The cultivations families had classifications that outsiders didn't know about. Like in the Alliance Star System, a rank 7 cultivation planet was the peak existence on the surface.
Rank 8 cultivation planets were very rare, so much so that the entire Alliance Star System only had three. As for the most mysterious rank 9 cultivation planet, there was only one in the entire Alliance Star System!
The cultivation families in the Allheaven Star System had similar classifications, but they focused more on history. Only long-lasting cultivation cultivation families could become an eternal existence in the Allheaven Star System.
In the Allheaven Star System, the most common were the cultivation families on the main cultivation planets of the four different domains. There was not much difference in their strength, and three or four cultivation families existed on each planet.
For example, the Tang family and the Zhan family were both at the peak of their planets.
