Su Wanqing, the daughter of a businessman, was proficient in arithmetic but was forced by her stepmother to marry a domestically violent gambler. In order to survive on the run, she relied on her superb accounting skills to sign a contract with the powerful "Iron Rooster" war king Ye Xuanting who was heavily in debt. She pays his debts and he provides her with shelter.
At first, he saw her as a calculating tool for making money, and she saw him as a ruthless haven. However, amidst repeated business battles, house fights, and court intrigues, Su Wanqing used modern business thinking (such as chain operations, hunger marketing, and branding) to build a huge business empire for Ye Xuanting. She counterattacked step by step from a small accounting office and became a "living god of wealth" that even the emperor was afraid of. Ye Xuanting was also fighting side by side, and was attracted by her tenacity and talent. From a cold and domineering creditor, he gradually became a "wife-protecting maniac" who loved his wife as much as her life.
In the end, Su Wanqing not only completely got rid of the shadow of her original family and the scumbag, but also assisted Ye Xuanting to quell the civil strife and ascend to the throne as a business queen. Together, they created an era of unprecedented prosperity in business and national power.
