Outside the Universe

What kind of world exists outside the universe, what kind of creatures live there, and what kind of stories happen? I don't know, I want to see, I want to think about it... (A collection of short stories, used to store the stories I occasionally know when I connect with the outside world) Outside the universe, there may be Witch Stars, Death Stars, Demonic Tide Stars, Tianyi Stars, Xi Stars, Natural Stars, Wind Wheel Stars... Concept: Beyond the universe, infinite possibilities
