The corridor Helian Feng dragged Shen Lu into was narrower than the chamber behind them, the stone walls close enough that Shen Lu could feel cold seeping through his robe into his skin. The air here smelled sharper—metallic, ancient, and threaded with something faintly sweet that made Shen Lu's stomach roll.
Poison.
Not the kind that burned hot and obvious.
The kind that crept in quietly and then shut the body down like a door being barred from the inside.
Shen Lu's shoulder throbbed around the needle. The pain wasn't dramatic. It was dull, spreading, the way frost spread across a window pane. His fingers tingled, then began to lose sensation. His breath came shallow, each inhale scraping as if the air had turned too thick.
Helian Feng crouched in front of him, face tight with focus. Lightning flickered faintly along the edge of his sword sheath, not because he was striking, but because his spiritual root reacted to the pressure of danger like a living thing.
Shen Lu tried to speak and failed. His tongue felt heavy, as if the poison had reached his throat.
Helian Feng's gaze snapped to Shen Lu's face.
"Stay conscious," Helian Feng said, voice sharp.
Shen Lu's dry humor tried to surface and only managed to drip out, weak. "You're… very controlling…"
Helian Feng's eyes turned colder. "Save your breath."
He reached for the needle.
Shen Lu's instincts screamed. He grabbed Helian Feng's wrist with numb fingers. "Don't… touch… unless treatment."
Helian Feng stared at him.
For half a heartbeat, Shen Lu thought Helian Feng might actually laugh—not from amusement, but from disbelief that Shen Lu could still insist on boundaries while half-frozen.
Helian Feng didn't laugh.
"This is treatment," Helian Feng said flatly, and yanked his wrist free.
He gripped the needle's base with two fingers and pulled.
The needle slid out smoothly, almost too easily, like it had been designed to leave the body cleanly while the poison stayed behind.
A thin bead of dark blood rose from the puncture.
Helian Feng's jaw tightened. He pressed a cloth against the wound, then moved his fingers to Shen Lu's wrist again, checking pulse and qi flow with the cold efficiency of someone who didn't trust anyone else to assess danger.
Shen Lu's eyes fluttered. He fought to keep them open.
The corridor behind them shook faintly as something struck the sealed passage—rivals or the bone-guardian or both. The talisman seals the team had slapped onto the stone glowed pale gold, then dimmed, holding.
Helian Feng's voice snapped out, angled toward the shadowed doorway. "Report."
One talisman disciple appeared in the corridor entrance, breathing hard, face pale. "The chamber is lost. Rival groups are fighting over the shard. We sealed the passage but they're pressing. We can hold for a short time."
Helian Feng's gaze stayed on Shen Lu. "How many are we."
"Seven," the disciple said, voice tight.
Seven.
One missing.
Shen Lu's stomach turned again, cold and heavy.
Helian Feng's jaw clenched once. "The outer disciple?"
The talisman disciple hesitated. "Gone."
Helian Feng didn't react outwardly. But Shen Lu saw it in the smallest shift of his eyes, the minute tightening around his mouth. Not grief. Not softness. Something like a tally being carved deeper.
Helian Feng looked back at Shen Lu and spoke as if cutting a decision into stone.
"We move deeper," Helian Feng said.
The talisman disciple swallowed. "Senior Brother Helian, Shen Lu—"
Helian Feng's gaze turned icy. "He will walk."
Shen Lu wanted to laugh and couldn't. He wanted to say, I'm not walking, I'm being dragged. Instead, he focused on one thing: not blacking out.
Helian Feng stood and hauled Shen Lu upright with a grip at his forearm, hard enough to bruise. Shen Lu's legs almost buckled immediately. Numbness crawled up his calves like slow water.
Helian Feng didn't let him fall.
He held Shen Lu steady the way a person held a dangerous object steady: firm, controlled, unwilling to be cut.
"Can you circulate your qi," Helian Feng asked, voice low.
Shen Lu tried. He reached inward, searching for the flow that should have been there. He felt it stuttering, interrupted, as if the poison had placed ice blocks along the channels.
"Barely," Shen Lu rasped.
Helian Feng's eyes narrowed. "What poison is it."
Shen Lu's mind flickered through memory. In the book, it had been described as a meridian-freezing toxin, designed to disable cultivators by locking their qi pathways. The cure had been rare. The method to purge it had been worse.
Shen Lu's tongue stuck to the roof of his mouth.
Helian Feng's gaze sharpened. "Answer."
Shen Lu forced words out. "Freezing type. Locks meridians."
Helian Feng's eyes narrowed further, as if parsing how Shen Lu knew that with such certainty.
Shen Lu saw the suspicion forming again, that cold shape in Helian Feng's gaze. Helian Feng didn't accept convenient knowledge. Convenient knowledge was a lie in a righteous man's world.
Shen Lu's dry humor, faint but stubborn, surfaced. "I'm an alchemist. Poison tends to interest us."
Helian Feng's gaze didn't soften. "You're not that good."
The words hit like a slap, not because they were insulting but because they were too true. Shen Lu wasn't good. He had book knowledge. He had a body that remembered things. But right now, his cultivation was unstable, his technique unpracticed, his survival dependent on a man who wanted him dead.
Helian Feng turned to the talisman disciple. "Lead. Find a safe chamber."
The group moved.
They went deeper into the corridor maze, away from the altar chamber. The stone walls were carved with faded sword motifs. Sometimes faint lines on the floor glowed as Helian Feng's sword qi brushed them, responding to thunder-root resonance.
Shen Lu stumbled as he walked. Helian Feng kept a hand on his arm, controlling his pace. It felt humiliating. It also felt like the only reason Shen Lu remained upright.
Yuan's presence under Shen Lu's collar was restless. Shen Lu felt his hunger, his excitement, his desire to bite something. But Yuan stayed silent, perhaps sensing that speaking aloud now would expose him and create a new disaster.
They reached a narrow side chamber and sealed the entrance with talismans. The talisman disciples worked quickly, slapping paper charms and pressing qi into them until the doorframe glowed faintly. The beast tamer's fox-spirit crouched near the entrance, ears pinned, ready to warn.
Helian Feng shoved Shen Lu down against the stone wall.
Not gently. Not cruelly either. Just efficiently, the way you set a fragile object down before it shattered.
Shen Lu's shoulder hit stone. Pain flared, then dulled under ice.
Helian Feng crouched again, gaze locked on Shen Lu's face. "You pushed me."
Shen Lu blinked. "Yes."
Helian Feng's eyes narrowed. "Why."
Shen Lu's mouth went dry.
Because I knew it was coming, Shen Lu thought, panic rising. Because I saw the needle in the book. Because I remembered the scene.
He couldn't say any of it.
So Shen Lu chose the most believable answer.
"Because if you died," Shen Lu said hoarsely, "the team dies."
Helian Feng's gaze didn't move. "You think I can die from a needle."
Shen Lu's dry humor slipped out, weak. "Everyone can die from a needle. It's an efficient invention."
Helian Feng's jaw tightened.
He didn't look amused. He looked more suspicious.
"You knew where it would come from," Helian Feng said quietly.
Shen Lu froze.
Helian Feng continued, voice calm as a blade. "You moved before you saw it. Your body reacted like you expected it."
Shen Lu's heart hammered.
Words that shouldn't exist again. Not literal words this time, but knowledge. Reflex. Timing.
Helian Feng's gaze pinned him. "How."
Shen Lu forced himself to breathe, shallow and controlled.
He needed the lie now.
The lie that would cover everything else.
"Old records," Shen Lu said, voice rough. "I've read old realm records. They said rival cultivators use shadow needles here. It's a common assassination method."
Helian Feng's eyes narrowed. "Old records told you the needle would strike my back at that moment."
Shen Lu swallowed. "They… described the type of tactics rival sects use near relic altars. It was instinct."
Helian Feng stared at him for a long moment, eyes cold and unreadable.
Shen Lu felt sweat slick his spine despite the poison's cold.
Helian Feng finally spoke, and the words were quiet, measured, and terrifying.
"You lied before," Helian Feng said.
Shen Lu's throat tightened. "About what."
Helian Feng's gaze sharpened. "About the bone-guardian."
Shen Lu's stomach dropped.
Helian Feng continued, voice even. "You blurted out a warning. You claimed you read an old realm record. You knew the timing."
Shen Lu's pulse spiked.
Helian Feng's voice didn't rise. It didn't need to. "Now you claim old records again."
Shen Lu forced calm into his face. "Because it's true."
Helian Feng's eyes narrowed. "Then tell me where you read them."
Shen Lu's mind raced.
He could not say, In the book. He needed a real location. A believable source. Something that fit alchemy hall access and sect bureaucracy.
"The alchemy hall archive," Shen Lu said quickly. "A compilation of realm notes. Elders collect them from survivors. I read it when I was assigned to ingredient mapping."
Helian Feng's gaze held him, cold and sharp. "Who assigned you."
Shen Lu's stomach turned.
If he named Elder Liu, he would implicate him. Elder Liu might retaliate. But if he didn't name anyone, Helian Feng would see it as another evasion.
Shen Lu's dry humor rose faintly, then died. This wasn't a moment for jokes. This was a moment for survival.
"Elder Liu," Shen Lu said.
Helian Feng's eyes flickered. The smallest movement. Recognition.
Helian Feng's voice turned colder. "Of course."
Shen Lu's throat tightened. "What does that mean."
Helian Feng stared at him as if deciding whether to speak. Then he said, quietly, "It means your leash is tighter than I thought."
Shen Lu's chest clenched. He wanted to deny it, but he couldn't. The jade vial with the tracking mark. The way Elder Liu had spoken about usefulness. The way Shen Lu had been sent on this mission like disposable labor.
Helian Feng looked away for half a heartbeat, as if refusing to let something in. Then he looked back.
"Listen," Helian Feng said, voice low. "I don't care what games Elder Liu plays with you. I don't care if you want to reform. I don't care if you want to beg."
Shen Lu's fingers curled. "I'm not begging."
Helian Feng's gaze cut him. "Good. Begging disgusts me."
Shen Lu almost laughed despite himself. "We finally agree on something."
Helian Feng ignored it. His voice remained flat and cold. "I care about one thing. You will not become a weapon pointed at my team."
Shen Lu swallowed. "Then don't point me."
Helian Feng's eyes narrowed. "You think you're clever."
Shen Lu's mouth twitched, dry humor bleeding through pain. "No. I think I'm freezing."
Helian Feng's gaze snapped to Shen Lu's shoulder again, assessing. He pressed two fingers to Shen Lu's wrist, checking qi flow.
Shen Lu flinched. "Treatment only," he rasped.
Helian Feng's voice was ice. "This is treatment."
Shen Lu shut his mouth, teeth clenched.
Helian Feng's expression tightened as he felt the stuttering qi. "The poison is still spreading."
Shen Lu swallowed. "Then let me refine something."
Helian Feng's gaze sharpened. "With what furnace."
Shen Lu's mind flashed to the portable cauldron in Helian Feng's storage ring. In the book, that cauldron had been used in desperation. Here, desperation was already chewing on them.
Helian Feng saw the direction of Shen Lu's thought and his jaw tightened.
"You're going to tell me you can refine a cure in this condition," Helian Feng said.
Shen Lu's eyes narrowed. "I can try."
Helian Feng's voice lowered, cold and dangerous. "If you fail, you die. If you succeed, you will owe me more than you can pay."
Shen Lu's dry humor surfaced, thin and bitter. "I'm already bankrupt."
Helian Feng's gaze held him for a long moment.
Then, with controlled brutality, Helian Feng made the decision the way he made every decision.
He reached into his storage ring.
And pulled out a small portable cauldron.
