I recommend the following novels about the apocalypse and rebirth. The number of chapters meets the requirements: Doomsday God's Space, Doomsday Rebirth: Women, Don't Escape, My Doomsday Fortress, Doomsday Evolver, Doomsday Rebirth, Doomsday Dawn Redemption. I hope you like this fairy's recommendation. Muah ~😗
