At the funeral, the whole village poured dirty water on Shen Suining, scolding her for killing the whole family and being the reincarnation of a broom star. But that night, seven soul lamps spontaneously ignited, and the deceased in the village knocked on their doors. The next day, the villagers knelt down in the mourning hall and burned paper to atone for their sins. She can see dead souls, but no one believes her. Until Zhou Yanbai, a foreign Taoist priest, broke in and discovered that she was the only 'keykeeper' who could talk to his missing master. When the ghost of Dry Bone Man tore open the dust of the mine disaster, and when Lin Xiutang's confession met the blood and tears of Mrs. Zhao, Shen Suining realized that she was not a disaster star, but the forgotten lock between yin and yang.
