The plot of the first chapter of the Romance of the Three Kingdoms was as follows: During the Three Kingdoms period, Cao Cao led an army to attack Liu Bei's Jingzhou. Liu Bei's wife, Mrs. Gan, and her son, Liu Chan, were hiding in the thatched cottage, preparing to use bows and arrows to defend against Cao Cao's attack. However, Cao Cao's general, Zhang Liao, suddenly led his troops outside the thatched cottage to rescue Lady Gan and Liu Chan and fled to Jiangxia County with them. After that, Cao Cao continued to attack Jiangxia County but was defeated by Liu Bei and the others. Liu Bei took advantage of the victory and occupied the base of Cao Cao's army. In the process, Liu Bei got to know Guan Yu, Zhang Fei and the others and formed a brotherhood with them. In the end, Liu Bei defeated Sun Quan's allied forces in the Battle of Red Cliff and became the overlord of the Three Kingdoms period.
