Great Tang’s Unparalleled National Teacher

The other side.

Zhang Feng just talked about the importance of geometry academic course and arithmetic, as well as the calculation skills in it, and then he was’please’ out of the classroom by Cheng Chumo and the others who couldn’t wait.

At this time, there is only one group left in the classroom. Staring at what Zhang Feng had just described, which he had recorded verbatim on scratch paper.

After looking at the last arithmetic problem of calculating the total area of ​​a square object, everyone was silent.

Savour carefully the mystery of arithmetic.

Before, they were only exposed to the simplest multiplication tables, division tables, and simple calculations such as addition and subtraction.

They thought it was a familiarity with the mystery of arithmetic, but at this time, after a class by the dean, they suddenly discovered that it turned out that they didn’t count anything here!

Anywhere except on the mountain, as long as they wear the clothes of White Deer Academy of Classical Learning, it is simply a pass, and almost no need to enter and exit Cháng’ān and major restaurant teahouses. Lined up.

No money even in the teahouse!

So much so that all of them are still a little fluttering.

What is this?

This is a status symbol!

This is the face that Lord Dean earned back!

It is the pride of everyone at White Deer Academy of Classical Learning.

But…

Today’s lesson allowed them to recognize themselves clearly. In fact, they are nothing…

Even now, Old Scholar also looked at the arithmetic problems on the blackboard with a solemn expression, and was addicted to it.

At this time.

On the side of the teaching building.

Cheng Chumo invited Zhang Feng here, chuckled and looked at Zhang Feng, rubbing their hands.

Zhang Feng was so scared that he thought these goods were going to kill people.

Quickly asked: “You guys, can something happen?”

“There is something there is!”

Cheng Chumo repeatedly nodded and said: “Now, this Basically, the waterwheel has been dealt with. However, this waterwheel needs to be replaced with an axis almost every day. This is not right!”

“However, we thought of many ways, even I replaced it with an iron rod, or a steel rod. Although it works, it won’t last a few days…”

“So, you took the opportunity to find me here?” Zhang Feng was a bit contemptuous Asked.

Although Cheng Chumo was a little unhappy, he didn’t dare to provoke Zhang Feng at this time. He could only pinch his nose to recognize it, but Du Gou was unwilling and took a copy. The notes I made, I started to theory with Zhang Feng.

Du Gou is notoriously nagging.

The horrible mouth skills can even make people feel horrible.

At least, Cheng Chumo dare not parry, even Li Chengqian can’t resist.

At this time, Du Gou took the shot, and it was also discussed by several people.

Once Zhang Feng doesn’t say anything, Du Gou will take the shot. At this time, Du Gou and Zhang Feng are arguing.

Several people held back their smiles, smoking cigarettes, and silently calculating time in the heart to see how long Zhang Feng could last.

Sure enough, it takes no time to wait for a meal.

Zhang Feng was finally defeated.

“Thank you, Old Brother, I have taken you to success. This waterwheel is almost okay, but it has a fatal weakness, that is, this transmission…”

p>

Without waiting for Zhang Feng to finish, Du Gou hurriedly asked: “Feng’zi, what is this transmission?”

Wei Shuyu couldn’t help but asked: “Yes. , Feng’zi, you just want to make it clear. You just talk about this and that, who wouldn’t you say? This thing, just let me say, I will say it too! Our time has been spent day and night. For countless hours, I still can’t handle this thing by then, so you just turn your mouth on it and talk about this and that, but you can tell me how to solve it! This will be delivered tomorrow, you let us Brother, what should I do?”

Zhang Feng hearing this, he was angry and funny.

But now he knew that if he laughed, he would be beaten up every minute.

Zhang Feng had to sigh: “Do you still remember the Academic Course that I told you on the night I just moved to the villa area?”

Said, the faces of several people turned red in an instant.

Slowly looking around, he got up.

Everyone dares to face Zhang Feng.

No, Du Gou.

Du Gou frowned and turned over the notebook in his hand, and then said: “Feng’zi, this thing, it seems, there is probably some misunderstanding, I remember it clearly in the beginning, you Just talked about the way of power transmission, and how to make the water power form! This has not mentioned the manufacture of waterwheels at all, right?”

Zhang Feng patted his forehead, looking at Du with some curiosity. Gou, went up and took a look at the little book. Hao Ran discovered that this guy was actually taking notes.

Damn it.

Good man, who the fuck writes a diary?

This stuff, actually writes a diary?

However, it doesn’t matter if he writes a diary at this time. After all, he actually said about this matter.

Zhang Feng pointed to the notebook, and then greeted Cheng Chumo with several people over and said: “Come on, you all come and have a look, I don’t believe it, don’t you remember this stuff?”

“Damn, now I asked you to build this waterwheel, didn’t it make him turn?”

“This can turn, is it a power plant?”

In an instant.

A few people suddenly became cheerful.

Cheng Chumo slapped his forehead with excitement, and roared: “Damn, it turns out that’s the case!”

“It’s no wonder Lao Tzu has ripped this thing up. I haven’t seen it before. It turns out that it’s because of this, damn, punch, fucking, you said at the beginning, this thing… I believe in your evil!”

Everyone At this time, the reaction came over suddenly.

His mother was the youngster who said that the manufacturing theory of this waterwheel is quite complicated, and it is far from a power issue, but a manufacturing process…

I knew it was a scam, damn it, they got it out a long time ago, why did it come to this when Feng’zi watched a joke like that?

A few people looked at Zhang Feng’s speechless look, and then at Zhangsun Chong, who was about to stray away. Everyone was angry, Du Gou blowing his beard and staring, grabbed the notebook and shouted: “Damn, beat him!”

“…”
