It's a different manwha (That's kinda rare), the scenario and worldbuilding is creative, you gotta give that. To me, the main problem is the generic trope of the hero who can overcome it all, idk if it's me who's cynical but I dislike it, even more that it's thrown in your face so many times.
I think time will fuck this manga, but I liked the creativity. 8.2 for now
