Human beings can be divided into two kinds: ordinary people who work for the living, and the undead who work for the dead. For the undead, their lives are dedicated to fulfilling the final wishes of ghosts who died with regrets. As for Baili Dengfeng, he has one and only one destiny in this world: to find his long-missing wife Ruyan. During his quest, Dengfeng makes acquaintance with Jia Xuan, whose family was murdered and is yet to be avenged, Liang You who is cute, naughty and adores him very much, and Liang Yuan, who simply doubts everything neurotically. After a series of events, he also learns of the existence of Spirit Masters and Spirit Slaves, and gets in touch with a mystical organization named "Spirits Expelling Order". With more and more mysteries being unveiled, the truth is drawing closer and closer to Dengfeng, who perhaps would rather not face the whole of it.
