Shen Dai, the descendant of a declining family, was born with a pair of "yin eyes" that can see through the essence of evil things and the last thoughts of death, which is considered unlucky by the tribe. When she was still young, she received a strange will: to inherit the century-old ancestral home "Qingwu Garden" in the south of the city that no one dared to approach and which was rumored to be occupied by evil spirits. The condition was that she must become the "night watchman" of the mansion until her death. In order to find a place to stay and to find out the mystery of the family's decline, Shen Dai took over the mansion and dealt with the "residents" of different shapes and personalities in the mansion every night. She does not rely on spells to suppress them, but uses her Yin Eyes to discern their unresolved obsessions and grievances, resolve their knots one by one, and send them to death. As the "vindictive spirits" in the house are gradually appeased, the core of a huge curse spanning hundreds of years, involving secrets of the previous dynasty, the rise and fall of the family, and even an earth-shattering "love between man and ghost" gradually emerges. And the true identity of the legendary "Lord of the Haunted Mansion" with a green face and fangs who is feared by the world and what is waiting for her is far beyond her imagination. In the process of breaking the curse, Shen Dai not only restored the glory of her family, but also found her own destiny and strength.
