In this Memory Crystal Stone, it details which worlds have what kinds of resources.
These worlds are all overlooked small worlds, thrown on the road without anyone even giving them a glance.
For instance, in this Memory Crystal Stone, Dong'Er has marked a world called "Earth Profound Continent."
This "Earth Profound Continent," in terms of world scale, is just a "small world," far from comparing to a "Great World," and the battle power ceiling of this world is merely the Mahayana Stage, pathetically weak.
But beneath the surface of this "Earth Profound Continent" there are actually hidden ten "Primordial Dragon Crystal Spirit Veins"?!
......
The Primordial Dragon Crystal Spirit Vein produces "Primordial Dragon Crystals," which are a top-grade spirit stone, only one grade lower than the Holy Dragon Crystal.
