doomsday survival

Chapter 227 Difficulties
Bacillary dysentery is a common infectious disease in summer and autumn. Because there are effective antibacterial drugs, it was not a fatal disease in the old days, but the patient suffered a little.

But now is the end of the world, and all antibacterial drugs have failed. What's more, since the advent of vaccines for all diseases, the production of this drug has become less and less, and production has basically been discontinued.

Fortunately, He and his son had previously received the book of traditional Chinese medicine presented by Shi Jian, which also contained some classic prescriptions for treating dysentery.Once they were diagnosed with dysentery, they immediately took the medicine according to the prescription and treated the symptoms accordingly. At the same time, they isolated the patient to a certain extent according to Shi Jian's instructions.

In fact, there are still a lot of troubles.

First of all, there is the problem of medicinal materials. Many medicinal materials in the recipes are not found in Changbai Mountain area.

Then there is the isolation of patients, which many people do not understand.In their view, the patient needs care at this time. If they are isolated, how can they take care of the patient?
Fortunately, Feng Kuang stepped forward at this time, and as the oldest person in the tribe, he did a lot of ideological work for the patient and his family, and even used Shi Jian's most hated method - pretending to be a ghost, talking about the plague god Such messy celebrations allowed the quarantine operation to proceed smoothly.

Fortunately, the news was controlled in advance, and it was not spread outside. Otherwise, if those people in the valley found out, who knows what troubles would happen.

After the epidemic passed, He Chong said with emotion: "If there is no Principal Shi, we will be in danger this time."

"Well, I have to thank Principal Shi very much. If it weren't for these few medical books you gave us, then we would be helpless." He Feng also said politely.

"It has nothing to do with me. I didn't go to see a doctor. It's all thanks to you." Shi Jian smiled humbly.

"That can't be said like that. If you didn't propose to isolate patients, maybe all the people would be infected." He Feng said to Shi Jian.

"Don't mention isolation soon," Shi Jian said angrily, "I tried my best to persuade you, but as soon as Lao Feng knew what kind of gods and ghosts, these people still believed them. It's so speechless."

Speaking of this, Wang Lie remembered the bet from the beginning, and said to Shi Jian: "I said Principal Shi, can we still make that bet?"

Seeing that Wang Lie hadn't forgotten about this incident, Shi Jian smiled and said, "Of course I did. Give me a few days, it's okay, right?"

Wang Lie nodded and said, "Of course, I don't know how long Principal Shi will take?"

Shi Jian calculated silently in his heart, and felt that three days should be about the same, so he said to Wang Lie: "Three days, it should be able to be made."

"That's good. I believe that with President Shi's ability, he can definitely make a microscope by himself, right?" Wang Lie said with a smile.

When Shi Jian heard this, he tilted his head and looked at Wang Lie. He didn't expect that Wang Lie, who was simple and honest in appearance, would play with himself in such a narrow-minded way, and even specially emphasized the word "alone", which made him a little dumbfounded .

"Okay, it's really not a difficult task. I can really handle it alone. Then we will see in three days." Shi Jian said confidently.

Seeing Shi Jian's self-confidence, Wang Lie couldn't help being startled, and thought to himself, "Isn't this going to bother him? Maybe I should think of something else."

Shi Jian didn't know what Wang Lie was thinking, so he went straight to make preparations.

The principle of the microscope is actually very simple, as long as two convex lenses are used, plus a frame.

Shi Jian also does not intend to make a microscope that can magnify thousands of times, as long as it can reach the level of Leeuwenhoek, it is enough to see the microorganisms in the water.

After returning home, Shi Jian tidied up briefly, and then went to the lime kiln to see if there was a convex lens in the collected materials, which would save a lot of effort.

However, when Shi Jian came to the gate of the cottage, he was stopped by the guards.

"Principal, King Ji said that the epidemic has not improved, and no one can go out. All the personnel in the cottage must be quarantined for three days." A tall and thin guard said to Shi Jian.

Shi Jian couldn't help but sneered when he heard the words, and said, "Quarantine? Another three days? Hehe, it's really good enough, I can even think of this, I'm convinced!" After finishing speaking, he turned around and walked towards the tribal warehouse.

When he arrived at the warehouse, the old man who looked at the warehouse smiled and said to him: "I said, Xiao Shi, what are you doing here today?"

"Uncle Zhang, I want to go in and find something, do you think it's okay?" Shi Jian said politely.

"Hey, look at what you said, tell the uncle what you want, and I'll get it for you." Old man Zhang didn't change his smile.

"I'll look it up myself, you may not be able to recognize it when you're old." Shi Jian wanted to go in and look for it by himself.

"This is not acceptable," Old Man Zhang changed his smiling expression just now, and said sullenly, "King Ji said on purpose just now that no one is allowed to enter Curry casually now, so don't force Uncle Zhang and me to make mistakes."

Shi Jian raised his eyebrows, and then said calmly: "Then how about it, you keep checking for me, is there a magnifying glass inside?"

"What is a magnifying glass?" Old man Zhang asked.

Shi Jian described the appearance of the magnifying glass to him, and then said, "Uncle Zhang, please excuse me."

Old man Zhang stood up and walked into the warehouse with his hands behind his back. After a while, he came back and said to Shi Jian, "No, I just finished reading it. There is no magnifying glass inside."

"That's hard work, you're getting old." Shi Jian said with a smile.

But when he turned around, the smile on Shi Jian's face could not be seen at all, only a layer of coldness remained.

Back home, Shi Jian was so angry that he walked back and forth in the room, cursing constantly: "It's too much! Can you show some face? You're just so bearish, why don't you be a leader!"

"What's the matter?" Feng Kuang came out of his room and asked with a tired face.

"Don't mention it, this Wang Lie is really going too far!" Shi Jian trembled with anger, and told Feng Kuang what happened in detail.

After listening, Feng Kuang frowned, and said to Shi Jian: "How can you agree to do this alone? Is it obviously a trap?"

"How could I have thought that this old boy would play such a hand with me? I just thought that a disheveled man like you would play tricks, but I didn't expect that Wang Lie, a simple man with thick eyebrows and big eyes, would also play such tricks ?” Shi Jian complained to Feng Kuang.

"Let's talk about it, don't bring me in, you know?" Feng Kuang said unwillingly.

Shi Jian said with a bitter face, "Just let me entertain myself, I'm going to have to make trouble later."

"You bastard, can you handle it?" Feng Kuang asked.

"There shouldn't be any problem. At worst, I'll melt the glass and make it myself." Shi Jian nodded and said.

"Then I'm going to have a rest, can you tell me when I'm helping?" Feng Kuang yawned and went back to the room.

Shi Jian sat alone on a chair, smoking a cigarette, while thinking of a solution.As a result, he found that the only way he could go was to melt the glass.

If you don't do it, you won't stop.Shi Jian went directly to remove a piece of glass from his window, smashed it, put it in a picnic pot, found another flat-bottomed stainless steel pot, and walked to the dining hall.

After entering the dining hall, Shi Jian found Wang An directly, and said to him, "Elder Wang, I'm here to beg you."

Wang An smiled and asked, "Principal Shi, what's the matter, just tell me, I will help if I can."

"No big deal, I just want to use your stove, do you think it will work?" Shi Jian pointed to the stove and said.

Wang An laughed, and asked in a low voice, "Is it related to Wang Lie's bet?"

Shi Jian didn't hide it, and readily admitted it.

When Wang An got the answer he wanted, he didn't stop him, and said simply and neatly: "That's fine, you can use it, but can't we delay cooking for a while?"

"Don't worry, there will be no delay." Shi Jian said with a smile.Then he remembered something, and hurriedly grabbed Wang An who was about to leave and asked again, "Is there any coal?"

In the past, coal was not used for cooking in the canteen, but firewood was used for cooking.But since Shi Jian found the coal mine, he also brought some coal over, but he doesn't know if there is any more.

"Coal, yes, but it's not much, I don't know if it's enough for you." Wang An said, leading Shi Jian to a corner of the kitchen, and pointed to Shi Jian the remaining bag of coal. Look.

Shi Jian was relieved as soon as he looked at it. Although the coal was not much, it was enough for him.

Seeing him nodding his head straight, Wang An knew that it was enough, so he left on his own, leaving Shi Jian alone to toss around.

After Shi Jian lit the fire, when the fire was red, he took off all the rings and put the picnic pot filled with broken glass directly into it.

The stainless steel picnic pot quickly turned red under the flames of coal, and the shattered glass inside began to soften little by little, but it was still a long way from completely melting.

Shi Jian brought over the wooden bellows used for cooking, and while pulling the bellows, observed the condition of the glass.

Watching the fire in the summer is really not a comfortable thing. Sweat drips from Shi Jian's forehead continuously, and his body has long been soaked in sweat.

But Shi Jian stared at the glass without blinking. Seeing that the glass hadn't changed much, he began to feel anxious.

"Can't it work?" Shi Jian muttered to himself, and his subordinates continued to speed up the speed of pulling the bellows.

Finally, under Shi Jian's expectant eyes, the glass began to melt, flowing in the picnic pot like syrup.

"Okay!" Shi Jian exclaimed happily.

The glass is melted, and all that's left is to make the convex lens.

Shi Jian's idea was very simple. He didn't plan to calculate the focal length, let alone make that kind of double-sided convex lens. He just wanted to make a convex lens with one side flat and the other convex, which would be more convenient.

He first scooped out some liquid glass with a spoon, poured it directly on the pan, let the glass naturally form a hemisphere, and waited for it to cool naturally.

He has made several such hemispheres, and plans to choose them at that time, and use them as the objective lens and eyepiece of the microscope.

The hemispherical glass obtained in this way also has the disadvantage that when the spoon is pulled away, a long glass strand is pulled out, which looks like it has a tail.

But this is not a problem, Shi Jian has to polish the glass anyway.

When Wang An came in and told Shi Jian to call it a day and hand over the stove to them for cooking, Shi Jian had already made more than 20 hemispherical glasses, which should be enough for him.

After dinner, Shi Jian selected a few glasses with smooth surfaces and a curvature closer to a sphere among these hemispherical glasses, and then began to polish them.

Grinding glass is a troublesome thing, because the hardness of the glass lies there, and the surface of the glass must be smooth after grinding, otherwise the resulting lens will not achieve the effect at all.

Fortunately, Shi Jian still has some sandpaper there, which can be used to polish the glass, otherwise, he will be helpless.

These sandpapers were all found by Shi Jian in the old district before. He put them directly in his hiking bag, but he forgot about them, so he didn't take them out and hand them in to the warehouse.

If he hadn't accidentally found these things in the interlayer, Shi Jian would have forgotten them long ago.

Although he doesn't know how many meshes of sandpaper should be used for grinding, he also knows that the larger the number of sandpaper, the smoother the surface of the object to be polished, and the slower the speed.

Based on this, Shi Jian first chose a small-grit sandpaper. Judging from the vague name on it, it should be [-]-grit.

But Shi Jian had never done this job before, and he made a big mistake as soon as he came up. He directly polished the surface of the glass with sandpaper, but was seen by Feng Kuang who came back, and made a fuss.

"You boy, why don't you ask my old man, can you polish it like this? It's just a joke!" Feng Kuang pointed at Shi Jian and said mercilessly.

Shi Jian was dumbfounded by Feng Kuang's words, and asked, "Then what should we do?"

"Add water, idiot!" After Feng Kuang finished speaking, he went into the house on his own.

Shi Jian blinked his eyes twice, and shouted behind Feng Kuang: "Old Feng, how did you know to add water? Don't you study chemistry?"

Feng Kuang turned his head and said disdainfully: "Boy, what's wrong with me studying chemistry? Is it still delaying my knowledge of this? Let me tell you, when I accompanied my classmates to get their glasses fitted, the optician used a water grinder to polish the lenses."

"Damn it! So that's what happened." Shi Jian said in a low voice.

Sure enough, after Shi Jian put a few drops of water on the glass, it became much easier to polish.He polished the glass surface in one direction, making it more hemispherical.

Then, Shi Jian kept changing the sandpaper with a larger grit, and finally used a piece of [-]-grit sandpaper, which was already the largest grit sandpaper he had.

After washing the powder on the glass and the sand left by the sandpaper with water, Shi Jian put the three convex lenses in the sun to dry, and the most complicated work was finally completed.

Although there were only three final qualified products, it took Shi Jian two full days of work, which made Xia Rou, who was watching the fun, lose interest and kept asking Shi Jian when he could finish the work.

Shi Jian had no choice but to explain his slow speed by working slowly and carefully. Although his hands were sore, he still pretended not to care.

Xia Qing originally wanted to take it over and help him polish it, so that he could have a rest.

But as soon as Shi Jian saw Xia Qing's onion-like jade fingers, he really couldn't bear to ask her to help, so he rejected her because she was pregnant and not suitable for this job.

And Fengkuang seems to be a bit of a dragon these days, and he often comes back very late.

This made Shi Jian suspicious all the time, and secretly said: "Did this old virgin, Lao Feng, go to some old lady's house to mess around? Can he still have this function at such an advanced age?"

Anyway, when the convex lens was finished, Shi Jian still had a sense of accomplishment.

But he didn't stop, but ran to Zhang Dongjie's house without stopping.

His purpose of coming here is very simple, that is to make a microscope frame and complete the last process.

As the saying goes, a good man can't stand three paoxi. Zhang Dongjie perfectly interpreted this sentence. He was also bedridden with dysentery a few days ago.

Seeing Shi Jian coming in, Zhang Dongjie froze for a moment, and immediately asked his wife to pour tea for Shi Jian.

After a few words of politeness, Shi Jian explained to Zhang Dongjie his intention for coming.

Zhang Dongjie said with a wry smile: "Principal Shi, it's not that I won't help you, but you can see that I am helpless now. Besides, Wei Qiang also went to the lime kiln and is not at home now."

Shi Jian originally thought that there was nothing wrong with Zhang Dongjie, but seeing this situation was also very helpless, he couldn't force him to get off the bed.

If the electricity can be solved perfectly now, he can operate the woodworking lathe by himself, which is not a problem for him who majors in mechanical design.

It is a pity that the electric power has not been solved yet, and the electricity generated is direct current, which cannot drive the lathe at all.

Shi Jian, who was full of melancholy, bid farewell to Zhang Dongjie, and met Wang Lie on the way home.

Wang Lie said with a smile: "Brother Shi, what's the matter, have you finished that microscope? Will it open my eyes?"

Shi Jian frowned, and retorted: "What is Mr. Wang doing in such a hurry? Are you planning to admit defeat early?"

Wang Lie was not annoyed at all, he smiled even brighter, and said: "I heard that you are almost putting on airs. It's a pity that Dong Jie has not recovered from his illness. Otherwise, you really won? What's the matter, there are no more carpenters in the tribe, brother, you'd better face reality."

Shi Jian's eyes narrowed when he heard the words, he suddenly understood, and said: "Mr. Wang is really good at it, I didn't expect it, I didn't expect it."

Wang Lie pretended not to understand what he said, and said, "What method? Don't say that, brother. Listen to my brother's advice, don't think about those useless things, isn't it good to live a peaceful life?"

"You have your pursuit, and I have my ideal." Shi Jian left without saying this.

"Principal Shi, can you take it out tomorrow morning? But there is only one night, why bother?" Wang Lie shouted loudly from behind.

"Then let's talk about it tomorrow morning!" Shi Jian's cold voice came over.
