The Jingyuan Marquis Manor suffers consecutive disasters: the heir fails the imperial examinations, the old madam becomes paralyzed, and the marquis encounters danger. Madam Su Wanqing picks up the two-and-a-half-year-old little lucky star Shen Zhiyi at Xiangguo Temple. Yi-yi is born with the ability to communicate with all things, carries a spiritual gourd and prayer beads, and possesses both good fortune and supernatural powers. She successively resolves the manor's crises, cures everyone's stubborn illnesses, and helps the heir have a breakthrough in his studies. Her reputation as a lucky star spreads, gaining the favor of the royal family, and she also exposes the British Duke Manor's witchcraft framing, bringing their evil deeds to light. Yi-yi further assists in improving military crossbows, bringing prosperity to the entire marquis manor and becoming the little lucky star revered by everyone in the capital.
