Before the bridge was built, I wanted to go to the other side, either detour or ferry. A few people ferry over it. Because they wanted to transport materials, many ships stopped at the unformed dock in Hezhou at this time.

Zhao Kuangyi, Lu Duan took Han Chongyun, Song Jiu, and a group of officials on board.

There were craftsmen in charge and reinforced concrete was laid once when building the blast furnace. As long as Song Jiu supervised it occasionally, the problem would not be too big. A trace of worry flashed in Zhao Kuangyi's eyes. Song Jiu said: "Second King, please rest assured."

The principle of stress on the bridge was introduced on both sides of the river, and said: "The reason why the span can be widened is that reinforced concrete integrates the bridge into one. The original brick and stone glutinous rice flour bridge is difficult to achieve, so it cannot be a fly bridge, and it can only be a planar bridge, and the span is not dared to be widened. But the span has reached a certain point, even if the reinforced concrete will produce torque, there are twelve cables that will pull up, and there will be no more accidents. Even if you don't care about financial resources, it can be higher and the span can be larger. It's just a little bit."

"what?"

"The exposed steel is prone to rust. Although Weichen has prepared a second place to replace the steel cable, which can be replaced every decade to ensure that the bridge has been safe and stable for hundreds of years, this rust is a headache. Nowadays, the resin paint cannot prevent rust, and there are some subsequent things."

"Is there a way to solve it?"

"The second king, this bridge was painted last year. Can't I think of it? There is a way to solve it. You can see it by following me to the laboratory."

Is there any way, just like this mechanic principle, for Zhao Kuangyi, it is a strange tale in heaven.

This is not a mental skill, not a power strategy, nor is it director Zhao Kuangyi.

After getting to Hezhou, Han Chongyun suddenly asked, "Jiulang, Han heard that you want to destroy the Tao?"

Song Jiu almost threw himself down and stood there and said blankly: "General Han, who did you hear me? What courage do I have to destroy the Tao?"

"Daoshi must also believe that Emperor Shizong destroyed Buddhism and died young, just like we killed countless people in our lives, and sometimes we often have nightmares at night. Therefore, General Shi believes in Buddhism and General Li believes in Buddhism. I also believe it a little, at least it makes me feel at ease."

Song Jiu was silent.

The Song Dynasty was not only Zhao Kuangyin, but also the contribution of these military generals. In order to stabilize the country, Zhao Kuangyin, coupled with the idea of ​​Zhao Pu, the important maker of national policy, was a member of the official, one was an official and the other was a general. The two positions were different, so one monarch and one minister began to deprive the rights of the military generals. It cannot be said that it was wrong, but it was done too much. The Song Dynasty could be said to be reaping the old capital and the old capital left by Chai Rong! After eating this generation of capital, the next generation would be miserable.

After a long time, Song Jiucai said, "General Han, I don't reject Buddhist scriptures, nor do I have the right to exclude Buddhist scriptures. However, I don't think it's good if someone uses religion to form associations."

Song Jiu did not say in depth that Zhang Longer was just a charlatan, not Zhang Jiao. In addition, there was no organization like the White Lotus Sect in the Song Dynasty, so he was not aware of religious prevention and even intended to support him. If he talked too much, it was because the eldest sister did not do well and she was not deceived. Did Zhang Longer use a knife to force the eldest sister to take out the money and organize the people to put the money in his pocket for him?

I don’t know who said that person to Han Chongyun, so he would have this question. He also said: “No matter whether the death of Emperor Shizong or the death of his father, it is not that he killed too many enemies, but that there is something else in the laboratory.”

All in those dozen new houses.

Liuli Research was in the back yard, with many people and mixed hands. Song Jiu sent people to build a wall in the middle to separate it. There were many micas in the yard. Song Jiu pointed at them and said with a laugh and cry: "Some time ago, I asked the court to issue an edict from all over the country to send people to find ore in mica, but many micas were sent from all over the country."

Mica also has an effect now. As a medicine, it is said that mica has the effect of removing wind evil, enriching the five internal organs, increasing fertility, making the eyes bright, taking them for a long time, and extending life. Some people knock it, but Song Jiu dare not knock it, but the consequences are better than knocking the small balls refined by Taoist priests.

"What's the difference?" Lu Duan asked.

"What I am looking for is an ore, whose texture will appear mica-like, but it does not contain mica at all. Its real name should be mica iron oxide, and there should be its mineral deposits in many places. As long as you find it, you can develop a new paint to prevent rust on the iron. The effect will not be too great at the moment. No matter weapons, agricultural tools or kitchen utensils, it will not be painted, and at most it will be oiled to prevent rust. However, in the future, iron production will increase more and more uses, and this paint will become important. And every mineral deposit comes in handy and will bring more vitality to the people."

"Song Jiu, it's hard."

"Why is it difficult for the two kings?"

"Song Jiu, do you know how much of your mouth has been worn out for this Iron Official?"

"I don't know, by the way, the second king, if gunpowder continues to be used, how many iron can I add to my dynasty in a year?"

"It's better than what you said, and it's higher than what I thought. However, Hunan is looking for iron, and the soldiers on the front line also need iron armor and weapons. That's not more important than you?"

"but……"

"I know, I promised you at that time, so it was my turn to have a difficult problem. Because I turned back to the iron pit system of the Tang Dynasty, some very bad things happened. Besides, where are there so many criminals in the country? Many criminals are not guilty of death and become mine slaves, which is more and more likely to be lucky..."

"The second king, just turn it into a real contract. I have also gone down to see that the system implemented by the imperial court before was also inappropriate. It is not called contracting, but forcibly levying."

"contract?"

"The court first mines, then calculates based on its output and cost, and sends officials to estimate the bottom line based on these output and cost, and then auctions publicly."

“What auction?”

"Officials of each state gathered wealthy households in each state and county, told them to bid for the mines, and wrote them on paper and put them into the pot. Those with the higher prices will be paid, but no officials and nobles are allowed to enter, so as not to harm fair bidding. As long as the mine owners do not restrict the freedom of miners, do not abuse miners, and run them themselves, and they will get more work. If the highest price is lower than the valuation of the court, they will send people to recalculate it. If there is no mistake, then the local wealthy businessmen are greedy and have to continue operating in each state. Then, it is impossible for local wealthy households to form a group together. If the collusion between officials and businessmen, the miners will earn more, and other wealthy households will jealous, and they will take the initiative to raise the price for the court in five years. In this way, the court will not have to worry about it, and can also remove the number of officials and reduce the burden on the court."

There will be many loopholes to be exploited here, but if that policy comes out, no loopholes can be found?

Zhao Kuangyi only asked one question: "What should I do if gunpowder?"

"The rule of law shall not be sold privately. Gunpowder shall be distributed to mine owners based on the amount of iron produced by each mine. No matter how strict the legislation is, if the price is paid, the gunpowder may be sold privately to foreign countries. However, under the supervision of the officials, those minor officials dare not sell privately? The source is still the source, the gunpowder formula in the capital and the gunpowder made of gunpowder. Weichen also said that it is powerful, but if it is not really used well, it will not cause a fatal threat to various cities. When I went to Hunan, there are many metal minerals. Once gunpowder is popularized, it will only be mined, which will bring infinite vitality to the local area. This is its real function, used for the country and the people! If I don't find a way to further increase the iron output, what is the idea of ​​hitting Weichen's hundreds of thousands of kilograms of iron?"

"What good things do you bring to me to see?" Zhao Kuangyi didn't want to talk about it more, so he changed the topic.

"Two Kings, come with me," Song Jiu took them to another room, where there were two things, one was asbestos tiles and the other was linoleum. Two craftsmen were debugging with masks. It was a bit unrealistic to say what harm was, such as salt.

However, Song Jiu still asked the craftsmen to wear a mask and protect themselves.

Asbestos was also used very early, and Song Jiu did not have the support of the imperial court because it was available in the people and there were not many. It was used to make fireproof clothes to wear. Song Jiu was very suspicious. It seemed that the harm of wearing it was not less than that of mica stone. It had nothing to do with Song Jiu, and he just bought some asbestos. But if you want to mine it on a large scale, you still had to use gunpowder. This way of preventing and banning is not a solution, nor is it the result that Song Jiu wanted to see. With asbestos, paired with fine sand and cement, asbestos tiles can be made. Perhaps Zhao Kuangyi didn't understand its function yet, but he just saw that it was very big.

Song Jiu said, "Two kings, let's carry it."

The two of them raised up and Zhao Kuangyi said, "It's so light... I understand why the roof of that warehouse is strange."

Not to mention fireproof functions, bricks and tiles are also fireproof, but they are very heavy. Once they are heavy, it means that there will be more wooden beams or steel. The emergence of asbestos tiles not only means that building a warehouse will save a lot of costs, but also lays the foundation for building a larger warehouse, and says: "It's indeed a good thing."

Lin felt Song Jiu did not introduce that there was asphalt in the Song Dynasty. Some shallow petroleum mines often sprayed oil and floated on the water surface. The Song Dynasty would use it to make weapons later. Although Song Jiu used asphalt and asbestos to press it into linoleum, the amount of asphalt was too small to meet the needs of large-scale production. So Song Jiu did it, but even though it was done, it was finally given up. Or it was better to let him build an airplane than to mine oil on a large scale and smelter oil.

The reason why we get asphalt is another function. There is no anti-rust paint for the time being, it is because mica iron ore is found, and it will take a long time to turn it into anti-rust paint. This uses the viscosity of asphalt and oil to roll it together and apply it to the steel cable to play a temporary anti-rust effect.

He brought Zhao Kuangyi to the back.

Instead of taking it to the place where the craftsmen test the glass, they brought it to the real laboratory, where there were many glass tube bottles. Song Jiu pointed to a bottle and said, "But before oiling, even if the steel cable comes out for a day, there will be some oxidation and rust, and it must be used to clean it."

Zhao Kuangyi wanted to pick it up and see it. Song Jiu suddenly grabbed him and grabbed him with his hand and said, "The Second King is not allowed."

Nothing in this place can be moved casually. If it moves, something will happen. In order to let Zhao Kuangyi understand its power, Song Jiu asked the guards to go to the front to get a piece of mutton that the craftsman prepared for dinner, and poured a little liquid on it. Pour it in front, and the smoke from behind rose up, and the mutton turned burnt black. A yamen runner nervously stopped Zhao Kuangyi, but he was also scared and trembled.

"Very poisonous."

"The two kings, it is not poisonous, but corrosive, which is different from poisonous," Song Jiu asked the guards and the yamen runners to pull out the weapons, chose a rusty Pu Knife, diluted this terrifying solution, put the Pu Knife inside and ripped it out, washed it with clean water, wiped it, and turned it into a newly-baked Pu Knife.

"This is also a good thing."

"The two kings, Weichen said that a river in the past will look like a Weichen's drawing, and many good things will come out, which can be used by most countries, but not now. Asbestos tiles are all products of laboratory products. If asbestos tiles are popularized for mass production, they have some foundations and are easier. Maybe the autumn wind will be launched. However, this thing may not work," Song Jiu sighed in his heart. It is the mother of industrialization and is very important, but he does not know how to mass produce it, and it cannot even meet the future demand for glass production. Moreover, this production method is also relatively costly.

. He only talked about one function of it, and without saying much, he walked to another bottle and said, "It is it. Why did Shizong die early? Because he participated in the battlefield in his early years and had many injuries on his body. Although he applied medicine to bandage the wound to stop bleeding, he left behind sequelae. Later, the accumulated injuries occurred and died young. But as long as he used it to dilute, clean the wound, and sterilize the wound, the probability of sequelae would be reduced by half, or even 70%. This alone can save the lives of hundreds or thousands of soldiers in a year. That is, with it, Shizong will not die early, and his father will not die early."

In fact, it is best to clean the wounds of weapons with hydrogen peroxide, but that is too impractical. Purple potion is also good, including high-concentration wine, but these two are strictly less effective than boric acid water. If it is combined with refined salt water and boric acid water, it will theoretically have the effect that Song Jiu mentioned.

Moreover, it also has medical effects. The Song Dynasty also paid attention to hygiene. There were bathrooms in every city, but the conditions were limited, so not many people could take a bath every few days. So many people had various dermatitis rashes, and then invented something, tickling it. With it, it could effectively treat various dermatitis rashes.

"That's good too."

"It is good, but it cannot be popularized. It has not been completely studied in this experiment."

Zhao Kuangyi took a few steps, stared at the black mutton with his teeth again. The yamen runner stopped him and shivered. He also shivered in his heart several times, and said, "Song Jiu, build the academy by the way."
