Lu Bu was beaten to powder. Since Lu Bu can obey Cao Cao, why can't he rule the world? After listening to Lu Bu, Cao Cao immediately turned to Liu Bei and asked, Is what Lu Bu said true? Liu Bei said: Don't you remember that Lu Bu betrayed Ding Yuan and Dong Zhuo? Lu Bu was furious at Liu Bei's words: Liu Bei is the most disloyal person. Finally, Cao Cao ordered Lu Bu to be taken down from the tower crane and executed. It can be seen from this passage that after being captured by Cao Cao, Lu Bu wanted to save Cao Cao's life with his surrender. Cao Cao immediately asked Liu Bei for advice. Liu Bei didn't answer directly, but said that Lu Bu had betrayed Ding Yuan and Dong Zhuo before Cao Cao executed Lu Bu. Lu Bu's life and death are in Cao Cao's hands. Who doesn't know that Lu Bu has become an honor seller? Of course Cao Cao knew, but he wanted to test Liu Bei with Lu Bu's death. Cao Cao is a hero. He regards Liu Bei as one of his own. When Liu Bei was at war with Yuan Shu, Lu Bu occupied Liu Bei's empire Xuzhou. Liu Bei took in Lu Bu. Liu Bei must hate Lu Bu. Although Lu Bu is the best in the Three Kingdoms, Cao Cao will definitely defeat him. Will he care about this capricious general and not rely on himself? Luo Guanzhong wrote a poem in Romance of the Three Kingdoms, depicting Lu Bu as the villain at that time. This shows that Lu Bu has the characteristics of a tiger: he is easily killed. The situation has been favorable to him, and he doesn't care whether Lu Bu is loyal to him. Cao Cao saw very clearly that Lu Bu could not be controlled and could not live in the world. Why did Cao Cao interrogate Liu Bei? Although Cao Cao doesn't care whether Lu Bu is loyal to him, he must know whether Liu Bei's figure is suitable. If Liu Bei is a big shot, what should he say? He should put aside personal grievances and intercede for Lu Bu. Cao Cao agreed to Liu Bei's request and let Lu Bu go. On the surface, Cao Cao gained the greatest benefit, because he gained the loyalty of the ancestors of the Three Kingdoms. But it was Liu Bei who got the most. He knew that Liu Bei begged for mercy, and Lu Bu was grateful to Liu Bei. Liu Bei begged Cao Cao to spare Lu Bu, but the best interest was Liu Bei. Of course, Cao Cao will not let Lu Bu go. Cao Cao released Lu Bu directly, and the other party sold the official for glory twice, unable to control the evil tiger. Will Cao Cao be on his side? When Cao Cao asked Liu Bei, he had made up his mind to kill Lu Bu. Since Lu Bu must die, why not use it to test Liu Bei? Once Liu Bei pleaded for Lu Bu, Cao Cao not only executed Lu Bu, but also took the opportunity to get rid of Liu Bei. Who is Lu Bu? Work for the real Dong Zhuo. Lu Bu was regarded as the enemy of killing his father by all courtiers. At this time, Cao Cao started a war for the world under the banner of Emperor Xian of Han Dynasty. Isn't it contradictory for Lyu3 bu4 to obey his own orders? When Cao Cao killed the shameless and unjust Lu Bu, he could gain loyalty as well as the loyalty of more just people. Why not Cao Cao? In 1999, Lu Bu was killed by Cao Cao. A year later, he and Yuan Shao fought in Guandu. He was weaker than Yuan Shao. When Cao Cao comes to power, will he kill this generation because of Liu Bei's words? That is to say, Cao Cao decided in his heart that Lu Bu should get this result. He just wanted to test Liu Bei with Lu Bu's life and death. After Lu Bu's death, Cao Cao was stronger than Liu Bei, and Liu Bei had to obey Cao Cao. But after the war broke out between Cao Cao and Yuan Shao, Liu Bei turned to Yuan Shao. The situation is that Yuan Shao is stronger than Cao Cao, and Liu Bei thinks that Lu Bu is unfaithful and unjust. But isn't he also a snob who follows the strong? Loyalty to the Three Kingdoms, Tang, is an excuse to win people's hearts. Liu Bei evaluated Lu Bu and listened to Cao Cao's words, but he was only dispelling Cao Cao's doubts about himself. After Yuan Shao's defeat, Liu Bei took refuge in Liu Biao. Then they took Liu Bei to Runan.
