Gao Wu, the Pistol Counts as a Gun Repairer.

Fast pace + passion + strategy + do it if you don't accept it + revenge does not take overnight I, Zhang Fan, am an ordinary, ordinary special forces king and martial arts master, reborn in the world of high martial arts. My talents are pistols, AK, Gatling, and Barrett. I should count them as gunsmiths. Zhang Fan said seriously: "As we all know, the monster among monsters has no pain!" Outside the border, in the alien territory, Zhang Fan held his hand, Gatlin: "Once a foreigner, always a foreigner, welcome mercy!" Zhang Fan held Barrett in the dark and looked at the traitor: "A traitor is a traitor. I am too lazy to say it. You don't deserve to listen!" Zhang Fan rode a war horse and walked around the land of China with an ak on his shoulder: "What a bullshit god's religion, don't hide, come out and let me take you to reunite with your god."
