Lu Ba was still in despair, but Lin Feng was deep in thought.
He also learned that cultivators on the Hallowed Beast Continent had a great need for Chaotic prime crystals. It was a circulating currency. More than that, it was a type of energy crystal that assisted cultivation in itself.
For example, if he had enough Chaotic prime crystals, Lin Feng could even condense a second Chaotic Hole. Compared to refining Chaotic dire beasts, it merely could not increase the universe origin, but could allow cultivating the Chaotic Hole.
Empyrean City required Chaotic prime crystals in every aspect, including cultivation techniques, Chaotic martial arts, Chaotic spells, and Chaotic artifacts. They were also used for rent, and people even used them for hiring some Chaotic Perfected Persons to protect themselves on expeditions, and so on.
The Chaotic prime crystals were the universal currency of the Hallowed Beast Continent.
