First:if you at some point get annoyed at mc, because he is too dense, or does something that could make you stop, read chapter 66, as long as author doesn't replace it with a normal one, it contains a bit of explanation to what, and why happened, but don't read it too early, before chapter 10,or there will be spoilers, now about tge story.
Characters are great, world is detailed, and makes sense, power systems are good, and precise, and mc, while being op, isn't boring, and not just because there is always someone stronger, but because he knows what is he doing, he has a target, and tries to get to it, overall, don't drop, the problems usually are for a few chapters at most, problems with the book, not the problems of mc
