Chapter 81: Do you know the magical object penicillin? A war artifact!
“Human and animal feces and urine contain saltpeter. Put the feces in a pottery jar, add a small amount of water, and then boil it in the pottery jar. The boiling time is relatively long, usually several months, and the final liquid is saltpeter liquid.”
“Another method is to use earth wall technology. First build an earth wall, then dilute the feces and urine with water and pour it on the earth wall. Use the action of nitrifying bacteria to generate nitrate alkali precipitation. Scrape off these nitrate alkalis and use them to refine earth saltpeter?”
“There is also a common earth method of refining saltpeter, which is to use saltpeter resources in nature. This method usually involves digging the foundation soil of old houses or soil in specific locations, and extracting saltpeter through boiling and filtering.”
At this time, Ye Ling couldn’t help but look at the people in the village:
“Can you often see some small white particles on the base of the old house?”
Although I don’t know why Ye Ling suddenly mentioned this, my second uncle and the others nodded immediately:
“Yes.”
“Well, those are also saltpeter soil.”
Everyone was stunned after hearing this. It turned out that this treasure was so close to them?
At first, they thought it was salt, but after tasting it, they found it was not at all.
“Wait, wait, Ye Ling, what nitrifying bacteria are you talking about? What are they?”
At this time, Huang Rong looked at Ye Ling curiously.
Ying Zheng and others heard the same thing. It was the first time they heard of bacteria.
“Bacteria, in simple terms, are those organisms that are so tiny that we can’t see them with our naked eyes. They are everywhere, and bacteria have a great impact on our human activities.”
“The reason why there are so many casualties among the wounded in the war is largely due to the infection caused by these bacteria.”
At this “six, seven, three” time, Ye Ling suddenly gained a large wave of emotional values.
Now Ying Yinman and others naturally feel their scalps tingling.
Everywhere? !
Thinking about these tiny organisms around them, they shuddered uncontrollably!
Not to mention Ying Yinman, Yan Lingji and others, even Ying Zheng and Zhang Han are the same.
Chilling!
However, Ying Zheng thought of the casualties of the soldiers that Ye Ling had mentioned, and immediately asked:
“How can the injured soldiers be treated for this bacterial infection?”
“If you want to treat it, you have to make penicillin.”
“Penicillin!?” Ying Zheng’s eyes lit up when he heard Ye Ling’s words!
He knew that if the soldiers were injured on the battlefield, the probability of death would be very high!
The best way is to prevent the soldiers from being injured, but how is this possible on the battlefield?
If there is a treatment method, how many lives of the soldiers can be saved?
Even Ying Zheng was so excited that his body trembled at this time.
Feeling the burning gazes of Ying Zheng, Zhang Han and others, Ye Ling explained helplessly:
“First, you need to collect a large amount of penicillium. The collection method is quite simple. Find moldy food at home and nearby, such as steamed buns, dumplings, fruits, etc. If they are moldy and green, they can be used.”
Ye Ling’s words stunned Ying Zheng and others.
They didn’t understand mold, but when they heard it was green, they understood it immediately.
But isn’t it broken?
Can it be used?
Of course, although he was confused, he did not interrupt Ye Ling, but remembered what Ye Ling said carefully.
“Then prepare the culture medium. The formula is to mix the juice made from rice and the juice made from sweet potatoes. If you already have corn, you can also use corn to boil the juice, and then put Penicillium into the culture medium and wait for seven days.”
“You can prepare some activated carbon during these seven days.”
“Activated carbon?” They knew about charcoal, but this activated carbon?
“The method of making activated carbon is to put hardwood or fruit shells into a porous metal container and burn them with an open flame until there is no smoke in the pot. Wait for the carbonized hardwood to cool down, then use cold water to wash away dust and impurities, drain the water, grind the charcoal into powder, and then air-dry the carbon powder. The activated carbon is ready.”
“By the way, this activated carbon can absorb impurities and odors in the water, making the water clearer and more transparent. It also has the function of absorbing toxins and odors, so it can be used to make gas masks.”
After hearing this, whether it was Ying Zheng or his second uncle, their eyes lit up!
Poison is definitely the most difficult to prevent!
But now, there is such an activated carbon with anti-toxic effects, so the life and death of the soldiers will be further guaranteed!
Although war and sacrifice are inevitable for the sake of great unification, every time Ying Zheng hears it, he will still be touched!
Those are all good men who followed him!
When the second uncle and his family heard that water can be purified, they thought of the water they pumped back from their homes!
It has a strange smell and is turbid. They have long been envious of the clear water in Ye Ling’s house!
In the future, their family will also have such clear water to use! ?
At this time, Ying Yinman, Yan Lingji and other women were staring at Ye Ling quietly.
It was obviously a calm attitude, but the words he said were so shocking!
“Follow the steps of penicillin extraction, take a clean container, preferably glass, that is, glass, if there is no earthenware jar, it will be fine, but it is not easy to observe. Put a piece of cotton at the mouth of the funnel and filter the culture solution into the earthenware jar through the funnel.
“Pour three times the amount of vegetable oil in the culture solution into the earthenware jar and start stirring. Stir until the liquid in the earthenware jar is divided into three layers. This is why the container needs to be transparent. If it is not transparent, you can’t see it, and you can only rely on experience.
Then carefully scoop out the top two layers of liquid, leaving only the water-like substance at the bottom. The difference between water and oil is still very obvious. ”
Ye Ling paused for a moment, and Ying Zheng and the others nodded when they heard it.
“Then add the carbon powder prepared in advance until the carbon powder absorbs all the liquid.”
“Wash the charcoal with distilled water, a little less water, then inject acidic water, and then inject alkaline water. The obtained liquid is filtered once with a funnel with cotton, and the obtained liquid is the penicillin solution.”
Seeing the clear eyes of Ying Zheng and the others, Ye Ling knew that they didn’t understand what acidic water and alkaline water were.
Sure enough, when they asked, they thought that acidic water was water that tasted sour.
Ye Ling roughly talked about the methods of making acidic water and alkaline water, and then distributed the grilled skewers to everyone.
Ying Zheng and the others also took a break,Recalling what Ye Ling said again in his mind.
After eating the skewers, he continued to grill again:
“Drop the penicillin solution into the prepared staphylococcus culture dish, cover it and wait for a few days. If a circle appears around the solution, it means that the penicillin extraction is successful. If there is no change, you can only try again.”
“By the way, remember to do a skin test when using penicillin! Although it is a miracle drug in a sense, it can also cost lives if you are not careful.”
Ye Ling explained what the staphylococcus culture dish is and what the skin test is.
After thinking for a while, Ye Ling said again:
“There is another way, but it takes a long time.”
“Please speak.” At this time, Ying Zheng looked like he was being taught.
This made all the villagers stunned.
“Put the mustard in a large jar, expose it to the sun and dew, let it mold, and when a three or four centimeter long green mold grows, seal the jar, dig a pit and bury it, and dig it out after a few years.
At this time, the mustard has completely turned into water, and the mold has disappeared. The remaining juice is the old mustard brine, which contains a large amount of penicillin.”
Ye Ling thought about it, and then spoke again:
“Penicillin has not been produced at this stage. You can use honey instead. Honey can trap bacteria and absorb their water, causing bacteria to die of thirst.
In addition, honey also contains an antibacterial mold that has the function of inhibiting bacterial reproduction and even killing bacteria.”
Ying Zheng, Huang Rong and others were stunned when they heard this. They didn’t expect honey to have such an effect?
“Some plants also have the function of antibiotics, such as mugwort, ginkgo, aloe, gentian, etc.”
Ying Zheng, Zhang Han and others all remembered it in their hearts.
And those guards of Ying Yinman had already started to record it with pen and paper.
These are all priceless treasures!
Then, Ye Ling simply talked about how to avoid bacterial infection.
It’s nothing more than using clean gauze and sterilizing the knife used to cut the wound. (To read the best novels, go to Faloo Novel Network!)
The simplest way is to boil it in hot water, roast it with fire, or use high-concentration alcohol.
Ying Zheng and the others were still stunned by Ye Ling’s words.
It turns out that doing this can greatly reduce the risk of infection!
“Okay, that’s all. Let’s talk about the bacteria again. Don’t be afraid. After all, we will be called big bacteria.”
Although Ye Ling said this, everyone still felt terrified.
“Do you know that our winemaking success is also due to the help of these bacteria.”
This made everyone stunned for a while, looking at Ye Ling with a true or false expression…
“And the production of food also requires these bacteria, such as cheese and yogurt.”
Sure enough, when they heard Ye Ling say that it can also be used to make food, everyone was not so scared.
When Xiaobao heard about the delicious food, he looked at Ye Ling with bright eyes:
“Brother, are you curious about what the cheese and yogurt taste like?”
Hearing what Xiaobao said, Ying Yinman and others all smiled, this little rascal.
However, they were indeed curious.”Want to know?”
“Yeah, yeah.” Everyone nodded seriously.
“Then think about it.”
“Ye Ling!” Seeing everyone as angry as a pufferfish, Ye Ling couldn’t help but laugh:
“Okay, I’ll make it for you to try when I have time.”
“Yeah!”
“Oh, by the way, these saltpeters are also the raw materials for making matches, pyrotechnics, black powder, glass, food preservatives, etc.”
Since it’s all mentioned, Ye Ling just continued.
“Pyrotechnics? Black powder? Glass?”
Ying Zheng didn’t have any interest in the first two, but he often heard about glass from Ye Ling, so he was very curious about it.
But as Ye Ling explained, Ying Zheng immediately changed his mind!
“Fireworks can be made from pyrotechnic powder, which is very beautiful.”
Seeing the confused expressions of the crowd, Ye Ling explained again: “For example, it is like a flower formed by flames. Imagine what a beautiful scene it would be when it blooms in the dark night sky?”
“Wow~” Xiaobao’s eyes sparkled immediately after hearing this.
After all, it is very beautiful when you think about it this way.
The others roughly imagined it at this time, and also looked at Ye Ling expectantly.
“I want to see it!” Ying Yinman looked at Ye Ling seriously and eagerly.
“I want to see it!” The two little ones also looked at Ye Ling seriously at this time.
The eyes of others were the same.
Ye Ling:
“Okay, I will make it for you if I have the materials.”
“Yeah!” Seeing their bright smiles, Ye Ling also smiled.
Well, it would be quite good to set off these fireworks during holidays.
There were few entertainment projects in ancient times, and it would be lively and lively with this.
And what would others think when they saw this?
A miracle has come?
Just think about it, that’s a lot of emotional value! []
Speaking of emotional value, explaining these now also gained a lot of emotional value!
“What about black gunpowder?” Huang Rong asked again curiously.
“Explosives!”
“Explosives?” It was another unfamiliar word that everyone didn’t understand.
“Substances that can burn violently (i.e. explode) in a very short time, to put it more simply, if there is enough explosives, it will only take a moment to dig a mountain or dig a sea.”
As soon as these words came out, everyone fell into a silence that could be heard even if a pin drop was heard.
It was nothing else, it was too shocking!
“How to make this thing?” This time, it was Ying Zheng who spoke.
After all, if this explosive could be obtained, with such a terrifying power, how far would the real unification of the world be?
Hearing Ying Zheng’s question, Yan Lingji, Duanmu Rong and Huang Rong’s faces all changed.
They were not native to the Qin Dynasty, so they naturally knew what would happen if Ying Zheng got the explosives.
Ye Ling did not hide this.
As for what items that should not appear appeared in that era, in some novels, those time travelers clearly knew the principle of explosives, but they were unwilling to make them for some reason.
They said that it would lead to the collapse of civilization, and they were more willing to sacrifice soldiers to unify the world.
For Ye Ling, it does not exist.
“In fact,Very simple, one saltpeter, two sulfur, and three charcoal. ”
“One saltpeter, two sulfur, and three charcoal.” After hearing this, Ying Zheng couldn’t help but repeat it again.
[Ding! Congratulations to the host for getting 940 points of excitement for Ying Zheng!]
If it is really as Ye Ling said, then this gunpowder will be his weapon of killing to unify the world!
He wants to make the world open up before they surrender!
He wants to end the war in the world and complete the great unification.
Let the people of the world have food in the morning and food in the evening.
To create a real country and home!
This is the ideal that Ying Zheng pursued all his life!
