Although their major is industrial design, they need to understand the properties of materials when designing, and they also have some understanding and dabbling in the raw materials of the things they have designed. And because of the attributes of the top students, their research on raw materials will not just stay on the surface.

The two have different genders, different personalities, different things they are interested in, and different aspects they are involved in. Or the same thing, the point, depth and breadth of understanding between the two are not the same.

In this way, it is not difficult for two stinkers to get together, and then use these skilled craftsmen in ancient times to put into experiments, and want to have a small-scale industrial revolution in Dajin.

Hearing Xiao Lingyan say this, Zhao Ruxi nodded: "Alloy spring steel is mainly silicon-manganese steel, with a slightly lower carbon content, mainly by increasing the content of silicon to improve performance, I don't know these ratios very well, if you have resources in your hands, you can call the smelting craftsmen of the Ministry of Industry to give it a try." ”

She racked her brains to recall her knowledge of steel smelting: "In addition, there are alloy spring steels of squeo, tungsten and vanadium, and boron, niobium, molybdenum and other elements can be added to the basis of silicon-manganese steel......

As a boy, Xiao Lingyan is naturally more interested in girls in this regard. He knows what Zhao Ruxi said.

"Don't worry, I know it. It shouldn't be long before I can get them to smelt new steel. I have to rely on them for the wires and bearings of my vehicle. He said.

Speaking of this, Zhao Ruxi asked: "Is there any rubber?" ”

Xiao Lingyan shook his head: "I can only let people pick eucommia gum." This one is not in a hurry, it will take time. Just give it to me. ”

He looked at Zhao Ruxi: "You need a spring, what do you want to do?" ”

"I want to make mechanical clocks." Zhao Ruxi said.

She definitely can't do a delicate machine like a watch, but she thinks it's still feasible for a craftsman to make a handmade grandfather clock and spend a lot of effort to make one or two first.

Xiao Lingyan's eyes suddenly lit up, and he patted the armrest and said, "That's a good idea." ”

Both he and Zhao Ruxi have gone to Germany with their mentors to do projects. He spent five months in Germany; Zhao Ruxi stayed there for a whole year.

People like them, who do mechanical design, can't help but study machinery when they encounter it. German watchmaking was so delicate that they both studied it.

Zhao Ruxi said: "Actually, I originally wanted to do printing. The spiral prototype wooden printing press invented in Europe in the middle of the fifteenth century did not use steel at all, so I drew a drawing, called a few carpenters, and it didn't take long to make a printing press. ”

Xiao Lingyan nodded: "This is completely fine." I remember you and your mentor designing a new type of printing press. ”

As long as they know the principle of the printing press, and then visit this old wooden printing press, it is completely possible to copy it and improve it, and the lead type is no problem for them.

"I had this idea when I accompanied Xu Xue to the bookstore to sell books. After this thing is made, it can at least reduce the cost of reading and increase the literacy popularization rate of Dajin. Zhao Ruxi sighed, "But once this thing is made, the impact on the printing workshop and bookstore will be too great." And the money you make is not much, and it belongs to the long-term flow type. Pull the hatred value is top-notch. The disadvantages are small and not cost-effective. So after thinking about it, I gave up. ”

Xiao Lingyan's brows furrowed.

Knowledge is often in the hands of the ruling class. Large printing workshops and bookstores are no exception to the means of disseminating knowledge. The big printing workshops and big bookstores in these places in Beijing and Bac Ninh were opened by various families. The same is true elsewhere.

Once the printing press is made and the cost of printing is reduced, the price of books will definitely be much cheaper, and the number of people who can afford to read will increase accordingly. Although this has benefited many scholars and ordinary people, and is beneficial to the entire Great Jin Dynasty in the long run, it is undeniable that it will definitely violate the interests of the family that opened the printing workshop and the bookstore in the short term.

Historically, many changes have failed because they violated the interests of rulers and large landowners. With him, although he can protect Zhao Ruxi, it is completely unnecessary to stand on the opposite side of the family before the upcoming two political struggles, just to fight for a little monetary benefit.

"You're right. This thing can be done, but not now. ...... future," he glanced at Zhao Ruxi meaningfully, "The days to come will still be long, take your time, don't worry." ”

Zhao Ruxi waved his hand: "This not only violates the interests of the family, but also makes many people who make a living from it have nothing to eat, such as scholars who make a living by copying books, craftsmen in the printing workshop, and some small owners and men who open bookstores." The production of machinery frees up labor, in fact, it makes people in this industry unemployed. This kind of thing is a bit detrimental to yin morality, so let's take it easy. ”

Any industrial revolution inevitably brings unemployment among workers.

If someone makes a fuss about this and encourages those workshop workers to come to her to make trouble, even if she is protected by her master and brother outside, and Xiao Lingyan helps inside, she will have to make a fuss.

Anyway, it's not cost-effective to do it now, and it's too much trouble.

"I thought about it and thought that I would just make the money of the rich. Make a few big grandfather clocks, send one to the emperor, and sell a few more sky-high prices, this money comes quickly, and the money is still made by rich people, don't be too cool. After half a year and a year, we will re-launch a more exquisite and accurate clock, and re-propose a high price. ”

"Yes." Xiao Lingyan stroked his palm, "Actually, printing can also take such a path there." Let's get the printing machine out and sell it. When you make a sum of money, you can improve the machine and reharvest the money of these families. ”

"Xiao Ke." Zhao Ruxi tapped him with his finger, "I found you really bad." ”

"Each other, each other."

The two of them looked at each other and laughed "haha".

"Let's start with these three projects. I'll do the rest when I have a chance. Zhao Ruxi said, and asked Xiao Lingyan again, "Did you send someone to the matter of Jade?" ”

"After telling you that day, my men set off the next day. I set up a contact point along the way, and when I got the result, I would fly the pigeon and come back. He asked, "You bought people, didn't you?" How's the training? After I find the jade here, can your people send it to buy and transport it? ”

Zhao Ruxi nodded: "I feel that it should be possible." ”

Let Zhou Chun and Ma Sheng bring some people there, she feels that it is still okay. Both of these seem to be capable well.

The value of jadeite has not yet been discovered, and in the eyes of others, this thing is just stone. Transporting the stones back from the south is not very risky, and Zhou Chun and Ma Sheng should be able to do it.
