How tired is Li Zhan so tired these days? It’s just a round trip. While running around, he rushed to Dunhuafang and followed him to serve as a supervisor in the Tang Dynasty.

If you ask what this is for, what else can you do? Isn’t it because Li Zhan wants to prepare suture techniques and alcohol?

This suture technique is very simple. Li Zhan will use boiling water to steam the silk thread. These necessary measures are written on small notes and handed over to the imperial physicians.

After the imperial physician test, if it is established, it will be directly distributed among the military doctors, and finally the rural doctors.

You know, this is also a secret technique. At least Changsun Wuji thought so. He originally thought that Li Shimin would say something, and he really wanted Li Shimin to give Li Zhan a title.

But what disappointed Changsun Wuji was that Li Shimin not only did not grant Li Zhan a title, but did not even say that Li Zhan was a ancestral method offered by a Tang people.

Really, Changsun Wuji felt even more distressed about Li Zhan.

In addition to this suture technique, what makes Li Zhan even more busy is the method of alcohol.

Alcohol generally requires a degree of 75 degrees, and alcohol is widely used, not only for disinfection. This is also the reason why Li Zhan wants to make alcohol. As long as the alcohol is made, something that can make money will come into being.

The easiest way to make alcohol is distillation. As for the process, I will mention it all. I want to know Baidu, but this distillation is not simply just steaming directly.

To steam alcohol, two things that were difficult to make and never appeared during the Tang Dynasty.

The first difficult thing is iron pipe. The reason why this iron pipe is needed is to protect alcohol. Because in ancient times, open flames would definitely be used for distillation. During distillation, there would be ethanol. Everyone knows that ethanol is flammable and iron pipes must be long to prevent ethanol from getting close to open flames, so a long iron pipe is necessary.

The second thing that Datang does not have is the leather tube. The function of this leather tube is the same as that of an iron can, and it is also preventing flammability, because it must be installed at the connection port to prevent the steamed ethanol from evaporating.

If you use bamboo tubes and wooden tubes, it will be meaningless.

Li Zhanyou is the rubber tube tied to your arm when the nurse helps you to tick blood. There are still a few leather tubes in Li Zhan’s box, which can be considered as God’s eyes.

As for the iron pipes, there is really no one. What should I do? I can only go to the general manager of the Tang Dynasty to do it, how to do it? Make a very thin piece of iron sheet to roll it. This is a fine job.

So Li Zhan had to keep an eye on it, and worked day and night, and finally he made an iron pipe about one meter long. It was really difficult.

However, because it was too difficult, only Li Zhan could do this method of making alcohol, and no aristocratic family could imitate it. Li Shimin knew the importance of this matter, so he directly handed over the matter to Li Chengqian in full.

After all, Li Chengqian is the future emperor. As long as he masters this, the Tang Dynasty masters this.

"Down!"

Xiaodouzi stood in a room in Dunhuafang, directing other eunuchs to pour the imperial wine from the palace into a big pot. Why do you need to use imperial wine? Because the degree of imperial wine is higher.

While pouring wine inside, Li Chengqian sat outside with Li Zhan.

Although Li Zhan and Li Chengqian already knew each other's identities, Li Chengqian was still very respectful to Li Zhan and never had any disrespect to Li Zhan because of his identity as a prince.

This is because Li Chengqian relies on Li Zhan too much. I will not elaborate on it.

Li Chengqian was attentively pouring a cup of jasmine tea for Li Zhan and said with a smile: "Brother, thanks to you this time. Your father takes alcohol seriously, so let me help you. I don't even need to take classes in the East Palace. Haha, just follow you. Life is too fulfilling."

"Well, what are the things that are good at learning about those corrupt Confucian things? As long as you have the people in your heart, you will become a good emperor. If you don't have the people in your heart, just like Yang Guang, who is well-educated, but in the end, it will still be unpopular and replaced by the orthodox Tang Dynasty.

So Chengqian, you must remember that the most important thing is to have the people in your heart. As long as you have the people in your heart, you will be invincible."

"As for orders, brother!" Li Chengqian also poured himself a cup of jasmine tea and took a sip with a smile.

Following Li Chengqian, he looked at Li Zhan and asked, "Brother, this alcohol is really that great?"

"Of course!" Li Zhan leaned on the rocking chair and said, "Let me tell you this. In this time of our survival, there are actually many things called bacteria that we cannot see.

The thing is very small and cannot be seen with our eyes, but these bacteria are very powerful.

If you don’t apply some medicine to inhibit bacteria after the knife injury, your wound will become inflamed, ulcerated, and pus will flow. At this time, the invasion of bacteria will lead to much higher probability of death.

Alcohol is used to inhibit bacteria and kill bacteria. In this way, the bacteria are killed and the wound will not become inflamed, ulcerated, and pus will flow. Then the injured person will have a greater chance of survival."

"Oh, it's like this." Li Chengqian laughed and said, "Brother, you know so much. By the way, I want to ask my brother, what's wrong with you saying we can make money with alcohol?"

"Make money!" Li Zhan smiled and said, "That's an opportunity to make a lot of money!"

"It's more profitable than soap?" Li Chengqian looked at Li Zhan and asked.

"That's right!" Li Zhan said happily with a smile: "Soap and soap, wherever you go. As long as the alcohol is ready, I will start to study that thing. I almost forgot to ask for the materials you are looking for. Have you found it?"

"It's all simple things that I found. Not only did I find them, I also bought a lot of them according to your requirements, and I'm waiting for you to use them."

"Not bad!" Li Zhan expressed his moderate satisfaction with Li Chengqian.

At this moment, Xiao Douzi ran over and bowed to Li Zhan and said, "Young Master Li is already full, is it time to light the fire now?"

"Let Chengqian take some, the prince ignites the fire, and the credit for the alcohol will be given to the prince in the future."

Li Zhan's words made Li Chengqian stunned, and he followed Li Chengqian and said, "Brother, alcohol is yours. As long as the alcohol is recognized, then your contribution is enough to be awarded the title?"

Li Zhan laughed: "What kind of title do I want? I said, I won't be an official, that's all I don't need. I just want you to be good now. You are the prince. As long as you get better and better, I will rely on you in the future.

I believe you won't let me down, right?"

Looking at Li Zhan, Li Chengqian nodded vigorously and said, "Brother, don't worry, I, Li Chengqian, swear that I will protect my brother until my death in my life."

"Haha!" Looking at Li Chengqian, Li Zhan laughed and said, "Then it's over. Let's go and light the fire. We don't need to say anything else."

"Brother by your order!" Li Chengqian laughed!
