Shen Zhaoning, the daughter of a guilty minister, had her family ruined and became a sin slave in Yeting. Everyone tried to avoid her, but the cold and sickly Ninth Prince Pei Yunche came to her through a pool of blood and stretched out his calloused hand to her: "Follow me and become the Princess of Chu."
On the wedding night, a contract was written, stipulating that everyone would get what they wanted. She used his hand to overturn the family's case, and he used her name to consolidate his power.
Everyone knows that this is a cold transaction that is destined to not end well.
Until he blocked the scalding hot soup for her at the Chongyang Palace Banquet and was scarred; until he knelt in front of the emperor and asked for the title and honor of "Princess Roujia" for her; until they joined hands to peel off the cocoons amidst layers of traps and bloody killings, approaching the truth that could overturn the country...
When the contract becomes a fetter, and the use becomes sincerity, he uses the country as a trap and recruits her into the cage; she uses sincerity as a blade to break the situation and become a phoenix.
"Shen Zhaoning, this country has married you for me, and you will be my wife for all eternity."
