The Five Dynasties and Ten Kingdoms period (907–979) was an age of turmoil in the Central Plains. Regional warlords carved up the land, the Liang, Tang, Jin, Han, and Zhou dynasties rose and fell in succession, and the Ten Kingdoms fought one another without end. The Khitan, who would establish the Liao, rose in the north, while Tibet and Nanzhao watched hungrily from the sidelines. The people suffered, and China plunged into its darkest era of division. The protagonist, Chen Yuan, is a modern graduate student in history who accidentally transmigrates to the third year of the Kaiping era of the Later Liang (909). He takes over the body of a down-and-out scholar caught up in the chaos of war in Puzhou. Carrying the Chinese Unification System, he has the complete history of the Five Dynasties and Ten Kingdoms, along with modern military, agricultural, and political knowledge, sealed in his memory. His mission is to bring the age of chaos to an end.
