This means that the time line of a Great Luo Golden Immortal is independent, completely belonging to themselves, and can be modified and altered at will.
Of course, no matter how they modify it, they cannot affect the time line of the Prehistoric World.
If the time of the Prehistoric World is likened to a great river, then the life of a Great Luo Golden Immortal is a mere drop within it.
At the moment they become a Great Luo Golden Immortal, it signifies that this drop of water has been separated by themselves from this great river of the Prehistoric World.
Since it has been separated, its future development naturally has no relation to the Prehistoric World.
The momentum of the Prehistoric World continues forward, but the life of a Great Luo Golden Immortal has already fallen out of this story. The script of their life is no longer written by the Heavenly Dao but by themselves.
