Ten years ago, a child's remark by eight-year-old Chen Balian ruined the cultivation path of the yellow weasel Huang Tianci, drawing the fierce ghost Liu Mei to massacre the Chen family. Huang Tianci sealed him as a village-guarding foolish child to avoid calamity, with an agreement to repay with his life after ten years. Ten years expired, Chen Balian's sanity recovered, and investigation revealed the tragedy was caused by the in-law He Jin. He Jin used evil arts to toy with the Liu sisters, attempting to use the Chen family's lives and Liu Mei's resentment to refine the longevity pill. Chen Balian uncovered the fifty-year secret, moved Liu Mei to destroy the pill herself, and eradicated He Jin with the help of Liu Longfeng, the python immortal, and Huang Tianci. After the war, Liu Longfeng ascended, Chen Balian changed his name to "Chen Wansheng", established a hall to go out as a shaman, and walked Yin and Yang together with Huang Tianci, executing justice on behalf of heaven.
