Li Zhan is very tired these days... How tired it is... It was simply a continuous rotation, while running the grass collection, while rushing to Dunhuafang, followed by the general who was going to Datang as a prisoner.

If you want to ask what this is for, what else can you do, isn't it because Li Zhan wants to prepare the suture technique and alcohol?

This suturing technique was very simple, Li Zhan wrote the essentials and the silk threads that had to be steamed in boiling water, and these necessary measures were written on a small notebook, and after being handed over, they were distributed among the imperial doctors.

Later, after the Taiyi test, if it is established, it will be directly distributed among the military doctors, and finally the township doctors.

You know, this is also a secret technique, at least the eldest grandson Wuji thinks so, he originally thought that Li Shimin would say something, and he really wanted Li Shimin to give Li Zhan a knighthood.

But to the disappointment of the eldest grandson Wuji, Li Shimin not only did not knight Li Zhan, but also did not even say Li Zhanlai, saying that it was an ancestral method offered by the people of the Tang Dynasty.

Really, the eldest grandson Wuji felt even more distressed about Li Zhan.

In addition to this suturing technique, what made Li Zhan even busier was the alcohol method.

Alcohol generally needs to be at 75 degrees... And alcohol has a wide range of uses, not only for disinfection, which is why Li Zhan wants to make alcohol, as long as the alcohol is made, something that can make money will also come into being.

And to make alcohol, the easiest way is distillation, as for the process, I will go through it, I want to know Baidu, however, this distillation is not simply direct steaming.

If you want to steam out the alcohol, you need two things that were difficult to make during the Tang Dynasty and never appeared at all.

The first difficult thing is the iron pipe, the reason why this iron pipe is needed is to protect the alcohol, because in ancient times, it would be distilled with an open flame, and when it was distilled, there would be ethanol, and everyone knew that ethanol was flammable, and the iron pipe must be long to prevent ethanol from approaching the open flame, so a long iron pipe is a must.

The second thing Datang does not have is the leather tube, which has the same function as the iron can, and is also to prevent flammability, because it must be installed at the connection port to prevent the evaporation of the evaporated ethanol.

If you use bamboo pipes, wooden pipes, it doesn't make sense.

Leather tube Li Zhan has... Even when the nurse helped you prick the blood, the rubber tube tied to your arm, Li Zhan still had a few in his box, which can be regarded as a long eye.

As for whether there is really no iron pipe, what to do ... I can only go to Datang's general as a supervisor to do it, how to do it, get a very thin piece of iron sheet to roll, this is a delicate job.

So Li Zhan had to keep an eye on it, day and night, and finally came up with an iron pipe about one meter long, which was really difficult.

However, because it is too difficult, Li Zhan's method of making alcohol can only be done by Li Zhan, and no family can imitate it, Li Shimin knows the importance of this matter, so he directly handed over this matter to Li Chengqian.

After all, Li Chengqian is the future emperor, as long as he masters this, it is the Tang Dynasty that has mastered this.

"Pour... Pour...! ”

Xiaodouzi stood in a room in Dunhuafang, commanding the other little eunuchs, and kept pouring the imperial wine in the palace into a large cauldron, why use the imperial wine, because the degree of the imperial wine is higher.

When pouring wine inside, Li Chengqian was sitting outside with Li Zhan.

Although Li Zhan and Li Chengqian already knew each other's identities, Li Chengqian was still respectful to Li Zhan, and never had any disrespect for Li Zhan because of his status as the crown prince.

This is because Li Chengqian's dependence on Li Zhan is not too much to repeat.

I saw Li Chengqian diligently pour Li Zhan a cup of jasmine tea and said with a smile: "Big brother... Thanks to you this time, your alcoholic father attaches great importance to it, so let me assist you, I don't even have to take classes in the East Palace, hehe... As long as I follow you, this life is too fulfilling. ”

"Hmm... What is there to learn about those rotten Confucianism, as long as you have the people in your heart, you will become a good emperor, if there are no people in your heart, just like Yang Guang, who is rich and rich, but in the end, it is still unpopular with the people and is replaced by my Tang orthodoxy.

Therefore, Chengqian, you must remember that having the people in your heart is the most important thing, and as long as you have the people in your heart, you will be invincible. ”

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

Then Li Chengqian looked at Li Zhan and asked, "Big brother... Is this really that good alcohol? ”

"Of course...!" Li Zhan leaned back in the rocking chair and said, "Let me tell you this, at this time of our existence, there are actually many things called bacteria that we can't see.

It's so small that we can't see it with our eyes, but these bacteria are powerful.

If you don't get a little medicine to inhibit bacteria after the knife wound, then your wound will become inflamed, ulcerate, and pus, at this time, it is the invasion of bacteria, and the probability of death will be much higher.

And alcohol is used to inhibit bacteria and kill bacteria, in this way, the bacteria are killed, and then the wound will not become inflamed, ulcerate, and pus, then the injured person, the chance of survival will be greater. ”

"Oh... That's what it looks like... Li Chengqian smiled and said, "Big brother... You know so much, right... I also want to ask my eldest brother, what is the matter with you saying that we can make money with alcohol? ”

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

"More money than soap and soap?" Li Chengqian looked at Li Zhan and asked.

"That's right...!" Li Zhan smiled happily and said: "Soap and soap, that's where it goes, as long as the alcohol is ready, I will start researching that thing... Yes... I almost forgot the material I was looking for, did you find it? ”

"Found it... It's all simple things, not only did I find them, but I also bought a lot of them according to your requirements, just waiting for you to use them. ”

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

At this time, Xiaodouzi ran over, bowed to Li Zhan and said, "Li Gongzi... It's already full... Is it time to ignite. ”

"Let Cheng Qian go and light the fire, and the credit for this alcohol will be the prince's in the future."

Li Zhan's words made Li Chengqian stunned, and followed Li Chengqian: "Big brother... The alcohol is yours, as long as the alcohol is recognized, then your merit is enough to be knighted, big brother? ”

Li Zhan laughed: "What title do I want, I said, I won't be an official, that's what 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'm sure you won't let me down, right? ”

Looking at Li Zhan, Li Chengqian nodded vigorously and said, "Big brother... You can rest assured, I, Li Chengqian, swear that I will protect my eldest brother for the rest of my life until death. ”

"Haha...!" Looking at Li Chengqian, Li Zhan laughed and said, "Isn't that over, okay... Go light the fire, we don't need to say anything else between us. ”

"Yes... Eldest brother...! Li Chengqian laughed!
