Ancient God Parasitism: Reverse Pollution, I Am a Natural Disaster

They said that it was a miracle that the probability of me being parasitized by the ancient ferocious beast "Yai Can" was one in a billion. But I just feel that I have become a time bomb wearing human skin. This city is full of this kind of "pollution", and I am the most special one. Rather than wait for it to eat me up, or watch the world turn into a living hell—— It's better to let the "pollution" in my body parasitize stronger "pollution"! As long as I am the most vicious one, I will make the rules.
