Mu Wan'er had been wandering around the various realms all these years.
Herbs, be they natural treasures or ordinary herbs, had their own characteristics!
After observing other alchemists refining pills, every alchemist would have their own alchemy method and would even have a unique understanding of the Dao of alchemy.
Even though Mu Wan'er's alchemy skills far exceeded these alchemists, she had learned these methods and insights and integrated them into her own understanding of alchemy.
These elements made Mu Wan'er's alchemy skills rise rapidly!
She had also created many pill formulas!
It could be said that even the pills that Lu Changsheng created weren't as many as Mu Wan'er's.
However, this was also because Lu Changsheng was lazy…
Mu Wan'er was already able to refine a Heaven Immortal-level medicinal pill even with her current alchemy realm!
