Kirin Child spoke very politely and carefully explained the origins of the Yin-Yang Realm.
Immortal Lord Miaoyi, Sun Hongyu, and the others finally understood after hearing Kirin Child's explanation.
They understood the significance of the Yin-Yang Realm, as well as the tremendous benefits cultivation within it would bring them.
Since Great Emperor Fengdu had brought them to this hidden place, and such powerful energy was contained within this region,
they were naturally delighted. One after another, they sat cross-legged and began refining the Innate Spiritual Energy.
Within the Yin-Yang Realm, surging Yin-Yang Qi constantly flowed, accompanied from time to time by the sounds of wind breaking through the air.
Within those sounds were strands upon strands of Innate Spiritual Energy.
However, these strands of Innate Spiritual Energy differed somewhat from those Li Changsheng had brought from Kunlun Mountain.
This Innate Spiritual Energy came from the point where the Human Realm, the Heavenly Dao, and the Earthly Dao merged.
This Spiritual Energy carried a trace of Yin Energy. Ordinary immortals could not refine it at all during cultivation.
It was only of some use to ghost immortals of the underworld.
However, none of them paid much attention to it. Things had already reached this point, and cultivating in peace was what mattered most.
After making all the arrangements, Great Emperor Fengdu turned into a ray of light and left the place.
He did not have time to cultivate here, though he too wished to devour and refine this Innate Spiritual Energy within the Yin-Yang Realm.
Li Changsheng's matters were not yet finished, and there were still many affairs within the underworld involving the Ten Halls of Hell and Black and White Impermanence that required his attention.
He could only leave the Yin-Yang Realm for the time being and return to Fengdu
