On the journey back, Lü Dai passed by Baidicheng (in present-day Fengjie County, Chongqing) and met Sun Quan's ally Liu Bei, who was leading an army to seize control of Yi Province (covering present-day Sichuan and Chongqing) from its governor Liu Zhang. He saw that Liu Bei's army was in disarray and had lost about half their total number of troops, and felt convinced that Liu Bei would not succeed in conquering Yi Province. After returning to Jiangdong, he told Sun Quan, who in turn asked his adviser Wu Fan (), who had previously predicted that Liu Bei would conquer Yi Province. Wu Fan replied: "My prediction is based on Heaven's will. What Lü Dai saw were the actions of people." Wu Fan's prediction came true as Liu Bei did eventually conquer Yi Province by 214.
