On the third day after she married into the Marquis of Ning'an, she realized that she was not marrying a century-old nobleman, but an empty shell that was about to collapse. The government is in deficit, the accountant is greedy, and the industry is withered. Her mother-in-law asked her to use the dowry to fill the hole, and the clan members were waiting to see her as a merchant girl. However, she opened the old accounts of the Hou Mansion and said only one sentence: "I will not pay back the money you owe. But I can save this Hou Mansion." Starting from a bad debt, she cleared the accounts, reorganized the business, and took charge of the business, letting everyone know that a merchant woman can also be in charge of a century-old house. But when the Hou Mansion prospered again, she discovered that the so-called decline of the family was just a carefully planned situation. If someone wants to destroy the Hou Mansion, then she will let the world see who is really in charge.
