From that day on, he diligently practiced Artifact Refining every day.
In half a month, he earned a total of 720 Spirit Stones.
He used 500 of those Spirit Stones to purchase two Yang Fire Stones, successfully upgrading the Huayang Bead to a Middle Grade Spiritual Object. The most noticeable improvement was that he could now take one Purifying Spirit Pill every eight days, reducing the interval by two days.
However, Zhao Zuo learned a piece of common knowledge about Pill Medicine from Xue Liang: every type of pill has a fixed usage limit. For example, after consuming fifty Purifying Spirit Pills, their effect would begin to diminish, and after one hundred pills… they would become completely ineffective.
This news made Zhao Zuo pay even more attention to the Huayang Bead's ability to refine Pill Poison. If it could raise the consumption threshold for Purifying Spirit Pills, his own Cultivation speed would increase dramatically.
