In the dark era, ten thousand years after the Desolate Heaven Emperor stood alone across the ages, the laws of heaven and earth have collapsed and the world has become a wasteland. The once-glorious Immortal Domain lies shattered, the Myriad Worlds are in chaos, and dark calamities break out again and again. The protagonist, Ye Xuan, awakens amid the ruins with no memories, yet possesses a mysterious power of reincarnation. As he searches for the truth of his origins, he meets Ye Xian, daughter of Ye Fan; Wuming, a descendant of Wu Shi; and Su Yu, an heir to the Ruthless Great Emperor. Together, they set out to uncover the source of the dark calamities. They traverse desolate ruins, unravel the mysteries of ancient relics, and battle powerful dark creatures and hostile forces. Along the way, the remnant soul of the Reincarnation Sparrow within Ye Xuan gradually awakens, revealing his mysterious connection to Shi Hao, the Desolate Heaven Emperor. They also uncover a shocking secret: behind the dark calamities lies an ancient force seeking to overthrow the entire universe, and this force is inextricably linked to the disappearance of the three great rulers.
