Zhao Jiaojiao, the daughter of the richest man in the south of the Yangtze River, went north for love, but she was publicly humiliated by her fiancé Zhang Ruiqi: "How can an old-fashioned woman with bound feet be worthy of love?" On a rainy night, she took off her phoenix crown and harem and knocked on the door of the Northland warlord Huo Zhendong: "Marry me, and I can make your army well-fed."
With a contract, she became the commander's wife. Relying on her business skills and Jiangnan resources, she opened up the lifeline of military supplies for him and made every step in the maneuvering field. When the Zhang family went bankrupt and Zhang Ruiqi knelt on the rainy night to beg for mercy, she leaned against Huo Zhendong and chuckled: "Mr. Zhang, now I should call you... Brother-in-law?"
From an abandoned wife to the most powerful woman in the North, she used rouge as her armor and abacus as her blade. She fought for her own way out in the war-torn times and made the cold warlord learn to be gentle for the first time.
