Daming: I, Yang Xian, really govern Yang!

For the construction of the medical school, Yang Xian only provided a design drawing at the beginning, and then did not participate in the entire process.

Because he has other more important things to do.

Taking advantage of the smallpox incident, Yang Xian struck while the iron was hot and carried out the health and medical reform of the entire Ming Dynasty. Since it was a reform, it was naturally revolutionary.

Yang Xian's purpose is to integrate technology with today's medicine and push Chinese medicine into a new world.

The first thing to do is to allow these doctors from all over the country to open their eyes and embrace science.

This is what Yang Xian is doing these days.

He was making a microscope.

Yang Xian knew in his heart that no matter how much he said, it would be more direct than letting the doctors of the Ming Dynasty see it with their own eyes.

The principle of making a microscope has actually been mastered for a long time. The basic principle is similar to that of a telescope. Its purpose is to magnify objects. However, the two are somewhat inconsistent in their research directions. One is to shorten the distance, and the other is to pursue making the object infinite. get bigger.

To put it figuratively, a microscope is actually a compound telescope.

Yang Xian redeemed the corresponding technology tree from the system, and then studied it. He soon understood that it was almost a natural thing.

I don’t know since when, but for Yang Xian, receiving new technologies and new knowledge became as easy as eating and drinking. No, it’s even simpler. It should be said that it became as easy as breathing. He could learn it once he saw it.

Through this period of hard work, Yang Xian personally built a fixed microscope that can magnify about 800 times.

This kind of microscope can already clearly see bacteria on the human body. It's not that Yang Xian doesn't want to make one with a higher magnification, but it's just that it takes a lot of effort to polish the lenses.

Time flies.

Soon the day came for the official opening of Daming Medical College.

On this day, countless doctors poured into the medical school.

Xiao Jiuxian and Tan Yunxian were also mixed in the crowd.

In ancient times, doctors were generally from medical families, and of course there were also barefoot doctors who became monks on the way.

But no matter what, it is rare for people of noble background to learn this.

Han Yu once said in "Teacher's Theory" that a man of witchcraft, doctor, musician, and various skills is looked down upon by a gentleman.

From this, we can see the social status of ancient doctors. Even Zhang Zhongjing, who was revered as a medical sage, has never been seen in official history.

Although the imperial doctors in the imperial hospital have official status, the head of the hospital is only a fifth-rank official, and ordinary doctors are only seventh- or eighth-rank officials.

But under such circumstances, a distinguished figure came to the medical school ceremony today.

Yang Xian, who was sitting in front of the lecture, recognized at a glance the fifth son of the emperor, Zhu Ju, who was sitting in the crowd.

This is the so-called dragon-born nine sons who each have their own interests. The twelfth prince Zhu Bai likes to make inventions, but the fifth prince Zhu Ji prefers this medical method.

The establishment ceremony of the medical school was grand and grand. Like the soldiers and teachers before him, Yang Xian believed that the social status of doctors also needed to be improved.

The current prince Zhu Biao stood up personally, and all the imperial doctors in the imperial hospital, except those who were on daily rotation in the palace, also studied at the school like these ordinary doctors.

After Zhu Biao first delivered a grand speech on behalf of the imperial court, the stage was handed over to Yang Xian, the only protagonist today.

Yang Xian looked at the packed seats below, doctors from all over the world, and said: "Since you are here today, from now on you will be the first batch of medical students of Daming Medical College. In the next period of time, I will teach you medical knowledge. It must subvert everyone’s previous medical understanding.”

"So everyone is asked to abandon their inherent ideas and embrace the new modern medicine."

"Studying medicine will be very difficult, because doctors are responsible for the lives of patients. Only those who pass the final graduation examination can work in hospitals in various states across the country. If you want to leave, you can leave now, and the court will give you permission to go back. Traveling expenses."

Yang Xian looked at the people below, paused, and then smiled: "Very good, no one chose to give up midway."

"Then it's better to choose the right day than to hit it. Let's start the first lesson of modern medicine today."

"Can anyone tell me where the disease comes from?"

Xiao Jiuxian stood up, first saluted Yang Xian, and then said generously: "All diseases are caused by Qi. Anger causes Qi to rise, happiness causes Qi to slow down, sadness causes Qi to disappear, fear causes Qi to lower, cold causes Qi to shrink, and heat causes Qi to shrink. The Qi will be deflated, the Qi will be disordered if frightened, the Qi will be depleted due to fatigue, and the Qi will be blocked due to thinking."

After hearing what Xiao Jiuxian said, the rest of the people nodded.

What Xiao Jiuxian said comes from the "Huangdi Neijing", which has always been the correct theory in ancient Chinese medicine.

Yang Xian smiled and shook his head.

Seeing Yang Xian's reaction, Tan Yunxian, who was sitting next to Xiao Jiuxian, immediately stood up and said, "Mr. Yang, do you also think that diseases come from the six qi of wind, cold, heat, dampness, dryness, and fire?"

Tan Yunxian's words also aroused the recognition of some people. His conclusion comes from the Southern Song Dynasty's medical work "Three Causes and One Disease Syndrome", which is also very famous in the medical community.

In fact, what Xiao Jiuxian and Tan Yunxian said has included all the current understanding of the causes of diseases by traditional Chinese medicine.

Xiao Jiuxian talks about internal causes, which are the seven emotions of joy, anger, worry, sadness, and fear that cause human body illness.

Tan Yunxian is talking about external causes. The so-called six qi are the weather effects brought about by natural seasonal changes.

In an era without microscopes and other modern instruments, being able to make such a judgment is enough to illustrate the power of our traditional Chinese medicine. At this time, Western medicine was still at the stage of using witchcraft to save people, while Chinese medicine had begun to develop a systematic system.

Seeing Yang Xian, he still shook his head.

Zhu Ju, who was sitting below, asked: "I dare to ask Mr. Yang, so what do you think the disease is caused by?"

As soon as he finished speaking, countless eyes looked at Yang Xian on the podium.

Everyone wants to know how the man who cured smallpox and is now recognized as the first in medicine in the country would answer this question.

Many people have even taken out pencils and blank paper, ready to start taking notes.

Yang Xian looked at everyone with a smile and said, "Broadly speaking, the reason why people get sick is all caused by microorganisms."

"microorganism?"

The doctors below all showed puzzled looks. The question they all thought about in their minds was what are microorganisms?
Zhu Rui directly opened his mouth and asked the questions on everyone's mind.

Yang Xian smiled lightly and said, "Microorganisms are organisms invisible to the naked eye?"

"A creature invisible to the naked eye?" Xiao Jiuxian frowned and said. "Mr. Yang is the legendary Gu insect in southern Xinjiang?"

The so-called Miao poisons in various martial arts novels are actually various pathogenic microorganisms.

Yang Xian thought for a while, then smiled and said: "Miaojiang poison is indeed a kind of microorganism."

"Since it is a creature invisible to the naked eye, how can Mr. Yang confirm this?" Xiao Jiuxian asked, with a serious look on his face.

He studied medicine with his father since he was a child, and what he saw and learned was the most orthodox theoretical knowledge of traditional Chinese medicine. In traditional Chinese medicine, the so-called Miao witchcraft is looked down upon, so it is difficult for Xiao Juxian to accept Yang Xian's teachings. This statement. Not just him, but everyone else too.

Even though Yang Xian had just conquered and cured smallpox, an incurable disease.

"It's invisible to the naked eye, but I have a way to make it visible to you."

Facing the questioning glances below, Yang Xian chuckled.

As he spoke, Yang Xian lifted up the microscope that had been prepared from under the podium.

Xiao Jiuxian and the others quietly looked at the strange brass instrument on the podium that looked like a lampstand, and everyone showed curious eyes.

When Wu Sihai, the head of the Taiyuan Hospital, saw this strange instrument, his eyes immediately glowed with piety, as if what Yang Xian was holding was an extremely sacred treasure.

Obviously, Wu Sihai had seen the power of the microscope before.

At this moment, he has become Yang Xian's first supporter of modern medicine, and his fanaticism is like a loyal believer.

"What is this?"

Tan Yunxian curiously looked at the exquisite instrument on the podium. He saw that it was about a foot high. There was a copper pillar cast on the circular base. On the pillar was a square anvil, and there was a small round mirror under the anvil. . A height-adjustable cylinder hangs on the anvil.

She had never seen such an instrument.

"This is called a microscope." Wu Sihai, who was sitting aside, explained at this time.

"microscope?"

Wu Sihai nodded and said with a smile: "Yes, this was invented by Yang Guogong. The first instrument used to observe microorganisms in the world, the microscope, is the most magical."

When Tan Yunxian and Xiao Jiuxian saw the old man next to them, they recognized the origin of the microscope at a glance, and couldn't help but said, "I dare to ask the old man his name."

"I'm Wu Sihai."

"Wu Sihai?" Xiao Jiuxian was startled, then immediately held the student ceremony and said. "Sir, he is known as the Holy Hand of the Three Mountains, and is now the head of the Taiyuan Hospital, Dr. Wu?"

Wu Sihai waved his hand and said: "It's all a false name. Now, like you, I'm just a student of Yang Guogong."

People around also heard what was going on here.

After knowing the identity of the old man and Wu Sihai's attitude towards Yang Xian, some of his doubts about what Yang Xian just said were dispelled.

The structure of the microscope made by Yang Xian is very different from the optical microscope used by later high school students for biological experiments, except that it does not yet have a rotating diaphragm and objective lens converter. This is mainly because Yang Xian made the entire process by himself. So too lazy to polish the extra lenses.

There is no technical threshold. After I returned to Yangzhou, I just asked the people in the factory to make it.

Standing on the podium, Yang Xian began to introduce: "This thing is called a microscope. Microscopes, microscopy, are specifically used to observe microorganisms."

Yang Xian said: "Do you want to know what smallpox really looks like? Have you seen the color of death?"

In order to save time, Yang Xian prepared a batch of slices in advance, and the complete smallpox virus could be seen on the glass slices.

As soon as Yang Xian finished speaking, hands were raised enthusiastically.

Yang Xian smiled and said: "Students who have already had smallpox or been vaccinated with cowpox must come up. Everyone has a chance."

Yang Xian's first choice was Xiao Jiuxian, who was the first to speak just now.

Under everyone's envious eyes, Xiao Jiuxian walked onto the stage, first gave Yang Xian a student salute, and then stood quietly aside and watched Yang Xian operate.

I saw Yang Xian pick up a thin piece of glass, carefully place it on the stage, then put his eyes on the objective lens, and while adjusting the focus, he said: "I will adjust it for you first, and I will teach you in the next course." How to debug, you can make various slices yourself to look for microorganisms. Of course, if it is pathogenic microorganisms, you must take precautions, otherwise you will be infected. "

"All right."

Yang Xian stepped aside and said, "Now you can see the original appearance of the smallpox."

"Yes." Xiao Jiuxian swallowed and nodded heavily.

He, who had always been unfazed by favors and humiliations, actually seemed a little nervous at this moment.

Finally, under Yang Xian's encouraging eyes, Xiao Jiuxian stood in front of the microscope, and then followed Yang Xian's example, placing one eye on the eyepiece and looking wide-eyed.

In the chaotic liquid, a hint of golden color stood out.

Several golden brick-shaped unknown creatures were squirming in this chaotic liquid.

"This, is this what smallpox really looks like?" Xiao Jiuxian got goosebumps all over his body. He didn't know whether it was excitement or fear.

Yang Xian nodded and said, "Yes, this is the true appearance of the smallpox virus that has killed millions of people from ancient times to the present. It is what it looks like after it has been magnified eight hundred times."

Generally speaking, the microscope Yang Xian currently builds can only see bacteria.

Bacteria are cells. Although they are small, they are complete living organisms. They can be seen with a microscope at about 200 times.

Although the microscope produced by Yang Xian has a magnification of 800 times.

But viruses are different. They are 1 times smaller than bacteria. The virus is made up of many viruses clumped together into a big black ball. When it attacks, it will separate and burrow into the cells. All it takes is one virus to get in.

Normally, viruses cannot be seen with a microscope of this level.

Smallpox virus is a special case. It is the largest of all viruses. It is smaller than a cell but many times larger than other viruses.

But even so, with the magnification of the current optical microscope, it can only be seen, and no more detailed observation can be made.

As Yang Xian said before, you can only see the color of death.

That's the golden touch.

Under Yang Xian's arrangement, all students went on stage one by one to see the smallpox virus.

Some of them even drew the real appearance of the smallpox they saw while watching.

Yang Xian then said: "If you want to truly understand microorganisms, it is actually best to start observing them from water droplets."

"The Buddha said that there are 84,000 insects in a drop of water. You will soon be able to witness this with your own eyes."

As Yang Xian spoke, he replaced the glass piece of the original smallpox virus specimen and replaced it with a water droplet glass piece. After debugging, the medical students could observe it.

Bacteria are more like living things than viruses, and you can even see them moving.

Therefore, for these traditional Chinese medicine practitioners, the impact is even greater. (End of chapter)
