After ordering the number of people to be counted, Xu Boan was not idle.

He picked a more delicate mortar, used the mortar to follow the "water pipe made of an infusion set" stuck in the rocks, and carefully smeared a layer on it.

Because for Xu Bo'an, this world in the bonsai is like his own backyard, so Xu Bo'an is very meticulous, trying to be smooth without bubbles and without leakage.

The little people soon saw that the transparent pipe that had been exposed earlier was covered by the magic power of the mountain god's grandfather.

"Oh my God, look, what kind of treasure is this?"

"Look, it's a bit like mud and stone for filling leaks!"

"What are you kidding, how can the mud and stone soil have this color, besides, how can Grandpa Mountain God use the things that we ordinary people use."

"Fill in the gaps? It won't be the legendary gods of ancient times, used to mend the heavens and mend the heavens! ”

"Shhh...... Mend the Heavenly God Mud! When you say that, it's really quite similar. ”

"Hey, you said that if we had this thing, would we be able to repair the mud under our feet like the green brick floor in the city?"

"Of course you can, you haven't noticed, these divine mud of the mountain god grandfather looks very similar to the appearance of the rewarded city wall outside."

"I understand, that hard city wall is made of divine mud by the mountain god's grandfather."

"Oh my God, no wonder the walls are so hard that they are as hard as the stones! It turned out to be made of mending heavenly clay. ”

If you want to say that the logic of three people becoming tigers, it can be applied everywhere.

It didn't take long for these mortars used by Xu Bo'an to become the legendary "mending heaven god mud" by default in the mouths of these small people in the bonsai world!

Because of the pursuit of excellence, more than half an hour has passed since Xu Boan finished these tasks.

Yu Guang glanced at it and saw that Li Qingjiang was lowering his head and counting the sticks seriously, and from time to time he was writing some cumbersome handwriting on the rough paper on the side.

"Li Qingjiang, what are you doing?" Xu Boan asked strangely.

When Li Qingjiang heard Xu Bo'an's words, he hurriedly stopped the small wooden stick in his hand, shook the clothes on his body, and said respectfully: "Back to the words of Grandpa Shanshen, most of the villagers are illiterate, and they are numbers replaced by small wooden sticks. ”

Only then did Xu Boan know that the counting method in the bonsai world was still very backward.

Their counting numbers are probably as cumbersome as capitalized numbers like "壹贰叁", and there is no simplified alternative.

Xu Bo'an thought for a moment and decided to teach them the easiest Arabic numerals and basic mathematical arithmetic knowledge.

Soon, Xu Boan tore out a few pieces of soybean-sized paper and carefully wrote a total of 21 numbers from 0 to 20 on them.

Then he said seriously: "Li Qingjiang, I can teach you a simpler counting method and a more convenient algorithm, you listen well." ”

Hearing the words of Grandpa Mountain God, Li Qingjiang was stunned, and he forgot the number of wooden sticks he had just counted.

Li Qingjiang simply put the wooden stick aside and said, "Thank you for the blessing of the mountain god, Qingjiang must listen carefully!" ”

Xu Boan took out a few small cards, gently placed them in front of Li Qingjiang, first pointed to the ten cards from 0 to 9, and said: "Look at it, these handwriting are called numbers, 1 represents one of your small wooden sticks, and 2 represents two small wooden sticks."

And so on, 9 represents 9 small sticks. And 0 means no, for example, a fruit is 1, if you eat this fruit, there will be no more, it is 0. ”

Li Qingjiang nodded with interest and said, "This is a very novel method, which is much more convenient and faster than writing." ”

Xu Boan smiled: "That's right, the most important thing is that the villagers are easy to learn, faster than counting small wooden sticks." ”

Li Qingjiang hurriedly nodded and said: "Yes, I will teach this simple number to the villagers when I go back, but as long as the big guys master a little arithmetic, they can save a lot of energy in life." ”

"That's right, so you'll have to study hard first." While speaking, Xu Boan took out another card and said, "Look, 1 and 0 are put together, representing ten, and so on, eleven and twelve, respectively, represent your eleven sticks and twelve sticks." ”

Li Qingjiang blinked his eyes and said, "Grandpa Mountain God, if you continue, three 1s, does it represent one hundred and eleven!" ”

Xu Boan raised his eyebrows, and said in his heart that he deserved to be a genius, this ability to draw inferences from one another is really strong.

I really don't know, how can such a person have such bad luck and can't even pass the show!

"Yes, that's it. Such a simple counting method is still easy to master, at least not as cumbersome as counting with wooden sticks. ”

Li Qingjiang looked at those numbers and said happily: "Thank you for the blessing of Grandpa Mountain God, with these simple numbers, I don't have to write cumbersome words anymore." Presumably, folks can also learn. ”

Xu Boan said affirmatively: "Yes, you are responsible for preaching and learning for the villagers." That's it, I'll give you another quick counting method, called the ninety-nine multiplication formula. ”

Li Qingjiang said respectfully and expectantly: "Xiaomin listens to you."

Xu Boan said slowly: "First of all, if we want to master multiplication, we must know the application of multiplication in daily life. For example, if there are five people who need to go out to work, and each person needs to prepare two tools, how many are needed? ”

Li Qingjiang blinked, his thumb quickly tapped a few times on his knuckles, and said, "Grandpa Mountain God, according to the question you said, you need to prepare ten tools."

Xu Bo'an nodded, and continued: "Then if thirty-two people are dispatched to do three days of work, each person needs to bring two meals of rations a day, how many meals and rations do these people need to bring in total?"

Li Qingjiang was the same as just now, with a slight dot on his knuckles, but this time it took a little longer.

Xu Bo'an smiled faintly, and was about to speak, when he saw Li Qingjiang stop the movement in his hand and said, "Grandpa Mountain God, it should be enough to bring one hundred and ninety-two meals."

Xu Boan was surprised this time, originally he thought that the first question was too simple, so Li Qingjiang could quickly calculate it, and the number of questions in the second question increased, and the other party might be at a loss, but he didn't expect Li Qingjiang to calculate it quickly.

Good guy, I don't underestimate the heroes of the world!

"Very good, Li Qingjiang, since you already have a foundation, it will be much easier to learn. Let's start simple,

One by one gets one, two two gets four, three three gets nine, which means that one is still one, two two is four, and three three are added together, and it is nine.

With the multiplication formula, you can quickly save the time that would otherwise need to be added. It can effectively improve the calculation speed and accuracy. ”

After Li Qingjiang heard Xu Bo'an's words, he said with a strange face: "Grandpa Mountain God, this nine-nine multiplication formula in the fairy world is not our nine-chip algorithm, one is like one, two is like four...... This...... The nine-chip algorithm is also known to Xiaomin, and it is recorded in the chapter. ”

Xu Boan was stunned for a moment, and an embarrassing feeling was born in an instant.

This is the first time he has embarrassed in front of the villain in the bonsai world.

Well, sloppy.

I didn't expect that there are still multiplication formulas in this place.

Soon, Xu Boan searched the Internet and found that the multiplication formula had already formed a prototype as early as the Spring and Autumn Period and the Warring States Period more than 3,000 years ago.

Well, hold yourself up.

More than 3,000 years ago, the Spring and Autumn Period and the Warring States Period were able to invent the multiplication formula, and it was not surprising that the people of the Dajing Dynasty were able to summarize the nine-chip algorithm.

Xu Bo'an was silent for a while, coughed a little, and then continued to say to Li Qingjiang: "Okay, since you have a nine-chip algorithm, then you can just put the numbers I taught you, and better popularize them to as many villagers as possible, especially children, who must learn it."

Now Xu Boan doesn't know that his decision has achieved the initial prototype of compulsory education in the Dajing Dynasty.

……

"Bang Bang Bang"

There was a knock at the door.

Xu Boan subconsciously put away the bonsai, and then walked to the door of the office and opened the door.

Then, I saw Guo Huaizhu in work clothes standing outside the door.

He was also carrying a black plastic bag in his hand.

"Hello Mr. Xu, I'm really sorry to take the liberty of disturbing you. I wanted to report to you. ”

said that it was a report work, but in fact, the difference in the level of the two was not too far.

Guo Huaizhu's work report has to be two or three levels above to get to Xu Bo'an.

However, Xu Boan still warmly received Guo Huaizhu.

The two talked very happily, most of them were asked by Xu Boan, and Guo Huaizhu replied.

Soon, Xu Boan had an evaluation of Guo Huaizhu.

Pure technical backbone, can be a general who can charge into battle, but not a handsome talent who defends one side alone.

In other words, it can be reused, but it can't be a leader.

But for now, that's enough.

With Guo Huaizhu and Liu Quan's foreshadowing, he can be regarded as a daughter buying horse bones, and he has taken the first step.

Before Guo Huaizhu left, Xu Boan asked him to take away the so-called specialty in the black plastic bag.

Only a small package of mushroom mountain goods was left, and there were all kinds of sun-dried mushrooms in it, which could be regarded as reassuring Guo Huaizhu.

Xu Boan is not short of food or clothing now, he just wants to work and live well, and naturally he will not accept the so-called thoughts of others.

After receiving Guo Huaizhu, Xu Boan glanced at the bonsai again.

The focus is mainly on Li Qingjiang.

At this time, Li Qingjiang seemed to have finished counting the small sticks.

On the rough paper on the side, the numbers 113 and 189 were written in the Arabic numerals of the Church of Xu Bo Angang.

Based on Xu Bo'an's impression of the ratio of men and women in the bonsai world, the number below in front is women.

It seems that there is also a patriarchal phenomenon in the Dajing Dynasty.

But this is also normal, the more backward the civilization, the more labor is valued.

Men have a natural advantage over women in terms of work.

Thinking of the scene of the first 30 or so people, Xu Boan suddenly had a feeling of prosperity.

Yes, that's great.

If you continue to develop like this, you will have the motivation, and one day in the future, you will be able to increase the power of incense every day.

It's just that I have to educate them when I go back, and it's the same for boys and girls, so I don't have a child!

"Li Qingjiang, have you counted it?" Xu Boan asked.

Li Qingjiang hurriedly replied: "Back to the mountain god's grandfather, at present, together with those people stationed on the city wall, we have a total of 179 men and 103 women here. ”

"Well, well done. What should I reward you? Xu Boan looked left and right.

Li Qingjiang hurriedly said: "It is my honor to be able to do things for the mountain god grandfather, and the little people dare not ask for extravagant rewards." ”

Xu Bo'an rarely found an excuse to send things to these villains, so naturally he wouldn't answer this conversation.

After taking a closer look, Xu Bo'an found that it was time for the cooking smoke in the bonsai again, and he had already started cooking.

It looks like these little guys are a little late for dinner today.

The sun had gone down before I started cooking, and I had already started in the middle of the afternoon in the past, and I had finished eating by this time.

Nine times out of ten, it is because of the beer they are rewarded with, which makes them feel full.

Right now, these little guys are in the form of a big pot of rice.

Collective labor, collective cooking and eating.

Glancing at the food in the pot, Xu Boan frowned slightly.

It looks like three pots of multigrain steamed buns.

In the other pot, it seems to be boiling soup, which is really soup.

It was almost a pot of soup that was crystal clear, with a few wild vegetables floating on it, and there seemed to be a few pieces of meat and ham sausages in the pot that he had once rewarded!

Xu Bo'an only then realized that the existing food in the mountain village is really scarce.

Except for the cured jerky made by the little snake's head that he had given them before, and the so-called fragrant meat that was occasionally rewarded.

They relied on the wild vegetables they dug up and the pickles they had accumulated.

Nowadays, because of the drought, wild vegetables are rare, and they often eat soup and rice with some salt.

That's it, it's already a rare food.

In the current drought, with these foods, at least people will not starve to death! This is already the happiness that many people hope for.

After thinking about it, Xu Boan casually took a small sun-dried mushroom and gently broke about a quarter of it before putting it in.

No way, although Xu Boan has already selected the smallest dried shiitake mushroom, it is also the size of a one-yuan coin.

That's bigger than two pigs for these little people.

Once you give too much, it's not easy to handle, not to mention, if you really let go of the supply, some people will definitely be able to eat it.

In an instant, Li Qingjiang saw a large gray thing falling from the sky, which was a lot fatter than the big tree beside him.

"It's a sun-dried mushroom that softens when eaten by soaking in water. The rest, you should understand. ”

Xu Bo'an has seen that they have eaten mushroom soup before, and they must know how to cook it.

Sure enough, Li Qingjiang said with a happy face: "Thank you for the gift of Grandpa Mountain God, Xiaomin will go and tell the big guy, he will be happy." ”

Before Li Qingjiang could report the good news, Li Kanshan, who found something strange, trotted all the way over.

After thinking about it carefully, Xu Boan suddenly found that the old man's body had completely lost the fatigue he had when he first met.

After a closer look, Xu Boan suddenly found that Li Guanshan's body was actually quite good, but his chest was attached to his back when he was hungry before, and he naturally couldn't lift his energy.

These people in the Dajing Dynasty seem to generally have good physical fitness, not to mention Li Qingshi's innate and infinitely powerful outliers.

It seems that weak women like Chen Shishi, or old people like Li Guanshan and Li Laosan, are in better health than Xu Bo'an in the past.

Hiss......

What is the reason for this? Could it be that the evolution of species in this is relatively good?

"Qingjiang, what is this? Isn't it the mountain god's grandfather who has a gift again? Li Guanshan pointed to the large piece of shiitake mushroom and asked

Li Qingjiang nodded and said with a smile: "Yes, grandpa, grandpa the mountain god said that this is a mushroom in the fairy world, let's soak it and eat it." ”

"Mushrooms? Mushrooms are good! It's a pity that I broke a pot when cooking yesterday, otherwise, I would have made something delicious now for the big guys to taste, and everyone has worked hard in the past two days. Li Kanshan said regretfully.

Broken pot?

Xu Boan subconsciously glanced at the cauldron of the little guys.

It's also made of iron, and it's about the same size and depth as the lid of a beer bottle?

Beer bottle caps?

Xu Boan subconsciously thought of giving the little ones a beer bottle cap as a pot.

Then he dispelled this idea.

No, I can't.

It's coated, it's not healthy.
