In the 15th year of the Republic of China, the situation in Shanghai was turbulent. Shen Qingnuan, the female general of the Shen family who had a large number of troops, unexpectedly learned that her pampered sister for many years was actually an imposter. She found her real sister Shen Qingyue who had been wronged, used thunderous means to rectify the family, and was determined to protect her with all her strength. A baby-swapping incident in the past involved the grudges of two generations, and also concealed a terrifying conspiracy to dismantle the Shen family army and covet the overall interests of the family and the country. In troubled times, Shen Qingnuan avenged his sister with iron blood. The two sisters relied on each other and worked together to create a legend in the turbulent situation. Adapted from the Tomato novel "In the Name of Sister" written by Lin Xiaqi.
