wants you dead so badly. As long as you're alive, there's a chance you'll remember something. A chance you'll expose him."
Shen Yuan set the document down on the table. His hands were steady now. The shaking had stopped.
"How do I prove this?"
"You don't. Not yet. Elder Xu has been covering his tracks for twenty years. He's good at it. If you go to your father with this now, Elder Xu will deny everything, produce alibis, and have you executed for slandering a member of the elders' council." Cai Ling pulled another document from the stack. "But there's a record. A complete accounting of every transaction, every shipment, every person involved. It's kept in Elder Xu's personal vault, in his compound on the northern peaks."
"Let me guess," Lian Jie said dryly. "You know how to get in."
"I know someone who knows. A woman who works in Elder Xu's kitchens. She's been there for ten years. She's seen things. Heard things. And she's willing to talk—for a price."
"What price?"
"Protection. When this comes out, when Elder Xu falls, she wants to be somewhere else. Somewhere safe. She wants your word that you'll make that happen."
Shen Yuan looked at Lian Jie. Looked at Wei Cheng. Looked back at Cai Ling.
"You're asking me to break into an elder's compound, steal evidence, and smuggle out a witness. With no cultivation, no army, and no guarantee that any of this is real."
"Yes."
"That's insane."
"Probably." Cai Ling's eyes didn't waver. "But it's the only chance you have. If you wait, if you try to rebuild your cultivation first, if you try to do this the safe way—Elder Xu will kill you. Maybe not tomorrow. Maybe not next week. But soon. And when he does, no one will even remember your name."
Shen Yuan thought about the stone slab. The cold. The green flames. The father who had looked at him with eyes that matched his own and said don't make me regret this.
"Where does the kitchen woman live?"
Cai Ling smiled. It was not a happy smile.
"The lower markets. The same cavern where you bought your knives. There's a stall that sells nothing but turnips, run by a man with no teeth. Tell him you're looking for pickled radishes. He'll take you to her."
"And when I find her?"
"She'll tell you how to get into the vault. After that, it's up to you."
Shen Yuan gathered the documents—all of them, not just the one with Elder Xu's name—and tucked them into his robe. The paper felt strange against his chest, thin and fragile and more dangerous than any weapon.
"One more thing," Cai Ling said as he turned to leave. "Your cousin. Shen Wei. He's working with Elder Xu."
Shen Yuan stopped.
"He doesn't know it," Cai Ling continued. "Or maybe he does. I haven't been able to determine that yet. But Elder Xu has been feeding him information, giving him resources, helping him build his power base. In exchange, Shen Wei has been undermining you. Making you look reckless. Unstable. Dangerous."
"That doesn't require much help from Elder Xu," Lian Jie muttered.
"No. But it explains why Shen Wei has been so successful lately. Why he's been given command of the Crimson Blades. Why your father trusts him more than he trusts you." Cai Ling's voice dropped. "Shen Wei is Elder Xu's backup plan. If the demon didn't kill you, Shen Wei would. And when you were dead, Shen Wei would take your place as the Heavenly Demon's heir—and Elder Xu would control him."
Shen Yuan felt something cold settle into his bones. Not fear. Something else. Something harder.
"Thank you," he said to Cai Ling. "For the information. For the risk."
"Don't thank me. Find out who killed my brother. That's all I want."
She turned and walked toward the library's main doors, her footsteps echoing in the silence. The green torches flickered as she passed, and then she was gone, swallowed by the darkness of the corridor beyond.
Lian Jie exhaled slowly. "Well. That was more than I expected."
"We need to move," Wei Cheng said. "If Cai Ling is working for Elder Xu—if this is all a trap—then every minute we stay here is a minute we could be walking into an ambush."
"She's not working for him," Shen Yuan said.
"You don't know that."
"No. But I know what she looked like when she talked about her brother. That wasn't acting." He turned toward the maintenance shaft. "We go to the lower markets tomorrow. We find the kitchen woman. We get into the vault."
"And if it's a trap?"
Shen Yuan put his hand on the cleaver at his belt.
"Then we fight."
---
They made it back to his room without incident.
Lian Jie barred the door from the inside—a heavy wooden beam that she had installed sometime in the past three days without telling him. Wei Cheng took up a position by the window, his narrow knife in his hand, his eyes on the corridor below.
Shen Yuan sat on his stone slab and spread the documents across his blanket.
Elder Xu. Shen Wei. A conspiracy that went back months, maybe years. Seventeen dead disciples, including Cai Ling's brother. A demon summoned to kill him that had killed so many others instead.
And at the center of it all, a question that gnawed at him like a rat at bone.
Why?
Not why Elder Xu wanted him dead. That was obvious enough—power, influence, control over the Heavenly Demon. But why him specifically? Why was he the key? He was just the son of the Heavenly Demon, a reckless fool who had done nothing but cause trouble his whole life. There were easier ways to destabilize the sect. Easier targets.
Unless there was something he didn't know. Something about himself. Something about his birth, his mother, the reason he had appeared at the fortress gates as a baby wrapped in black silk.
The notebook Lian Jie had given him—he hadn't finished reading it. Hadn't even gotten halfway. But he remembered the letter he had found buried in its pages, the one his past self had written to his father and never sent.
Why was I left at the gates? Why did you claim me? Did anyone ever want me?
Maybe those weren't just the questions of a troubled boy. Maybe they were the questions of someone who had begun to suspect the truth.
Shen Yuan folded the documents and tucked them back into his robe. Then he lay down on the stone slab, closed his eyes, and waited for morning.
Tomorrow, he would go to the lower markets.
Tomorrow, he would find the kitchen woman.
Tomorrow, he would take the first real step toward the truth.
But tonight, he would rest.
Because something told him that after tomorrow, rest would be hard to find.
