Hand over the jade seal first [Infrastructure]

In the past two days, in order to produce chlorosulfonic acid, Xiao Zirong almost threw scheelite into the back of his mind.

However, his lack of attention does not mean that his subordinates can be lazy, so everyone is still working hard to extract scheelite.

The matter of extracting scheelite does not require Xiao Zirong to do it himself. In fact, he has taught many methods and steps of making materials to his subordinates, and there is no need for him to watch in person.

It’s just that the matter of making sulfonamide is extremely important to him, and he can’t sit still if he is asked to wait for the news at home. Why not go to the preparation room and follow along, and have someone record all the steps by the way, and there are some things that you may not have noticed The wrong methods are also recorded, so be vigilant not to repeat them in the future.

Xiao Zirong was a little surprised when the news of scheelite was extracted, but it was good news after all.

Now that the scheelite has been extracted, the filament has been settled, and the electric light seems to be on the agenda.

It just so happened that Xiao Zirong wanted to change his mind recently. He used to deal with sulfuric acid and hydrochloric acid every day for a piece of chlorosulfonic acid, and there was very dangerous hydrogen chloride gas in between.

When I was in the preparation room, it was because I was wearing a gas mask, otherwise the people below would definitely see Xiao Zirong’s nervous expression all the time—hydrochloric acid, sulfuric acid, and chlorosulfonic acid are all dangerous substances, and if you are not careful, you will be killed. accident.

The upside, though, is that their explosives can also be upgraded.

For this reason, Xiao Zirong asked Xiao Xuexing specifically: "Brother, will you start a war with the Northern Wei Dynasty soon?"

Xiao Xuexing thought he was worried and said, "The Northern Wei Dynasty will be powerless to attack within five years, so don't worry."

Xiao Zirong waved his hands and said: "I'm not worried about them, I just thought of a way to make the gunpowder bamboo tube more powerful and more stable, but I don't have time to do it now, if I don't want to shoot, I will put it back first, I'll toss it after I make the medicine."

Xiao Xuexing: ...

Well, it seems that the Northern Wei Dynasty is the one to worry about.

Xiao Xuexing touched Xiao Zirong's dark eyes with some distress and said, "Didn't you say it before, don't be so anxious, you have to take care of yourself first."

Xiao Zirong smiled and said: "Do you think I am alive and kicking now? And brother, don't be pressured. Once this medicine is made, many people will benefit from it. Think about it, many soldiers injured on the battlefield will be saved. Not only them, but also other injured people, this is a great merit!"

Xiao Xuexing couldn't help laughing, but he knew very well in his heart that if it wasn't for him, Xiao Zirong might not have done that kind of sulfonamide.

After all, in Taoyuan City before, Xiao Zirong's subordinates were not without injuries, even Xiao Zirong himself was injured, and he didn't even think about doing this at that time.

Don't say that he only brought help to Xiao Zirong when he came. This time, the people under him in the pharmaceutical industry were only responsible for searching for various materials. Without him, Xiao Zirong might spend some time searching for this thing. In terms of materials, but definitely not impossible.

Seeing that he didn't speak, Xiao Zirong said simply: "Okay, I'll give them a holiday, and I won't bother them these two days. Well, I'll do something else for fun."

Xiao Xuexing looked up at him, Xiao Zirong immediately said obediently without waiting for him to speak: "Be sure to come back on time for dinner and sleep well."

Xiao Xuexing paused, looked at Xiao Zirong and asked tentatively, "Run'er, do you think brother is annoying?"

Xiao Zirong looked at him inexplicably: "Ah? Why?"

Xiao Xuexing pretended not to care and said: "I heard from many colleagues that when the children grow up, they don't like them to take too much care."

This is true. Many ministers have spent a lot of energy in order to discipline their children.

These days, the sons of aristocratic families are not all dudes, or the probability of being born as dudes is very low. Those kind of dudes are basically the ones with no hope of inheriting the family business, and the family is not particularly short of money.

The real heirs need to be taught well, otherwise, if they grow crooked, they will directly implicate the family to destruction, and then they will have no face to face their ancestors even under the nine springs.

After hearing this, Xiao Zirong understood a little bit, leaned over and took Xiao Xuexing's hand and said, "It's okay, I like my brother to take care of me."

Xiao Xuexing turned to look at him in surprise: "Really?"

Xiao Zirong nodded earnestly and said: "Those children are living in the blessings and don't know the blessings, I am not like them."

He is not a child, so he knows the seriousness, not to mention that he has been a lonely ghost for a long time, and he has not integrated into this world for a long time at the beginning.

Even when he established Taoyuan City in the beginning, in addition to his responsibility to the little ladies, it was more of a game mentality.

He has no ties in this world, so he feels that he can do whatever he wants and do whatever he wants.

Now with Xiao Xuexing, he has some connection with this world, allowing him to truly integrate into it.

And those who have never lost will not know how precious this bond of concern is, so even if Xiao Xuexing is in charge of him, he will not say anything.

What's more, Xiao Xuexing is very measured, even if he cares about him, that is, he should be more strict in terms of basic necessities of life, food, housing and transportation, and let him do everything else, unless Xiao Zirong suffered a loss or was about to suffer a loss, he would call people over, but not Unreasonable reprimand, but breaking apart and crushing to make sense.

The only time Xiao Xuexing was furious was when he slapped him twice because he ran into the rain, but those two slaps didn't use much force, and he didn't even need to use medicine. Obviously Xiao Xuexing was holding back his strength at that time.

Xiao Xuexing thought about it, and felt that Xiao Zirong was more and more sensible, so he rubbed his head and said, "Go."

Xiao Zirong hugged her head and complained, "Don't rub it, don't rub it anymore, if you rub it again, you will have to comb your hair again."

His hair is already very long now, and it's annoying to comb it every time, even if he doesn't have to do it himself.

Xiao Xuexing watched Xiao Zirong run away with his head covered, and couldn't help but pursed his lips and smiled.

Xiao Zirong ran to the Ministry of Industry in a good mood, and Zhai Xi, who was dealing with matters in the Ministry of Industry, was startled when he saw him: "City Lord?"

Didn't you say you won't be here today?She has given the preparation room a vacation.

Xiao Zirong said directly: "I heard that the scheelite has been extracted, so I'll come over and have a look."

Is scheelite still far behind when there are electric lights?When Xiao Zirong thought of being able to replace all the lights in the house with electric lights, he couldn't help being very excited, how could he still sit still?

Only then did Zhai Xi heave a sigh of relief, and quickly called Zhai Ling over, because her younger sister was watching over this aspect.

This matter is also important and not so important. Other experts in the Ministry of Industry were transferred to develop sulfonamide, so Zhai Xi simply asked his sister to keep an eye on scheelite. After all, if this thing can be made, it will be a success.

As for the production process of sulfonamide, anyway, she can still teach Zhai Xi after Zhai Ling signs a non-disclosure agreement.

As soon as Zhai Ling heard her sister calling her, she knew what it was for, and directly brought the finished scheelite over.

This is the first time for Xiao Zirong to see the extracted scheelite raw material, which is a kind of silvery white crystal, which looks strange and beautiful.

After a glance, he gave Zhai Xi the request to make filament and asked, "Can it be done?"

Zhai Xi immediately felt relieved when he saw it: "No problem."

Isn't it just doing handwork?As long as she doesn't go to the preparation room for chemical reactions, she's fine.

It's not because of the chemical reaction, it's mainly because...it's too complicated, and many times she can't figure out how those things turned out like that, even if the city lord told her the principle of the whole process, she often seemed to be confused. understand non.

Although the city lord comforted her and said that she would explain this in detail in the future, she was under a lot of pressure, fearing that someone else was smarter than her and knew more than her, thus replacing her.

If it is about mechanism skills, then she dares to say that even the officials of the court are not as good as her.

But when it comes to chemical reactions...Zhai Xi is also a novice.

It is also because of this that Zhai Xi attaches great importance to the things Xiao Zirong ordered. It was almost not long after Xiao Zirong made the request, and Zhai Xi asked someone to produce what he wanted. Four days.

In the process of making the filament, the glass shell of the light bulb is naturally done. This thing is not a problem for those veterans who are already familiar with it.

At the same time, Xiao Zirong also had someone make the tail of the lamp, which is not a particularly complicated thing, at least it is much simpler than preparing chlorosulfonic acid.

During this process, Xiao Zirong was equivalent to a vacation, but he was not idle, and began to have people pull the wires to the city lord's mansion.

It was also thanks to him that he had thought about this a long time ago, so he prepared a lot of copper wires at the beginning. As for the electricity... just supplying a city lord's mansion is no problem, if there is more, he can only get another generator.

He has temporarily shelved things like electrifying the entire Taoyuan City, and it will definitely be realized, but the problem is too complicated, so we have to wait until he gets sulfa out.

The biggest problem with wires being brought into the city lord's mansion is how to make it beautiful and safe.

Xiao Zirong didn't really want to get in the air at first, but it's okay to put the wires in the air now, but the problem is that there will be more wires in the future, and all kinds of cables in the sky are really unsightly.

However, if we go underground, the current technical level cannot reach it. Nowadays, the lifespan of these wires is not high, and they have to be replaced every now and then. If they are buried underground, it will be too troublesome to dig them out every two or three months.

In the end, Xiao Zirong simply made a cable channel, a narrow strip, with a cover on it, and the cables go through it, and the cover needs to be lifted up if maintenance is needed, and the channel is hollowed out, in order to prevent Rain and water.

After all the cables were done and the only thing left was to connect the generator and the light bulb, Xiao Zirong discovered a very important thing - he couldn't make the inert gas inside the light bulb.
