Zhang Yu solved the Taishan issue, and then studied the Xuzhou issue.

100000 troops are besieged. This is a big thing. How can Zhang Yu not care.

Zhang Yu's army is not so easy to train.

After thinking for a while, Zhang Yu wrote back to Gao Shun: "believe them, they can block Cao Jun's attack. As long as they last more than ten days, we can take the initiative."

For generals, we should not be soft hearted.

Zhang Yu has planned to bear greater losses. The army has to go through the experience of blood and fire. There is no immortal in war.

Gao Shun has been preparing to mobilize the militia around to defend the city, and then adjusted the number of defenders around.

He's preparing. He can lead the troops out of the city to rescue them if necessary.

Gao Shun collects intelligence from all sides at the same time. Zhang Yu adjusts the intelligence system so that Yanzhou Yuzhou's intelligence will also be sent to Gao Shun.

The situation has become very complicated. It's chaos.

There is a war in the West and two battlefields in the East.

Zhang Yu stayed in Taishan County for three days, leaving the business of this stall to his hands, while he went to the state of Lu.

When Zhang Yu just set out, Ling Cao began to attack and kill Lu Guojun.

Ling Cao finally attacked, and Cao Jun's heart sank. At this time, they had to face Zhang Yu, who was killed on the other side.

Zhang Yu with more than 100000 troops quickly southward, will attack their side rear.

The situation is very critical.

Cao angna has not made any progress. If it goes on like this, the situation will be very unfavorable to them.

When Cao ang and Zhang Yan received the news that they were going to surrender to Zhang Yu, they knew that it was not good.

Jia Xu said: "big young master, we can only attack, or give up, so entangled here, the situation will only be more unfavorable."

"Fight, must fight, I immediately send someone to inform father, let him be ready." Said Cao ang.

Zhang Yu didn't come to rescue the besieged army. In this way, they had no choice but to attack.

With the cooperation of several generals, Cao ang divided into several ways to attack fiercely.

"Kill."

The mighty army advanced up the hill.

There are young generals in several directions.

"In this way, don't try to attack. Order the soldiers and horses in the front line to retreat slowly. Wait for them to come up and give them a heavy blow."

At the foot of the mountain, the army retreated while fighting, and there was not very strong arrow support from above.

Cao ang and Jia Xu watched from a distance.

"They don't even want to use their arrows. They want to stick to it for a long time. I'm afraid it's not easy to fight this battle." Said Cao ang.

Zhang Yu's Army gives people the feeling that it has powerful firepower. If there is support, their soldiers will never spare arrows.

But now they are surrounded, and their arrows are limited, and their attacks are not so fierce.

Cao ang was relieved by the smooth progress of several troops.

However, Jia Xu said: "Mr. big, my subordinates suggest withdrawing some troops, and the follow-up support should not catch up quickly. There is something wrong with this intense attack."

Their soldiers rushed dozens of meters, but the resistance of the other side was not very fierce.

Jia Xu is quite familiar with Zhang Yu's army. He will fight to the death and never give up.

But now they have given up some positions on their own initiative. It's not strange that there is a conspiracy.

Cao ang didn't think much about it, so he sent a messenger.

It's going to take time.

At this time, their army killed more than ten meters.

suddenly

Many people rushed out on the gentle slope of the mountain.

"Kill them, kill them."

"Get out."

An army came out abruptly, charging from top to bottom.

Suddenly attacked, or from the top down.

Cao Jun couldn't resist immediately.

"Shoot the arrow."

A large number of archers also appeared. They stood on the gentle slope and shot down. The attack was just behind Cao Jun.

Many Cao troops could not resist and ran down the mountain. As a result, they were shot down by the arrow rain.

The archers control an area at the foot of the mountain, which is a dead area.

"Don't run, hold on."

"You can't run. Kill it."

Many Cao Jun understand that this run is to leave behind the enemy and die faster.

But there's no way. The impact is too strong.

They can't resist the strong impact.

Cao ang clenched his hands. He knew that the loss was not small.

The army that went up was beaten down again.

They retreated.

After an inventory, more than 4000 people were killed and injured, and a wave of attacks were disintegrated.

Cao Jun took a rest and planned to continue his attack.

But at this time, there was a big fire on the hillside, just over 100 meters away.

Of course, Zhang Yu's army set the fire.

They have cleared out the isolation zone and burned these trees. On the one hand, it is to prevent Cao Jun from killing and igniting.

It's better to burn all these when you can control them.

Burning also cleared the shooting range, making it convenient for archers to attack. In particular, they also prepared a large number of rolling trees on the mountain. These rolling trees and stones are their dependence. With these things, it is difficult for them to rush up.

Cao Ang's face was black. This day is a waste of time. They don't want to attack this day.

There is a big fire on the mountain. It's no use attacking it. They can only watch the play at the foot of the mountain.

It was in the evening that the fires went out.

In this way, a day is wasted.

The next day, a big fire broke out in the upper circle of the mountain, which was also set off by the army above.

They've got a fire barrier, and someone's watching.

However, one day was so wasted. Although the fire went out in the afternoon, that place should still be very hot, so it didn't go at all.

Cao ang was in a bad mood below.

They have wasted two days. They don't have so much time to waste. Now they are fighting for time.

On the third day, there was no fire.

But they began to cut trees. Some of the big trees were burned bare, leaving only one thick trunk.

They are just cutting down these big trees, as if ignoring Cao Jun at the foot of the mountain.

Cao ang wanted to attack, but he didn't know where to start.

"Sir, they have dug a lot of places for Tibetan soldiers on the mountain. If they attack rashly, they may lose a lot." Said Cao ang.

Cao Ang's memory is still fresh. At this time, he did not know how many traps were hidden in the mountain.

It's very bad for them to drag on day by day.

"Young master, we have to move forward slowly and compete with them a little bit. In this way, we will lose a lot." Jia Xu said.

Cao ang had no choice but to fight hard, so they mobilized a large number of shields.

Gather all the shields of the army and arrange more archers at the same time.

Cao's army slowly ascended the mountain in a scattered formation.

"That's it. You can't attack in ten days." A few young players judge after evaluation said.

A few young generals are not afraid at this time. After analyzing, they also judge the current situation.
