The speaker saw Fusu interested and introduced some more about the old doctor.

The old doctor was also an imperial physician, but he didn't like to mention old things or report his own name. Others followed people he knew to call him Old Man Xin.

Old Man Xin’s ancestors are amazing. He is a famous surgical expert. His single name is Yizi. His highest achievement is that he was once the King of Qin and Qi. Of course, hemorrhoids are just a minor surgery. He has also treated many external trauma and back sores. The treatment feature is that he dares to use a knife to others.

Old Man Xin also inherited the skill of using swords by his ancestors. When he was young, he was full of energy, did many major things, and made many friends. Later, his son died on the battlefield. His wife could not stand the blow and passed away with her son. Then he plunged into the mountains and did not come out.

The imperial physician was very cautious when talking about Old Man Xin and did not dare to say too much, but after thinking about it, he felt that it was not suitable not to mention it, because when it comes to treating external trauma, he thought that Old Man Xin was the best.

Fusu asked the imperial physician's name and was slightly surprised to learn that his name was Xia Wuqi. He had heard of this name. After Jing Ke assassinated his father in his previous life, his father rewarded an imperial physician who was serving him, and his name was Xia Wuqi, saying that Xia Wuqi had made contributions to protecting the emperor.

Unexpectedly, Jing Ke's assassination did not happen, but he met Xia Wuqi here!

Fusu had a good impression of Xia Wuqi, who dared to rescue him at a critical moment, and immediately invited Xia Wuqi to visit the old doctor who lived in seclusion in the mountains and fields.

Xia Wuqi was a little surprised to hear that Fusu was going to visit him in person.

However, even the king has visited the door to recruit talents many times, so it is not uncommon for Fusu to imitate the king.

Xia Wuqi said hesitantly: "That senior is uncertain, and the junior official is afraid that the young master will make a trip in vain."

Fusu said: "If you can find someone, you can't go there a few more trips." He has nothing to do without him. Of course, he can only be sincere when he visits famous doctors in the world.

Fusu and Xia Wuqi left Xianyang together on the second day.

The place where Old Man Xin lived in seclusion was not too far from Xianyang. He rode a horse out of the city for half a day before he arrived at the foot of the mountain.

It is late autumn, and most of the trees are left with bare branches, which looks very lonely.

Fusu has been practicing martial arts since he was a child. He didn't feel tired after riding a horse for half a day. He tied the horse at the post station at the foot of the mountain, ate something with hot water, and then led it into the mountain by Xia Wuqi.

Wang Li followed him all the way. Because Li You was not around, he had to shoulder the responsibility of guarding the leader, and he talked less than usual, and focused on observing whether there was any danger around him.

Fortunately, the mountain is a bit large and quite remote, and the road is easy to walk. Fusu and his group walked along the mountain road to the depths of the forest. After a while, they saw a forest of persimmons with green persimmons. It was late autumn, but these persimmons showed no signs of ripening. All the trees were covered with green and green, and they couldn't eat them even if they looked.

Walking deeper along the persimmon forest, you will see three or two thatched huts hidden in the mountain nest. When you look closer, you can see a curve of stream passing by the house, and flowing into the medicinal fields in front and behind the house along the bamboo tube that draws water, nourishing the herbs in the medicinal fields.

Fusu felt refreshed and came forward and knocked on the door himself.

After a while, a drooping child ran over and opened the wood door, looked at Fusu and his group curiously, and tilted his head and asked, "Who are you?"

Fusu said, "My name is Fusu, I am from Xianyang. Does Mr. Xin live here?"

"We don't have Mr. Xin here." The drooping child shook his head into a rattle, looking serious like "I've never heard of this person."

Fusu looked at Xia Wuqi.

Xia Wuqi asked tentatively: "Is Old Man Xin here?"

"Old man Xin is here, are you going to see Old man Xin? I'll take you to find him." The droughty boy led them in and jumped forward to lead the way.

Fusu: "..."

Xia Wuqi: "..."

Fusu asked the others to wait outside, and she and Xia Wuqi followed the drooping child to one of the huts. After the drooping child brought the person, he heard a cricket chirping in the distance, and immediately ran happily to move the stones and dig the ground to find the crickets.

"What's wrong with you?" An old man in his seventies stood in the hut. He was old and wrinkled, and was counting the herbs he had already dried. Seeing Fusu and Xia Wuqian, his face was not very good, and he obviously did not welcome outsiders.

"My younger brother Xia Wuqi." Xia Wuqi stepped forward to introduce himself, "I have come to ask my senior for advice before, but I don't know if I still remember it. This is our young master Fusu. I heard that my senior is very skilled in medical skills, so I came to visit you."

Old Man Xin's brows moved, vaguely remembering that there was such a person, but he had been away from the world for a long time and could not remember the appearance of Xia Wuqi.

He had heard of Fusu because someone he had saved had sent bamboo, papyrus, straw, and pancreas. He said that it was popular outside, and it was all made by Fusu, the eldest son.

Old man Xin looked at Fusu and found that Fusu deserved to be a person who was called "the fairy child" since childhood. As his childishness gradually faded, his eyebrows and eyes gradually grew, and the "fairy spirit" became more and more obvious.

Fusu doesn't look like he was injured, so why did he travel through mountains and rivers to find him, an unknown old guy?

If it had been decades earlier, Old Man Xin might have been excited because he had the opportunity to climb up to a noble person like Fusu. Now it is different. He has been half-tied and has no thoughts about facts such as fame and fortune. Even if he knows that the half-grown boy in front of him is Fusu, the young man who everyone praises outside, he will not have any fluctuations in his heart.

Old man Xin's expression was calm and asked again: "What's wrong with you?"

Seeing that Old Man Xin was cold and undisgusted, Fusu came forward to explain his purpose and showed the battlefield first aid plan he copied to Old Man Xin.

Because of his family background, Old Man Xin had read a lot of medical books before, so of course he recognized all his words. He sat down and read the plan brought by Fusu, and said, "This is not very good."

Even if there is a doctor on the battlefield, all you can do is to stop the blood, cut the rotten meat in the wound, and then bandage the wound whole. No one else can do anything about it. It depends on whether the wounded soldiers can survive.

Fusu said honestly: "I always feel it's not enough."

He told Old Man Xin about the incident when he saw the wounded soldiers in Wang Jian's mansion that if many injuries were cured in time at the beginning, they should not have to have their arms or legs broken, and some soldiers who died should not have to have to die.

He wanted to know if there is a better treatment for larger wounds?

Old man Xin's hand suddenly shook when he heard this.

He thought of his son.

His son went to the battlefield at a young age and could not even come back. He was buried on the spot by his comrades. He cured people for most of his life, but he could not cure his wife's sadness. Not long after, his wife died shortly after hearing the bad news. He no longer was eager for fame, wealth and wealth, and was fond of everything. He only lived in the mountains and fields to guard his wife's grave and live.

In the blink of an eye, the new grave turned old grave, and his hair turned white. His wife and son had never come to his dream for so many years.

Old Man Xin looked at Fusu in front of him, and suddenly realized that his son always liked to ask him questions like this when he was young. He was very curious about everything and was very serious about everything. When he saw that the small animals in the mountains were injured, he would collect herbs to treat them. Before his son set out to fight, he said that he would definitely save many people this time and live up to the medical skills he had learned.

God is not good at seeing his son, so he is so good that he can't come back alive.

Old man Xin said, "There is a method, but it sounds scary." He turned around and took out a box and opened it in front of Fusu. The box had needles of different sizes and threads of strange colors on the other side.

Fusu sat upright, took out the thread from the box and held it in his hand, and found that the touch was completely different from the ordinary thread.

Fusu couldn't help but ask: "What line is this?"

"This is a thread made of sheep intestines," said Old Man Xin. "This is a method passed down from our ancestors. This thread can be used to suture wounds, just like suturing cloth pieces. After using such thread to suture the wound, the wound will heal faster. However, the process is more painful and you have to use internal medicine to suture it. Otherwise, most people will not be able to withstand the needles and thread them in the flesh."

Old Man Xin added that even if it is sutured, it will not be cured. After suturing, the wound may rot and expand again, which will eventually lead to a high fever that will not subside and will never wake up again.

In short, it is best not to be injured. If you are injured, you can only pray that you can survive.

This treatment method does sound a bit scary and most people dare not think about it.

When Fusu was told by Old Man Xin, he also remembered that he had seen similar treatment methods. However, what he heard at that time was that a mother had difficulty giving birth. A doctor with excellent medical skills went to deliver the mother. The delivery method was to cut a person's belly open and take out the child!

What is even more shocking is that the mother and son were safe when they took the caesarean section!

This shocking practice caused a lot of shock in that small world!

Fusu is not easy to enter the delivery room, so naturally he has not observed the specific process. He met the doctor who delivered the baby and heard the other party talk about the principle of caesarean section. The other party once told him that the skin of a person is exposed to external evils all year round and always plays a barrier. The most important thing is to isolate the external evils. Therefore, not only should the environment be cleaned, but the objects used should also be roasted one by one or thoroughly cleaned with extremely strong wine.

That's all Fusu heard. He was a little thin-skinned at that time and had no nerve to ask in depth about other people's childbirth.

The two things of giving birth to a child and treating trauma are far from the same, and Fusu never remembers this.

After Old Man Xin said this, he linked two things. The wound of taking the child with caesarean section must be quite large. At that time, the doctor should have used the sutures mentioned by Old Man Xin?

Fusu immediately told Old Man Xin about the "skin barrier theory" he had heard, and asked Old Man Xin if he was careful not to let external evil invade, which would be helpful for the healing of the wound.

After hearing this statement, Old Man Xin couldn't help but think seriously.

The concept of external evil is very general. Everything outside the world may be "external evil". It is impossible to isolate all "external evils". However, it is obviously a correct idea to keep the environment clean as much as possible and try to clean the utensils used.

Old man Xin said, "This is the reason."

The two of them discussed back and forth for several rounds, and they improved the stitching method passed down by Old Man Xin's ancestors a lot.

Xia Wuqi was so sensible that he didn't notice that it was getting late. It was not until Wang Li came in to remind him that he might not be able to return to Xianyang today, and Fusu noticed that time passed so quickly.

Fusu said goodbye to Old Man Xin, stayed at the foot of the mountain station with Wang Li and others for a night. On the next day, he entered the mountain early and continued yesterday's discussion with Old Man Xin.

Fusu did not ask Old Man Xin to come out, and Old Man Xin did not ask. After the two of them carefully concluded the implementation plan of the stitching method, it was already noon. Wang Li and the others made lunch on the ground. The old and the young sat on the ground and enjoyed a not particularly rich delicacy.

After eating and drinking, Fusu should go back.

Xia Wuqi was hesitating whether he would help Su invite Old Man Xin to Xianyang, but he saw that Old Man Xin had already asked the child to take out a package.

Old Man Xin said to the drooping boy: "I don't have to come here for now when I go back to your house."

The drooping boy cheered twice and ran away.

"Let's go." Old man Xin ignored Xia Wuqi, who was a little surprised, and said straight to Fusu.

Fusu laughed and followed Old Man Xin to the persimmon forest.

The author has something to say:

Fu Xiaosu: Go out to pick up talents!
