Dawn was a grey smear. Shan Jian stood at the edge of the floodwater, west of the shrine hill, staring at the drowned ridge. It was exactly as Duan Jin had described: a gentle saddle of land between two rocky spurs, now a still, leaden lake. Trees emerged from the water like the hairs on a drowned man’s head.
Ling Zhi stood beside him, a silent, disapproving shadow. Behind them, Duan Jin had gathered a ragged crew of fifteen men and a few sturdy women. They held axes, adzes, and ropes coiled over their shoulders. Their faces were a mix of skepticism, resentment, and a fragile, desperate hope. Hope was the most dangerous tool of all.
“The blockage,” Shan Jian said, pointing to the southern end of the saddle where the land dipped. “The water should drain there, into the old creek bed that feeds the river. Something is plugged.”
“We know that, Highness,” a woman said, her voice tired. “The earth slid, two moons ago. After the big rains. Buried the outlet.”
“Then we dig it out,” Shan Jian said.
A man scoffed. “With what? Our hands? The mud there is like sucking glue. You step in, you don’t come out.”
Liquefaction risk, the engineer’s mind supplied. Saturated, fine-grained sediment loses shear strength.
“We don’t step in,” Shan Jian said. “We work from the edges. We use the water against itself.” He knelt, ignoring the mud on his fine, ruined robes. With a stick, he began to draw in the wet earth.
The crowd edged closer, despite themselves.
“See here,” he said, his voice taking on the cadence of a site foreman. “The slide material is here.” He drew a mound. “Water is here.” He shaded an area. “We cannot move the mountain of mud. But we can let the water move it for us. We dig a pilot channel here, on the high side.” He sketched a narrow trench angling from the deeper part of the new lake toward the blockage. “We control the flow. Use it to erode and carry the loose material away, bit by bit. We build a temporary cofferdam of brush and stone here to protect our working area.”
It was simple. Elegant. It was the principle behind a hydraulic mining jet, scaled down to sticks and mud.
Duan Jin crouched, studying the crude diagram. His craftsman’s mind saw the logic. “The current will do the hard work. We just guide it.”
“Yes. But we must be precise. The force must be focused, not wild. We need to build a guide channel, reinforced.” Shan Jian’s mind raced. Materials? They had brush, stone, and the doomed timber from the ridge itself once the water lowered. “We start by cutting brush and gathering loose stone from the spurs. We build the guide walls first.”
He stood, assigning tasks with an authority that felt both alien and instinctive. Chen Wei had directed crews of hundreds. This was no different. Just… more mortal.
The work began, slow and clumsy with hunger and cold. But it was work. Purpose was a kind of warmth. Shan Jian worked alongside them, his soft hands blistering as he hauled brush. He watched, learned, adjusted. These people knew the weight of stone, the bend of wood, the way mud behaved. Their knowledge was tactile, experiential. His was theoretical. He needed both.
By midday, they had a ragged, V-shaped channel of bundled brush and rock leading toward the slide. The water within it flowed faster, already scouring the bottom.
“Now,” Shan Jian said, his heart pounding with a familiar, terrifying thrill—the moment of application. “We breach the final berm into the deeper pool. Carefully.”
Two men with digging sticks began to pry at the earthen wall. Water trickled, then gushed. The focused stream hit the face of the landslide with a solid slap.
And nothing happened.
The water swirled, dissipated. The mud wall stood impassive. Minutes passed. The crew’s fragile hope began to curdle into confirmed despair. Sneers returned.
“It’s too solid,” someone muttered. “Waste of time.”
Flash.
The testing lab. A scale model of the Aurora Tower’s foundation. Simulated groundwater pressure. The model held. The contractor smiled. “See? Told you it was fine.” The model was wrong. It was always too clean.
This was a model, too. And it was failing.
Think. The water pressure was insufficient. They needed more head, more volume. But the lake level was fixed. His eyes scanned the ridge, the tools, the tired people. Leverage. We need leverage.
His gaze fell on a long, straight pine sapling, cut for a lever. An idea, absurd and brilliant, struck him.
“Duan Jin! That lever—hollow it out. Fast as you can.”
The smith stared. “Hollow it? Why?”
“Just do it! As long as you can make it, and as straight as possible. Leave one end closed.” He turned to others. “Gather every piece of hide, every waxed cloth, anything that can hold water and be sewn into a bag!”
Confusion reigned, but the sharp urgency in his voice spurred movement. Duan Jin took an adze and began, with brutal efficiency, to gouge out the heartwood of the six-meter sapling, creating a rough, narrow tube.
Shan Jian’s mind was alight. A hydraulic ram. A primitive, stupidly simple hydraulic ram. Use the kinetic energy of a falling mass of water to create a pressure pulse. They couldn’t raise the whole lake. But they could raise a small volume, and drop it with focused force.
While Duan Jin worked, Shan Jian directed the sewing of a large, tough leather bag from spare waterskins and a piece of oiled tent cloth. They attached it with ropes to a sturdy tripod made of logs, positioned directly over their pilot channel, just upstream of the breach.
The crew watched as if he were performing magic. Ling Zhi watched, her expression unreadable.
Finally, Duan Jin handed him the hollowed log, now a crude pipe. One end was mostly closed, with a small hole. Shan Jian positioned it, angling the open end into their pilot channel’s flow. The closed end he aimed directly at the face of the mud slide, bracing it with rocks.
“Now, fill the bag!”
They used buckets to pour water from the lake into the suspended leather bag. It swelled, heavy and pendulous.
“Stand clear!” Shan Jian yelled. He took a knife and, with a s***h, cut the primary rope holding the bag.
The bag dropped. A huge volume of water crashed down the hollow log. The physics were brutal and beautiful. The water column, forced through the constriction at the bottom, accelerated. It jetted from the small hole in the closed end not as a flow, but as a concentrated, high-pressure pulse.
THUMP.
The water jet struck the mudface like a giant’s fist. A chunk of saturated earth the size of a barrel sheared away and dissolved into the current.
A collective gasp went up.
“Again!” Shan Jian commanded, already helping to re-raise the bag.
They repeated it. THUMP. Another chunk vanished. THUMP. A c***k appeared in the slide. The focused, hammer-blow pulses did what diffuse water pressure could not. They were literally punching a hole through the blockage.
On the sixth pulse, with a deep, sucking groan, the slide yielded. The pent-up water of the entire ridge lake found the new weakness. It wasn’t a gentle trickle. It was a roar.
The engineered pilot channel held, directing the unleashed torrent. A brown, furious river erupted from the saddle, scouring the slide material before it, carving a deepening channel down toward the old creek bed. The water level in the ridge lake began to fall, visibly. Inches, then feet.
Silence fell, broken only by the roar of the liberated water. The crew stood, stunned, coated in mud and spray, watching the land reappear. First the tops of the drowned trees, then their trunks, rising like ghosts from the retreating tide.
Duan Jin turned to Shan Jian, his face a mask of mud and awe. He looked at the crude hollow log, the cut ropes, the simple tripod. “What… what do you call that?”
Shan Jian, breathing heavily, tasted the ghost of copper—the taste of adrenaline from a crisis averted. He almost said ‘hydraulic ram.’ He stopped himself. “A… Water-Dragon’s Fist,” he said, the name coming from the prince’s memory of myth.
Duan Jin repeated it, reverent. “The Water-Dragon’s Fist.”
It was in that moment of triumph, as the sun broke weakly through the clouds, glinting on the freed water, that the Ledger fully awoke.

The data stream was cool, clear, and overwhelming. It wasn’t just reporting success; it was reporting the hidden success. The land wasn’t just draining; it was reacting.
Ling Zhi stepped forward, not looking at the receding water, but at the muddy channel where it fled. She knelt, placed a hand in the flowing current, and closed her eyes. When she opened them, they were wide. “It’s… cold. Not with winter. With… memory. It remembers its path.” She looked at Shan Jian, her earlier disapproval shattered into wonder and deep, unsettling confusion. “What did you do?”
He didn’t have an answer. He could only see the numbers, feel the ghost of the water-ram’s thump in his bones, and hear the Ledger’s silent, analytical hum in the core of his mind. It was awake. And it was hungry for more.
