Bringing System to Great Tang

　　　　 When Li Yi made soap, during the saponification reaction, there was layering of salt and glycerin during the chemical reaction.

　　 there is an unsaturated saponification liquid in it. 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.

　　 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 don’t take a bath for a long time, especially in winter. Only officials have a day off.

　　 I want to say who always takes a bath, the girls in Pingkangfang, it is not unusual to wash eight times a day in Beiqu.

　　 The other is Zhuangzi who does hard work and special workshops. They cut their hair, short hair, and even men's hair.

　　 When you get to the bath, you can wash hard, which is convenient and comfortable.

　　 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, and don't worry about something falling into the patient's wound.

　　 "The oil is hard to find, especially the pancreas. Others use 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, the two things are much different, right?

　　 "It's like making soy milk into tofu." Li Yi understood the mind of the elder brother and explained it with the simplest example.

　　 "Yes, soy milk can be made into tofu, and can also be made into 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 talking, Li Yi asked the child who came over with his stomach: "Why are you uncomfortable?"

　　 "Belly, belly." The child said.

　　 "There are bugs, right? 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 hurts 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, it doesn't work, 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'.

　　 "I 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 the water quickly enters the kidneys into the bladder.

　　 A little bit of meat froth left, and the stomach gave feedback that the secretion of gastric acid increased, and the result was frothy.

　　 is still a bit bitter, right? 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 gives a scientific explanation, what bug? Just hungry.

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

　　 "Does it still hurt?" Li Yi asked again at this time.

　　 "It doesn't hurt anymore, it's warm." The child is honest.

　　 Li Chengqi was stunned next to him. He didn't feel hungry and uncomfortable. He was shocked by Li Yi's diagnosis.

　　 Press, the child spit out, and he knew he was hungry, even if he didn’t eat last night, he could tell?

　　 "Who else comes over to eat when hungry, eat less, and have lunch at noon, can my Lijiazhuangzi 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 of not eating?" Li Chengqi wanted to learn, but he didn't take it as a genius doctor just now.

　　 "It means drinking 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 stomach 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's too difficult, what's the mess?

　　 "What about now?" he asked.

　　 "Now I eat a few skewers to synthesize stomach acid, and then secrete more stomach acid. By noon, I can eat a lot of meals, not less than ordinary adults."

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

　　 "Yes, half a boy, eat poor old man." Li Chengqi came up with a saying.

　　 "Lord Li, don't we eat the same without money?" 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 I look at it, it is a process of learning, and sometimes I compare my pulse.

　　 When eating at noon, the children of the wealthy family went to Zhangjia Village, and the children who came by themselves were arranged in the corner of the cafeteria, and each person served a rice bowl with moss meat and shredded radish soup.

　　 The kids laughed~www.wuxiahere.com~ They thought there was only one bowl of noodles, and it would be nice to have a bowl of noodles.

　　 There are meat, eggs, fungus and cucumber slices, and the shredded radish soup is 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.

　　 "I will eat twice-cooked pork for them tomorrow, using garlic sprouts instead of chili, and I don't have chili for others to eat hard."

　　 Li Yi agrees with Ziyu's words and tells the diet arrangements for tomorrow.

　　 "The proprietors, I mean they are greedy." Ziyu regards herself as a member of Zhuangzi, and feels distressed for nothing.

"I didn’t dare to eat fat meat today, because I was afraid that they would not eat oil for a long time and would not adapt to the gastrointestinal tract. Mushu meat would just adjust. Tomorrow, eat fat and lean twice-cooked meat, plus garlic sprouts to stimulate the gastrointestinal tract, and eat braised pork cover the day after tomorrow. rice."

　　 Li Yi didn't seem to understand, or didn't hear what Ziyu said, so he continued to say his own.

　　 "The owner, I have finished eating, I will take care of the baby in Taohong." Cui Liu put down his chopsticks and said to go out.

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

　　 "I will tell them the proprietor in a while." Qing Song took the initiative to provoke important tasks to tell the four people about Zhuangzi.

　　 "It takes manpower to sell newspapers. If you don't have enough to raise your body, how can you go to various places to deliver newspapers." Li Yi said something that the four newcomers did not understand.

　　 His movable type has been produced, copper movable type.

　　 Lead type is not easy to take care of in winter and is easy to be poisoned, so I did not touch it. When the weather is warm, there are more protective measures, and then change.

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