Four Divine Heavens' Economy

"The Jade Heaven, huh? I will keep that in mind. And speaking of wealth, how different is it in the Divine Heavens compared to this place when it comes to their economy?" Xian Ni asked.

"It's entirely different. While they also have spirit stones and still use them as currencies, it's only worth as much as coins do to mortals in this world in the Four Divine Heavens. In other words, mortals use spirit stones as if they are coins over there whilst spirit stones are worth a fortune to mortals in this world."

"What the heck? Then what do Cultivators use?" Xian Ni asked.

"Spirit stones, but a different kind."

Su Yang then retrieved a spirit stone and showed it to him, "Imagine this tiny spirit stone a little bigger, and it contains enough spiritual energy to make a Cultivator at the Elementary Spirit Realm reach the Heavenly Spirit Realm before running out of spiritual energy."

Xian Ni's jaw dropped. How can such spirit stones possibly exist?
