Starting in 194, Sun Ce borrowed troops from Yuan Shu and embarked on a series of conquests in the Jiangdong (or Wu) region. He attacked territories under the control of warlords such as Liu Yao, Yan Baihu and Wang Lang and conquered them. When Sun Ce was trapped in Niuzhu (), Wu Jing came to his nephew's rescue and captured all the enemies. Wu Jing participated in Sun Ce's campaign against Liu Yao in 195. When Liu Yao fled to Yuzhang Commandery (豫章郡; around present-day Nanchang, Jiangxi) after his defeat, Sun Ce sent Wu Jing and Sun Ben to Shouchun (壽春; present-day Shou County, Anhui) to report his victory to Yuan Shu. Concurrently, Yuan Shu was fighting with another warlord Liu Bei for control over Xu Province, so he appointed Wu Jing as the Administrator of Guangling Commandery (廣陵郡; in present-day Jiangsu).
