My little world in the palm of my hand

You have a small portable space.

In the outside world, there are violent storms, icy rivers, and zombies everywhere. You can rest, play, and eat hot pot in it.

In the outside world, there are mysterious situations, intrigues, and bullets. You can hide in it and shoot coldly.

When others are short of food and clothing, you have already gathered talents from all over the world to open a factory in your portable space.

What's more amazing is that this small space will expand exponentially as you travel from one world to another, seizing the origin of all worlds, and finally becoming a real world.
