Lü Bu was recognized as the first fierce general in the Three Kingdoms period, and whether it was in the evolution or the main history, Lü Bu's martial value was more convincing. However, although Lü Bu was brave and fierce, his character was not very good, and he initially recognized Ding Yuan as a righteous father, but he killed Ding Yuan for the sake of profit, and then recognized Dong Zhuo as his righteous father, and later killed Dong Zhuo. Captured by Cao Cao in a great battle with Cao Cao, when Cao Cao hesitated whether to behead Lü Bu, there was Guo Jia next to him, so why did he ask Liu Bei?

At that time, Lü Bu could not die without death, and he thought that he could fight with Cao Cao, and while Cao Cao attacked Liu Bei in Xuzhou, he secretly attacked Cao Cao's stronghold of Yanzhou from the rear and occupied a large area of Yanzhou. However, Cao Cao's army returned to the division and beat Lü Bu out, and the cornered Lü Bu defected to Liu Bei, and Liu Bei kindly took Lü Bu in and stationed Lü Bu in Xiaopei. However, Lü Bu's poor character was once again revealed, and he took Liu Bei's Xuzhou and became the boss himself. Although Liu Bei was very angry, he did not have the strength to compete with Lü Bu, so he had to seek perfection. And Lü Bu also saved Liu Bei once, and he used the strategy of shooting at yuanmen to defuse the war between Yuan Shu and Liu Bei.
After Cao Cao reorganized his troops and horses, he naturally still wanted to capture Xuzhou, and Lü Bu was not yet Cao Cao's opponent, and was eventually captured by Cao Cao. At that time, the general around Lü Bu was brought forward, and Liu Bei stood by Cao Cao's side, and Cao Cao asked Liu Bei if he wanted to kill Lü Bu. According to common sense, Cao Cao should have asked guo jia, the first strategist, not Liu Bei.
In fact, this is Cao Cao's plan, Liu Bei has always been known for cherishing talents, he knows that Liu Bei has a vendetta against Lü Bu, he first showed that he cherished talents, he could not bear to kill Lü Bu, let Liu Bei open this mouth, which means that he loves talent more than Liu Bei, and the people of the world will be more willing to defect to Cao Cao instead of Liu Bei. In addition, Cao Cao knew in his heart that Liu Bei wanted to kill Lü Bu, and deliberately sold this person to Liu Bei, also trying to win Liu Bei over. This seemingly casual question is actually a very clever hand.
