Every sub-world must have its own administrator—for example, this particular sub-world has A Lai Ye with the designation 003.
Since there are designations, the other sub-worlds naturally also have their own A Lai Ye with different numbers.
Each sub-world's management bureau is diligently nurturing its own incubator, waiting for it to evolve to the required level—in order to cultivate the most perfect world, different sub-worlds will undergo many restarts and reboots, trying various evolutionary paths.
For their independence, naturally, there are barriers between different sub-worlds that are hard to cross.
However, within the vast system, there are subsystems, and it's impossible for them to be flawless without loopholes—for example, there are beings whose individual abilities surpass the limits set by the sub-world... like the Transcendents or similar entities.
