Spiritual energy of higher "quality" could be converted into more spiritual power or magic power in less time.
It met the needs of certain high-level cultivators and high-level formations.

Although I don't know how Bai Lianhua obtained it, now that it's fallen into my hands, I'll gladly accept it.
After repeatedly confirming that it was a high-grade spirit stone, Liu Yu was overjoyed, then briefly sank into thought.
What exactly happened in that distant ancient era?
How could it have caused the spiritual energy of this world to decline continuously, shaping the next million years?

None of the texts he had read so far contained any records of it. Shaking his head, he set the question aside for now.
Liu Yu held the high-grade fire spirit stone in his palm and admired it for quite some time before putting it into his
