Hand over the jade seal first [Infrastructure]

Xiao Xuan angrily wrote a long letter to scold Xiao Xuexing, and asked Xiao Zirong to write to him.

Xiao Xuexing was scolded a lot by him, it didn't hurt at all, so he turned to Xiao Zirong and asked, "Do you want to write a letter to His Majesty?"

Xiao Zirong looked at Xiao Xuexing's expression and asked softly, "Is it okay not to write?"

"Write if you want to, and don't if you don't want to."

Only then did Xiao Zirong breathe a sigh of relief: "I don't know what to write to him, why don't you tell him that I can't read much."

Xiao Xuexing squinted at him: "You don't know many words?"

Xiao Zirong can recognize those characters that he doesn't know without any obstacles. What kind of person doesn't know many characters?

Xiao Zirong gave him a sweet smile, saying that if you can't read, you don't have to worry about being jealous. Even if you are an emperor, an illiterate has nothing to suspect.

If he can, he is even willing to follow the example of Marquis Haihun and give him a far-off fiefdom. It doesn't matter if he is rich or not, he will always find a way out anyway.

Even... It would be nice to give him Taoyuan City as a fief. It's a little small, but he already has feelings.

Xiao Xuexing didn't say much, and simply put Xiao Xuan's letter aside.

Xiao Zirong asked curiously, "Aren't you going to reply?"

Xiao Xuexing said casually: "Don't worry, wait until His Majesty calms down."

This is the first time Xiao Zirong has seen such a method of dispelling qi. According to normal logic, shouldn't it be you who wrote a letter trying to justify and coax the emperor?

He suddenly felt a little aggrieved by his uncle being the emperor.

Seeing Xiao Zirong's expression, Xiao Xuexing knew what he was thinking and said with a smile, "Don't worry, Your Majesty has a good temper."

Xiao Zirong said in his heart that I don't think His Majesty has a good temper, probably because he has nothing to do with you.

However, Xiao Xuexing like this has the appearance of a powerful minister, who doesn't take the emperor seriously, how in line with his current personality.

If it was in the past, Xiao Zirong would definitely think that Xiao Xuexing was not a good person, but now... Xiao Xuexing loves and does what he wants. Thinking about those people in court who asked him to lead troops to fight without giving food and grass, he would hold a grudge .

Now he doesn't have the ability to trouble these people, but Xiao Xuexing probably won't suffer such a disadvantage, if Xiao Xuexing wants to deal with them, he can just help out a little later.

Xiao Xuan's letter didn't cause much splash in Taoyuan City before it was thrown behind the heads of the two brothers.

Xiao Xuexing is completely focused on his younger brother. Anyway, the sky is high and the emperor is far away, and the emperor has a lot of things to do, so let him wait for a while.

Xiao Zirong, on the other hand, was busy with other things. After tossing and tossing for a long time, he finally started to develop antibiotics.

From the simplest point of view, there are generally three extraction methods for antibiotics: the first is to extract penicillin from plants, the second is to extract penicillin from penicillium, and the third is to extract sulfonamide from stones.

At present, the probability of the first two being realized is very low, or it will take a long time to realize it, but Xiao Zirong does not dare to waste too much time now, Xiao Xuexing's body will not be able to hold it if it takes too long.

So the easiest thing is to extract sulfa from the stone.

In fact, the so-called extraction from stones is not really an experiment on stones. The main materials still need to be obtained through various methods. Among them, charcoal can obtain aniline, and in addition to aniline, chlorosulfonic acid, ammonia water, and sodium bicarbonate are also required. Synthesis with chemical substances such as acetic anhydride to get the final sulfonamide.

To be honest, even if she was a science student, Xiao Zirong felt dizzy watching this series.

But he has already taken a shortcut. After all, he has already reached a conclusion. As long as he conducts reverse derivation, he can always find a way to make something, but this process may lose a lot of hair.

After Xiao Zirong wrote down the methods needed for these things, he thought about it carefully. There are two things in it, the most important one is sulfuric acid, and the other is electricity.

Sulfuric acid can be put aside first, it's not too difficult, but electricity... people's understanding of this word is still pure lightning, and they even think that this thing is God's punishment, but they don't know that it can be used.

Xiao Zirong wants to make electricity...or rely on thunder and lightning to proceed to the next step.

However...he glanced at the time, it was winter.

There is basically no thunder in winter, and thunder in winter and snow in summer are very, very rare natural phenomena, so this step is basically stuck.

After thinking about it, he might as well make preliminary preparations first, get everything ready, and wait until spring and summer when there is a thunderstorm.

The most important part of power generation is a powerful magnet, which cannot be replaced by ordinary magnets.

However, the things that powerful magnets need the most are iron and copper wires. These two things are available, but they can be regarded as strategic materials. Xiao Zirong can only turn his head to find Xiao Xuexing.

Xiao Xuexing asked: "How much do you need, do you want it now?"

Xiao Zirong said a little more quantity in order to prepare for failure. Anyway, he has never succeeded in making something before, even if there is a whole process, he still has to prepare.

But he was not in a hurry, Xiao Xuexing made some calculations and said, "It may take a few years."

Even if he used a large amount of strategic materials, he still had to go through formal channels, or because it was him, he had to go through these formal channels.

After Xiao Zirong heard this, he was not in a hurry. After the next year, he can prepare other things now, such as the glass that is very much needed for the synthesis of chemical reagents.

Xiao Zirong laughed when he decided to make glass, feeling that this thing is probably one of the necessary crafts for time travelers.

Glass is called colored glaze in these years. There have been many colored glaze products, and it is one of the seven treasures of Buddhism. However, the colored glaze production process in Qi State is not very good, because there is no suitable raw material, and there is no special one for the time being. suitable substitute.

In fact, ordinary sand can also be used to make glass, but the biggest problem is that there are many impurities and it is not transparent enough.

And what he needs is glass with high transparency, so that it is more convenient to observe the situation after the mixing of those chemical reagents, and if the scale is marked on it, it should be more intuitive to understand the ratio of addition.

The raw material used by Xiao Zirong is silica sand, which is usually produced next to the crystal, and the location of Xiao Zirong is good because it is not far from Qushan County, which is rich in crystal.

Of course, the name Qushan County is very unfamiliar. This place is actually Donghai County in later generations. At that time, it had the reputation of the crystal capital of the world.

What Xiao Zirong wanted was not the crystal, but the silica sand produced next to the crystal.

After the silica sand is ground, calcium carbonate is added according to a certain ratio, that is, shell powder, and lead ore and roasted seaweed are calcined to form glass, and the glass produced has few impurities, and there is almost no need for the next step of impurities remove.

The production of glass is not difficult, except for the use of a lot of artificial heating, everything else is fairly simple, but how to make the glass into the desired shape after making the glass is not easy.

This involves glass blowing, but pure labor is easy to find. For example, this kind of glass blowing requires certain skills. It requires two people, one blowing and the other doing the shaping.

Nowadays, both blowing and shaping require experience. At first, Xiao Zirong thought that he only needed to give the blueprint to the Ministry of Industry. Flat glass in the shape of a flask.

Xiao Zirong couldn't believe it holding the flask-shaped plate glass, he looked up at Zhai Xi and asked, "How did you make it look like this?"

Zhai Xi was a little dazed: "Isn't that what you drew?"

Xiao Zirong: ...

All right, this is his fault, he should draw a three-dimensional image for Zhai Xi, but after he drew a three-dimensional image, he found that no one could understand his drawing at all.

In other words, no one can understand what perspective is, so they can't see what's going on with this bottle at all.

Xiao Zirong rolled up his sleeves: I will do it myself!

Of course, even if he came by himself, he didn't really blow the glass bottles, but the one who did the shaping.

On the first day, he looked at the potted glass bottle with an uneven bottom in his hand and fell into deep thought.

The next day, the bottom was finally flat, but the entire flask was in a distorted state, and the walls were still not smooth.

On the third day, the bottle wall became smooth, but the whole bottle was in a crooked state.

Xiao Zirong looked at the finished product and thought about whether to use it or not.

In the end, Zhai Ling couldn't stand it anymore. He took the tool from him and made one. Although it wasn't perfect, it was definitely better than his.

Xiao Zirong let go and left very calmly, and began to ask people to make glass windows for him.

Wouldn't it be too wasteful not to make glass windows after all the glass is made.

So Xiao Xuexing watched Xiao Zirong bring a group of people to the city lord's mansion to tear down the windows, and couldn't help being a little surprised: "Who made you angry?"

Xiao Zirong:? ? ?

He turned to look at Xiao Xuexing: "How did you think of it?"

Xiao Xuexing put down the book in his hand and asked: "It's not that someone made you angry, why are you demolishing the house?"

Xiao Zirong glanced at the book he put down: "Sixth Grade Mathematics Volume II"

He couldn't help but twitch the corner of his mouth, brother, don't you think this book doesn't match your peerless appearance and elegant temperament?

However, I have to say that Xiao Xuexing's progress is quite fast. Two days ago, he was still studying elementary school Chinese. In these two days, if he switched to mathematics, he has already seen the sixth grade.

While thinking about these things in a nonchalant manner, he said, "I didn't demolish the house, I just wanted to change the window."

Xiao Xuexing nodded and said: "Although shells are novel, it's better to replace them with silk yarn."

But...it doesn't have to be that extravagant.

Although the process required for glass is relatively complicated, the cost is actually not too high, at least much lower than that of spun yarn, and it is going to be winter, using spun yarn means that the heat in the room is easily lost. If it is covered with other Things will block the light again.

Xiao Zirong waved his hand and said, "We don't need that, let's use Liuli."

Xiao Xuexing paused for a moment, suddenly feeling that his younger brother seemed to be more generous than him.

It's just that when all the glass was delivered and started to be installed, Xiao Xuexing looked at the bright light in the room and felt that it was okay to be a little expensive, at least the effect looked really good.

Now that the glass windows were all there, Xiao Zirong simply decided to get out the mirror. Anyway, they can get out together, and maybe they can be sold for money.

Now that Taoyuan City has appeared in front of the public, it needs a pillar industry. Even if there is salt, it is not safe. Once the method of making salt is spread, with such a long coastline in Qi, Taoyuan City can be used in other places.

So something else is needed, and a bunch of derivatives of glass would be nice.

It's just that mercury is needed to make a mirror from glass, and mercury is not difficult to get. You can get mercury by directly heating cinnabar.

After getting out the mercury, Xiao Zirong realized belatedly: The mercury is all out, is the thermometer still far away?
