Early in the morning, Jiang Tian was woken up by a crow preparing to overwinter, and his shaking head opened his eyes, only to see himself lying in the bedroom. His last memory is still stuck in the drinking session with Liu Junding yesterday, and he can't remember the rest of the matter at all. Lifted up the quilt and sat up straight, only to see that he had changed into pajamas. The feeling of thirst made him stand up with his swollen head to look for the teapot, only to find a tin wine pot on the table out of the blue. Jiang Tian thought about it for a long time and didn't know why it became like this, how did he come back, and how did he lie in bed?

After hearing the movement, Qingshuang, who was resting in the outhouse, quickly got up, put on a small coat and hurriedly walked to the inner room, and after seeing Jiang Tian, he asked, "The master got up, but he was thirsty?" ”

Jiang Tian was a little stunned, his suite used to be an exclusive courtyard for VIP guests, so it looked like a large family's bedroom. There is also a room for the maid to rest outside the master bedroom, so that he can serve the master in time. But Jiang Tian has never had a personal ring, and even if there is, Xi Yun occasionally makes a cameo, and he will never let that girl live in the outhouse.

"You ......" Seeing Qingshuang, who was only wearing a small coat, busy pouring tea for herself, Jiang Tian didn't know how to speak: "On such a cold day, do you sleep outside?" ”

Hearing him ask, Qingshuang, who brought a cup of herbal tea, paused, and straightened the hair on his forehead with his hand: "The master came back late last night, and he was a little drunk, and he was afraid that no one would take care of him late at night, and the slave family would stay outside." ”

Jiang Tian raised his head and drank the tea dry, and then apologized a little embarrassedly: "There is Miss Lao, I have no interest in you and you haven't been able to rest well." ”

"What is the master talking about, it is the duty of a slave to serve you. It's just that I'm clumsy and afraid of not serving properly......"

Jiang Tian had a bad premonition in his heart when he saw her squirming appearance, and then he remembered the crux of the problem: "I don't remember the process of going home last night, who helped change this nightgown?" ”

In fact, the answer is obvious, there are many women in the house who have other thoughts about Jiang Tian, but only the Qingyou sisters are people who have had skin to skin with him, and Xinyue and others who have not experienced men and women are naturally embarrassed to strip a man naked, and the only one who does this kind of work can only be the person in front of him.

After getting the answer, Jiang Tian was a little embarrassed, such a big person actually let people see this kind of embarrassing shape, don't look at the two sides have also experienced a lot of clouds and rain, but at that time, Jiang Tian was just a reaction under the effect of medicine, and the other party also served him out of a professional relationship, not a matter of mutual affection, so Jiang Tian still felt that this Qingshuang had nothing to do with him in his heart. There is another question in his heart, that is, why the two sisters, who have always been inseparable, have disappeared.

He soon knew the answer, and saw a sleepy-eyed girl who was also wearing only a small dress standing in front of the door, one hand still rubbing her eyes lazily: "Master is up...... Why didn't my sister call me? ”

Looking at her like that, she really didn't have the consciousness of being a maid, and even Jiang Tian couldn't help laughing: "Yesterday, there were two girls in Lao, and I was ashamed to be tight." ”

Qingshuang hadn't spoken yet, and Youlan suddenly came to her senses as if she had been stimulant: "What girl, girl, don't see you like this, I just don't know why you are holding on to this wine jug, it took me and my sister to wipe your body for a long time!" ”

Yes, Jiang Tian was even more embarrassed at this time, his feelings were not only as simple as being stripped naked, in order to hide his embarrassment, he had to pick up the wine jug on the table and look at it, and after looking at it for a while, he remembered why he was holding it.

After breakfast, Jiang Tian could clearly feel the status of the quiet sisters among the women, there was an invisible change, this is a feeling that can only be understood and cannot be described, it seems as if in this family is second only to Xi Yun and Xinyue, and has become a storage zài above other women. Of course, Jiang Tian didn't dare to throw this topic out, especially now that someone is going to talk to him, don't look at letting himself hide yesterday, this will only make people with intentions step up the pace of proposing. Jiang Tian thought very clearly about this, he was unlikely to accept a wife who was married to him, especially those daughters in traditional society, maybe they were all virtuous and gentle, but in the concept of modern people, there are no illusions about this kind of marriage without feelings. So what about picking one of the existing ones? This seems to be a good way to block the mouths of the people, but the society will not regard a good prostitute as a wife, don't look at an emperor as an example, but that is only a special case, and the mainstream social thought is not yet acceptable. Besides, it is very common to have three wives and four concubines in these years, and those in high positions will be looked down upon if they do not have a few wives and concubines. Jiang Tian didn't care about other people's eyes, but when he thought of a group of women calculating all day long in order to compete for the wind and be jealous, he had an indescribable feeling of boredom. Now that the relationship has not yet been established, these people in the family are already restless, if they are really included in the house, wouldn't it be ......

Jiang Tian shook his head, trying not to think about these things, after coming to the Academy of Sciences, he did not go directly to the classroom, but first found Song Yingxing, who had also just gone to work: "The dean is so old and diligent, my generation is ashamed of himself." ”

Old man Song, who has always been a model of attendance, ignored this ** fart, and at this age, he would not be dazzled by such childish praise: "Lord Jiang has nothing to do but go to the Three Treasures Palace, right?" ”

"Exactly!" Jiang Tian was not hypocritical, and directly took out the wine jug: "This is a tin pot, which is the top grade in the tin, but this thing is not pure tin!" ”

Of course, Old Man Song knew what this thing was, and Daokou tin ware was also a well-known trademark: "Lord Jiang has something to say!" ”

"And look at the word copper on this pot, which means that there is a small amount of copper mixed in the tin, so it can be durable for a long time, and I think adults understand the reason!"

Song Yingxing thought for a while: "You mean to mix copper in the lead word!" ”

"No, there should be something better!" Jiang Tian replied to him confidently.

In fact, Jiang Tian was only because of alcohol, after seeing the word "point copper", he recalled that he had heard the teacher in the classroom in his last life, saying that their students enjoyed the benefits brought by high technology, and that the copying, printing and other equipment were readily available and cheap to use...... Jiang Tian wondered why he hadn't remembered it before, obviously the teacher had revealed the general formula of lead movable type when he complained, and it may have been buried in the deepest part of his memory for a long time. But this raises the question of the kind of metal that needs to be mixed with lead, which has not yet been discovered on this plane!

In this way, Jiang Tian's name was not included in the alloy test working group approved by His Majesty, so Old Man Song added it with a stroke of his pen, and he also had the right to give priority to the test. However, no one was dissatisfied with this, they all knew that Jiang Tian was not only excellent in the background, but also belonged to the kind of cattle who knew more science than them when they fell asleep. It is better to have such an expert to lead the team than to make it yourself. As a result, Jiang Tian had to train physics teachers and give lessons to students in the morning, and in the afternoon he had to find what he wanted from the ore screened from all over the country.

"Sir, please see, this is a sample sent from different mines, all of them are fine tin ......" Song Yi happily asked people to move boxes of metal into Jiang Tian's office, he knew that it would be a rare learning opportunity to help Jiang Tian.

But Jiang Tian looked at the pieces of tin ingots and sighed: "Pure metal is the same thing no matter where it comes from, it seems that you still don't understand the most basic metal knowledge." ”

Next, Jiang Tian had to gather all the people involved in the test and explain to them the basics of metal. These people, including Song Yi, all of them seemed to be listening to the book of heaven, they didn't realize that the so-called metal is just a single element of the earth, and the ore is actually a natural alloy, but in order to make them available, human beings need to carry out various smelting activities, just take the most common steel as an example, simply put, it depends on the amount of carbon contained in pure iron to distinguish the properties, the more carbon is pig iron, the least carbon is wrought iron, and between the two is steel. As for bronze is an alloy of copper and tin, brass is an alloy of copper and zinc, and cupro......

"First...... Mr! Do you even know how cupronickel is refined? The book "Heavenly Creations" by Lord Song once stated that arsenic was used to point red copper to obtain white copper, but it is not known how to refine it! One of the researchers' mouths opened in surprise.

It's no wonder he was so shocked, in this era, except for people who are obsessed with science like Old Man Song, few people think about how the things used in life are made, especially the scholars who denounce labor as inferior, so when the emperor wants to establish an academy of sciences, ordinary people are not willing to come here to work, even people like Song Yingxing only know a little about science. In addition, the by-products of this alchemy are sometimes often used to pass off as silver, and it is a strictly confidential industry secret, and according to the development of history, although arsenic white copper is a unique metallurgical technology in China, it is not too widely spread because arsenic is volatile and toxic in the air. On the contrary, Yunnan's nickel and white copper was once sold all over the world and earned a lot of foreign exchange for the Qing government, until it was successfully copied by the Germans in 1823 and began industrial production, and then gradually faded out of the world stage. In this era, the forbidden and durable white copper ware is still a luxury that the rich and noble can rarely afford, and it is also an important product of the Chinese Dynasty's exports.

"It's very simple, the ore there contains some ingredients that you don't know yet, that is to say, it is a special alloy after refining, but because the content of that mysterious substance is not too high, you can vaguely see the yellow ...... of copper."

What is that substance? Quite simply, it's nickel, the vitamin of metal! It is also an additive to materials such as stainless steel. However, for this time and space, nickel is still in the category to be discovered, and it is also left blank in the periodic table compiled by Jiang Tian. This does not prevent Jiang Tian from instilling common sense in metallurgy in these future senior researchers, because some of these guys still can't figure out the difference between alloy and alchemy, but this is also determined by national conditions, Taoists have obviously studied many metal compounds in the process of alchemy for thousands of years, but few can be generalized to life examples, except for gunpowder, I have not seen their research results can affect the world. In fact, whether it is Chinese alchemy or European alchemy, their essence is a primitive chemical experiment, but we want to get the golden pill of immortality, and the other party hopes to make lead into gold, so before the development of modern science, they are destined not to have a more positive impact on society, except for the example of gunpowder being used in the military, Western alchemy is probably most proud of finding out the formula of porcelain.

The two groups of people who were completely unprofessional, both historically considered madmen and liars who did not make great contributions, had very different trajectories, and in the end they were both replaced by modern chemistry. And in this time and space, I am afraid that their fate will be doomed to be swept into the garbage heap from the day Jiang Tian became the vice president of the Academy of Sciences. This sentence is not a joke, although there is now a germ of chemistry in Europe, it is impossible to compete with Jiang Tian, who even copied the periodic table. What's more, what European prince would sit in class and listen intently to a chemistry lesson? Jiang Tian had already seen Zhang Huan mixed in the researchers, this kid relied on his cousin Wu Yuan's support, almost sideways in the Academy of Sciences, where there was a bustle you could see his figure, I didn't hear that Jiang Tian was training the researchers of the metallurgical specialty, so he squeezed in early to listen to the lecture, fortunately, this kid still knew that this was not a class, and he couldn't bear to raise his hand to ask questions.

But when it came to the fact that there were so many ways to just copper alloys, the kid finally couldn't help it: "Sir, with all due respect, do you want to find out how many new metals you can get when you mention the alloy test?" ”

Jiang Tian nodded: "Just the alloy of iron and carbon, we can get at least three materials, each of which has its own use, and in the future, we will find more new metal materials, which will create more excellent weapons, tools, durable household goods, best-selling goods, and some things that we can't imagine now, with these will not only make the life of the people of the world better, but also enable us to obtain war capabilities far beyond the enemy, and defend the security and wealth of the country, so for the sake of the great cause of the future, At present, such experiments must be carried out regardless of the cost, so as to accumulate a technical reserve that will always lead the world for future generations! ”

In the twentieth century, any Chinese would sympathize with the expression, but in this time and space, except for a few people who are thoughtful, most do not care, China has been leading the world for too long, although the recent overseas barbarians are a bit side by side, but we are not bad, especially since the emperor Xià has taken control of Jiangnan in the past few years, there are countless things with all kinds of tricks, some of them are full of praise, and they are not as alarmist as he said. Jiang Tian has no intention of analyzing the shape of the world with them, nor does he have the time to systematically explain the context of the development of science and technology with them, anyway, the holy purpose is here, you understand to implement, if you don't understand, you must implement, for Jiang Tian instead of talking nonsense with them, it is better to deepen understanding in practice.

"This time, we need to figure out the formula of lead type, because pure lead is too soft to be used for a long time, so it must be mixed with some other metals to make it strong. Just like copper, it is only after it becomes brass that movable type can be made, which is a truth. However, there is a shortage of copper in our country, and the use of copper characters is really incompatible with national conditions, so it is imperative to develop this lead character......"

Then Jiang Tian began to introduce his research opinions, in general, it is to spin on some metals similar to lead, such as tin is one of them, but Jiang Tian just didn't say the correct answer, just because he knew that the process of discovery was actually the process of learning, and the Chinese science and technology tree had him without worrying about going astray, so it was more important to properly exercise the team than to upgrade it crazily, and lay a solid foundation to accumulate thick and thin, even if he Jiang Tian was not there, he could also develop step by step. As long as you find the right direction and method, you don't have to worry about wasting time. Besides, there's a lot of metal that looks like lead, enough for these guys to practice.

After assigning the research task, Jiang Tian left Song Yi alone: "Dexin, do you have the eyebrows of those teaching aids I ordered last time?" ”

Song Yi frowned when he heard this: "Sir, it's not that the students don't do their best, it's just that the ones you want really make those craftsmen struggling." So far, there haven't been many finished products. ”

Jiang Tian thought to himself, it was just something that was very common in later generations, but it was so difficult to put it in this time and space, and the generation gap of the times really could not be solved by one or two technological leaps: "Then I don't know how much time it will take in the end?" ”

"This ...... The students were not sure, so they had to take their time. ”

was about to go out, but Zhang Huan, who hadn't left yet, happened to hear their conversation, but he didn't make a noise but secretly wrote down the incident. Jiang Tian had no choice but to ask Song Yi to send some things that were not too difficult to make to his home first, and he couldn't say that he wanted to enroll students, but the school ended up not starting for a long time, isn't that the same as some pheasant universities? It's just that none of them expected that from today, a national-level experiment that has been carried out intermittently for nearly a hundred years will be officially launched, and it will become the main work of the Institute of Metallurgical Science under the Royal Academy of Sciences. It is not clear how much resources are spent, but the impact is all over the world, and some Western commentators have said: We cannot surpass China, not only do we not have a far-reaching scientific giant, and an emperor who understands science. And because no country in the whole of Europa can put so much money and scientists into such a long experiment, even if it gathers the power of all Europe!
