The night Shen Zhiwei put out the seven ever-burning lamps, the ghost king Yan Wujiu knelt down and begged for mercy, but he didn't know that the lamp in her hand was burning the soul contract of his biological mother. From then on, she wandered through the gap between yin and yang, using bones as a guide and blood as a lamp to suppress ghosts and search for the truth. Bai Jiuniang's Wangyou Tang, Lu Zhaoheng's blood-stained old handkerchief, and Ah Nuo's broken dreams all point to a taboo: she is not the person who extinguishes the lamp, she is the lamp itself. And Yan Wujiu's salvation is hidden in the seventh lamp that he lit with his own hands but never dared to extinguish.
