Shen Qing, the eldest princess of Yan Wenyuan, entered into a royal marriage contract with Lu Yunzheng, the general of the country, since she was a child. In the eyes of outsiders, the two have always been indifferent to each other. No one would have thought that there was a different kind of deep love hidden behind this seemingly peaceful fate. When Lu Yunzheng returned from the expedition, he was accompanied by a woman named Qian Ning, which caused people all over the city to speculate. By chance, Shen Qing was able to hear Lu Yunzheng's inner voice, and was shocked to realize that this general, who acted decisively and uprightly in the outside world, was thinking about her frequently and caring about her in private. Just as the plan of Nanzhao Prince Yuan Huai gradually surfaced, the turmoil between the court and the border gradually arose.
