I noticed that some readers hadn't understood the basic setting of this book, so I'll explain it here.
World = planet.
Universe = star zone (as divided by the Star Map).
Outer space = Star Sea.
All star zones are contained within the Star Map, which is equivalent to a grand nautical chart of a multiverse.
The Star Gate randomly opens access to planetary worlds in different star zones of the universe.
But sometimes, newly opened planetary worlds may be located in the same star zone as worlds opened before.
For example, the Zero Magic World, the Nuclear World, and Falmart World.
In theory, as long as one possesses sufficiently advanced technology or extraordinary abilities, it is possible to travel between different star zones.
One could either take a space battleship across star-zone boundaries and traverse the Star Sea, or use overwhelmingly powerful abilities to travel through space.
But that is only in theory. After all, even a single star zone is unimaginably vast.
Without the aid of the Star Gate, most civilizations and powerful beings can only operate within their own star zone.
Therefore, even true gods would find it exceedingly difficult—or rather, exceedingly time-consuming and strenuous—to travel between star zones.
You can think of planets as islands, large or small, and universes as seas, large or small.
It is simply that these seas have clearly defined boundaries.
Just as there is a distinct boundary between the Pacific Ocean and the Atlantic Ocean.
It is precisely the boundaries between star zones that keep certain rules of the universe separate and independent.
But once a Star Gate opens, aside from things with absolute restrictions—
Most rules, powers, abilities, and items begin to become mutually accessible.
Lastly, let's discuss the functions of the Star Map and Star Fate.
