Enter the World of Pirates with Future Technology Systems

Why should others come to the world of One Piece and be able to save Nami, take in Robin, marry Vivi, train Perona, and conquer the Empress. And when it was my turn, Nami Robin was taken away by Luffy, while Vivi, Perona, and the Empress System refused to move. You can only marry a Hatsune figure. If someone else's system lacks anything, just use points to redeem it, weapons, skills, and everything is there. And it's my turn: I want the system system, the Sharingan, the Blade of Fire, and the Flying Thunder God. System: Sorry, what you want is unscientific. Then I want three-dimensional mobile devices, aircraft carriers, aircraft, tanks, and intercontinental missiles. System: No problem, here you go. I'll wipe it. Why did you give me a pile of paper? System: This is the blueprint, you can make it yourself.
