Primordial Universe: The main world was formed by the Primordial Beginning Explosion. It has passed through three major eras: the [Chaos Era] (ruled by the Demon Gods), the [World-Creation Calamity] (Pangu fell), and the [War for Supremacy Between Immortals and Gods] (Hongjun joined with the Heavenly Dao).
Three Thousand Great Worlds: Secondary universes dependent on the Primordial World, such as the Mechanical Realm and the Blood Sea Realm, formed from the remains of Chaos Demon Gods.
Local Customs and Conditions:
Cultivators use spirit stones as currency, while top-tier auctions settle accounts in divine source.
The major sacred grounds settle disputes on Flying Immortal Arenas, with the losers required to surrender a hundred years' worth of resources. Every year, mortal dynasties pay tribute to the immortal sects in the form of boys and girls, some of whom secretly possess spiritual roots.
