Chapter 46
Lin Meihua's breathing had gone shallow, and Shen Yuan's hands didn't tremble as he measured ingredients—the furnace doesn't lie, and it was telling him she had three hours left.
"Moonshade root first." Yun Feilong was already moving, his movements precise despite the barrier shuddering around them. "The purification component needs a foundation that won't react with the toxins already in her system."
Shen Yuan nodded, crushing the silvery root between his fingers. The powder fell into the Heaven-Devouring Furnace like snow. "Temperature needs to stay below four hundred degrees. Any higher and the purification properties burn off."
"Agreed." Yun Feilong added three drops of something amber from a jade vial. "Celestial honey to bind the components. The original formula called for spirit honey, but that won't be strong enough for what we're attempting."
They moved around each other like dancers who'd rehearsed for years. Shen Yuan reached for an ingredient the same moment Yun Feilong stepped aside to give him room. When Yun Feilong needed the flame adjusted, Shen Yuan's hand was already on the control array.
Lin Meihua coughed. Wet and rattling.
"Phoenix ash," Shen Yuan said. "We need something that resonates with her foundation. The toxins are wrapped around her core like—"
"Like parasitic vines." Yun Feilong was already pulling a small pouch from his robes. "I have some. Collected from the Vermillion Peaks three centuries ago." He paused. "I was saving it for something important."
"This qualifies."
The ash went into the furnace. The flames turned gold, then white, then a color that hurt to look at directly. Shen Yuan felt the heat on his face, but his hands stayed steady as he added the next component.
"The formula calls for dragon's blood here," Yun Feilong said, studying the scorched notes. "But we don't have any, and substitutes won't—"
"Use mine."
Yun Feilong looked up sharply. "Your blood isn't—"
"I was the Pill Emperor for eight hundred years." Shen Yuan pulled a small knife from his belt. "My blood remembers things this body doesn't." He cut his palm before Yun Feilong could argue. Three drops fell into the furnace, and the flames screamed.
The barrier collapsed entirely. Reformed. Collapsed again.
"They're breaking through," Lin Meihua whispered from where she lay against the wall. Black veins had spread to her forehead now, branching like lightning scars. "You should—" Cough. "Should run while you—"
"Shut up," Shen Yuan said without looking away from the furnace. "We're busy."
She laughed. It turned into another cough, but she was smiling when it ended.
"Essence of void lotus," Yun Feilong said. "To create space within her foundation for the toxins to be expelled. Without it, the purification will have nowhere to push the poison."
"Don't have any."
"I do." Yun Feilong produced a crystal vial containing something that looked like liquid starlight. "This is the last of it. There are no more void lotuses in the world—they went extinct during the Cataclysm Wars."
Shen Yuan took the vial carefully. "You're using a lot of irreplaceable ingredients for someone who wanted me dead two days ago."
"For the good of all cultivators," Yun Feilong said, but his voice was dry. Almost amused. "Isn't that what I always say?"
"You do say that a lot."
"It's even true sometimes."
The void lotus essence went into the furnace. The flames inverted, burning downward instead of up, and the temperature dropped so fast frost formed on the furnace's exterior.
"Now the binding agent," Shen Yuan said. "Something to hold all these contradictory elements together without letting them neutralize each other."
They both reached for the same ingredient at the same time. Their hands collided over a jar of crystallized time-essence.
"You were going to use this?" Yun Feilong asked.
"You were too?"
"It's the only thing that makes sense. Everything else would either be too weak or would react with the phoenix ash."
Shen Yuan opened the jar. The crystals inside pulsed with a rhythm like a heartbeat. "This is going to be expensive."
"She's worth it."
They added the time-essence together, each taking half. The furnace made a sound like a bell being struck, and the flames stabilized into a perfect sphere of white fire.
"How long?" Lin Meihua's voice was barely audible.
"Two hours of refinement," Yun Feilong said. "Maybe less if we push it."
"I don't have two hours."
Shen Yuan looked at her. The black veins had reached her eyes now, threading through the whites like cracks in porcelain. Her lips were blue. "Then we push it."
One hour later, Shen Yuan's hands were cramping and his vision was starting to blur from staring at the furnace's light. Yun Feilong looked worse—his face was gray, and he'd started coughing about twenty minutes ago.
"Almost there," Yun Feilong said. "The final binding is forming. Once it solidifies, we can begin the condensation phase."
"The condensation is going to be the hard part." Shen Yuan adjusted the flame temperature down by three degrees. "We need to compress all these elements into a single pill without losing any of the purification properties."
"I'm aware."
"Just making sure we're—"
"I've been refining pills since before your first life was born, Shen Yuan. I know how condensation works."
"You also thought adding mercury to foundation pills was a good idea."
Yun Feilong's teeth pressed together. "That was different."
"Was it?"
"Yes." Yun Feilong's voice went flat. "That was arrogance. This is desperation. There's a difference."
Lin Meihua made a sound that might have been a laugh or might have been choking. "You two are—" Cough. "Are really bad at working together, you know that?"
"We're doing fine," Shen Yuan said.
"You've insulted each other six times in the last hour."
"Only six?" Yun Feilong raised an eyebrow. "I thought it was more."
"I wasn't counting the subtle ones."
The furnace pulsed. The sphere of flame began to contract, compressing inward. Shen Yuan and Yun Feilong both moved at once, their hands flying over the control arrays, adjusting temperature and pressure in perfect synchronization.
"Now," Yun Feilong said.
"Now," Shen Yuan agreed.
They pushed their qi into the furnace together. The sphere compressed further, smaller and smaller, until it was the size of a fist, then an eye, then a pearl. The light was so bright it cast shadows through their hands.
"It's forming," Yun Feilong said. "The pill is—"
The light went out.
For a moment, there was only darkness and the sound of Lin Meihua's labored breathing. Then the furnace opened, and a single pill rolled out onto the workbench.
It was perfect. Flawless white surface with veins of gold running through it like rivers. It pulsed with a gentle warmth, and the air around it seemed cleaner somehow, as if the pill was purifying its surroundings just by existing.
Shen Yuan reached for it. His fingers were an inch away when Yun Feilong grabbed his wrist.
"Wait."
"What?"
"Look at it. Really look."
Shen Yuan looked. The pill was beautiful, perfect, exactly what they'd been trying to create. And in its center, barely visible, was a hollow space. A void where something should be.
"It's incomplete," Yun Feilong said quietly. "We created the structure, but it needs a catalyst. Something to activate the purification properties."
"What kind of catalyst?"
Yun Feilong was silent for a long moment. When he spoke, his voice was careful. Measured. "A piece of a cultivator's foundation. Willingly given. The pill will use it as fuel to purge the toxins from her system."
"How much of a foundation?"
"Enough to matter. Three levels, maybe four. The refiner would lose that cultivation permanently—it can't be recovered."
Shen Yuan stared at the pill. At Lin Meihua, whose breathing had gone so shallow he could barely see her chest moving. At Yun Feilong, who was watching him with an expression that might have been pity.
"The furnace doesn't lie," Shen Yuan said.
"No. It doesn't."
"And this is the only way?"
"Yes."
Shen Yuan picked up the pill. It was warm in his palm, pulsing like a second heartbeat. He walked over to where Lin Meihua lay and knelt beside her.
"Hey," he said softly. "I need you to stay awake for a few more minutes."
Her eyes opened. They were almost entirely black now, the veins having consumed most of the white. "Shen Yuan?"
"I'm here."
"I can't—" Cough. "Can't see very well."
"That's okay. You don't need to see for this." He held up the pill. "We finished it. The Flawless Foundation Pill. It's going to fix everything."
"Really?"
"Really."
She smiled. Blood on her teeth. "That's good. That's—" Her eyes closed. "That's really good."
Shen Yuan stood. Walked back to the furnace. Yun Feilong was still standing there, watching him.
"I'll do it," Shen Yuan said. "I'll provide the catalyst."
"You're already crippled. If you lose three more levels—"
"I'll be weaker than a mortal. I know." Shen Yuan placed the pill back on the workbench. "But I'm the one who got her into this. I'm the one who brought her to the Outer Pill Hall, who involved her in all of this. It should be me."
"That's not how—"
"It's how it works for me." Shen Yuan started pulling off his outer robe. "Tell me what I need to do."
Yun Feilong didn't move. He was staring at Shen Yuan with an odd expression, something between respect and sorrow. "You've changed," he said quietly. "The Pill Emperor would never have done this."
"The Pill Emperor is dead."
"Is he?"
Shen Yuan didn't answer. He placed his hands on the furnace, feeling the residual heat against his palms. "What do I need to do?" he repeated.
"Shen Yuan—"
"Tell me."
Yun Feilong opened his mouth. Closed it. Then he did something Shen Yuan had never seen him do before—he rolled up his sleeves.
Black veins covered his arms from wrist to elbow. They pulsed with a sickly light, and the skin around them was gray and dead-looking.
Shen Yuan stared. "What—"
"The poison I used to kill you," Yun Feilong said. His voice was steady, but his hands were shaking. "It was called Eternal Regret. Very poetic name for something that dissolves a person from the inside out. I coated Xiaoli's pill with it, knowing you'd refine it, knowing you'd absorb trace amounts through your skin during the process."
"I know what you did."
"Do you know what it cost me?" Yun Feilong's laugh was bitter. "I had to handle the poison to apply it. I took precautions, of course. Wore gloves, used tools, held my breath. But Eternal Regret is insidious—it finds a way in. Always."
The black veins pulsed. Shen Yuan could see them moving under Yun Feilong's skin, writhing like living things.
"I've been dying for three thousand years," Yun Feilong continued. "Slowly. So slowly that most days I can pretend it's not happening. I've used every alchemical technique I know to slow it down, to contain it, to keep it from reaching my core. But it's still there. Still eating me alive."
"Why are you telling me this?"
"Because I'm going to provide the catalyst." Yun Feilong's voice was firm. "Not you."
"You can't—"
"I can. I will." Yun Feilong looked at Lin Meihua, then back at Shen Yuan. "You asked me once why I did it. Why I killed you. I said it was for the good of all cultivators, and that was true. But it was also because I was jealous. Because you were everything I wanted to be and could never achieve."
"Yun Feilong—"
"I've spent three thousand years trying to fix what I broke. Trying to create pills that heal instead of harm. Trying to be worthy of the title Celestial Pill Master." He laughed again, and this time it sounded almost genuine. "But everything I make is tainted. Everything I touch turns to poison eventually. Just like me."
"That's not—"
"It is." Yun Feilong placed his hands on the furnace beside Shen Yuan's. "But this—this I can do right. I can give my cultivation to save her. I can use the poison that's been killing me as fuel for something good. For once in my miserable existence, I can create something that doesn't destroy."
Shen Yuan wanted to argue. Wanted to push Yun Feilong away and do it himself. But he looked at the black veins on Yun Feilong's arms, at the gray tinge to his skin, at the way his hands shook even as he held them steady.
"How long have you been in pain?" Shen Yuan asked quietly.
"Every day since I killed you."
"That's not what I meant."
"I know." Yun Feilong smiled. It was a sad smile, but genuine. "Let me do this, Shen Yuan. Let me do one thing right before I run out of time entirely."
The process took fifteen minutes. Yun Feilong sat cross-legged before the furnace, the Flawless Foundation Pill floating in the air between his hands. His qi flowed into it, visible as streams of silver light that pulsed and writhed as they were absorbed.
Shen Yuan watched as Yun Feilong's cultivation dropped. It was visible in the way his aura dimmed, in the way his breathing became more labored, in the way the air around him grew still and heavy.
"That's one level," Yun Feilong said. His voice was strained. "Two more to go."
"You don't have to—"
"Yes. I do."
More qi flowed into the pill. The hollow space in its center began to fill with light, golden and pure. The pill's surface started to glow, brighter and brighter, until it was almost painful to look at.
"Two levels," Yun Feilong gasped. "One more."
"That's enough," Shen Yuan said. "The pill is—"
"Not finished." Yun Feilong's face was gray now, sweat running down his temples. "It needs three. The formula requires three."
"Yun Feilong—"
"Shut up and let me concentrate."
The final level took the longest. Yun Feilong's hands were shaking so badly the pill almost fell twice. His breathing was ragged, and the black veins on his arms had spread to his neck, visible above his collar.
But he didn't stop. He poured the last of his third cultivation level into the pill, and when he was done, the hollow space was completely filled. The pill was perfect now, truly perfect, glowing with a light that seemed to come from somewhere beyond the physical world.
Yun Feilong caught the pill as it fell. He held it out to Shen Yuan with trembling hands. "Give it to her," he said. "Quickly. Before—" He coughed. "Before I pass out and drop it."
Shen Yuan took the pill. It was hot in his palm, almost burning, but the heat felt clean. Pure. He walked over to Lin Meihua and knelt beside her again.
"Meihua," he said. "I need you to swallow this."
Her eyes opened. Barely. "Is it done?"
"It's done."
"Did you—" Cough. "Did you sacrifice your—"
"No. Yun Feilong did."
Her something crossed her face slightly. "He—"
"Don't talk. Just swallow."
He placed the pill in her mouth. She swallowed with difficulty, her throat working. For a moment, nothing happened.
Then she screamed.
Her back arched off the ground, every muscle in her body going rigid. The black veins on her skin began to glow, pulsing with a sickly light. Her mouth opened wider, and black smoke poured out, thick and oily and wrong.
"Hold her down," Yun Feilong said. He was on his knees now, too weak to stand. "The pill is purging the toxins. If she thrashes too much, she could hurt herself."
Shen Yuan grabbed her shoulders, pinning her to the ground. She was burning hot, her skin almost too hot to touch. More black smoke poured from her mouth, her nose, even her eyes. It pooled on the ground around her, writhing like something alive.
"How long does this last?" Shen Yuan asked.
"I don't know. I've never seen a purification this aggressive."
Lin Meihua screamed again. The black veins on her skin began to recede, pulling back from her face, her neck, her arms. But as they retreated, they left behind raw, burned skin, as if they'd been seared away.
"It's working," Yun Feilong said. "The pill is—"
He stopped. His eyes went wide.
Lin Meihua's eyes had opened. They were glowing. Not with the black light of the toxins, but with pure phoenix fire, gold and red and white all at once. The flames didn't burn—they were cool, almost soothing, but they were unmistakably fire.
She sat up slowly. Shen Yuan released her shoulders, and she turned to look at him. Her eyes were still glowing, still burning with that impossible fire.
"I can see it now," she whispered. Her voice was different—layered, as if multiple people were speaking at once. "The poison in both of you. The same poison. Connected like roots."
"What are you—"
She reached out and touched Shen Yuan's hand. Then Yun Feilong's. Her fingers were warm, and where they touched, Shen Yuan felt something shift inside him. Something he hadn't known was there.
The black veins in all three of them began to burn.
