After Jiang Li, a gold medal lawyer in his previous life, was retaliated and died, he traveled through time and became the underworld prince of Longhu Street. However, he insisted on upholding justice with the law and opened the Truth Law Firm. He led his younger brothers to handle domestic violence, sexual assault, abduction and other cases one after another using the method of "solving first and then fighting", fighting against the evil forces and their protective umbrella, and finally bringing the criminals to justice and continuing to provide justice for the oppressed.
