Xiao Musheng, a poor college student, lives in the haunted house 404. He accidentally activates an ancestral jade pendant and gains "spiritual vision" ability, which allows him to see undissipated spirits. In order to earn the bounty, he was forced to jump repeatedly between the Yin and Yang realms, live streaming murders, murders of wealthy families, etc. Every time a case is solved, a crack in the jade pendant will be healed and new abilities will be unlocked. When the last crack disappeared and the truth about his parents' death finally surfaced, Xiao Musheng also embarked on a journey to find the final answer.
