On the other hand, Yuan Shu was angered by Lü Bu's betrayal, so he sent his generals Zhang Xun () and Qiao Rui () to lead an army to attack Xiapi from seven directions in collaboration with the White Wave Bandits led by Han Xian and Yang Feng. Lü Bu was in a disadvantageous situation, with only 3,000 men and 400 warhorses. He was afraid that he might not be able to resist Yuan Shu so he blamed Chen Gui for giving him poor counsel. Chen Gui, however, thought that Han Xian and Yang Feng were not genuinely loyal to Yuan Shu, so he advised Lü Bu to persuade them to break their alliance with Yuan Shu. When Lü Bu attacked Yuan Shu's forces, Han Xian and Yang Feng defected to his side. Yuan Shu's troops were defeated and Lü Bu pursued them until he reached south of the Huai River.
