Started out really well but after about chapter 30-40, the MC leaves his world and so it no longer becomes an apocalypse story but closer to a an isekai. Granted, I am only about 80+ chapters into it at this point, but I was expecting something completely different from the description and name of the story. It's not bad and I can see why others would enjoy it, but it no longer holds my interest. I might pick this back up later, but for now I am going to have to drop this novel.
