Teach them......

Instead of teaching it to Yan Jiangguan himself.

Xu Wen quickly heard the meaning of the other party's words, and nodded without thinking: "Okay." ”

Yan Jiangguan was stunned.

He originally thought that Xu Wen would not agree so quickly, and he was going to say a few more words about the opening conditions, but he didn't expect Xu Wen to answer almost instantly. And in this way, even if he didn't say he would pay him, he would have promised to teach these things to others for free.

Of course, Yan Jiangguan will not regret what he says, he will still give it, but his attitude towards Xu Wen is different from before.

"Good. When will it start?"

Xu Wen looked at the scroll in his hand and muttered, "I have to think about how to integrate what I want to teach them with the lessons above. Probably...... Let's start the day after tomorrow, right?"

He asked for Yan Jiangguan's meaning, and Yan Jiangguan looked at him deeply and nodded.

Xu Wen looked at the scroll again and wrote down all the contents on it - anything, if you understand the logical relationship in it, it will become much easier to remember, and this one is no exception.

Besides, the craftsmen used to be a complete wasteland in this area. A month is too short for them to open up wasteland and farm, so they can only lay a foundation.

Xu Wen can imagine that after arriving in the Western Desert, this kind of teaching will continue, and at that time, the imperial court will have a group of such new craftsmen.

Xu asked if such a thing had ever happened in the history of his world.

The craftsmen are too low, the group of people who are always ignored, and there are not no accounts of them, but they are really very few.

In this world, such 300 people undoubtedly represent a big or small change, a new beginning.

To be one of them in the middle, Xu Wen is very much looking forward to it.

After going back, Xu Wen found that his "bed" had been made.

They were so tired that day that when they came back, they collapsed on the ground and began to take classes and exams for a while, and they didn't have time to build a shack.

Now he returned to the pre-determined camp and saw that "the corpses were all over the field". It's so tired that most people just find a place like a tree root and fall asleep.

But there was still a shack under a certain tree, a little smaller than the previous day, and could only sleep one or two people in it.

Jiang Wangfeng and the others were lying next to this shack, and as soon as they saw Xu Wen coming back, they waved to him vigorously.

This way, this way!

There were snoring sounds everywhere, Xu Wen tiptoed over, Jiang Wangfeng pointed into the shack: "You sleep inside!"

"Huh?" Xu asked.

"They gave you a ride!" Jiang Wangfeng pointed to the side again, Sun Si and Chen Wannian just sat up and looked at him, touching their heads a little embarrassed.

“...... Thank you!" Xu Wen thought about it, did not refuse, and thanked them seriously.

In an instant, Sun Si and Chen Wannian smiled even more happily.

It's cramped in the shack, but it's just right for one person to sleep in.

The shed was covered with straw mats, which were dry and soft.

After a day of walking, they had already walked out of the rain range, but their clothes were wet and a little bad.

Xu Wen changed his wet clothes and put them aside, dried his body, thought about it, found a few more branches, and hung his clothes in a more ventilated position.

He searched for a long time to find a suitable spot, and when he looked up, it was already full of branches and clothes, and the cloth was waving in the wind, like flags.

Xu Wen smiled, stared at the clothes for a while, and then turned around and walked back.

His movements were very slow, and as he did it, his mind was still thinking about what Craftsman Yan had told him before.

The content on that scroll is very clear, it is what I want to teach the craftsmen along the way, and more importantly, a system and a way of thinking that I want to help them build.

It's advanced.

But relatively speaking, the expressions and algorithms involved in mathematics are very unadvanced.

First of all, the content on the scroll is half literate and half white, and the content related to mathematics is almost entirely in classical Chinese.

The reason for this is very simple: the people who studied them before and compiled the results into book manuscripts were all elite readers, and their written language was classical Chinese.

But a craftsman like a layman, if you talk to him, he will only stare at you with a confused face, and the language they usually use is all vernacular.

In order for them to learn this thing faster and better, the way of expression must be changed......

In fact, the modern usage is very good, Arabic numerals and various symbols, concise and clear, easy to column, but can it be used directly here?

Xu Wen lay on the straw mat with his head in his hands, his eyes staring at the roof of the shed, and pondered for a long time.

The next morning, the young man continued to go on the road, the young man recovered quickly, and the young craftsmen next to Xu Wen were in good spirits, nibbling on dry food while talking to each other, and the atmosphere was very noisy.

A little further away, the situation of middle-aged and middle-aged craftsmen is also relatively good. They are not as energetic as young people, but they have more stamina. It's been hard work, but it's nothing compared to before, and it's still within acceptable limits.

It's quite interesting that Jiang Wangfeng, he is the heir of Tianzuo Pavilion, and his background is better than others.

But he can endure much more hardships than Xu Wen imagined.

In the past few days, he has not screamed when he is tired or tired, he has gone as far as he should go, the things he should carry have never been shared with others, and he has made a lot of new friends very well.

At this time, the few people around him, Xu asked none of them, and they couldn't name them.

"You get up, come, this is for you!" Jiang Wangfeng turned his head and saw Xu Wen, ran over happily and stuffed a branch for him.

“...... It's beautiful. Xu Wen subconsciously took it and praised.

The weather is getting cooler, and there is frost at night. The frost flowers condensed on the branches, like transparent flowers blooming on yellow leaves, shiny and shiny.

"The frost flowers in the field are better than those in the city. Jiang Wangfeng also held a branch in his hand, held it high, and looked at the sky through it. He was smiling, and his eyes were full of light.

"When we first met, you also stuffed me with a twig. Xu Wen smiled and remembered.

"Yes, I remember that the maple leaves were just red at that time, and in fact, they were more beautiful a few days later, but unfortunately I didn't have time to go. Jiang Wangfeng said.

"It was still autumn, and now it's almost winter. Xu asked.

"It didn't take long. Jiang Wangfeng said.

"Yes......" Xu Wen sighed with emotion, and suddenly asked Jiang Wangfeng, "Your family has been in Jiangnan for a long time, have you ever dealt with Hu Shang?"

"Yes. Jiang Wangfeng said, "I came by boat." Red-haired, yellow-haired, blue-eyed, green-eyed, not used to it at first, but then I got used to it and found that it was not strange, we are all human beings like us, but the taste is a little bigger. ”

"Have you seen it?" asked Xu Wen.

"Yes. Jiang Wangfeng replied naturally. Wu Qiniang's cultivation of him is all-round, and she has taken him by her side since he was a child. He had met Hu Shang many times and dealt with them personally.

Hu Shang mainly spoke Chinese, but they also spoke a language they did not understand.

They come to Da Zhou mainly for business, and their attitude is very friendly, and they often bring some Hu medicine to the locals, and the effect is good.

"When it comes to business, do they keep accounts?" asked Xu.

"Of course, I've seen their ledgers. Jiang Wangfeng said.

"Is their way of counting completely different from ours?" Xu asked again.

"That's right. Jiang Wangfeng said, "They use a kind of crooked symbol, and they can't understand it." ”

"Hmm......" Xu Wen nodded and groaned.
