I wonder, judging even by the number of gods in the pantheons: Nordic and Egyptian, and comparing it with the number of indicated elements, it should be assumed that there are many more primogenitors and elements than humanity knows. Maybe their territories are much more remote from the Milky Way, and maybe some are still alive and hiding or sleeping. Plus, I don't quite remember the Origin Realm explanation anymore, how is the transition from 6th replacement to this level of cultivation going? And can Felix have more than 6 relpacement, i.e. blood from more primogenitors? And where are humanity Origin level cultivators?
