Sima Yi saw through the empty city plan, why did he take the initiative to let Zhuge Liang go? Expert: Don't try it
In the Three Kingdoms period, Zhuge Liang was known as a god man, and his brilliant plan was one after another, even if he later returned to the mountains and forests, but because of Liu Bei's way of knowing people, Sangu Maolu finally invited him out of the mountain, and became Liu Bei's right hand and left arm, and also an important basis for Liu Bei to become the founding emperor, and even some people said that if Liu Bei did not have Zhuge Liang around, it was difficult to achieve great things, of course, from some historical events, it is not difficult to see that Zhuge Liang did have quite high talent, and even from history, almost not many people can compare with him.

And the most famous is the duel between him and Sima Yi, Sima Yi is not an incompetent person, he and Zhuge Liang are also inseparable, and the most famous is the empty city plan of the two of them, in fact, in this plan, Sima Yi has long recognized this plan, and also knows that this city has long become an empty city, but he took the initiative to let Zhuge Liang go, which also makes people feel very puzzled, why did Sima Yi do this?
At that time, Liu Bei's situation was actually not good, due to the long-term war and the lack of soldiers and horses, once led the army out of Qishan, but also because of the use of the wrong people, and lost the street pavilion, but at that time Sima Yi led 150,000 troops, zhuge Liang only had more than 2,000 soldiers at that time, which was simply a huge disparity in strength, in such a critical moment, he had to come up with a plan, that is, the well-known empty city plan. After Sima Yi saw this situation at that time, we can see in some works that Sima Yi was a little frightened and felt that there might be an ambush, so he retreated one after another.
In fact, this is only an effect presented in literary works, you know, even if there is an ambush, Sima Yi, who has an army of 150,000, will not be afraid at all, and the main reason for his withdrawal is because he has already seen through the empty city plan, he is also a very smart person. Because Sima Yi at that time knew that once he broke through Zhuge Liang and took Zhuge Liang down in one fell swoop, Cao Wei at that time would definitely kill Sima Yi directly because he was jealous of Sima Yi, and he would have no use value, and his own consequences were also imaginable.
However, if Zhuge Liang can save his life in one day, he does not have to worry about the future, and he has always had use value, so in order to save himself, he can only keep Zhuge Liang, so he will directly withdraw his troops and go back to the plan. Therefore, experts said: do not withdraw to try it!
