After his grandfather passed away, on the third night of Lin Du's vigil, the "Karma Pawn Shop" sign at the end of the old street suddenly lit up, with rules written in blood covering the wall. The child in the shroud handed over half a copper coin and said that his grandfather owed him three things: red clothes, glutinous rice, and a bride. Lin Du was forced to fulfill the contract, but found that each completed item would lead to deeper debts and more sinister things - a crawling shadow, a writing threshold, a lost sedan chair, and the "missing page of the Book of Hundred Tribulations" that appeared on the wordless tablet. Shen Zhao, a graduate student in folklore, came to visit with old cases from the fire ten years ago and pointed out that the rules were not decreed by heaven, but had been tampered with and stamped into effect. In the cellar accounting room, the bookkeeper was sitting upright, recording Lin Du's shadow and memory in the Baijie Book, and copies came one after another. He must redeem himself within seven days, otherwise he will become a "thing" in the pawn shop forever.
