Sima Chun, who came back from the army to work, accidentally won a billion-dollar prize. He wanted to live a happy life in seclusion, but his wife's cheating partner accused him of misappropriating the company's trade secrets and was taken away by the police station. In order to clear the unjust case, he hired a high-priced lawyer Chen Yuzhu. During the relationship, the two fell in love with each other. Before his case could be concluded, he was approached by Ou Ping, the former head of the army, who asked him to investigate a new virus case as an informant. Since the biological virus case related to people's health and national interests, Sima Chun was obligated to accept the task and began to lead a different life. In order to hide his true self, he had to change his good image of abiding by the law. From then on, he started fighting, mixed into the underworld, and practiced black boxing. He repeatedly misunderstood others and made his parents and family suffer unjust injustice. He endured the humiliation and endured all kinds of hardships and dangers. He played for others. He was disrespectful to the world, lived a luxurious life of feasting and entertainment, and ignored his lover. He also opened a company, used private funds to invest and recruit employees, secretly collected clues, and finally successfully found criminal clues, cooperated with the police to crack the case, and finally cleared his own stigma. He secretly helps poor villagers, collects clues about them, punishes lawless elements, and allows corrupt officials and evil elements to receive the sanctions they deserve. During this period, he secretly funded the construction of his hometown, vigorously developed rural education, and built an entertainment center for the elderly so that every villager could have a secure retirement. Eventually, his hometown will become a model village in the province.
