"A microscope is an optical instrument composed of a lens or a combination of several lenses, which is a sign that mankind has entered the atomic age." -- From "The Age of the Biological Atom".

When Liu Qi and Zhang Er cautiously walked up with a microscope, Sun Simiao and Yuan Tiangang both showed puzzled expressions.

Xu Yang walked up, took out an iron cylinder object from his arms, and shook it in his hand, and Sun Yuan and the others were attracted to him again.

"If you want to talk about this microscope, you have to talk about the principle of this microscope first, otherwise the two of you may be a little surprised later." Xu Yang fiddled with the iron cylinder in his hand and said.

"If you want to talk about the origin of this microscope, it is that my eighth generation ancestor of Guigu accidentally discovered that two pieces of glass with different thicknesses can be superimposed together to produce an unknown effect, so he studied hard, and finally discovered that two convex lenses can be stacked together to make a telescope, and two concave lenses can be stacked together to make a microscope." Xu Yang smacked his lips in satisfaction and continued: "In my hand is a telescope with two convex lenses stacked on top of each other, and in the hands of the servants is a microscope. ”

Yuan Tiangang and Sun Simiao listened to the clouds, and they only knew that it seemed to be something magical.

Xu Yang handed the thin iron cylinder in his hand to Yuan Tiangang and said, "You two can use this telescope to take a look first." ”

Yuan Tiangang took the thin iron cylinder handed by Xu Yang, and according to Xu Yang's instructions, he picked up the lens tube, looked out the window at one end, and looked at the other end.

Then there was a trembling voice in disbelief: "A thousand clairvoyants?!" ”

Xu Yang was picking up a cup and drinking tea, and when he heard this, he almost didn't squirt it out, Lao Yuan is too imaginative, and he can always explain something inexplicably.

When Sun Simiao heard Lao Yuan say this, his curiosity rose, and he wanted to come over the telescope and look out of the window, and he let out a surprised sound just now.

I saw that the trees on the mountains in the distance seemed to be right in front of me, and the snow in the shadows had not yet melted, and the scenery was vivid, as if I really had the divine power of clairvoyance.

After looking at it for a while, Sun Simiao put down the telescope and praised: "It's really a magical thing, it can actually move the vista forward, and it deserves to be called a telescope." ”

Xu Yang nodded with satisfaction, people are much calmer when they get older.

"The two of you just looked at the telescope, and now this microscope is not difficult to understand." Xu Yang boasted: "The principle of the microscope is not much different from the telescope, but a telescope, a microscopic one, Sun Daochang, please move to this table, don't block the vision, yes, come here, come here, come and see the microscopic world." ”

Sun Simiao stood in front of the microscope, Xu Yang helped him adjust the quasi-focus spiral, the technology of the Tang Dynasty was still too backward, at most more than 300 times magnification, even the process drawings could not continue to magnify, the level of technology was there, it was an insurmountable gap for this kind of subtle precision instrument.

Xu Yang carefully put a specimen of a fly on the slide, adjusted the refractor, first took a look at it himself, and then asked Sun Simiao to stand up and look at it.

As a Tang Dynasty 1,300 years ago, Sun Simiao also has his own historical limitations, he is also the first time to contact this kind of microscopic medicine theory, originally he came to Xujiazhuang with a very skeptical attitude, he didn't know, Xu Yang sent him the book "Modern Medicine" is an abridged version, just a rough introduction to the medical outline, did not elaborate, which also made Sun Simiao's heart itch.

Now that he can finally experience it for himself, Sun Simiao stood in front of the microscope, his body trembled a little because of excitement, he poked his eyes out, and saw a huge fly head in front of him, and almost exclaimed.

Xu Yang smiled with satisfaction on the side: "Sun Daochang, now the microscope is magnified by a hundred times, if you want to see bacteria, you need to adjust it to three hundred times, and this fly is not suitable for observing bacteria, I have a petri dish of bacteria collected by people occasionally feeling cold and sneezing, where can you see these bacteria." ”

After visiting the microscope, Sun Simiao was still a little unsatisfied, today's trip gave him too much feeling, he felt that if he followed this idea, the world's medicine could be from the microscopic to the upper level, and those plagues that were not well cured could also be found to be cured, he wanted Xu Yang's microscope very much, but he was too embarrassed to speak.

How could Xu Yang not see the desire in Sun Simiao's eyes, his heart was very excited, he had fooled Li Gang to open a academy and tied Mr. Li Gang to his chariot, but now it is Sun Simiao's turn again, you can't run away from the hospital director.

Rubbing his hands, Xu Yang showed his usual harmless smile and said to Sun Simiao: "Daoist Sun, do you think this is the end?" My ghost valley has been inherited overseas for more than a thousand years, and the achievements of medicine are unimaginable, I don't know if you still want to see it? ”

Sun Simiao didn't think about it, and immediately said: "Xiao Lao'er has been a doctor all his life, just like reaching the peak of his medical career, helping the world and saving people, and there are no injuries or illnesses under his hands. ”

"Hey, hey." Xu Yang smiled very happily, "Where can you use Sun Daochang's liver and gallbladder diagram, as long as you serve as the lifelong honorary dean of the medical school, and you have nothing to teach two classes to the students, you can visit all the Guigu medicine." ”

Sun Simiao was immediately moved, this Guigu disciple is also a person who has the world in mind, and he has no view of the door, so he will teach him all the knowledge, he is really a compassionate person, thinking of this, Sun Simiao made a big salute to Xu Yang and said: "Guigu is so beautiful, the little old man has nothing to repay, and he will carefully teach his disciples medicine in the future." ”

"Hahaha." Xu Yang laughed three times, things went very smoothly, and said loudly: "Zhang Er, lead the way ahead, I, and Sun Daochang and the two disciples of Daochang will go to the medical practice room, and Zhang Er will take care of Yuan Tianshi in front of the hall." ”

"No." The two servants received the order and began to work.

"Daoist Sun, these two disciples of yours are also disciples in the room?" The distance from the front hall to the medical room was a little far, so Xu Yang chatted with Sun Simiao.

"These two are Xiao Lao'er's beloved disciples, I forgot to introduce them to Guiguzi, this is called Dao Nie, this name is Daozhuang, it is a Taoist priest of the Holy Palace, and later worshiped under my door and learned to help the world and save people."

The two beautiful young men bowed down in unison and said, "I've seen Guiguzi." ”

"No need to be polite, what a good boy, he looks sixteen or seventeen years old, and when you get to the real yàn room, my uncle will give you something interesting." Xu Yang is very old-fashioned, he forgot that he was only a twenty-one-year-old hairy young man.

When they arrived at the medical room, this is a novel flat room, which is very common in later generations, but no one has seen it in Datang, and the group is very curious to follow Xu Yang into the house.

Pushing open the door of the room, I saw a few people standing inside, sitting in a hurry, I saw that they were dressed in white, wearing gloves, there were many instruments on the table, and the rest were all organs.

Xu Yang was nothing, and introduced Sun Simiao very enthusiastically: "These are all the works of the Yamen, and now I come to the real yàn room to study human medicine." ”

Sun Simiao's face was a little bad, and he said softly: "You disemboweled, disemboweled, and disemboweled? ”

As soon as Xu Yang heard it, he knew that the famous Sun Simiao was also very taboo about this, the custom of not moving the corpse after the death of the Tang people was a social environment, and he fortunately didn't touch it, so he didn't touch it, and Sun Simiao would leave, after all, in the version of later generations, the social morality of the medicine king was very high.

Xu Yang said softly: "Don't dare, these organs are all pigs and monkeys, and the Taoist can take a look at them for himself." ”

Sun Simiao looked around and found that it was really just pig and monkey internal organs, and his face eased.

Xu Yang picked up a bottle of medical alcohol on the table, took out a thick book from under the table a little mysteriously and said, "Daochang Sun, do you know the real modern medicine?" ”RS
