Players from the Starry Sky

Is magic possible in the world? A very childish question with a definite answer: yes. By modifying the code, you can modify the rules of a game, which is magic; by modifying the code, you can also modify the rules of a virtual world, and for the humans there, that is magic. A world can only achieve magic in its sub-world (virtual world). This is an unchanging principle. So, do the many supernatural phenomena in the past prove that our world is a sub-world... Or is it the price of realizing "magic"?
