When Song Jiu returned home drunk, it was almost three o'clock. He didn't say that, more than a dozen people tried their best to drink him. In fact, Song Jiu had a good alcohol tolerance, but a hero could not beat four-handed people, and more than a dozen people were knocked down in a while. It was not really poured down, but pretended to be drunk and vomited. More than a dozen people laughed and let him go. But it means that they recognized him, and this recognition was rewarded by Zhao Kuangyin.

The eunuch sent Song Jiu to have tea and chat. After a long conversation, Zhao Kuangyi deliberately turned over Song De's deeds. The emperor and the crown prince did not take it seriously because they were close guards of Chai Rong in the former Zhou Dynasty, and no one dared to say it. The emperor and the crown prince agreed with them. Their fathers were not only Zhao Kuangyin's subordinates, but also Chai Rong's subordinates, so they also recognized Song Jiu. They were their own people and could not be considered as grass-roots people.

Song Jiu did not dare to tell the bet, but said that the emperor agreed to let him do a pilot project of several hectares of land in Hezhou, and hand over some money and silk a year for him to manage it. More than a dozen people could not hear clearly, and although they were curious, they did not take it seriously for the time being. However, after the "warning" was needed, Song Jiu started to pour Cao Can, and Cao Can, who was only fourteen years old, fell down. Pan Weide sent someone to send Cao Can back. Song Jiu didn't know if Cao Bin would suck Cao Can's butt, so he came again. Seeing Song Jiu came out, he continued to pour it. It didn't count. But an unhappy scene happened at the banquet. Zhang Qiong's son was also not old and poured Cao Can. Everyone wanted to pour Zhang Qiong's son Zhang Lin, but for some reason, Zhang Lin and Fu Zhaoshou were fighting for it and almost blushed.

At that time, Song Jiu had almost finished drinking and persuaded him a few words. The trouble broke out and it left unhappily. Then Song Jiu returned home in a daze.

The door of the house was still open, and Zhu San was waiting for him in the living room of his house, and there were other people, ten students, and Eunuch Liu. There were still many cloths in the corner of the hall. The Song Dynasty lacked copper coins from beginning to end, so it had to use cloth instead of money, or barter from some remote areas.

Copper coins were very bulky. At this time, the Song Dynasty itself also began to cast coins. The amount was not large. Sometimes it was tens of thousands of guan a year, and sometimes it was only a few thousand guan. Most of them were used for the copper coins of the previous dynasty. Even if the copper coins of the Sui Dynasty were well kept, they would still be circulated now. On average, the guan coins weighed more than seven jin. In other words, if a man carried 15 guan coins, he would be exhausted after walking ten miles. But cloth was even more troublesome. One piece of silk was worth more than one piece of silk, one piece of silk was ten zhang, and ten pieces of silk were one hundred zhang. That was heavier and more burdensome.

The results of the competition came out a little late. There were several companies with a lot of books. It was not until dark. Some disputes arose in the middle. The students said I was right, and the accountant said I was right, so they re-verified and re-calculated. The whole thing was delayed until nearly two updates.

Fortunately, Zhao Kuangyin was foresighted and sent guards to watch. Otherwise, the accountants might have let the shopkeeper beat these students up in anger.

As a result, eight students won, and two students failed, not as fast as others. The main reason was that they had settled the accounts some time ago, and the students calculated the single-type accounting books they were not familiar with, and they didn't recognize some of them, so they fell behind.

Eunuch Liu reported the result to the palace.

Pan's house was not far from the palace, so Zhao Kuangyin rewarded each student with ten coins of money and ten pieces of silk. But he asked Eunuch Liu to come to the Song family to bring a few words.

Song Jiu staggered and wanted to pour tea for Eunuch Liu, but Eunuch Liu helped him: "Jiulang, let the Sa family come."

He didn't let him come, so Zhu San snatched it and cooked strong tea for Song Jiu to relieve wine.

Song Jiu pointed at ten students with his fingers: "How did you end up?"

As a result, Song Jiu shouted out the two lost students and scolded them loudly. Not to mention arithmetic, with chalk, abacus, and abacus. With this, he was ten times faster than those accountants. How could he lose?

The two students were about the same age as Song Jiu, but they were knowledgeable and chatted with the emperor. They were Jie Zi and their teacher, so they had to admit their mistakes.

Eunuch Liu stopped him: "Jiulang, it's very good. When he heard the result, the officials were shocked in the palace."

Song Jiu was still furious and punished the two students to go home for half an hour later. If you play, you will make trouble, but learning is a very progressive educational method, but unfortunately no one pays attention. But Eunuch Liu was slightly amazed, and it turned out that Song Jiu's education was also quite strict.

Eunuch Liu took out a small green robe, white silk mid-single robe, white silk trousers, white silk square heart curved collar, and a two-beam crown, which is Song Jiu's official uniform hat, and the clothing inside. He, a small scattered official, cannot go to court or speak, but he also wants to attend some of the great priests, and he is also used to give him a crown. But in this official uniform, Zhu San's eyes were green and his face was envious. He was a scattered person in charge of agriculture, industry and commerce. The official-oriented thoughts in this era were too serious.

Song Jiu said, "Thank you, Your Majesty."

Eunuch Liu told Zhu San to make tea for Song Dynasty, and she had to drink some tea to make Song Jiu clear. After sipping the tea for a while, Eunuch Liu said, "Jiulang, Your Majesty said you won, but three years will be quick. No matter how you manage it, don't violate Song's rules, otherwise you will be severely punished."

Song Jiu said that the three pictures were just a guess. Zhao Kuangyin thought it was random guesses, with only 10% doubts, and no 10% of the belief. But he believed in Song Jiu's bet. Only 10% of the time.

A irrelevant little river in the past can produce 100,000 yuan in a year, so how can the entire capital be at least 10 million yuan in a year? Can the Song Dynasty be at least 100 million yuan in a year? Among them, Wang Anshi's reforms to make money at the highest rate of 180 million yuan in a year. There are pieces, stones, buns, and twelves, but on average, more than 100 million yuan, which is more than 7 times the annual income of the highest country in the Tang Dynasty. If the capital was seriously taxed, all the industries of the dignitaries would be law-abiding citizens, and the capital could also collect more than 2,000 yuan in a year. This number would be killed by the Zhao brothers, and the Zhao brothers would not believe it.

Zhao Kuangyin was worried that Song Jiu would use this bet to cheat, but he didn't care too much. It would be okay to cheat tens of thousands of coins, but he could cheat millions of coins? The court did not have the ability! So he only asked Eunuch Liu to give a brief warning.

In fact, Zhao Kuangyin did not expect Song Jiu to accumulate more than 4 million yuan in the next fifty years, and this bet would be a huge advantage in the court.

Let him make trouble first. Anyway, I am only in my thirties and can see it. I can see how he can't do it in the future. But Zhao Kuangyin didn't know that there was no sign of the eight characters, and Song Jiu was owed more than 10,000 yuan in debt.

"Eunuch Liu, please rest assured, will I violate Song Lu?"

"That's good. Your Majesty also asked the Sa family to bring you an order."

"Please give me instructions."

"Your Majesty asks the Sa family to inform you that the answers to those three questions cannot be revealed, and the court will have other functions."

“What is the purpose?”

"south."

Song Jiu drank a cup of strong tea and was a little clear-headed. He realized that the Song Dynasty was very rich in history, especially the Northern Song Dynasty. Moreover, several emperors were not evil, and Zhao Ji and his son could not count it. But they were very soft to the outside world. A rich country that was greedy for life and death was undoubtedly a super fat sheep. Then he gave An to An, and it was 800,000 yuan a year. Tea, silk, and silver. The silver of the Song Dynasty was very valuable. One tael of silver and two jin of money was better. The silk was better. It could be transported to the border, and the cost was nearly two jin, which means that more than one million jin a year was gone. Mai An had been bought for nearly a hundred years.

Now the Southern Tang Dynasty is a smaller version of the Northern Song Dynasty, and it also attaches importance to internal governance. People's lives are not too hard, at least because of the terrain and weather, the crop yield is high, which is richer than the people of the Song Dynasty. Not to mention literature, the Northern Song Dynasty was a giant in martial arts and a dwarf in literature at this time. The Song Dynasty had to pay attention to civil governance, but its civil governance was far less than that of the foreign countries in the south. This made the Song Dynasty feel faceless, so it came up with their own three questions and made it difficult for the Southern Tang Dynasty.

How to operate is not something Song Jiu can ask about.

Song Jiu thought for a while and said, "No, Eunuch Liu, I heard many people in the capital talking about it, saying that I was intentionally making things difficult for others, and it was simply three unsolvable mathematical problems. The time is coming soon, and I must announce its solution. However, if the court wants to have a question, I can draw three more difficult ones."

"This is good, the harder it is, the better."

"But I drank a little too much today, so you can pick up the question tomorrow."

When Eunuch Liu was sent away, Song Jiu fell asleep. When he woke up the next day, Zhu San reminded him that Song Jiu remembered this matter. It is not easy to solve difficult math problems. However, it is not so easy to solve. Most math problems in the upper grades cannot be solved. At least it seems that there is no practicality now. People who read the complex geometry of functions and can't even understand them. How can people convince them?

Just like Han Yu translated the stone drum text, some people might not admit why you have the final say!

Song Jiu wrote the first question: Changshi dredged rivers, and the amount of silt required 200 vehicles towed 24 days and day and night. The government has 250 vehicles, and one vehicle is available for use immediately. One vehicle can be drawn out every two hours, and how many days can it be towed away the silt?

Song Jiu was writing, and Zhu San was watching from the side. After thinking about it, his mind felt a little dizzy.

Song Jiu wrote the second question: The paint of a large iron ball requires 1,500 kilograms of paint, and the size of 64 iron balls melted into giant balls. How much does it take to paint a giant ball?

Zhu San asked suspiciously: "Well, is there such a big iron ball?"

"Prevent people from casting according to the sample and then measuring, rather than counting it."

Zhu San didn't even know the circular volume formula, and he was confused again when he thought about it.

Song Jiu wrote the third question again. The output of a certain workshop increased evenly, and it doubled in ten years. What is the annual increase rate?

"This is easy to count."

"Brother Zhu, it's really easy to calculate, are you going to calculate?"

If it is said that the increase of 10% every year, it will be possible to calculate the increase in ten years, but now it is ten times, which seems simple, but it has become a problem.

These three questions are typical application questions and will not be completely used, but if they can be solved, they will encounter many similar practical calculation questions. Song Jiu put it down and started to have breakfast with Zhu San. After breakfast, some students came to school, and the two doctoral students still have a future.

Song Jiu said: "Brother Zhu, you teach me first, I'll go out."

I came to Beiwazi slowly and saw Yuping. In the future painting of Hezhou, this beautiful beautiful head is also an important chess piece.

Yuping hadn't gotten up yet, and waited for a while before she washed and dressed up, and took Song Jiu in.

Cui'er served tea and Yuping said, "Jiulang, the few songs I sang yesterday are very beautiful."

The tone is a bit sour.

Song Jiu pinched his nose and said, "If Madam Yu likes it, I will make two small orders for you another day."

"The blessing from the I family."

"Miss Yu, I don't have that mind. Don't think about it. I'm here to find you just to join forces with you to do an important thing."

"I'm a poor family..."

"Don't talk about the scene, are you willing?"

"What's up?"

Song Jiu did not answer directly, but asked: "Madam Yu, how much money will the guest give you to the bureau at one time?"
