The classification of the Abyssal Civilization's levels is quite straightforward, with the foremost requirement being the existence of powerful figures at the corresponding level.
This is the most difficult aspect. For instance, an eighth-level civilization requires the presence of a God, a ninth-level civilization requires a Primary God, and a tenth-level civilization necessitates the stationing of a Divine King.
As long as a powerful figure emerges, other aspects become much simpler, and the civilization will enter a period of rapid development.
As for how many tenth-level civilizations exist in this world, even Meng Xuanshu is unsure.
The Abyss is too vast, hiding many secrets, and civilizations do not trust each other, often erupting into wars, like a dark forest where no one knows how many powerful civilizations are hidden in this boundless Abyss.
