Zichuan Xiu, whose real name is Qin Zhao, is the only surviving prince of Dongchuan after its fall. The enemy general Zichuan Lie adopts him and names him “Zichuan Xiu,” meaning “the humiliation of the Zichuan family.” He grows up in the enemy nation, joins its army, earns military distinction, and rises step by step to become a great general. Twenty years later, when the enemy forces under his command reach the gates of Dongchuan’s former capital, he opens them, only to be greeted by his own banners. Only then does his adoptive father, Zichuan Lie, realize that this “humiliation” has never forgotten his bloodline.
