|Real name:||Xu Yi|
Xu Yi was the son of General Xu Zhu of Wei, and took part in the defense of Hanzhong in 219 AD, but was defeated alongside Guo Huai and Cao Zhen in a failed attack on the Shu main camp. Xu Yi volunteered to be Leader of the Van, who would make roads and repair bridges, in the invasion of Shu in 263 AD. Men agreed with him, saying that nobody was fitter to do the job. He was to command 5,000 cavalry and 1,000 infantry and split into three divisions to conquer Hanzhong. He marched out immediately to work, 100,000 troops behind him. But he was anxious for a startling exploit, and diverted to Nanzheng. Zhong Hui scorned him for not doing his duty; his horse almost tripped on the bridges had it not been for Xun Kai, and the delinquent was put to death because of his failure.
