I'm Really a Proper Gunsmith

Synopsis: Xu Yi, after becoming an NPC in the game, luckily returned to the modern world, and at this time the survival game Origin Project had just restarted. Wall-piercing bug monsters! Infinite skills! The only job transfer quest! Legendary pet incubator! Having received free NPC experience, there's nothing he doesn't know! When everyone is racking their brains to find high-level job transfer skill books, Xu Yi casually throws a Dominant skill to the resentful BOSS: “Do skill books of this type still need to be farmed?” Relying on the rich combat experience of an NPC, Xu Yi has opened his own game journey.
