Xu Shu was singing on the streets of Xinye when Liu Bei noticed him and asked him if he was either the "Sleeping Dragon" or the "Fledgeling Phoenix" that Sima Hui spoke of. However, Xu Shu told Liu Bei that he was neither of them. He agreed to become Liu Bei's strategist and helped Liu counter an invading army led by Cao Cao's general Cao Ren. Cao Ren deployed his troops in an "Eight Gates Golden Locks Formation" (八門金鎖陣) outside Xinye, but Xu Shu pointed out the weaknesses in the formation and instructed Liu's general Zhao Yun on how to break it. Zhao Yun led his men to attack the formation and succeeded in breaking it and defeating Cao Ren. Xu Shu also accurately predicted that Cao Ren would launch a surprise attack that night after his defeat. Liu Bei defeated Cao Ren again in the night battle and forced Cao Ren to retreat.
