Qiao Zhou, a modern social animal, accidentally traveled to a strange ancient world and became a poor student despised by everyone in Qingwu Academy. At the beginning, he was facing the crisis of being dropped out of school, but he was accidentally bound to the "student master system" and gained the ability to "rewind time" - if he fails in the exam, he can try again.
Faced with the bizarre teaching materials that will be integrated, Qiao Zhou has to study hard, and also has to deal with the devilish training of the strict instructor Su Yan. He makes friends with various classmates such as sword cultivators, female doctors, and mechanics, and continues to grow in the Bible debate competition, water control tasks, and experience with monsters.
