Ancient Treasure Realms were an extremely rare type of Strange World, nurtured within Chaos. Their traces were seldom discovered, and every appearance caused a tremendous stir.
Each of these strange worlds was vast and self-contained, home to countless spiritual beings and even things that had existed before the creation of heaven and earth. That was why they attracted all the great powers. The origins of such treasure realms were no secret; major figures all knew of them.
These spaces could originally have become worlds of their own, but after the main world was opened, they were forcibly compressed and could no longer expand. Furthermore, when a great war broke out in ancient times, these Chaos treasure realms were caught up in it and their Origin was damaged, leaving them permanently frozen.
The growth of these rare treasure realms had ended in ancient times, which was why they were called Ancient Treasure Realms. It was speculated that during that battle, all such spaces had been affected and ceased growing and expanding.
Such treasure realms contained marks from before the creation of heaven and earth, and even Chaos treasures. Once opened, they would surely offer heaven-defying fortunes and opportunities.
For special reasons, such treasure realms were not easily discovered. This Ancient Treasure Realm in the Lower Realm was connected to the Primal Gate. It had been found by the last Supreme of the Supreme Hall, who had wanted to use it to break into the Immortal Domain, only to meet a tragic end.
After finding the Supreme Hall, Yan Kuan had traced its past and finally determined the location of the Ancient Treasure Realm, though he had left it alone until now. A great battle had just ended, and the barrier between the Upper Realm and Lower Realm could not temporarily reconnect.
