In order to raise money to save her mother, Lianniang, a young girl from Shu, signed a deed and sold herself to the Pei Mansion, becoming the childbearing tool of the disabled and sinister young master Pei Yan. Five years later, she faked her death and escaped, living her life in Yuanzhou. Pei Yan is sickly and affectionate, and after losing all his power, he digs deep into the ground to capture her. Faced with the crushing power and the oppression of her closest relatives, Lianniang fell into a state of sobriety and suffered from hardships. Finally, she used the evidence of the Pei family's centuries-old crimes as a blade to split the golden cage, gave up her status as a concubine, walked the world alone, and finally became a master of Shu embroidery.
