Hand over the jade seal first [Infrastructure]

Because only the electric blower in the preparation room can use electricity, even a temporary power outage did not cause much impact. On the contrary, everyone at the scene was very calm. After finding that the blower stopped running, manpower was directly used to continue.

At this time, Xiao Zirong's feet were almost healed, and he rushed to the location of the generator immediately after hearing the news.

When they passed by, Zhai Xi was leading people to overhaul the generator.

After seeing Xiao Zirong, Zhai Xi said guiltily, "City Master, I didn't pay attention and didn't protect the generator properly."

The water wheel of the generator brought a fish, but the fish struggled and went to the generator and hit the generator with a strong magnet, causing it to stop running.

Xiao Zirong waved his hands after knowing it and said, "It has nothing to do with you, I forgot to make a shell for this thing."

If he doesn't say it, others probably won't dare to say that he is not perfect.

Xiao Zirong deeply felt that this was not good. What he wanted was a helper who could help, not a bunch of tool people. These people should have their own thinking and tell him when they find something wrong.

Although Xiao Zirong has a huge library as a foundation, this library also requires him to search and read what he wants to know in order to get the answer.

In other words, if he didn't think of that point himself, then the relevant books would be as if they didn't exist.

Xiao Zirong is also a mortal body. He can make a lot of things because these are the most basic things in later generations. Even if he has never seen them, he has learned them in textbooks. When you are bored in the library, you just read books, abruptly making your knowledge reserve bigger.

But this does not mean that he is omnipotent, he must also have unexpected times, and at this time, others need to remind him.

Xiao Zirong rubbed his temples with some headaches. This habit needs to be cultivated a little bit, because these people under him were ordinary people and even ordinary people who had suffered many disasters. Afterwards, Rong naturally believed in him, obeyed him and never said anything, and worshiped him.

In this situation, they didn't even think about reminding Xiao Zirong of what was wrong, or even thinking about refuting each other.

In fact, Xiao Zirong has long been aware of this situation, but he has subconsciously ignored it before, or to him, compared to things related to people, especially the way of controlling people, he is really not good at it. These.

Since Xiao Zirong had the intention, he directly asked Zhai Xi: "How do you think to prevent this kind of thing from happening in the future?"

On weekdays, Xiao Zirong would ask them this way when teaching them, and Zhai Xi was also very used to this kind of question. After thinking for a while, he said, "It's better to put a shell on the outside, but the shell needs to have sufficient ventilation and heat dissipation."

The magnetic field power generation itself does not generate much heat, but the brushes still have heat dissipation requirements to maintain the stability of the generator.

Xiao Zirong nodded and said, "Then let someone design one."

Zhai Xi immediately said: "City Master, let me do this in person."

Xiao Zirong shook his head: "I have other things for you to do."

Zhai Xi asked curiously, "What does the city want me to do?"

These days they are busy making sulfuric acid every day and trying to extract scheelite. Before the scheelite is extracted, Xiao Zirong said that they will not send them new tasks.

Xiao Zirong said: "Make batteries!"

Zhai Xi suddenly looked confused: What is a battery?

This power outage reminded Xiao Zirong that such incidents might not be rare in the future. Even if there were no accidents, the generator or circuit would need to be overhauled once or twice a year, especially in winter.

Xiao Zirong vaguely remembered that even in the south in winter, the power lines were easy to freeze, so they had to send people to remove the ice every year. Now there are not many places where they use electricity, so there is no such trouble for the time being, but they still have to plan ahead.

The existence of the battery is to be prepared. If there is a planned power outage, the preparation room can be shut down in advance. But if there is a sudden power outage, the battery will be needed to maintain the operation of the equipment until the generator is repaired.

In fact, the production of batteries is not difficult. Xiao Zirong directly asked someone to dig a basement under the preparation room, and then asked someone to build two huge pools inside. Of course, the pools are not filled with water, but sulfuric acid. .

Put lead plates in the sulfuric acid, and after the two pools are connected, the entire basement is a huge storage battery.

It happens to be able to store excess electric energy in the battery. In order not to produce too much electric energy, Xiao Zirong had someone control the speed of the waterwheel. After all, the faster the waterwheel turns, the more electric energy it will generate. Of course, for The stability of power output also has an impact.

Now that there is a battery, just connect a part of it and store it in the battery.

Because the generator is relatively primitive, Xiao Zirong asked someone to overhaul it once a month. The parts and components were prepared in advance, and if they were found to be excessively worn, they should be replaced quickly.

This is just enough for the battery to keep the blower running.

But the only disadvantage is probably that the sulfuric acid that was obtained before is basically used for battery production.

But it doesn't matter, there is no rush anyway, the extraction of scheelite is secondary, and his focus is always on pharmaceuticals.

After getting electricity, Xiao Zirong started to prepare sodium hydroxide, which is not difficult, just electrolyze salt water.

Then there is the production of hydrochloric acid, but the production of hydrochloric acid requires a set of special equipment, the most important of which is probably the dripper.

The shape of the dripper is very strange. It is in the shape of a pot as a whole, except that there are spouts with large openings on both sides. There is a glass tube in the middle of the pot to collect the dripping water droplets. On the top of the pot is a Funnel, specially used for dripping water.

Sulfuric acid and salt will form hydrogen chloride gas after heating. The hydrogen chloride gas is introduced into the dripper through a glass conduit, and then absorbed by the water droplets dripping from the dripper to become hydrochloric acid.

This process sounds quite simple, even if it is the production of glassware, Xiao Zirong doesn't need to watch it personally, he just needs to hand over the drawings to the subordinates.

However, for a hydrochloric acid, Xiao Zirong spent two days in a daze. If Xiao Xuexing hadn't personally caught him back to eat and sleep, he might wish he could live in the preparation room.

Xiao Zirong didn't understand, why could she always make mistakes with such clear steps?

Among them, the problem that has troubled them the longest is the sealing problem. If hydrogen chloride gas is to be smoothly introduced into the dripper, it must have sufficient sealing.

At that time, Xiao Zirong had already used the best sealing material, even gum, but the air still leaked.

This led him to directly use liquefied glass as glue, directly stick the glass tube to the heated glass vessel, and then connect the dripper, thus avoiding air leakage and successfully collecting hydrochloric acid.

Now that the hydrochloric acid has been produced, Xiao Zirong is ready to go all out and directly produce chlorosulfonic acid, one of the most important materials of sulfonamide.

As long as the sulfur is heated to a certain extent, it will become a liquid state, and then continue to heat to obtain a gaseous state. The gaseous sulfur is exported through a catheter, condensed with water in the middle, and added to hydrochloric acid for an internal reaction to obtain chlorosulfonic acid.

After the chlorosulfonic acid was finally prepared, Xiao Zirong glanced at his material list. In addition to chlorosulfonic acid, there were still aniline, sodium bicarbonate, and acetic anhydride in the final materials.

Compared with these things, except for aniline, chlorosulfonic acid is probably the best, but a single chlorosulfonic acid made him toss for several days.

If you don't go back and take a good rest, you probably won't be able to proceed to the next step.

After finishing the chlorosulfonic acid, Xiao Zirong said very tiredly: "Okay, everyone will have two days off these two days, and the rest will be discussed after the holiday."

After he finished speaking, the whole preparation room cheered suppressedly.

Xiao Zirong was tired these two days, and they were even more tired than Xiao Zirong. The difference was that Xiao Zirong was tired from his brain, and he had to constantly search and think about various reaction equations to find the most suitable and simplest method.

After Xiao Zirong came out of the preparation room, he took off his protective clothing and saw Xiao Xuexing standing aside and looking at him with a cold expression.

He paused and looked outside with a guilty conscience—well, it was already the beginning of moonlight.

Yesterday he also promised Xiao Xuexing that he would go back to eat early today, but because the preparation step had reached the most critical step, Xiao Zirong was reluctant to let go of what he was doing, and it dragged on until now.

Xiao Zirong rubbed against Xiao Xuexing's side with a guilty conscience, Xiao Xuexing took a look at him and turned around without saying a word, there were too many people here, Xiao Zirong was also a vassal king and the lord of a city, in terms of status, he was on an equal footing with him, he It's not good to train him in front of so many people.

It's fine if it's a child, but Xiao Zirong has grown up.

After getting into the car, Xiao Xuexing sat down and asked without waiting for Xiao Zirong to speak: "How did you promise me yesterday?"

Xiao Zirong almost didn't kneel down to him: "I know I was wrong, I was too involved and didn't pay attention to the time, and they didn't dare to disturb me."

He was worried that Xiao Xuexing would vent his anger on others, so he took them out first. Anyway, even if Xiao Xuexing was angry, he would not hurt him, but if Xiao Xuexing felt that the people around him had not fulfilled their responsibilities, then it would not be a matter of punishment, and there might even be someone He lost his life for this.

After all, many of the manual work in the preparation room was done by slaves. For officials, Xiao Xuexing would still allow a bit of leeway, but if the slave made a mistake, he would definitely not let it go easily.

Xiao Xuexing knew Xiao Zirong's careful thoughts as soon as he heard it, but he didn't intend to hold those people accountable.

Again, those people are all under Xiao Zirong's subordinates. If something serious happens to Xiao Zirong, such as what happened that night, it's fine for him to be ruthless. If it's not a big deal, he shouldn't interfere too much. .

Thinking of this, Xiao Xuexing felt a little irritable for no reason. He has always been restrained, and he can bear other things, but it happened to Xiao Zirong. He hoped that the other party could protect him and treat him well. If the other party couldn't do it, he didn't mind taking care of it.

But reason tells him that he can't do it for him.

Because he was trying to restrain himself from reaching out too much, Xiao Xuexing's expression was not very good-looking, he just nodded calmly and said: "Remember next time."

However, Xiao Zirong mistakenly thought that he was still angry, and cautiously approached Xiao Xuexing to be good-looking and said: "It's my brother's birthday in a few days, I want to spare a day to spend my birthday with my brother."

After hearing this, most of the irritability in Xiao Xuexing's heart went away, and he glanced at Xiao Zirong and said, "You don't have to be so serious, just let me worry less."

Xiao Zirong had a cute face: "Yeah, I see, brother, I will take you to have fun on your birthday."

Only then did Xiao Xuexing have a faint smile on his face, but it was only for a moment, and he said with a straight face: "Look at your performance, if you don't eat and sleep well, don't even think about leaving the door."

After saying these words, Xiao Xuexing didn't know why his heart fluttered for a moment, but he quickly put this matter behind him and didn't dare to think about it any more.

Only then did Xiao Zirong heave a sigh of relief, but at the same time he was a little worried. He thought about what gift to give Xiao Xuexing for a long time, but no matter what gift he felt, something was missing.

Precious ones, Xiao Xuexing is richer than him, novel ones... He couldn't think of anything suitable for him for a while, and he felt that choosing a birthday gift for the emperor would not give him such a headache.

When Xiao Zirong was struggling, good news came from the preparation room: the extraction of scheelite was successful.
