It's actually a Fourth-Order Demon Core!
At the exchange meeting, Zhou Chun looked at the fiery-red demon core inside the jade box with a surprised expression.
A Fourth-Order Demon Core is a treasure and extremely difficult to obtain.
Generally, even if a Fourth Order Magical Beast is unable to defeat a cultivator, it knows to flee.
Even if it cannot escape, they usually choose to self-destruct their demon core, preventing human cultivators from obtaining their most precious possession.
Thus, Third Order Demon Cores can occasionally be seen in the cultivation world, but Fourth-Order Demon Cores are extremely rare.
Furthermore, Fourth-Order Demon Cores have a much wider application range than Third Order ones, whether as a main ingredient for rare spiritual pills, for refining dharma treasures, or for cultivating Fourth Order Magical Beasts, they are greatly useful.
Even cultivators at the Nascent Soul Stage wouldn't mind exchanging for such treasures.
