A Girl Who Found a Gun? but I Am the Legendary Gun King!

[Single female protagonist] [Urban high martial arts] [Gun Girl personification] [Decisive killing] [Smooth writing] [Absolutely beautiful] Wu Shi traveled through time and entered a world of gun girls. In order to resist the invasion of the demonic plague, humans created weapons that can take the form of humans - Gun Girls. Gun Girls fight side by side with gunmen called "Hunters" to hunt down demon leaders and earn bounties in the guild. But Wu Shi, who felt that the hunter's job was too dangerous, chose to use Goldfinger's ability to repair Gun Girl, and disguised himself as a famous perverted mad mechanic in the guild. But in fact, he was taking advantage of his position to save those gun girls who were about to be executed. —— But after he brought back the gun girl "Kana Ayai" who was so disabled that only the gun was left, he was brutally liquidated by the organization and almost lost his life. But he also received a golden finger upgrade called "Legendary Gun Modification King", which allows him to modify the Gun Girl at will according to his own preferences! Thus, the most mysterious and dangerous hunter in the Gunslingers Guild was born. Because... No one knows what model the gun girl in Wu Shi's hands is! ! ! From rifles and carbines to shotguns, sniper rifles, heavy machine guns and even RPGs! As long as you can't think of it, there is no way I can't do it! —— "Master, don't put weird things on me." "But this is a sight." "Master, could you please pull that off?" "But this is the barrel of a gun." "Master, can you change me into a heavy machine gun again?" "Why?" "Because then I'll look more aggressive." "..." "Can you be more serious?"
