The day after the Seeker's attack, the sect smelled of dust and blood.
Cain sat on a bench outside the medical hall, his arm wrapped in bandages that did nothing to stop the dull, throbbing ache. The wound from Han Xian's dagger refused to close. Every few hours, a thin trickle of blood seeped through the cloth, and the edges of the cut remained raw and red.
*Designed to suppress regeneration. Yin Wuji's scar took years to fade.*
Su Yao emerged from the hall, her cracked ribs bound, her flute replaced with a spare. She moved carefully—still sore—but her eyes were clear.
"Your turn," she said. "The healers want to examine the wound again."
"They won't find anything new."
"They might. Yin Wuji arrived an hour ago. He's in the back with Elder Tao."
Cain stood and walked inside. The medical hall's back room was cluttered with jars, scrolls, and the particular smell of old blood and older remedies. Yin Wuji sat on a stool, drinking from his gourd, a jar of thick red paste on the table beside him.
"Seeker's blade," the old man said without preamble. "I know that wound. Sit."
Cain sat. Yin Wuji peeled back the bandage, examined the cut, and grunted.
"Still fresh. The dagger's residue is bonded to your blood origin. Normal healing won't touch it." He pushed the jar forward. "Bloodstone paste. Spread it on the wound twice a day. It'll hurt like hell, but it'll neutralize the residue in about a week."
"A week?"
"You're lucky it's not a month. The Seeker's blade is designed to keep blood cultivators bleeding until they die or cut off the limb." Yin Wuji took a long drink. "You're alive because Su Chen drove him off before he could deepen the cut."
Cain took the jar. "How do I kill him?"
"You don't. Not yet." Yin Wuji's voice was flat. "Han Xian is Core Formation. You're Blood Condensation—equivalent to Foundation peak, maybe early Core on a good day. He's faster, stronger, and his whole existence is built to counter people like you."
"Then what do I do?"
"You train. You prepare. And you don't fight him alone." Yin Wuji looked toward the door, where Su Yao was waiting. "That girl's wood qi is a problem for him. His dagger suppresses blood, not life energy. If you fight together—she heals, you attack—you might survive long enough for Su Chen to intervene again."
He paused, rubbing his chin. "One more thing. The Seeker's dagger needs blood to recharge. It drains itself with each use. If you can wound him—draw enough of his own blood—the blade will turn on him. It's a risk, but it's the only weakness I know."
*Survive. Not win. Survive. But now there's a chance.*
"I'll take it."

Cain spent the afternoon applying the bloodstone paste. The pain was immediate and absolute—like fire eating through his veins—but after an hour, the wound's edges finally began to dry. His regeneration wasn't working, but at least the bleeding had stopped.
Su Yao found him in his quarters as the sun began to set.
"There's something else," she said. "My maid. Xiao Lian. You remember I told you her cultivation was unstable?"
Cain nodded.
"It's worse now. The healers say her spiritual foundation is cracking. If nothing changes, she has weeks—maybe days." Su Yao's voice was steady, but her hands were clasped tight. "She asked to see you."
"Why me?"
"Because she knows what you are. And because—" Su Yao hesitated. "—because she heard about the Seeker. About how he hunts blood cultivators. She said… she said she'd rather be something useful than die as nothing."
*She wants me to turn her. A willing donor.*
"Take me to her."
---
Xiao Lian's room was in the servants' quarters—small, clean, a single spirit lamp casting pale light. The girl lay on a cot, her face pale, her breathing shallow. She couldn't have been more than eighteen.
When she saw Cain, she tried to sit up. Su Yao gently pressed her back down.
"You're the blood cultivator," Xiao Lian said. Her voice was weak but clear. "The one who killed the dragon."
"I'm the one who survived a dragon," Cain said. "That's different."
"Su Yao trusts you. That's enough for me." She met his eyes. "I'm dying. The healers can't stop it. But you can. Turn me into one of your… your progeny. Let me live. Let me help."
*A willing donor. The first one who isn't dying from violence.*
"It will change you," Cain said. "You'll crave blood. You'll be sensitive to sunlight. Your cultivation path will shift—you won't be able to follow orthodox techniques anymore."
"I can't follow them now. My foundation is already cracking." She smiled—a fragile, determined thing. "At least this way, I can still stand beside her."
She looked at Su Yao. Su Yao's eyes were wet.
*She's not asking for herself. She's asking for her friend.*
"Lie still," Cain said. "This will hurt."
---
The transformation took an hour.
Cain had never performed a progeny bond before. The dragon's memories gave him the theory—blood sharing, origin linking, the careful transfer of essence that tied a new vampire to their progenitor. But theory and practice were different.
He cut his palm. Xiao Lian cut hers. They pressed their wounds together.
Cain's blood nucleus pulsed. A thread of his essence flowed into Xiao Lian—not the crude feeding of combat, but a deliberate, careful transfer. He felt her spiritual foundation, cracked and crumbling, and he didn't repair it. He *replaced* it. His blood wove through her veins, creating new channels, new pathways, a new origin that wasn't qi but blood.
Her body arched. She gasped—not in pain, but in *recognition*, as if something long dormant had finally awakened. Her skin flushed, then paled. Her heartbeat stuttered, then found a new rhythm—slower, deeper, matched to Cain's own.
Then it was done.
Xiao Lian's eyes opened. They were different now—darker, deeper, with a faint red tint at the edges. Her breathing was steady. Her pulse was slow.
"I'm… hungry," she whispered.
Su Yao fetched a small cup of warm rabbit blood from the kitchen. Xiao Lian drank it in one gulp, grimaced, then licked her lips. "It's… not terrible."
"That's normal," Cain said. "Animal blood first. We'll find you spirit beast blood when you're stronger."
She sat up slowly, testing her limbs. Her fingers curled and uncurled. Her smile was wider now—genuine, almost giddy.
"I can feel everything. The bamboo outside. The disciples in the courtyard. Their heartbeats." She looked at Su Yao. "I can feel *you*."
Su Yao pulled her into a hug. "You idiot. You scared me."
"Sorry. Won't happen again." Xiao Lian's voice was light, but her eyes found Cain's over Su Yao's shoulder. "Thank you. I won't forget what you gave me."
*What I gave her. A second chance. And a leash.*
"You'll need to learn control," Cain said. "Your senses will be overwhelming at first. The hunger will be constant. But it fades."
"How do you know?"
"Because I've been doing this for three hundred years."
Xiao Lian's eyes widened. Then she laughed—a surprised, delighted sound. "Three hundred years. And you still look like that."
"Vanity is eternal."
Su Yao pulled back, wiping her eyes. "We need to tell my father."
"Tomorrow," Cain said. "Tonight, let her rest."
---
The next morning, Cain and Su Yao began their training.
The waterfall cave became their practice ground. Yin Wuji watched from his usual rock, offering commentary between drinks.
"Again," Cain said.
Su Yao raised her flute. A piercing note cut through the cave—not aimed at him, but at a practice target he'd set up across the pool. The target's spiritual formation flickered.
"Good. Now hold it."
She held the note. The formation flickered faster, then cracked.
"Your sound techniques destabilize spiritual structures," Cain said. "That's useful against the Seeker's dagger. If you can disrupt its resonance, it might lose its edge."
"That's a theory."
"It's a hypothesis. We'll test it when we're ready."
He dissolved into blood mist, flowed across the pool, and reformed behind her. She didn't flinch.
"Your mist form is faster," she said.
"Practice. I need to be able to use it in combat without thinking." He raised his hand. Three blood needles formed in the air, each aimed at a different target. "And I need to maintain these while moving."
He released the needles. Two hit their marks. The third went wide.
"Three is too many," he said. "I'll stick with two until my control improves."
They drilled the combination for an hour. Su Yao's flute destabilized a new target; Cain's blood needle struck the exposed core before the resonance faded. Yin Wuji grunted approval. "Better. Now do it faster."
By the third session, they'd found a rhythm. Su Yao didn't need to speak; Cain anticipated her notes. When she played low and long, he moved left. When she played high and short, he struck. It wasn't perfect—but it was progress.
"Progress, not perfection," Yin Wuji said. "You've got a week before the Seeker tries again. Maybe less. Use it well."
---
They trained until dusk. Cain's arm ached—the wound was healing, but slowly. Su Yao's ribs protested every time she took a deep breath. But they were getting better.
Xiao Lian joined them on the second day. Her new senses were raw, overwhelming—she flinched at every sound, every shift in spiritual pressure. But she was eager, and she learned fast.
"I can sense blood," she said, her eyes closed in concentration. "Not like you—not the details. But I can feel where it is. Living things. The deer in the forest. The disciples in the hall."
"That's your progenitor bond," Cain said. "Your senses will grow as mine do."
"Can I fight?"
"Not yet. But you can watch. You can learn. And when the time comes, you can warn us if someone approaches."
She nodded, determined. Then she tilted her head. "There's something strange. In the eastern storage sheds. One of the night guards—his heartbeat is wrong. Too slow. Like he's pretending to sleep."
Cain and Su Yao exchanged glances.
"We'll check it tomorrow," Su Yao said. "Good catch."
*She's already useful. More than I expected.*
---
On the third night, Cain sat alone in the cave, applying the bloodstone paste to his arm. The wound was finally closing—a thin line of pink scar tissue where the dagger had cut.
*Another week, and I'll be whole. Another week, and the Seeker will be back.*
He thought about Xiao Lian. Her willingness. Her trust. She had given herself to him not out of desperation, but out of loyalty to Su Yao. That was different from the dragon's sacrifice. Different from Mira's.
*This is what a progeny bond should be. Not a weapon. A connection.*
Su Yao found him as he was sealing the jar.
"You're brooding."
"I'm thinking."
"Same thing." She sat beside him, close enough that he could feel the warmth of her wood qi. "Xiao Lian is settling in. She ate her first spirit beast blood tonight—a rabbit. She said it tasted like copper and moonlight."
"That's surprisingly poetic."
"She's always been like that. Even before." Su Yao was quiet for a moment. "Thank you. For saving her."
"I didn't save her. I changed her. There's a difference."
"She wanted this. She chose it." Su Yao looked at him. "That's what matters."
Cain didn't answer. He watched the waterfall, listened to the roar, and thought about choices.
*I chose to stay. She chose to trust me. Xiao Lian chose to become my progeny.*
*Maybe that's what blood condensation meant. Not power. Connection.*
"We should rest," he said finally. "Tomorrow, we train again."
"Tomorrow," she agreed.
She didn't move. Neither did he.
They sat in the cave, shoulder to shoulder, and let the darkness settle around them.
