How to treat Lu Bu cursing Liu Bei before he died? Just saying.

Where there is faith on the battlefield, there is only temporary cooperation, not eternal alliance. Everyone is fighting for the world and living on the cutting edge. We can't be too simple Lu Bu once tried to harm Liu Bei. Liu Bei suffered a loss and was wary of Lu Bu. Moreover, Lu Bu is a military commander with high martial arts. If you blame Cao Cao, it will be bad for Liu Bei, so Liu Bei said malicious words, which is also the fuse of Lu Bu's death.
