To attack Xuchang's army from Xuzhou was just a feint.

Although it was a feint, they were well prepared, with a lot of siege equipment and enough logistics.

This is to make Xu Chang dare not ignore it.

But they even mobilized the surrounding troops and surrounded them by force.

One hundred thousand people were besieged in the mountains.

There are several small generals leading the army. As it is expected that there will not be too strong fighting, they will be led by small generals.

Although he is a young general, he has played many battles.

Cao Jun built layers of defense at the foot of the mountain, trying to trap them in the mountains.

Several young generals led their troops to make a surprise attack respectively. After fighting for a day, both sides lost a lot and failed to break through.

In the night, a few young generals were in a meeting.

"Cao Junzhong, they can't fight for a while. They made it clear that they wanted to trap us to death on this mountain." A young general said.

"With 200000 troops and a large number of archers, they besieged this area to death. It's really hard for them to rush out."

"What I fear most is that there is not much water in the mountains, or when conditions are ripe, they set fire to them."

"We must plan for a long-term battle. Even if the rescue is not in time, we can hold fast here and make Cao Jun passive."

They feigned an attack on Xuchang in order to contain the enemy's troops. Now they are able to contain 200000 troops.

We'll do some research to make sure.

"I remember my lord taught us that we only need to dig more isolation zones for fire prevention. In addition, for water sources, we need to dig more wells with springs on them. There should be a lot of underground water."

Several people have studied in Colleges and universities, and they have learned a lot about natural science, which can be used at this time.

They set out to attack the city with a lot of tools.

In order to fill the trench, this sack and shovel are necessary.

In order to build siege equipment, they also brought many logging tools.

After a night of deliberation, they began to act.

Several trenches were dug in the mountains, and many trees were cut down, causing bunkers and rolling trees, and preventing the enemy from setting fire.

At the same time, they also dug wells and pools, which looked like they were going to fight for a long time.

A few young generals are smart. They judge that if Cao Jun is just to besiege them, it doesn't matter. He will spend time with them.

If you want to eliminate them, you have to be prepared.

Cao ang really wanted to set fire. At the beginning, he wanted to set fire at the foot of the mountain, but Zhang Yu's troops had a defense at the foot of the mountain, so they didn't succeed.

Of course, a lot of protection has been done for the 100000 troops camping.

After a few young players understand the situation, they feel at ease.

As the night passed, the young generals began to act separately. A few people set up defences at the foot of the mountain, and a few people set up things on the mountain.

At this time, they are faced with a more important problem, that is, how to report the situation here to Gao Shun.

Let Gao Shun know their situation, and then arrange things, and he won't be attacked by the enemy.

There is no good way, but I believe Xuzhou will not easily rescue, will find out the situation.

When a new day came, the environment at night was unknown, and Cao ang did not dare to attack rashly.

When it was day, they suddenly found that there were many fewer trees on the mountain.

The trees are still decreasing because they can see big trees falling.

"I'm afraid fire attack is out of the question. Maybe they are my classmates in Jiangdong University, and they know how to get the isolation belt." After looking at it for a while, Cao ang figured out what the army on the mountain was doing.

If they could not attack by fire, they would attack by force. At this time, Cao ang could not judge whether the soldiers on the mountain had much food and water.

"Young master, we will besiege them for two days. If they are in a hurry, they will take the initiative to break through the encirclement. There will be no movement for two days. I'm afraid it will be difficult to fight this battle." Jia Xu said.

Cao ang said, "OK, but we need to send more people to prevent Zhang Yu's army from attacking us."

The fear of being attacked is certain.

Gao Shun soon knew the situation, but he did not go to rescue, but further strengthen the defense of xiapi City, while sending a message to Zhang Yu.

Even if all the 100000 troops are lost, Gao Shun knows that there can't be an accident in xiapi city.

If there is an accident in xiapi City, the whole Xuzhou will be in danger.

Gao Shun sent a lot of people out to investigate the situation.

According to his estimation, the army has brought grain and grass for a month, and it will be no problem to stick to it for a month. When they have finished their own arrangements, they will send people out to meet them.

Cao ang besieged them for two days. Within two days, Zhang Yu's army was strengthening defense for a while, digging a lot of trenches and isolation belts, but there was no sign of breaking through.

Cao ang was very disappointed. This battle was meant to be a sneak attack, but it was very difficult for them to camp on the mountain at night.

"Young master, we can only attack like this, but we may lose a lot." Jia Xu said.

In the face of Zhang Yu's army, Jia Xu has no choice.

Their attack on Zhang Yu's army is to break Zhang Yu's offensive and make a major loophole in their Xuzhou direction.

However, if he can't break through the army quickly, Zhang Yu can arrange it calmly.

When Zhang Yu received the message, it was a few days later. At this time, Zhang Yu had discussed with Zhang Yan and began to attack Cao Jun.

More than 40000 Cao Jun suffered. After they were found, with Zhang Yan's cooperation, they were not surrounded by Zhang Yu.

Surrounded in the mountains, the Cao army's combat effectiveness is less than Zhang Yu's army. As a result, they can't even beat the Yellow scarves.

He persisted for two days and was wiped out in the mountains.

Finally, Zhang Yu completely conquered Taishan county.

However, Zhang Yu was also entangled at this time, and hundreds of thousands of yellow scarves were not so easy to deal with.

Zhang Yu couldn't leave in a short time.

However, Cao Jun of Lu state in Yuzhou had a hard time. Taishan county was beaten down so quickly.

They expect that it will take ten days and a half months, or even one or two months, to solve Zhang Yu's problem. If the South annihilates 100000 Zhang Yu's troops by then, it will be able to turn over.

As a result, Zhang Yu solved the problem first.

"Zhang Yan, if you want to continue to lead the army, you can have an army of 50000. Zhang Yu will treat you equally and will not break his promise." After incorporating the army of Huang Jin, Zhang Yu said to Zhang Yan.

Zhang Yu gives them two choices. One is to live a rich life. Zhang Yu gives them money, land and luxury houses.

One is to continue to lead the troops in the war.

Zhang Yan knelt down on one knee with her fists in her arms and said, "please accept me. My subordinates are willing to continue to lead the army. I'm afraid it's not suitable for them to leave the army."

"OK, but I can't let you take the original army. Please forgive me. I'll train with your army for two months, and then reorganize an army for you after two months." Zhang Yu said.

Zhang Yu's army has undergone unified training. Without unified training, the army simply can't understand their way of fighting, and there will be big problems when they cooperate. Zhang Yu must retrain and reorganize Huang Jin.
