In fact, the key is not the 3,000 dead people secretly cultivated by Sima Yi, but just his tool to seize power. What really enables him to replace Cao Wei is his wisdom. Even today, these three philosophies of existence are still worth learning and learning from each of us.
First, keep a low profile. Sima Yi, who is capable of writing and martial arts, has always been on guard against Cao Cao, and even worried that it would be bad for Cao Wei. Cao Cao tried to kill him several times. Faced with such a situation, Sima Yi knew that the only thing he could do was to endure, and he had to accept it calmly no matter what the situation was. Only in this way can the authorities in Cao Shi gradually neglect to guard against him. So Sima Yi spent most of his time in Wei. It was not until there were loopholes in Cao Shuang's body that he finally started the plan of usurping power.
Second, establish prestige. One of the biggest enemies facing Wei is Zhuge Liang, but looking around, no one in Wei is his opponent. Sima Yi became the best candidate, which was a great opportunity for him to establish his prestige in Wei. In the face of Zhuge Liang's repeated attacks, Sima Yi was able to cope calmly and successfully repel Zhuge Liang.
Because Zhuge Liang sent troops from Yizhou, the supply of grain and grass was a fatal weakness, which led to the need for a quick decision of the Shu army. Sima yi, on the other hand, was extremely clever. He saw through Zhuge Liang's tricks at a glance and deliberately failed to persist in bringing Zhuge Liang down. In the end, Zhuge Liang was defeated by Sima Yi. These achievements of Sima Yi made him gain high prestige in the Cao Wei army, and the soldiers respected him very much.
Third, seize the opportunity. Although Sima Yi's power was promoted by Cao Shuang, Sima Yi knew all this and didn't care. He was confident that Cao Shuang's ingenuity was not as good as his, so he just pretended to be ill and completely deceived Cao Shuang. When Mr. Cao took a hundred officials with him to pay a visit to Gao Ping Ling in high spirits, Sima Yi smelled that this was an excellent opportunity, so he personally took people into the palace, held the Queen Mother hostage, and then took control of the whole capital.
And Cao Shuang, who looks arrogant, is just a paper tiger. Seeing that Sima Yi took control of Luoyang, he surrendered the military power without resistance. Cao Shuang thought he would win Sima Yi's kindness by showing weakness, but he was naive. After Sima Yi took control of Cao Wei's power, Cao Shuang and his henchmen were first cleaned up. In the end, Cao Wei, managed by several generations in Cao Shi, completely fell into the hands of Sima.
Therefore, Sima Yi's title of "Tomb Tiger" is not a hollow name. Compared with Zhuge Liang, who is known as "Wolong", it can be seen from the above aspects that Sima Yi is obviously more intelligent!
