Jiang Yi had learned from He Nongying that this world was like a pagoda split into three realms: the Pan Universe Small Realm, Minor Chiliocosm, and Major Chiliocosm. These three realms formed the Primordial World.
The Pan Universe Small Realm was made up of uncountable domains and people; these were the lowest-grade domains where the martial artists residing in them were extremely weak. They were like aborigines to some in the Higher Domain.
There were seven Minor Chiliocosms which each had more than ten thousand domains where formidable martial artists were plentiful. Although the Major Chiliocosm only had ten domains, this was the pinnacle of the pagoda; the number of formidable martial artists here was astounding. Even just some of them could easily destroy a Minor Chiliocosm.
