South Emperor was born in the same generation as Hong Tian during the Emperors Era. He is extremely talented, to the point that he is among the top ten geniuses across the ages. At fifteen he was already powerful enough to became an Immortal Emperor, but was defeated by Hong Tian and decided to seal himself to evade one era. He came out at twenty, only to met Bing Yu and be defeated once more. He sealed himself again and came out at thirty, but was again defeated, this time by Qian Li. Having no choice, South Emperor hid again.
Later, he decided to put aside his ego and seek advice from Li Qiye as the Sacred Teacher of Immortal Emperors. Li Qiye gives him 2 options. One of them is to evade this generation and become a Immortal Emperor in next generation, and the second is to live dazzlingly and chose the path of Immortal Monarch.
He becomes a 4 Heaven's Will Immortal Monarch in the Tenth World with the potential to gain 12, by drawing 4 Primal Wills (the first Heaven's Will formed in an era) which is purer than the normal one and makes obtaining subsequent Wills easier.
