At this moment, Wang Ju's ten books of elementary mathematics arrived in the capital.

There were too many math books before the Song Dynasty, but this math book was different. Long before it came out, many advertisements were made on bamboo paper. Therefore, as soon as it was released, it aroused the curiosity of some people.

In fact, the past and present are the same. We cannot simply use respect for foreign countries to beautify foreigners. At least putting aside military affairs, the Song Dynasty has stood at the peak of this world in terms of culture, technology and economy. But why are the cotton cloth, glass, Goryeo secret colors, Japanese swords and paper fans, and Xia Guojian so famous? Really, the secret colors of Goryeo celadon has surpassed some porcelains of the Song Dynasty? For example, Xia Guojian. In fact, the Taoxi sword produced by Wangjiazhai later surpassed the beautiful quality of Xia Guojian, and there are many styles, but why is the price still not as good as Xia Guojian?

It is mainly imported products, which everyone thinks are rare.

The same is true. Now Wang Ju uses foreign characters to solve mathematical problems, so let’s see how he solves it. This time, such a thick mathematical book will always have comments.

And it's really inexpensive.

It was only a long time since it was in the market, but it only cost more than 900 articles to be real. You should know that a thin unnotated "Book of Changes" costs more than 100 articles. Therefore, some people immediately bought it, and some people were watching. However, those who bought it immediately discovered the surprise.

This math book is not only about mathematics, but also about too much water.

For example, when talking about the principle of triangle, Wang Ju deliberately asked a question, trying to look at it thousands of miles away and go to a higher level. Then he drew a picture and included a text saying that the earth may be round. The sun is the heart. The moon turns with the earth, and the earth turns with the sun. This can explain many astronomical phenomena.

Then I asked, if you really stand high, you can see far, and use this topic to explain the principle of eyeballs, and the difference between myopia and presbyopia.

For example, the question of using a pot to carry the growth of plants is to absorb some water and a little soil. However, the plant is split and thrown away the water. Its actual weight exceeds the soil it absorbs. So where does these nutrients come from? So the light one is the upper and the turbid one is the lower one is to explain that the air is not vacuum, and there are many substances. Then give some examples, such as the combustion of charcoal, etc., to explain some substances in the air.

Strictly speaking, it is the combination of primary school mathematics and nature.

But what involves science is just a rough explanation, not a detailed explanation.

In addition, we also talked about abacus and talked about the gantry accounting method that is more advanced and simple than the four-pillar settlement method adopted by the Accounting Department of the Sansi Accounting Department of the Song Dynasty.

This is a good thing.

Some merchants immediately smelled the value of it. Even Sansi envoy Tang Jie heard about it, but when he sent someone to buy it, the ten math books could no longer be bought on the market.

Tang Jie is also famous for his big mouth.

He immediately wrote a letter to impeach Wang Ju. This book is beneficial to the country and the people. Why didn’t Wang Ju hand it over to the court, but used it to make profits.

Zhao Xu was worried about the situation in Yanzhou and said angrily: "Tang Qing, this book is only eight hundred texts for merchants. Do you think it can make profits?"

"Then why not hand it over to Sanshi?"

"I have a set here, so you can take it first. Besides, the carving board is still there and it will be printed next year, so why bother to worry?"

"But I think it's best to name it as the Elementary Sutra."

"So it is named elementary mathematics. It is a science of numbers. Do you think it can replace Confucianism, Taoism and Buddhism?"

"This won't happen." Tang Jie replied honestly.

"That's it. I will say to Wang Ju and ask him to print a few hundred more books and distribute them to the three departments and various transshipment commanders."

Tang Jie went down with this set of books in his arms. Zhao Xu came to Jixian Academy and found Wang Ju who was studying the book, and asked, "Why is it named Mathematics?"

No matter what, it is always a bit bad when you learn.

"Your Majesty. I have always said that for thousands of years, everyone has misunderstood the strange tricks and tricks. Even Zhuge Liang's wooden ox and flowing horse have been lost. If this thing is available, it will save much manpower in the mountains."

The main reason is that the wooden ox refugees have become a myth. Without anyone pushing it, a large group of wooden oxes and refugees run with goods, which is of course "lost". In fact, at this time, the people of Bashu also invented two kinds of cars, "There are small cars in Shu, and they carry eight stones in front of them, like cow heads; there are also large cars, which are pushed by four people, carrying ten stones." In fact, they can be regarded as wooden ox movements. But how do you compare with the legendary wooden ox movements?

Therefore, Zhao Zhen was silent and said, "Mr. Wu is so clever, but you are not much inferior."

Wang Ju laughed and cried, yes, compared with the legendary Zhuge Liang, he is definitely inferior...

He also said: "So, when I use my students to name them, I want everyone to pay attention to it. It is learning, of course, it is just a primary school, but it will be of great use when it comes to economics and people's livelihood. For example, this time, I practice water conservancy because I use my mathematics and the waste is not serious. This alone may save more than one million guan of money."

"What you said is that at least it is an elementary school. The Sansi sent Tang Jie to find me and wanted to ask for this book. I also agreed and asked you to send someone to reprint it and send hundreds of copies to Sansi at that time."

"Okay, it's not that I don't send it to you, but I'm worried that they won't like you. If you like it, it doesn't cost much money to send hundreds of books. I immediately wrote a letter to Hangzhou and asked them to print it again. I will deliver it to the Sansi next spring. But your Majesty, I will go back too."

"Your second uncle has returned to Yanzhou, so don't be so anxious."

"This time Wangjiazhai suffered heavy losses..."

"I have issued the third edict to ask Lu Shen, Zhao Zhong, Gui Niang to bury, and Wang Quan, the patriarch of your small village, to come to Beijing to inquire with your lord."

In other words, I plan to breathe a sigh of relief for Wang Ju.

However, Xixia did this very stupid thing. In this era, people said that life is at stake, which is a fool, just like the Qi people of the Song Dynasty.

But there is one thing that is no less than the law of nature, that is, to be buried in peace.

If you die, don't bother him, and even comment less. But Sima Guang did not take it seriously. As soon as he came to power, he immediately demonized Zhao Xu, who had just died. So this incident had a deep impact on Zhao Xu's two sons, Song Zhezong, Song Huizong! Song Zhezong could be more rational. Song Huizong directly erected a monument. Didn't you errify me? I erected a monument and defeated you all. The first one was Sima Guang, and the second one was Wen Yanbo. Then there were Lu Gongzhu, Lu Dafang, Liu Zhi, Fan Chunren, Han Zhongyan and Su Dongpo, etc., including Zhang Dun, who opposed Song Huizong's rise to power, and Zhang Shangying who was against Cai Jing.

Therefore, after the matter came out, almost all the congressmen and ministers closed their mouths together.

Peace is good, but Xixia is so crazy, can we hope that peace will come?

However, it has a profound impact, not only has it made the peace minister shut up, but also the mentality of many people.

"That minister has to avoid it even more."

"No need for this."

"Your Majesty, it is useless for Your Majesty to stay in the capital. The difficulty lies in Shaanxi. Now that Han Gong is in charge in Shaanxi, who dares not accept it? Fangchang Hedu and the 28-point system are implemented smoothly, and there is no need for me. However, this incident happened, the people of Wangjiazhai could no longer stay in Wangjiazhai. As Zhao Zhong said, if they want their safety, they must migrate to Zheng Baiqu. But from the Security Army to Zheng Baiqu, they are far apart. The people must bring their family property and even the bodies of their ancestors. It is really not easy. I must help them."

"Can you be resettled in Yanzhou?"

"Your Majesty, Guo Kui will probably be safe when he goes to Yanzhou. However, the good and bad officials in the court are mixed. Even if Yao and Shun are reborn, it is difficult to distinguish one by one. If an official like Lu Shi goes to Yanzhou again, even if he moves to Yanzhou, there may be a tragedy. Especially my grandparents and fathers have been insulted once, and I don't want them to be insulted again in the nine fountains."

Zhao Xu was speechless.

In fact, sometimes he really dares not think about these things.

It's okay if the corpse of his confidant ministers was dragged out by the enemy, but it's okay if he didn't save him. In the end, he had to fight for a thousand successful foreign cavalry, and it's okay if he had to fight for the foreign cavalry. There were many important officials in the court who supported him and took the initiative to cover him up.

Is this my Song Dynasty?

"And Zheng Baiqu. I have to take a detour to comfort me. Spring is about to begin, so I can't miss work anymore. Xixia is eccentric, peace is hard to find, and Suizhou is lost out of thin air. In the future, wars will happen, but the size is just the size. However, when the war breaks out, the most troublesome thing is food and grass. The early completion of Zheng Baiqu and late completion are not only the problem of saving wages and money, but once the war starts again, I don't know how much money and money will be saved."

"There is Han Qi in Shaanxi."

"Han Gong agreed to build the canal, but his attitude towards the merger of hidden fields will be unclear."

"Huh."

"I heard that Mr. Han has thousands of hectares of property..."

"Thousands of hectares!" Zhao Xu was shocked.

"Han Gong was prime minister for many years. Since Renzong, officials' salaries have been even higher in all kinds of salaries. Han Gong could not use money and silk, so he had nowhere to go, so he had to manage land. How much will he get as the Prime Minister for so many years?" Wang Ju said lightly. I don't know if the land in Hanjiazhuang has spread to Neihuang County. In that case, the land is not calculated in acres, but in a mile, and the maximum length can reach more than one hundred miles.

"So, when it comes to mergers, Han Gong has another attitude. Our dynasty does not oppose mergers, but the damage caused by hidden land after the merger is the most serious. The people have no way to survive, and the population will expand quickly. Then, in a few decades, if a major disaster occurs, there is no need to deal with foreign aggression, and the internal collapse will be collapsed."

"This population..."

"Your Majesty, have you told Your Majesty about the population at Xiangguo Temple? It is okay to guide you. Not only in the south, but in the north, but the specific ministers have not thought about it. Moreover, the top priority of the country now is not the population, but the finance. You have to do things step by step, and you cannot be too rushed."

"Slowly."

“In-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-Pre-P

Maybe Zhao Xu is still young and lacks thinking ability and control ability, but he is also impatient. Faced with the current problems of the Song Dynasty, the pressure can be imagined.

But Wang Ju didn't want him to die young.

Don't delay it for four or five years, and it will be fine.

Otherwise, with Sima Guang's desire to hold revenge, not only Wang Anshi, but also himself would be even more miserable.

"Then let's go," said Zhao Xu.

"But before leaving, I will say something, Your Majesty, please listen, and you cannot speak to the outside world. It is very difficult for the country to suppress hereditary, but you can moderately control hereditary. This is not difficult. Your Majesty will make a transition in the first few years. When the transition is completed in these few years, you can control three people and three families."

"Three people and three families?"

"Wen Hanfu, Lv Hanfan." (To be continued)
