Shen Jinghong, the legitimate daughter of the Zhenguo General's Mansion, was framed by the eldest princess Zhao Yuyao in her previous life. She was accused of collaborating with the enemy and treason, and the entire Shen family was executed. On the execution ground, she saw Zhao Yuyao on the high platform from a distance, but there was no joy in his eyes, only deathly silence. On the same day, Zhao Yuyao, who had been exploited by her relatives Liu family, was given poisoned wine by Empress Dowager Liu and died in the cold palace with hatred.
Once they opened their eyes, they both went back to ten years ago - Shen Jinghong had just entered Beijing to get married, which was the beginning of the Shen family's injustice case; Zhao Yuyao was still the favored eldest princess of the dynasty, and had not yet become an abandoned son of the Liu family. There was a bloody feud in their previous lives. Both of them wanted to strike first and set up tests again and again, but they were shocked to find that the other party was also a reborn person.
As the investigation deepens, they gradually uncover the truth: the destruction of the Shen family and the death of Zhao Yuyao in the previous life were all a conspiracy of Empress Dowager Liu and Liu's relatives' group, who were in charge of the government. Both of them were just manipulated pawns. Former rivals are forced to put aside their grudges and form a secret alliance.
Zhao Yuyao was in charge of the harem, well versed in people's intrigues, and built an intelligence network for the inner court; Shen Jinghong traveled to the frontiers of the previous dynasty, was proficient in military battles, and took charge of the forces in the army. From the concubines in the harem to the important ministers of the former dynasty, from the local salt tax case to the life-and-death war at the border, he cut off the Liu family's arms step by step, found out the truth about the injustice in the previous life, and finally overthrew the entire concubine group.
At the end, Shen Jinghong was honored as the general of the country and guarded thousands of miles of rivers and mountains; Zhao Yuyao was named the princess of the country and assisted in the Qingming Dynasty. The two stood side by side on the Danbi, completely rewriting the fate of tragic deaths in their previous lives, and building a prosperous and peaceful world together.
