Fang Mu had an unexpected look on his face when he heard Shui Miao's words.
Fang Mu really never thought that even top-tier pollutants could be contracted by Beast Masters.
He also understood the specific circumstances of the pollution entities from Shui Miao.
The classification of pollution entities introduced by Shui Miao was not mentioned in the books that Fang Mu read.
The books that Fang Mu read mainly discussed the harm of pollution entities.
But now it seems that pollution entities have not only disadvantages but also significant benefits.
Especially for himself.
When Beast Masters contract with pollution entities using spiritual power, the pollution entities will in turn contaminate the spiritual power of the Beast Master, affecting their feelings.
But if Fang Mu contracts with pollutants, like contracting guardian beasts, he only needs to consume Covenant Blood Essence, and there is no need to use spiritual power.
