The real reason why Xu Shu left Liu Bei was not that Cao Cao tied up his mother, but that he saw through Liu Bei
Liu Bei escaped death after the prancing horse Tanxi, by chance met Mr. Shuijing, for the Han family, Shuijing recommended Xu Shu to Liu Bei, Liu Bei finally had a strategist, in the face of Cao Ren's army pressure, Xu Shu showed his talent, skillfully cracked Cao Ren's formation, and captured Fancheng, won Guan Yu Zhang Fei's respect in a battle, but unfortunately the good times did not last long, Xu Shu found Liu Bei's true face, he did not want to help the Han family, but wanted to make his own achievements as emperors
At the same time, Taoyuan's three alliances are also to get ahead, which is completely different from Xu Shu's Renjun, it just so happens that Cao Cao is also attracting talents at this time, Cao Ren's defeat made him pay attention to Xu Shu, Xun Yu even said that Xu Shu's talent is several times better than him, hearing this, Cao Cao wanted to take Xu Shu as his own.
Through Cao Cao's kidnapping of his mother, Xu Shu pretended to be reluctant on the surface, but in fact, he quickly left and went to join the stronger Cao Cao, and he felt that Cao Cao was more real and Liu Bei was more hypocritical, but he felt that he was really sorry for Liu Bei, so he returned to Ma Zhu Ge, whether Liu Bei is a true benevolent monarch or a hypocrite, let Zhuge Liang judge, therefore, Xu Shu officially left Liu Bei and brought his friend Shi Tao with him
The plot of Xu Shu's mother disapproving and hanging herself is mostly recorded in romance, Xu Shu actually made the right choice, and it is really a bit beautified to enter Cao Ying's camp without saying a word, after all, Xu Shu did it in the imperial history, which is equivalent to the emperor's secretary, and contributed to Cao Pi becoming the emperor, and when Cao Cao's army attacked Xinye, Liu Bei took the people to flee with him regardless of the life and death of the soldiers and his family
And after Zhao Yunqi went in and out and brought back Adou, Liu Bei slammed Adou in order to prove his love for talent, which played a role in attracting people's hearts, and when Adou was sick and had a high fever, Liu Bei only cared about winning over Feng Chick, completely ignoring Adou's life or death, Liu Bei seemed to be benevolent and loving the people, but in Xu Shu's eyes, it was indeed false and hypocritical, on the contrary, Cao Cao's real traitor made Xu Shu appreciate it even more
