Speaking of Fangjia Village, Fang Jing was making breakfast at this time, and several little babies in the family were also busy with other things, after Xiao Linghua was fed, she was held in Xiaocao's arms and amused.

"Brother Jing, look at Xiao Linghua, I've been staring at you." Xiaocao was teasing and playing with Xiao Linghua in her arms, but the two little black eyes of Xiao Linghua in her arms kept staring at Fang Jing.

"That's right, Xiao Linghua and I are the closest, and she was brought back by me, so naturally she has been watching me." Fang Jing looked stinky and proud.

"Brother, when Xiao Linghua grows up in the future, she will definitely be a follower." Fang Yuan was burning a fire in front of the stove, feeling a little uncomfortable about Xiao Linghua being loved by Fang Jing, maybe Xiao Linghua would occupy a part of her brother's love when she came to the house.

"Xiao Linghua will grow up in the future, but she won't learn from you to be a fart, Xiao Linghua will definitely be very sensible in the future, just like Xiaocao." Fang Jing was stir-frying vegetables in her hands, and she didn't forget to look back at Xiao Linghua, boasting about the grass in her mouth, it could be regarded as a blow to Fang Yuan, a little girl.

"Hmph." Fang Yuan could only hum a sentence in his mouth when Fang Jing said this, but he couldn't refute anything, after all, Fang Jing would really beat her.

Before breakfast, Sun Simiao and the three of them also came over, and they were quite punctual every day, and they basically figured out when Fang Jing's family would cook and when they could eat, and in the past two days, Sun Simiao and the others were all in the townhouse sorting out the records of the past few days, and they didn't have time to come over to talk to Fang Jing.

"Mr. Sun, don't go back first today, I'll give you that microscope in a while, and teach you how to use it by the way." After eating breakfast and resting for a quarter of an hour, Fang Jing called out to Sun Simiao, who was about to leave.

"Fang Jing, what mirror are you talking about? Quick, quick, let me see. After Sun Simiao heard Fang Jing's words, his heart began to feel a little anxious.

"Mr. Sun, don't be in such a hurry, I'll put Xiao Linghua to sleep first and then get it for you." Fang Jing was still holding Xiao Linghua in her arms, and as Xiao Linghua got bigger and bigger, the time to sleep naturally began to gradually decrease, and it may be even more so in the future.

"Fang Jing, I'm too anxious, then you hurry up and coax her to sleep." Sun Simiao looked at Xiao Linghua in Fang Jing's arms, although he was anxious, but at the moment, he could only do this, but at this moment, he began to dislike the little baby in his eyes, who asked Xiao Linghua to stop him from seeing the microscope immediately.

Fang Jing hugged Xiao Linghua, muttering something in her mouth, in Sun Simiao, she felt that time passed so slowly, and she was a little restless when she sat in the chair.

Two quarters of an hour later, Fang Jing finally put the sleeping Xiao Linghua on the bed, and after explaining a few words to the few little babies at home, she took Sun Simiao and them to her own house.

"Mr. Sun, you see, this is this microscope, basically made of iron and steel, some other things belong to crystal pieces, there is only such a one, Mr. Sun will use it in the future, you have to be careful, as long as these crystal pieces are broken, there is no material to make, and it is difficult to find such a bright crystal." Fang Jing took out the microscope from the back room, put it on a small table, and said to Sun Simiao, of course, those glass pieces and magnification lenses can only be said to use crystal pieces to deceive Sun Simiao, after all, this thing is not easy to say.

"Fang Jing, don't worry, what kind of mirror is this, I will protect it well, but how can I use this?" Sun Simiao looked at the microscope on the table, a little unclear, at least for now, in his eyes, it was just a tool made of steel, although he was curious, but he didn't feel that he was very curious.

"Come, I'll teach Mr. Sun to use this microscope, here is the stage, two crystal pieces, I sandwiched my hair between them and put it on the stage, this is a reflector, adjust the angle to shine through holes on this stage, and directly target the things that need to be observed......" Fang Jing plucked a hair from her head and taught Sun Simiao and the three of them how to use this microscope step by step.

As for where the light source of the microscope comes from, it can only use sunlight, Fang Jing doesn't dare to ask the dumb fairy for any battery bulb microscope, there is no place to replace it if it is broken, and even if this simple old-fashioned microscope is broken, at most it is only a broken lens.

"Mr. Sun, when you look at the stage from this eyepiece, this hair is magnified hundreds of times." After Fang Jing adjusted the distance, he said to Sun Simiao, and then Sun Simiao came over to take a look.

"This ......, this is hair? How can it be? Why is it so coarse? Sun Simiao just moved his eyes to the eyepiece, looked inside, and found that the hair looked like after being magnified hundreds of times.

"Mr. Sun, anything can be viewed on this crystal piece, but when viewing, it is best to hold it down, and if you can, drop a drop of salt water on it, so that it is easier to distinguish." Fang Jing opened his mouth and said to Sun Simiao and the others.

"Fang Jing, can you use this microscope to see the bacteria you talked about a few days ago?" Sun Simiao raised his head and stared at Fang Jing and asked.

"Mr. Sun, don't worry, as long as it is the bacteria carried by the patient, you can see it, but if you want to be very clear, it will be a little difficult, but you can still see it." Fang Jing couldn't guarantee that this old-fashioned microscope would be able to see most of the bacteria, but she could still see some of the larger ones.

"Cheng Fei, you go get a leaf." Sun Simiao shouted to one of his retinues, presumably to get some herb leaves to see how it was.

After hearing this, the entourage named Cheng Fei went out directly to pick the leaves of an orange tree, and after Sun Simiao took the leaves, put them on the tablet, and began to operate according to the method taught by Fang Jing.

"This ......" has been magnified hundreds of times on the surface of the blade, so that after Sun Simiao saw it, he couldn't express anything in words.

"Teacher, how about we?" Sun Simiao's two entourages said to Sun Simiao, wondering what was strange about this microscope.

"Okay, Cheng Fei, Shocking Rain, you can take a look." Sun Simiao hurriedly gave up his position so that his two entourages could easily watch.

"This ...... This...... This....... The two attendants then took turns to look at each other, only to realize that their teacher's expression was not exaggerated at all, but now when they watched, they realized that the surface of the orange leaves they had picked had been magnified countless times.

"Fang Jing, is this microscope easy to make? How much does it cost? Sun Simiao began to think about the production and price of the microscope, perhaps in his heart, this kind of thing should not have appeared in the world, if it did, it would be a subversion of the entire medical community.

"Mr. Sun, this microscope is not so easy to make, even if there is a good crystal piece, it is difficult to make the lens in this eyepiece, the cost, it can only be said to be expensive, and it also requires chance, without the best crystal piece, it cannot be made." Fang Jing couldn't tell Sun Simiao that this microscope was extremely simple to make, even if there was a crystal piece, it was estimated that it would be difficult to make it, at least in terms of accuracy, Fang Jing could definitely not make it.

As far as the current length measurement is concerned, Fang Jingxin clearly knows that there is definitely no more accurate measurement tool, even if there are some, it is estimated that it can only reach the millimeter level, but the eyepiece of this microscope has to reach two levels below the millimeter level, which is not something that can be done simply by talking about it.

"Alas, it seems that my medical field is not blessed, if this microscope can be made in large quantities, I think my medical field will definitely be able to develop greatly." Sun Simiao sighed heavily, the vision in his heart could not be realized, let alone promote the great change of the entire medical field.

"Mr. Sun, these are just foreign things, medical things, I don't know much, but I think that as long as you are willing to teach students, even if you learn some simple medical knowledge first, and then follow you to the field to treat patients, I want to come to this medical skill can also be popularized." Fang Jing suddenly thought that if Sun Simiao was fooled into Mr.'s team, he would definitely be able to teach a lot of students, even if his medical skills could not reach Sun Simiao's level, at least he could treat the majority of patients.

"Fang Jing, your idea is good, but I don't have the patience to teach any students, not to mention that even if I can teach students, the medical skills are also high, so I am afraid that I will miss people's lives." Sun Simiao hurriedly stopped Fang Jing's idea or suggestion.

"Mr. Sun, don't say this in advance, wait for you to think about it later, you should familiarize yourself with this microscope first, after all, this microscope is what you will use in the future." Fang Jing hurriedly stopped this topic, this matter is not in a hurry for the time being, and when he has time to have a good chat with Sun Simiao, I believe that Sun Simiao will change, even if there is no change, Fang Jing can also invite some doctors to come over and be a gentleman.

"Teacher, how can this microscope magnify things so big? The veins on this leaf are so clear that it is difficult for our eyes to see clearly. Cheng Fei kept staring at the eyepiece, looking at the orange leaves on the stage, perhaps in his eyes, it was another world.

"How about you zoom in to four hundred times?" Fang Jing saw that the objective lens was only twisted at a tenfold position, and the leaves were only magnified by a hundred times, so naturally he could only see the veins of some leaves, because the objective lens of the microscope only had three magnifications, which were rotatable, one tenfold, one twenty times, and one forty times, and the eyepiece was fixed ten times, so the multiplication was a hundred times, two hundred times, and four hundred times.

"This ...... This....... When Cheng Fei adjusted the objective lens to forty times, and then adjusted the sharpness, what was observed was basically the cellular structure of the leaves, which naturally shocked the entourage named Cheng Fei speechlessly.

"Cheng Fei, I'll take a look." Sun Simiao saw that his entourage was in such a frightened state, and hurriedly called Cheng Fei away, and he opened his eyes to look at the leaves in the eyepiece.

Sun Simiao kept staring, and he didn't speak, let alone speak at this time, because the leaves in the eyepiece had already shocked him again, just a hundred times just now, which made him indescribable in his heart, let alone four hundred times at this time.

"Mr. Sun, you can watch the bacteria and tiny creatures I mentioned two days ago by dropping a drop of water from the pool, so that you can know why our village basically drinks boiled water or cold boiled water." Fang Jing stood on the side and suddenly interjected.

In recent years, every household in Fangjia Village has basically drunk boiled water or cool boiled, which is also a matter after Fang Jing discussed with the village in order to prevent the villagers from getting sick.

"Cheng Fei, you go get some water." After Sun Simiao heard this, he urged Cheng Fei to get some water, wondering why Fang Jing's family had always drunk hot or cold boiled water, although he was also a person who drank boiled water, and he knew in his heart that there must be something wrong with the water he usually drinks, but he still hoped to confirm something through this microscope.

When Cheng Fei got some water, he observed again, and this time Sun Simiao let go of the doubts in his heart, because after he observed the microorganisms in the water, he was convinced that what was recorded in his notes was correct, and what he wanted in his heart was to verify more things to support his medical notes, and to teach more people to drink boiled water through his own medical books.
