It's just not cost-effective.
The resources and Gray Mist needed to make a mortal become a True Master by consuming a Golden Core are enough to let dozens of talented people take this step within ten years.
However, for the beings of Interstellar Civilization, this still has a deadly attraction.
In a purely technological world, life cannot exist eternally.
Even those beings who have digitized their thinking patterns, are the same.
Data will also age!
Unless, you periodically delete excess data, allowing thoughts and memories to return to their original state.
But that would actually be a form of death, not true immortality.
And now, the path to immortality is right in front of you!
Even though the interstellar world Shen Yu emphasized that this is just theoretical immortality, which practically still has mental crises that can affect the body, these civilizations are still drawn to it.
