Zhang Yu is not afraid of being surrounded. He has grain and grass in his hand and an army. He is not afraid at all.

Order the army to set up the defense immediately.

The soldiers cut down the big trees around them and made them into defensive tools.

Even resisting horses is a lot.

Not far away, Cao's army had caught up and surrounded the periphery, but because of the night, Cao's army did not dare to attack.

It's not so easy for Zhang Yu's troops to fight. If they are not careful, they may suffer a big loss.

Cao Cao led more than 300000 troops, and nearly 400000 troops were outside.

He has concentrated most of the troops in Yanzhou and Yuzhou, and also mobilized some troops from Luoyang.

If you don't block Zhang Yu's attack, you will lose sooner or later, and Cao Cao has already pressed on.

"Lord, let your subordinates bring tens of thousands of troops to explore the situation." Xu Chu asked for instructions and wanted to lead the troops to test.

Cao Cao shook his head and refused to say: "it's dark. Zhang Yu must have an ambush. It's better to be safe after dawn."

Zhang Yu did have an ambush, and a large number of archers had been located before dark.

If Cao Jun attacked, he would have suffered a great loss.

Zhang Yu's side, tense defense.

After half a busy night, Zhang Yu cut down many big trees around him.

Cut down the big trees to prevent the enemy from setting fire. At the same time, the wood can be used as an obstacle and a defense tool.

At daybreak, Cao Jun saw that Zhang Yu had built a preliminary defense.

"Lord, Zhang Yu has built a defense, but they have too many troops and lack of food and grass. As long as we trap them for a month, we can win easily."

The truth is this truth. Cao Cao also understands that the most important thing is that they should have one month.

Four hundred thousand troops were transferred by Cao Cao, but there were not many troops from other directions. If Zhang Yu could not be captured quickly, even if Zhang Yu was killed here, they would lose in the end.

Cao Cao's face is not very good, did not surround Zhang Yu, but let Zhang Yu escape here, also robbed his own batch of food and grass.

"Lord, let me have a try." Cao Ren asked to fight.

This time, it was because of Cao Ren's mistake that Zhang Yu was given a chance.

Cao Cao nodded and said, "OK, I'll give you 30000 troops. Go and test them. If you can't do something, return immediately."

Cao Ren took the order and left.

The depression is very big. Zhang Yu divides it into several parts to defend it. In front of it are sword shield soldiers, long spearmen and cavalry. At the end, Zhang Yu doesn't want them to fight.

There are also many archers on the slope.

Behind is a mountain, Zhang Yu sent 20000 people to defend on the mountain.

Cao Ren, with 30000 people, rushed up.

Zhang Yu's side did not respond.

The archers on both sides lead without firing.

Cao Ren with the army killed up, and so close, face to face, the archer did not issue an arrow.

"Kill."

The sword and shield soldiers come out and fight with Cao Ren.

The two armies were fighting in front of the col.

The fighting was fierce and the soldiers on both sides were fearless of death.

However, the fighting area between the two sides is relatively narrow, and there are only two or three thousand troops fighting at the same time.

Cao Ren's army pays great attention to defense. After all, the archers on both sides are on the high ground and may attack at any time, but they have been fighting for a long time, and the archers have not attacked.

"Step back. There's no point in fighting." Said Cao Cao.

Cao Cao reluctantly ordered to withdraw.

On one side, Xu Chu was very unconvinced and said in a loud voice: "Lord, let me go down and knock on Zhang Yu's tortoise shell."

Cao Cao shakes his head and laughs bitterly. It's not so simple.

Zhang Yu wants to defend and doesn't want to attack.

The archers on both sides didn't shoot.

The fighting area is so small that even if it is filled with human life, it will not work for ten days and a half months.

"Zhang Yu is counting on Wang's weakness. If he can't attack here in a short time, it must be us who will fail." Cao Cao said in a low voice.

Zhang Yu's refusal to let archers attack is a deterrent.

And they don't carry a lot of arrows.

Cao Cao observed there for a day, but there was no good way.

Zhang Yu and his family continued to strengthen their defense with soil, stone and wood.

"Mud all the wood and make it thicker." Zhang Yu walked around the mountain depression to check the soldiers' defense.

Mud the wood to prevent the enemy from setting fire.

Zhang Yu checked around, then sat on the high ground and looked down.

In the distance, Cao's troops were encamped at different levels.

"There are many capable men in the Cao army. This time, I was almost surrounded. Once I was surrounded, I would be passive."

Zhang Yu is also glad that he found out early, and suddenly attacked, so that Cao Ren was unprepared, so that he had the present situation.

Zhang Yu after analysis, Gao Shun with Zhang Liao, Zhao Yun know the situation, will be a fierce attack.

Cao's army dispatched most of its troops. Once they were not prevented, Cao's army would face a great collapse.

After thinking for a while, Cheng Yu said, "Lord, the situation is very unfavorable for us in this war. We should plan ahead. "

"What are you going to do?" Cao Cao began to think.

Now it's too late to change the layout. Can Cao Cao withdraw his troops to support the other two directions.

It's impossible. Zhang Yu is here. He has nearly 200000 troops. He can't ignore it. The destructive power is too great.

"Lord, please make the eldest son ready."

Let Cao ang be ready to move to Luoyang.

It's a big deal.

It's not something they can do if they want to.

"What do you think, gentlemen?" Cao Cao is still hard to make up his mind.

The situation is very obvious. If Zhang Yu is not trapped this time, then the situation is very unfavorable to them.

Xu you said, "prepare for a big retreat, not only the army and officials, but also the people."

After a long pause, Xu you said, "the other is whether you can kill Zhang Yu. If you kill Zhang Yu, you can fight for a long time."

Zhang Yu is the emperor of the Tang Dynasty. Killing him will bring many benefits.

However, it is unrealistic to say that killing Zhang Yu will lead to the demise of the Tang Dynasty.

Tang Dynasty has a complete system, loyal army, capable minister, even without Zhang Yu, Zhang Yu's son.

Cao Cao closed his eyes, thought in silence, and said, "OK, order ang'er to preside over the retreat. You two assistants, give each of you 30000 people, and organize the retreat immediately. I want to stay and fight with Zhang Yu. "

Cao Cao has made great determination. He wants to hold Zhang Yu here to fight for time. If he can, he'd better take Zhang Yu's life.

Cao Cao is a decisive person, giving up a large area of territory, with Zhang Yu Wang to Wang's decisive battle.
