Meng Clan is on decline but there are so many Dao realm cultivators?
edited February 2017
1st Rate Power - Has a 4 Essences equivalent or stronger and a few more Dao Realms (some foundation is needed, after all)
2nd Rate Power - 1 Dao Realm
3rd rate Power - At least four Ancient Realms
Shit rate Power - Self-explanatory.
Fang Clan is at peak of 2nd rate, Ji Clan is at bottom of 1st rate, at least thats how I see it.
