The pill recipe and medicinal ingredients for the Evergreen Pill were all provided by the Green Bull Demon King. After so many years, Yang Zhenshan had already researched the pill recipe to utter thoroughness, yet this was still his first time refining the Evergreen Pill.
Even though his Alchemy now stood at the very peak of the Wanhua Domain, he still remained extremely cautious about refining the Evergreen Pill.
There was no helping it!
The medicinal ingredients required to refine the Evergreen Pill were simply too precious. Among them, there were over thirty kinds of Third-stage Spiritual Medicine, and more than four hundred kinds of Second-grade medicinal materials.
If he ruined several furnaces in a row, even that filthy rich Green Bull Demon King would probably be unable to bear it.
