Hand over the jade seal first [Infrastructure]

Xiao Zirong really wanted to know what happened to make Xiao Xuan give him the aphrodisiac.

But it was useless to ask the people below about this kind of thing, so he had to leave the medicine and said: "I will keep the medicine, you go back first."

The little eunuch didn't say much. Originally, he came here simply to give a bowl of medicine, and more to give Xiao Zirong's prescription.

After the little eunuch left, Xiao Zirong turned to look at Xiao Xuexing with a shocked expression: "Did your Majesty misunderstand something?"

Xiao Xuexing lowered his eyes and said: "Probably because you mistook the palace lady for a female ghost last time, which made him misunderstand."

Well, he ran to tell Xiao Xuan that Xiao Zirong was not good at such things, so let's not talk about it.

It felt like if he really said it, his younger brother might have to fight him hard on the spot.

Xiao Xuexing was not afraid of Xiao Zirong's attack, but he was afraid that he would accidentally hurt him.

However, in fact, he didn't lie before, he and Xiao Zirong also slept together for a while, it can't be said that Xiao Zirong has no function in this aspect, but he is not so passionate.

Thinking about Xiao Zirong's age, when he was just young, but he never soiled the bed, it's very wrong.

Xiao Xuexing also came from this age, and he was never like this when he was burdened with blood and hatred. Sometimes the impulse of the body is not easy to suppress, and he can ignore it on weekdays, but it is easy to release it when he is asleep.

Thinking of this, Xiao Xuexing was also a little worried, so he walked over and took a look at the prescription and said: "This prescription is relatively mild, and it can strengthen your body if you drink it for nothing. One bowl a day is nothing."

Xiao Zirong looked up at him suspiciously and said, "Do you know something?"

It's a three-point drug, so how can it be nothing?

Xiao Xuexing often needs to drink medicine, so he should be very familiar with it, so even if Xiao Zirong got caught in the rain, he just had someone pour Xiao Zirong a bowl of ginger soup that didn't taste very good, and didn't let him drink it. medicine.

Xiao Xuexing's expression was as usual: "You know what? This is not a top-secret matter. Your Majesty just cares about your body. You have lived among the people since you were a child, and then you ran to this barren mountain. It was time for you to grow your body. You lacked food and clothing. It must still have an impact, it’s not too late to make up for it, and if you delay it, I’m afraid you’ll regret it later.”

Xiao Zirong muttered, "I think it's pretty good."

Xiao Xuexing patted his head and said coldly: "Who wants to grow taller every day?"

Xiao Zirong: ...

Well, now in the whole family, he is the shortest, and Xiao Xuan is taller than him even if he has a disabled leg. Gan!

Xiao Zirong angrily took the bowl of medicine and drank it down.

I don't know if Xiao Xuan specifically reminded him that the taste of this bowl of medicine is not so hard to describe, maybe he also put licorice or something to make the taste better.

But the taste of licorice is hard to describe for Xiao Zirong.

After Xiao Zirong finished drinking, he got up and said: "Okay, I'm going to get busy, you can play at home obediently, and take a good look at the house."

As he spoke, he stretched out his paw to Xiao Xuexing's head and touched it very boldly, but he only touched it lightly, and then ran away like a rabbit.

Xiao Xuexing stood on the spot and looked at his fleeing figure and said calmly: "Are you planning to come back?"

He didn't want to chase, but if he really wanted to, he would never be able to escape at Xiao Zirong's speed.

And Xiao Zirong waved his hand very coolly after hearing his words, quite a feeling of letting go of the aftermath after being happy.

But Xiao Zirong wasn't making excuses, he was really busy.

After Xiao Xuexing's birthday passed, his focus returned to the pharmaceutical side again. It happened that everyone had almost finished their holidays, and everyone was full of energy, suitable for squeezing... No, no, it is suitable for continuing research.

Before Xiao Zirong came, he had people prepare wine and vinegar, and of course sulfuric acid was also essential.

What he is going to produce today is ethyl acetate, which is needed for the aniline that is necessary for sulfa.

Ethyl acetate is the simplest method of direct esterification. Because it is the first time to make it, Xiao Zirong decided to let others do it, and decided to do it himself.

After all, it was something new. He stood aside and commanded, saying that the opponent's one step is not as fast as his own.

Ethyl acetate itself uses acetic acid and ethanol as raw materials, but when Xiao Zirong passed by, he saw the jar of turbid wine and remembered that there is no high-purity ethanol these days.

What else is there to say, just distill it directly.

Fortunately, there are still kettles these days, so Xiao Zirong doesn't need to make any more effort to make distillation vessels by himself. Instead, he will have people separate part of the wine during the distillation process and put them into small wine jars. Seal it up and prepare to bring it back for the emperor and his son and Xiao Xuexing to taste.

As for the by-products produced during the production process, Xiao Zirong said that he is used to it, and this kind of thing is normal.

Xiao Zirong was not ready to start making ethyl acetate until he distilled to the final alcohol with a high purity.

The direct esterification method is to use vinegar and alcohol as raw materials, and then use sulfuric acid as a catalyst for direct esterification, but at this time, ethyl acetate is obtained.

If you want to get ethyl acetate further, you must go through dehydration distillation.

Dehydration still uses a very simple distillation method.

Xiao Zirong originally thought that he could directly obtain aniline by making ethyl acetate today, but he did not expect that distilling alcohol would take part of the time, and dehydrating ethyl acetate would consume most of the time. After finishing everything, Xiao Zirong raised his head It was found that it was already sunset outside.

After thinking about it for a while, he prepared to leave work early, and save Aniline for tomorrow, or wait until his brother comes to arrest him himself.

His brother just celebrated his birthday, so it's better not to make him angry.

Xiao Zirong asked people to pour wine with not so high alcohol purity, simply put, wine with low alcohol content into a glass bottle.

The transparent bottle and the transparent wine look pleasing to the eye.

It's just that he's not too sure about the alcohol content, anyway, let's try some of it first.

When Xiao Zirong returned to the city lord's mansion with a bottle of wine, he happened to see his little wolf cub whimpering and whimpering around Xiao Xuexing, but Xiao Xuexing ruthlessly ignored it at all and let it groan Aww, Quan pretended not to see it.

Xiao Zirong went over and called out: "Xuexue."

However, the little wolf cub only gave him a back view, but Xiao Xuexing put down the book in his hand and looked at him.

Xiao Zirong was very annoyed at the wolf cub's double standard, and directly grabbed it by the back of the neck and grinned at it, "You dare to ignore your parents, I think you deserve a beating."

After he finished speaking, he saw that the little wolf cub's belly was bulging, as if he had just eaten.

He said with some confusion: "Don't tell me that I will feed you after dinner? Who fed it?"

The attendants in the courtyard all bowed their heads but refused to say anything, Xiao Zirong paused and turned his gaze to Xiao Xuexing.

Just as he was about to ask something, Xiao Xuexing calmly asked ahead of time: "Why did you come back so early today?"

"Huh?" Xiao Zirong paused before saying, "Oh, after reaching a certain stage, I looked at the sky and found that I came back early."

"Okay." Xiao Xuexing's expression looked a little regretful.

Xiao Zirong's hairs stood on end in an instant: "My intuition tells me that you probably didn't think of anything good."

Xiao Zirong didn't even look at him: "What nonsense, I'm ready for dinner."

After he left, Xiao Zirong just wanted to catch up when he heard the baby's voice, and looked down to see that the little wolf cub was still in his hand.

He was interrupted by Xiao Xuexing just now, and he forgot what he was going to ask just now.

Forget it, it's not an important matter anyway, Xiao Xuexing thinks he's upright, so he can feed him if he likes, as long as he doesn't die.

Xiao Zirong felt very considerate, so of course he didn't insist on exposing it.

Of course, the key point is what if Xiao Xuexing becomes angry after being exposed?

Xiao Zirong handed the little wolf cub to the slave who specially raised him, took the white wine and ran to Xiao Xuexing's side to present treasures and said, "Brother, come and taste this wine."

Xiao Xuexing was a little surprised when he saw the bottle in his hand: "Is this wine?"

Xiao Zirong raised his hand and shook it in front of him, and said, "How is it? Isn't it very beautiful?"

The transparent wine refracts different lights as it shakes, and it is indeed pleasing to the eye when paired with a beautiful bottle.

After Xiao Xuexing sat down, Xiao Zirong immediately asked someone to bring a set of glass wine cups.

Xiao Xuexing was a little surprised and asked: "When did you do it? Why haven't you seen it before?"

Xiao Zirong said: "It has been fired a long time ago, but I just thought the previous wine was too ugly, so I didn't use it."

The turbid wine has a certain artistic conception in an ordinary black porcelain cup, but it is simply revealed in a transparent wine set.

He got this wine set before and originally intended to use it with wine.

Well, let’s forget about the luminous cup or something. The high probability is that it is made of fluorite and has radiation, which is not as good-looking as glass.

Xiao Xuexing laughed and said, "You are really good-looking."

Xiao Zirong tilted his head and thought for a while, oh, Xiao Xuexing meant that he was lustful, but he said it more tactfully.

He stopped pretending in front of Xiao Xuexing, and said very confidently: "There's nothing wrong with liking good-looking people."

The corner of Xiao Xuexing's mouth twitched, it's too bad this is not his son, if his son has to deal with people well, how can he judge people by their appearance?

But in any case, this wine does look very good, and the taste is very strong. When you smell it, you will be refreshed: "Good wine."

Xiao Zirong shook his head proudly and said: "Of course, it's a pity that this is a new wine. If it is buried for 20 years, or even longer, it will become aged wine, and the taste will be great."

Xiao Xuexing held up the wine cup and shook his wrist lightly, and the liquid in the wine cup also swayed, it was truly beautiful.

After admiring it enough, he brought it to his mouth and took a sip. After this sip, his eyes lit up: "Come again."

After Xiao Zirong filled him up again, he handed the jug to Ah Yin who was beside him and said, "Put it away."

Xiao Xue paused, and looked up at Xiao Zirong with disbelief.

Xiao Zirong said calmly: "This thing is a bit irritating, your stomach is not healed yet, if it wasn't for the fact that this wine is newly made, it shouldn't be given to you."

Xiao Xuexing pursed his lips, regretting his illness for the first time, otherwise he would definitely drink more of such a good wine.

Seeing that he was a little unhappy, Xiao Zirong coaxed him and said, "Don't worry, these are all yours, no one will give them to you."

Xiao Xuexing was a little surprised: "Not for sale?"

Xiao Zirong hesitated for a moment and said: "Don't sell it, put it away, this thing has a more important function."

Xiao Xuexing asked casually: "Isn't it just wine, what effect can it have?"

Xiao Zirong said seriously: "Although it hurts to clean the wound with it, it is more likely that the slightly injured person will survive."

Xiao Xue paused, looked up at Xiao Zirong, her expression became very serious: "What are you talking about?"
