In this chapter, we learn that the scorpion dragon's stomach contains a little world that is part of the "god sea realm." This little world is the owner of each of the 128 worlds in the "tower of sins" , but it's also the home of the little world in the stomach. It's called the "little world" because there's no way to leave it. The only way to get out of it is to use your physical strength, which is what yun-luo just did to meng-chong. This is a common martial art, and it uses the "momentum" of one opponent to break the other's arm in a single motion. This, of course, is the only way out of this little world.
