The following cultivation stages are drawn from the novel True Heir of Chaos: From Villainess to Empress, which I'm currently translating. I find its system to be one of the most complete and detailed, providing a clear framework for understanding the levels of ascension in the Middle Worlds.
1. Earth Immortal (地仙, Dìxiān)
2. Heaven Immortal (天仙, Tiānxiān)
3. Golden Immortal (金仙, Jīnxiān)
4. Great Golden Luo Immortal (大罗金仙, Dàluó Jīnxiān)
5. Nine Heavens Mystic Immortal (九天玄仙, Jiǔtiān Xuánxiān)
6. Luo Heaven Superior Immortal (罗天上仙, Luótiān Shàngxiān)
7. Immortal Lord / Immortal Monarch (仙君, Xiānjūn)
8. Immortal King (仙王, Xiānwáng)
9. Immortal Emperor (仙帝, Xiāndì)
The pinnacle of the Immortal Plane, Immortal Emperors are nearly invincible among immortals. Immortal Emperors are supreme beings who command the highest authority among immortals.
They wield supreme control over multiple laws and have vast authority. Their presence can alter the flow of celestial bodies, and they are often worshipped as gods by lesser beings.
