Shen Jinghong, as the only female commander of the Zhenguo General Mansion, is in charge of the defense of hundreds of people, but she is always laughed at by the noble ladies in the capital as "not as good as a rough man". By chance, the husband she married, Lu Shiyan, was a shopkeeper who was busy doing business. Everyone said that her husband and wife were "a martial artist and a philistine" and were not worthy of joining the powerful. But unexpectedly, mysterious cases broke out one after another in Beijing - theft of tributes, corruption of officials, and the murder of noble ladies, all of which involved the court. Shen Jinghong used force to investigate the case and pursue the murderer, while Lu Shiyan secretly used the business network to search for clues and cut off the money. The noble daughter who used to laugh at her was revealed by her on the spot as a conspiracy; the powerful man who made things difficult for her had his business chain cut off by Lu Shiyan and knelt down to beg for mercy. Shen Jinghong wields his sword to protect his family and country, while Lu Shiyan takes charge of the business affairs. The couple joins forces to solve the mystery while slapping people in the face, stirring up trouble in the capital: "Who said that female generals can't be in charge? Who said that businessmen don't deserve to hold their heads high?"
