To survive, the soul-devouring water demons of the Eastern Sea must consume the pure souls of young boys and girls every month. Mo Chen, chief coroner of the Imperial City Bureau and a practitioner of necromancy, investigates a series of bizarre child disappearances and skeletal remains. With keen insight, he identifies traces such as the cold, soul-devouring aura left on the bones and signs of special spatial magic, then tracks down and deals a heavy blow to the demons, disrupting their hunts and putting their survival at risk. Furious, the water demon clan leader, “Youhai,” plots revenge and kidnaps Mo Chen’s most precious daughter, the half-demon Mo Li.
