Yang Guangshu, the owner of a modern farm, accidentally traveled to 1977 and was bound to the "Shuttle Between Worlds System". At the beginning, he was mistakenly regarded as a gangster and was forced to become the stepfather of the widow Wang Chunmei and her three daughters. He used modern knowledge to make a bucket to solve irrigation problems, and hunted wild boars with his bare hands to improve his life. He used the system to travel back and forth between 1977 and 2024, exchanging wild game and antiques for modern materials and wealth.
