Wang Xiaohai, a 35-year-old live-in son-in-law, is reborn in 2016, just as he wins five million yuan in the lottery. In his previous life, he married into the Chen family to pay for his younger sister's medical expenses, enduring seven years of humiliation. The Chen family drained his entire lottery fortune, while his wife, Chen Xiaoman, always took the side of her male best friend. Eventually, he was forced to leave with nothing. In his new life, Wang Xiaohai claims his winnings and uses his knowledge of the future to make profits in the futures market before decisively cutting ties with the Chen family. He helps his family overcome their difficulties, recruits talented people, saves a board member of Songlin College to expand his connections, develops the livestock industry, and builds his business empire. He fights back against malicious relatives, reunites with campus beauty Zhao Manshu, and finally sheds the label of a spineless live-in son-in-law to embark on a life of success and immense wealth.
