In the eleventh year of Dasheng, Shen Yanqiu, the eldest son of Prince Ning, was ordered to return to the capital. She guarded the northern border when she was young. She was restrained, taciturn and cold. She was the most elusive clan member in the eyes of the people of Chang'an. No one knew that the famous Prince Ning was actually a woman. In order to preserve the title of Prince Ning and the military power in the north, Shen Yanqiu disguised herself as a man since she was a child and grew up as a man. She returned to Chang'an, but waited for a marriage proposal from the emperor. She was given a marriage to Xie Linchuan, the daughter of Yushi Zhongcheng. The two were supposed to be strangers in a political marriage, but after their marriage, they discovered that they were investigating the same old case. The military power in the north ten years ago, the secrets of Prince Ning's Mansion, the power struggle in the court, and the past events deep in the imperial city that no one dared to mention are gradually coming to light.
The long night remains unclear, the mountains and rivers are uncertain...
Intention: Marriage first, love later?
