In the troubled times of the Republic of China, wars broke out everywhere. Qin Qing, a graduate student in the Department of Modern History, accidentally traveled through time and became the daughter of the wealthy Qin family in Shanghai. However, his family was in crisis due to the possession of a secret map of Japanese military weapons. With the power of "square inches of space", she was recruited by the patriotic organization as the spy agent "Nightingale". She disguised herself as a gentle socialite in the shadow of swords and dealt with various forces.
In order to protect his family, Qin Qing was forced to accept a political marriage with Lu Zhengnian, the king of the north. This iron-blooded marshal is cold and suspicious, and he draws a clear line at first sight, but little does he know that the "peaceful and loving wife" in his eyes is wearing red makeup as her armor, using the marshal's mansion as a camp, using space to convey military intelligence, and secretly protecting her family and country.
Testing in the deep house, exchanging intelligence, she decided the outcome with a single shot at the birthday banquet, and saved him from danger several times in the dark night; he went from being vigilant and scrutinizing to feeling at the top of his heart, shielding her from the wind and rain in the flames of war, and even accepting her secrets and abilities. When love grows in the smoke of espionage wars, the two transform from political allies into life-or-death partners. They work together to smash the Japanese army's conspiracy, eliminate the traitors and the traitors, and protect the family and the country in troubled times.
Hongzhuang goes to danger, and the beacon fire goes hand in hand. Where the nightingale flaps its wings, she finally sees a spark of fire starting a prairie fire.
