At the Hua Chao banquet, Qiao Mingxi, the legitimate daughter of the first assistant, amazed Beijing with her painting "Fishing Alone on the Cold River", but she secretly set up an spy and vowed to find out the truth about her brother's injustice.
When they first met, she and Xie Jingyu, a young general who was ordered to investigate the case, argued fiercely over the merits and demerits of the founding officials. Their words were sharp, but they didn't know that the thread of fate had been quietly entangled. From the secret letter of the account book about the loss of salt and iron, to the false testimony of the rice paper that the prince was falsely accused of, she used wisdom as a blade to leverage the chess game monopolized by the family; he used iron and blood as a shield to cut through the undercurrent of fog in the court.
When the chieftains in the southwest rebelled, and Beidi was watching closely, she broke the shackles of "women intervening in politics" and opened up a lifeline of food and grass on the Tea Horse Road; he led the army on an expedition and played a triumphant song to quell the rebellion with the improved Hongtianlei. The court battles, the rivers and lakes help, the poor scholars petition for her, and the loyal and brave generals stand by her side.
From looking at each other across the sky on the city tower, to connecting in front of the women's school, to catching thieves side by side on the wedding day, they are not only close friends who meet opponents, but also partners who share the wind and rain.
Qiao Mingxi: "What I want is not only the innocence of my family, but also the innocence of the Haiyan River."
Xie Jingyu: "I protect not only the mountains and rivers of Daqing, but also your front and back."
This is a love that began with intrigue, and it is also a legend in which a pair of beautiful people work together to reshape the world, and finally make Xiyu shine together and prosper and prosper forever.
