In 1965, Lin Mo is reborn on the eve of his parents' murder and his younger sister's sale. On the surface, life in the courtyard house seems peaceful, but beneath it lurks the vile custom of preying on a family left without male heirs, along with the sinister power of folk traditions centuries old. He binds himself to the Yin-Yang Folk Traditions Revenge System, nourishing his arts with resentment as he drives out ghosts, summons spirits, and turns his enemies' strength against them. His foes are consumed by greed, joining forces to seize treasures and take lives. Now he will settle accounts with them one by one. Every accident is an act of vengeance, and every sudden death is heaven's punishment. Clues to finding his sister lie buried in a haze of blood, while the mastermind quietly pulls the strings behind it all.
