The Yuan Shen's third form was the prerequisite to advance into the level of Atman Body. The opening of the five Yuan Shen realms, and the acquisition of the Combat Yuan Shen formed the foundation on which a Qi Practitioner could advance into the level of Atman Body; however, in order to venture a step higher, not only would that cultivator have to coalesce his mortal body and the Yuan Shen into one, he would also need to open the third form of his Yuan Shen.
The third form was the strongest form of the Combat Yuan Shen. Taking Zhong Yue's Great Sun Golden Crow Yuan Shen as an example, the first form was a scorching sun, the Great Sun; the second form was the three-taloned Golden Crow, while the third and last form was a three-legged winged celestial being — the Golden Crow Celestial.
Zhong Yue had already opened both the first and second form when he was still in the level of Rebirth, but he had yet to open the final and strongest third form.
