Zhaowei

Shen Zhaowei, the concubine of the Department of Ordnance, is capable of listening to iron and distinguishing stoves, and is capable of carrying swords and killing people. Three years ago, her father was falsely accused of collaborating with the enemy due to the "Yanmen Iron Case" and was imprisoned. She and her younger sister disguised themselves as men and infiltrated the Ordnance Department, starting as a handyman in the Iron Distribution Department. The "official iron" allocated by the court was being replaced by private iron mixed with sulfur and phosphorus. The soldiers in the frontier army were all holding scrap iron that "collapsed within three months of use." The dandy Prince Ningshuo, Pei Ji, is actually another trapped bird on the same rope as her. He took her under his wing in the name of "concubine", and she continued to investigate the case through his identity. The private kiln fire, the autumn defense banquet, and the three locks of the official treasury—uncovered a major case of collaboration with the enemy that involved the blood debt of 30,000 border troops and pointed directly at the top of the court. The trapped bird in troubled times finally breaks out of its cage.
