In the myriad domains of Xuanzhou, rival kingdoms stand side by side, while the immortal sects lord it over them, treating mortal dynasties as vassals. Zhao Heng, the ninth prince of Great Yong, loses the struggle for the throne and is exiled to the desperate frontier of Xiao Pass, where he awakens the ancient Human Emperor Seal. He does not seek personal immortality. Instead, he follows the Great Way of the Human Emperor. Starting from a lone city, he gathers scattered troops, brings peace to the people, and draws together the fortune of the land. He wages war on the barbarian tribes, crushes the great clans, destroys the feudal lords, and subdues the immortal sects, forging an undying immortal dynasty amid the chaos.
