On the sand, a few symbols are drawn crookedly.

The little boy in the lead pointed the symbols with a wooden stick and chanted: "1, 2, 3, 4......"

There are only nine symbols in total, and when it comes to the tenth number, 1 and 0 together can represent ten.

It's a little interesting, Li Ergou smacked his lips and continued to watch with interest.

The surrounding children also saw Li Ergou, but these children were brought back by Gu Lan, and they have not yet fully integrated into the village, although they usually participate in labor, but they don't have the heart to participate in the village gossip.

One child even gave up a place for Li Ergou.

“1+1=？”

Liang Er wrote down a string of symbols, "This + is the meaning of adding up, for example, Goudan has a cake, I have a cake, how many cakes do the two of us have in total?" ”

The question was so simple that the children said in unison, "Two! ”

"Yes, my sister said, this is mathematics, it is too difficult to express it in words, so she thought about it, and used these symbols instead of one, two, three, four, five, you see, isn't this much simpler?"

It turned out to be Gu Lan who came out of it, and Li Ergou heard a familiar name.

He shook his head, looked at Liang Er and then looked at the children next to him, and the children suddenly realized, "Sister Lan is amazing!" ”

"Of course, my sister is much smarter than me."

Liang Er puffed up his chest proudly, "Your task today is to learn addition and subtraction within ten, and if you learn quickly and well, you will be able to get more food!" ”

Gu Lan didn't raise the children she brought back in vain, she wanted to train these children to become talents, not her slaves, so she naturally wanted to teach them the truth of doing it themselves.

These children are relatively weak and cannot do physical labor well, so they can only let them study, who says that learning is not a kind of labor.

Children learn things faster than adults, and when they learn math well, there are still more places to use them.

So, Gu Lan took time to give Liang Er the Arabic numeral church in her previous life at night, and Zhu'er fell asleep after listening to it for a while.

Liang Er then taught the children the simple math they had learned.

Liang Er is really smart, he learned the rules of numbers in one night's hard work, learned to read numbers within 100, addition and subtraction within 50, and taught these zero-based children more than enough.

One reads, a group of people read, Li Ergou is also among the children who are reading, he looks at these tadpole-like numbers, and feels as if he knows a whole new world.

The numbers were like tadpoles, like fish he was familiar with, constantly beating in his mind, and then sitting in a fixed position.

“51、52、53……”

The children read in unison to fifty and couldn't continue, but there was still one person reading down.

All the children looked at Li Ergou in unison, and he looked seriously at the sand, where there were only nine simple symbols, but he seemed to see countless numbers.

“99、100……”

What will be a hundred years from now?

Li Ergou looked at Liang Er, and Liang Er said, "Another cycle, 101!" ”

Yes! It's another cycle! Li Ergou's mouth suddenly opened, and the feeling of enlightenment was like an overelectricity, seeping out from his limbs, every pore was open, excited and active, like finding a game worth dedicating his life to.

He kept reading down until he got to five hundred, six hundred, seven hundred, until the number 999.

"It's a thousand's turn." Liang Er reminded in a whisper.

So Li Ergou began to continue reading, it turned out that after a hundred is a thousand, what about after a thousand?

He asked Liang'er curiously.

Liang Er's face was embarrassed, "I don't know about this, my sister only told me ten hundred thousand, if I can master these numbers within ten days, it will already be very powerful." ”

Liang Er said, almost crying, his sister has been praising him for being smart, but the forty-year-old Li Ergou in front of him is obviously smarter, and for the first time in his life, Liang Er has a feeling that his IQ has been crushed.

Li Ergou smacked his lips unsatisfactorily, "It's really interesting, your village is really interesting." ”

As he spoke, he tried to get up, but his legs went numb and he sat on the sand.

Li Ergou's leg was already injured, and now he was even more unconscious, and he yelled in a panic, scaring the children into scattering like birds and beasts.

"Run! Li Ergou is crazy! ”

On the mountain road, the snow was falling, and the group walked on the muddy road with difficulty, Zhou Yang's wheelchair was gone, and he sat on the wheelbarrow, being pulled with difficulty.

Seven or eight wheelbarrows were brought out, all of them were gone, wheelchairs were gone, plus half a month of eating and sleeping in the open, all the people in the caravan were dusty, but their faces were full of joy of harvest.

The head of the ram saw the stone arch bridge and knew that the village was almost there, and his voice was hoarse but full of excitement: "Hurry up, work harder, I will go back soon!" ”

When passing under the naturally formed stone bridge cave, he subconsciously looked up, and heard that last time Gu Lan wanted to climb up and find a yellow flower, after going back, his brother told him that when he passed this bridge in the future, he would take a closer look to see if there were any yellow flowers.

It seems that there is none.

"It's good to be home!"

"That is, if they knew how much money we made, they would be happy!"

Everyone in the caravan was chattering, and Zhou Yang also had a satisfied smile on his face.

The ram slowed down, followed Zhou Yang's wheelbarrow, patted him on the shoulder and said: "It's just that Brother Yang is suffering, there is a mount when you go out, and when you come back, you can only let people push it!" ”

Everyone laughed, and Zhou Yang also laughed, not angry.

This time they harvested a lot, the wheelbarrow made by Zhou Yang was very useful, and many people were moved after seeing them pushing a cart by themselves, which could hold a lot of food and tools.

At this time, working in the fields depends on men to support a family, and it is okay to have cattle at home, but there may be very few families that raise cattle, and it is difficult to even feed people, where can you still raise cattle.

Therefore, all the hard work is men's, a wheelbarrow only costs two taels of silver, and the role played is comparable to that of an adult man, and women and children can push the wheelbarrow to work in the field as long as they master the skills.

Since the last time Xiaolongkan announced that the kudzu could be eaten, the villagers of other villages quickly learned the news and began to do experiments, and sure enough, the soaked kudzu tasted non-poisonous.

Without grinding into powder, kudzu can be eaten when steamed, and it is particularly easy to eat and satisfy, and for a while, many people began to dig kudzu up the mountain.

As soon as the caravan went to the various villages, the banner of Xiaolongkan was unfurled, and some people asked curiously, and then the caravan demonstrated.

Hardly anyone can resist the allure of a wheelbarrow.

Some people have money at home, they can afford to buy it through gritted teeth, and now they have kudzu to eat, as long as they survive this winter, but some people are just waiting and watching.

In any case, there were quite a few people who wanted to buy unicycles, and they not only sold out the unicycles they had taken out, but also received more than a dozen orders.

In ten days of hard work, the group earned more than sixty taels of silver, how could they not be happy.
