Shen Moyuan: On the surface, he is the most notorious "corpse collector" in the world, specializing in cleaning up the scenes of secret martial arts cases. He is indifferent, venomous, and greedy for money, but he actually has the bloodline of the "Soul Crosser" and is the last descendant of the two realms of yin and yang. The weapon is an ancestral black iron ruler, which can measure yin and yang and transfer the souls of the dead.
· Chi Lian: A powerful female ghost who has been sealed for three hundred years and is named "Chi Lian Demon Lord". She is not an innocent soul, but the master of the ghost realm who once caused a bloody storm and killed many people. It was sealed in the hand of Shen Moyuan's ancestor. Due to an accident, the core of his soul (a "ghost") accidentally entered Shen Moyuan's body, forming a "semi-symbiotic" state with him.
