While the cafeteria was preparing lunch in an orderly manner, the fields were also bustling.

Wearing hats, the villagers stood barefoot in the fields, grasping rice seedlings in their left hands and sickles in their right hands, and cutting rice with their hands and feet.

In the open space are two wooden threshers.

Jiang Yao was wearing a hat, teaching the people around him how to use the thresher in the open space.

"Put a small handful of rice on top of it, and then step on it with your feet to make it rotate, and turn the rice over to make it clean...... "Jiang Yao demonstrated with his hands and feet.

The surrounding villagers stared at the rice grains that had been carried off by the iron teeth, and their mouths were slightly open.

Even Su Yu'an, who was standing on the side, couldn't help but take a few steps forward......

In fact, Su Yu'an was even more surprised than the villagers.

In this era of backward technology, such mechanical objects are rare.

In Su Yu'an's eyes, this kind of thing only exists in some mysterious tricks written in the book.

Although the villagers think it is magical, are there still few magical things on Jiang Yao and Jiang Yu?

It's no wonder if you've seen too much.

Su Yu'an watched Jiang Yao finish threshing a handful of rice in a short time, and his eyes were full of brilliance.

Although they have survived in a low-key manner over the years, there are not many large and small Zhuangzi.

He had also seen rice harvesting in his own village, and he had studied it with great curiosity.

Naturally, I know that whether it is an ordinary farmer or a big family, it is threshed by beating.

Because he knows, he understands the value of such a tool better than anyone else.

Jiang Yao and the others were so defenseless in front of him, how could it not be a kind of trust?

Jiang Yao: Brother, you think too much......

After Jiang Yao taught it once, he stepped aside and let the villagers try it, turned his head and saw Su Yu'an staring at the thresher with a curious face, and said with a smile: "What? Brother Su also wants to try it? ”

To be honest, Su Yu'an thought in his heart.

However, he glanced down at his robes.

Forget it, let's take a look......

Jiang Yao saw his small movements in his eyes, looked down at the washed and faded coarse cloth clothes on his body, and his specially blackened hands: "......"

Su Yu'an pondered for a moment and asked, "Brother Jiang, dare to ask this...... Threshing...... Machine? Can it be passed on? ”

Jiang Yao knew what he meant, and said generously: "Why not?" ”

Su Yu'an was pleasantly surprised, "Really?!" ”

"Nature." Jiang Yao paused and continued: "If you just use it, then you can use it at will." ”

"Of course." Su Yu'an understands that this is not allowed to be used for profit.

Su Yu'an looked at the rice field in front of him and said, "Although I don't do production, just looking at this heavy ear of rice, I know that this yield must be high." "As for how much higher, we will have to wait for the harvest to be weighed.

"If the people of Sanzhou can get this grain and have such a useful tool, it will be much better in the coming year."

Jiang Yao didn't speak, if she could do this, it would naturally be the best, which was also the main reason why she was looking for the Su family to cooperate.

Making money is certainly one thing, but the fact that high-yield grain can be spread to ordinary people through the Su family is also an important factor for her to consider.

The old village chief listened on the sidelines, but he was quite touched, "Don't worry, the climate in Qingzhou is not too cold, go back and send this grain to the past, carefully raise the land and raise seedlings, and the harvest will be bad." ”

That being said, no one knows how much this acre of land can be harvested.

For a while, everyone stopped talking, and watched fixedly as the rice in front of them was harvested little by little, and the grains of rice were taken off......

The land they are on is relatively close to the river, and it is one of the most fertile in the village.

Ten men went down to the field, and with the swing of their sickles, they had cut off an acre of land in half a day.

The two threshers have not stopped, and the threshing process is almost complete when the harvest of one acre of land is completed.

The stripped paddy is packed into sacks and then lifted to the open field to be weighed.

Everyone didn't even bother to drink the tea, so they all gathered around.

Bags of rice were picked up, and the villagers who were waiting there weighed them with scales and shouted loudly about the weight.

There was a table next to the clearing, where Mr. Feng and Chen Ze'an were recording.

"Thirty-two pounds...... Twenty-nine pounds...... Thirty-five pounds ......"

As the weights were reported one by one, the abacus in Mr. Feng's hand moved quickly, and Chen Ze'an was cooperating with the record.

Lin Changsheng, Lin Xiaoxi and the others were all watching from the sidelines.

It's just that Lin Xiaoxi is looking at the data recorded by Chen Ze'an, and Lin Changsheng is looking at the abacus in Mr. Feng's hand, and his fingers are hanging down and moving by his side.

A few days ago, he went to listen to arithmetic classes whenever he had free time, and although his learning was still relatively shallow, he could understand it somewhat.

I thought that he had missed a lot of classes before, and it would be difficult to listen halfway.

But what he didn't expect was that the content of the arithmetic class was not too deep, and he would review it every few days, and slowly, he could barely keep up.

In fact, this is the case in every elective.

It stands to reason that each course should be divided into different levels.

But they don't have that many gentlemen, they don't have so many classrooms, and even the villagers don't come to the lectures at a fixed time.

So there was a period of time when the teaching effect was not good.

Especially in arithmetic, not to mention missing a class, it is a little distracted in class, and then you may not be able to understand.

Later, Jiang Yu and Mr. Feng summed up, anyway, they were not required to be able to take the imperial examination in a short period of time, and it was more important to learn arithmetic to cultivate some people who could manage things as soon as possible.

Then put some esoteric content aside for a while, and then repeatedly understand how to calculate.

For this reason, Jiang Yu even talked to Mr. Feng about some modern mathematical calculations.

But Mr. Feng, as an orthodox pedant, has doubts about many of Jiang Yu's statements.

Keep asking why......

Jiang Yu was able to answer at first, but as Mr. Feng continued to ask, Jiang Yu gradually couldn't resist.

The different periods of the historical process are the huge generation gap between the two.

For example, Jiang Yu couldn't explain to him how the numbers after pi 3.14 were calculated.

You can't just tell him that the computer calculated, right?

Then she has to explain to him what a computer is, so when will it be a head??

Mr. Feng said that arithmetic is a very rigorous thing, and if he can't prove it, he can't accept it.

Jiang Yu was forced to be helpless, so he wrote some calculation questions casually.

Since it doesn't make sense, let's go head-to-head!

Then, when Mr. Feng quickly dialed the abacus to finish a question, Jiang Yu had already written out all the questions......

It's not that Mr. Feng's abacus is not playing well.

In fact, Mr. Feng's calculation speed with an abacus is not slow at all, and if it is put into modern times, it is definitely a master.

However, Jiang Yu cheated.

The calculation questions she wrote were:

25*25

1010101*34

67*63

23125*11
