My Pocket World of Immortality

One day, Lu Mi discovered that he had a small world inside his body. He could put various things into it, including land, water flow, humans, spiritual beasts... And even moves. Since then, the immortal cultivators in the small world have never had a peaceful life. What do you mean by flying swords falling from the sky like rain? What does it mean that a large group of spiritual beasts appeared out of thin air? Okay, okay, I don't even act anymore, why do I directly play the demon from outside the realm? In the big world, Lu Mi looked at his stunned opponent and smiled. Still want to fight? I'm not full yet.
