I always feel a little sad when I know the later history. First, Zhao Pu and Zhao Kuangyi fought with him. I don’t know how many big shots fell down in the middle, or even how many people died. Those who died were not as good as the historians, and they would not be recorded in history. Then, the father and son of Zhao, three, and three Zhao, etc. In the end, even Zhao Kuangyi’s son couldn’t stand it and began to be crazy about gains and losses. This trend is much more powerful than the bulldozers that started business and commercial enterprises. They rolled all the way, and God knew how many people died.

But now no one will think of it.

Song Jiu couldn't think that he was smart, had a golden finger or an incomplete golden finger. How much did he remember history? If he had not read a few fiction novels, he would probably not even know some of the inside stories of Song Chu. That's it, how many detailed stories of the great Song Dynasty figures could he know? This golden finger is incomplete.

Mathematics, physics and chemistry are good, and I also have to thank my tutor and nephew in college. However, how difficult will it be to transfer the knowledge of my previous life to practical use in this backward era?

Just pretend to be confused. I am just a scattered official and a technical official. Technical officials in the Song Dynasty are not worth much, but in fact they have no rights. What can they do with themselves? Do not get involved!

After thinking it through, he began to give a serious lecture, and even asked Zhao Dezhao a name, "If you don't understand anything, please ask a question."

Lu Duan nodded secretly. He didn't know what Song Jiu was thinking. He thought it was normal. What an honor for the prince to come to study. Xiao Jiu was so scared that he was a little silly. However, he was still very brave. He returned to normal after a little squeezing himself. He was also very smart. Otherwise, if someone else met that Western old man, he might not have learned any knowledge.

His ideas should be reported to Zhao Kuangyin, and this evaluation will also be used as a reference for Zhao Kuangyin to read Song Jiu in the future.

After the class, the little girl asked her brother to take her out for a long time to come back yesterday. At this time, the common people had many children and were not interested, and they had to be busy with their livelihoods, so the children were dispersed. Song Jiu also dispersed, asking the boy to take the little girl out to play, and only warned them not to play with water and fire.

Boys are called big dogs and girls are called puppies. This is how it is. The children of noble families are also cheap to be named. Song Jiu was called Jiuzhu. When he was a child, he became fat and had a lot of meat. Because several children died in front of him, the father simply chose a popular and very "subtle" name called Song Jiu, that is, Tongjiu, hoping that Song Jiu would survive. Song De did not expect that this name would bring great benefits to his son. Song Jiu, Song Jiu, and Zhao Kuangyin established the country as Song. Can you be unhappy to see this name?

It's okay for boys to call dogs and pigs, but it's always a bit bad for girls to call puppies. Song Jiu wanted to give them a name. However, the old woman might be from Northern Han, and her son and daughter-in-law died early, and her personality became weird and taciturn. She should not enter the world if she was a child. Or she subconsciously saw that the more prosperous the capital of the Song Dynasty, the more she hated her, and Song Jiu was too lazy to be troublesome.

The little girl didn't know why she stopped playing outside. She ran home and saw Song Jiu stretching out her hand and saying, "Dad, hug."

Song Jiu had no choice but to hug him.

Zhao Dezhao asked in surprise: "Chengshilang, are you married?"

Song Jiu was about to squirt blood, don’t mention this. When he mentioned the bitter tears, he gritted his teeth and said, “Your Highness, ask your second emperor for the story in the middle.”

"The Second Emperor asked you to get married?"

"Prince..." Song Jiu couldn't continue.

"Chengshilang, I listened to the class for two days and found that this course is also profound."

"Your Highness, that course is profound and profound," Song Jiu said lightly. In fact, it is not just profound and profound in my heart. It is so profound that it is so profound in my heart. But it cannot be said that Confucianism is not as extensive as mathematics, physics and chemistry. Confucianism is philosophy, and it is also profound in depth, but they are two different fields.

"The Chengshilang can consider several books."

"It's so expensive to publish a book..." Song Jiu shook his head. He asked for money everywhere, such as Hezhou's compensation, and half of it was not paid, and he could not get the land deed without paying it. This is always a bit uneasy. And where can I write it out?

"If Chengshilang publishes a book, I am willing to sponsor you with all my strength."

Zhao Dezhao may not have much money, but he still has the financial resources to sponsor Song Jiu to publish three or four books. However, Song Jiu said, "Thank you, Your Highness."

Without a clear agreement, observing the study can pretend to be confused. If they publish a book together, they will be even deeper and cannot agree. After talking for a while, Song Jiu always maintained a respectful and distant attitude and talked to Zhao Dezhao. But it is possible that Song Jiu's lecture today was easier to understand. Zhao Dezhao not only had the idea of ​​inspiring Song Jiu to publish a book, but also heard it. He kept hearing it until the class was over in the evening. He did not go to the river bank to watch the big scenes of thousands of people listening to the study. Instead, he followed Song Jiu to the experimental house.

Several soldiers on duty saw Zhao Dezhao and knelt down on one leg together to salute. Of course, they would not refuse to let go. Not only Zhao Dezhao let go, but Eunuch Liu let go, and Lu Duan let go.

Song Jiu thought about the treatment of his sisters, but he was speechless.

I brought it in and now I mainly studied two techniques. The first is cement. Thanks to his high school physics teacher, who taught very lively and often used some simple experiments to deepen the impression of students. Including Song Jiu's teaching methods now, most of them are learning from this teacher.

Among them, there are several methods of making handmade cement. The first is lime slag cement. The residue is burned with coal first. The more the sintered, the better the quality. Pick out the white and red slags, wash, dry and grind it finely. This is difficult. It is estimated that a large amount of high-quality slag must be obtained after the blast furnace comes out. Then use the quicklime from the new kiln to stir-fry the raw gypsum in the pot and fry it into half-water gypsum. The three materials are evenly matched in a certain proportion, and then it becomes cement. If the manufacturing standards are standard, it can be equivalent to the quality of two or three hundred grade cement. The cost will be relatively high, but it is the best choice in this era.

The second type is brick and tile powder cement. Wash and dry the tile brick and ceramics, crush them, grind them finely, and treat lime and gypsum in the same way as the previous method. Together, it is brick and tile powder cement. The higher the composition of brick and tile clay, the better the effect. If the clay ratio can reach a high point, the cement strength can far exceed the former. Or use white porcelain pieces instead of slag and tile powder, as long as the ironware is not touched, white cement can be made. The last type is not considered. Consider the first two. The advantages of this kind of earthen cement are good water resistance, good acid and alkali corrosion resistance, and the disadvantages are more obvious. The cost is high, the strength is low, the freezing resistance is poor, and the solidification speed is slow. Therefore, there will be many constraints when using it. First, it cannot be constructed in winter. Second,

It must be maintained for about twenty days after the construction is completed. Third, the ground must be increased in lime. When burning beams, columns and slabs, the number of steel bars can only be added regardless of cost. The four seasons can be used in Beijing, and then heading north, especially Yanshan to north. This kind of cement is not very suitable, but it is just right to go south. Its quality may not be able to catch up with the glutinous rice flour lime used at this time, but the three-dimensional soil has more disadvantages. First, the construction time is longer, and the cost of strict standard three-dimensional soil is also higher. The biggest disadvantage is that it cannot be matched with steel bars. Cement is poor, but it is different with steel bars. It can make the building taller, stronger and stronger, and at the same time reduce its own quality.

If you want to build a tall building or a blast furnace, you have to need cement, even if it is this kind of primitive cement.

It's easy to say, but difficult to develop.

Generally speaking, its solidification is only equivalent to standard cement of 200 No. 200 No. 200 No. 200 No. 200 No. 200 No. 300 No. 400 No. 400 No. 400 No. 400 No. 400 No. 400 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No. 100 No.

There is no technical difficulty below.

Whether it is iron smelting or porcelain with good quality in the future, one key factor is temperature.

If you want temperature, you must have coke.

This appeared earlier, and seemed to have appeared in the late Southern Song Dynasty. Now Song Jiu has not seen it. It is simple or simple. As long as bituminous coal is heated under air condition, it can be made by drying, pyrolyzing, melting, bonding, solidifying, and shrinking.

But coke also has good or bad. The first thing is to distinguish the types of bituminous coal, long flame coal, gas coal, fat coal, coking coal, lean coal and poor coal. The coke situations of each are different. If you want to make good coke, you must identify them and then match them.

Then carry out various technical research and development.

Another problem that Song Jiu cannot solve is that the sulfur content. If the sulfur content is high, the sulfur will be brought into the iron smelting, and the iron quality will be poor. With the current conditions, how could Song Jiu de-sulfurization? It can only be said that using blast furnaces to smel iron, the iron smelted must be better than those small earth furnaces in Hebei, and there will be no serious waste.

As the officials who studied reported, the court gradually paid attention to it. Now there is no need for Song Jiu to buy materials. As long as Song Jiu gives an order, Kaifeng Prefecture will send someone to send relevant materials to save time for Song Jiu. There is no reward yet, and this is indispensable. Once successful, it will be the time when the court issues rewards.

The yard has a lot of things. You can’t build blast furnaces, and you don’t need to build blast furnaces. Various basic technologies have been developed, and better steel can be found. But there are not many gunpowder, only a few kilograms of pounds for explanation. Otherwise, the test is inseparable from fire. It’s too dangerous to put gunpowder in front.

Song Jiu led the students to make trouble, and Zhao Dezhao lay down beside him to watch and kept asking. Even because he was young and wanted to help, Song Jiu dared to ask him to help and went back immediately, looking dark, Zhao Kuangyin was sure to be anxious about him.

Use your arms to block him and prevent him from taking action. You can see, ask, and you must not reach out to touch him.

In fact, when Song Jiu broke up the city wall, he brought his students to research and development. Both of them had some clues. When it was almost dark, the group went back. Song Jiu did not dare to keep Zhao Dezhao for dinner, which was really out of order.
