Legend has it that in the distant Ancient Era, there was an Evil God in the Southern Region. Endowed with vast divine skills and malicious energy, it led countless Evil Demons to incite endless bloodshed in the Mortal Realm.
In times of such suffering, the Immortal Realm, which was still connected to the Mortal Realm then, intervened. A colossal mountain descended from the heavens to kill the Evil God and save the innocent lives of the populace.
The mountain was incomparably vast, needed to suppress the Evil God from the Southern Region and all its evil minions beneath it. Thereafter, this mountain range came to be known as the "Zhennan Region's Mountain". Because countless Evil Demons were buried here, strange events frequently occurred in the Zhennan Region's Mountain, creating innumerable forbidden areas, dangerous regions, and evil-infested lands.
