Although Deng Ai had accomplished extraordinary feats, in Sima Zhao's eyes, his actions in the Shu Han after Liu Chan surrendered were somewhat suspicious of wanting to establish himself as emperor.
Deng Ai and Zhong Hui attacked Shu Han together. Deng Ai sent out a surprise force, sneaked across Yinping, captured Shu Han, and directly opened the gate of Chengdu. Liu Chan and others went out of the city to surrender. At this moment, Deng Ai can say It is infinite scenery.
Before the expedition, Sima Zhao said that if it was captured, Zhong Hui would stay in Shu Han to guard it and Deng Ai would return to the court. However, it can be said that most of the conquest of Shu Han this time was due to Deng Ai, and Zhong Hui It was just holding Jiang Wei back. When Deng Ai entered Chengdu, Zhong Hui was still far away, and Deng Ai did not obey Sima Zhao's orders at this time. He believed that the orders of the foreign emperor would be ignored.
After taking control of Shu Han, he used the name of the emperor to enfeoff the people of Shu, including Liu Chan, his son, and most of the civil and military ministers of Shu Han. At the same time, he held a banquet in Shu Han to reward the three armies and everyone in Shu Han. His purpose was to Let Shu Han feel the tolerance and kindness of Wei State, and he did achieve his goal. Many Shu Han ministers stated that they would follow Deng Ai life and death.
But in the eyes of Sima Zhao, this is not the case. Deng Ai has actually committed a taboo by using the name of the emperor, and Deng Ai has not reported these things before, which means that he has completely It was Deng Ai's personal idea, so in Sima Zhao's opinion, Deng Ai most likely wanted to use Liu Chan to rule Sichuan and Shu.
Furthermore, Zhong Hui saw that Deng Ai had completely stolen the limelight this time, and felt very uncomfortable. He also wrote to Sima Zhao to fan the flames, and Sima Zhao became even more convinced, so Later, he directly ordered Deng Ai to return to the court and exterminated his clan.
