In 1968, in the detention room of Yau Ma Tei, Hong Kong Island, plainclothes criminal police officers were framed by Yan Tong. A slap in the face turned into a serious injury, forcing Uncle Guang to give up his position as the detective of Kowloon City. Brother Gao Qiu came in to tell the news, please don't let this old thing fall into my hands. The professional auxiliary system is available, and the body is filled with natural divine power. I want to sit in this detective's seat myself. When you are on duty, you have to be the most ruthless. Yan will be waiting with you.
