Very few members of the other races live in this world. These races include:
- Ghost Immortals
- Blood Race
- Stone Golems
- Charming Spirits
- Heavenly Devils

The Brilliance Ancient Kingdom with two Immortal Emperors, one from the Stone Golem Race and another from the Heavenly Devil Race, is the nation with the most races; they are even called the Hundred Races Kingdom.
Another Imperial Lineage, the Eternal River School, was also founded by a non-human, a Charming Spirit, Immortal Emperor Xiu Shui. Their other Immortal Emperor, Guan Feng was also not from the Human Race. However, their third Immortal Emperor, Nu Zhan was a human and Humans in general are not in minority there unlike the former two nations.
