They Are All Goods from the Underworld. You Call This a Weapons Master?

Parallel world, spiritual energy revives. Su Wei, who awakened the blacksmith profession in school, has pitifully low attack power. Just when Su Weidu no longer had hope for himself. Su Wei actually awakened the Invincible Blacksmith System. But the system doesn't seem to be very reliable, and the things it creates are too hellish. "What the hell? Why did you give me a kitchen knife? You want me to take this thing to the battlefield?" "You call a kitchen knife the best knife in the world??? Don't tell me that it cuts iron like clay, blows the knife and breaks hair, and can cause infection???" "This dog leash... You call it a soul-binding rope? Can it disable spiritual energy? Cowhide, cowhide!!" "You call this tattered rag the queen's veil? Which queen goes out with this thing? Can this thing be disguised? Not to mention that friends can't see it? His father can't tell the difference when he comes?" "This toilet lever is still stained with semen. Ugh... Is this called the light of courage? Ugh... I believe you. It does require courage. This thing has a mental attack!" … "System, I know you are awesome, but compared to your awesomeness, you make me feel sick." A veritable master of weapons from the underworld.
