In the Novel

Wu Yi first appears in Chapter 62 of Romance of the Three Kingdoms, where, as Liu Zhang's maternal uncle, he plays an important role in Liu Zhang's faction. After Liu Zhang's subordinate general Deng Xian was defeated in a clash with Liu Bei's army, Liu Zhang's eldest son Liu Xun volunteered to go and garrison Luocheng. At this point Wu Yi volunteered himself, declaring his willingness to assist Liu Xun in going to Luocheng; Liu Zhang approved, saying, "It is best of all to have my honored uncle go"^[1]. This shows that Wu Yi held not only a distinguished position in Liu Zhang's faction but also considerable trust.

In the defense of Luocheng, Wu Yi joined Liu Gui, Zhang Ren, and others in resisting the attack of Liu Bei's army. When they learned that Leng Bao had been defeated and captured, Wu Yi deliberated countermeasures with Liu Gui and Zhang Ren. Zhang Ren proposed that he himself lead troops to guard the small road to the southeast of the city, while Wu Yi and the others would be responsible for holding Luocheng firmly^[2]. In the fighting that followed, Zhang Ren's scheme failed and instead cost two senior generals, leaving the city in a perilous situation. Wu Yi and Liu Gui advised Zhang Ren to send men to Chengdu for reinforcements on the one hand, and on the other to seek a decisive battle with the enemy. Zhang Ren proposed a scheme of feigned defeat to lure the enemy, while Wu Yi declared he would assist Liu Xun in holding the city and lead troops out to support the fight^[3].

In one engagement, however, Wu Yi was unfortunately captured by Zhao Yun. When he was brought before Liu Bei, Liu Bei asked whether he was willing to surrender. Wu Yi replied: "Since I have been captured, why should I not surrender?"^[4] showing his pragmatic attitude. Liu Bei was greatly pleased and personally loosened his bonds. Zhuge Liang then asked Wu Yi about the defending generals in Luocheng, and Wu Yi gave a detailed account of Liu Xun, Liu Gui, and Zhang Ren, noting in particular that Zhang Ren "is a native of Shu Commandery, of great courage and strategy, not to be underestimated"^[4], providing important intelligence for Liu Bei's faction's subsequent military dispositions.

After Liu Bei pacified Yi Province, Wu Yi came over to Liu Bei's faction and continued to serve Shu Han. In Chapter 92, during Zhuge Liang's Northern Expeditions, after successfully seeing through Cui Liang's feigned-surrender scheme, Zhuge Liang imprisoned Xiahou Mao. To consolidate his gains and continue advancing his military operations, Zhuge Liang arranged for Wu Yi to garrison Nan'an and Liu Yan to garrison Anding, so as to free Wei Yan's troops to attack Tianshui Commandery^[5]. This shows that Wu Yi was still entrusted with important duties in the later Shu Han period, responsible for important defensive tasks.

In Chapter 105, after Zhuge Liang's death, the Shu Han regime carried out major personnel adjustments. In accordance with Zhuge Liang's last words, the Later Lord Liu Shan promoted Jiang Wan to Chancellor and Grand General, and Fei Yi to Prefect of the Masters of Writing, while Wu Yi was promoted to General of Chariots and Cavalry and given the staff of authority to command Hanzhong. He went out to garrison Hanzhong together with Jiang Wei, to guard against an incursion by Wei troops^[6]. This shows that Wu Yi remained an important military general in the later Shu Han period, bearing the heavy duty of guarding the frontier.
