Liu Bei borrowed the Jing Province from Eastern Wu, but the King of Eastern Wu, Sun Quan, soon regrets and asks him to return at once. Liu Bei claims he will return it after conquering Xichuan, which he never really plans to.

Zhou Yu, the supreme general of Eastern Wu, is furious at Liu Bei’s act, hence plans to siege Jing Province. He sends troops to Jing Province and claims that those are the troops he sent to help Liu Bei conquer Xichuan. Just before he thinks he will succeed, he is surrounded by Liu Bei’s army and gets kicked out hard. Filled with regret and fury, he dies soon after that.
