Shen Qingyan, the only daughter-in-law of Dajing, was famous throughout the world for her majesty as the God of War. However, in order to avoid the Queen Mother's pressure to marry her, she "robbed" Xie Weishi, a poor scholar, on Zhuque Street to become her son-in-law. It was originally a contractual marriage in which each took what he wanted, but it hid a shocking secret - the docile son-in-law was actually Murong Che, the prince of the subjugated Southern Chu Dynasty, who lurked in the prince's mansion just for revenge; and the mysterious lotus seal in Shen Qingyan's hand was related to the blood of the three clans and the seal of the world.
Poisoning at the palace banquet, strange poisons in the West Cross Courtyard, and conspiracy in the Xuan Pavilion came one after another. The hatred of the country and the family were intertwined with the hidden emotions. When Murong Yuan (the leader of the Xuan Pavilion) broke the seal with his residual spirit, the grudges and centuries-old secrets of the three clans surfaced, and the former enemies were forced to stand side by side.
From contract temptation to life-and-death support, from opposing positions to deep-seated love, Shen Qingyan and Murong Che used love as a blade and blood as a shield to finally break the thirty-year deadlock and stabilize the Xuanlian seal. In the end, the phoenix crown was added to the body, and the emperor and the empress got married. They took the country as their betrothal and their life as a promise to safeguard the peace and prosperity of the Dayin country and the people. A misplaced marriage eventually became an eternal legend.
