司馬昭
In 260, Sima Zhao again forced Cao Mao to issue an edict granting Sima Zhao the Nine Bestowments and the promotions, which Sima Zhao declined again, but which drew Cao Mao's ire. He gathered his associates Wang Shen, Wang Jing, and Wang Ye and told them that, while he knew the chances of success were slight, he was going to act against Sima Zhao. He took lead of the imperial guards, armed himself with a sword, and set out toward Sima Zhao's mansion. Sima Zhao's brother Sima Zhou tried to resist, but after Cao Mao's attendants yelled loudly, Sima Zhou's forces deserted. Jia Chong then arrived and intercepted the imperial guards. Cao Mao fought personally, and Jia Chong's troops, not daring to attack the emperor, were also deserting. One of the officers under Jia Chong's command, Cheng Ji (成濟), after asking Jia what to do and was told by Jia to defend the Sima power regardless of the consequences, took a spear and killed Cao Mao with it. This left Sima Zhao thoroughly vexed.
