After Liu Bei's death, the situation in the Three Kingdoms also began to be unstable. Even if Zhuge Liang tried to save the situation in his lifetime, he still could not change the decline of the Shu state. When the three points returned to jin, the history of the Three Kingdoms was also over. However, we still talk about many things between the Three Kingdoms, including about who Liu Bei is most likely to kill after unifying the world. If Liu Bei wins the world, these few will undoubtedly die, zhuge Liang knows it.
Zhuge Liang

First of all, Liu Bei unified the world, and the first person he wanted to kill was Zhuge Liang. Zhuge Liang's contributions to the Shu kingdom are indeed quite numerous, and it can be said that the Shu kingdom was established by Zhuge Liang's advice. In the continuous development of the Shu state, Zhuge Liang's prestige in the Shu state was also directly close to Liu Bei, which can be seen from the fact that after Liu Bei's death, Zhuge Liang soon dominated the Shu state. Therefore, when Liu Bei unified the world, the first person he wanted to kill was Zhuge Liang, who was the lord of gonggao.
Guan yu
The second person to kill is Guan Yu, who helped Liu Bei a lot as a brother in the process of fighting the world. However, Guan Yu's shortcomings have always been obvious, that is, pride. If after his own death, Liu Chan inherited the throne, then he could not control Guan Yu. Then before he died, he would definitely kill Guan Yu and let Liu Chan sit on his throne.
Ma Chao
The third Liu Bei wanted to kill was Ma Chao, who arrived at that time and made the Shu state's troops grow a lot. Although Liu Bei made Ma Chao a five-tiger general, he has always been secretly wary of Ma Chao. After all, although these troops were integrated into the Shu state, they were still loyal to Ma Chao. Therefore, in order for Liu Bei to stabilize his unified Jiangshan, then Ma Chao was the first person Liu Bei wanted to kill.
This is what happens after the founding of every dynasty, after all, emperors are selfish and need to stabilize their thrones.
