The so-called heroes of the chaotic world were in the war-torn era of the Three Kingdoms. Cao Cao's heroic figure also came into being. Throughout his life, he had outstanding military talents, but also had a high degree of achievement in literature and calligraphy, as well as in the good use of knowledge. So why did a number one person like him fail to unify the three kingdoms in the end? Mainly because he let these two people go.
The first is Liu Bei. Before and after cooking wine on heroes, he had several opportunities to kill Liu Bei. Moreover, he also saw that Liu Bei would become a great thing in the future. When cooking wine and talking about heroes, he also said to Liu Bei: The heroes of the world are for me and jun'er. In his eyes, Dong Zhuo, Yuan Shao and Liu Biao were all dismissive. Liu Bei was immediately panicked when he heard this, when suddenly a thunderclap of thunder on a sunny day frightened Liu Bei's chopsticks away. Moreover, his adviser Guo Jia had always advised him to kill Liu Bei in order to avoid any trouble.
However, Cao Cao did not take the advice of his advisers. In the end, the tiger returned to the mountain, so that Later Liu Bei became his strongest opponent. At the Battle of Hanzhong, Cao Cao was defeated. After this battle, Cao Cao never led his troops to the battlefield again, and also announced the end of Cao Cao's military career. He later died of illness and was succeeded by his son Cao Pi.
The second was Sima Yi. His failure to kill Sima Yi was more serious than his failure to kill Liu Bei, which later led to the seizure of all the power of his Cao clique by Sima Yi. From this, it can be seen that his failure to kill Sima Yi was the most fatal mistake.
From the beginning, he also found that Sima Yi was a figure with eagle eyes and a wolf's heart, good at hiding, lurking, and waiting for opportunities. So that when Cao Cao was alive, he always restricted Sima Yi's development, so that Sima Yi was not reused. He had also tried many times to attack Sima Yi and kill him quickly. The latter did not succeed in killing, mainly in two aspects.
On the one hand, Sima Yi is a person who is good at lurking in hiding. He did his best under Cao Cao and endured hardships and grievances. No matter how Cao Cao tried to test him, how he tried to hurt him, he did it wholeheartedly, and on the surface he showed no complaints. Over time, Cao Cao's killing intent towards him slowly weakened.
On the other hand, Sima Yi tried his best to please Cao Pi and offer advice to Cao Pi, which won Cao Pi's liking. Because Cao Pi is cao Cao's successor after all, holding this big tree is equivalent to saying that there is a protective umbrella to save his life. So much so that when Cao Cao wanted to attack him many times, Cao Pi came forward to say good things. Cao Cao listened to him for a long time and slowly gave up the idea of killing him.
Even so, Cao Cao was still very worried about Sima Yi when he was dying, so he warned Cao Pi to beware of Sima Yi. Moreover, he also left 4 loyal old ministers to guard against Sima Yi. But what he never expected was that Sima Yi lived so long that he survived three generations of his Cao family, which eventually led to the situation of the three families returning to Jin.
On the whole, Cao Cao was already cruel enough to Sima Yi. It can only be said that Sima Yi was too good at disguise and tried all kinds of ways to deceive Cao Cao. If Cao Cao was a little more ruthless, he would get rid of Sima Yi directly. Then there was nothing that happened to Sima Yi. After all, Cao Cao was also a mortal fetus in the flesh, so it was understandable that he made such a mistake. If you have any different views on this, please leave a comment below.
