"Uncle Liu thinks that compared with ordinary fields, how much more grain can be harvested from this 'kind field'?"

Listening to the worries of the two old men, Liu Wei was not in a hurry to explain, but asked rhetorically.

The old man surnamed Liu was obviously more thoughtful, and the disappointment on his face flashed away, but he thought about it for a while, and replied seriously:

"In recent years, the weather in my hometown has not been good, but we old planers have done it ourselves, and we have more than two coarse grains per acre, more than 200 catties. If this is the land...... I'm afraid it's 400 pounds. ”

As soon as his words fell, Lao Wang on the other side had already interjected impatiently:

"At least five hundred! If you can't beat it, you will cut off my old king's head! But what's the use, it's not enough for a few men to eat......"

Speaking of the back, the voice became lower and lower, and even the head that had been held high was much lowered.

The old crop style can't make people eat enough, and it also makes a village of people leave their hometowns and live abroad, and the old man is obviously angry about this matter and has become a heart disease.

Liu Wei is the most respectful and responsible person, and bowed his hand to the two, and then continued to ask questions.

"In this case, if the fertile land in the world can produce 400 ...... per acre No, three hundred pounds of grain, so what? ”

The two old men were stunned when they heard this, and then laughed.

"The little doll thinks it's a beautiful thing, why are we worried? Where are so many 'auspicious' in this world, how can anyone afford to serve the good seeds of a seedling in this acre of land? If there are really so many good seedlings, you can harvest two or three hundred catties while lying down, how can there be such a good thing! ”

After Liu Laohan finished speaking, he was afraid that Liu Wei would not understand and added.

"I know, you mean to keep the seeds...... But the matter of keeping millet for planting is different from harvesting land, and the grain seed can not be set aside for three or four hundred catties. Even if we old guys tended to these two acres of land together, we wouldn't be able to leave a few acres of good seeds. We are all old, and we still have a few years to live, so what's the use of getting those dozens of acres of good land? ”

When Liu Wei heard this, he also smiled.

He finally found the crux of the problem.

Liu Wei looked around, and finally saw a stack of wooden shelves in the corner of the courtyard, his eyes lit up, and he took three or two steps over to get one.

Acupoint plate, also known as seedling tray.

Small lattices enclosed by wooden frames on a wooden chassis can be used to grow seedlings after being filled with soil.

This stuff is a great lab aid.

Liu Wei put the seedling tray on the ground, took the fried rice used to serve the tea on the side, put one in the first grid, and put two in the second grid.

"Uncles, guess how much grain of grain would it take to fill this plate if I put four grains of rice in the third grid, and then put twice the amount of the previous grid in each grid?"

The story of the preschool education level in the previous life was asked by everyone present.

"That's how many."

Lao Wang snorted coldly, but snatched the small plate in Liu Wei's hand and began to fill the lattice with fried rice one by one.

Liu Laohan thought about it sideways, and seemed to feel that something was wrong, but he took a small stick and wrote and drew on the ground on the side.

He is literate, otherwise he would not have been able to take advantage of the limelight to get the appointment of the imperial court.

Seeing that the two of them were busy with their own work, Liu Wei turned his head sideways to look at Tang Ying, who had been silent and listened quietly except for pouring water for a few people.

The Tang family's little sister's good-looking eyebrows wrinkled into a small bulge.

The face was faintly flushed because he was too focused.

Obviously, I was calculating the answer in my heart, but I encountered some bottleneck.

In just a few breaths, Liu Wei saw that his daughter-in-law seemed to have calculated something, looked at it with a shocked face, and then nodded and motioned for her to wait for a while.

On the other side, Lao Wang had already exhausted the fried rice in his hand, and as a result, he didn't even fill the first row of eight grids.

And Liu Laohan's side has obviously encountered the threshold of computing power, and he is stuck in the second line, so he can't count it anymore.

Liu Wei didn't expect him to be able to calculate clearly, and it was already excellent to be able to count.

He just stretched out his hand to signal, and Liu Laohan handed over the wooden stick in his hand with a confused expression.

"You don't need to be precise about calculating this."

Liu Wei said, clicking on the eleventh grid.

"Uncle Liu counts so far, how many are there?"

"One thousand and twenty-four." Liu Laohan was full of energy, obviously quite confident in his arithmetic ability.

"That's right." Liu Wei said, writing a 1024 on the ground.

Then, erase the last two digits and fill in the two zeros.

"We don't need precise numbers, we just need to know the approximate amounts."

This number is strangely written, but Tang Ying's eyes immediately lit up.

Liu Laohan frowned and looked at it for a long time, and nodded slowly, as if he understood something.

Liu Wei smiled and handed the wooden stick back to Liu Laohan.

After a few calculations, everyone's faces were dumbfounded.

I don't know how many, but the long string of zeros on the ground speaks volumes.

You don't need to say it too clearly, you can just stop it when you click it.

Of course, the actual operation of seedling cultivation is not so simple.

But just a small game of arithmetic is enough to inject them with a shot in the arm.

After holding their breath for a long time, the two old men exhaled a deep breath, and the whole person seemed to be a few years younger.

This is a good thing, and Liu Wei is very satisfied with the effect.

As for the little sister of the Tang family......

What man wouldn't like his daughter-in-law looking at him adoringly?

But......

I laughed at my "revenge" for being an errand in the palace before, and I still have to take revenge.

Under the little black background of the Liu family, a nameless ghost never dies!

……

The matter came to an end, and Mr. and Mrs. Liu got up to say goodbye.

The two old men were still immersed in the shock just now, but they didn't forget the etiquette, and they got up to send each other off.

As a result, before they reached the door, they saw the three of them stepping into the courtyard.

The first three wisps of ink hair looked heroic, and the man's face was full of solemnity, and he bowed deeply to this side.

The two behind him also clasped their fists and saluted, looking very serious.

Liu Wei naturally knew the person who came, but it was not good to say it in front of the two old men, so he returned the salute and went out of the courtyard with the visitor.

The convoy set off again, but in the direction of Yanshi.

Liu Wei did not get on the car this time, but rode on the back of a beautiful little red horse without a trace of miscellaneous hair, and walked side by side with Cao Cao.

"Liu Gongzi's remarks today are really eye-opening."

Cao Cao has always been cautious, and before the team entered the city, he was careful to call him.

Now that he has entered Yanshi City, he naturally can't speak at will.

But seeing him like that, he still said it after enduring all the way.

"Don't hide it from the son, when the son ordered Cao to Tuntian, he was still a little depressed in his heart, and he thought that he was overkill. Looking at it now, Gongzi is a gift to Cao in the name of a hundred generations, which is contemptible and shallow. ”

Liu Wei smiled, was praised by him, and then said:

"Eating, dressing, reading, that's all there is to it. Although General Cao relaxes, if you are a capable official like you, there are still many opportunities to leave your name in history. ”

The words are fluttering, but they are full of pies......

Oh no, promise!

Cao Cao's eyes lit up when he listened, but Liu Wei's eyes had moved to the government office in front of him.

Suddenly, a gust of wind blew, and the person who covered it could not open his eyes.

When this August wind passed, there was a panic in front of the government office.

It turned out that the flagpole of the big banner in front of the yaqian was blown down by the strong wind, causing a burst of chickens and dogs to jump.

This scene was seen by the emperor, and Cao Cao was embarrassed.

Who knew that when he turned around, he saw that the little emperor had an excited face, and his eyes were full of surprise......
