The fictional northern riverside city "Canghe City" has a mixture of good and bad people in the old city. Villages in the old city, night markets, flea markets, KTV, building materials businesses, and gray industries are mixed in ordinary city life. There is no fantasy or system. You will get injured if you fight, you have to hide from the police when you make trouble, and you have to pay the price at any time for being a gangster.
