Every Martial Art Realm was more powerful than before and to get a higher Realm of Martial Arts, a person must absorb Yang Energy, and the more Yang Energy a person absorbs the more powerful they become, and their realm raise.
Martial Art Emperor was the highest Realm of Martial Art a Martial Artist could reach and the power of Martial Art Emperor was enough to destroy mountains.
However, after reaching a Martial Art Emperor, Martial Artist couldn't advance any further, if Martial Artist want to get even stronger then they must learn to control Spiritual Energy and that was Spiritual Artist.
