Sima Yi launched a coup d'état in Gaopingling, killed the general Cao Shuang, and controlled the power of Cao Wei, and after Sima Yi's death, his eldest son Sima Shi continued to control the government and act arbitrarily, causing dissatisfaction among many people.
Zhongshu Ordered Li Feng, although Sima Shi had been hand-picked up and held an important position, he was also dissatisfied with Sima Shi's monopoly, and he was relatively close to Xiahou Xuan of Taichang.
Xiahou Xuan was the son of the general Xiahou Shang (夏侯尚) and a cousin of Cao Shuang, and at the same time, Xiahou Xuan was also Sima Shi's brother-in-law, because Sima Shi's original wife Xiahou Hui was Xiahou Xuan's younger sister, and Xiahou Hui was later poisoned by Sima Shi.
Li Feng was dissatisfied with Sima Shi, so he joined forces with Zhang Ji, the father of the empress at the time, to prepare to get rid of Sima Shi, and then, Xiahou Xuan was made a general and Zhang Ji was made a general of the Hussars.
The Chronicle of the Three Kingdoms and the Biography of Xiahou Xuan records that although Li Feng was favored by the general Sima Jingwang, he had a selfish heart in Xuan, so he married empress dowager Guanglu's father, Zhang Ji, and plotted to assist the government with Xuan.
However, unfortunately, before they could do anything, they leaked the news, and Sima Shi learned of the situation and attacked first.
Sima Shi first pretended not to know, pretending to ask Li Feng to come to discuss, Li Feng did not perceive the danger, so he had no defenses, so he went, and when he saw Sima Shi, Li Feng felt that things were not good, but if he wanted to escape, he would have no chance.
Sima Shi confronted Li Feng, why did he conspire to kill him? When Li Feng saw that the matter had come to this point, he said with a straight face, "Your father and son are wolf-and-son ambitions, arbitrary power, and chaos in the government, causing danger to the society, but unfortunately I can't reach you and kill you!"
When Sima Shi heard this, he was furious, so he immediately asked the samurai to hold Li Feng to death, and put the iron ring on the handle of the sword against Li Feng's waist and beat him alive.
The Chronicle of the Three Kingdoms quotes the "Spring and Autumn of the Wei Dynasty": The great general blames Feng, Feng Zhi is troubled, and Sui Zheng se knows: "Qing Father and son are adulterous, they will fall into the community, and they will be inferior to each other, and they cannot destroy each other's ears!" "The great general was furious, and the warrior built a plump waist with a sword ring and killed him.
Sima Shi then immediately sent people to arrest Zhang Ji and Xiahou Xuan, along with Ling Ledun of the Yongning Bureau, Liu Xian, and others, to exterminate all three tribes, including the empress, and send the rest of their relatives and children to Lelang County.
The Chronicle of the Three Kingdoms and the Biography of Xiahou Xuan records that Princess Qi Chang, the former emperor's beloved, was the original death of her third son. Therefore, the Feng, Xuan, Ji, Dun, and Xian all yi tribes, and the rest of the relatives migrated to Lelang County.
Li Feng's son, Li Tao, married Princess Qi Chang, the eldest daughter of Emperor Cao Rui of Wei and the only child of Cao Rui to live to adulthood.
At that time, Princess Qi gave birth to three sons, and because of her status as a princess, she and her three sons were spared death, and Li Tao, a donkey, was given death in prison.
Later, Princess Qi Chang remarried to Ren Kai.
Xiahou Xuan was Sima Shi's brother-in-law, but Sima Shi did not spare Xiahou Xuan, which shows Sima Shi's cruelty.
In order to monopolize power, The Sima clan usurped Jiangshan, massacred on a large scale, and under the butcher's knife, countless people's lives were slaughtered, and soon, it caused Wuhu chaos and caused great disasters, until Liu Yu put an end to Sima Shi's Jiangshan.
