Bring The System To Datang

Chapter 216

When Li Yi made soap, salt and glycerin were layered during the chemical reaction during the saponification reaction.

There is the liquid of the unsaturated saponification reaction. The salt and glycerin are extracted separately, and the rest is soapy water.

These soapy waters are generally used to participate in the next saponification reaction. If you want to purify, you can still produce some soap, but the input is not proportional to the output.

Now it happens to be sold out, and the entire Datang Li Yi can’t take care of it. Chang’an County is still okay.

There are more than one million people, not all of them use soapy water and soap powder, and the poor use plant ash to scrub.

That is, the people of Datang do not take a bath for a long time, especially in winter, only officials have a day off.

It is not uncommon for the girls in Pingkangfang to wash eight times a day in Beiqu.

In addition, the villagers who do hard work and special workshops in Zhuangzi have cut their hair, short hair, and even men’s hair.

It is convenient and comfortable to wash hard when you get to the bath.

If Li Yi didn’t take care of Face, he would like to shave a bald head. It is convenient for bald heads to be operated on. Wash it and put on a surgical cap, so he doesn’t worry about something falling into the patient’s wound.

“The oil is hard to find, especially the pancreas. Others have used it to wash things with plant ash.” Li Chengqi knew that Li Yi had used a lot of fat before.

“I use soybean oil now.” Li Yi whispered, who stipulated that the saponification reaction must be animal fat?

“Soybean oil is also acceptable?” Li Chengqi was surprised. He never learned to use soybean oil to make soap since he was a child. How many magical things are there?

Oil and soap are very different, right?

“It’s like making soy milk into tofu.” Li Yi understood Dage’s mind and explained it with the simplest example.

“Yes, soy milk can be made into tofu or dried tofu, and soap also puts gypsum, brine or vinegar in soy oil?” Li Chengqi began to imagine.

“If you put vinegar, the cooked oil can be used to mix vegetables.” Li Yi joked.

After speaking, Li Yi asked the child who came over with his stomach: “Why are you uncomfortable?”

“Belly, belly.” The child said.

“Is there a bug? Brother Yi, you give him that candy.” Li Chengqi felt that he could be a doctor.

Li Yi asked Qing Song to lay the box flat, the child put it on, and began to touch and press.

“Does it hurt here?” Li Yi asked.

“It hurts when you press it, but it doesn’t hurt if you don’t press it.” The child replied.

“Why does it hurt, is it like a needle stick?” Li Yi asked again.

“It hurts when pressed, it hurts everywhere.”

“What about here?”

“It doesn’t hurt, no more, I want to spit.” The child struggled as he said, wow! Spit.

“Can I vomit again?” Li Yi asked when he looked at the vomiting’water’.

“Can’t spit it out,” the child replied.

“Give him two skewers, hungry.” Li Yi ordered.

Ask the child again: “Didn’t eat last night?”

“How do you know?” The child said I was surprised.

“Not only did I not eat, but I didn’t drink a few sips of water. I went straight to Zhuangzi in the morning and drank a few sips of soup. My body needs a lot, and your skating bike exercises a lot.

The metabolism is too fast, and water quickly enters the kidneys into the bladder.

The remaining bit of frothed meat will give feedback from the stomach, and the secretion of gastric acid will increase. As a result, the spit out will be frothy.

Isn’t it a bit bitter? Gallbladder is involved in the secretion. There is bile in it. Gastric acid stimulates the gastric mucosa. Of course, you have a stomachache. ”

Li Yi gave a scientific explanation, what bug? Just hungry.

The dealer next to them gave a few skewers, and the child ate them beautifully.

“Does it still hurt?” Li Yi asked at this time.

“It doesn’t hurt, it’s warm.” The child is honest.

Li Chengqi was stunned beside him. He didn’t feel hungry and uncomfortable. He was shocked by Li Yi’s diagnosis.

Press one button and the child will spit out and know that he is hungry. Can he even tell if he didn’t eat last night?

“Who else is hungry and eats less. I have lunch at noon. Can my Li Family Chuangzi give the children a bite?”

Li Yi shouted at the other children.

Sure enough, many children came back and wanted to eat.

“Is it because I didn’t eat?” Li Chengqi wanted to learn, but he didn’t take it as a genius doctor just now.

“It’s soup. If you don’t drink soup, it’s okay. There is oil and water in the soup, and the stomach will naturally absorb it. Otherwise, it will be too hungry. If the stomach finds itself empty, it slows down the secretion of stomach acid, so you don’t feel hungry.”

Li Yi explained the reason, hunger is the feedback of gastric acid irritating the gastric mucosa.

I don’t feel hungry for a while after drinking a lot of water because the water dilutes stomach acid.

Li Chengqi: “…”

He feels that he is not suitable for studying medicine, at least not suitable for studying medicine with Brother Yi. It is too difficult, what’s the mess?

“What about now?” he asked.

“Now eat a few skewers to synthesize gastric acid, and then secrete more gastric acid. By noon, you can eat a lot of meals, not less than ordinary adults eat.”

Li Yi went to scoop a spoonful of soup and drank it. It was cold outside.

“Yes, half a child, eat poor daddy.” Li Chengqi came to the saying.

“Dongzhu Li, don’t we need money for food?” A man from a wealthy family came over and said to Li Yi.

“Are you embarrassed?” Li Chengqi went back.

After saying this, Li Chengqi hurriedly left. Should the game be over there? It’s time for the next game, and then eat.

Li Yi also did not answer these boring questions, and continued to look at the child’s physical condition.

When you look at it, it is a process of learning, and sometimes you can compare the pulse.

When eating at noon, the children of the wealthy family went to Zhangjia Village, and the children who came by themselves were arranged to the corner of the canteen, each with a bowl of musu meat and shredded radish soup.

The children laughed. They thought that there was only one bowl of noodles. It would be nice to have a bowl of noodles.

It turned out that there were meat, eggs, fungus and cucumber slices, and shredded radish soup was also delicious.

So they decided to come back tomorrow and call other friends.

“Proprietor, they will be coming tomorrow.” Ziyu said something in line with human nature.

“Tomorrow I will give them twice-cooked pork, using garlic sprouts instead of chili, and I don’t have chili for others to eat hard.”

Li Yi agreed with Ziyu’s words and stated the diet arrangements for tomorrow.

“The proprietor, I mean they are greedy.” Ziyu regards herself as a member of Zhuangzi and feels distressed about giving things to others in vain.

“I didn’t dare to eat fat meat today, because I was afraid that they would not eat oil for a long time, and the gastrointestinal tract would not adapt. Mushu meat just adjusted. Tomorrow, they will eat fat and thin twice-cooked meat, plus garlic sprouts to stimulate the gastrointestinal tract. Rice.”

Li Yi seemed to have not understood or heard what Ziyu said, so he continued to say own.

“The proprietor, I have finished eating, I will take over Taohong to take care of the baby.” Cui Liu put down his chopsticks and said to go out.

“I’m done too.” Brown Rock pulled the last bite of food into his mouth, and said in a vague voice, he hadn’t swallowed it yet.

“The proprietor will tell them in a while.” Qingsong took the initiative to provoke important tasks and told the four people about Zhuangzi.

“It takes manpower to sell newspapers. If you don’t feed it, how can you go to various places to deliver newspapers?” Li Yi said something that the four newcomers didn’t understand.

His movable type has been made, copper movable type.

Lead type is not easy to take care of in winter, and it is easy to be poisoned.

Each movable type is money, which is made by melting copper coins and ordinary copperware.
