"Incredible, the Tianyuan Realm was discovered by a disciple of the Great Immortal Embracing the Void?"
Seeing the four characters "Embracing the Void Immortal Venerable", An Jing could confirm that they were definitely referring to "Great Immortal Embracing the Void", as that was the Great Immortal's official title.
And the Tianyuan Realm pioneer referred to as 'my master' is clearly one of the twelve disciples previously known to An Jing on the side of Embracing the Void.
Although the Great Immortal Embracing the Void never took apprentices, in the Huai Xu Realm there were twelve nominal disciples with great destinies, five of whom became masters of the Dao Courtyard. The founder of the Shangxuan Sect was one of them, and their lineage has continued to this day, still sitting as the supreme sacred land of succession in the Central Continent.
