From Teng County's explanation, Zou Feng began to understand the situation.
In fact, it wasn't just Silk Cave. Other places within Cloud Mist Mountain, such as the Valley of Ten Thousand Snakes and Hundred-legged Ridge, also had their own "forbidden grounds."
These locations had become forbidden grounds because of their unique environments, which periodically gave birth to special poisonous creatures.
It was precisely because these forbidden grounds in Cloud Mist Mountain constantly produced special poisonous creatures that a steady stream of experts in Poison Skills could be cultivated.
Since humans are not naturally poisonous, Martial Artists like Poison Cultivators must rely on various poisonous creatures and substances to cultivate their Poison Skills.
In a way, these forbidden grounds were one of the very foundations of Biyou Palace.
