Ten Thousand Insect Valley was located in the Hundred Thousand Mountains in the depths of the Southern Wilderness. As the name suggested, there were thousands of poisonous insects wreaking havoc here. It was basically impossible for ordinary people to enter.
Even peak Xiantian experts would have a slim chance of survival if they wanted to enter the depths of Ten Thousand Insect Valley. One could imagine how dangerous this place was.
Only true immortal cultivators could enter and leave freely, but even if they could enter the depths of Ten Thousand Insect Valley, they wouldn't be able to find Hundred Poisons Sect.
Hundred Poisons Sect was located in the layers of formations deep inside Ten Thousand Insect Valley. Or rather, Ten Thousand Insect Valley was the natural barrier of Hundred Poisons Sect, preventing ordinary people from entering. Only immortal cultivators could approach Hundred Poisons Sect.
