As a man of science and engineering, Wang Yu was abandoned by a gold digger and had a car accident. He accidentally traveled through the confusion of the Dakang Dynasty and woke up to find himself lying in a thatched hut. At this time, the population of Dakang was declining. In order to increase the population, the village chief summoned unmarried strong men from the village to choose a wife. Wang Yu fell in love with Li Xiruo at first sight and became husband and wife. However, Wang Yu, who was originally a spendthrift, was penniless. Coincidentally, the bully Liu Youcai came to collect debts. With his rich experience in the future, Wang Yu continued to make a fortune and led the villagers to fight against the bully Liu Youcai and the young man Liu Jianye. He invented a series of novel products and policies, which changed the national fortune of Dakang.
