Whole Family Transmigrated to the Republic Era

Lin Zhengguo, an ordinary young man from the 21st century, accidentally time-travels with his entire family to the Republic of China in 1937. Upon arrival, he is set up by the county magistrate to impersonate the leader of the Axe Gang, immediately facing death threats from the gang leader's wife, Feng Shuting. At a critical moment, his uncle, Ye Wenqiang—who also time-traveled and became the third-in-command of the Axe Gang—steps in to claim him as family, helping him survive the ordeal. To complete the system's mission of "becoming a Grand Marshal to win 100 million in cash and return to the original world," Lin Zhengguo is forced to take on the identity of the Axe Gang leader. However, he faces a usurpation plot by the second-in-command, Ding Haonan, who is the true culprit behind the assassination of the original gang leader and is colluding with inspectors to eliminate Lin Zhengguo. During this time, Lin Zhengguo must not only deal with turf wars against the Green Dragon Gang but also maintain his disguise while navigating his relationship with the gang leader's wife. When Ding Haonan rebels and the inspector arrives to apprehend him, how will Lin Zhengguo respond?
