The ancient diviner Long Wenxin, to save the world, scattered his divine powers—the all-knowing eye that could see through the secrets of heaven, the healing heart that could heal the dead, and the invincible battle spirit—into twelve fragments, creating the twelve most powerful families of the era. Sixty years later, she returns as a mortal with white hair reaching her shoulders and black silk covering her eyes. The iron-faced commander Xiao Che, ordered to monitor her, gradually becomes her chief bodyguard and most devout follower. This time, she will not only reclaim the fragments but also redefine the rules of this world.
