Pirates: a Bounty Was Put on the Head by the World Government at the Beginning

Zell has been in the world of One Piece for five years. As a time traveler, he has always thought that he was the son of destiny. He felt that since he came to this world, he should work hard to end this fucked up era. However, he was wrong. After being restricted by the world government again and again, his fiery heart became cold. The Navy actually has to look at other people's faces to catch pirates, so I'm not a Navy man in vain. In this case, I don't want to be a navy. Being a pirate is also a good choice. Years later, the Zell Pirates have become a threat to the world government, and the fiercest battle for supremacy ensues. PS: In the early stage, the protagonist relies on physical skills to fight. In the later stage, he may be given a Devil Fruit. As for which Devil Fruit it will be, the author is still considering it.
