The daily routine of the ancient imperial examination

When everyone saw General Zhou's reaction, they all understood the ins and outs and began to curse.

"These barbarians! Son of a bitch! Do all these immoral things!"

Lu Xiuyuan didn't expect that the plague that suddenly broke out at Longmen Pass was man-made, and he didn't expect that the hooker on the opposite side would be so vicious.

Now that there was a snowstorm and the losses were heavy, I didn’t have a good rest and rest. Anyway, I was thinking about plundering others to meet my own needs every day. I couldn’t attack the city, and I even did such indecent tricks as transporting frozen dead livestock over to poison!

It can only be said that they are indeed barbarians, a group of creatures whose brains have not fully evolved.

Everyone pointed at the back of the snow mountain and cursed there.

Lu Xiuyuan saw that it was not a problem for everyone to just stand there and get angry, so he suggested: "You can't hear them scolding here, why don't you follow the water and look up the mountain before the sun goes down? Are there any dead bodies, and when the sun is about to set, we can quickly set up a tent and discuss the solution later?"

General Zhou felt that this proposal was very good. It was not easy to go up the mountain once, so it was better not to waste time, so he made a mark and directed everyone to move on.

A group of people searched for more than half an hour across the mountains, and did not stop until the sun was about to set.

General Zhou took a look at his current location, and saw that the ground around him was flat, so he waved his hand to signal everyone to stop, "Let's not look for it now, let's go find some firewood, and rest here for the night temporarily today."

After receiving the order, some went to find firewood, and some prepared dinner. Everyone had a clear division of labor and performed their duties. The scene seemed orderly.

Lu Xiuyuan saw General Zhou planting wooden stakes to set up a tent. Seeing that the tent was a little big, he planned to go over and help, but the other party waved his hand and refused.

"Lu Xiucai, you scholar, after running with us for such a day, you are probably tired, so just sit there and have a good rest."

"It's not tiring to help get the tent down." Lu Xiuyuan said helplessly.

Zhou Shenjiang stopped what he was doing, thought for a while and said, "Since Lu Xiucai can't be idle, why don't you sit over there and think about how to deal with the follow-up issue of disposing of the corpse tomorrow."

Speaking of this, Lu Xiuyuan suddenly fell into deep thought.

The corpses in the pool decay and breed bacteria and microorganisms. Even if the corpses are disposed of, the water in the pool will be polluted and bacteria will still exist.

The ancient drinking water disinfection method generally uses several layers of filtered and precipitated purified water. Even if there are items such as alum and charcoal that can absorb macromolecules in the pool, the microbial germs inside cannot be absorbed by filtration.

In a situation like this, it would be great if there was a modern bleach, just sprinkle a small bag directly, and the disinfection and sterilization will be completely resolved.

Lu Xiuyuan thought about the possibility of making beautiful guns in his mind.

The main component of bleaching powder is calcium hypochloride, and the production method is generally to put the bleaching powder into a calcium hydroxide solution to generate calcium chloride and calcium hypochloride.

Calcium hydroxide solution is also lime water, and the best extraction can be extracted by reacting concentrated salt and manganese dioxide, but there is no laboratory equipment here, so it is a bit difficult.

In addition to this, sodium hypochlorite can also be produced by electrolyzing salt water, but there was no electricity in ancient times, and thinking went to a dead end again.

Bleaching, disinfection, and ozone disinfection are excluded, and boiling disinfection is the most convenient and economical. However, because this is ancient times, the environment of Longmenguan is so harsh, and the people can't even keep warm, let alone drink boiled water.

Therefore, the water pool must be thoroughly disinfected and sterilized.

Since several commonly used methods are limited and cannot be done, then change your thinking and continue thinking.

The living environment of bacteria and microorganisms generally contains amino acids, especially in rotting corpses where there are more proteins, and bacteria are most likely to breed. Then add strong alkali to the pool water, and the alkaline environment can destroy the cell walls of bacteria, making their proteins Denaturation can also achieve the purpose of killing bacterial microorganisms.

It can turn water into a strong alkaline environment. What can be thought of in ancient times is quicklime.

Lu Xiuyuan found a stone, and calculated the approximate volume of the pool of water he saw earlier, and how much quicklime should be prepared according to the proportion.

After he calculated the result here, the soldier who picked up firewood over there also came back, and everyone lit up a fire and started to bake steamed buns to eat.

The steamed buns made of black noodles may not look very beautiful on the outside, but when they are put on the fire, they are burnt and burnt, and they taste extraordinarily delicious.

After dinner, Lu Xiuyuan sat cross-legged in front of the fire and listened to General Zhou telling him about the war on the border. Apart from the Goudai tribe, there were several other barbarian tribes, and they were basically convinced by General Shi. Don't dare to offend easily.

As he was talking, General Zhou recalled the poisoning by the Goutai people, and immediately said angrily, "The Goutai people really have no conscience! When I go back and report to the general, I will destroy their tribe!"

As soon as these words came out, the other soldiers in front of the fire also echoed, everyone was very angry, and their sleepiness was gone.

Early the next morning, Lu Xiuyuan heard the voices around him, even though his eyes were sleepy, he still pushed himself to get up.

The chat last night was too exciting, he lay in the tent for a long time before falling asleep, which made him very listless after waking up.

Zhou Shenjiang next to him patted him on the shoulder considerately, "If Lu Xiucai is sleepy, I will go to sleep again, and I will call you after dinner."

"No, no, just walk around." Lu Xiuyuan quickly refused, with a somewhat impressive face.

Now that the source has been found, things will be much easier to handle. After breakfast, they found a few people to fish out all the corpses in the pool, dug a pit nearby and buried them, and checked the surrounding water sources again. directly down the snow mountain.

Back at Longmen Pass, Lu Xiuyuan did not go to find Dr. Xu, but followed them to the General's Mansion.

After General Zhou finished reporting the news, General Shi came to ask Lu Xiuyuan.

"Just now I heard General Zhou say that quicklime is needed to purify the water source, and alum can make the water of the Yellow River clean. Couldn't it purify the water in the pool on the snow mountain?"

Lu Xiuyuan thought for a while and replied: "Alum can only absorb some relatively large impurities. In fact, there are many small germs in the water that our eyes cannot see, and they are the diseases caused by them. Quicklime is alkaline and can Destroy the living environment of germs, thereby killing them."

General Shi didn't quite understand it, but he probably understood what the other party meant, so he said, "Then see how much quicklime and alum you need, report it here, and let them go up the mountain again tomorrow morning."

Lu Xiuyuan thought about the water pool where the dead animals were soaked, plus several other small water pools, calculated the cube, and reported a number.

After General Shi heard this, he couldn't help but patted Lu Xiuyuan on the shoulder, "Okay! I'm going to send someone to prepare it now."

After speaking, he didn't stay with Lu Xiuyuan for too long, so he drove him back to rest.

Lu Xiuyuan didn't try to be brave. After climbing the snow mountain for two days, he was very nervous. Now he is indeed a little tired.

After leaving the General's Mansion, he wandered slowly on the street looking for Dr. Xu.

After receiving and treating patients during this period, Longmenguan is quite different from when he first came here.

There are no sick people lying on the street, and no children standing on the street screaming and crying. There is a scene of stability and harmony on the street.

Lu Xiuyuan swayed slowly like this, and came to the northeast corner of the city gate, because now the patient has mostly recovered, Dr. Xu and the others are not as busy as before.

Seeing him coming, the other party was surprised and said: "The general's mansion sent a letter saying that you went up the mountain? Didn't you come back so soon?"

Lu Xiuyuan told Dr. Xu what happened when they went up the mountain yesterday, and the doctor immediately blew his beard and stared at him.

"This Goutai clan is too inhuman! How can you do such a shameful thing!"

Lu Xiuyuan saw that the other party was quite old, so it's better not to get too excited.

"Doctor Xu calm down, General Zhou has already reported the matter to General Shi, and they will deal with it later, so don't worry about it, it's not worth it to be angry."

Dr. Xu snorted coldly, but seeing Lu Xiuyuan's uneasy expression, the other party couldn't help but cared and said, "I see that your expression is uneasy, so why are you here if you don't come back and take a good rest?"

After saying that, she wanted to drive him back to rest.

Lu Xiuyuan hurriedly stopped him, "Don't, don't, Doctor Xu, I'm here to see you."

The other party cast a puzzled look.

Lu Xiuyuan rolled up his sleeves and lifted his trouser legs, "I went out and tossed around, and I felt not in a good mood after being blown by the wind, please Dr. Xu give me two needles."

Dr. Xu stroked his beard when he heard the words, "It's okay for me to get acupuncture. Have you read all the meridian diagrams I gave you before? What parts like you need acupuncture? What are the effects?"

Lu Xiuyuan was a little embarrassed, he just glanced at the book Dr. Xu gave him, and put it under the Annotation of the Four Books.

But fortunately, he has a good memory and has more experience in previous lives, so he picked a few universal health care acupuncture points in his mind that can't go wrong.

"Guanyuan acupoint, Dazhui acupoint, Zusanli acupoint... Guanyuan acupoint nourishes kidney qi..." He said a few words casually, mentioning that he still had the effect of remembering.

Dr. Xu frowned slightly, "I didn't say it carefully enough. You can tell that you didn't read the book carefully at home. As for the efficacy, you must read it carefully when you go back! Study hard! You know!"

What the other party said was serious, Lu Xiuyuan could only nod in response, let's push back the sleep time at night.

Take advantage of the opportunity now, if you can learn more, learn more, and don't regret it when you don't have the opportunity in the future.

Although Dr. Xu was not satisfied with his answer, he still helped him with acupuncture.

It's just that after acupuncture for a quarter of an hour, Lu Xiuyuan felt much lighter.

In the early morning of the next day, he came to the General's Mansion in high spirits again, waiting to continue to go up the snow-capped mountains with General Zhou.

The other party was a little surprised when he saw him, "Why did Lu Xiucai come here? Didn't you tell us the operation method? It's enough to have a few brothers on the mountain today. You can go back and rest."

Lu Xiuyuan murmured in his heart, no matter what other people promised, he still wanted to see the water in the pond being disinfected with his own eyes, so that he could feel at ease.

In short, under his struggle, he once again boarded the snow mountain with everyone.

Because I just climbed the day before yesterday, I have experience in going up the mountain today, and I saved a half of the time compared with the last time, so I came to the water pool.

General Zhou Shen commanded the soldiers to pour quicklime into the pool. When it hit the water, a lot of heat was released, and the surrounding pool water also rolled.

I took the long wooden stick prepared in advance and started to stir, the whole pool water became very turbid.

Looking at the gray pool water, General Zhou was a little puzzled, "After the water is drained, can I still drink it?"

"General Zhou will wait first."

The current pond water is combined with quicklime to form calcium hydroxide, which turns into an alkaline liquid, which is naturally undrinkable.

Everyone sat in front of the pool and waited for a while, and when the water temperature cooled down, they added alum.

After stirring and sedimenting again, the pond water became clear to the naked eye.

The author has something to say: alum water purification also has disadvantages, it’s too late today, let’s talk about it in the next chapter~
