As the daughter of the Marquis of Xuande, Yaya is cast out to a country estate with her mother, who is despised for having seduced her way into a man's bed, and left to fend for themselves. Hated by her scoundrel father and looked down upon by her maternal uncle, Yaya suffers abuse at the hands of her half-sister. Just as she is on the verge of death, the Myriad Worlds Child-Raising System activates, and powerful figures from every realm shower her with love. Yaya befriends the Imperial Consort, the Grand Princess, the Crown Prince, and others. Using her special system, she brings good fortune to those around her. Meanwhile, Lady Lin holds a grudge against Yaya and schemes relentlessly to kill her. She even places a curse on Yaya's mother, seeking to deny her peace even in death. When Yaya discovers that her mother's death was suspicious, she resolves to travel to the capital and clear her mother's name.
