There are many conspirators in history. These conspirators usually do things that harm others and benefit themselves, regardless of others' lives for their own benefit. Of course, these conspirators often come to no good end. However, if we say who is the first conspirator in history, some people may say Chen Ping, but I think Jia Xu is the first conspirator in history relative to Chen Ping. Jia Xu has betrayed his master three times, but he is different from other conspirators. The more he sells, the higher the price. Finally, he died at home at the age of 77, so I think it is understandable that Jia Xu called him the first schemer in history.

Jia Xu appeared in the Three Kingdoms for the first time 1. He served as the staff of Niufu under Dong Zhuo's account. In this sense, the first owner of Niufu was Dong Zhuo. But Niu Fu did not persuade Dong Zhuo under Dong Zhuo's account. On the contrary, he is bent on taking refuge in others. Later, he persuaded Li Jue and Guo Si and other generals to kill Chang 'an. Although he said he was revenging Dong Zhuo, he actually wanted to hijack Emperor Han Xian. It can be seen from here that Jia Xu has betrayed Dong Zhuo.

Jia Xu took refuge in Zhang Xiu for the second time. After Jia Xu led the generals of Xiliang into chaos, he went to Zhang Xiu to persuade Zhang Xiu, and Zhang Xiu defeated Cao Cao under the guidance of Jia Xu. Later, it was said that Zhang Xiu caught Cao Cao off guard when he committed adultery with his aunt, and killed all his sons and Dian Wei. However, in the battle of Guandu, Jia Xu suggested that Zhang Xiu unite with Cao Cao to deal with Yuan Shao. Later, Zhang Xiu surrendered to Cao Cao, and Jia Xu also successfully took refuge in Cao Cao. Although Jia Xu said he took refuge in Cao Cao for Zhang Xiu, he actually wanted to take refuge in Cao Cao himself, so he took Zhang Xiu with him. In this sense, he betrayed Zhang Xiu again.

Jia Xu's third master was Cao Cao, but when he worked under Cao Cao, he secretly took refuge in xelloss. Later, when Cao Pi and Cao Zhi competed for the position of Chu Jun, Jia Xu secretly helped Cao Pi win the throne. After Cao Pi ascended the throne, he was naturally grateful to him. Since then, Jia can be said to have spent his old age peacefully until he was 77 years old. From this perspective, it is understandable to call Jia Xu the first schemer.
