Wang Lei, a scumbag in the Department of Modern History, died suddenly during an exam and traveled through time to become Li Goudan, a poor scholar of the Dajing Dynasty. The father died long ago, the mother is weak, and she still has a baby girl who is about to become obsolete - the girl is Su Wan'er, the daughter of the former county magistrate's family. The people in the village laughed at him because he wanted to climb high despite not being able to pass the examination. Even the original owner spent his time peeking at the pornographic book, and all the young students failed in the examination in three years.
