I am Garp of the Great Voyage

Mu Chen, who can be called the unluckiest guy on earth, traveled to the pirate world and found that he had turned into a fifteen-year-old boy named Monkey D. Garp, who knew nothing about the pirate world. Fortunately, he had a system to assist him, which became the cornerstone for him to reach the top.

This is a magnificent era, with strong men from all walks of life advancing hand in hand, Roger, Rayleigh, Whitebeard and his Zero Squadron, the Red Earl, the Golden Lion, the Eight Treasure Marines, the World Destroyer…

This is a story about a different Garp who wants to catch pirates and inspires him to become the strongest navy!
