Fantasy: Staring at Someone Who Is Pregnant

The protagonist feels a little childish, and after reading the previous part, I feel that the plot is okay, but there is one place that I don't understand. The protagonist trains the crew and tells himself that people with devil fruit abilities need to adapt to the sea water. A child with fruit abilities must do more than 1,000 push-ups and other things. The same goes for people without fruit abilities. I just want to know how people with fruit abilities can train when they encounter sea water. Isn't it because they have no strength? And how to do it? Is it done under the sea?

First of all, the author is a little confused, and there are errors in the plot. Secondly, the protagonist does not look like a time traveler. It is like having his memory deleted and becoming a native. His words, actions, and thoughts are very childish, not like the adults he once was. And then, when developing the fruit, he does not look like someone who has read a book. So I am more sure that he is not a time traveler. If he is a time traveler, then he should know that unless he can use his mind to do whatever he wants, He raised five or six small islands. Otherwise, controlling weapons in combat is just a low-level usage. He can completely train and control atoms, molecules, electrons, organs, blood cells, and develop mental shock, mind interference, brain wave interference, five senses control, bioelectricity interference, etc., But the protagonist did not think about it at all. He just wanted to control weapons. If the protagonist had read books, his parents would probably slap him every day.
