The universe has a main realm and countless subsidiary realms.
These subsidiary realms are worlds imagined by people in the main realm, also known as the Myriad Worlds.
The movies, novels, animations, and comics of the main realm are all subsidiary realms, worlds that depend on the main realm to exist.
Once the main realm perishes, the subsidiary realms will disappear with it.
But at some point, the subsidiary realms began to warp. These distortions keep growing without limit, eventually causing the realms to vanish one by one. More importantly, once all the subsidiary realms are gone, the main world will be reshuffled.
After the reshuffling, there may be a world ruled by dinosaurs, by *, by cats, by animals, or by plants. There may never again be a world ruled by humans.
At that point, someone will have to repair the distortions in the subsidiary realms.
But the System I've got is such a pain. What should I do?
All the System does is search for knowledge to incorporate into the world, or act as a recorder!
Help, urgently! Anyone there?
After entering a subsidiary realm, I have no magic power and no weapons at all...
