Why does Kprusoian's trekking do more good than harm to the navy? In my opinion, it is indeed correct for Kprusoian to let him walk and fly, because Luffy's father is the leader of the revolutionary army, his grandfather is a naval hero, the leader is one of the four emperors with red hair, and his master is Raleigh. In addition, Luffy has many pirates, all of whom are famous masters, so the navy may not kill Luffy for the time being because of his background. Moreover, keeping Luffy can use him to defeat many pirates, such as the king of the seven seas and five seas and the four emperors, which is beneficial to the navy.
Kprusoian in One Piece is a naked man eating sparkling fruit. He can emit laser from his fingers and kick his legs at the speed of light, or he can turn into light and move at the speed of light.
At this time, his body is made of light and will not be attacked by any outside world.
In the universe, the speed of light is the fastest, traveling at a speed of 300,000 kilometers per second. Kprusoian became a naval general with his invincible attack, defense and maneuverability. He never speaks gruffly, speaks slowly and is independent of the world. This is probably a sign of absolute confidence. Well, what a handsome adult.
In addition, Luffy has now assembled a team to formally fight Cardo and Aunt. Even if Luffy can't do Cardo and others, it will greatly weaken the strength of the four emperors, which is the best ending for the navy. Therefore, it's right for Kprusoian to let it fly on foot and ensure that the navy can reap the benefits of fishermen. This is why the country can't find a navy. )
The above is purely a personal opinion, and there are different opinions. Welcome to discuss.
