The cultivators came from different factions; it was impossible for them to make their pill formulas, talismans, and artifact-refining methods public. Pill formulas in particular were important inheritances of every major force.
Every major force possessed pill cultivation inheritances. Even for pills with the same effects, the materials used were not necessarily the same. If pill formulas were leaked, gathering materials would become difficult in the future.

But if one asked for ten-thousand-year spirit herbs to refine pills, it would be hard not to arouse suspicion.

Han Changming understood at once and nodded in agreement.

Before long, Han Changming and the other two arrived at a bluestone
