The harem: it's good, but going to the end it goes downhill, almost exploding, at least the author tries to conquer girls in some almost realistic ways, I say almost because at least he tries to explain to his women why he wants a harem, and When I say try, it means that it fails, but I won't be demanding either. Coming to the end, at least his wives are good for something and they are not vases, I feel that at least he gives them their space to continue in history without being forgotten.

apocalyptic world: average and being very bad until the end, in the first 50-100 chapters I felt that the protagonist was in a crisis and how the world is screwed, but then the author simply does not develop the environment very well, the scenes are They repeat a lot and there is not that harshness that exists in apocalyptic worlds and there is no progress for humanity either, I feel that everything stagnates and after a moment they advanced, but you do not feel it, everything remains the same even if 1 month or 3 months have passed It's weird, as if everything stops until it's necessary to use it, that's why I say that the author didn't develop the world well and focused more on the protagonist's encounters. At this point, I feel like I'm comparing it to "God and Devil World" which does relate to that feeling that humanity progresses, creates communities or the protagonist reaches places where there is already a stable society with its own rules.

the protagonist: he is a guy who maintains his status as anyone who has crossed into another world and wants to take advantage of everyone, he explains very well why he can feel normal in situations of high tension, in personality at least he is not a hypocrite and simply wants to take advantage of all and use all means. It's fine for me, but as I say sometimes the author just forces things that make it look silly sometimes.

the system: it is very broken, literally in the first 100 chapters, maybe a little more a little less, I felt that the protagonist survived the world, after that threshold everyone was simply ants before his system, it was too powerful and I did not feel at all At no time was he in danger, the author gave you excuses, but I simply didn't believe it, at least that forced the protagonist to use his allies and other things, and when he humiliated his rival, he simply crushed him overwhelmingly like an ant while everyone was surprised by his power. Yes, that's how cheeky Chinese authors are, but I was entertained by the machinations that he sometimes did and which turned out to be somewhat ingenious.

antagonists: average, the author shows us points of view and their lives at times, they have good fights and quite strong abilities, but as I said, their only purpose is to be humiliated in a planned way by the protagonist to later be killed in the most overwhelming, and believe me the way he humiliates them is very good and clever.

The ending: it's rubbish, it entertained me, but I was simply reading between the lines to try to finish it quickly because I couldn't stand it, there is no final battle or anything, and even the author himself says that he has nothing more to write, it's a very bad ending. The author increases 16 chapters which are the ones that made my eyes bleed because nothing simply matters and tries to force some things only so that the protagonist ends up being the god and the end.
