Liu Yong and Dong Yun waited for a while, but there was no movement over there. Pen, fun, pavilion www. biquge。 info: "Will we be copied from both sides?" Liu Yong said with some concern.

Dong Yun was shocked when she heard this, and said miserably: "Big brother is rightly worried, I'm afraid it's too late." ”

When the two looked back, they were surrounded by people.

Liu Yong and Dong Yun didn't expect to finally get out of danger but become prisoners, so they couldn't help but look at each other and smile bitterly, sighing that creation makes people. "Stay in the green mountains, don't be afraid of no firewood", Liu Yong didn't want to make a senseless resistance, and pulled Dong Yun to the open place together.

"Yun'er, don't be impulsive yet, let's see the situation first." Liu Yong whispered in Dong Yun's ear, "Of course, if the bandits have misdeeds against you, I will die here with you." Dong Yun nodded, but her heart was sad and sweet.

"Come out all the heroes of the woods. In Xia Liu Yong, I will bear everything alone, I just ask you to let this girl go, and I am grateful. ”

Dong Yun was even more moved, her eyes were red, tears flowed down, and she just wanted to speak, but she heard someone say in surprise, "Sure enough, it's the head of the regiment." ”

Liu Yong was overjoyed and surprised, and more than a dozen soldiers came out of the forest, all of whom were his subordinates. When Liu Yong asked, he found out that Dong Xi saw that the two had not returned for a long time, and he thought that something must have happened, so he personally led the team to look for it. Dong Xi searched along the medicine collection route that Dong Yun had told him earlier, first found the mounts of the two, and then followed the mountain road to find the medicine collection place of the two. Here they found two ropes tied to the trunk of a tree that had been bitten by animals, and there were still stones and traces of rope wear on the edge of the cliff, so it was known that the two must have encountered a beast. Dong Xi was anxious, worried that the two of them would fall into the deep valley, so he immediately divided the soldiers into several groups, and after descending the mountain, half to the left and half to the right, they all searched for the deep valley.

Therefore, the place was not far from the bandits' nest in Qinglong Mountain, and everyone did not dare to raise fire, nor did they dare to shout, but they had to search carefully, so they did not find this place until dawn. Liu Yong saw that all the soldiers were dusty and tired, but when he saw that he was overjoyed, he couldn't help but feel ashamed, and thanked him again and again. After a while, Dong Xi also rushed over quickly after receiving the report.

Liu Yong was overjoyed when he saw Dong Xi's face, but his eyes were bloodshot, he looked extremely tired, and he was even more ashamed, and apologized: "Brother Dong, brothers. Liu Yong's reckless behavior makes you tired and frightened, but I can't help it. ”

Dong Xi and the army returned the salute again and again, saying that the regiment commander was thinking about his brother's health and well-being, and there was no need to do so. Liu Yong knew that this act of collecting medicine was too rash, and if he really made a mistake, this army, which was finally getting together and gradually getting on the right track, would probably fall apart again, or act like nothing wrong, and it would really be a waste of success. Liu Yong immediately said that he would review it in front of all officers and men at the meeting and never commit another crime.

Dong Xi knew that Liu Yong's personality was not persuasive, and when asked about the experience, Liu Yong described the distress in detail, and everyone said that "Jiren has his own natural appearance". Therefore, the land is still within the sphere of influence of the bandits' nest in Qinglong Mountain, and everyone does not dare to celebrate, but they are still hiding and quietly returning to Fuyi.

Dong Xianzi and the soldiers returned to the barracks, while Liu Yong and Dong Yun went to the post house to see Hua Tuo. After Hua Tuo got Sanqi, he couldn't wait to apply it to the injured soldiers, and its effect of stopping bleeding and reducing swelling was indeed far from being comparable to ordinary drugs, Hua Tuo's eyes lit up, and he said happily: "Childe's insight is really unpredictable, and the old man knows how to stop bleeding." In this way, surgery reduces the risk of bleeding and can save more pain. As he spoke, he bowed deeply to Liu Yong, "Thank you, son." ”

Liu Yong was startled, and quickly helped Hua Tuo up, and said, "Mr. Hua praised it falsely. Mr. Hua worries about the world and always remembers the pain of the people, which is the style of the world's famous doctors, and Liu Yong deeply admires it. ”

Hua Tuo worried: "The old man thinks that this medicine is extremely useful, and if it is dug up like this, I am afraid it will not take long to dry up." ”

Liu Yong nodded and said, "But that's the case." But there is no need to worry too much, sir. Hua Tuo was overjoyed when he heard this, "What is the good way for the child." ”

Liu Yong smiled and said: "There are too few wild ones, so let's cultivate them artificially." Although the medicinal effect is worse than that of the wild one, it is inexhaustible. ”

Hua Tuo said happily: "Childe actually knows the art of cultivation. ”

Liu Yong said with a smile: "I understand a little." These precious medicinal materials, Panax notoginseng, Dendrobium, ginseng, gastrodia, etc., can all be planted artificially. Of course, the conditions required for each herb are different......"

The two happily looked forward to it, and Liu Yong asked again: "Mr. Hua, Liu Yong has something to ask." ”

Hua Tuo was in a good mood, and said with a smile when he heard this: "Son, please speak." ”

Liu Yong said: "I remember that there is such a sentence in a medical book, 'Therefore, the disease is not cured, the disease is not cured', is that what it says? ”

Hua Tuo said with a smile: "This sentence comes from the "Yellow Emperor's Neijing" "Su Wen? The original words of the Four Tempering Spirits are: "Therefore, the saint does not cure the disease, and the disease is not cured, and the disorder is not cured, and this is also said." The husband's illness has become a medicine, and the chaos has become a cure later, such as thirst and piercing the well, fighting and casting a cone, and it is not too late'. ”

Liu Yong patted his head and said with an embarrassed smile: "I can't remember the original words below, but I know the meaning inside." If the disease has already been formed, it will be cured, and the **** will be pacified only after it has occurred, which is like digging a well when the population is thirsty, and the enemy has to fight in front of him to cast weapons, isn't it too late? This means that we must grasp the timing of our treatment, and the sooner the better. ”

Hua Tuo smiled: "Exactly, it is easy to get sick and difficult to cure." Therefore, there is a folk proverb, 'Sickness comes like a mountain, and illness goes like a thread'. ”

Liu Yong said to Dong Yun, who was listening silently on the side: "Yun'er, you have been studying with Mr. Hua for two months, you tell the eldest brother what the cause is." ”

Dong Yun let out an "ah", very surprised, her face flushed, and she stammered: "Does the eldest brother want me to answer?" I've only been learning for a long time. As he spoke, he looked at Hua Tuo as if asking for help.

Liu Yong smiled lightly and said, "Simply put." Hua Tuo also encouraged on the side: "Yun'er, don't panic, you just follow the answer that the master usually teaches you." ”

Dong Yun agreed, and after a moment of silence, he replied: "The cause is roughly divided into two types, external sensation and internal injury. The external senses are divided into wind, cold, heat, dampness, dryness, and fire, which are called the 'six prostitutions'; and the internal injuries are the seven feelings of intemperance, which are subdivided into joy and sadness, anger and liver, fear and kidneys, sorrow and spleen, and sorrow and lungs............"

Liu Yong nodded, and asked Dong Yun again, "What about pathology?" ”

Dong Yun thought about it again, and fixed his mind: "Generally speaking, pathologies are nothing more than the growth and decline of evil, the imbalance of yin and yang, and the abnormal rise and fall. As he spoke, he looked at Hua Tuo again, and when he saw Hua Tuo nodding, his heart, which was beating wildly, calmed down a little.

Hua Tuo was puzzled: "Childe must have a deep meaning when he asks this, right?" ”

Liu Yong bowed his head and said, "Hmm." Just now, Mr. Hua and Yun'er talked about the theoretical basis of our Chinese medicine. The five elements of yin and yang, the blood of the guard, the meridians of the viscera, the diagnosis method pays attention to looking, smelling, asking, and cutting, and the dialectic pays attention to the eight outlines of yin and yang. This is the basic theory of Chinese medicine, which emphasizes the unity of mind and spirit, and the unity of man and nature. 'From yin and yang to life, reverse is death', this is a holistic and macroscopic concept. ”

"Big brother!" Dong Yun was a little puzzled and asked, "Do you mean that in addition to traditional Chinese medicine, there are also 'foreign doctors'?" ”

"Yun'er is smart." Liu Yong grinned and praised, "But the name is not 'foreign medicine', but 'Western medicine'." ”

"And Western medicine?" Hua Tuo said in surprise, "Is there any difference?" ”

Liu Yong nodded and said: "The biggest difference between Western medicine is that it is based on human anatomy, histology, embryology and pathology, and pays attention to local and microscopic. Seeing that Hua and Dong were full of doubts, Liu Yong said again: "Generally speaking." To study Western medicine, it is necessary to dissect the human body and observe the position, size, texture, color, and so on of various organs. ”

Dong Yun was dizzy, "Big brother, it's so disgusting." ”

"Disgusting is secondary. In our country, we talk about 'the body is skinned, and the parents who receive it dare not destroy it'. How, then, can we understand what our bodies are like? Take Mr. Hua as an example, if he hadn't dissected many corpses, he knew what the human body was like and what it was like when he was sick, how could he dare to have surgery? ”

Dong Yun was stunned for a moment and muttered, "Could it be that Mr. Hua also dissected the corpse?" ”

Hua Tuo looked at Liu Yong in a daze and sighed, "That's true." If it weren't for the fact that there were so many uncollected corpses during the war, how could the old man have the opportunity to understand the structure of the human body. If the old man didn't dissect these corpses, how could he know how wrong the description of the heart and intestines in ancient medical books was. ”

Liu Yong Zhengse said: "There is one more thing to say next, which is also extremely important at present. ”

"Childe, please speak." Hua Tuo said solemnly.

"For internal injuries, both Chinese and Western medicine are similar, the difference is the external sense. Traditional Chinese medicine believes that the disease is caused by the invasion of the six prostitutes, while Western medicine believes that the external sensation is caused by the human body being infected with a small thing called a microorganism. ”

"Infection? Microbe? Hua Tuo and Dong Yun were even more dumbfounded.

This problem has to be explained well, Liu Yong thought for a while, and said, "We have that parasite in our bodies." It's the worm that lives on us. Liu Yong sweated on the top of his head, and gave an example, "Some live in the body, such as roundworms in the intestines, and some live on the surface of the body, such as bed bugs, lice, etc., these things will affect our lives at least, and at worst make us fall in physical condition or even get sick or die." Am I right? ”

Hua Tuo and Dong Yun glanced at each other, nodded their heads, and only listened to Liu Yong say again: "Similarly, although these roundworms and lice are small, their structure is similar to ours, and they will also parasitize smaller insects on their bodies, which will also make them sick." In the same way, these smaller bugs will have smaller bugs growing inside them. Western medicine believes that all our external diseases are caused by these tiny insects, which are called microorganisms, and they invade our bodies to cause diseases called infections. ”

"It's just speculation, is there really such a little bug?" Dong Yun was still a little puzzled.

Liu Yong said in a firm tone: "Yes." It's just that they're so small that our eyes can't see. ”

"How do you know that there is one if you can't see with your eyes? Isn't it a contradiction for the eldest brother to speak? ”

Liu Yong smiled and said, "I haven't finished yet." Although our eyes can't see, we can use a special method, such as magnifying these small things, and we can see them. ”

"Zoom in? What do you mean? Dong Yun was even more puzzled.

Liu Yong thought about it, picked a leaf from the flower pot, rolled it into a small cylinder, tied it tightly with a needle, and then dipped it in a drop of water at the front end of the cylinder, and then handed it to Dong Yun and said, "Yun'er, you use the cylinder to look at the words on the paper." ”

Dong Yun took it suspiciously, looked at the word with the cylinder, and immediately said in amazement: "The word has really become bigger." Mr. Hua, you can also take a look. Hua Tuo also looked at it, and sure enough, the characters became bigger.

Liu Yong continued: "This is just the most ordinary and simple magnification, if set up properly, it can magnify the original thing dozens or thousands of times. We can see a lot of things that we don't normally see. Hua Tuo and Dong Yun glanced at each other, only thinking that it was incredible, but it was reasonable, it was really like a dream.

"I'm going to make one of these devices in the future, so that the two of you can see these little bugs with your own eyes." Liu Yong is still very confident in making a simple microscope.

"I don't want it, it's disgusting to think about." Dong Yun couldn't help but feel creepy when she thought of those wriggling insects.

"I believe that what is the name of the one that Gongzi said...... That's right, microbial stuff. Childe has said so much, what do you want to explain? Ah, the old man knows. ”
