Many people felt helpless for Song Jiu's laziness, and thought that Song Jiu was selfish and couldn't hate it. In fact, in the final analysis, it is a generation gap of 1,000 years, Song Jiu is true temperament, not so bad, as a person who grew up in the era of peace, he liked to travel in the mountains and rivers in his previous life, and paid attention to eating and drinking, this life made him carry a heavy burden of historical mission, can it be done?

Inspecting in Hunan, it was so bitter, he still took the mood to see how green the mountains were, how blue the water was, and what mission he talked about, wouldn't it kill him. But people are not evil, being a friend is a warm-hearted friend, being a relative is also a relative who cares about his family, and being a teacher is also a responsible teacher. At this time, seeing students care about themselves, just like parents seeing their children sensible, they are particularly moved and have a special sense of achievement.

Song Jiu said again: "What is illusion, it's not your concern right now, most of you will leave the study house in a few months, but it doesn't matter, this study house will always be open to you in the future, if you have time, I will edit the lecture notes into a book, you have time to continue studying, just come and ask for it." ”

"Okay," the students clapped their hands together.

"Let's give a lecture," Song Jiu put out more than a dozen questions on the blackboard for everyone to do, using this to test how far the students have learned.

A little disappointed him, except for a few smart students, the progress of other students is not very fast, there is a person who understands to teach and completely self-study is different, even if these students are not children. This is Class B, and Class A is also not very good.

Song Jiu scratched his ears and cheeks, did he really want to extend the graduation time of the students again?

Before he could think of a way, he first vacated a place in the room next to his bedroom and opened a bed for Tsing Yi, Cui'er looked at Tsing Yi with clear eyebrows, and asked like a curious baby, Song Jiu told him where he came from. Even Yuping was moved and asked, "Are you Han Xizai's servant?" ”

Han Xizai is too famous and well-known in the capital, and Yuping can be regarded as his fan.

Tsing Yi nodded shyly.

"Can you tell us about him?"

Tsing Yi's mouth opened, looking at Song Jiu, Yuping reacted, came to Song Jiu's side and whispered: "Jiulang is also talented, and those Linjiang Immortals make the slave family admire them a lot. ”

"Yuping, don't praise me, Tsing Yi, it's okay, you can tell him about the deeds of Master Han."

Song Jiu walked out of the city, and took advantage of the time after class to ask Li Zhu about their affairs on the river island. It is not over, the amount of work is too large, and the silt is dug up from the water, which is not easy to bear, and it is not easy to lift, which affects the progress. Although the villagers worked very hard and came up with some fast methods, it has not ended yet, and it seems that it will take at least a month, so it can only be said that the big picture has come out. The glass was also burned, but according to the students, it was still not ideal.

Song Jiu was a little dazed, he couldn't say that the sand would burn out the glass, that was too, the sand must be quartz stone sand, what Nanpeng sand, Beipeng sand, as long as the quartz sand can be. Quartz stone is not hard to find. People have long found a large feldspar mine in Zizhou, which is regarded as a traditional Chinese medicine, and if you are interested in finding it, you can also find a lot of feldspar mines in other places, which is also not difficult. The second is trona, which reacts with lime during the firing process and can replace soda ash, and the last is borax, because there is trona in it, which will also react and replace boric acid. Of course, there are differences in raw materials, and some unexpected changes will occur, which can be coordinated by proportions. That's what I've tried and tested.

It should be said that it is the most scientific formula of glass-burning materials in this world, and even built a small pond kiln that can gather temperature, and some coke from the imperial court to produce high temperature. The magnet is also used to adsorb the residual metal particles inside. Aside from being miniaturized and more backward, it was not much different from the small glass factory he had visited in his previous life.

Why hasn't there been much progress so far?

I can only wait until after school to see it in person.

There are more things than that, the wages on Hezhou have to be settled, the seventh sister's house has to go, and the eldest sister has to find a trouble for herself. I also had to report to Zhao Kuangyi, ask about the situation of the steel supervisor, and by the way, ask when the bridge and the wharf will be arranged. There is one most important thing after all, and that is money!

Then I took a test on physics and accounting, and the students did not learn very well.

But if Song Jiu can know the progress of the students, he can decide where to teach, learn from each other's strengths, move back if he learns well, and let them ask questions if he doesn't learn well, and it will take at least four or five days to barely level the progress of the two classes of students.

After school, the weather was fine, and Dr. Yan and Dr. Zhang led a group of students to the riverbank to teach the people.

After the enthusiasm, there were fewer and fewer people who came to watch, and there were hundreds of people, mostly tourists from other places, as well as people on the boat. This matter is what Zhao Kuangyin is most satisfied with, this is called re-education. However, there were fewer people to study, the country gradually stabilized, the wharves became busier and busier, and there were thousands of laborers used in Hezhou, so only nearly a thousand people studied, half of whom were children. But it's not bad, a few months later, Song Jiu recruited students, these students are at least the first grade of primary school, some are smart, and they can have the level of the second and third grades of primary school. Then it's easy to teach. What he liked the most was that some people began to use Arabic numerals for accounting.

This process will be slow, but at some point, quantitative changes will produce qualitative changes.

Song Jiu took twenty-one of his own students to Hezhou.

Three old craftsmen took out the glass, and several students took out the test records. Song Jiu looked at the glass first, it was a little green, not too obvious, and it could only be seen in the sun, and if you didn't pay attention to it, you couldn't see it. It shows that there is not much impurity metal content in it. This could be improved.

It's opaque and chaotic, and there is a sulfur glass bowl in the test room, which cost Song ninety-four yuan. The big food glass products are not very standardized, and some are very close to the glass products of later generations, transparent and shiny, which will be priceless. There are also some that are also chaotic and blurry, with a serious chaotic green, which one can still be valuable, but the price is not high, and a glass bowl that is almost a little bit can only be worth a few hundred dollars. This is from across the ocean, and it will be cheaper locally. This shows that the industry in the West at this time, like the Song Dynasty, was extremely non-standardized. There are also in the Song Dynasty, which are not durable, and some are directly said to be real glaze, opaque, and glaze luster. Although the glass bowl that Song Jiu took as a sample is not the top of the big food glass, it is also considered high-end.

This kind of home-fired glass is several grades worse than it, but fortunately, it is different from the Song Dynasty glaze, and it will not shatter as soon as it is heated. And I have done a test, as long as it does not cause excessive thermal expansion and contraction due to cold and heat, its heat resistance also exceeds that of Dashi Liuli.

An old craftsman said, "Jiulang, there is still a lack of Nanpeng sand. ”

"Lao Li Tou, don't talk about it, what Nanpeng Sha," Song Jiu looked at the record again, and the test was very detailed, not only tested various proportions, but also tested materials from all over the world. Thinking about it, there is only one reason, it is indeed a headache, so can you remember so many things, such as the reaction formula of trona and borax? If you have to make boric acid powder, that's a big problem. I scratched my head, took a pen, drew a few utensils, and a few pipes, marked the dimensions for the three craftsmen to blow. He also brought sulfur and saltpeter, and asked the students to buy some other things. This is the first test, and then there is a second test. With these two tests, it will take at least a few months to be busy.

He also instructed the three craftsmen not to test the proportions, but to continue to test materials of various temperatures and origins, and to remove borax. After doing this, Song Jiu rubbed his head again, who said it was easy, if he was not careful, he played big again.

Then walk out of the house. The imperial court is very realistic, the research and development of gunpowder has been transferred to gunpowder, the steel is debugged in the steel prison, and the soldiers guarding the door have also left, and the eldest sister can come in whenever she wants. Song Jiu was speechless, in fact, in the future development of Hezhou, there will be a lot of things involved, such as what Song Jiu wants to try, boric acid. Use it to turn into boric acid water, which can be used for the skin, with it you can treat many rashes, dermatitis, not the main thing, now the quality of the weapons used in the cold weapon battlefield is very poor, there is a lot of rust, some soldiers are injured, often die because of it. Boric acid water, combined with highly distilled spirits, could save many soldiers from death every year.

However, because Song Jiu did not have much sense of responsibility, he thought of making it, and only then did he think of its role.

I wonder if Zhao Kuangyin will be nervous again when the road arrives?

When they came to the construction site, the people had not yet returned, and they were working everywhere. When the big appearance came out, the height was even higher than he imagined, nearly three meters high, and the entire height was more than half a meter higher than the Bianshui River embankment in the south. This height is an absolute peace height, and if it can be filled with water, then the capital will become an ocean. But the project was not finished, and the few grooves that the imperial court was responsible for were dug very early, and the water was dredged, and the grooves were very deep, and some ships were moored inside. The ditch that Song Jiu was responsible for himself was also dug up, the tips of the river island were all removed, and several small artificial lakes were also dug up, but there were piles of uneven mud everywhere, which were not completely leveled. And the pipes were laid. This is a remarkable project, starting with the construction of a half of the embankment in the south of the river, allowing the water to flow away from the other half, draining the water from the embankment, putting down the pipes, and building the other half of the embankment to a large pond converted from a low-lying marshland more than two miles away on the south bank. In order to prevent rainwater from entering, a long shed is also covered. A lot of money was spent, and the people on the south bank suddenly believed and doubted, and if it really happened, there would be enough farm fertilizer in the future, watering vegetables, planting crops, and cultivating fruit trees and mulberry forests, but whether it could be done or not, no one had a bottom.

When Boss Hu saw Song Jiu coming over, he greeted him excitedly and said, "Xiao Jiu, you're finally back." ”

"Well, I've been bothering you for the past few months."

"What's the trouble, how about going south?"

"It's fine."

"Xiao Jiu, you are a capable person in our river."

"Where, Hu Xingtou, there will be a lot of people in the river in the future."

"Xiao Jiu, I also want to read, you let me read, but I can't read it."

"If you can't read it, don't read it, just know a few words, you tell the villagers, I will pay the rest of my salary in a few days."

"Needless to say, the villagers are very relieved."

"Hu Xingtou, there is one more thing you can tell me for me, the eldest sister made a peace club, she was fooled, I asked her to disband, and you also notified everyone for me, that is a deceptive method."

"That Heian Society, I've heard some of it, too. Xiao Jiu, it doesn't matter, anyway, you have to put on incense, and it's not a bad thing to worship the gods. ”

"You don't need to form an association to worship gods."

"Okay, I'll take the time to inform the folks later." Boss Hu obviously didn't take it seriously.

Song Jiu chatted again, and when he saw that it was getting dark, he asked Boss Hu to tell everyone to go back and rest, and he was also going to go to the seventh sister's house to have a look. Just as he was about to go back, a yellow gate came over and said to Song Jiu: "Cheng Shilang, Your Majesty has summoned you into the palace." ”

"It's so late."

"It's your honor to summon you, what else is sooner or later?"

The third watch called you in the middle of the night, you have to go too, what does it have to do with the honor!
