The Way of Martial Arts, the Seventh Realm of Spirit Path, Transforming Sea from Spiritual Power, Primordial Golden Pill Realm, Yin-Yang Void Realm and Divine Transcendence!
In the Yin-Yang Void Realm, there would be a change from the original Primordial Golden Pill Realm to a Nascent Soul. The Nascent Soul would then absorb spiritual power, the core of a warrior.
The way that Heavenly Creation Skill reached the Yin-Yang Void Realm was to changed from Gold Core to Nascent Soul. There were not one but two Nascent Souls.
One of them dominated the self and the other reconstructed the body, making up the Yin-Yang doppelganger.
This was the Yin and Yang Breaking.
Jian Wushuang already forged his Yin-Yang doppelganger.
Not only the body and appearance, but the Cultivation of Spiritual Power was exactly like him. The only difference was their thoughts.
