They called it the Coalition to Punish the Usurper.
The name spread across the land before the army even began to move. Proclamations were nailed to city gates, read aloud in marketplaces, carried by riders from province to province.
"Wu An, the butcher of Zhongjing, murderer of the Son of Heaven, has stolen the Mandate.
All righteous lords under heaven shall unite to punish the usurper and restore order."
It sounded righteous.
It sounded just.
It sounded like history had already decided Wu An was the villain.
But righteousness still required an army.
And the army they gathered was enormous.
Wei sent its heavy infantry and grain convoys.
Chu sent river troops and engineers.
Jin sent supply officers and canal fleets to maintain logistics.
General Pei commanded the northern cavalry and the core Zhou veterans.
When the armies merged, the coalition army stretched for miles — banners of different colors, different symbols, different commanders, all marching in the same direction.
South.
Toward Zhongjing.
In the capital, the news arrived quickly.
Liao Yun did not look surprised when he read the report. He looked tired.
"They are coming faster than expected," he said.
Wu An studied the map. "How many?"
"More than two hundred thousand if they fully unite. Maybe more if others join later."
That was twice Wu An's army.
Maybe more.
If Zhongjing was besieged again, the city might hold.
But the consequences would be fatal.
Trade would stop again.
The eastern recovery would stop.
The army would be trapped defending instead of expanding.
The other states — Yan, Zhao, Han, Western Zhou — would watch and wait until Liang and the coalition destroyed each other.
If Wu An stayed in Zhongjing and defended, he might survive.
But he would never conquer the rest of Zhou.
And if he did not conquer Zhou, Zhou would eventually conquer him.
This was not a battle for a city.
This was a battle for time.
And Wu An understood something the other rulers did not.
Whoever controls the pace of the war controls the outcome of the war.
If he waited, he lost.
If he defended, he lost slowly.
So he chose the only option left.
He would attack.
The court exploded in protest when the order was announced.
"Attack?" a minister shouted. "They outnumber us two to one!"
"If we leave the capital, Zhongjing will be exposed!"
"If we lose this battle, Liang is finished!"
Wu An listened to all of them, then asked one question:
"If we do not fight this battle, when do we win?"
No one answered.
Because everyone knew the answer.
They never would.
That night, Wu An met with Liao Yun and Shen Yue alone.
"We cannot let them unite," Wu An said. "If Wei, Chu, Jin, and Pei combine their forces completely, we cannot defeat them in a single battle."
"So we don't fight them as one army," Liao Yun said quietly.
Wu An looked at him. "Exactly."
He placed several stones on the map — one for each coalition army.
"They are allies," Wu An said. "But they do not trust each other. They march together, but they camp separately. Their supply lines are separate. Their commanders are separate."
Shen Yue understood first.
"We don't fight the coalition," she said.
"We destroy it before it becomes a coalition," Wu An replied.
The plan was simple.
And completely insane.
Wu An would march out of Zhongjing with almost his entire field army.
He would move fast, avoid the main coalition force, and strike one army — not all of them — before the others could reinforce.
A sudden strike.
Annihilate one faction.
Disappear.
Then strike another.
Turn two hundred thousand men into five separate armies that were too afraid to move alone and too distrustful to move together.
Liao Yun looked at the plan for a long time.
"If we fail," he said, "we lose everything in one battle."
Wu An nodded.
"Yes."
"And if we succeed?"
Wu An looked north, toward the marching banners of the coalition.
"If we succeed," he said quietly, "they will never trust each other again."
A week later, the gates of Zhongjing opened.
One hundred thousand Liang soldiers marched out — artillery, muskets, cavalry, supply wagons — moving fast, moving light, moving north.
Not to defend.
Not to retreat.
To hunt.
Far ahead, the coalition armies were still marching, still organizing, still arguing over command, over supply priority, over who would lead the final assault on Zhongjing and take the glory.
General Pei, however, did not celebrate.
He studied the reports again and again.
Then he asked a question that made his officers uneasy.
"Where is Wu An?"
No one had seen Liang's main army.
No one had reported Zhongjing preparing for a siege.
No one had seen Wu An behind the walls.
Which meant only one thing.
Pei looked at the map and felt a chill run down his spine.
"He's not in the city," Pei said quietly.
One of his officers laughed nervously. "Then he must be retreating."
Pei shook his head slowly.
"No," he said.
"He's coming."
Somewhere between Zhongjing and the marching coalition armies, Wu An rode at the front of his army, the wind cold against his face, the road dark ahead.
Behind him marched one hundred thousand men.
Ahead of him marched an army twice his size.
Shen Yue rode beside him and asked quietly:
"Are we gambling everything again?"
Wu An did not slow his horse.
"We were dead the moment they formed the alliance," he said.
He looked toward the north, where the banners of Wei, Chu, Jin, and Zhou were somewhere beyond the hills.
"This is not a gamble," Wu An said.
"This is survival."
Then he gave the order.
"Move faster," he said.
"Before the coalition becomes an army."
