Lin Qingwan, the legitimate daughter of the Prime Minister's Palace, was born on the night of the Lantern Festival. As soon as she was born, she was maliciously replaced by her cousin Liu Yuru. Her biological daughter occupied the magpie's nest, and she was abandoned in a ruined temple on a barren mountain. Fortunately, she was adopted by a couple in a mountain village. The daughter-in-law's safety button around her neck became her only token of recognition.
Mrs. Lin noticed something strange after giving birth. Although the Lin family saw through the fake safety button, there was no evidence. For sixteen years, the secret investigation was obstructed by Liu Yuru. The fake daughter-in-law enjoyed all the honors and favors despite her status, and made a marriage contract with the legitimate son of the general's mansion.
Lin Qingwan rescued the reclusive master Zhuge Mingxuan in a mountain village and learned martial arts and martial arts. Her master also found out her life experience. When she was sixteen years old, she took the safety buckle and embarked on a journey to find her relatives. On the way, she met Xiao Jingyuan, the incognito prince, and the two went together to find evidence.
With the safety buckle and irrefutable evidence, Lin Qingwan went through difficulties and setbacks, proved her identity with her intelligence, and finally won the favor of the Prime Minister's family. Her relationship with the prince gradually blossomed and became fruitful. Her adoptive parents took her to the capital to enjoy their old age, her master was awarded the title of Imperial Master, and her three brothers also found a good match. A secret exchange conspiracy that lasted for sixteen years finally ended successfully with the return of her legitimate daughter.
