In order to break through the earth realm, Morana needed to have all her abilities on the peak of the Mortal Realm, currently, she only had her space and knowledge affinities on the peak of the Mortal Realm but this wasn't the only problem.
Mortal Realm is the only one that can be practiced without any manuals, of course, there is always a difference when one cultivates with one, like her seer abilities.
The only affinity she doesn't need to practice for is her space ability as this ability came from her blood she practically has it in her blood.
All she needs is to have an imagination and high enough magic cultivation.
Magical cultivation before the sky realm only has the job to develop one's body and mana capacity. But after the practitioner breaks through the sky realm everything changes.
