Chapter 4: The Pipeline That Held a Dynasty
~1.2k words · 2026-06-22
The Heavenly Domain's central plaza looked like a construction site after a monsoon.
Liu Yang stood ankle-deep in something that shimmered like liquid starlight but smelled like a blocked sewer. His steel-toed boots—salvaged from the maintenance shed he'd found on day three—were already corroding at the seams. Three days of work, and all he had to show for it was a schematic that looked like a spiderweb drawn by a drunk, a pile of qi-steel beams that kept trying to float away, and a headache that pulsed behind his left eye like a second heartbeat.
"This is impossible," he muttered.
Old Man Feng appeared beside him, carrying a teapot that steamed with something brown and vaguely medicinal. The celestial carpenter had become Liu Yang's unofficial shadow over the past week—part translator, part supplier, part skeptic who refused to admit he was impressed.
"The pipeline runs through seventeen cloud formations," Feng said, pouring tea into a cup that materialized from his sleeve. "Each formation has different density. Different pressure. Different—"
"I know." Liu Yang tapped his calculator. The numbers didn't lie. The qi flow through the Heavenly Domain was designed like a garden hose—straight lines, sharp turns, no consideration for pressure drop or structural load. The immortals had been patching leaks for centuries instead of redesigning the entire system.
And the leaks were getting worse.
Yesterday, a maintenance worker had nearly fallen through a cloud floor that had been weakened by qi erosion. The worker didn't care—he was immortal, after all—but Liu Yang had grabbed his arm and pulled him back. The look on the man's face wasn't gratitude. It was confusion. Like no one had ever bothered to save him before.
"That's the problem," Liu Yang said, taking the tea. He didn't drink it. "You're all infinite. So nothing matters. You patch a leak, it breaks again, you patch it again. For eight hundred years."
Feng's eyes narrowed. "You say this like it's a flaw."
"It's a design failure."
The old man laughed, but there was no humor in it. "You've been here one week, Engineer. You don't know what you're talking about."
"Then show me the main distribution node."
Feng's teacup stopped halfway to his lips.
"Nowhere," Feng said. Too quickly.
"That's what I thought." Liu Yang folded his schematic and tucked it into his pocket. "I need to see where the qi comes from. The source. Every pipeline, every leak, every repair order for the last century—I need access."
"You're asking to see the Celestial Vault."
"Is that what you call the filing room?"
Feng set down his tea. The steam curled upward, forming shapes that looked almost like characters before dissolving. "The Vault is not a filing room. It's the heart of the Heavenly Domain. The Jade Emperor's private archive. No one enters without his permission."
"Then get me his permission."
"You don't ask for things here, Engineer. You wait. You cultivate patience. You—"
"I don't have eight hundred years."
Feng's jaw tightened. For a moment, Liu Yang thought the old man might strike him. Instead, Feng reached into his robe and pulled out a jade token, green as spring leaves, etched with characters that glowed faintly.
"I was the chief engineer before you," Feng said quietly. "Three hundred years ago. I designed the current pipeline system."
Liu Yang stared at him.
"You know it's broken," Feng continued. "But you don't know why. You think it's old age. Poor maintenance. Carelessness." He pressed the token into Liu Yang's hand. "It's none of those things. It was built to fail."
The token was warm. Alive. It pulsed with a rhythm that matched Liu Yang's own heartbeat.
"Who built it?" Liu Yang asked.
Feng looked over his shoulder. The plaza was empty except for a few maintenance workers hauling qi-steel beams across the cloud bridge. No one was watching. But Feng lowered his voice anyway.
"The previous Jade Emperor. The one who disappeared."
"He disappeared?"
"Vanished. No trace. No explanation. One day he was here, the next—" Feng snapped his fingers. "Gone. And the system he left behind? It's been corroding from the inside ever since."
Liu Yang turned the token over in his hands. The characters shifted, rearranging themselves into a map. Pathways. Junctions. A central point marked with a symbol he didn't recognize.
"What's that?" he asked, pointing.
Feng's face went pale. He grabbed Liu Yang's wrist, almost crushing it. "Don't go there. Don't even think about it."
"Why?"
"Because that's where the first emperor went. And whatever took him is still waiting."

The Celestial Vault wasn't a vault.
It was a library that stretched into infinity. Shelves made of jade and cloud-stone rose so high Liu Yang couldn't see the ceiling. Scrolls floated between them like fish in a slow current, brushing against his shoulders as he walked. The air smelled of old paper, ozone, and something else—something metallic, like blood.
Feng had refused to come with him. "I've given you the key," he'd said. "The rest is your choice."
So Liu Yang had chosen.
He walked for what felt like hours, following the map that pulsed in his palm. The token guided him through corridors that shifted and rearranged themselves, through rooms filled with artifacts that hummed with power, past doors that whispered his name in voices he didn't recognize.
He didn't stop. He didn't look back.
The central chamber was smaller than he'd expected. A circular room, no more than twenty feet across, with a single pedestal in the center. On the pedestal sat a scroll, bound with red silk.
And on the floor around the pedestal, someone had drawn a circle of characters. Hundreds of them. Thousands. They spiraled outward in patterns that hurt to look at, like staring into the sun.
Liu Yang stepped inside.
The characters flared. Light flooded the room, so bright he had to shield his eyes. The scroll on the pedestal unrolled by itself, revealing lines of text that glowed like molten gold.
He read the first line.
*To the one who finds this: you have three days.*
His blood went cold.
*The pipeline you seek to repair is not broken. It is a cage. Every leak you fix tightens the chains. Every patch you apply strengthens the prison. The qi that flows through the Heavenly Domain is not power. It is a leash.*
Below the text, a diagram. The pipeline system he'd been studying for three days suddenly made sense—but not as infrastructure. As a binding array. Each pipe, each junction, each maintenance hatch formed a symbol that looped back on itself, trapping something in the center.
Something at the node marked on Feng's map.
*The previous Jade Emperor built this to contain a creature he could not kill. The creature has been feeding on the qi of the Heavenly Domain for eight hundred years. It grows stronger with every repair. It grows hungrier with every patch.*
*You are the engineer who will either save this realm or doom it.*
*Choose wisely.*
Liu Yang's hand trembled. The token in his palm went cold.
Behind him, the door to the chamber slammed shut.
The characters on the floor began to move, crawling toward his feet like living things.
And a voice—low, ancient, amused—spoke from the shadows.
"Finally. Someone who knows how to read."
Liu Yang turned.
The creature sitting in the corner of the room had been watching him the entire time.
