Southern Border was known as the Demonic Land.
The 100 races which ruled over this land were all top great demon races that had survived since the Antiquity Age and had invincible arts.
That was the reason there were so many demon prodigies.
Amongst all the races, the strongest would definitely be the Immortal Phoenix and Kun Peng races.
Both races had powerful Sub-Immortal cultivators presiding over and were extremely strong.
It could be said that the Southern Border demons' battle prowess was not weaker than other regions at all.

Also, the terrain here was perilous, and thus it had a natural cover for defense.
There were thousands of steep mountains and valleys.
Those mountains towered into the clouds and were boundless, looking magnificent.
100,000 mountains surrounded the Immortal Mountain in the center as if they were 100,000 guards protecting their emperor. It was a grand scenery.
