Three Kingdoms: I Was Emperor from the Start

A modern special forces soldier is reborn and transmigrates, landing in the late Eastern Han dynasty in the body of Yuan Shu, the Skeleton King, who has just declared himself emperor.

There is no way I'm going down! Watch me crush Sun Ce and seize Jiangdong, force Lu Bu to marry off his daughter, defeat Cao Cao and kill the emperor, capture Yuan Shao and take the north, turn the tide, and unite the realm!
