Cao Cao especially likes recruiting talents. Knowing that Sima Yi was capable, he used his family to make him work for himself. Sima Yi was really capable, so when he was assigned to Cao Pi, he also gave him a lot of good advice. Finally, Cao Pi became the final winner with the help of Sima Yi.
Xelloss succeeded, and Sima Yi, a meritorious minister, naturally succeeded in coming to the front desk. He became a great official by virtue of his intelligence, but after Cao Pi's death, Cao Rui's superior Sima Yi finally got his hands on the army. Sima yi, who got his hands on the army, can be said to be invincible. Finally, he even developed this army into his own private army.
Sima yi finally succeeded, but he never rebelled, because he thought rebellion was an unreasonable thing, and Sima yi, who believed in Confucianism, naturally wouldn't do such a thing. But he knew that Si Mazhao wanted to be king, so he gave Si Mazhao a piece of advice before he died.
Sima Yi was in a trance when he died. In a trance, he saw that all his colleagues who had died before had come to see him. When people are dying, their words are very good. He didn't want Si Mazhao to suffer these tortures in the future, and he finally repented, so he finally said four words, that is, be cautious, be cautious.
Maybe others don't know what this means, but Si Mazhao knows it very well. It is precisely because he clearly understood Sima Yi's good intentions that he did not choose to be emperor until his death, so he ended his life in such a chic way. In the end, his wish was realized by his son.
