Shen Jingwan, the legitimate daughter of the Anguo Hou Mansion, was criticized as a "disaster star" because her mother died in childbirth due to a vision coming from the sky when she was born. After she got haircut, the man she was engaged to fell from his horse accidentally and died, and her reputation as "Kefu" became real. She was rejected by her family and lived a life inferior to that of a pig or dog in the Hou Mansion.
In order to seek wealth and honor, the family treated her as trash and married the seventh prince Xiao Zhuyan, who was sick and dying due to poisoning. They wanted to use her "unlucky" to "fight fire with fire" and gain access to the royal family.
Everyone was waiting to see her kill the prince and become a laughing stock. Unexpectedly, after Shen Jingwan married into the palace, he changed from his previous cowardice. He used his secretly learned superb medical skills and meticulous scheming to uncover the ghosts in the palace, and detoxified Xiao Zhuyan from the strange poison, so that his body gradually recovered.
Then, as a princess, she began to take crazy revenge on the people in the Hou family who had bullied her: cutting off her stepmother's wealth, ruining her concubine's marriage, and ruining her sanctimonious father's reputation. Internally, she rectified the palace, eliminated all informants, and managed the palace to a solid level; externally, she relied on her extraordinary business acumen and precise control of people's hearts to accumulate wealth and win over people's hearts for Xiao Zhuyan.
From the initial mutual testing and cooperation, the couple developed trust and deep love for each other. In the turbulent battle for the heir, Shen Jingwan repeatedly made clever plans and became Xiao Zhuyan's strongest helper and most trusted adviser, helping him step by step from a sick and weak prince who no one cared about, to the pinnacle of power, and finally to rule the world. And she also went from being a "disaster" despised by everyone to becoming the most noble woman in the Daye Dynasty, truly realizing a prosperous husband and a prosperous country.
