Xu Yi

Xu Yi (onyomi: Kyo Gi) is Xu Zhu's son.

Historically, he was born in Qiao county, 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 to pave a trustworthy path into Shu. When Zhong Hui was crossing one of the constructed bridges, he almost fell when his horse's hoof was caught in its boarding. Enraged, he ordered for Xu Yi's execution. Although many generals pleaded to spare him to honor Xu Chu, Zhong Hui's word was final. Xu Zong, Xu Yi's son, inherited his title during Sima Yan's reign.

Role in Games
Xu Yi is a minor character in the Dynasty Warriors series who mainly appears in Wei's later battles. He's a sub-officer in Dynasty Warriors 6, serving either directly under his father or Cao Cao. He defends 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.

In Wei's side of Chengdu during Dynasty Warriors 9, Xu Yi will be in charge of making a bridge to Chengdu and will request the player to gather materials and someone who knows how to build bridges. Ironically, Zhong Hui is the first one to successfully cross the bridge once it is built. In Shu's side, he will be a part of Zhong Hui's unit and will attempt to cross the bridge if the defenders do not destroy it in time.

The later Romance of the Three Kingdoms titles has Xu Yi appear as a mediocre officer with a decent war stat and fairly low other stats. He often lacks a skill and should not be used to lead units on his own. 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.
