Regent, please maintain your aloof image.

When Su Qianrou saw that it was Mu Jinchen and Mu Zexuan, along with many ministers, she was very surprised. After a moment, she bowed and said, "Greetings, Your Majesty and Regent. I was unaware of Your Majesty and Regent's arrival. I apologize for not welcoming you properly. Please forgive me, Your Majesty and Regent."

"Princess Ping Le, there is no need for such formalities."

"Thank you, Your Majesty. May I ask what brings the Regent and other dignitaries here?"

"We heard that Princess Ping Le has compiled a math textbook and is teaching students here. We were curious, so we came to see it and learn something along the way," Mu Jinchen said.

Su Qianrou looked at him and thought to herself, "He's really putting on an act, acting as if he just found out." "Your Highness is joking. You are all well-read, learned, and erudite people. How could I dare to show off in front of you?"

“Princess Ping Le, there’s no need to be modest. We have all benefited greatly from your lecture just now,” Song Rui said.

"The princess's talent truly impresses me," Bai Qinming also said.

Mu Xinchen said, "I knew the princess was wise, but I didn't know she was so intelligent. I admire her."

"You three are too kind."

"Just now I saw that there were girls in here. Why does the princess teach even girls?"

“What are you saying, sir? I am a woman myself, why shouldn’t I teach girls?”

"Women don't need to learn these things; they only need to learn the precepts and virtues for women."

"If we follow your logic, then shouldn't I also be standing here?"

The official was speechless for a moment.

Then, Su Qianrou said, "A teacher is one who imparts knowledge, teaches skills, and resolves doubts. Therefore, in my opinion, students should not be distinguished by social status, gender, or academic performance. Anyone who is of good character is a good student."

"It is truly rare for a princess to have such insightful views at such a young age," said Song Mingxian.

"You flatter me, Lord Song."

At this moment, the bell rang again, and Su Qianrou said, "I still have class, please make yourselves at home." After saying that, she looked at Mu Jinchen and Mu Zexuan and said, "Your Majesty, Regent, I will take my leave now."

"Princess, please go and attend to your business."

Mu Jinchen said, "The princess shouldn't mind if we look around."

“Of course I don’t mind,” she said, then looked at Su Jing’an and said, “Father, please help me entertain His Majesty, the Regent, and all the other officials.”

"it is good".

Su Qianrou then left.

"Your Majesty, Your Highness, may I attend Princess Ping Le's lecture?" Song Rui asked.

"Of course, other adults may also listen if they are interested."

"Thank you, Your Highness."

Then, most of the court officials went to listen to Su Qianrou's lecture, leaving only a small number of people standing in place.

Mu Jinchen looked at them and said calmly, "If you gentlemen are not interested, you may go back first."

"Your Highness, I believe..."

"Lord Li, there's no need to say more. If you have anything to say, you can wait until tomorrow morning court to discuss it."

"Yes, Your Majesty, I shall take my leave now."

"We take our leave."

After saying that, the adults went out.

Then, Su Jing'an asked, "Your Majesty, Your Highness, would you like to go inside and rest for a while?"

“No need, let’s just walk around,” Mu Jinchen said.

"Yes".

Then, the three of them toured the entire school.

On the way back, Su Qianrou and Su Jing'an sat in the carriage.

Su Qianrou asked, "Father, why did His Majesty, the Regent, and all the other officials suddenly go to the academy today?"

"This morning at court, I presented the textbook you wrote to His Majesty, intending to use the Arabic numerals you mentioned for bookkeeping. This caused quite a stir among the officials. Then, the Prince said he would take us somewhere, but unexpectedly, it turned out to be the academy you founded."

"Why didn't you say you were coming earlier? You always launch surprise attacks," Su Qianrou cursed inwardly.

"However, how did Your Highness know that you opened an academy, and even know where it is?"

“You received the umbrella of ten thousand people, even though you were far away in Yangzhou. The prince knew about it, let alone what happened in the capital. How could the prince not know?”

Su Jing'an thought about it and it seemed to make sense, so he didn't think much of it. Then, remembering something, he said, "By the way, I heard that when you went to the manor a few days ago, it was the Prince who accompanied you."

"How did Dad find out?"

"Now everyone in the capital knows this."

Su Qianrou looked incredulous.

"The Shadow Guard is the Prince's personal bodyguard, and he is inseparable from the Prince. Yet, he personally escorted you to the manor that day, which speaks volumes."

"How could I have forgotten about this?" Su Qianrou was filled with regret.

Su Jing'an couldn't help but ask, "Rou'er, you and the Prince...?"

Su Qianrou could tell at a glance that he had misunderstood. "Father, our Prince has important matters to discuss. I asked my uncle to bring back some crop seeds from a foreign land. These crops are not only easy to cultivate, but also have extremely high yields. Therefore, I informed the Prince of this matter. The day I went to the mountain villa was to check on the growth of the crops. When the Prince learned of this, he went with me."

Su Jing'an exclaimed in delight, "You said those crops have extremely high yields!"

"Ok".

"How tall."

"One mu of land can produce fifty to seventy dan."

"really".

"Absolutely true."

"How did you find out? You read it in a book."

"Um...yes."

"Rou'er, are you sure you can achieve such a high yield?"

"No matter how much I say now, it's all empty talk. In two months, when the crops are ripe, Dad will know that what I said is true."

"If that's the case, then the famine can be alleviated."

Mu Jinchen sat at the dragon desk reviewing memorials, while Mu Zexuan read a book beside him. Neither of them spoke, so the hall was very quiet until Su Qianrou entered.

"Your Majesty, I greet you, and I greet the Regent."

"Sister Su, you're finally here!" Mu Zexuan happily ran to her side and took her hand.

Mu Jinchen merely glanced at her indifferently before lowering his head again to continue reviewing memorials.

"I've kept Your Majesty waiting."

"There are no outsiders here, Sister Su, you don't need to be so polite. Just call me Xiao Xuan."

"Okay, Xiao Xuan."

"Sister Su, please explain that math to me, I'm very curious," she said, pulling her to the dragon throne and sitting down. Seeing Su Qianrou standing, she patted the throne and said, "Sister Su, sit down."

Although there were no outsiders here, who knew if someone might come in later? If someone saw her sitting on the dragon throne, she would probably lose several heads. Therefore, she said, "I'd better stand."

Mu Jinchen did not look at them, but instead ordered, "Bring a chair for Princess Ping Le."

A moment later, Xiao Li brought over a chair and placed it behind Su Qianrou.

"Thank you, Father-in-law," Su Qianrou said, then sat down and asked, "Is there anything you don't understand, Xiao Xuan?"

Mu Zexuan pointed to the textbook and said, "I don't quite understand this part."

“This…Doesn’t Your Highness already know?” she said, looking at Mu Jinchen.

Mu Jinchen remained unmoved, as if he hadn't heard her words.

"My uncle said he was too busy and told me to ask you."

Su Qianrou had no choice but to explain it to him.

Looking at the three of them, Yingfeng seemed to see his future prince and princess teaching their young master together, and couldn't help but smile.

Mu Jinchen unconsciously looked at Su Qianrou. Seeing her serious expression, a strange feeling welled up in his heart, though he didn't know what it was, but he was in a very good mood.
