Liu Bei was born in a poor family when he was a child, but he is a descendant of Han Jing by blood. Therefore, Liu Bei had an innate orthodox advantage in the troubled times when he was competing for profits with others at the end of the Eastern Han Dynasty. Although Liu Bei didn't like reading as a child, he liked to make friends. He is a hero, generous, and many people actively attach themselves to him. Therefore, Liu Bei was very prestigious in the local area at a young age, and soon recruited excellent generals such as Guan Yu and Zhang Fei.
After Liu Bei was defeated in the battle with Lu Bu, he led the army to take refuge in Cao Cao, who warmly accepted Liu Bei and arranged for him to be a shepherd in Yuzhou. Cao Cao saw Liu Bei's greatness with a pair of penetrating eyes and appreciated Liu Bei very much. They got along well and spent their honeymoon. Cao Cao often drinks with Liu Bei and talks about world affairs. He once drank wine.
At the banquet, I sighed and said that the heroes in the world today are only the ones who make you listen. ? He listened to Liu Bei's words, deliberately acting scared, because Liu Bei was attached to others at this time, and he didn't want to be too sharp-edged, but Cao Cao, who was sharp-eyed, saw Liu Bei's greatness.
After Yuan Shu, because his strength weakened, he wanted to lead his troops north to Yuan Shao and form an alliance with Cao Cao. In order to prevent Yuan Shu from going north, Cao Cao ordered Liu Bei to send troops to Xuzhou to intercept Yuan Shu, so as to prevent the situation of binary alliance. Guo Jia, the counselor around Cao Cao, heard the news and privately remonstrated with Cao Cao, thinking that Liu Bei was ambitious. If you order him to go out with the troops this time, it will be tantamount to setting the tiger free and swimming in the sea. Cao Cao thought about it, thought it was risky, and immediately sent someone to recall Liu Bei. But Liu Bei, who is very vigilant, has taken the opportunity to go far.
After Liu Bei arrived in Xuzhou, he betrayed Cao Cao and refused to lead the troops back after repelling Yuan Shu, with the intention of taking Xuzhou as a stronghold and plotting slowly.
After this incident, Cao Cao became more aware that Liu Bei was a threat and must be eradicated as soon as possible. At the same time, Cao Cao knows human nature well. He knows that Yuan Shao's slow personality will not act quickly, and he still has room for change. So Cao Cao decided to personally kill Liu Bei and then turn around and attack Yuan Shao.
