Nine Mortal Realms (凡体九境)

Elementary Profound Realm(初玄境)
 Strength, speed and senses above ordinary living beings.

Fourteen year old is the critical period of elementary profound foundation.

The first wave of profound strength in the Profound Veins came from one's vitality; precisely, by slowly pulling one's vitality bit by bit into the Profound Veins, it would slowly transform into a sparse profound energy. Once the Profound Veins were filled to the brim with this sparse profound energy, it would be the first official step into a profound strength of the Elementary Profound Realm.

Practitioners with mediocre talent generally required around half a year for this process. Practitioners with great talent could complete it within three to four months. Once this extremely important foundation was completed, one could then continue to further cultivate by absorbing the vitality from the sky and earth. There was no way around this process because only after officially entering the Elementary Profound Realm, would one have the ability to use their Profound Vein to absorb the vitality of the heavens and earth.
The Only Exception to this is Jaune as A Week After Jaune Reaches 14 He already Perfected His Foundation.
