Lin Yunshu, the eldest daughter of the Hou family, was secretly exchanged by Po Wen on the day she was born and lived in the south of the Yangtze River for fifteen years. After her adoptive mother died of illness, her stepmother forced her to marry an old widower who had killed two of his wives. In desperation, she clutched half of the lotus jade pendant and traveled thousands of miles to Beijing to recognize her relatives.
Her biological mother made her kneel outside the gate of the Hou Mansion for a whole day. Lin Xueyuan, the scumbag girl who pretended to be her, broke the token and called her a liar who clung to the powerful. She knelt until she had a high fever and fainted, but she still failed to knock on the red door.
When she opened her eyes again, the person who saved her was the current prince Xiao Yan. He took off his black cloak and wrapped her around her, and coldly scolded everyone in the Hou Mansion: "If someone dies, it belongs to the Zhenbei Hou Mansion."
From then on, Lin Yunshu would never kneel to anyone again. Using an account book, he revealed a deficit of 50,000 taels in the Hou Mansion and took away the power of the family; based on the records of jade and midwifery, he corrected his legitimate daughter's status in the clan elders' meeting; he saw through the arsenic-poisoned tea and teamed up with Dali Temple to uncover the mastermind behind the scenes. The child-exchange conspiracy was planned by the Anyuan Hou Mansion and her biological aunt who lived in the harem, and Lin Xueyuan had been their knife in the Hou Mansion since she was eight years old.
Xiao Yan always protects her. He mended jade pendants and carved jade hairpins, and broke the ancestral system to welcome her in person at the wedding, clearing all hidden dangers for her. He never talked about love, but everyone in the capital knew that the Lord of Anping County was the prince's favorite person.
After fifteen years of wandering, the legitimate daughter returns. From the orphan girl who knelt outside the door begging for help, to the princess in charge of the Phoenix Seal, she took back everything she owed her, took away from her, and harmed her with interest.
