In Golden Sky World, the skills, cultivation arts, secret skills, secret techniques, and cultivation techniques were divided into four ranks.
Mortal, Earth, Sky, and Sky Breaker, and each rank had two grades; Lower and Upper.
Lower Mortal Grade can be cultivated by First Realm (Gate Realm) cultivators or higher, while Upper Mortal Grade can be cultivated by Second Realm (Foundation Building Realm) cultivators or higher.
Similarly, Lower Earth Grade was suitable for the Third Realm (River Realm) and Upper Earth Grade was for the Fourth Realm (River Core Realm).
Lower and Upper-Grade Sky ranks were suitable for the Fifth Realm (Soul Realm) and Sixth Realm (Manifestation Realm), respectively.
As for the Seventh Realm and fabled Eighth Realm, only the Sky Breaker skills of Lower and Upper Grade can draw out their true potential.
