Review Detail of Vandumbo in I'm Luffy (Hiatus)

If you are a fan of One piece, I don't advise you to read this story. If you want a OP protagonist, and Luffy x Makino (and maybe Nami idk) and lemon, then this story may interest you. The MC reincarnated as Luffy (no surprise here) but I don't understand where this is useful: -MC can create any skill he want(like immunity to water, haki, teaching...) -MC is OP I don't understand WHY the author make the MC reincarnate as Luffy, it as no use to the plot except for the part: Makino and Luffy are acquainted before the MC reincarnate Ah, about that, the MC (in the body of the child luffy) will make love with Makino. And make her OP as well (kind of) and recruit Zoro (and teach him haki) It wasn't easy to bear the story until the moment where Luffy brainwash Baggy with his conqueror Haki (I stopped here)
