Luo Yang transmigrates into the body of a prince of the Great Zhou dynasty, also named Luo Yang. From the start, he punches the woman who broke off their engagement and kicks his petty royal brother. Seizing his chance to soar free, he flees north to become the ruler of Beiliang. He wins the army's loyalty, develops the economy, and makes gunpowder to build a powerful military. When the barbarians invade? He wipes them out. When the old emperor falls gravely ill and his brothers begin fighting for the throne, he leads his army back to the capital and seizes power. Enemy states take the opportunity to invade? He destroys them too, establishes his capital in Beiliang, and unifies the realm.
