Marin, no matter what the Genes think, he just explains the truth:
"My teacher once traveled to Kafa Port and talked to local elders, and learned the truth about that year. However, when traveling to Asia, the teacher discovered a very strange phenomenon - although there were records of the outbreak of the Black Death in the local area, it was not as frequent as ours. Then, he conducted an investigation in Persia and Turkey for more than ten years, and finally found the secret..."
"What's the secret?" Everyone raised their ears curiously. Because the Black Death is a terrifying existence than smallpox. It is also very important to avoid the Black Death.
"The teacher found that women in the Middle East are trapped at home and are not allowed to go out, so many women like to keep cats to accompany them. And these cats are not only those mistresses who relieve their boredom, but also the killers of mice, destroying the mice in the Middle East's homes... "
"Have a cat...but isn't a cat an unknown incarnation?" Emperor Maximilian I asked in confusion.
"This is the problem..." Marin gave the emperor a thumbs up in her heart - a very good supporting actor!
Marin explained:
"The teacher found that the reason why cats are considered unknown is that on spring nights, cats make terrifying and annoying screams when courting. In a quiet night, this kind of screams is indeed terrifying, like a devil. But in fact, it is just those cats who want to find a breeding for the opposite sex..."
Speaking of this, many people present laughed... Since ancient times, men have been excited to hear this topic...
Marin waved his hand and said:
"Don't laugh, I'm telling you serious! This kind of cry is actually just a normal courtship confession for cats, similar to what humans say, 'Girl, I love you'..."
Everyone laughed louder, this topic is a bit exciting...
"It's just that the cat's courting sounds a bit terrifying, and it's really a quiet night, so people misunderstood it as a demon. However, as everyone knows, cats are active in the middle of the night, and there is no way. Dogs are both pets, but because they mainly engage in the daytime, although they also have screams, they do not affect people's lives. After all, the cat's cry in the middle of the night is a bit out of place. And it's just a bit ugly..."
"But, Grand Duke Marin... Oh no, His Majesty Marin, what does this have to do with the Black Death?" asked the French envoy Dolby.
Marin glanced at Dolby and explained:
"I just said that the Black Death is called the plague, which is transmitted through fleas on mice. If there are enough cats and eat up all the mice, will the Black Death have no way of contagion?"
After hearing this, Dolby nodded:
"It seems to make sense...but, can it prove it?"
Marin shook his head and said:
"I can't prove it because it's too dangerous. After all, the Black Death is different from smallpox. If smallpox is grown, you won't be afraid of smallpox. However, after the Black Death patient survives, he will still be dangerous next time he encounters the Black Death. Therefore, I dare not prove it randomly."
Then, Marin said:
"But, what I want to tell you is that Beihai Kingdom has started raising cats long ago. Every granary in Beihai Kingdom will raise some cats, specifically to deal with mice that steal food. Therefore, our granary has less food loss. Moreover, eliminating mice will also help curb the spread of the Black Death."
"Everyone knows how dirty the bottom cabin is on the merchant ship. Many merchant ships live in the bottom cabin. And the Genea merchant ship who returned from Kafa brought the rats back, which led to the spread of the Black Death."
"In fact, the Black Death can cause such great harm in Europe because we misunderstood cats and drove them out or even killed them. In this way, mice are flooded and the spread of the Black Death is even more rampant. Therefore, tens of millions of people died of the Black Death in Europe..."
"The teacher's notes record that in some cities where there are many cats, the Black Death has never been on the voluntary outbreak, unless it is spread from outside. The reason why Europe could not stop the Black Death before was because cats were expelled and mice were rampant, which made the Black Death flood so quickly."
"So, in order to prevent those merchant ships from bringing back the plague from the outside world, I have ordered that every merchant ship sailing overseas must keep a cat, specifically used to deal with the mice on the ship, so as to avoid the re-spreading of the Black Death. Without the mice, the Black Death will have no source of transmission."
"Of course, raising a cat to kill mice is just the first step. In addition to eliminating mice, the teacher also advocates paying attention to hygiene in his notes. For example, it is necessary to clean up all the feces in the city and transport them out of the city to avoid the breeding of flies. The teacher records that not only mice are prone to breeding problems, but flies that parasitize in feces that can be seen everywhere in the city are also prone to plague..."
"So you clean the city of Beihai Kingdom and collect all the feces and transport them out of the city?" The supporting actor Maximilian I stood up in time at this time.
Marin nodded and said:
"That's right, that's it. Flies are grown by maggots parasitic on feces. Their claws are filled with unclean things such as feces. If flies bite the feces that can be seen everywhere in the city, then go and bite the white bread you eat..."
Speaking of this, many people probably think of something, and their faces look ugly... because, the possibility is really high...
Marin ignored whether they were disgusting or not, but continued:
"If a fly has bites something that has plague, then you will bite the food you eat. Eating this food will easily lead to illness or even plague..."
Many people changed their faces, and they were the "supporter" Maximilian I, he hesitated:
"It's not that we don't want to do this, but if we start collecting feces, the labor cost is very high! If the city is clean, God knows how much it will cost..."
This chapter is not over, please click on the next page to continue reading! For the famous poor emperor, money is the biggest problem...
Marin really wanted to tell them that feces could be pulled out as fertilizer, just like the Ming Dynasty. However, this is to cultivate competitors, which can easily cause grain prices to collapse. Marin made a fortune by making money, so how could he tell the secret?
However, he thought of a solution:
"Everyone, don't you know that feces are piled up in the septic tank. Can nitroso soil be collected for refining saltpeter? As long as you build a nitroso collection center outside each city, dig out multiple square pits, specifically for collecting nitroso soil. As we all know, the price of saltpeter is also very short. This alone can recover the labor cost of collecting feces in the city..."
"This is a good idea..." the emperor nodded, but asked again:
"Nite soil frosts usually occur when the weather is relatively cold. How to collect nite soil in warm weather such as summer and late spring and early autumn?"
At this time, the method of collecting soil and nitrogen is still very backward. I only know that when the weather is cold, collect the frosted nitrogen soil in the corners of the cesspool and scrape it down and refine it.
But they didn't know that in later generations, there was no need to worry about collecting soil and nitrogen, and they directly mixed the soil with urine to react naturally. Then, they were directly refined. In this way, the proportion of collecting saltpeter would be higher. The proportion of frosted nitrogen soil hanging in the corner of the wall was actually relatively low, so it could only be considered as part of the nitrogen.
But Marin would not tell them the complete method of extracting soil nitr, so he gave a suggestion:
"Let's do this. If you have a city close to the Rhine River, in summer, late spring and early autumn, you can't extract nitroso soil, put it in a barrel and ship it to Beihai. I'll buy it! In this way, you don't have to worry about not being able to recover the labor cost of collecting feces when the weather is warm!"
Marin actually had long coveted a large amount of feces from various countries. Unfortunately, he could not find a reason to acquire them before. Moreover, it could easily arouse suspicion from other countries. However, now he has found a reason...
"Do you have a way to collect soil and salt when it's hot?" "Supporter" Maximilian I asked in confusion.
Marin had a solution, so he answered with great confidence:
"Yes, I have bought Iceland from Denmark. It is cold all year round, but it is not cold until it freezes. It is the best climate for collecting soil and silt. As long as the feces are shipped to Iceland to accumulate, a lot of soil and silt will definitely be scraped out in a few days. Moreover, there are not many people in Iceland, and there are no fears that the island will be filled with feces and will be too dirty. In addition, the place is a little cold and flies will find it difficult to survive..."
When everyone heard this, they thought it made sense. After all, Iceland has also been heard of, saying it is Iceland, but only the inland is colder and the coast is still not frozen. The temperature is probably equivalent to the frost in the middle of the night in late autumn. It is most suitable for oozing out of earth. It is indeed very good.
But they didn't know that Marin actually wanted to use this method to deceive the fertilizers from various countries. After all, compared with the little bit of earthy frost powder, the fertility of manure is what Marin values ​​the most.
Moreover, now Marin has no ability to synthesize ammonia. If you want enough nitrogen fertilizer, you can only deceive other countries' feces...
The lies of using Iceland's climate to collect soil sauerkon are also seemingly free of loopholes, very reasonable, so reasonable that no one doubts. Moreover, the Beihai Kingdom does need saltpeter very much. After all, the Beihai Kingdom's military firearms account for a high proportion.
Therefore, while introducing the causes and prevention methods of the Black Death, Marin, the new king, actually talked with the monarchs and envoys present to the business of collecting manure...
Marin repeatedly emphasized:
"You must bring wet feces with urine, don't dry feces!" The reason for this is that saltpeter costs mostly come from urine, not feces. He was afraid that the people selling feces in various countries are too heavy, so he sold them to him after they were dried.
To this end, Marin also took the initiative to express his willingness to provide sealed feces to fill them with damp poop...
As for the purchase price, it is almost the labor required for cities to collect feces. The labor cost in Germany is only 2 per day, so there is no need to pay much.
Those monarchs and great nobles would not care about this little money, as long as they did not have to pay the wages of the workers who collected feces themselves, it would be fine.
In this way, a good scientific lecture on how to deal with the Black Death was silly made by Marin, a vulgar guy, and turned it into a negotiation meeting for collecting manure...
