The heroine Jiang Ruyi was originally an unfavored concubine in the Shangshu Mansion, but she had a "koi fate". Anyone who was friendly to her would rise to prominence, and anyone who harmed her would be plagued with misfortune. In order to protect her biological daughter, her aunt designed Jiang Ruyi to marry the disabled eldest son of the Marquis who was about to die soon. Jiang Ruyi relied on her superb accounting and financial management skills and the luck of "doing what she says" to tear apart the hypocritical elders in the intrigues of the Hou family. She first regained the power of the housekeeper by auditing the accounts, and then resolved various scheming schemes between her mother-in-law, daughter-in-law, and sisters-in-law. When her husband's family was in trouble, she single-handedly turned the tide and trampled all the best relatives who had bullied her under her feet. At the same time, the rumored husband who was paralyzed in bed turned out to be a top strategist who had been lurking for many years and strategizing. The two of them joined forces and fought their way from internal fighting in the house to the top of the court.
