Funny, on the base of the Romance between 3 Kingdoms. Liu Bei, Cao Cao, Sun Quan are actually Chief warlords of 3 Kingdoms, which are determined by a major event "Red Boulder Battle", where Liu and Sun's joint force won Cao's, and a famous battle where the weak won the strong. Zhuge liang is the prime minister and the major brain of Liu, who laid his place in Bowang Slope battle against Cao Cao's general Xiahou Dun, who ate his own eye when he caught a arrow in one eye during the battle saying he won't lose his flesh.
