Upon hearing Liu Bei had taken Yi Province, Sun Quan sent envoys to ask him for the return of the commanderies in southern Jing Province, but Liu Bei said: "Jing Province will be returned after I take Liang Province." Sun Quan was furious when his envoy reported Liu Bei's words, and he sent Lü Meng and Ling Tong with another four officers to retake southern Jing Province. After Lü Meng and his colleagues captured three commanderies, Liu Bei returned to Gong'an County and prepared to seize back the three commanderies by force. However, he eventually arrived at a border treaty with Sun Quan when he heard Cao Cao was planning to attack Hanzhong Commandery.
