The Spirit Core is the hallmark of a Golden Level powerhouse and the source of Golden Level power.
For three thousand years, the Alliance has made many attempts on the path to the Golden Level, also pioneering several unique Golden paths for humanity.
For example, the Twelve Golden Bloodlines, where every generation births a Golden powerhouse, is because the Golden Bloodline has explored a Golden path corresponding to its own genes.
The Golden Bloodline emphasizes pure blood. This is not only because of external power and wealth but also due to internal genetic needs.
Therefore, the Golden Bloodline only marries within Golden Bloodlines.
In addition, the Alliance has dozens of paths leading to Gold. The compatibility is relatively high.
But due to differences in personal genes, intelligence, etc., these paths are not suitable for everyone.
According to the Alliance's official statistics, the success rate for advancing to Gold is 13%. This figure is not high.
