Once Upon a Time in the Northeast: a Policeman's Road to Revenge

Don't think this is a simple urban game. The script I envisioned was to successfully become an anti-drug policeman and then find Lin Yi and avenge his adoptive parents, but the reality backhand directly tore the script to pieces. In the past, brothers met by strangers and were in opposing camps; strong enemies came one after another, and it was normal for one to fight against many. Friendship and choice are before you, and if you make a slight mistake, you will be doomed.
