Why didn t Sima Yi kill Cao Shuang, who was a great threat to him, when he was in power?

Sima Yi acted in a scene in order to depose Cao Shuang's military power, not to hurt Cao Shuang's life, and to deceive Cao Shuang into being defenseless. In the end, he was killed by Sima Yi, and his reputation was ruined and he was punished by the Nine Clans.

Because Sima Yi's rights were not consolidated at that time, in order for the people of the world not to suddenly make trouble, he couldn't kill Cao Shuang of the Wei family.

When Sima Yi was in power, it was actually because Cao Shuang still had value for him, although he was a great threat to himself, he still didn't kill him.

A big threat doesn't mean you can't control it, this kind of mentality is like raising a pet snake, knowing that it is dangerous but controllable, Sima Yi is enjoying the fruits of his victory by doing so.

Cao Shuang is the general of the Wei State, holding military and political power, according to common sense, Sima Yi's rebellion is unlikely to succeed, but Sima Yi took advantage of Cao Shuang and others to worship their ancestors, launched a coup d'état, so that the Sima family held great power.

Cao Shuang lost to Sima Yi, in addition to his average IQ and mediocrity, but also because Sima Yi was yin, ruthless, and able to pretend. The horse is in love with the trough, and he is reluctant to have a beautiful wife. Zhengye was naïve and naïve, after Sima Yi saw his paper tiger clearly, he seized the powerful fighter and took Cao Shuang in one fell swoop in the name of the Empress Dowager Guo.

Cao Shuang thought that Sima Yi would let himself go like Cao Shuang would let Sima Yi go. As everyone knows, Sima Yi needs to clear the obstacles to usurpation, he needs to make an example of one hundred people, and he needs to master the military power.

Gao Pingling mutinied, Sima Yi was a failure, and he was burned. One of them, Heng Fan, a think tank, fled and took the general's seal with him. Second, Cao Shuang can coerce the world to order the world, but he doesn't know how to use it.

San Cao Shuang was intimidated by Sima Yishen's might, and Heng Fan said that the puppet still knows how to save his life. Cao Zhen's sons are not as good as pigs and dogs. Throw yourself into the net.

Sima Yi has been deeply cultivated for decades, and his protégés and former officials are all over the government and the opposition, and he is also actively trying to win over Cao Shuang's opposites. Although he pretended to be sick at home, he did not resign as Taifu, and this position still has a strong influence. And his identity as a representative of Confucianism and the family with his own traffic still maintains a high degree of fan stickiness.

Cao Shuang controls the little emperor - and he is not on the same page as he is, as I explained in the previous Q&A, and he enveloped the Empress Dowager Guo by marriage. Cao Shuang does not have an absolute advantage over Sima Yi, he just feels good about himself. It was precisely because Sima Yi did not lose his power that he pretended to be sick to confuse Cao Shuang, and after he relaxed his vigilance, he dealt a fatal blow.

And it is easier for the dignified Taifu to gain sympathy and support if he is so down, thus pushing Cao Shuang to the opposite side of injustice. One is in the light and the other is in the dark, and the situation has already been quietly reversed. Cao Shuang cares about power, but Sima Yi cares even more, a 71-year-old man would rather pretend to be crazy and stupid than resign to support his retirement, for what is self-evident.

During the Gaopingling Rebellion, Sima Yi first gave the Empress Dowager Guo legitimacy and the Empress Dowager's order, and at the same time closed the city gate to occupy the arsenal, and took command of Cao Shuang and Cao Xi's barracks. Sima Yi's family has a clear division of labor: the younger brother Sima Fu and the eldest son Sima Shi guard the Sima Gate, the second son Sima Zhao keeps an eye on the two palaces, and Sima Yi himself garrisons the Luoshui pontoon bridge to control the key points.

Everything was deployed neatly and orderly, and it is estimated that my brain was not idle for a moment when I was pretending to be sick at home, and I was thinking about it. Although Cao Shuang is a general and has military power, he can't quench his thirst from far away, and he has no place to stand in Luoyang. The key is that Sima Yi also controls the Cao brothers' families, and this most easily ignored reason is precisely Cao Shuang's biggest weakness.

Because Sima Yi had already rebelled, he took Luoyang under control when Cao Shuang and they went out to play, and then launched a military coup, and Cao Shuang also surrendered to Sima Yi, so he was defeated by Sima Yi in the end.

Sima Yi took advantage of their trip to Luoyang to take Luoyang City into his own hands, and then launched a military coup, and later Cao Shuang chose to surrender.

Mainly because of Cao Shuang's lack of appeal, many people are very disappointed in Cao Shuang, and the family is very supportive of Sima Yi.
