Li Xiu Xuan was born with white hair. Jiang Tian Feng, head of the Northern Emperor Sect of the Mayi Sect, found him in a cemetery and raised him for eighteen years. Their bond was like that of father and son. Before setting out on a long journey, his master left him these final words: if I haven't returned within ten days, go to Shanwu City and take over a funeral shop. On the eleventh day, Li Xiu Xuan stepped into that gloomy shop, and supernatural incidents began one after another: haunted houses, yin merchants, spirit mediums, and heirs to Lu Ban's book all became entangled in the affair. As he helps people ward off calamities and dispel misfortune, he also investigates the truth behind his master's disappearance. His journey to the northwest leads straight to a power struggle within the underworld bureaucracy. And the fate of the Mayi Sect, bound for a century by the Four Forbidden Things, awaits him to break it.
