Zhao listened to the slanderers. Guo Kai may also be a typical villain in the history of our country. When he was serving Zhao's father, Zhao, he accepted bribes and told the old general that Lian Po could still eat, but he had to go to the toilet three times a meal. As a result, the old general Lian Po was not reused and eventually rebelled and fled to Wei. This time, Guo accepted a bribe from General Wang Jian and told Zhao that Li Mu and Sima Shang were close to each other on the border and might rebel. Zhao, the pig teammate, never thought about the authenticity of Guo, so he directly asked Li Mu and Sima Shang to unload their troops and let Yanju replace them. However, Li Mu knew what the result of defection would be, and he also knew that Zhao could not fail again, so he violated the orders of the king of Zhao on the grounds that he would be absent, and his teammate Zhao believed that this was evidence of Li Mu's rebellion. He didn't know the battlefield veteran, but sent someone to set a trap and killed General Li Mu with trickery. As a result, it is conceivable that Zhao was defeated and killed.
