do you know their level of powers? I'm not sure that the book had much info of the difference in levels
besides Immortals , Demi God and God , afterwhich anyone who achieve God hood ascends into God Realm.
In other cultivation novels usually it's Foundation, then Golden Core then Nascent Soul then God etc
TLI seems to establish A yin at Foundation and Gu Jin at Junior Immortal .
Is Feng Yuan/Feng Ran a god already but just on duty at Immortal Realm before she returns to God Realm??
at the end when Hua Shu was Demi God, her powers were only 1/100 000 of Xuan Yi Demon God.
