Xu Yi

Xu Yi (onyomi: Kyo Gi) is the son of Xu Zhu and an officer of Wei. Historically, Xu Yi was born in Qiao county of Yu Province and succeeded his father's title and fief after the latter's death. During the conquest of Shu, Xu Yi served under Zhong Hui and was assigned as "General of the Van". Zhong Hui tasked him with repairing the roads to Hanzhong in order to create a safe path into Shu. However, when Zhong Hui crossed one of the bridges, the hoof of his horse was caught in the bridge and Zhong Hui almost fell from it. Zhong Hui was enraged and ordered Xu Yi's execution. Although many generals pleaded for his life due to him being the son of Xu Chu, Zhong Hui did not change his mind and executed him. During the reign of Sima Yan, his son Xu Zong inherited his title.

Role in Games
Xu Yi is a minor character in Dynasty Warriors. He appears mainly as a sub-officer in Dynasty Warriors 6, serving either directly under his father or Cao Cao. He only appears in Wei's later battles such as Shi Ting or Wu Zhang Plains. He will also defend Xu Chang against Sima Yi's rebellion. In Dynasty Warriors 8, Xu Yi only appears during Zhuge Liang's northern campaigns at Jieting and Chencang.

Romance of the Three Kingdoms has Xu Yi appear as a mediocore officer with a decent war stat, but his other stats are fairly low. He often lacks a skill and should not be used to lead units on his own, unless there is no better option. He appears quite early under Cao Cao's forces and continues to serve him and his successors.

Romance of the Three Kingdoms
Romance of the Three Kingdoms gives Xu Yi a slightly expanded role, although he still only appears in one chapter. He was appointed as leader of the van and tasked to advance through Xie and Luo valleys to repair roads, bridges and tunnels with a 100,000 men strong army. When Zhong Hui started his advance, Xu Yi led his men to Nanzheng and attacked the pass. The defender Lu Xun (盧遜) was already informed by Xu Yi's advance and positioned archers that successfully defeated Xu Yi and forced him to flee. Later, he was executed by Zhong Hui for his failure to repair a bridge.
