After Being Fired from the Police Force: I Overturned the Evil in the City

I am forced to take off the clothes that guard the right path. I do not mix with evil, I only punish and trap evil. He devises clever plans and uses his own strength to deceive the underworld boss. I will collect the ill-gotten wealth, I will clear the territory where evildoers were committed, and I will definitely avenge any enemies. If you ignore me today, tomorrow I will let the evil have no place to be arrogant. I am Xiao Zhang, I am very arrogant and the godfather of all the gangsters in the city.
