Xueyue Library, the Group Pet Is Actually the Rule Book

Late at night, the closing bell rang in the library of the private St. Mary's Women's College. The librarian Bai Wei disappeared into the underground warehouse, and dark red liquid seeped out from the cracks in the door. The next day, transfer student Ye Wanqing entered the school with a black cat, and a gear tattoo quietly appeared on her neck. The rule written in blood appears: "Those who violate it will become part of the book collection." Student Council President Jiang Li discovers a secret connection between her grandmother and the seven teachers who disappeared thirty years ago, while the black cat whispers that the blood moon is coming. As the teacher changes one after another, the pocket watch runs backwards, and the shadows merge into gears, the truth is revealed layer by layer - Ye Wanqing is the last "night watchman", but Jiang Li is the rule of life itself. When the silver knife pierces the heart, the academy collapses and reincarnation restarts. The school bell rang again, seven figures came over, and the shadows on the ground quietly closed into a complete gear array.
