Wei Guan
Later that year, after the Shu emperor Liu Shan had surrendered and Shu had been vanquished by Wei, Zhong Hui planned to rebel against the Cao Wei state. He accused Deng Ai of plotting a rebellion and had Deng Ai arrested and sent back to the Wei capital, Luoyang. Zhong Hui staged a revolt in 264 but it was crushed and he lost his life. Deng Ai's subordinates wanted to bring their superior back from Luoyang. Wei Guan, another Wei officer who plotted with Zhong Hui against Deng Ai, feared that Deng Ai would take revenge on him if he returned, so he instigated Tian Xu to kill Deng Ai by reminding him of how Deng Ai wanted to execute him at Yinping in the previous year. Tian Xu led his men to intercept Deng Ai at Sanzao Village (三造亭), Mianzhu, where he killed Deng Ai and his son Deng Zhong (鄧忠).
