My name is Zhang Ming. When I was still in the police station, I met Qin Meng, Nan Zhi and others. However, I lost my right hand during an activity, and my combat partners were also injured to varying degrees. However, those "criminals" escaped the sanction of the law. After this operation, we resigned from the police and the five of us set up our own detective agency - "Punish the wrongdoers in our own way." After that, we received cases of disappearances and other cases.
