In Tianjin in 1938, Shen Qingci, the legitimate daughter of a family that carried salt and water, was reborn with a blood feud that resulted in the destruction of her family and her death in Haihe River. Faced with the collusion plan between her stepmother, concubine, ex-fiancé and the Japanese army, she decisively broke up the engagement, eliminated the traitors, and regained control of the family by relying on her legitimate daughter's inheritance rights. Relying on the extraterritoriality and commercial capital of the Tianjin Concession, she teamed up with Gu Yanchen, the boss of the British Concession, the Haihe Gang, and the Song Girl Intelligence Network, and worked step by step in the fields of water transportation and salt affairs. She used "patriotic cloth" to break the blockade of domestic products and used black market channels to transport anti-Japanese supplies. Under the oppression of the Japanese army and the puppet regime, she outsmarted traitors, escorted water transportation, integrated Chinese business forces, and built a solid family foundation in troubled times. She and Gu Yanchen went from an alliance of interests to a life-and-death dependence. In the end, Shen Qingci not only avenged the blood of his previous life, but also protected his family business and helped fight against Japan. He became a legend in the Tianjin business community and achieved the dual perfection of family, country and love.
