Among them, some of the medicinal herbs such as the Chengui fruit had to be peeled with spiritual energy first.
In this process, one had to make sure that the outer shell and the fruit inside were perfectly separated!
The Chengui fruit was a mystical fruit that only grew on cliffs.
The attributes of its outer shell and its flesh were completely different.
If one wanted to refine the Barrier pill, one only needed its outer shell.
On top of that, this wasn't the only ingredient that needed to be processed as such.
Moreover, once the outer shells and the flesh were separated, their medicinal effects would quickly be lost!
Therefore, Jiang Yiming had to simultaneously process several kinds of ingredients and combine them at once at the instant of separation!
"So difficult, huh."
What was even more frightening was that these few herbs were totally different from the ones needed to refine simple healing pills.
