After Saving the Alien World, Why Did They Come Here?

Congratulations on saving the SSS level difficulty alien world and you are now back. Mission reward: unknown. With the fall of the devil, Jiang Lin was finally able to return to modern society. "I'm still too tired from defeating the Demon King..." It is better to enjoy modern life. Just when Jiang Lin was preparing for a new daily life—— The girls he had met by chance appeared in various rooms in his house inexplicably. Elf, princess, brave companion... Wait—why is the Demon King here too? ! Not bad, Without their permission, they can only be trapped in various rooms. Since none of you want to go back—— Elf? Use this modeled face to give me cosplay gold coins! Princess? You can also be a man in leather bags and blast gold coins for me! Former magician companion? Just use your extremely smart brain to run it for me! Demon King? Become a harmless piece of trash that can only play with your mobile phone! Jiang Lin? Of course, enjoy it all! After being a brave man for so many years, what happened to enjoying yourself? ... Some years later. Jiang Lin looked at the girls gathered in the living room, "Put the knife down first and listen to my explanation——" "Scumbag!" "Didn't I agree that I would be the only one to follow?" "Isn't it enough to have both of us?"
