Unable to Attack, I Used a Barrier to Change the Other World

The plot description is a bit like a running account. The most important thing is that the protagonist has no consciousness of being a time traveler and does not think carefully about how to develop his own barrier ability. Instead, he struggles for dozens of chapters with "I don't belong to this world and I feel like I can't fit in." Later in the plot, there are some emotional scenes where the team fights for women. They do it like this on a daily basis, and then they do it like this during battles. Aren't they afraid that the team will be wiped out? I can only say that it is very boring. At present, it seems that the protagonist obviously has unique abilities in the world, and the barrier fruit is obviously very powerful, but he has no thinking ability like a kindergarten child. He doesn't think about developing abilities, and only knows how to resent all day long👎
