On the Slode Continent, some powerful races would open their own worlds in the dimensional space to avoid being attacked by humans or directly invaded by other powerful enemies.
For example, the dragon race's Dragon Island Empire, elf's Elf Empire, and the giants' Empire. The Slode Continent was vast and boundless, and many races had created their own small worlds.
These dimensional spaces had already been completely occupied by a certain race and had become a real small world. Having a small world meant that there was a supply of resources for the world.
If one wanted to create a dimensional world, then the strength of the creator would have to at least reach the level of a low-rank god. To be exact, the divine kingdom owned by a god was also a manifestation of the dimensional space.
