Hand over the jade seal first [Infrastructure]

Zhai Ling was directly confused by these eight big characters, turned his head to look at Xiao Zirong and asked, "Your Highness... this... what does this mean?"

Xiao Zirong said earnestly: "I just want to remind you that when you encounter incomprehensible things, don't interpret them from the perspective of mythology, but think about conquering them and solving puzzles. Maybe you won't be able to solve them for a while, but there will always be problems." One day you will understand."

The most important thing is that he has a library with him. As long as these people have doubts, he can always find a way to solve them.

Zhai Ling and the others looked blank: "Isn't this what it should be?"

The education these people receive is like this, maybe the teacher who taught them didn't think so, but Xiao Zirong wrote the textbook for him at the beginning, and stipulated that he could only teach like this after death, so everyone is quite acceptable to these eight characters .

Xiao Zirong said tiredly, "You don't understand."

Now he can only count on the comfort of the people he brought out.

People's Wisdom...Even in later generations, cults have emerged one after another, let alone now, it is estimated that he will not be able to dispel those rumors in a short time.

After hearing this, Zhai Ling said firmly: "Don't worry, Your Highness, we will take science as our mission and will never be overwhelmed by myths and superstitions."

Xiao Zirong nodded with great satisfaction: "That's fine, come and see the new things you are about to make."

As he spoke, he asked someone to move a wooden board with his drawings sandwiched between them.

The above is the complete form of the train, not only the train but also the state of the high-speed train in later generations.

He originally wanted to do it bit by bit and make it look like a green leather train, but the front of the high-speed train is made into a bullet shape to better reduce wind resistance.

The high-speed trains are developed to that level step by step, but since Xiao Zirong has already seen it, it is better to complete it in one step.

Although the current speed may not need to consider wind resistance, it is better to make it first than to improve it later.

After Zhai Ling saw this picture, he immediately took two steps back and said vigilantly, "What is this? A snake?"

Xiao Zirong was slightly taken aback, and turned to look at the picture. Although he didn't think there was any similarity to the snake, it was because he could distinguish the snake from the train very well. In the eyes of people who have never seen a train, maybe this It does look like a snake.

Xiao Zirong clicked on the blueprint and said, "No, this is the latest means of transportation I'm researching - a steam train, which can also be called a train."

After Zhai Ling heard that it was a means of transportation, he asked curiously, "Car? What do you use to pull it? Didn't you see any horses or cows?"

Xiao Zirong laughed and said, "We don't use livestock as power, but steam engines."

"Steam engine?" Zhai Ling cheered up: "Is this what we're going to do next?"

Not to mention, this little girl still has a strong ability to grasp key points. He nodded and said, "Yes, the principle of a steam engine is very simple. When you boil water at home, you should have encountered that the steam formed by the boiled water will turn the lid of the pot. Open it, the steam engine uses this as power."

Zhai Ling thought about the kettle at home for a while, and it was a bit difficult to understand: "That motivation... is it really enough?"

"Enough fuel is enough, and the composition of a steam engine is different from that of a kettle. It is necessary to convert steam into mechanical energy through science."

Zhai Ling nodded earnestly, feeling that their city lord seems to be emphasizing science recently, and he wonders if it is because the development of science in Jinling is not going well.

Xiao Zirong removed the schematic diagram of the steam train, and the following is the exploded view of the steam engine.

He nodded and said, "Look for yourself first, and then ask me if there is anything you don't understand."

The structure of the steam engine is very simple, and there is not much physical knowledge involved.

The steam engine consists of two parts, one is the main body of the steam engine, and the other is the boiler.

The setting of the boiler is also very complicated, including the fire box, the pot body and the smoke box.

The firebox is very simple, it is the place where the fuel is burned, and the pot body is the place where the water is stored. However, the pot body will also have many smoke pipes to guide the smoke from burning coal, and just use the heat of the smoke to heat the water. It is to increase the evaporation rate and save energy on the other hand.

The smoke is then expelled through the smoke box, which also has a fan to assist with the extraction.

The steam engine is the most important part, or the steam engine plus the walking part of the steam locomotive is the most important part.

It is not the most difficult thing to make these things here. After all, Xiao Zirong has already drawn the exploded diagram, and they just need to follow suit.

But because of the existence of high pressure, a little bit of experimentation is required from material selection to details.

First of all, in terms of material selection, the best material now is the hundred-refined steel produced by Xiao Zirong, but it is very troublesome to forge, and it takes at least half a month for a sword to take shape from ore.

Xiao Zirong wanted to promote steam locomotives. The most important parts of the interior were made of rare materials. How to promote them in the future?

He can also make iron smelting more advanced, but... let's talk about it later, Xiao Zirong doesn't want to have a side job anymore, otherwise the steam locomotive will probably become the next 20-year plan, and then when he and Xiao Xuexing are old You can sit on it.

Thinking about it like this is a bit unacceptable.

As for the materials, Xiao Zirong asked the smelter to send a batch of various alloys.

Among them, the proportion of steel in the alloy is not very high, in order to make the whole metal more flexible.

Xiao Zirong led the people to build the firebox and boiler bit by bit.

Because he came every day, Zhai Ling was also very nervous, and couldn't help saying: "Your Highness, we can do this well, don't worry."

She could feel that Xiao Zirong attached great importance to steam locomotives, but he didn't look at the things he valued every day before. Could it be because he didn't trust her enough?

Xiao Zirong glanced at her and said: "Don't think too much, I'll give it away after I finish it. It's impossible to make such a big thing by myself, but at least I have participated in it."

In Xiao Zirong's view, it's one thing to give a gift whether it's precious or not, and it's another thing to use it carefully.

It is certain that gifts from their class are precious to each other, and there is no way to measure anything from the value, so they can only use their hearts.

Moreover, Xiao Zirong has always insisted on participating in the things given to Xiao Xuexing, even if they are not all made by himself.

After hearing this, Zhai Ling was really relieved, thinking that Xiao Zirong was dissatisfied with their efficiency and work quality, but... now they seem to have no quality at all.

After all, they are doing knocking and beating every day, but how can these people know this.

At the beginning, Xiao Zirong expressed his confidence that he would come. After all, he was the only one with blacksmithing experience among all the people—he was the one who forged the first hundred-refined steel sword, at least he was experienced.

However, what he didn't expect was that he didn't need to save strength when he forged steel, or he had to worry about not having enough strength when forging, and he didn't need to have equal strength for every stroke when forging.

Of course, it would be better if the strength could be controlled, but there is no problem if the control is not good. Anyway, in the end, it is enough to forge the steel until the weight of the steel is no longer reduced.

But what they are building now are fireboxes and boilers. At least from an aesthetic point of view, it is best to maintain a uniform force when beating, otherwise... it will be like the alloy Xiao Zirong is holding now, with pits and holes, let alone Looks good, and it's a long way from the minimum requirement of a smooth surface.

Xiao Zirong was exhausted, looking at this square piece of metal with a length and width of about one meter, he was very grateful for his foresight.

He originally thought that he hadn't swung a hammer for a long time and needed some time to get used to it, so this piece of metal was for him to warm up his hands.

Now the situation is that the muscles in his hands and arms are very hot, but the results are blinding.

He looked up to the side, and found that Zhai Ling and the others were also trying hard to swing the hammer, but the effect... seemed not as good as his.

There are some strong men who don't know what to do, but every time they hit the same place, as time goes by... that place is directly leaked by the hammer.

For a moment, Xiao Zirong didn't know whether to praise this person, after all, it would be very difficult to achieve such accuracy even in specialized training, but their laboratory doesn't need such an accuracy.

After two days of torture, Zhai Ling looked at Xiao Zirong dispiritedly and said, "Your Highness, if this continues, we may not have enough time."

Xiao Zirong looked at each metal plate with craters like the surface of the moon, and said in a deep voice: "I'll send someone to find some craftsmen."

He looked at everyone's dejected look, and felt that his laboratory might be disbanded if it went on like this. Although it would be impossible for him to disband if he didn't say this, the problem was that it would easily affect efficiency.

So he encouraged everyone and said: "Don't be too discouraged, you don't have this in your courses. This time, you are just familiarizing yourself with the ductility of metals. Well, it shouldn't be mentioned in this class, right?"

Zhai Ling's eyes widened: "The ductility of metal?"

Seeing that everyone was looking at him curiously, Xiao Zirong directly brought some metals over on the spot and said: "The so-called ductility of metals is the degree of softness and hardness we usually talk about. Generally, metals are too soft to be shaped easily, and too hard are too strong." It is too rigid and easy to break, so it needs to be neutralized, iron is hard enough, and copper is soft enough, plus other metals such as tin can well meet our needs."

Xiao Zirong used these metals to explain the situation of alloys. These things must not have been written in the nine-year compulsory textbooks. After all, compulsory education teaches the basics.

Seeing that everyone was listening seriously, Xiao Zirong finally breathed a sigh of relief, as long as he can divert their attention away, he will destroy the alloy he made later, such a shameful thing cannot be left behind!

When he finished speaking, Chai Shuren came over, so Xiao Zirong asked him to find some reliable craftsmen to help forging, and asked him to keep his mouth shut and not leak any news.

Tears filled Chai Shuren's eyes when he heard it. His Highness finally stopped making irons himself.

He couldn't describe the first time he saw Xiao Zirong wearing a special clothes and wielding a hammer. It can be said that his three views collapsed so badly.

Chai Shuren hurriedly helped find someone, but at this time Xie Lianyun came over and said hesitantly: "Your Highness, there have been some new rumors about you recently."

Xiao Zirong was already very calm: "Tell me, what kind of fairy am I again this time?"

Xie Lianyun said softly: "It's either a god or your favorite weapon is a hammer. You always carry it when you go to court. If there are officials who fail to do well or make you angry, you can swing the hammer at them."

Xiao Zirong:? ? ? ?

Who the hell leaked the news?

No wonder everyone in Shangchao has behaved like a quail in the past two days. Is this the reason for the co-authorship?
