On the second floor of the Medicine Hall Collection Pavilion, there were quite a few books on the alchemy insights of various Pharmacists. However, there weren't many books about elixirs like the Three Revolutions Nourishing Viscera Pill, Guiyuan Pill, or Qi Replenishing Pill. These were elixirs that only Intermediate Pharmacists could refine, or perhaps even only Advanced Pharmacists.
Among the ten Intermediate Pharmacists in the Cyan Yuan Sect, not many could refine the First Revolution Nourishing Viscera Pill.
This was because some Intermediate Pharmacists in the Cyan Yuan Sect hadn't been promoted based on their alchemy skills, but rather on their abilities in medicine, judging medicinal properties, and concocting prescriptions. This, in turn, limited their path for further advancement.
