"There really is another way. I also wrote that the ghost doctor scrubbed Ji Zheng's limbs clean with spirits, and he did this to reduce the number of bugs attached to his skin.

In other words, spirits can actually kill insects, but the effect is not as good as high temperatures. ”

"So spirits can also be used, that's great, that's great." Lu Jing trembled with excitement.

Chi Fei shook his head and said, "You think too simply, the spirits you think about are different from the spirits mentioned in the book.

Spirits that can really kill insects must at least be ignited, otherwise they will have little effect. ”

"Wine can ignite?" It was the first time Lu Jing had heard such a statement.

"That's why I said that the spirits you think of are not the same as the spirits you talk about in the book. When the purity of the wine is high enough, it can indeed be ignited.

However, if you want to get this kind of high-purity spirit, you can't make it by conventional methods. It must be purified by a special method to be possible. This is one of the difficulties that makes it impossible to administer this treatment. ”

"Are there any other difficulties in that?"

"Yes, the second difficulty is anesthetics. When a person's wound begins to suppurate and fester, or is stained with poisonous things, it is necessary to remove the purulent area or the poisoned part, and then suture it to make it possible to heal.

But can you imagine how much pain the patient has when performing this surgery? That's not something ordinary people can bear, it's really cutting flesh alive with a knife. If there were no anesthetics, the pain alone would have been painful.

The reason why the ghost doctor dares to use the knife on a living person is because he has a unique anesthetic that can make people fall into a coma without any consciousness. But that's just the storyline, I don't have such an anesthetic prescription. ”

The more Lu Jing listened, the colder his heart became. He is a professional doctor, and he knows that what Chi Fei said is indeed the truth as soon as he hears it.

In the past, when he helped wounded soldiers amputate their limbs, he needed to tie people tightly to the pillars, and then ask the powerful soldiers to cut off the injured limbs with a knife in their hands, and then use a red-hot soldering iron to burn the wounds alive to stop the bleeding, and finally bandaged.

The pain was so intense that no one could bear, and some even died in the midst of it.

If you use the kind of treatment surgery that Chi Fei said, it is indeed cutting the flesh of a living person, and the pain is also very fatal.

After thinking for a while, Lu Jing said: "Sir, as for anesthetics, I am actually studying them.

Because I often have to amputate the limbs of wounded soldiers, I also wanted to develop a medicine that would relieve their pain.

But how to extract this high-purity spirit, do you really have no choice? ”

"There is a way, but I have never tried it myself, but I only have a rough idea of the principle."

Lu Jing was overjoyed when he heard this, "As long as you know the method, I'll go back and test it myself."

Mr. Wanwang can tell me, please, please. At the end of the day, he simply knelt down.

Chi Fei hurriedly pulled him up, "Doctor Lu, don't be like this, I can't afford such a big gift." Wait a minute, I'll draw the drawings. ”

With that, he walked over to his desk, picked up a brush, and drew on paper.

Although the brush is far less useful than the charcoal pen, Chi Fei still tries to draw as finely as possible.

A few minutes later, he handed the drawing to Lu Jing, "This is the appliance used to extract high-purity spirits, this is called a still, and the extraction method is called distillation." ”

Lu Jing was a little surprised and said, "Distillation method? According to the history books, this is a secret method of sake brewing that has been lost for many years. ”

His words solved a question that Chi Fei had always had: why did this ancient society, which was very similar to the Ming Dynasty, have no distilled spirits.

In his world, since the Yuan Dynasty, there have been records of distilled spirits and stills in the literature, so distilled spirits have appeared very early in ancient times. But it didn't appear here, so Chi Fei felt a little disobedient.

Now listening to Lu Jing say this, it seems that this distillation method is not nothing, but lost.

Chi Fei speculated that distilled spirits had indeed appeared in this world before, but due to the war, this technology was lost. If so, it makes sense.

Regarding this still, it was actually found by Chi Fei when he was writing novels on the Internet before, but he only roughly knew the principle and structure, and he didn't try it, it was completely on paper.

So even he didn't know if this drawing, which was drawn entirely from memory, could make a real working still.

Lu Jing was even more confused than him, and he didn't understand what was going on with this still after looking at the drawings for a long time, so he asked him about the specific structure.

Chi Fei pointed to the drawings and explained: "This sealed barrel is called a retort barrel, which is used to store wine.

Do not exceed two-thirds of the retort barrel capacity, otherwise it is easy to overflow when steaming.

Underneath it is a bottom pot for heating over a fire.

This very long tube is called a steam pipe and is used to transport steam to the cooling dish.

The biggest thing is the cooling dish, which cools down the heated steam into a higher purity wine.

This small hole is the spout, and what flows out of it is the finished product.

The whole still works like this: first, a fire is lit in a bottom pot, and the wine in the retort barrel is boiled until it boils, allowing it to produce a large amount of steam. The vapors are transported to the cooling dish through this pipe. As the temperature of the steam decreases, it becomes a higher purity wine, which then flows through the outlet to the outside barrel.

These principles may be difficult for you to understand at first, but once you have tried them yourself, you will naturally know what is going on. ”

Lu Jing frowned and looked at it for a long time, and asked, "Sir, I can barely understand the part of steaming, but I really don't understand how this cooling dish cools down the steam." ”

"This cooling dish is mainly composed of two parts, one is the inner tank for storing steam, and the other is the outer water reservoir. Wait a minute, I've come up with a better example. ”

Chi Fei walked quickly to the kitchen in a flash of inspiration, found a large soup bowl, filled it with water, and carried it back to the living room.

He put his teacup in the soup bowl and explained, "See, this cup of tea was originally hot, but soak it in cold water, and soon it will cool down."

The hot tea in the cup is not in direct contact with the cold water outside, and although they are separated from the cup, it does not affect its cooling effect.

The principle of this cooling dish is very similar to it, steam is equivalent to hot tea, the inner tank is the cup, and the water reservoir is the soup bowl filled with cold water.

The water reservoir is filled with a constant flow of cold water, which cools the steam inside through the inner tank, turning the steam inside into water, which then flows through the outlet to the outside barrel. That's probably how it works, do you see it? ”

After this example, Lu Jing finally understood seven or eight points. Although there are still some unclear points, at least it is not as confusing as before.

Chi Fei said to him: "Actually, I only know the principle and structure of this distiller, I have never seen the real thing, let alone made it, so I am not sure whether I can make a finished product from this drawing."

But the method is correct, and through continuous distillation, it is indeed possible to extract high-purity spirits.

Of course, in order to extract a spirit that can be ignited, it is not enough to distill it once or twice, it needs to be distilled many times.

It is quite possible that a few liters of wine can only extract one glass of such a spirit, and the conditions are very harsh.

However, as long as it can be successfully extracted, it can indeed be an effective medicine to prevent infection. ”

"As long as there is a way, if it doesn't work once, try the second, third, and fourth times, no matter how many times I try, I will definitely make it." Lu Jing was like a treasure, and carefully held the drawings in his hand.

Chi Fei thought for a while and said, "Even if you can successfully make a still, how many high-purity spirits can you extract on your own?"

One of my advice to you, when you've made the still, you sell the method and the drawings of the still to as many wine merchants as possible and let them do it for you. ”

"I don't really understand what you mean, sir."

"Quite simply, high-purity spirits are absolutely the best for many alcoholics.

Once the wine merchants know about this purification method, they will definitely use it in large quantities to make high-purity spirits and sell them at a high price.

Merchants are very profitable, and it is believed that it will not be long before high-purity spirits like this will appear on the market.

At that time, you only need to convince your commanders to buy this liquor in large quantities as a munition, and there will be enough disinfectant. By the way, you can also use this method to make a fortune. ”

"Sir, your idea is wonderful. However, you came up with this method, even if you want to sell it for money, you will sell it, and you don't dare to be greedy for this money. ”

Chi Fei looked at him and said, "I'm not short of money, I told you these treatment methods and purification methods because I saw that you were really thinking about the wounded soldiers."

I hope you don't forget your original intention and always remember why you are here today. ”

Lu Jing saluted very solemnly and said: "Sir, don't worry, Lu Jing swears here, if what I have heard and learned today is not used in the wounded soldiers, then I will be thundered and thundered in the sky, and I will not die well." ”

"Don't say I didn't remind you, these treatments are so shocking that if someone dies during treatment, it's natural for someone else to put the blame on you.

You're likely to end up ruined and betrayed, so I didn't want to tell you the truth in the first place. You have to think about it. ”

Lu Jing said with a firm expression: "As long as you can use this method to save one person, even if you are spurned by everyone, you think it's worth it." ”

"The path is yours to choose, and I hope you can succeed.

I still say the same thing, everything I said today, once I get out of this door, I will not admit it.

I'm not like you, I'm just a selfish life-saving person. ”

Lu Jing said with red eyes: "If people like Mr. are also selfish, then there will be no good people in the world." ”

Chi Fei smiled noncommittally.

Next, Chi Fei told him all the modern hygiene knowledge he knew about how to prevent wound infections and how to disinfect with high-purity spirits.

As for how to stitch up the wound, Chi Fei only knew that there was such a thing, but he had not done it himself.

So Chi Fei asked Lu Jing to buy some pork to practice after he went back, and he really couldn't help in this regard.

Just remind him that the needles and threads used for sutures must be thoroughly boiled in boiling water before they can be used, otherwise there is a risk of wound infection.

Lu Jing was afraid that he would miss it, so he took the pen and wrote it down one by one very seriously.
