Chapter 4: The Poison in the Blood

Liang Yue stared at the liver cross-section, her medical training overriding her grief. The stained tissue showed something wrong—cells that shouldn't be there, structures that defied normal pathology.

"What am I looking at?"

Professor Li pointed to a cluster of dark spots. "Heavy metal deposits. Concentrated in the hepatic tissue, but also present in the kidneys, the lungs, the brain. This isn't environmental exposure. The distribution pattern is too precise."

"She was poisoned over time."

"Months. Maybe a year." He pulled out another photo—Grandma's right hand, nails slightly discolored. "The toxin leaves traces in keratin. But it's undetectable in standard toxicology screens. It mimics the body's own breakdown products."

Liang Yue's fingers traced the image. "What is it?"

"We don't have a name for it. But I've identified seven of its component compounds." He handed her a chemical analysis sheet. "Three are plant-based alkaloids. Two are synthetic. And two—" He paused. "Two come from human tissue."

"Human tissue? Like—"

"Bone marrow. Specifically, from cultivators who reached the Qi Condensation stage."

The furnace pulsed. Liang Yue felt heat crawl up her spine, a warning she didn't understand.

"You're saying they killed cultivators to make poison?"

"I'm saying they killed at least three cultivators to make *this* poison. The alkaloid compounds match samples from monks who died in Sichaun province over the past five years. Officially, natural causes. Unofficially—" He shrugged. "Disappearances that were never investigated."

"Because the Zhang family owns the police."

"Among other things."

Liang Yue closed the folder. Her hands had stopped shaking. Something cold and precise had settled in her chest, replacing the grief with a clarity she hadn't felt since Grandma's funeral.

"You said you have her body."

"In the morgue. Preserved."

"I need to see it."

"Are you sure? It's been three weeks—"

"I'm sure."

The morgue was in the basement of the medical school. Professor Li led her through corridors that smelled of formaldehyde and bleach, past janitors who didn't look up and security cameras that blinked red. He had a keycard that opened doors marked AUTHORIZED PERSONNEL ONLY.

They stopped at a door with a keypad. He typed a code—Grandma's birthday, Liang Yue noticed—and the lock clicked open.

The room was cold and white. Three steel tables stood in a row, two empty. On the third, a sheet-covered form.

Liang Yue approached slowly. The furnace in her dantian was burning now, not hot but *aware*, like a living thing waking from sleep.

She pulled back the sheet.

Grandma's face was peaceful. Too peaceful. The mortician had done good work, but Liang Yue saw what the photos had shown—the slight discoloration around the lips, the bruise-like shadows under the skin that makeup couldn't hide.

"Grandma," she whispered.

The furnace pulsed. Once. Twice.

And then Liang Yue *saw*.

It wasn't sight, not really. It was something else—a vision that bloomed behind her eyes like ink in water. She saw Grandma's last days. The tea that tasted bitter. The headaches that wouldn't stop. The woman who came to visit, young and beautiful, with eyes that held no warmth.

*Don't trust the Zhang family,* Grandma had said, but Liang Yue had thought she meant their business practices, their shady deals. Not *this*.

The vision shifted. A lab, modern and sterile. Tubes and vials and machines that hummed with power. A man in a white coat, his face familiar from the news—Zhang Ming, the eldest son of the Zhang family, smiling as he held up a syringe filled with golden liquid.

*The next generation of enhancement,* he said. *No more cultivation. No more alchemy. Just pure, efficient power.*

The syringe plunged into someone's arm. A young man, barely twenty, his face contorted in agony as golden veins spread across his skin.

*Side effects,* Zhang Ming said calmly. *We'll refine the formula.*

The vision shattered.

Liang Yue gasped, stumbling back. Professor Li caught her arm.

"What happened? Your eyes—they were glowing—"

"The furnace showed me," she breathed. "Grandma's memories. The Zhang family's lab. They're making the poison in a factory outside the city. In Pidu District."

"How do you know that?"

"I saw the license plate. The building sign. I saw—" She stopped. "I saw the test subjects. They're using people."

"You can see through the furnace?"

"I don't know. I've never—" She looked at Grandma's body. The furnace was still pulsing, but softer now, like a heartbeat slowing. "Grandma wanted me to know."

Professor Li was pale. "This changes things. If they have a lab, they have records. Names. Formulas. If we can get that evidence to the right people—"

"The right people don't exist. You said it yourself. They own everything."

"Then we find people they don't own."

Liang Yue pulled the sheet back over Grandma's face. She didn't cry. There would be time for tears later, when the work was done.

"I need to get stronger," she said. "The furnace—Grandma taught me the basics, but there's so much I don't know. The manual she left—it's in classical Chinese. It'll take me months to translate."

"Months we don't have."

"Then I need to learn faster."

Professor Li was quiet for a moment. Then he said, "There's someone. A hermit. Lives in the mountains west of Chengdu. He was your grandmother's teacher, back when they were both young."

"Grandma had a teacher?"

"She never told you?"

"She never told me anything." The bitterness in her voice surprised her.

"She was protecting you. The alchemist's path is dangerous. The Zhang family proves that." He pulled out his phone, typing. "I'll send you his location. But I have to warn you—he doesn't take visitors. He doesn't take students. He's been in seclusion for forty years."

"Then I'll make him take me."

The drive to the mountains took three hours. Liang Yue borrowed a car from a classmate, a rusty Honda that rattled on the highway. The furnace sat warm in her dantian, guiding her like a compass.

The road ended at a small village, nothing more than a few houses and a temple. Liang Yue parked and continued on foot, following a trail that wound up into the mist-shrouded peaks.

The air grew thin. Cold. The path was barely visible, overgrown with moss and roots. But the furnace pulled her forward, insistent.

After two hours of climbing, she found it: a stone hut built into the cliff face, its roof covered with solar panels. A garden of herbs grew in terraced beds, their leaves glistening with dew.

An old man sat outside, meditating. He was so still that Liang Yue thought he might be dead. But when she approached, his eyes opened.

They were clear and sharp, the eyes of someone who saw more than what was in front of him.

"You're early," he said.

"Early?"

"Your grandmother said you'd come in summer. It's still spring." He stood, his joints cracking. "But I suppose the situation has changed."

"You know who I am?"

"Liang Yue. Pharmacy student. Inheritor of the Eight-Trigram Furnace." He walked past her, heading toward the hut. "Your grandmother wrote to me. Every month for sixty years. She told me everything."

"She never mentioned you."

"She wouldn't. I was her failure—the one who couldn't complete the Way." He pushed open the door. "Come inside. We have work to do."

The hut was larger inside than it appeared. Shelves lined the walls, filled with jars and scrolls and strange instruments. A cauldron sat in the center, black and ancient, its surface etched with characters that glowed faintly.

"This was my master's furnace," the old man said. "Now it's yours. If you survive."

"Survive what?"

"Training." He turned to face her. "Your grandmother taught you the foundation. But foundation isn't enough. You need to build a house on it. A fortress."

"How long will it take?"

"Six months. Maybe more."

"I don't have six months. The Zhang family—"

"Will kill you regardless of your timeline. The question is whether you die quick or slow." He gestured to the cauldron. "The first lesson: you cannot refine pills until you refine yourself. Your grandmother knew this. But she was too gentle with you."

"What do you mean?"

"She gave you the furnace. She should have given you pain."

The old man moved faster than she could track. His hand closed around her wrist, and suddenly she was on the ground, her arm twisted behind her back, his knee pressing into her spine.

"The first lesson," he said, his voice calm, "is that the furnace is not a gift. It's a burden. Every pill you refine takes a piece of you. Every life you save costs a piece of your own. Your grandmother knew this. She accepted it."

"Let me go."

"When you learn to break free." He released her. "Get up. We start now."

Liang Yue pushed herself up, her arm aching. The furnace pulsed in her dantian, and she felt something new—a resistance, a pressure, like a muscle being tested.

She was going to learn. She was going to get strong.

And then she was going to burn the Zhang family to ash.
