As an outer enforcer of Medicine King Valley, Yao Thirteen possessed an exceptionally peculiar Natal Gu.
Corrosive Poison Gu: a special Gu insect that fed on poison. By consuming various poisons, it could concoct a unique corrosive toxic gas.
The Corrosive Poison Gu alone was not that strange, but its Auxiliary Gu were filled with ingenious ideas.
The Great Appetite Gu, Fermentation Gu, and Detoxification Gu—these three Auxiliary Gu worked directly with the Corrosive Poison Gu to turn Yao Thirteen's body into a super-sized culture medium.
Relying on Medicine King Valley's abundant poison resources, Yao Thirteen had begun consuming all kinds of poisons fifteen years ago.
