Because there were too many, the Time Administration Bureau assigned numbers to these Earths for distinction.
But regardless of the numbering, the development of these Earths is quite similar.
From the era of ancient mythology, to the feudal dynasties of antiquity, then to the modern technological development, and finally stepping into the interstellar future.
However, due to the influences of time, space, and other factors, the development speeds of the major Earths are not the same.
But, the only thing General Tie Yuan can be sure of is—
Earth is a Technology World, even though some supernatural events occur, and some geniuses with special abilities exist, it is entirely different from the Spirit Cultivation World.
In a Technology World, technology is supreme.
In the Spirit Cultivation World, one can achieve immortality.
