Before Cao Cao left Xuchang, he made a plan, that is, to make Zhang Yi find some trouble. So he gave Zhang Yi an official position as a general of Zhengdong on the one hand, and found a trouble for Zhang Yi.

This trouble is Liu Bei!

Guo Jia's original strategy said: "Zhang Yi is absolutely extraordinary, the lord and he have tried many times openly and secretly, but they have not gained the upper hand, which shows that Zhang Yi is indeed the best among people." However, Zhang Yi has shortcomings in the defense line set up in the north. ”

"Zhang Yi left Liu Bei in Runan with two intentions: one is to let Liu Bei fight against our army, and the other is to trap Liu Bei in Runan."

Cao Cao asked, "Trap Liu Bei in Runan?" Why is that? ”

Guo Jia said: "The thirteen states of the Han Dynasty, the north is now in the owner's pocket, and Yangzhou Zhang Yi is solid, so there are not many places for Liu Bei to choose, it is nothing more than Jingyi two states." ”

"Jingzhou Liu Biao was quite enterprising a few years ago, but now it is twilight. Liu Zhang of Yizhou is just a dog guarding the land, and sooner or later he will be taken away. ”

And Zhang Yi wants to defeat the lord, but he can't rely on Yangzhou alone. Therefore, he will first take Jingyi Erzhou and compete with the lord north and south. ”

Cao Cao immediately said vigilantly: "Zhang Yi trapped Liu Bei in Runan because he wanted him to attack Jingyi by himself, so that he would not have a strong opponent?" ”

Guo Jia nodded and said: "That's right, and Liu Bei is obviously aware of this, so he has stopped going against the lord in the past two years, but is accumulating strength." ”

Cao Cao said: "I'll send someone to negotiate with Liu Bei!" ”

Cao Cao sent a person who was good at negotiating, full of favor! When it came to Gushi to negotiate with Liu Bei, the intentions of the two sides could be said to be a hit off. However, there are some differences between the two sides in the details, and Liu Bei directly wants to leave Runan.

But how could Cao Cao agree, he wouldn't let Liu Bei go for no reason. If Liu Bei had no effect, he would definitely trap Liu Bei, and finally trapped Liu Bei, a tiger, how could he let it go easily?

So the condition on Cao Cao's side is that Liu Bei will attack Zhang Yi and hold out for a month, and then Cao Cao will let Liu Bei go to Jingzhou with his army.

Liu Bei very much wanted to take away his army, his army was not ordinary. It's all about what he's trained over the years. Among them, there are Bai Yu soldiers who have been trained from Xuzhou, and cavalry brought from Yecheng, these cavalry are not as simple as cavalry alone, many of them are from the white horse Yicong.

Liu Bei was reluctant to let these soldiers go, so he didn't leave Runan. If Liu Bei had few soldiers and horses, he would be able to be ruthless and take refuge in Liu Biao as in history.

But he had seven or eight thousand soldiers, and these were enough soldiers for him to quickly occupy a place and start anew.

So no matter what, Liu Bei will try his best to keep his soldiers and horses, he is not young, and he does not have the courage to start again.

So Liu Bei agreed to Cao Cao's proposal and launched an attack on Lujiang on the date set by Cao Cao.

When Zhang Yi was about to send troops to support Cao Cao's hind legs, he received the news that Liu Bei was attacking Yangquan.

Zhang Yi originally put three generals in Yangquan, Anfeng and Tatexian County, that is, Xue Rengui, Hua Rong and Yang Zhi.

Their role here is to guard against Cao Cao's attack or Liu Bei's rebellion, and as soon as Liu Bei defects, they are ready.

Although Liu Bei's attack was unexpected by many people, Zhang Yi had already confessed that he must be careful of Liu Bei. Naturally, the three of them did not dare to be careless, because this was their main task here.

Xue Rengui, Hua Rong, and Yang Zhi took turns to change defenses, just in time for Hua Rong to defend Tatexian County. When Liu Bei came, he was discovered by Hua Rong, and then Pegasus sent people to inform Yang Zhi in Yangquan and Xue Rengui and Shouchun in Anfeng.

After Zhang Yi received Hua Rong's military report, he was very angry. Okay, you Liu Bei, you really betrayed, no wonder you have been asking for benefits for the past two years, and you don't want to do it at all, you have long been preparing to give yourself this from behind!

But Liu Bei should know his military strength! Why are you still stupidly attacking? It must be Cao Cao who gave him some benefits, so that he could attack himself even at the risk of losing his old capital.

So what benefits did Cao Cao give Liu Bei? This was something that Zhang Yi couldn't guess, so he convened everyone to discuss.

Liu Ye said: "The lord's intentions are actually not difficult to guess, Liu Bei noticed it two years ago. Cao Cao has a large number of capable men, so he can naturally guess it. I think Liu Bei must have wanted to jump out of Runan, and Cao Cao also took advantage of this to blackmail Liu Bei. ”

Zhang Yi said: "In this case, Liu Bei shouldn't do his best to attack Lujiang, right?" ”

Liu Muzhi said: "The lord must not think so. If I guessed correctly, Cao Cao must have let Liu Bei go to Jingzhou. If the lord is not in Runan and destroys Liu Bei, the resistance will become even greater when the time comes to attack Jingzhou. ”

When Zhang Yi heard this, he immediately figured it out. He has been trapping Liu Bei in Runan because he is afraid that he will go to Jingzhou, and once Liu Bei goes to Jingzhou, the situation will not be good.

According to the historical trajectory, Liu Bei will be supported by many people when he goes to Jingzhou, and Jingzhou people such as Zhuge Liang, Yizhi, and Ma Liang will follow him. Moreover, Liu Bei also received a lot of powerful generals in Jingzhou, Huang Zhong, Wei Yan, and Huo Jun are all very capable people.

Although the trend of history has changed now, Zhang Yi is still not sure whether these talents will take refuge in Liu Bei. It can be said that once Liu Bei is released to Jingzhou, Zhang Yi will not be able to ensure the integrity of Jingzhou's talent pool.

Talent in the 21st century is the most important, and talent in the 3rd century is also the most important. Zhang Yi has coveted Jingzhou's talent pool for a long time, and he will not give up. Although those talents are all children of the family, and Zhang Yi doesn't pay much attention to them in front of others, he knows in his heart how much he longs for these talents, you must know that many talents there are talents from the state and county, and when he governs the world in the future, he will definitely need these people, if he lets them go, then he needs to go to Yizhou to get a batch.

However, Yizhou people are particularly xenophobic, and Zhang Yi doesn't know if he can get the support of Yizhou people. If it doesn't work, Zhang Yi can only open the killing ring.

But the most important thing now is to solve Liu Bei, if Liu Bei is not solved, Zhang Yi can only start attacking Jingzhou as soon as possible.

Xue Rengui alone will definitely be able to block Liu Bei's attack, but it is impossible to completely defeat Liu Bei and let him lose most of his soldiers and horses.

So Zhang Yi immediately mobilized 20,000 soldiers and horses, and then personally led the troops to Anfeng, preparing to design to get rid of Liu Bei.
