Li Yan, the Crown Prince of Beijing, is known as the Living King of Hell, cold-blooded and ruthless, and not close to women. No one expected that during a heavy rain, he would pick up a dust-free little girl from the roadside. The little girl is well-behaved and soft. She looks timid to everyone, but she is very clingy. From then on, the Living King of Hell transformed into a full-time nanny. The little girl was picky about food, so he washed his hands to make soup and fed her herself. The little girl was afraid of the dark, so he left behind his billion-dollar contract and went home to put her to sleep. The little girl frowned, making the whole Beijing tremble. Everyone ridiculed: "A wild girl of unknown origin, what does Mr. Li want?" But the old man of the Li family, leaning on a dragon-head crutch, burst into tears with excitement: "Pet them all! Pamper them to death! Whoever dares to let her lose a hair, I will make his whole family disappear from the face of the earth!" Later, everyone gradually realized that something was wrong. Sui Sui smiled, Li's Group's stock price soared, and his rival went bankrupt inexplicably. As Sui Sui cries, rain falls from the sky in a drought-stricken area that has never happened in a century, and the stock market of overseas hostile forces crashes. Some people were horrified to discover that the little girl was actually the legendary daughter of national destiny who was the embodiment of luck! As for the powerful Prince Li, his family's mission was to protect her. Late at night, Li Yan held the little girl who had stirred up the world but was still ignorant in his arms. His voice was hoarse and possessive: "Sui Sui, you belong to me, to the whole country, and to me alone."
