The pretty widow is addicted to money, and the little wolfdog asks for a hug

Gu Qinghuai glanced at his unfinished shoes and said with a smile, "Sorry, Doctor He, I was busy building a house some time ago. That's why I came just now. These are my two sisters, Gu Qingya and Gu Qingmiao, whom you have met. Come, Yaya, Miaomiao, meet your senior brother."

Big Brother?!

Doctor He's face flashed with embarrassment, but he still smiled and said hello: "Uh, ok, Junior Master... Hello, Junior Sisters."

Although the master has not yet agreed to accept the two little girls as disciples, he believes that as long as the master hears about Madam Gu's technique for suturing external injuries, he will definitely agree.

"Hello, Senior Brother!" Gu Qingmiao took Gu Qingya's hand and called out crisply according to Gu Qinghuai's instructions.

"Oh, okay," Doctor He agreed with a smile, and said to Gu Qinghuai enthusiastically, "Mrs. Gu wants to see you, let's go inside and talk in detail!"

Gu Qinghuai stood still. She looked at Doctor He and said directly, "Doctor He, I made it very clear last time. As long as Doctor Lin agrees to take my two sisters as his apprentices, I will tell you everything I know about wound suturing."

Doctor He took a deep breath and said firmly, "Don't worry, Madam Gu. My master is obsessed with medicine. As long as he hears your wound suturing skills, he will definitely agree."

Gu Qingsong tilted his head and said, "Doctor He, if my third sister tells you about the suturing technique and you change your mind, what should we do?"

"They dare not. If they go back on their word, I will smash Huichun Hall and chop off both of their hands!" Qi Yuanshuo stared at Doctor He and said coldly.

Doctor He shuddered, looked up at Qi Yuanshuo, and said with a smile: "Little brother, my master and I are both trustworthy people. The situation you described will never happen."

"You'd better do so," Qi Yuanshuo said.

Xiaohuo looked calm: "Uncle, Uncle Xiaosong, you don't have to worry. Aunt Huaishu will definitely find a way to make them agree."

Gu Qinghuai smiled and touched Xiaohuo's head, and said to Doctor He: "Let's go to the inner room and talk in detail."

"Hey, hey!" Doctor He immediately made a "please" gesture.

Just as everyone sat down in the spacious reception room, Doctor Lin walked in with his hair loose and yawning.

He looked sleepy and was in a bad mood when he woke up.

Dr. Lin

After entering the room, Doctor Lin slightly raised his eyelids, glanced at Gu Qinghuai and the others, and snorted coldly: "Madam Gu, you are so arrogant that you even dare to disturb my nap."

This old man is quite arrogant. If he wasn't interested in the art of suturing external injuries, he probably wouldn't have come here at all.

"Sorry to bother you, Doctor Lin," Gu Qinghuai bowed respectfully to Doctor Lin.

"Hmph!" Doctor Lin raised his chin, turned his shoulders and looked away.

Gu Qinghuai pretended not to notice his awkwardness, and directly pushed Gu Qingya and Gu Qingmiao to the front, and said in a serious tone: "Doctor Lin, these are my two sisters, Gu Qingya and Gu Qingmiao, one is eight years old and the other is five years old. I want them to worship you as their master and learn medical skills from you. Of course, I will exchange my wound suturing skills with you, and you will definitely feel that it is worth it."

Doctor Lin yawned and said nonchalantly, "Okay, tell me about it. If the suturing technique can really impress me, I will consider taking them as my apprentices."

Doctor He was very happy to see his master's promise. He stood up and poured tea and water himself, being particularly attentive.

After pouring the tea, he asked Sanqi to bring the four treasures of the study, then closed the doors and windows, sat upright at the wooden table, holding a brush in one hand and a blank book in the other, looking at Gu Qinghuai expectantly.

Qi Yuanshuo knew that Doctor He was only devoted to his medical skills and did not have any improper thoughts about Gu Qinghuai, so he felt a little relieved.

However, just because there is no chance of it now doesn't mean there won't be any chance of it in the future. After all, Sister Xiao Huai is too charming, and he still can't take it lightly.

Gu Qinghuai said softly: "There are many types of wound suturing techniques. I will talk about the most basic ones first. The first step in treating wounds is disinfection."

"What is disinfection? How can there be disinfection if there is no poisoning?" Doctor He was like a primary school student with a strong desire for knowledge. He opened his eyes wide and stared at Gu Qinghuai intently, afraid of missing a word.

Doctor Lin stopped yawning suddenly and his ears stood up.

Gu Qinghuai glanced at Qi Yuanshuo beside him, and seeing that he was looking at him with shining eyes, he straightened his back and said, "This poison is not that poison. The "poison" I am talking about is also called bacteria and viruses, which are microorganisms that cannot be seen by the naked eye.

They are everywhere and at all times. For example, the decomposition of corpses, the rottenness of food, and the infection and inflammation of wounds are all caused by them.

Before treating a wound, the doctor should wash his hands with soap; various medical instruments should be either boiled in water or disinfected directly with disinfectant or alcohol; wounds should be disinfected with disinfectant or saline or alcohol. Disinfection will kill bacteria and reduce the chance of ulceration. "

[Ding, congratulations to the host for receiving the male admiration points, total points]

Gu Qinghuai smiled and glanced at Qi Yuanshuo, and Qi Yuanshuo's heart began to beat fast when he saw her look.

[Ding, congratulations to the host for receiving 5000 points of male admiration, total points]

Doctor He's eyes were dazzling. "Madam Gu, the soaps you mentioned are the two bars you gave me, right? They are really useful. What are the disinfectant, saline solution, and alcohol?"

Gu Qinghuai nodded: "Yes, what I gave you is soap. Washing your hands frequently with soap can remove bacteria and viruses on your hands and prevent diseases from entering your body through your mouth.

Disinfectant is a medicine, which is currently very difficult to make; alcohol is made by purifying wine to make the alcohol content reach a high value; physiological saline is water made of salt and water in a certain proportion, which is most suitable for the human body. "

Gu Qinghuai is not convenient to explain some modern terms and can only be used ambiguously.

Doctor He was concentrating on taking notes.

Doctor Lin narrowed his eyes, looked at Gu Qinghuai dimly and said, "Madam Gu, you are really good at bluffing. You said viruses and bacteria, these microorganisms are invisible to the naked eye, so how do you know they exist?"

Doctor He was startled. "Yes, Madam Gu, how do you know they exist?"

Qi Yuanshuo and the other four kids also looked at Gu Qinghuai in amazement.

They also wanted to ask this question, but they couldn't expose Sister Xiaohuai (Aunt Huaishu) in front of outsiders, so they held back and didn't ask.

Gu Qinghuai had anticipated this question long ago, and she said calmly: "I have read relevant records in a very rare travel notebook, which said that foreigners on the other side of the ocean invented something called a 'microscope' that can see microorganisms.

At the time, I was very shocked and I verified it in various ways in my daily life.

For example, if I heat up a bowl of leftover rice in a pot every day, it will not go bad easily, but if I don’t heat it at high temperature, it will go bad quickly.

This shows that there must be invisible microorganisms in the leftovers. High-temperature heating can kill them. Without them, the food will not easily deteriorate.

For example, meat marinated with salt can be preserved longer than fresh meat. Many people know this, but they don’t understand the principle behind it, because salt kills microorganisms and prevents meat from spoiling.

For example, some people like to use a soldering iron to burn the wound, so that the wound will not easily fester, and this is because the high temperature kills the bacteria in the wound.

Food spoils more easily in the summer when the temperature is high than in the winter because bacteria are more active in the summer, while bacteria are more likely to be frozen to death in the winter. However, no matter how high the temperature in the summer is, it cannot kill bacteria. Only when it reaches the temperature of boiling water can it kill them.

After Gu Qinghuai finished speaking, she found that the room was very quiet. Everyone was motionless, staring at her blankly, all of them looking fascinated by what she was saying.
