The Tyrant's Darling Fell from the Heavens

[One-on-one romance, both leads are each other’s first and only] A little fairy from Penglai Immortal Island made a huge mess by disrupting the order of the mortal world, and was banished to the human realm. To return to Penglai, she must find the souls from other worlds scattered across different realms and send them back to their own worlds. When she watched with her own eyes as the handsome young man who once wore white and smiled like a flower fell from the clouds, ensnared by the chaos of the age and stained with humiliation and filth that should never have touched him… He still forced a smile and said, “Rong’er, as long as you’re all right, that’s all that matters!” In that instant, the little fairy’s eyes stung. In a flash, blood surged like a waterfall. Forbidden arts were unleashed, the stars shifted, and the world transformed. But her soul was scattered, and she was exiled to the farthest corners of the earth like a wandering ghost. Without her, the young prince, whose life had been full of hardship, was like a lone goose with broken wings… Without her, the sickly, possessive regent was like a madman on the brink of death… Without her, the ruthless, brooding emperor’s very soul wailed in agony… In the end, he crossed mountains of corpses and seas of blood, conquering the Central Plains and razing countless cities, all so that one day he might see her again. He sought immortality and the path to the Dao, hoping to live long enough to see the day she returned.
