Seeing the towering Spirit Stone before her, Bai Xuan's eyes were as wide as beans, her face filled with shock.
Although they were in the Ancient Dragon Emperor's cave and she had seen many treasures with Chu Fengmian, the sight of this Spirit Stone still astonished her.
This piece of Spirit Stone was nearly the same size as the King-grade Spirit Stone that Chu Fengmian had once acquired.
But the Spiritual Power within it was even more refined by a significant amount.
Imperial-grade Spirit Stone!
The value of a single Imperial-grade Spirit Stone was comparable to five King-grade Spirit Stones of the same size.
One could say that this Imperial-grade Spirit Stone before her eyes was valued at five times more than the King-grade Spirit Stone Chu Fengmian had obtained.
Moreover, an Imperial-grade Spirit Stone was in itself a rarity, priceless on the market; even if one was willing to spend a vast fortune, acquiring even one such stone required luck and chance.
