The main reason was that he already had a rich reserve of knowledge in alchemy. The Celestial Azure Pill Flame, a fourth-grade unique flame, was particularly suited for refining pills, slightly increasing the success rate and quality of the pills.
The fourth-grade medicinal insect, the Pill Worm, fed on the toxins within the pill furnace and the pills themselves, greatly aiding in the pill-refining process while also benefiting itself. Additionally, there were three types of pill formula experience packages: the Foundation-Nurturing Pill, the Spirit-Nourishing Pill, and the most important, the Foundation Establishment Pill.
From previous light orbs, he had absorbed many pill formula experience packages, especially for the first two, reaching a master level in refining them, confident that he was not inferior to many alchemy masters in the Alchemy Hall.
All these factors led Lu Xuan to decide to try his hand at refining pills.
