๐I recommend the following novels to you: "Doomsday Supermarket System","Doomsday Omnipotent System","Doomsday: I Activated the Red Alert System","Doomsday Positive Energy System", and "I Am a Doomsday Hunter". These novels were all about the system of the apocalypse. The plot was thrilling and had its own characteristics. It was very interesting. I hope you like this fairy's recommendation. Muah ~๐
