Zhao Yan asked Cao Tong and Zhilugu to wait for a while, then left the study and came to his bedroom, pulled out a large wooden box from under the bed, opened it, and took out a cardboard box from inside, the express list on it has not been completely torn off, which made Zhao Yan also a little emotional, this carton is the microscope he brought when he crossed, and it was precisely to go to the city to get this microscope that he was struck by lightning on the road, and as a result, he crossed to the Great Song Dynasty at once.

At that moment, Zhao Yan returned to the study with the box of the microscope, and then gently put it on the table and said: "Two, the thing in this box is called a microscope, and it can magnify the image of a thing thousands of times in front of us!" ”

Zhao Yan said, took out the microscope inside under the surprised gazes of Cao Tong and Zhilugu, and then took out the matching two glass pieces from it and put them under the objective lens, and said: "Now let's make a simple real yàn first, that is, let's see what our head looks like." ”

"Head? Isn't the head just a thin hair, and what's so beautiful? Zhilugu asked a little puzzled, he didn't understand much about Zhao Yan's explanation just now, mainly because he couldn't figure out how the microscope could magnify something thousands of times?

Regarding Zhilugu's question, Zhao Yan did not open his mouth to explain, but smiled and said to him: "Straight Divine Doctor, how about borrowing your head?" ”

"I'm not straight!" Zhilugu protested weakly again, but even he knew that it would not have any effect, and I was afraid that the title of "Straight Divine Doctor" would be called by Zhao Yan all the time. But even so, he plucked a white head from his head and handed it to Zhao Yan. He wanted to see what this complex-looking microscope was for.

Zhao Yan took his head and put it on the carrier plate, then covered the cover plate again, and began to adjust the microscope, until he saw a rope-like head through the eyepiece on the guò, then he nodded with satisfaction, and turned to Cao Tong and Zhilugu next to him: "Whoever of you two comes to take a look first, the head under the microscope will definitely scare you!" ”

"I'll come first!" Although Zhilugu was older, he was the most uncontrollable, and he was the first to come to the microscope at that moment. Follow Zhao Yan's example and put his eyes on the eyepiece. This microscope is a binocular microscope, so you don't have to close one eye, and you can see more clearly, and when Zhilugu sees a head like a rope. And there are many burrs on it. At that time, I was also shocked and speechless. It took a long time to reluctantly take his eyes off the microscope.

"Brother Zhilu, what did you see, why were you so surprised?" Cao Tong saw Zhilugu and watched it for a long time. In the end, he stood up with a shocked face, which made him ask too.

"This ...... You might as well see for yourself! Zhilugu didn't know how to explain it, so he smiled wryly and pointed to the microscope and said, if the one he just saw was really his own head, it would be amazing.

Cao Tong also felt very puzzled at this time, and immediately walked over and put his eyes on the eyepiece, but he was also shocked, is this thing full of burrs in front of him really Zhilugu's head?

Zhao Yan saw Cao Yan and Zhilugu were full of shock, and immediately smiled and said: "From my explanation just now, the two of you may not quite understand the role of the microscope, but now you have also seen that this microscope, just like its name, can magnify a tiny thing thousands of times, so that we can easily observe, what you saw just now is only our head, if you want, I can also let you see the most basic part of our body - cells!" ”

"Cells? What is that, and what does it have to do with the virus you just mentioned? For the first time, Cao Yan and Zhilugu felt how ignorant they were, and the knowledge that Zhao Yan said was like a fantasy to them.

"Hehe, cells and viruses don't have much to do with each other, if you have to say anything, that is, they are very small, both of them are medical masters, and they must also know that our body is composed of bones, blood, muscles, internal organs, etc., but in my opinion, although the structure of our body is very complex, there is one of the most basic constituent units, that is, cells, but cells are very small, it is impossible to see with the naked eye, but with this microscope can be seen lightly."

Zhao Yan paused when he said this, and then explained: "Since we know that our body is composed of invisible cells, then around our body, there are also many microorganisms that are invisible to the naked eye, and this kind of microorganism is roughly divided into three types, namely bacteria, fungi and the viruses I just mentioned. Do you two understand? ”

After listening to Zhao Yan's words, Zhilugu and the two looked at each other, although the knowledge that Zhao Yan said was incredible, but the explanation was very clear, and they could understand it, but when they thought that their bodies were actually composed of that kind of small thing called cells, the two of them still couldn't believe it.

If there was no microscope, Zhao Yan would naturally not say this to Cao Yan, after all, this knowledge is too advanced, and they will not believe it, and even think that Zhao Yan is crazy, but seeing is believing, Zhao Yan planned to let them see it with their own eyes, so he ordered the little bean sprouts next to him: "Little bean sprouts, you go to the kitchen and get a piece of mutton!" ”

I wanted to see the cells on the human body, but Zhao Yan was afraid of pain, so he wanted to use mutton instead, it was the same anyway, but at this time, Zhilugu opened his mouth to stop it: "No need, if you want to see it, just look at the human cells, or use mine!" ”

Zhilugu said, took out a knife from his waist, rolled up his sleeves and was about to cut his arm, it is estimated that this knife will get at least two taels of meat, and the frightened Zhao Yan hurriedly stopped: "Straight and slow, just a little skin, don't cut too much!" ”

Hearing Zhao Yan's words, Zhilugu gently slashed his arm with a knife, and actually took off a little skin, Zhao Yan hurriedly put this piece of human skin on the slide, and then asked the little bean sprouts to dissolve her usual rouge in the water, and when the water turned red, a drop of red water was dropped on it, which is mainly because the rouge has red pigment in it, which can dye the cells, which is easier to observe.

After making these preparations, Zhao Yan put the slide under the microscope again, and after adjusting the focus of the light, he could see the cells on the skin one by one, and they were very clear, which made him very satisfied, and asked Zhilugu and Cao Tong to watch it again, but this time after reading it, they were silent, after all, these things that Zhao Yan said today have completely subverted their previous medical knowledge, and they need to digest it for a while.

After a long while, Cao Yan breathed a sigh of relief, and then looked at Zhao Yan solemnly and said: "Son-in-law, I remember that there is a saying in Buddhism, that there are 108,000 living beings in a drop of water. ”

Hearing Cao Yan's words, Zhao Yan smiled and said: "I have also heard what my grandfather said, it is definitely not an exaggeration to store 100,000 living beings in a drop of water, and there may even be more of them, after all, those microorganisms are too small, for example, some viruses are so small that even the microscope in front of us can't see them." ”

Zhao Yan's words are definitely not an exaggeration, the microscope he brought is already very advanced, otherwise it would not be so expensive. The limit of the optical microscope can magnify objects by 1,600 times, and some large viruses can be seen by this microscope, which is beyond the limit of the optical microscope and can only be seen with the help of more advanced electron microscopes.

"I see, I didn't expect Buddhism to be ahead of our Taoists at this point, but I don't know how those monks knew that there were so many microorganisms in a drop of water, could it be that they also have a microscope?" Cao Tong also said to himself when he heard this, the dispute between Taoism and Buddhism has never stopped, and Cao Tong, as a representative figure in Taoism, naturally does not want to see Buddhism overpower them in doctrine.

However, as soon as Cao Tong's words fell, Zhilugu finally woke up from the shock at this time, and glared at Cao Tong at the moment and said: "Now is not the time to pay attention to your Taoism and Buddhism, what the king said today, although it subverts some of our medical theories, but it also opens another door to us, if we concentrate on research, we will definitely be able to make medicine to a higher level, to a height that no one has reached before!" ”

When Zhilugu said at the end, his two eyes burst out with an eager look, he and his father, obsessed with medicine all his life, always want to promote medicine, so as to save more people, but unfortunately his strength is limited, even if he has the name of a miracle doctor, but he can't really promote medicine, at most like his father, he will write books in the future, add a little strength to medicine, but now Zhao Yan said that these new knowledge has made him see hope, if he can study medicine on this basis, It will definitely be able to set a precedent for a generation, and even become a figure like Hua Tuo and Bian Que.

Cao Yan's medical skills are not under Zhilugu, and he naturally thought of the above, but he is not a lonely person like Zhilugu, but one of the leaders of the Daomen, the prosperity of Buddhism in the Great Song Dynasty has overwhelmed the Daomen, and the people in the Daomen have been looking for opportunities to revitalize the Daomen, and he has been suffering from no opportunity before, so he can only practice in seclusion in the deep valley, but today Zhao Yan's words have enlightened him, maybe there is a good opportunity in front of him.
