Li Yi did not plan to directly draw the musket, and his smelting technology was not up to standard.

He now has nitroglycerin, which he made himself to treat cardiovascular diseases.

You can't change everything with the system, you can do it yourself to save your life.

What's more, the root problem of the Tang Dynasty is that its weapons are not good, and the Tang Dynasty's soldiers are still very capable of fighting.

There are now Modao Army who is moving towards the wall.

"I made that thing, and it made a crackling sound. If it flew into the sky, it could still blast and explode a gorgeous flower of light."

Li Yi introduced firecrackers and fireworks. He planned to set off salt and Glauber's salt. In high temperatures, the color can be changed.

Li Chengqi didn't know that what the person sitting in front of him did was a big killer weapon. He yearned for beautiful sparks.

"Brother Yi, if this is the case, you won't have to burn bamboo?" He likes to play.

"Saltpeter, put it together with other things, boom!" Li Yi introduced.

"Brother Wei knows, but the spark is not big, and there is no crackling noise. It's better to sprinkle salt when burning bamboo."

Li Chengqi said another kind of firecrackers, he could play with salt, and was rich and had status.

Of course, the production of firecrackers and fireworks consumes a lot of supplies.

"My this one is easy to use, but it needs to be operated in a standard way to avoid injury or water loss." Li Yi said another trouble.

For example, put the second kick and hold it horizontally, or hold it in your hand for the first sound, and then throw it out to listen to the second sound.

All those who have something wrong are people who think it’s okay.

"Brother Yi, do it, wait and play for me." Li Chengqi didn't want to know about technical matters.

After dinner, Li Chengqi was not in a hurry to go back and ran to the ice rink to learn ice skating.

Li Yi carried his hand to the workshop and found someone to make firecrackers.

There have always been saltpeter, charcoal and sulfur farms.

The purity is not enough and needs some purification. Others make paste to make a carrier for firecrackers.

An artificial paper rolling device and braiding device are needed. When filling the medicine, it is a bundle. Pour the medicine directly upwards and then smoothes it to proceed to the next step.

When making the medicine twist, it is directly weaved into the silk thread and inserted one by one.

It took half an hour to tell the process while drawing and the most important safety protection measures.

Move the firecracker workshop to the farthest location, and there are no buildings around it.

People who enter are not allowed to wear fur clothes, wear a hat on their heads, spray water on their oily clothes, and use metal rods to contact them to eliminate static electricity.

First find out the appropriate proportion of this batch, open it separately, and adjust it once when used.

Needless to say, the craftsmen understand everything about the fire, including cotton workshops, down workshops, wool workshops, woodworking workshops, papermaking workshops and other places, and everyone strictly abides by them.

Who doesn’t keep it? The first time I warn you, the second time I forget each other, and I won’t say goodbye.

So far, none of them have been driven out.

The merchants take the initiative to memorize the rules every day, and sometimes they are scared to wake up when dreaming of violating the rules and sweat.

They all understood that once they left the village, there would be nothing left, even if the boss said he would give some severance payment.

People who master the technology are even more worried about whether they can live to other places.

"It's almost like that. If you don't understand the details, don't try it yourself and ask me. Then our goal is..."

Speaking of this, Li Yi stopped.

The craftsmen shouted together: "Safety comes first, safety comes first, safety comes first."

"Very good." Li Yi left with satisfaction.

He went to the hospital building and gave Zhu Xie Jinshan an intravenous drip. It was time.

"Does it have fever?" Li Yi asked Zhu Xie, the son of Jinshan, Zhu Xie Fuguo.

"I just finished my meal and it was hot, thirty-eight degrees and seven degrees, and now it has reached thirty-eight degrees and two degrees again." Zhu Xie Fuguo was very clear about his father's affairs.

My father has given up his throne and is preparing to retire in Chang'an.

It is also good for him if his father lives for a long time, let alone who wants his father to die, is not fighting for a position, or if his father wants to kill him.

“Because the food I provided was steamed buns and rice, plus a lot of meat dishes, the calories themselves provided.

During the treatment process, it is not enough to supplement enough protein and fat, and it will accumulate calories after supplementing.

I have to grasp the balance throughout the process. The best thing is to eat mutton, and I am worried that I will make up too much."

Li Yi told the patient's family that his medication was also medicine for eating. His post-operative care in traditional Chinese medicine was well known abroad at that time.

Zhu Xie Fuguo listened carefully, which was also a kind of learning, and this was a miracle doctor.

Although I am not very old, I am not as good as the leader of the clan.

Li Yi was given an injection and listened to Zhu Xie Jinshan's breathing.

Instructed: "Continue to maintain a good mood. You see that the room is too dry. Spray a little water and let your father walk around appropriately. Watermelon, cucumber, and candied melon cannot stop."

"How many days will I be discharged from the hospital?" Zhu Xie Fuguo learned a new term in the inpatient department.

"In a few days, your father was in good health, just pneumonia, a minor problem." Li Yi's tone was emotional, giving the patient a motivation.

He believed that if he shook his head and sighed, he would come back to the evening and would ensure that he would burn to thirty-nine degrees.

He understood the patient's mood, and like the servant who had pulled his teeth before, he said it was very simple.

As a result, after the anesthetics, my teeth were extracted. The place where the tooth was extracted was recovered, and the place where the anesthetics was still swollen.

The servant is very resentful, but after he has pulled it out, what else can he do?

That one is a wisdom tooth, and it is not allowed to be inlaid, which makes Li Yi more regretful.

He likes to inlaid people. For every free inlaid, he thinks that he has made a lot of money.

People from the Imperial Physicians Department will, but the inlays are expensive and there is also mercury. If they leak, they will be medical accidents.

He made teeth, porcelain and his own equipment for the merchants and the elderly in the homes of forty-two students. He did not take them to the kiln to burn, but added silver and gold.

In the past, his dental clinics at that time didn’t buy porcelain equipment by themselves, which was too expensive. Usually, after seeing the patient, he took samples and went to a large porcelain tooth manufacturer to process it uniformly.

Very cheap, computer modeling, and then made in batches.

His equipment is small and requires some manual adjustments, so he is willing to do it.

After becoming proficient, it would be better to inlaid teeth for rich people in the Tang Dynasty. How could the teeth made by the Imperial Medical Office be better than those made by yourself?

Ordinary people from the Imperial Medical Department cannot find it, they are all dentist craftsmen on the market.

Some also use ivory or something, hard bones.

It is said that there are dead teeth, which Li Yi has never contacted.

Thinking about the inlay of teeth, Li Yi looked at Zhu Xie Jinshan's teeth. It was very good. At least three must be inlaid and three must be added.

There are two more that are worse than tonic. They are too crisp and difficult to wear up. They will wear away areas with not strong enough texture and may cause nerves to penetrate and draw nerves.

"The pneumonia will be cured in a few days. I will correct your teeth. If you think it's good, someone wants to inlay teeth in the future. If you bring it to Chang'an, I'll give it a little cheaper."

Li Yi told Zhu Xie Fuguo that he decided to put in effort to make good use of the old man's teeth and advertise.

"I still want money?" Zhu Xie Fuguo was stunned.

"How can you ask the doctor for money if you don't have money? Oh, your direct family doesn't want it. Others give you discounts and discounts, that's..."

"I know, takeout on heaven and earth will be discounted, I have a card." Zhu Xie Fuguo said that he understood.

"Oh, that's the case. I'll wash your teeth tomorrow, a big customer." Li Yi reached out and held Zhu Xie Fuguo's right hand and shook it.
