Regarding Zhang Sijiu's question, Gu Qingzhou looked at the sky and showed a sense of helplessness: "It's only been more than seventy, eighty or ninety years." I'm so old after all - who knows when? ”

Zhang Sijiu's forehead jumped with green tendons: "So what kind of disease do you have?" ”

Gu Qingzhou coughed, looked left and right, but didn't dare to look at Zhang Sijiu: "Old and sick." When people are old, they are old and sick! ”

Zhang Sijiu turned his head and left: This old man!

However, although Gu Qingzhou is a little unreliable, he really teaches Zhang Sijiu. Basically, even the daily focus is on Professor Zhang Sijiu.

It's just that after a period of time, he expressed his disapproval of Zhang Sijiu's previous behavior of learning everything: "People's energy is never limited, and only by specializing in one thing can you achieve something." Everywhere is grasped, and in the end everywhere is not proficient, just take a erudition. ”

Zhang Sijiu was stunned for a moment, and asked Gu Qingzhou: "But if you can't prescribe medicine and take the pulse, how can you heal people?" ”

Gu Qingzhou sighed: "The Yellow Emperor's internal scripture says, those who are superior cure diseases, those who are intermediate are cured of minor diseases, and those who are inferior are cured of major diseases. Not really. It would be best if you could condition your body from the beginning so that it would not get sick. But most people in the world do not know how to prevent and treat diseases, even minor diseases. When people need medical treatment, they often become seriously ill. ”

"What you and I have to take care of is this kind of serious illness and disease, you can't live unless you don't go to the lesion, you can't live if you don't use the sword! Since we're in charge of this, what do we learn from that? As long as you can see what is wrong, as long as you know how to cut it, how to sew it, and what medicine to take afterwards to save your life! As for conditioning the body—that's another doctor's business. ”

Gu Qingzhou looked at Zhang Sijiu with a burning look: "Do you know, why am I the only one who has learned this subject?" How many uncles do you have, but they all learn other general medical skills? ”

Zhang Sijiu subconsciously asked: "Why?" ”

Gu Qingzhou raised his hand: "Because of these hands." Not everyone can learn this craft. It seems that the knife is light and fluttering, but only those who really hold it can understand how heavy this knife is. How heavy is each knife here? ”

As a surgeon, Zhang Sijiu understands the meaning of these words better than anyone else.

The scalpel tests a person's heart, a person's physical fitness, and ...... Talent.

If a person's psychological quality is not strong enough, it is difficult to do a good job in delicate surgery.

The more major the surgery, the more challenging it is.

If you are not mentally stable, you will probably injure nerves and break blood vessels as long as your hand shakes during surgery, which is the most terrible thing in surgery.

Moreover, not everyone can gradually adapt to the bloody scenes after seeing too many bloody scenes.

More people will become more and more resistant, and the psychological pressure will increase dramatically, and in such a state, they will not be able to get on the operating table.

Zhang Sijiu looked down at his hands, then at Gu Qingzhou, and finally nodded: "I listen to Master." ”

After this conversation, Gu Qingzhou completely changed his teaching routine.

At the same time, Gu Qingzhou was also quickly accepting Zhang Sijiu's set - such as salt water rinsing, such as alcohol sanitizing, such as fumigation and drying gauze.

Zhang Sijiu was also opened to a new world by Gu Qingzhou: the dirt that cannot be cleaned well by salt water flushing can be used as a rinsing material with slightly thickened wort - the original intestinal anastomosis operation, the inner wall of the abdominal cavity was washed with boiled barley soup.

At the same time, Gu Qingzhou also smeared the suture with fresh chicken blood to achieve the effect of sealing.

The reason why this effect can be achieved is actually very simple: the blood clotting speed is very fast, and after the chicken blood coagulated on the suture mouth, it can block the small gap of the suture mouth and prevent bleeding from leaking into the abdominal cavity, and at the same time, the contents of the intestines can not seep out and pollute the abdominal cavity!

You must know that once the peritoneum is infected, it will cause an acute abdomen, which will also kill people.

As for the sutures, the wisdom of the ancients was also extraordinarily powerful.

Animal protein threads are very easy to trigger allergies and rejection reactions. Especially the rough-made fish intestines that Zhang Sijiu is using now.

So, the ancient people used mulberry bark to make threads.

When dry, it is very light and easy to store, when used, only need to be boiled with water a little, the mulberry thread is soft, and it is very flexible, and even in the later stage, it can be absorbed-

Gu Qingzhou took Zhang Sijiu to make a mulberry thread, and the process was really cumbersome, from taking the skin, beating the skin, soaking in water, drawing the thread, and processing......

It took a whole month to make that little bit of finished suture.

But after trying the effect on animals, Zhang Sijiu was surprised to find that it was indeed very easy to use-

At this moment, Zhang Sijiu's only feeling was: It's a pity. It's a shame. Why hasn't such a good thing been passed on?

Looking at Zhang Sijiu's dirty buns, Gu Qingzhou finally felt proud: "Look, my master didn't serve you in vain, right?" Little girl, learn carefully. Your master and I still have a lot of skills! ”

Zhang Sijiu was convinced: "The things left by the ancestors are really amazing, and they should be passed on." ”

Time flies in the study of medicine and R&D.

During the autumn harvest, before he had time to verify the efficiency of the improved harvester, Yang Yuanding came to Zhang Sijiu to say goodbye.

Yang Yuanding sighed: "My grandfather is not in good health, we all have to rush back." This time, it is estimated that it will not come again. Even my father will have to worry about it for three years. ”

The news came too suddenly, and Zhang Sijiu was a little stunned: "Your family is leaving Mianzhu County?" ”

Although Zhang Sijiu and Yang Yuanding were mentally prepared for this matter, when this moment came, everyone's hearts felt a little too sudden and too fast.

There's a lot they don't have to do.

Penicillin hasn't been made until now, and the oil mill has opened, but the oil yield has not been able to go up, and the raw materials are too little-

Yang Yuanding nodded with a bitter face: "After leaving, I guess I will be pressed to study, and when the time comes, I will definitely not be as comfortable as I am now." And I don't know if it's going to be exposed—"

Zhang Sijiu was not so worried about this matter: "Don't be afraid, when the time comes, be smart, and pretend to be sick when you see that the situation is not right." Just pretend you don't remember. Anyway, you almost died when you fell into the water, and it is reasonable that you will not be able to shine in the water in your head. ”

As soon as Yang Yuanding heard this, he immediately laughed angrily: "What do you mean that your brain is in the water?" ”

However, he also knew that Zhang Sijiu was teasing himself, and he was not really angry, but just looked at Zhang Sijiu with a sad face: "I'm afraid that something will happen to you." Your family is like this, I'm gone, there is no one to protect you, you must not be so arrogant anymore. ”

I'll break it tomorrow...... I had a fever of 39.5.........
