Right after Shui Miao finished advising him, Fang Mu felt a bit awkward asking him such a question.
But he had no other choice, as behind him there was no real Grandmaster Creator.
Aside from Shui Miao, he could not get any answers elsewhere.
Fang Mu had already decided to trade all these pollutants from Shu Liangjun, and then select one of the three special-grade pollutants to form a contract.
So, it was crucial to ask for details first.
Having been in contact with Fang Mu for so long, Shui Miao well knew of his strong curiosity.
He had already given all the necessary advice, and if Fang Mu really wished to form a contract with a pollutant, he would certainly need to report to his master.
In Qixing's capacity, she would surely be able to dissuade Fang Mu.
Therefore, Shui Miao simply told Fang Mu about the cultivation of special-grade pollutants.
"For a special-grade pollutant to advance in grade alone, it just needs to devour other pollutants to gain pollutant energy."
