It should be known that some mid-grade medicinal herbs could not grow in large clusters like low-grade medicinal herbs.
If there were too many medicinal herbs in one place, they would compete for the nutrients around them.
It was like a tree—if it bore too much fruit, those fruits might all end up lacking nutrients.
That was why many farmers picked some of the fruit after it formed.
The remaining fruit could then receive enough nutrients and grow large and sweet.
Medicinal herbs were the same. If too many grew in the same patch of land, the end result would only be that none of them could survive.
Of course, this mainly applied to medicinal herbs with powerful medicinal potency.
Low-grade medicinal herbs only needed a little nourishment.
Yet there were actually so many poisonous herbs here.
This showed that the poison within this forest was already terrifyingly potent.
Otherwise, it could never have nurtured so many poisonous herbs.
Aside from normal nutrients, poisonous herbs could also grow as long as there were sufficient toxins.
Ordinary medicinal herbs still found it difficult to grow amid such dense poisonous miasma.
Thus, the Poisonous Fog Forest was basically filled with all kinds of poisonous herbs.
Xiao Yang did not hesitate and called Xiao Yi Xian over to gather these poisonous herbs with him.
Although these poisonous herbs were only mid-grade medicinal herbs, they could still serve as supplementary ingredients for certain high-grade poisons.
Moreover, they were not bad even if eaten directly.
Or Xiao Yang could simply refine their essence for consumption.
As long as the dosage was large enough, they would still be helpful to him and Xiao Yi Xian.
Very soon, with the two of them gathering together, Xiao Yang stored all these poisonous herbs inside the Medicinal Field Space.
