Chen Wang, a scumbag at school, traveled back in time to the 1970s and became the doted upon silly grandson of the old Chen family. He pretended to be stupid and just wanted to do business in the future. The newest member of the Chen family is still a girl, and his status as the only child has not changed. However, he is fiercely opposed by his third cousin Chen Min because of the free study quota at the brick and tile factory. Chen Wang originally refused to study, but after hearing Chen Min's sarcasm behind his back, he made a bet to get the first place in the exam. The academic system attached to him became a help, and the former scumbag embarked on a counterattack in studying in the 1970s.
