For those who say this is similar to Shitara Slime Datta Ken's tensei, then you are right, but after I read it only the beginning is similar to Chapter 1-10 maybe? Not very similar, obviously. I suggest reading before comment or review.
Let me explain once again, at first I thought this was not interesting, this is just ordinary because there are too many time passes but the longer the novel gets more epic, I'm serious, you have to try.
