Nantian Sacred Land.
It resides within the Nantian Mountain Range to the north of the Southern State, the most famous expanse far and wide.
Legend has it...
In Ancient Times, when the Hall of Longevity unified the Qingtian Realm, Southern State was merely a corner within the dominion of the Hall of Longevity.
To travel from Southern State to the Hall of Longevity for pilgrimage, one had to cross the daunting Nantian Mountain Range.
This path is known as the direct route from Southern State to the heavens.
Hence, it was named the Nantian Mountain Range.
However.
Ever since the Ancient Times when Martial God Zhao Wuji triggered the cataclysmic War of Extinction, which plunged the Hall of Longevity into the depths of the void and caused the Qingtian Realm to fragment, the Nantian Mountain Range, too, split along with a large section of land, eventually forming the present Southern State.
The name Nantian Sacred Land also exists because of the Nantian Mountain Range.
