The Gate of Weird Joy

There is a door here, do you dare to push it open? We live in an ordinary world, and most people think so, but has anyone ever thought that this is not the real world, and may be a hunting ground for unknown things; they are very hungry and greedy, and they want to come to the world from somewhere and turn this beautiful world into hell!
