Sima Zhao
In 262, Sima Zhao noted that Shu was growing weak and lacking in resources after constantly waging war against Wei, so he wanted to launch a large-scale invasion of Shu to eliminate the threat of Shu. Among those he consulted, only Zhong Hui agreed that Wei was capable of conquering Shu. Zhong Hui then assisted Sima Zhao in formulating a strategy for the conquest of Shu.
