Lin Fan traveled to the world of One Piece where the strong were respected, but unexpectedly found that he was a slave who could not be sold and was about to be disposed of! Fortunately, he got a weapon system. As long as he has a devil fruit, he can transform into weapons from all over the world! "Tianlong people... You are a bunch of scum, let me die! Burial in the sand waterfall!" "Blackbeard, do you know what it feels like to be burned by flames? No, I'm not referring to the low-level flames like Fire Fist Ace, but the real strange fire!" "Akainu, how is my Clear Sky Hammer? Do you feel good? Hahaha..." "Doflamingo, this is not a meat-cutting knife, but an Immortal Sword that can kill even gods!" "Big! Big! Big! Bigger! Garp, let's see which one is harder, your fist or my golden cudgel!" There is nothing that a weapon cannot solve, if... This novel and its characters are purely fictitious.
