My Little World in the Palm of My Hand

You have a little pocket space. Outside there are violent storms, glaciers, and waves of zombies. You can rest, play and eat hot pot inside. The outside world is full of secrets, intrigues, and bullets. You can hide inside and make cold shots. When others are short of food and clothing, you have gathered talents from all over the heavens to open a factory in your personal space. What's even more amazing is that as you travel from world to world, this small space seizes the origin of all worlds, expands exponentially, and finally becomes a real world.
