Ling Xuan, a college student who appears to be lazy and undisciplined, turns out to be an executive in charge of the yin and yang order of Hades. He is ordered to guard the human world and suppress supernatural events that get out of control due to "law cracks". He disguises himself as a human, but possesses an almost incomprehensible source of power - devouring all things and controlling nothingness.
Xie Yunlin, the heir to the century-old Celestial Master family, has a strong spiritual vein and a cold personality. He is the guardian of order in the world. The two met due to a series of supernatural incidents on campus. From testing each other to being forced to conclude a blood contract, the two worked together to solve a series of bizarre cases: ancient mirrors eating souls, yellow immortals seeking seals, time loops, and corpse puppets in deserted villages...
However, as the investigation deepened, they discovered that behind the incident were old grudges from the massacre twenty years ago, and a shocking conspiracy that the rift between Yin and Yang was about to completely collapse. What shocked Xie Yunlin even more was that he gradually realized that this seemingly ordinary "contract partner" around him had a true identity and power far beyond imagination, and was actually the key to maintaining the balance of the world.
