Deng Zhong and troops and it turned out to be a great success. They eventually managed to enter Chengdu, and the Shu emperor Liu Shan
surrendered. Zhong Hui and Deng Ai became fierce rivals due to the race to Chengdu, which Deng Ai won.

Jiang Wei, however, did not want Shu to fall. He determined that Zhong Hui wanted to rebel against Wei. They united, defamed Deng Ai, and ordered Wei Guan to capture him. Jiang Wei's plan failed and the Wei army killed Zhong Hui and Jiang Wei. These soldiers tried to rescue Deng Ai, but Wei Guan feared that they might take vengeance on him so he killed both Deng Ai and Deng Zhong.
