"Since you haven't been home yet, I came to check on you." Yin Yichen put his arm around Song Wanning's shoulders, his eyes fixed on Tang Heng, and he asked calmly, "Who is this?"

Seeing this, Song Wanning immediately stepped forward and introduced him, "He's a famous zither player in the capital, named Tang Heng. I had the honor of playing a duet with him in the palace today, and we just met again at the city gate."

"So that's how it is." Yin Yichen spoke thoughtfully, then slowly said, "If Master Tang Qin is free, he can visit the Prime Minister's residence."

Tang Heng was stunned for a moment, and it took him a long while to recover. Looking at Yin Yichen, he quickly responded, "Thank you very much, Prime Minister."

Yin Yichen put his arm around Song Wanning's shoulder, and they both got into the carriage of the Prime Minister's Mansion.

Outside, Tang Heng watched the slowly departing carriage, his eyes cast down, a look of loss on his face. A servant beside Tang Heng hurried forward and said, "Master Luthier, why don't we go back soon? The invitations to you from the capital are piling up like a mountain."

Tang Heng responded, retracted his gaze, and said with regret, "What a pity."

As soon as Song Wanning and Yin Yichen got into the carriage, Song Wanning started talking about her experiences in the palace. She frowned and talked about her feelings when she met Prince An and the Queen Mother. "The Queen Mother is so close to Concubine Xian now, I think she supports Prince An. Concubine Xian is favored, and Prince An is powerful. Now Concubine Xian and the Queen Mother both have complaints about you. I'm afraid you will have a hard time in the previous dynasty."

The struggles among the princes in the court were intensifying, and officials were forming cliques for personal gain. Few officials were unattached to the princes, including the Prime Minister and General Song Jing. The union of the two families, a happy marriage, naturally attracted the attention of the princes in the court.

Song Wanning understood the complexity and volatility of court affairs. As the prime minister, Yin Yichen was bound to face many storms.

Hearing Song Wanning's concern for him, Yin Yichen immediately grasped her hand and chuckled softly, "Don't worry, although the court is busy right now, I can still handle it. Prince An is now very powerful in the former court and is relied upon by the Queen Mother. However, the Crown Prince of the Eastern Palace is still there, and Prince An's high-profile actions will only attract attention. Besides, the other princes are not pushovers either, so I'm afraid they'll have a hard time in the future."

Song Wanning looked at the high-spirited Yin Yichen and smiled faintly, "That's good. I can't help you much in the backyard, and I think the family business should be rectified. When I have time, I will go and see what the situation is."

Yin Yichen looked at Song Wanning and said in a low voice, "I'm sorry for the injustice I've done to you today. I'll get back at you one by one in the future."

"It's just a small grievance that is not worth mentioning. Although I suffered some grievances today, I have also won some reputation among the ladies in the capital. In the past, everyone in the capital was afraid of you but wanted to get close to you. The Yin family discredited the Prime Minister's Mansion. These grudges should be remembered. We can't let them succeed." Song Wanning's face was indifferent, as if she was talking about an ordinary thing.

Seeing Song Wanning like this, Yin Yichen smiled and leaned forward, saying, "Marrying Wanning is the blessing I've cultivated for several lifetimes. I used to be too lazy to take care of the people in the Yin Mansion, and I never paid attention to the rumors outside. Now that you're married, my reputation has improved a lot. Now people outside say that my arrogant personality is because I lost my parents when I was young and my relatives didn't discipline me well, which is why I grew up like this."

"What outsiders say is not wrong." Song Wanning smiled mischievously, "That's the truth."

"Madam, you're right." Yin Yichen was clearly in a good mood. He lifted the curtain and looked outside, just in time to see the carriage of the zither player Tang Heng. Tang Heng sat on the shaft, holding his zither in his hands, looking quite cheerful and elegant.

The smile on Yin Yichen's face faded a bit. He turned around to look at Song Wanning and said in a low voice, "That zither player Tang Heng seems to be quite influential. Madam, it would be better if you had less contact with him in the future."

After hearing what Yin Yichen said, Song Wanning just nodded slowly.

The two of them returned to the Prime Minister's Mansion.

Song Wanning said, looking at Yin Yichen slowly, "The shops at home are in the east of the city, which is an excellent location. I noticed something was wrong with the account book, so I thought I would go and see what was going on in person one of these days."

Yin Yichen's eyes were indifferent after hearing this. He looked at Song Wanning and said slowly, "The shops in the east of the city are all managed by a few elderly people. I used to think they were my father's descendants, so I didn't bother to pay attention to them. This made them even more arrogant. Madam, if you can go and take a look, you can ask them to be more restrained, or even replace them. I have been very patient with them now, but I am busy with my work and family affairs, so I don't have time to pay attention to them."

"Now that the job of the housekeeper in the mansion has fallen into my hands, I must make some thorough rectifications. Otherwise, I don't know how much money would be embezzled by the accountant every year." Song Wanning frowned slightly, obviously very dissatisfied with the accountant's behavior.

Seeing her like this, Yin Yichen only smiled faintly and said, "Madam said she would inspect the shop as soon as she got married. Now that she has done what she should do, it is reasonable for her to tidy up the shop."

Song Wanning stood beside Yin Yichen and whispered quietly, "The family property is what you have worked so hard to save over the years. I will naturally take good care of it for you."

Song Wanning's words were true. From childhood on, Yin Yichen had fought countless battles with Wu Junrou, enduring countless hardships, in order to protect the property left to him by his parents. Although the Prime Minister's Mansion was now wealthy, Song Wanning didn't want Yin Yichen's property to be eaten away by termites from within.

As soon as she returned to the Prime Minister's Mansion, Song Wanning took out the copied account books from the shops in the capital and began to read them. Yin Yichen was beside her, handling official business. The two of them quietly read the books for a long time. Whenever Song Wanning saw something wrong, she would take a pen and write something on the account books.

Song Wanning looked at the account book, at her family's restaurant, which should have been the most profitable, and said in surprise, "This restaurant should have been the most profitable business. I don't know why it has become like this."

Seeing her like this, Yin Yichen immediately spoke slowly, "The manager of this restaurant was originally an old servant by my father's side. When the old servant got old, his son became the manager. That's why it has become like this now."

Song Wanning clutched the account book tightly and said in a deep voice, "I should go and take a look."

Within two days, Song Wanning took the account books and began to inspect all the properties of the Prime Minister's Mansion in the capital, including the restaurants and shops in the city and the fields and orchards outside the city, leaving no one unchecked.
