"Fellow Daoist, you may not know, since Yin Thunder Bead is refined in large quantities, artifact refiners prioritize using cost-effective materials for purification.
This is a very normal procedure, although the efficiency is not high, it is relatively economical.
However, from my tests, using Transforming Essence Divine Mud and Tier Three Spirit Washing Sand as the main materials results in high purification efficiency, but the rate of spiritual materials consumption is much lower than expected."
Wan Jinrong raised his brow with pride:
"Even if others have tried this method, without our Wan Clan's secret purification recipe, it's all in vain."
Ten Thousand Treasures Pavilion has subtly become the cultivation realm's finest artifact refiner gathering place in Central Continent, owning many secret technique recipes unknown to the outside world.
"If not mistaken, our Wan Clan's ancestor must have participated in the research of the Yin Thunder Bead, perhaps even as the leader."
