The Heavenly Pills, even of the same kind, are divided into various grades.
For example, the Heavenly Pills concocted during the contest with Lord Qingfeng were merely introductory low-grade Heavenly Pills.
Even if one is not a Heavenly Gu Master or Heavenly Alchemist, with a certain level of Alchemy Dao cultivation, it is still possible to successfully concoct them.
The true Heavenly Pills require the invocation of the Power of Nine Heavens, the power of four seasons, and Law Divine Patterns to be successfully refined.
The true Heavenly Pills cannot be refined without a Heavenly Monarch, cannot be accomplished without a Heavenly Furnace, and cannot be completed without a Heavenly Master.
Such Heavenly Pills, once they are out of the furnace, are akin to a Heavenly God descending to earth, their formidable presence will not be much weaker than ordinary Heavenly Monarchs.
