Hand over the jade seal first [Infrastructure]

Xiao Zirong explained: "Look, some doctors usually burn a knife with a fire and spray a sip of wine when they clean up a sore. The wine is to inhibit the wound from festering."

Xiao Xuexing frowned: "It's not right for you to say that, there is a lot of wine in the army, and the military doctors have used it, but..."

Xiao Zirong shook his head and said: "That's because the quality of the wine is not good enough, or there are too many impurities in it, and those impurities can easily cause wound ulceration. The wine I just gave you is relatively low in purity. I made a wine with a higher purity, but this wine is undrinkable, and you will be poisoned if you take a sip, but it is the best thing to use for debridement.”

Xiao Xuexing asked: "Are you sure?"

Xiao Zirong thought for a while and said, "If you don't believe me, let's try it."

How else to try?Of course, there is a wave of animal experiments.

But they didn't have mice here, so they couldn't use them for experiments. In the end, they had to find two chickens, all of them had a non-fatal wound, and then cleaned one with alcohol, and left the other alone. The cloudy wine was washed, and the same medicine was used.

In addition, it is also disinfected with turbid wine and alcohol every day.

After today, the wounds of the two chickens appeared different. Although there was no ulcer on one body, it was still slightly red and swollen.

Xiao Xuexing is very familiar with this kind of situation. At this time, the competition is luck and personal physique. If luck and physique are good, you can survive it. If you are not good enough, you may not be able to survive.

The wound on the other chicken had almost healed by this time.

Such an obvious contrast is enough to explain the situation.

After seeing it, Xiao Xuexing said with emotion: "It's a pity."

Xiao Zirong turned to look at him: "Huh?"

Xiao Xuexing said: "This thing... I'm afraid not many people can use it."

"Ah?" Xiao Zirong was at a loss for a moment: "What do you mean?"

Xiao Xuexing looked at him and said carefully: "It means that there is not so much food to supply these."

Although nobles drink like running water, it is still different from alcohol. Xiao Zirong also said before that alcohol needs a lot of alcohol.

Grain winemaking has always been restrained, otherwise, if a large amount of grain is used to make wine to supply nobles, the result may be that many people will starve to death.

After hearing this, Xiao Zirong suddenly realized that this is indeed a problem. When the productivity cannot be reached, even if it is made, it cannot be promoted on a large scale.

Especially alcohol is really expensive to use.

You must know that even if the science and technology of the later generations are so advanced, it will take 70 to [-] years to get rid of poverty. In the current state of Qi... where can there be so much food to do this?

Xiao Zirong asked with some hesitation: "Then... the previous Quyuanli and waterwheels are useless? Could it be that the grain production can not be increased?"

Xiao Xuexing said: "It is useful, but no one can say how much it can be increased. Even if it can be increased, His Majesty will not agree."

Xiao Zirong thought about Xiao Xuan's character, but it's not surprising

He thought carefully for a long time and finally said: "Actually, fruit wine...is not bad."

Xiao Xuexing was a little surprised and asked, "Fruit wine? What kind of fruit wine?"

Xiao Zirong said: "It is the fermentation of fruit to make wine, and alcohol will be produced in it, but it is only a small amount, but it is also a purpose."

Ordinary people will starve to death without food, but if there is no fruit, it may just be nutritional imbalance.

Xiao Xuexing suddenly asked: "Wine?"

Xiao Zirong nodded but quickly said: "I don't need that thing."

Grapes are a very luxurious thing for the current state of Qi. Although grapes were brought back to the Central Plains by Zhang Qian during the Western Han Dynasty, the places suitable for grape growth are almost all in the hands of the Northern Wei Dynasty. In the south...at least there are no suitable varieties for now.

So wine is very expensive in Qi country, most people can't afford it, Xiao Zirong never even saw Xiao Xuexing drink it.

Of course, it may also be that Xiao Xuexing simply doesn't like it.

Xiao Xuexing nodded and didn't speak, Xiao Zirong simply said: "Hey, anyway, I said that you haven't seen it, so why don't I get some for you, well, peaches just came down early, how about peach wine?"

Originally, Xiao Zirong didn't like wine very much, but fruit wine is no different from drinks to him. It tastes fragrant and sweet. It wasn't obvious if I didn't say it before, but now I'm a little greedy.

Xiao Zirong did what he said, and Xiao Xuexing saw that his enthusiasm was not so much for alcohol, but because he was greedy, so he just let him do it.

Xiao Zirong asked someone to get a batch of peaches and wine with a relatively low alcohol content. Although he said before that fruits can ferment on their own to produce alcohol, what he is going to make now is fruit wine, and of course he needs to add ingredients for it to taste better.

But after getting the alcohol, he discovered one thing - peach wine needs sugar to taste, but most of the sugar now is caramel, brown sugar... that is, there is stone honey shipped from far away Persia, But the problem is that there is no rock sugar.

Of course, this difficulty is difficult for a foodie.

Isn't rock sugar the result of crystallization of white sugar?

He turned around and asked Xiao Xuexing to send someone to get some stone honey, and then got some yellow muddy water to decolorize and purify the stone honey. After getting the white sugar, he poured the white sugar into the water to melt it.

After the white sugar is completely melted, pour oil into the pot and put the sugar water in to boil. After a while, add the saturated alum solution at room temperature.

Finally, pour the sugar water into the container. During the crystallization process, it is afraid of the cold but not the heat. The greater the vaporization of the crystallization water, the higher the crystallization rate.

However, Xiao Zirong is not very sure about the temperature. It will take at least seven days for the crystallization. No matter how much Xiao Zirong craves peach wine, he can only wait.

After seven days, the rock candy was made. Seeing the crystallized rock sugar, Xiao Zirong was very happy. He asked someone to wash the peaches and dry the skin with a clean cloth before cutting them into small pieces. A piece of land was put into a glass container, and then wine and rock sugar were put in, sealed and placed directly into the ice cellar.

It takes at least a month for the reaction from peaches to peach wine, and it is impossible for Xiao Zirong to spend this month waiting for it, so he has to continue to make aniline out after the tossing is over.

Ethyl acetate has been produced, and the rest is coal tar refined from coal.

This thing sounds inconspicuous, and coal has been used as early as the Western Han Dynasty, but the problem is... Taoyuan City has never existed!

Taoyuan City uses only wood and charcoal. Because coal is inconvenient to transport, Xiao Zirong is not in a hurry. He also thought about getting some coal in sooner or later. Among other things, the flames produced by coal burning The temperature can be higher.

As a result, I didn't expect to use it so soon, and there are not many that can be used now, because sulfonamide is not produced in large quantities, so Xiao Zirong directly asked Xiao Xuexing to get some coal tar over.

Yes, what he wants is actually not coal, but coal tar after burning coal.

In fact, coal resources are also relatively scarce in Qi State. For the same reason, the existing coal mines are also found in the Northern Wei Dynasty.

Of course, there must be coal in the country of Qi, but the problem is that it may not be easy to mine. Some of the coal mines in the north are even open-pit, so you can just mine them directly.

In the current state, it is almost impossible to find it.

Xiao Zirong kept this matter in his heart, and planned to talk about it after Xiao Xuexing's medicine was made.

After getting the coal tar, wash it with hydrochloric acid, and then add the previously prepared ethyl acetate to get aniline directly.

After the aniline was made, Xiao Xuexing turned around and ticked the record sheet. The final step of synthesis of sulfonamide requires five materials. Now Xiao Zirong has obtained chlorosulfonic acid, ammonia water and aniline, and the remaining two are Sodium bicarbonate and acetic anhydride.

There are not many things needed for sodium bicarbonate, just two things, one of which is carbonated water and the other is sodium hydroxide.

Among them, sodium hydroxide is easier, and sodium hydroxide can be obtained by directly electrolyzing brine.

The carbonated water is stuck on the carbonic acid.

When Xiao Zirong was alive, well, even before he came here, he also made carbonated drinks at home.

But at that time, sodium bicarbonate was used, which cannot be used as a reference at all.

But it's not impossible to do it, Xiao Zirong just poked around in the vast sea of ​​books for a long time and finally found that...he had to lead people to do manual work.

Just when he was about to take people to do manual work, Xiao Ji suddenly came to him.

Xiao Zirong looked at his embarrassed face and asked curiously: "What's wrong?"

Xiao Ji looked left and right, Xiao Zirong's heart skipped a beat, thinking that something important had happened, he waved his hand to make everyone retreat before asking in a low voice: "What's going on?"

Xiao Ji leaned in front of him and said cautiously: "Well... If you make a request to the Prince Regent, he will usually agree, right?"

Xiao Zirong's heart suddenly sank, it must not be a small matter related to Xiao Xuexing, and he still needs to make a request.

Although Xiao Xuexing did agree to all his requests, but after thinking about it, he still said: "It depends. If it's something particularly outrageous, I don't dare to say it. I'm afraid he will beat me up if I say it."

Xiao Ji's eyes widened: "How could he beat you?"

Anyone with eyes can tell how much Xiao Xuexing pampers Xiao Zirong, Xiao Zirong has done nothing that would have caused Xiao Xuexing to explode on others.

Xiao Zirong looked at him with a face full of words: "It's true, but he saved me face, so don't tell others."

Although Xiao Xuexing only beat him once, and later apologized to him and admitted that he was too impulsive, but... that was beaten, he didn't lie and there was nothing wrong with him!

Xiao Ji nodded and said: "But don't be nervous, it's not a big deal, just...can you ask him to show my father the moon lamp again?"

Xiao Zirong:? ? ? ? ?
