Chapter 4: The Rat Run

The Rat Run was not a tunnel. It was a rumor made of stone, a web of abandoned workings that predated the Azure Sky Sect's claim on the mountain. Slaves had chipped at these passages for generations, following thin veins of low-grade spirit stone until the veins ran out or the roof fell in. Most of the Run was dead ends and collapse. A man who entered without a guide would wander until his lamp burned dry and then sit in the dark until the mountain swallowed him.

Lin Cang had a guide.

The jade slip burned against his chest, not with heat but with direction. The flame inside leaned toward certain passages and recoiled from others, pulling him through gaps too narrow for an overseer's shoulders, around falls that had buried other runners, down slopes where the air tasted of cold surface wind rather than stagnant stone. He followed it without question. The Codex wanted him alive. Whatever hunger lived in the stone had plans for him that did not end in a collapsed tunnel.

Sometimes the flame's guidance made no sense to his eyes. It pulled him toward a crawlspace that looked too tight, only to widen into a clear gallery beyond. It recoiled from a passage that seemed safe, and moments later he heard the distant rumble of a fresh fall somewhere in that direction. The Codex could sense the mountain's moods in ways his flesh could not.

He did not trust it. But he used it. That was the closest thing to faith the mine had left him.

Xiao Rou weighed nothing in his arms. That frightened him more than the dark. A living person should have more resistance, more warmth, more will to keep breathing. She had folded into him like a bird with broken wings, her face pressed against his collarbone, her breath faint and uneven against his neck.

The poison was still inside her. He could feel it through their tentative contact, a black knot in her channels that the small flame had licked at but could not consume. Every few minutes a shiver ran through her that was not from the cold. Her fingers, where they gripped his robe, trembled with the effort of holding on.

"Stay awake," he said.

"I am trying."

"Try harder."

She made a sound that might have been a laugh. "You are not gentle."

"Gentle is for people who have time."

The passage widened into a low gallery where old timbers sagged overhead like the ribs of a dying animal. Skeletons in rotted slave clothes lay curled against the walls, their fingers still reaching toward freedom. He did not intend to join them. Each skeleton was a lesson in what happened to slaves who lagged, trusted the wrong path, or ran out of strength before they ran out of mountain.

Lin Cang counted seven bodies in the gallery. Three adults, one adolescent, two too small to guess, and one alone in a corner with a cracked skull and a stone in its hand. The last one had chosen to end the climb rather than continue it. He could not judge. He might have made the same choice once, before the jade slip found him.

"Who are they?" Xiao Rou whispered.

"People who ran out of time." He did not slow. "Do not pity them. Pity weakens your legs."

"I am not pitying. I am recognizing." She coughed again, softer this time. "That one in the corner. I think I understand him."

"Do not understand him too well." Lin Cang shifted her weight. "Understanding leads to sympathy. Sympathy leads to sitting down. Sitting down leads to becoming a skeleton."

"You are very practical about death."

"I have had practice."

Xiao Rou coughed, a wet, ugly sound. Blood flecked his shoulder.

"Put me down," she whispered.

"No."

"You will die carrying me."

"Then I will die." He adjusted his grip and kept walking. "The Azure Sky Sect already wants me dead. I might as well die for something useful."

"I am not useful. I am dying."

"Not yet."

The flame in the jade slip stirred and reached toward Xiao Rou, hungry and patient, tasting the poison in her channels the way a wolf tasted wounded prey. It wanted her. Not her death, the flame did not feed on corpses. It wanted her surrender. Her choice. The moment she looked at him and believed he was the only wall between her and the dark.

Lin Cang understood the shape of it now. The Codex did not simply take. It bargained. A'Ling had given willingness and received a spirit stone and a little warmth. Xiao Rou would have to give more. She would have to give her survival into his hands.

The thought should have disgusted him. Two years ago, it would have. But the mine had burned away the luxury of disgust. The strong took. The weak were taken from. He had stopped being weak the moment he pulled the jade slip from the corpse's chest.

"Do you want to live?" he asked.

Xiao Rou was silent for a dozen steps. "Everyone wants to live."

"No. Some people stop wanting it. The mine does that." He ducked under a fallen beam, careful not to jar her. "You have not stopped yet. I can feel it. But you are close."

"What do you want me to say?"

"The truth."

"I am afraid." Her voice was smaller than the darkness. "I am afraid of dying. I am afraid of living. I am afraid that if I choose you, I will only be choosing a different kind of slave."

"You will be," he said. "But I will be your slave too. The bond works both ways. If you die, I lose what you give me. If I abandon you, the flame punishes me. We will be chained to each other, Xiao Rou. The only question is whether the chain is heavy enough to pull us both out of this hole."

She was quiet again. The tunnel narrowed until he had to turn sideways, Xiao Rou pressed against his chest, her breath shallow and fast against his neck. Behind them, somewhere in the maze, voices echoed. Not close, but coming. The overseers had found Thick Neck's body, or Black Scar's, or both. The hunt had begun.

"They will kill you for helping me escape," she said.

"They will try."

"Why take the risk?"

"Because the flame wants you." He said it without shame. "And because the Azure Sky Sect wants us both dead. Enemies of my enemies are useful, even if they are dying."

"The flame wants me," she repeated. "Not you?"

"I want to live. The flame wants to grow. You are where those desires meet." He squeezed through a tighter gap, her body pressed against his, and emerged into a passage where the air moved slightly. "Do not mistake me for a hero, Xiao Rou. Heroes die with clean hands. My hands will be dirty for the rest of my life."

"Then why tell me the truth? A villain would lie to make me grateful."

"Because gratitude built on lies collapses." The jade slip pulsed warm, approving or mocking, he could not tell. "The bond needs your real need, not a performance. If you choose me, choose me knowing what I am."

"And what are you?"

"A man the mine made into a weapon. A weapon that has decided to point itself at the people who forged it." He looked down at her. "For now, that is enough."

"That is not a reason to carry me."

"No." He stopped in the narrow passage and looked down at her. In the dim glow of the jade slip, her face was ghost-pale, her eyes enormous. "The reason is simpler. You looked at me and did not look away. In the barracks, when I touched you, you did not beg me to stop. You let me in. That is more trust than anyone has given me in two years. I will not waste it."

Xiao Rou's eyes filled with tears. She did not have the strength to wipe them. "I do not know if I can trust you."

"Then pretend." He started walking again. "Pretend until it becomes true."

The passage opened into a wider chamber. In the center, a vertical shaft rose into darkness. A grey circle of dawn waited at the top, distant and bright. Water dripped down the walls, cold and steady, the sound of a mountain weeping.

Lin Cang lowered Xiao Rou onto a flat stone and allowed himself a dozen heartbeats to breathe. The chamber was an old winze, perhaps, a vertical connection between workings. Rusted chain hung from a rotted pulley overhead, the remains of a hoist that had not moved in decades. The walls were slick with moisture and the faint luminescence of mineral deposits.

Somewhere above, a bird called. The sound was so foreign, so free, that both of them looked up.

"That is the surface," Xiao Rou breathed.

"That is the surface." He crouched beside her. "And that is where liars and slavers and worse things wait. Do not think freedom begins there. It only begins if we are clever enough to stay alive."

She nodded, though her eyes stayed fixed on the grey circle.

Lin Cang set Xiao Rou down against the wall of the shaft. Her head lolled to one side. He took her face in both hands and forced her eyes to open. Her skin was cold and clammy under his fingers. The blue tint had returned to her lips, fainter than before but unmistakable. The climb, or the poison, or both, had pushed her to the edge.

"Listen to me," he said. "I am not a good man. I have killed two men tonight and I will kill more. I am not saving you because I am kind."

Her eyes focused on him, barely. Her lips moved, but no sound came out.

"I found an art in the mine. It can keep you alive, but it needs something from you. Not your body yet. Not unless you choose. It needs you to want to live. It needs me to be the reason." He pressed her palm against the jade slip. The flame leaped toward her touch like a dog recognizing its master. "If you give me that, I will climb out of here carrying you. If you do not, I leave you and climb alone. Choose now."

"And if I choose wrong?"

"There is no wrong choice. There is only alive or dead." He leaned closer, his shadow falling across her face. "I am not asking for love. I am not asking for forever. I am asking for the next handhold, the next breath, the next hour. Give me those, and I will give you back a life."

Her eyes searched his. Looking, perhaps, for the lie. Looking for mercy. Looking for a reason to believe that the world contained anything besides pain and the people who dealt it.

He did not soften his expression. He had no softness to offer. Only certainty.

He pressed her palm harder against the jade. The flame glowed between their skin, crimson and hungry.

"I am climbing that shaft," he said. "If you want to live, climb with me. If you cannot climb, let me carry you. Let me be the reason you do not close your eyes."

She did not respond. Her eyelids fluttered. Her breath hitched.

Then her fingers tightened around the jade slip. Not much. The pressure of a child gripping a rope.

It was enough.
