Wu An did not march.
That alone unsettled the court.
The drums did not sound. No banners were raised for a grand campaign. No proclamations of conquest were read aloud to the people. Instead, orders moved quietly—written, sealed, carried at night.
Armies that should have marched south… disappeared east.
Supply wagons moved without banners.
Scouts rode in circles, not lines.
Even the generals did not see the full shape of it.
Only Liao Yun stood before the map and understood.
"You're not attacking Chu," he said.
Wu An did not look up.
"No."
Liao Yun's gaze shifted.
"Then… you're already attacking."
Wu An smiled faintly.
Along the rivers feeding into Jin's canals, something began to change.
At first, it was dismissed.
A grain barge failed to arrive.
Then another.
Then three more.
Storm, they said.
Bad current.
Incompetent crews.
But then came fire.
The first convoy burned at dusk.
No warning. No battle.
Just flames.
Ships anchored along a narrow canal section suddenly ignited—pitch, oil, and something else clinging to the wood like it had been placed there deliberately.
Sailors leapt into the water.
Some did not surface.
Others swore, as they crawled ashore, that they had seen small shadows moving against the current.
Boats.
Low.
Fast.
Gone before the flames even rose high enough to be seen from the watchtower.
Within days, it was no longer coincidence.
Canal locks were sabotaged in the night—gates jammed, mechanisms shattered. Entire sections of water flow slowed or stopped. Grain shipments backed up into long, unmoving lines.
Merchants began shouting.
Officials began writing.
Commanders began panicking.
Because Jin did not understand this kind of war.
Jin controlled movement.
Jin controlled stability.
But this—
This was chaos.
In the Jin court, voices rose quickly.
"This is Liang!"
"They are attacking our supply routes!"
"Where are the fleets? Why are they not intercepting?"
"They are not fleets!" one officer shouted. "They are small boats—too fast, too many, appearing in different places—"
"That is impossible!"
"Then explain the fires!"
By the time explanations began to form—
It was already too late.
The canals had slowed.
Trade had begun to choke.
And with trade—
Came fear.
Back in Liang territory, on a dark stretch of river under no moon, Lin Hai stood at the edge of a narrow war boat, watching the current.
Behind him, smaller vessels waited in silence.
Not ships.
Weapons.
He spoke quietly.
"Too slow."
The helmsman frowned. "My lord, the current—"
"Not the water," Lin Hai said. "The thinking."
He turned.
"We strike faster next time."
He pointed toward the dark.
"They're reacting to where we were."
His voice remained calm.
"So we stop being where we were."
That night, a second wave moved.
Fire ships—small, unmanned, guided by rope and current—were released into a clustered dock where Jin stored reserve grain.
By the time the alarm sounded, the current had already done the work.
The ships collided.
The flames spread.
And the entire dock became a burning mirror on black water.
Lin Hai watched from the distance.
No cheering.
No celebration.
Only observation.
"Good," he said quietly.
Then—
"Again."
Back in Beiliang City, the reports arrived one after another.
Liao Yun placed them before Wu An.
"Jin canals disrupted."
"Grain flow reduced."
"Merchant complaints increasing."
Wu An read them all.
Then set them aside.
"Not enough," he said.
Shen Yue stepped forward.
"You want them to collapse."
"Yes."
Wu An looked at the map.
"Jin doesn't fight war," he said.
"They maintain it."
He tapped the canal routes.
"So we remove maintenance."
Shen Yue nodded.
"And Yan?"
Wu An's gaze shifted east.
"They'll feel it next."
Because trade did not stop at canals.
It flowed outward.
And when canals slowed—
Ports felt it.
Ships arrived late.
Goods failed to move.
Prices rose.
Contracts broke.
And Yan—
The state that lived on trade—
Began to notice.
At the same time—
Something darker began.
Along a tributary near Chu's border, a Liang unit moved prisoners to the water.
Captured sailors.
Bandits.
Convicts.
Their hands were bound.
Their bodies smeared with oil.
The soldiers hesitated.
One of them spoke quietly.
"My lord… this is—"
"Necessary," came the reply.
The order had come from above.
Not shouted.
Not explained.
Just written.
They were placed onto drifting rafts.
Set alight.
And released.
The current carried them.
Toward Chu.
At dawn, Chu patrol ships found them.
Burning.
Floating.
Silent.
A message.
Later that day, another Chu patrol vessel was ambushed.
Not by large ships.
But by shadows.
Small boats striking from different angles.
Hooks.
Fire.
Then gone.
The ship did not sink.
But it burned long enough for everyone to see.
In Chu's capital, the reports arrived together.
Jin's canals disrupted.
Trade slowing.
Yan sending inquiries.
And now—
River disturbances.
Attacks.
Fire.
The ministers spoke over each other.
"He is targeting Jin first!"
"He is cutting the flow!"
"Our patrols are being tested!"
"This is the beginning of an invasion!"
The King of Chu listened.
Then—
Smiled.
Just slightly.
"Good," he said.
The room went silent.
"Now," he continued, "he's finally come into the water."
He stood.
Walked to the map.
Looked at the river routes.
At Jin.
At Liang.
At the shifting lines.
"Prepare the river chains," he said.
"Reinforce the lower crossings."
"Expand patrol range."
His voice remained calm.
Measured.
Certain.
"Let him come deeper."
Because Chu had been waiting.
Not for peace.
For this.
Back in Liang, Wu An stood over the same map.
Now different.
Jin was weakening.
Trade was shaking.
Chu was reacting.
Shen Yue stood beside him.
"You've started it," she said.
Wu An nodded.
"Yes."
Behind them, Lin Hai entered quietly.
He had reports.
New routes.
New ideas.
More ways to burn water.
Wu An did not turn.
"Good work," he said.
Lin Hai bowed.
Wu An's gaze remained on the map.
On the rivers.
On the lines that connected everything.
"This is not a war of ships," Wu An said quietly.
"It's a war of lifelines."
Outside, the rivers still flowed.
But now—
They carried fire.
