Regent, please maintain your aloof image.

Since the start of the school year, Su Qianrou has been going to the academy every day to teach the children.

At this moment, she had just returned to Youlan Courtyard. As she entered the room, she saw Su Jing'an sitting on the couch drinking tea. She was somewhat surprised and asked, "When did Father arrive?"

"It's been a while; you just got back from the academy."

"Hmm," he said, walking over and sitting down, then asked, "Why did Father come? Is there something you need?"

Su Jing'an pointed to the textbook on the table and asked, "Did you write this?"

"right".

"How do you know these things?"

I saw it in a book before.

"What book?"

"I don't remember, I saw it a long time ago."

"Is the book still there?"

"I can't find it. Before I came back, I cleaned out some books, and I guess I threw them away at that time."

Then Su Jing'an asked, "Then why is this book in the hands of the Regent?"

"Regent Prince?" Su Qianrou hadn't expected that Mu Jinchen had betrayed her. She then said, "I don't know. Maybe Princess Chang Le gave it to him."

Princess Chang Le.

"Yes, it was originally meant for Princess Yun Ning. I guess Princess Chang Le gave it to the Regent, or maybe the Regent saw it by chance at the Princess's residence and took it. I'm not too sure."

Su Jing'an had no suspicions and therefore did not think too deeply about it, saying, "Why didn't you tell me? If the Regent hadn't come to me today, I wouldn't have known."

"I was thinking of telling you a while ago, and I even wanted you to help me copy a few books, but you were so busy, leaving early and returning late every day. Then I went to stay at the manor for two days, and when I came back it was Xiao Sen'er's full moon celebration, and then the academy started. Then I forgot about it. Dad, don't be angry, I didn't mean to, I didn't mean to hide it from you," Su Qianrou said coquettishly, holding Su Jing'an's hand.

"I'm not angry. Tell me carefully what these numbers actually mean."

Then, Su Qianrou explained it to him carefully from beginning to end.

From day to night, the two didn't even bother with dinner. It wasn't until midnight, when Chunzhu reminded them, that they had to end their conversation.

Fengtian Hall

The next day, at the morning court session, Su Jing'an stepped forward, cupped his hands, and said, "Your Majesty, I have something to report."

"What brings you here, Lord Su?"

"Your Majesty, I would like to ask you to look at something," he said, taking out the math textbook compiled by Su Qianrou and presenting it with both hands.

Mu Zexuan glanced at Xiao Li.

Little Li understood, and immediately went downstairs to give him the textbook.

Mu Zexuan took it, glanced at it, and asked in confusion, "Lord Su, what is this?"

"Your Majesty, this is a textbook compiled by my daughter. Some of the contents are in foreign numerals, also called Arabic numerals, and some are in simplified characters. Compared with the characters we write now, they are more common and easier to understand, and they are also simple and convenient to write. If used for bookkeeping, they can not only save time, but also reduce manpower and resources."

“It does seem much more convenient this way, what do you think, Uncle?” he said, handing the item in his hand to Mu Jinchen.

"I have already seen it, why don't I show it to you gentlemen?"

"Little Li, take this and show it to the esteemed officials."

"Yes," Little Li replied, then took it downstairs and handed it to Prince Qing.

After reading it, Prince Qing said nothing and gave it to Duke Su.

After the ministers had reviewed it, Mu Jinchen asked, "What do you all think?"

Song Mingxian was the first to answer: "These numbers are easy to write and easy to understand. I think they are very good and worth a try."

"I think this is inappropriate. It is clearly putting the cart before the horse. If such numbers are adopted, will anyone still remember our numbers a hundred years from now?"

"What Lord Wang says is quite right. We have our own numbers, why do we need to use others'?"

"That's right, we've been writing it this way for thousands of years, why should we use a foreign language?"

"Lord Xu is right, Lord Su. You actually want to use a foreign script to replace our own script. What are your intentions?"

"Lord Li misunderstood me. I meant to quote, not to replace. Foreign numbers are indeed much simpler than ours and easier to write. Therefore, we should learn from their strengths and make up for our weaknesses, and be inclusive, instead of being narrow-minded and having limited perspectives. What do you gentlemen think?"

“Lord Su is quite right. I think it’s worth a try,” Song Rui said.

Mu Xinchen echoed, "I also think it's worth a try."

"I second that opinion."

"I second that opinion."

"I object."

"I also object."

"Since you gentlemen have different opinions, why don't you come with me to a place?"

The ministers looked at him with suspicion.

Mu Jinchen did not offer any further explanation.

Afterwards, a group of people arrived at Shengming Academy.

Upon entering, you'll see a three-story teaching building, with an open space in front of it containing recreational facilities such as seesaws and swings.

On either side of the open space stood several large characters: on the left, it read, "Knowledge Changes Destiny," and on the right, it read, "Learning Shapes the Future."

Chunzhu was waiting for Su Qianrou at the classroom door. When she saw a group of people come in, and the person in the lead was Mu Jinchen, she immediately stepped forward and said, "This servant greets Your Majesty and the Regent."

"Where is Princess Ping Le?"

"Your Majesty, the young lady is in class."

"Take us there."

"Yes," Chunzhu replied, terrified because she didn't know why they had come. She carefully led them to the classroom where Su Qianrou was. Just as she was about to call out, Mu Jinchen stopped her, so she had to give up.

Then the group stood outside, listening to Su Qianrou give a lecture inside.

"Now that everyone knows these numbers, we will learn the multiplication table next. Please open your textbooks to page seventeen. Let's read it once: one times one equals one, one times two..."

"Get two, one three equals three, one four..."

Soon, the sound of reading aloud could be heard from inside the room.

The reading stopped a quarter of an hour later. Then, Su Qianrou’s voice rang out again, “Alright, now, I will explain it to you. Everyone must listen carefully. One by one equals one, which can also be written as 1x1=1. Multiplication is a shortcut for adding the same numbers together. And everyone, think about it, isn’t one 1 equal to 1?”

"Yes".

"What about the 2?"

"2".

"By the way, and so on..."

The ministers outside the door couldn't help but start thinking as well.

After an unknown amount of time, the bell rang, and Su Qianrou said, "get out of class dismissed."

Upon hearing this, the children were overjoyed and quickly rushed out. When they saw a large crowd standing outside, they were all stunned and stood there dumbfounded.

Seeing them blocking the doorway, Su Qianrou asked, "Why aren't you going out? What are you all doing standing at the door?"

Xiao Tian replied, "Teacher, there are many people outside."

"Who is it?"

"do not know".

Su Qianrou went outside out of curiosity.
