Speaking of Cao Cao's most famous strategists, the first thing that comes to mind is probably The strategist Guo Jia. Guo Jia's knowledge and cunning make people have to sigh. However, xun Yu, the sage who helped Cao Cao more and accompanied Cao Cao for a longer time, was often overlooked. Xun Yu's contribution to Cao Cao surpassed Guo Jia's, and his strength was comparable to Guo Jia's. One of the great historical plans of holding the princes hostage to the Heavenly Son was also provided to Cao Cao by Xun Yu.
However, from the events in history, we can see the weight of Guo Jia in Cao Cao's heart. But the defeat of the Battle of Chibi was really lost because there was no Guo Jia?
In fact, throughout history, cao cao was too suspicious and ignored Xun Yu's persuasion, which eventually led to the defeat of the Battle of Chibi.
Before the expedition, Xun Yu formulated a very strict and meticulous strategic plan for Cao Cao. He not only clearly calculated the strength of the enemy, but also analyzed the leadership style of each general according to the character of the enemy leader. From a historical point of view, Xun Yu's plan is the most meticulous and most likely to succeed.
Unfortunately, Cao Cao did not take Xun Yu with him, nor did he adopt his plan before the battle, which made Xun Yu's preparations in vain, which also indirectly led to the defeat of the Battle of Chibi. In the end, Cao Cao only cared about Guo Jia, but forgot to help him so much Xun Yu.
As we all know, Cao Cao was ambitious, and he had the determination to become king. It was this that was very different from Xun Yu, who was loyal to the Han Dynasty. For Xun Yu, restoring the Han Dynasty was his ultimate goal, helping Cao Cao because he thought that Cao Cao was a courtier and would not have too much ambition, but he did not expect him to make a mistake.
Later, Cao Cao and Xun Yu parted ways. However, as mentioned above, Xun Yu's contribution to Cao Cao was far greater than Guo Jia's. With such an important talent gone, Cao Cao must have been suspicious.
Only the dead can't speak. Cao Cao sent xun yu a box of poisonous food and ordered the people to watch xun yu eat it. Xun Yu had already figured out Cao Cao's character and knew that he was doomed to die, and could only eat with tears and die with hatred.
It is the so-called cycle of cause and effect, and who the heavens have spared. After Xun Yu's death, his son Xun Yu spent many years lying down for revenge. He did not hesitate to make a horse for the Sima clan, and with his outstanding talent, he soon gained the heavy use of the Sima family. Subsequently, Cao Shuang ascended to the throne and persecuted some excellent ministers, and Xun Yan has been secretly protecting these ministers, drawing relations and gaining a large number of sages.
Secondly, Xun Yan secretly contacted Sima Yi of the Sima clan and launched a mutiny to destroy Cao Shuang's party. Since then, Xun Yan has become the top military division of the Sima family, after all, the enemy of the enemy is a friend. Then, Xun Yan lured the Sima family to wipe out the Cao clan, and finally, Cao Cao's descendants were slaughtered by Xun Yan and the Sima family, and there was no day of comeback.
