Prehistoric Universe: The main world was formed from the explosion of Taichu, and has successively experienced three major eras: [Chaos Era] (the rule of the devil), [Open Heaven Tribulation] (the fall of Pangu), and [Immortals and Gods Struggle for Hegemony] (Hongjun Hedao).
Three Thousand Great Worlds: Secondary universes (such as the Mechanical Realm and the Blood Sea Realm) that depend on the prehistoric existence and are transformed from the corpse of the Chaos Demon God.
Terroir characteristics:
The monks use spiritual stones as currency, and the top auctions use divine sources to settle the transactions.
Major holy places use Feixian Arena to resolve disputes, and the loser must donate a hundred years of resources. Mortal dynasties pay tribute to the Immortal Cultivation Sect every year with boys and girls (those with hidden spiritual roots)
Goldfinger:
