In any case, the Black Death (bubonic plague) was the first plague in Europe, and smallpox came second. But to be honest, smallpox was force majeure, and the Black Death was caused by the Europeans themselves.

The so-called plague was naturally caused by rats. And why is the plague so big in other countries, but the bubonic plague (Black Death) in Europe is so ferocious? Because the Europeans themselves died and drove out the cats!

Just because cats like to make mournful sounds that resemble the cry of babies on spring evenings (courtship sounds), stupid Europeans consider cats to be ominous creatures. Then, these rat catchers were banished, and even killed.

Without the suppression of cats, rats were rampant throughout the Christian regions of Europe, and the plague was naturally very prone to outbreaks. Therefore, Marin felt that the Europeans were killing themselves.

Originally, he didn't want to care, but in order to gain some prestige and make some name for the newly established "Save the Knights", Marin took out this set of theories. In fact, Marin has long come up with this set of theories. However, it is only promoted in the North Sea country. It's not that he doesn't want to promote it all over Europe, but people don't believe it.

Moreover, cats are considered to be the embodiment of bad luck, and if they speak for cats, they will be attacked as "protecting evil".

But now it was different, because of the proposed solution to smallpox, Marlin was now an authority on medicine and had a very good reputation. At this time, he stood up to help the cat speak, and if nothing else, at least he would not be slandered. Because, at this time, others have no face to slander a hero who solved smallpox.

Of course, Marin didn't say that it was his own opinion, but still pushed it to his legendary teacher "Albert Einstein......

"Some time ago, I sorted out the tattered notes that my teacher left me, and I made two major discoveries. The first one, as everyone knows, is the way to resist smallpox. The effect is already clear to all of you......"

Speaking of this, the monarchs and envoys of all countries present nodded one after another. Moreover, they are full of admiration for Marin's legendary teacher "Einstein".

Although many people don't like Marin, the "nouveau riche" in the aristocratic circle, everyone has to admit that Marin, the lord of the North Sea Kingdom from a humble background, is the most outstanding young talent in Europe.

However, the investigation of various forces shows that before meeting the great sage named "Einstein" and accepting his teachings, Marin was a pure 16-year-old ignorant teenager. Even, a little silly. Because he was cheated out of his travel money, he almost starved to death, and was forced to sleep in a haystack next to the church......

In other words, all the changes and rise of Marin only happened after meeting the legendary "St. Einstein".

Therefore, everyone present had no doubts about the ability of the great sage, and they were also extremely jealous of Marin's good fortune - a stupid boy who had been taught by the great sage for a month had such a big change, and even if these people who were smarter than the stupid boy had accepted the guidance of that great sage...... Isn't that heavenly?

Marin cleared his throat and continued:

"In addition to the method of fighting smallpox, there is another thing recorded in the note, something that everyone is concerned about—the origin of the Black Death, and the ...... of how to fight it," Marin said slowly.

"Coax—" The whole square was boiling, and even Julius II stood up excitedly and asked:

"Is there a solution to the Black Death?"

Marin shook his head and said:

"Not for the time being, but there are certain preventive measures, so let me first introduce you to the origin of the Black Death......

"The Black Death, whose real name is 'plague,' is a plague that is spread by fleas on rats. As we all know, fleas are little devils that live by parasitizing people and animals, and by sucking blood. And after some rats have a plague on them, fleas suck their blood and then jump on people and bite them...... At this time, the fangs of the fleas have been infected with this plague, and if they bite a person, they will also be infected with the plague, which is the Black Death......"

"I see...... So, where did the Black Death come from? Emperor Maximilian I asked curiously.

"East!" Marin goes on to explain:

"You should remember the Tatar invasion of Europe hundreds of years ago, right?" Europeans do not know about Mongolia, only about the Mongols and the Tatars of mixed white descent.

"You mean, the Black Death was brought by the Mongols?" Maximilian I was surprised.

Marin nodded and said:

"Yes, my teacher has traveled to envoys, and has traveled to the far East to investigate the matter. He discovered that the first bubonic plague in Europe had broken out in the Crimean Khanate in the port of Kaffa. In that year, the Tatar army of the Kipchak Khanate besieged the Genoyan-occupied port of Kaffa around 1347, but was unable to capture Kaffa. ”

"At this time, the Black Death broke out in the Tatar army. So, the Tatars used trebuchets to throw the dead of the Black Death into the city of Kaffa, causing the Black Death to break out in the city of Kaffa. ”

"Subsequently, the Genoese mercenaries in the city were forced to evacuate and return to Italy, bringing this terrible Black Death back to Western Europe......"

"Protest, this is a slander against the Republic of Genoa!" The Genoese emissary, Maccini, protested. If people thought that the Genoans were responsible for the Black Death, Genoa would have a bad reputation. You know, the Black Death killed tens of millions of people in Europe. In many countries, the population has only recovered now, and it is the same as before the Black Death.

Marin shook his head and said:

"I don't slander you, the teacher's account says that the rats with the virus arrived in Italy hiding on a Genoese ship. The Black Death then broke out first in Italy, first in Messina, where the merchant ships returning from Genoa docked, then back in Genoa and then detonated, spreading throughout Western Europe......"

Julius II thought for a moment, then nodded:

"Yes, the Black Death did occur after 1347, and it did break out first in Messina and Genoia......"

This sentence is equivalent to confirming the name of the Genoans who brought back the Black Death. Suddenly, the hateful eyes of the audience were turned on the Genoean envoy Maccini. In fact, Europeans also knew that the Black Death broke out in Italy first. However, there is no specific conclusion as to who brought it back. Because, everyone did not know what happened in Kaffa, and the Genoyans kept it a secret for themselves. Messina and Genoa were both famous merchant ports in the Middle Ages, with not only Genoa's own merchant ships docking, but also from Venice, Pisa, and Siena

"Slander! It's all slander! Marchini exclaimed.

Genoa, once a commercial republic on a par with Venice, is now in decline and has to survive with French thighs. But if their reputation is completely stinky, who will do business with them in the future?

In fact, the Genoese knew all too well that they had brought the Black Death back to Europe. However, what happened in Kaffa in those years was not known to other countries, and the Mongols of the Kipchak Khanate, who were not familiar with European countries, would not speak. Therefore, although everyone has always suspected Genoa, the Genoans flatly denied it, and threw the pot on the heads of other Italian commercial countries, and Venice also became the object of suspicion. Therefore, by muddying the waters, no major incident occurred in Genoia. If it had been confirmed that the Genoians were responsible for the outbreak of the Black Death, Genoa would have been wiped out. And now that Marin has broken the news, although people are not so angry, it is certain that they are hostile to Genoya...... Didn't you see that all the monarchs and envoys in the audience looked at Machini with hostile eyes......

As the old rivals of the Genoeans, the Venetians were happy to see that Genoa was deflated. However, because of the malicious spread of smallpox by the governor of Dalmatia, Toleni, the Venetians did not dare to jump out. Now, the two commercial republics are also considered brothers. But to the delight of the Venetians, because after Marin revealed the secret of the Black Death brought back by the Genoeans, the crime of the Venetians bringing back smallpox was temporarily covered up by the "big news" of the Genoais. It seems that Marin is still a good friend of the Venetians, helping Venice divert everyone's attention...... Charlotte, the messenger of Venice, looked at Marin with kindness and gratitude......
