The production of the genetic liquid medicine is indeed limited, but after Huang Chengcheng and Qin Huai'an diluted it, the total amount increased.
He didn't know if the diluted version significantly reduced the effectiveness for Earth cultivators, but as long as it worked for Southern Domain cultivators, he didn't mind diluting it further.
The number of Earth cultivators is not very large, and the genetic liquid medicine is sufficient.
As far as he knew, Earth cultivators actually still had genetic liquid medicine stored. After taking it, they either experienced change or didn't experience any change at all, and thus stored the allocated genetic liquid medicine for future sale to Southern Domain cultivators in exchange for other resources they needed for cultivation.
In that case, this business must be monopolized by his own people to maintain order and prevent Southern Domain cultivators who wanted the genetic liquid medicine from getting it cheaply.
