Daming: Grandpa Emperor, please get up and sit on my throne!

I saw that the other person was so heartless that I complained about him.

Zhu Yunhuan had long been accustomed to this, and he didn't comment on his words. He only said with interest: "Last time, didn't I hear you complaining about the little emperor? How come you changed so quickly? The little girl still has two faces?"

Having said that.

But this was just a joke he made when he was bored.

After all, he also knew that although Xu Miaojin was a little arrogant sometimes, it was only because she came from a military family and was young and hated evil. She would complain when she saw something unjust, but would also praise good things when she saw them.

Xu Miaojin curled her lips.

In her mind, she was clear: "One thing is one thing. Regarding the fabric matter, I respect him as a man! I'd say the same thing if you asked me now. What he did today was so foolish. Even if the king came, I'd say the same thing. I don't know what's going on in his head."

This time she started complaining about Zhu Yunhuan again.

However, Zhao Feng, who was responsible for protecting Zhu Yunhuan and always liked to go against her, rarely said anything. He just stood at the window with his arms folded, staring down.

For nothing else.

Very few people knew about anthracite. In Yingtian Prefecture, only Ma Sanbao and Song Zhong knew the truth. Even those who handled and transported the anthracite did not know what it actually represented, and the same was true for Zhao Feng.

and so.

This time, Zhao Feng really felt that the little girl was right.

Even he didn't want to refute it.

"Your servant is so quiet today. I thought he was going to say I was bold and rebellious again!" Xu Miaojin obviously noticed it too.

Zhao Feng could only turn around and give her a blank look, then quickly explained himself: "Didn't our master ask us to give in to you?"

Doubts in one's heart are psychological doubts, but serving the emperor is like serving a tiger, so one must keep one's butt straight. If one does not speak for Zhu Yunhuan, then there must be a reason for not speaking for him. Fortunately, His Majesty had actually stopped him when he was confronting this little girl before, so there is nothing wrong with what he said.

However, Xu Miaojin seemed to have heard something else.

He just thought that it was because this girl had contradicted him too many times and was criticized by Zhu Yunhuan in private that he didn't dare to respond to her now.

"Humph!"

She lifted her chin and snorted softly.

The little face, which still had a little baby fat, suddenly turned rosy, and she shook her head slightly, revealing a bit of pride that the little girl could not hide.

Then he seemed to remember something.

He looked at Zhu Yunxun with great pride and said, "I finally figured out the problem you gave me last time!"

After saying that, he took out a crumpled piece of paper from his sleeve and spread it out in front of Zhu Yunhuan. On it was written the solution process.

Zhu Yunhuan took a casual look.

He nodded and said, "The distance is correct. You are indeed quite capable." He never said anything against his will, and at his current position, there was no need to say that the compliment was genuine.

A little girl of twelve or thirteen years old.

If converted to the 21st century, they would only be in the first grade of junior high school, or even in the sixth grade of elementary school.

In the process of nine years of compulsory education.

Physics is not learned until the second year of junior high school.

That's it.

There are also countless people who learn to chant Amitabha and complain bitterly.

He just took advantage of the occasional time when he went out of the palace for a private visit to explain more to Xu Miaojin. Newton's three laws of motion, universal gravitation and so on were not difficult to understand, and she could even do the math.

Another point is that people of this era might memorize various classics, history books, and miscellaneous collections, but they didn't deliberately study mathematics! To solve physics problems, you need some basic mathematics, which was taught during this period.

Perhaps it was also because she was born in the Duke of Wei's mansion, and her family would train her in simple mathematics such as accounting as she would be in charge of the family home in the future.

But this is already terrifying.

"Hehe! Of course!" The little girl couldn't hide the truth. When she heard Zhu Yunhuan actually praised her, she couldn't help but feel even more proud...

After a pause, she frowned slightly, a hint of daydreaming on her face, and said, "But...it turns out that Chang'e, Jade Rabbit, and Wu Gang really don't live on the moon. Beyond the Earth are Venus, Jupiter, Mercury, the Moon...all of them revolve around the sun..."

"What's further out there? How big must it be..."

Young girls naturally enjoy imagining things, and as a daughter of the Duke of Wei, Xu Miaojin naturally had a carefree family life. During this time, she felt as if she had been exposed to a whole new world and new rules, which naturally made it easier for her to let her imagination run wild.

It was like I had a hundred thousand questions at the moment.

Zhu Yunhuan did not answer her directly. After all, if he continued to talk about this, it would take more than a short time to explain it clearly.

Instead, he said something meaningful: "It is humankind's infinite thirst for knowledge and exploration that allows us to see ever-broader horizons time and time again."

Xu Miaojin wanted to ask something else.

But then a shrill and high-pitched voice came from outside: "Silence! Eunuch Sanbao is here!!!"

As this voice sounded.

The noisy sounds outside the window suddenly became quiet.

After all, with Ma Sanbao's current status, it is no exaggeration to say that he can walk sideways outside. Even civil and military officials have to respect him when they see him. In addition, everyone already knows that Ma Sanbao is the protagonist today, so his appearance naturally appears unusually solemn.

"The eunuch Sanbao who is beside the little emperor has arrived!" Xu Miaojin swallowed back what she wanted to say for the time being, her eyes lit up slightly, and she said with a hint of curiosity and anticipation on her little face.

After all, she came so early today just to see what the little emperor would do, and she was also very curious.

It was not for any other reason, but she really wanted to know what the little emperor wanted to do by making such a big fuss.

He was clearly a person who was willing to bear many insults for the sake of the people of the world, and was even willing to damage his own foundation to cause turmoil in Yingtian Prefecture, but he was like this today.

"Let's go over and take a look." Xu Miaojin raised an eyebrow at Zhu Yunhuan and invited him.

Zhu Yunhuan nodded.

He was the one who led this matter, so of course he wanted to see the results.

The two of them stood up and walked towards the window one after another, and Zhao Feng, who had been standing by the window, took the initiative to give up his seat.

As soon as I walked to the window.

Xu Miaojin seemed to have discovered something, frowned, and uttered a puzzled sound: "Hmm?"
