One Piece: the Evil Surgeon

I am a time traveler and a surgeon. On my first day in this world, I decided to go back to my old job - "treating" pirates. The evil dragon said that the fishmen were invincible, so I cut off his gills. Crocodile said there was no water in the desert, so I poured ten liters of saline into his veins. CP9 said that Six-Style was invincible, so I cut off Lu Qi's carotid sinus nerve - he wasn't dead, he just couldn't move anymore. Is Akainu's lava hot? As luck would have it, I blink a hundred times faster than his lava. The pirates told me to go to the New World, the navy told me to surrender, and the world government told me to stop. I don't even listen. I just want to open a chain hospital across the sea, and the signboard says: "The registration fee for pirates is doubled, the navy gets a 20% discount if they show their ID, and civilians - it's free." They said I was a very evil person. I'm just a doctor. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
