Jiang Yue transforms into the vicious teacher's wife who tortures the five-year-old male villain in the sadistic novel. As soon as she came through, she switched bodies with the villain Zaizai. She was forced to live in the body of a cub, while the villain used her body to take revenge on those who bullied him. Jiang Yue could only face Naimeng's face to stop "himself" from killing people and setting fires. The big one and the small one fight against each other's wits and courage every day, from hating each other to relying on each other for life. When her body was changed back, Jiang Yue found that the great demon king who would destroy the three realms in the future was tugging at the corner of her clothes and asking in a sweet voice: "Master wife, is my homework today to be a 'little guardian of peace'?"
