The delivery boy "Chen Yu" picked up a baby wrapped in Yun brocade on a rainy night, with a piece of black jade engraved with the word "night" stuffed in his arms. The girl would blink her eyes and call him "Daddy". She would drop golden peas when she cried, and tiny white fluff would float up when she smiled. He named her "Nian Nian", but found that the baby could understand cat language, and the potted plants she touched instantly turned into spiritual plants. Even the blind fortune teller in the alley trembled and called her "Little Fairy Lord". One day while delivering orders during a live broadcast, Niannian was shouting "Brother" into the screen of her mobile phone. A man wearing gold-rimmed glasses suddenly appeared outside the camera - it was "Lu Chenyuan", a technology tycoon with a market value of hundreds of billions. The man knelt down and touched the crescent moon birthmark behind Nian Nian's ear with trembling fingertips: "I have been looking for you for three hundred years, my little highness." When Chen Yu looked at the DNA report handed over by Lu Chenyuan, he was shocked to realize that the milk dumpling he had raised for half a year was actually an ancient mythical beast cub that fell into the world during the war between immortals and demons. And this cheap daddy also had a mysterious life experience that even he didn't know.
