Of course, this is only for those with insight.

Some people are afraid they will forget them in a blink of an eye.

However, Xu Jiaojiao's explanation was not very high, and those who sat far were a little nervous.

Just like a eldest prince, move the tables and chairs over?

Is it worth it?

However, seeing the eldest prince's thrilling look there, a few people couldn't sit still, so they also asked their subordinates to carry the table and chairs over.

After a while, I moved to the tables and chairs around Xu Jiaojiao, and there was a whole circle.

Only those who were not moved like Hei Mu Tak Hei Mu Ao were angry and embarrassed.

But there are very few such people.

Xu Jiaojiao ignored them and continued to talk.

"You see, this golden base is softer, so it is easier to carve. Some rock patterns and other things here can be made vividly..."

Someone asked at this time,

"Sir, according to what you said, the greater the density of an object, the tighter it will be, right?"

Xu Jiaojiao looked at the man and found that she looked familiar.

"You are, we've seen it before?"

The man bowed,

"The National Master is very good at memorizing. When the seven kingdoms were compared, he fought on behalf of the empire and lost to Lord Du."

It turns out to be square,

The information given by Manager Tang, the son of the prime minister of the empire, immediately appeared in Xu Jiaojiao's mind.

Those who can sit here will not be ordinary people.

But the prime minister's son can sit here at least to show that his son has high hopes for him.

Xu Jiaojiao has a bad impression of him, so she said:

"It turned out to be you. You are right. The more dense the more it is, the tighter it is."

I said:

"Is the density of iron greater than that of gold?"

Xu Jiaojiao:

“No, the density of iron is smaller.”

Xiang Fangyuan asked in confusion: "Why is this? Iron is harder than gold? According to common sense, gold is denser and tighter, so it should be harder, but why is it softer? Isn't this the opposite?

?”

Xu Jiaojiao smiled,

"Your thinking logic is good, but you don't know one thing, that is, the density of metal has no causal relationship with its hardness. No matter which metal it is, as long as it is high purity, its texture is very soft, including iron,

The same is true.”

One person suddenly said:

"Is it exposed now? As we all know, iron tools are very hard, and all irons are hard!"

Xu Jiaojiao looked at it and Hei Mutiao was stretching her neck and looking at it.

Seeing Xu Jiaojiao looking over, she immediately retreated as if nothing had happened.

Xu Jiaojiao doesn't want to quarrel with such an inexplicable person and lose her share.

But it is still necessary to explain it to others, so he said:

"Iron is harder than gold, it's just because people don't need high-purity iron, so it's enough to refine it almost. But gold is different. People pursue the highest purity, so what we see is generally high-purity gold.

”

It's like a thoughtful thing,

"What the national teacher means is that iron is not pure? Don't we need pure iron?"

Pure iron is of course useful, but with the current technological level, it is naturally useless.

Xu Jiaojiao said:

"Yes. Pure iron is also softer, but soft metal is not sharp enough, not hard enough. Sometimes we even add coke to meet the needs of sharpness and hardness, but if we add too much, it will become brittle again.

This is a question that needs to be measured.”

It's clear that the square and round are

"I heard that your country has made a musket that can cause gunpowder to explode in an iron pipe, but the iron pipe is not broken. This is the reason, right?"

Xu Jiaojiao was shocked,

This guy accidentally got a big knowledge point and it was a big loss!

She smiled and said:

"You are really a person who is interested. I think you can inherit your father's position in the future."

Xiang Fangyuan was actually a little embarrassed and bowed:

"The national teacher has been awarded."

Xu Jiaojiao shook her head,

"I'm not polite. There are so many people here, and only you think of this first. This is your thinking advantage and you are proud."

Kuroki Masaya bowed:

"I really benefited a lot from listening to what the national teacher said today! I am worthy of being the second national teacher in the history of Daxiang Country, and I am a famous scholar!"

Xu Jiaojiao smiled,

"Is Your Highness a reverent to me?"

Heimu said, "Of course not. I still say the same thing, as long as the national teacher is willing to stay in the empire, everything is easy to talk about. Don't rush to refuse. Now you don't want to, what if you change your mind in the future? The empire will always be

Welcome!”

Well,

This highness is really persevering!

Kurokio yelled: "Brother! She is our enemy! How could you promise so?"

Kuromu Ao was displeased and said, "Brother, although you are the eldest brother, you still have to get the consent of your father?"

Kurokima's expression remains unchanged.

"There will never be a mistake in recruiting talents for the empire! The empire is just in need of talents like Xu Guoshi. Although she is a great omen, if she is willing to vote for the empire, can't she reuse it? You Muzhao Muao

Are all the families giving birth to children?

Is it necessary to scold, beating and kill if it is an enemy? Are all your enemies dead? They are just their masters. Besides, the national teacher is no more than ordinary people. She is a real national hero! No matter where she is, she deserves respect from others.

!Her talent is enough to make her have a status beyond ordinary people!”

oops!

Xu Jiaojiao was ashamed to hear it.

This prince is really good at carrying sedan chairs, but unfortunately he wasted a good seedling in the royal family.

However, some people in the crowd nodded slightly, which made her feel a little more accomplished.

After Kurokima finished speaking, he ignored them and looked around.

By this time, many people had moved the tables and chairs here, all around Xu Jiaojiao.

The last position before has become the center of all seats!

Kuroki Masa smiled,

"This is the center of discussion on Taoism! There was a saying in ancient times that I learned from the wise and learned from all the people, but now Master Xu is like this, and there are also similar techniques!"

Xu Jiaojiao also discovered it.

There were already the most people around her, and she couldn't help but feel a little proud.

Wherever I am, the center is the center!

I want to keep a low profile, but it doesn't allow strength...

"This is everyone seeking knowledge as hungry, humble and stupid! I am just, well, the stupid bird flies first, and I just take one more step than others." Xu Jiaojiao said.

"The national teacher is too modest!"

Kuroki Masa sighed and looked at the Grand Marshal, "Marrior, let's get to this place?"

The Grand Marshal nodded.

So Kuroki Shin said:

"Everyone! It's almost noon now. Please step into the hall to have a meal, don't refuse!"

After saying that, a nearby servant had already stepped forward to guide everyone.

Kurokima stood up, walked around the table, and walked forward two steps.

"Master Xu, Lord Du, you are important guests today, please be sure to enjoy the glory!"

Alas, you're welcome. If you have food, why don't you?

"Then I'll bother you!"
Chapter completed!
