There were few people and many poisonous creatures.
This was the Southern Wasteland.
Along the way, Zhu Wuwan encountered very few cities and the like. There were not even many villages and towns. There were lush forests and shrubs everywhere, and there were often poisonous insects and poisons running amok.
Because of this special environment, the Southern Wasteland was also known as the Poison Barren Land and the Desolate Gu Land. The Poison Gu Art was famous all over the world and was known as a dangerous place in Dongyuan Continent.
Therefore, even if there were some super immortal sects in other regions that were stronger than the super immortal sects in Southern Wasteland, they would not easily invade. Whether it was poison or venomous spells, the super immortal sects here were enough to make the super immortal sects in other territories extremely afraid.
