Twenty years ago, to ensure his son's safety, Gu Shan entrusted the Xinsheng Group, which he single-handedly founded, to his sworn brother Pei Guodong for management. He lived under an assumed name as a university security guard, raising his son Gu Cheng alone. When Gu Cheng joined Xinsheng as an intern, Pei Guodong's son Pei Xiao repeatedly made things difficult for him, even beating Gu Cheng into critical condition and hospitalizing him on the day of the awards ceremony. In righteous fury, Gu Shan made his comeback, pulled surveillance footage, gathered evidence, and stripped the Pei family of all positions and shares overnight.
