Wu An is winning.
But only barely.
Every map in the command tent shows the same truth from a different angle. Liang banners now sit deeper inside Zhou territory than any army in a generation. Several cities have surrendered without major bloodshed. Roads and crossings once controlled by Zhou are now held by Black Tiger detachments and newly raised provincial troops.
On paper, it looks like momentum.
On paper, it looks like victory.
But paper does not show grain.
And grain is the real war now.
The quartermasters arrive at night because they do not want the soldiers to hear the numbers.
But Wu An insists they speak in front of him anyway.
"How long?" he asks.
The chief quartermaster kneels, head lowered.
"If we continue full operations, six weeks."
Liao Yun exhales slowly.
"And half rations?"
"Ten weeks. Maybe twelve."
"And if we stop advancing?"
The quartermaster hesitates.
"If we stop moving, we must still feed the army. The land around us is already stripped by Zhou before we arrived. Even if we buy grain, there is not enough in these provinces to feed one hundred thousand men."
That is the truth.
Zhou has been burning and emptying the land for months.
General Pei's strategy is now clear.
He is not trying to defeat Wu An in one battle.
He is trying to starve him.
Wu An walks through the captured city the next morning without escort.
Markets are open. People bow when they see him. Some even kneel. Word has spread across the province that Liang soldiers pay for grain, that Liang law punishes its own men, that Liang does not massacre cities that surrender.
To these people, Wu An is not a monster.
He is a liberator.
That is the problem.
Because liberators cannot steal food from the people they claim to free.
If he takes their grain by force, the propaganda collapses.
If the propaganda collapses, Zhou's people resist.
If Zhou's people resist, the war becomes impossible to win.
So Wu An has trapped himself with his own mercy.
He stands in the market square watching civilians trade the last of their winter vegetables and dried grain cakes.
Shen Yue joins him quietly.
"You could take it," she says.
"Yes."
"You could say it is for the war."
"Yes."
"And you would still win some battles."
"Yes."
"But we would lose the war," she finishes.
Wu An does not answer.
Because that is exactly the calculation.
General Pei begins the second phase of his war.
He stops trying to push Wu An back immediately.
Instead, Zhou armies fall back slowly in front of Liang advances, destroying grain stores, moving livestock, evacuating civilians, collapsing irrigation systems, poisoning wells.
Behind Wu An — Zhou cavalry raids continue cutting supply wagons coming from Liang territory.
In front of Wu An — the land is empty.
Pei is creating a box.
Not a wall.
A famine.
Zhou's vast resources finally begin to show their true weight.
New armies rotate in from interior provinces.
Fresh horses replace exhausted ones.
Canal barges bring grain south to feed Zhou armies while the northern provinces starve to deny Liang food.
It is brutal.
It is effective.
It is empire-level warfare.
General Pei explains it simply to his officers:
"We do not need to defeat Wu An's army," he says.
"We only need to make sure it cannot eat."
One officer frowns.
"But the Emperor wants victory."
Pei looks at the map.
"This is victory."
He points at Liang's deep position inside Zhou territory.
"He is too far from home."
He points at the burned provinces.
"He cannot live off the land."
He points at the Zhou interior supply lines.
"We can."
Then he says quietly:
"War is not always won by the sword. Sometimes it is won by the stomach."
Weeks pass.
Liang soldiers begin to feel it first in their legs.
Then in their tempers.
Then in their sleep.
Rations are cut again.
Then again.
Horse meat appears in the stew.
Then mule meat.
Then thin grain porridge.
Black Tiger battalions remain disciplined.
Newer units begin to complain.
One night, two soldiers fight over a stolen bag of dried beans.
One of them dies with a knife in his throat before the guards arrive.
Liao Yun reports it the next morning.
"It's starting," he says quietly.
Wu An nods.
"Yes."
"This is what Pei wants."
"Yes."
"He wants us to rot out here."
Wu An looks at the map.
"Yes."
Another city offers surrender.
The magistrate kneels and offers grain stores if Liang promises protection.
Liao Yun looks at Wu An carefully.
"If we take their grain, we can feed the army another month."
Wu An looks at the kneeling magistrate, then at the civilians watching from the walls.
If he takes the grain, the army survives longer.
If he takes the grain, the people starve.
If the people starve, Liang becomes Zhou.
If Liang becomes Zhou, the people resist.
If the people resist, Liang dies.
Wu An speaks slowly.
"We take half," he says.
"Leave the rest."
Liao Yun hesitates.
"That may not be enough."
"It has to be."
Wu An looks at the city.
"If we become thieves, we are finished."
That night Shen Yue finds him awake, staring at the map but not seeing it.
"You're afraid," she says quietly.
Wu An does not deny it.
"Yes."
"Of Pei?"
"No."
"Of the Zhou Emperor?"
"No."
"Then what?"
Wu An's voice is very quiet.
"I am afraid that I can win every battle and still lose the war."
That is the first time he has said it aloud.
Shen Yue sits beside him.
"Then what do we do?"
Wu An looks at the map again.
At the Zhou armies.
At the burned land.
At his own stretched supply lines.
At the deep position he fought so hard to reach — which is now a trap.
General Pei is not trying to defeat him.
He is waiting for him to run out of food.
Waiting for hunger to do what armies could not.
Wu An finally speaks.
"Then we stop fighting the army."
Shen Yue frowns.
"Then what do we fight?"
Wu An's eyes are cold again.
"We fight the empire."
He places his finger not on the Zhou army.
Not on the river.
Not on the front line.
He places it deep inside Zhou territory.
On the canals.
On the granaries.
On the transport roads.
On the tax routes.
On the places that feed the armies.
"If we starve," Wu An says quietly, "we die."
"If Zhou starves…"
He does not finish the sentence.
He does not need to.
Because that is the next escalation.
Not battlefield against battlefield.
Nation against nation.
Hunger against hunger.
And when wars reach that stage—
They do not end cleanly.
They end with something breaking.
