The bridge was not built, and if you want to get to the other side, you either have to take a detour or ferry, and a few people ferry over, because they want to transport materials, and many boats are parked on the unformed wharf of the river island at this time.

Zhao Kuangyi and Lu Duan took Han Chongyun and Song Jiu, as well as a cadre of officials, on the boat.

There are craftsmen in command, and when building the blast furnace, the reinforced concrete was pierced once, as long as Song Jiu occasionally supervised, the problem would not be too big. Zhao Kuangyi's eyes still flashed with a trace of worry. Song Jiu said, "Second king, please rest assured. ”

On both sides of the river, the principle of force on the bridge was introduced, and he said: "The reason why the span can be extended is that the reinforced concrete integrates the bridge. The original masonry glutinous rice flour bridge is difficult to do, so it can not be a flying bridge, but only a plane bridge, and the span does not dare to be expanded. But the span has reached a certain point, and even the reinforced concrete will produce torsion, but there are twelve cables to 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. Just a little. ”

"What?"

"The exposed steel is easy to rust, although Weichen has prepared a second place to replace the steel cable, which can be replaced once every few decades to ensure that the bridge will stand safely for hundreds of years, but this rust is a headache. And the current resin paint can't play a role in rust prevention, and there are follow-ups. ”

"Is there a way to fix it?"

"Second king, this bridge was painted last year, can't Weichen think of it? There is a way to solve it, and you can see it when I go to that testing laboratory. ”

Is there a way, like this mechanical principle, for Zhao Kuangyi, it is all strange.

This is not a mental technique, not a power scheme, not what Zhao Kuangyi is good at.

On Hezhou, Han Chongyun suddenly asked, "Jiulang, Han heard that you want to destroy the Dao?" ”

Song Jiu almost fell down, where he stood stunned, "General Han, who did you listen to, what kind of courage do I have to destroy the Dao?" ”

"The Buddha must not be unbelieving, Sejong destroyed the Buddha and died young, just like we have killed countless people in our lives, and sometimes we often have nightmares at night. Therefore, General Shi believes in Buddhism, and General Li also believes in Buddhism, and I also believe in it a little, at least it will make me feel at ease. ”

Song Jiu was silent.

The Song Dynasty was able to stand, not only Zhao Kuangyin, but also the merits of these generals. Zhao Kuangyin for the stability of the country, coupled with the idea of Zhao Pu, an important formulator of the national policy, he was born as a official, one is an official, the other is a general, and the two positions are different, so one monarch and one minister began to deprive the military generals of their rights. I can't say it's wrong, but it's done a little too much, and the Song Dynasty can be said to be eating the old book, eating the old book left by Chai Rong! After eating this generation's old book, the next generation will be sad.

After a long time, Song Jiucai said: "General Han, I don't reject the Buddha's interpretation, let alone the right to reject the Buddha's interpretation, but I don't think it's good for someone to use religion to form an association." ”

Song Jiu didn't say deeply, Zhang Long'er was just a god stick, not Zhang Jiao, and there were no organizations such as the White Lotus Sect in the Song Dynasty, so he didn't have a strong sense of religious prevention, and even intended to support it. said too much, it was also the eldest sister who did not do well, she was not fooled, did Zhang Long'er force the eldest sister to take out the money with a knife, and organize the people to put the money in his pocket for him?

I don't know that the person in Lu Dao also told Han Chongyun to listen, so he would have this question. He added, "Whether it is the death of Sejong or the death of his father, it is not that he has killed too many enemies, but that there is something else in the laboratory. ”

All in those dozen or so new houses.

Liuli research is in the back yard, there are many people, and Song Jiu sent people to build a wall in the middle to separate it. There were many micas in the courtyard, and Song Jiu pointed at them and said with a smile: "Some time ago, I asked the imperial court to send officials from all over the country to send people to find mica-shaped flake ore, and as a result, a lot of mica was sent from all over the country. ”

Mica also has a role now, when the medicine, it is said that mica has the effect of building to remove wind evil, enrich the five organs, increase fertility, make the eyes bright, take the body for a long time and be light and dexterous, and prolong the life.

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

"I'm looking for an ore that has a mica-like texture, but doesn't contain mica at all, and its real name should be mica iron oxide, and it should be found in many places. As long as it is found, a new lacquer can be researched to prevent rust on the iron. At present, the effect will not be too big, whether it is weapons or agricultural tools or kitchen utensils, they will not be painted, at most they will be oiled and rust-proof. However, in the future, iron production will increase, and there will be more and more uses, and this lacquer will become important. And every kind of mineral deposit comes in handy, which will bring more life to the people. ”

"Song Jiu, it's difficult."

"Second king, why is it difficult?"

"Song Jiu, do you know how much Lu Dao has worn out for this iron official?"

"I don't know how to do it, by the way, the second king, if the gunpowder is used, how much iron can I add in a year?"

"It's better than what you said, and it's higher than what the official thinks, but Hunan is asking for iron, and the armor and weapons of the front-line soldiers are also iron, so isn't that more important than you?"

"But ......"

"I know that it was the official who promised you at that time, so the problem was the turn of the official, and because of the transfer back to the iron pit system of the Tang Dynasty, some very bad things happened, and besides, where are there so many criminals in the country? Many criminals are not guilty of capital crimes, and they become mining slaves, and they are more auspicious than ......"

"Second king, simply turn it into a real contract, I also went down to see it, the kind of system implemented by the imperial court before was also inappropriate, it was not called contracting, but forced apportionment."

"Contracting?"

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

"What auction?"

"The officials of the states gathered together the rich families of the states and counties, told them the situation of the mines, and asked them to bid for them, and the prices they put on paper were put into the box, and the higher ones were to be paid, but no officials and nobles were allowed to enter, so as not to harm the fair bidding. As long as the mine owners do not restrict the freedom of the miners, do not abuse the miners, and run the business themselves, they will get more for their work. If the highest price is lower than the imperial court's appraisal, and someone is sent to recalculate, if it is not wrong, it means that the local wealthy merchants are greedy and insatiable, so they have to continue to operate in various states and counties. If the officials and businessmen collude, the mine owners will have more, and the other rich households will be red-eyed, and they will take the initiative to raise the price for the imperial court after five years. In this way, the imperial court does not have to worry about it, and the number of officials can be moved to reduce the burden on the imperial court. ”

There will be a lot of loopholes to drill into, but which policy comes out and can't find a loophole?

Zhao Kuangyi only asked: "What about gunpowder?" ”

"The law does not allow private sales, and gunpowder is distributed to mine owners according to the amount of iron produced by each mine. No matter how strict the legislation is, if the price is high, gunpowder may even be sold privately to foreign countries. However, under the care of the officials, those petty officials did not dare to sell privately? It is still the source that is guarded, the gunpowder formula of the capital and the gunpowder production made of gunpowder. Weichen also said that its power is not small, but when it is not really used, it cannot make various cities pose a deadly threat. Chen went to Hunan, where there are many metal deposits, once gunpowder is popularized, just mining alone will bring infinite vitality to the local area. This is its real function, for the country, for the people! If you don't want to further increase iron production, what is the idea of beating Weichen with hundreds of thousands of catties of iron? ”

"What good things did you show the officer?" Zhao Kuangyi didn't want to talk more about it, so he changed the topic.

"Second King, you come with me," Song Jiu led them to another room, where there were two things, one was asbestos tiles and the other was linoleum. Two craftsmen are wearing masks to debug, and it is a bit unrealistic to talk about any hazards, such as salt.

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

Asbestos was also used very early, Song Jiu did not have the support of the imperial court, because the people had it, and there were not many of them, and it was used to make fireproof clothing to wear, whether it could be worn made Song Jiu very doubtful, and it seemed that the harm of wearing it was not less harmful than knocking mica stone. It has nothing to do with Song Jiu, just bought some asbestos. But if you want to mine on a large scale, you have to use gunpowder. Guarding against it like this is not a way, nor is it the result that Song Jiu wants to see. With asbestos, with fine sand and cement, asbestos tiles can be made. Maybe Zhao Kuangyi doesn't quite understand its role, but he just sees that it is very big.

Song Jiu said, "Second king, let's lift it." ”

The two of them lifted up, and Zhao Kuangyi said, "It's so light...... The officer understood why the roof of the warehouse was weird. ”

Not to mention the fire prevention function, bricks and tiles are also fireproof, but they are very heavy, one heavy means that there will be more wooden beams or steel, the emergence of asbestos tiles not only means that the construction of warehouses will save a lot of costs, but also lay the foundation for the construction of larger warehouses, and said: "Sure enough, it is a good thing." ”

Linoleum Song Jiuwei introduced, the Song Dynasty had asphalt, some shallow oil mines often spewed out oil, floating on the water, the Song Dynasty will use it to make weapons in the future. Although Song Jiu mixed asphalt with asbestos to form linoleum, the amount of asphalt was too small to meet the needs of large-scale production. So Song Jiu got it, but finally gave up although he got it. Or large-scale oil extraction, oil smelting, then it is better to let him make airplanes.

The reason why the asphalt is another role, there is no anti-rust paint for the time being, that is, to find mica iron ore, it will take a long time to become an anti-rust paint. This is to use the viscosity of the asphalt to roll together with the oil, and apply it to the steel cable to play a temporary anti-rust role.

and brought Zhao Kuangyi to the back.

It was not brought to the place where the craftsman tested the glass, but to the real test laboratory, which contained many glass tubes and 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 cleaned with it." ”

Zhao Kuangyi was about to pick it up and look at it, but Song Jiu suddenly grabbed him in front of him, grabbed his hand and said, "The second king can't do it." ”

In order to let Zhao Kuangyi understand its power, Song Jiu asked the guards to go to the front and bring a piece of mutton that the craftsman was preparing to make dinner, and poured a little liquid on it. The front is upside down, the back is full of smoke, and the lamb turns charred black. A servant nervously stopped in front of Zhao Kuangyi, but he was also trembling with fright.

"It's poisonous."

"Second king, it's not poisonous, but corrosive, it's different from poison," Song Jiu asked the guards and servants to pull out the weapon, chose a rusty Pu knife, diluted this terrible solution, put the Pu knife in it, took it out and washed it with water, wiped it with a rag, and turned it into a newly baked Pu knife.

"That's a good thing, too."

"The second king, Wechen said, a river island becomes the appearance of Wechen on the drawings, there will be a lot of good things, most countries can use it, but not now, including asbestos tiles, are all test laboratory products, asbestos tiles want to popularize mass production, there are some foundations, it is easier. Maybe when the autumn wind rises, you can get on the horse. However, this thing is about not good," Song Jiu sighed in his heart, it is the mother of industrialization, very, very important, but he doesn't know how to mass produce it, and it can't even meet the future production needs of colored glass. Moreover, the cost of this production method is also relatively high. He only said that it had one effect, and without saying more, he walked up to another bottle and said, "That's it." Why Sejong died early, because he participated in the battlefield in his early years, and there were many wounds on his body, although he bandaged the wound at that time to stop the bleeding, but left sequelae, and later the accumulated injuries occurred and died young. But as long as it is diluted, the wound is cleaned, and the wound is sterilized and disinfected, the probability of sequelae will drop by half, or even seventy percent. This alone can save the lives of hundreds of soldiers in a year. That is, with it, Sejong will not die early, and his father will not die early. ”

The actual weapon wound is best cleaned with hydrogen peroxide, but that is too impractical, purple potion is also fine, including high-concentration wine, but these two are strictly not as effective as the anti-virus effect of boric acid water. If it is combined with refined brine and high-concentration wine and boric acid water, it will theoretically indeed have the effect that Song Jiu said.

Moreover, there is a medical effect, the Song Dynasty also paid attention to hygiene, there are bathrooms in various cities, but the conditions are limited, and there are not many people who can take a bath every few days, so many people get all kinds of dermatitis rashes, and then invent a thing, tickle and pick. With it, it is possible to effectively treat all kinds of dermatitis rashes.

"That's good, too."

"It's good, but it can't be popularized, and it hasn't even been fully studied in this experiment."

Zhao Kuangyi walked a few steps, and then grinned and stared at the black mutton, the official stopped in front of him and trembled, he also trembled several times in his heart, and said, "Song Jiu, by the way, let's also build the academy." ”

Song Jiu bent down and laughed.
