Chen Yang, the night watchman of the funeral parlor, picked up a rusty copper bell while on duty, and actually tied up Shen Hongzhuang, a century-old ghost in red clothes. The fierce ghost wanted to devour his soul, but his hands and feet were bound by the iron law emerging from the bell. Chen Yang took advantage of the situation and set rules: he was not allowed to harm innocent people, he was not allowed to cross the line to cause trouble, and he was not allowed to sing in his ears in the middle of the night. Shen Hongzhuang regretted that she had ended up working for a mortal. But when she discovered the truth about Chen Yang's sister who died in the fire that year, the two were forced to join forces to fight against the evil cult organization behind the scenes that manipulated the supernatural events, and the true identity of the Soul-Calming Bell was revealed.
