Most regions of the Shading the Heavens World were the Nine Heavens and Ten Lands after the Perfect World era, an End of Dharma World following the Desolate Heaven Emperor's enlightenment.
The Longevity Substance that had once been found everywhere had withered away, leaving even Great Emperors who reached the pinnacle of the human path with only ten thousand years of life. They could only live another lifetime by relying on Immortal Medicine.
