In the sixth year of Zhongping, the fate of refugee Dugu Xin was rewritten by the "Cao" flag. This stranger from the Northern Zhou Dynasty had a past as the head of state in three dynasties, but he could only start as a corps commander in charge of five soldiers. He integrated the bravery of the Northern Dynasty cavalry into the spear skills of the Han army, and used the experience of commanding thousands of armies to polish the lower ranks. In the late Han Dynasty when food shortages and wars were intertwined, he quietly accumulated strength under Cao Cao's account. From half a piece of millet cake on the Yellow River tidal flat to the cold light blade on the battlefield, Dugu Xin's development journey is a hard-core collision between the famous alien generals and the troubled times of the Central Plains.
