A pirate on the high seas kidnaps a Celestial Dragon!

Having transmigrated to the world of One Piece and bound to the "Strongest Bandit System," Qi Bai receives rewards for engaging in bandit-like behavior. Left with no other choice, he is 'forced' to become a bandit, and so...
"Redhead, your daughter Uta has been kidnapped by me! You don't want anything to happen to her, do you?"
"Whitebeard, Ace is in my hands now! What price do you think I should offer to ransom him back!"
"Garp, your grandson Luffy is in my hands! You don't want to bury your son, do you?"
"Kaido, your daughter Yamato is in my hands! You don't want to have a grandson so soon, do you?"
"Five Elders, the Celestial Dragons have been kidnapped by me..."
"..."
In the Holy Land of Mary Geoise, Qi Bai, who had just dealt with Im, lit a cigarette: "Don't rush, let me finish this last job, then I'll go to the next world to have some fun!"
