In the first month of 249 AD, the Cao Shuang brothers accompanied the Wei emperor Cao Fang to the Gaoping Tomb, dozens of miles away from Luoyang, to pay homage to the Wei Ming Emperor Cao Rui. At that time, Sima Yi saw that the time was ripe, and he released Empress Guo, who was under house arrest, and in the name of Empress Guo, ordered the closure of various gates, and sent dead soldiers to occupy the arsenal and the Luoshui pontoon bridge to cut off the possibility of Cao Shuang and others entering the city. At the same time, Sima Yi also ordered Situ Gao Rou to act as the general and occupy Cao Shuang's camp, and the Tai servant Wang Guan to act as the leading minister and occupy Cao Xi's camp. Subsequently, Sima Yi reported Cao Shuang's crimes to Cao Fang, and Sima Yi said that when he returned from Liaodong, Cao Rui had pulled his arm to support him, and this was also something that Cao Fang had seen with his own eyes, but now the great general Cao Shuang had betrayed Cao Shuang's will, corrupted and disrupted the state's system, and such a figure must be punished. When Cao Shuang received a note from Sima Yi to Cao Fang, he did not dare to inform Cao Fang, and at the same time did not know what to do, in this case, Cao Shuang could only leave Cao Fang's car to stay in the south of Yishui, cut wood to build a defensive fortification, and dispatched thousands of Tuntian soldiers as guards.
In order to increase the success rate of the incident, Sima Yi sent Shizhong, Gaoyang's Xu Yun, and Shangshu Chen Tai to persuade Cao Shuang to surrender and confess his guilt as soon as possible; he also sent Cao Shuang's trusted lieutenant Lieutenant Yin Damu to tell Cao Shuang that he was only removed from his official position, and in order to increase the credibility of the oath, Sima Yi even pointed to Luo Shui and swore an oath. Although The Great Si Nong Heng fan did not hesitate to risk his life and went out of the city to advise Cao Fang, Heng Fan believed that Cao Shuang had Cao Fang in his hands, and naturally was not afraid of Sima Yi occupying Luoyang, as long as Cao Shuang's brothers brought Cao Fang to Xuchang and then mobilized four forces to attack Luoyang, Sima Yi would undoubtedly be defeated. Unfortunately, Cao Shuang himself was weak, and he was afraid of Sima Yi's ability, so he did not accept Heng Fan's suggestion, and he naively thought that Sima Yi was only going to seize power and would not take his own life, so Cao Shuang gave the power in his hands to Sima Yi. However, Sima Yi not only seized power, but later also cursed the three tribes of Cao Shuang, and cao Wei's power fell into the hands of the Sima family.
It was precisely because Sima Yi was obviously the elder of the Four Dynasties and the chancellor of Cao Pi and Cao Rui, but he finally did such a vicious thing as seizing power, and compared with Sima Yi, Zhuge Liang in Shu Han was also entrusted with heavy responsibilities by Liu Bei, and Liu Bei entrusted Shu Han and Liu Chan with full power to Zhuge Liang, but even if Zhuge Liang held great power, he did not abolish Liu Chan and establish himself as emperor, and there was no act of half-point trespassing in this life. It is precisely because Zhuge Liangzhuyu was in front of him that Sima Yi became a great traitor and a great evil person, is this really the case?
In fact, Sima Yi was not a great traitor and a great evil person, after all, after the change of the beginning, Sima Yi had not been subject to the Nine Xi, nor had he been enfeoffed as a duke, let alone the imperial power of Cao Wei. Moreover, Sima Yi was born in the hands of Xun Yu, has always admired Xun Yu, and Xun Yu is also a teacher and friend, if Sima Yi does not have the heart of a half-king, disloyalty and injustice, it should be unlikely. And Sima Yi was a subject for forty years, after three generations of kings, after the death of his father and brother, Sima Yi carried the fate of the family, so Sima Yi naturally had to make some plans for the family.
For Sima Yi, he was also worried that the emperor would abolish his own chess piece in the future, so he wanted to seize power by resisting. What's more, during the Three Kingdoms period, countless people demanded self-preservation, and Sima Yi was just a relatively special person among them, although Sima Yi seized power because of selfishness, but he was loyal to his own family, for Sima Yi, first of all, he had to ensure the prosperity of his own family, and then he would consider the prosperity of Cao Wei, so Sima Yi was certainly not noble, and what he did was just seeking the greatest benefit for his own family. But apart from these, Sima Yi is just an ordinary person who cares for his family.
The author believes that Sima Yi violated Cao Rui's trust and is indeed criticized, but putting aside these points of view, Sima Yi is actually an ordinary person, not a person who commits great adultery and evil.
