"Because the current Bitter Sea System, as well as the vast majority of living beings in the world, cannot digest this kind of energy."
Chen Changsheng calmly gave his answer, then continued.
"Before the Bitter Sea System emerged, the vast majority of cultivators in the Cultivation World used Spirit Stones to cultivate."
"That was because the cultivation system of that era could not digest the pure energy within Divine Sources."
"If they forcefully absorbed it, Divine Sources would be no different from poison to them."
"So back then, Divine Sources were only suitable for sealing certain items and serving as a niche trade currency among high-level cultivators."
"Later, the Bitter Sea System came into being. The cultivation method of achieving Primordial Unity of Essence, Qi, and Spirit improved cultivators' physical bodies and all their other attributes."
"That powerful foundation gave Bitter Sea cultivators the capital to directly absorb Divine Sources."
"And that was precisely why Divine Sources gradually replaced Spirit Stones and became the universal cultivation resource of the Cultivation World."
After hearing this answer, Xiao Hei frowned and said, "Even we can't refine this energy?"
"No!"
Chen Changsheng shook his head. "This energy is extremely special. It isn't simply a matter of the difference between Spirit Stones and Divine Sources."
"For a specific example, take some of the poisonous substances among the Natural Treasures."
"Some special Natural Treasures contain deadly poison within themselves. To use such Natural Treasures, one must master a specific method of refining them."
"If one doesn't know that method, then such Natural Treasures are no different from poison."
"Can you understand what I mean?"
Hearing this, Xiao Hei suddenly understood. "So you mean that only by using a special method to neutralize this energy can the World Spiritual Energy of the Chang Sheng Epoch return?"
