That is to say, monks of the Immortal Three Realms are part of the upper-class society in the Shen Hong Realm!
Including Earth Immortals, they are not just some commonplace existence.
Every one of them is numbered, and achieving such status is not that easy.
At least, it's completely incomparable to ancient times when Earth Immortals were as common as stray dogs, or even when Innate Gods would be born at the Saint Realm golden immortal level!
The Saint Third Realm monks of the Sixth Era mostly remain hidden from the world. Of course, there are not insignificant differences among them.
The golden immortals of the Tenth Realm leave traces occasionally, like in the Three Pure Ones and Three Factions, where Profound Immortals might handle daily affairs, but the actual big decisions are still made by golden immortals.
As for the Taiyi of the Eleventh Realm, they are truly saints who have condensed the Taiyi Dao Fruit.
They are already legendary figures in the current Sixth Era.
