The Sacred Nether World is the homeworld of the Ghost Immortals; they are majority in this world. Almost all powerful lineages of the Sacred Nether World were created by experts from the Ghost Immortal Race.
Even so, there are still quite a few powerful lineages of other races, including:
- Simple Mountain Immortal Kingdom, founded by Charming Spirit, Immortal Emperor Di Yu. Their next Immortal Emperor was Fan Chen from the Human Race. The Kingdom's disciples are mainly Charming Spirits, Humans and Demons.
- Thousand Carp River, founded by Demon, Immortal Emperor Qian Li. Its disciples are mainly Demons and Humans.
- Jadewater Country - the main lineage of the Charming Spirit Race.
- Nightwalker Sect of the Blood Race.
- Sky-Devil Gate of the Heavenly Devil Race.
- The Stone Golems also live in the Sacred Nether World, but none of their lineage was mentioned so far.
Other races mainly live in the Distant Cloud region. Demons and Humans are especially powerful here, as the two Imperial Lineages of the region are the Simple Mountain Immortal Kingdom and the Thousand Carp River, consisting mainly from Demons and Humans. Other races like Blood, Heavenly Devils and Stone Golems are a pressured minority even in the Distant Cloud and their lineages are in alliance to support one another.
