I Was Laughed at When I Exchanged the Phantom Beast Species for the Dark Fruit!

This is Devil Fruit Era! It's an urban version of the One Piece world! Devil Fruit, Three Color Haki, Sixth Marine Style... However, there is no One Piece manga here! Until Xiao Ninglai, who was set in One Piece, awakened the devil fruit, and exchanged his own fantasy beast species for someone else's dark fruit. As a result, I was laughed out loud! Instantly ranked first on the hot search list! "Idiot, right?" "That's a species of phantom beast even rarer than the natural one!" "It was actually used in exchange for the Dark Dark Fruit, one of the top ten useless Devil Fruits with so low lethality that it exploded? Is your brain broken?" "..." "Holy shit! What is that?! The Dark Fruit can actually rob other people of their fruit abilities?!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
