Folklore investigator Shen Gui was expelled from the school for violating taboos and returned to his hometown. He found that the "rules" in the village were coming to life - paper figures knocked on the door in the middle of the night and asked for birthdays, tablets in the ancestral hall moved by themselves, and humanoid mushrooms grew where the funeral procession passed. In order to survive, Shen Gui activated the ancestral "Hundred Skills Book", which can be combined with templates of various weird professions: paper maker, Feng Shui master, coffin maker... But every time it is used, the life balance will be reduced, and it will be seen by everyone. He rescued the little girl Xu Xiaoman who was haunted by paper dolls. A causal bond was created and he must help her get rid of it completely. However, when Shen Gui discovered that Xiao Man's bad luck was a trap deliberately designed by the village chief, the Karmic Deed asked him to protect the mastermind behind it. At the same time, there were only seven days left in his life, and a greater crisis came: the whole village began to turn into paper dolls one after another, and only by sacrificing and sinking can the curse be lifted. Tonight, Shen Gui has to make a choice: go against cause and effect and suffer the backlash, or use his remaining lifespan to activate the ultimate template and perish together with the entire village's folklore spirits? But the close relative who was accidentally injured by his own hands suddenly appeared in front of him and handed him an old yellowed photo - in the photo, he saw the truth that he would die in the next three days.
