For the suggestion of the pope's father-in-law, Marin was actually a little unhappy. Because, smallpox is a big killer. If the cowpox method to eradicate smallpox is handed over so easily, smallpox will not be able to make a fuss in the future.

However, the violent reaction of the Holy See this time also made Marin aware of a problem - to spread smallpox to deal with the enemy, and while harming the enemy, it is also easy to make himself a street rat that everyone shouts and beats. It may even be destroyed by the united efforts of angry nations.

Therefore, although he felt that it was a pity, after thinking about it for a while, Marin decided to accept the suggestion of the Pope's father-in-law and sacrifice the cowpox method in exchange for practical benefits.

However, he has his own views on how to do it. After all, he is the soul of a modern man who has experienced the hype of later generations, and Marin is more proficient in how to exchange the cowpox method for the greatest benefit than his own papal father-in-law.

So, at his suggestion, Pope Julius II first came forward in person and publicly prayed for all smallpox patients.

In addition, Julius II publicly offered a bounty throughout Europe - if anyone could find a way to defeat smallpox, he would not hesitate to give him a crown!

Julius II's attitude was unanimously respected throughout Europe, but no one thought that anyone could take the crown. Because, in everyone's eyes, smallpox is no different from death.

And, according to superstition, smallpox, like the Black Death, was God's punishment on earth, and what mortal could solve it?

Only a small number of people in the North Sea Kingdom know that this crown is for their Grand Duke Marin......

Because, although Marin kept it secret and did not disclose the role of cowpox, there are still a small number of insiders who know that they have been vaccinated with cowpox and can fight smallpox. For example, the core high-level leaders of the North Sea State, as well as some spies. Especially the spies who were sent to the endemic areas, Marin explicitly told them that they were already immune to smallpox, and they dared to return to Spain, southern France, and Italy.

However, there was a big mistake in the middle - a spy sent to Italy by the North Sea State probably had a cerebral convulsion, and he was actually dizzy, and planned to sacrifice the cowpox method himself and exchange the throne with the Pope......

As a result, this guy was naturally secretly disposed of by Julius II......

Just kidding, this was originally a crown for your son-in-law, and you, a subordinate, are actually trying to take the credit of your master? Besides, give you the crown, do you have land?

……

Subsequently, Julius II issued 12 edicts in succession, including a prayer for God to bless the people...... In short, a good pope who is desperate to save the people is played to the extreme......

At the critical moment, Marin finally stepped up......

Of course, Marin cannot directly say that he invented a way to combat smallpox. After all, this is too fantasy and does not fit the religious context.

Therefore, Marin still let the so-called "great sage" teacher Einstein who did not exist take the blame......

Marin said that the piety of His Holiness the Pope touched God. Therefore, God specially guided himself to look through the notes left by his former teacher, the great sage Albert Einstein, and found clues. After months of trying, risking my own life, and trying it myself, I finally found a way to fight smallpox - the cowpox method!

And in order to justify his papal father-in-law's inability to communicate directly with God, Marin said that he had asked this question in a dream, and the messenger of God said that the pope only administers the faithful, not the disease. Therefore, this matter needs to be told to the Holy See under the pretense of someone else's hand......

……

After all this tossing and flickering, the whole of Europe was in a stir - what? Smallpox, which represents the devil and death, was solved? Really? Moreover, this cowpox method is too weird, isn't it...... Really useful? Many people are skeptical......

But Julius II, who had already been infected with cowpox, showed the wound on his arm and said - this Pope has already taken the risk and tried it himself, no problem! Which of you will plant cowpox first?

In front of everyone's eyes, while others were still hesitating, Archbishop Giovanni of the Medici family, who had long consulted privately with Marin and Julius II, was the first to stand up - I come!

How could he miss this kind of good opportunity to brush up on prestige? Moreover, both the Pope and Marin had repeatedly promised that there was no danger, so how could he miss this opportunity?

If it weren't for the fact that the Pope had already planted cowpox, and if he planted it again, there would be a rejection reaction, and how could Julius II allow him to steal the show?

In full view of everyone, Archbishop Giovanni, the future Pope Leo X, bravely threw up his arms and shouted with his eyes closed:

"God is with us!"

Then, the people sent by the North Sea Kingdom took the cowpox from the smallpox cow and planted it on Archbishop Giovanni's arm in public......

The other archbishops of the College of Cardinals did not respond immediately, choosing to observe for a while......

Ten days later, Archbishop Giovanni was still alive and kicking, only slightly uncomfortable for a while. Then, dozens of cardinals of the College of Cardinals rolled up their arms and waited for the cowpox to be planted......

By the end of July, the clergy of Rome had been infected with cowpox and began to spread it among the citizens of Rome.

To this end, the North Sea Kingdom brought thousands of smallpox cattle to supply cowpox. Julius II also issued an order to collect cattle from the people for the cultivation and collection of cowpox, so as to supply the needs of the whole Papal States.

In particular, at the beginning of August, a large number of missionaries in the Papal States who had been infected with cowpox went deep into several of the isolated areas of the Papal States to help survivors who had not yet been infected and had an outbreak of smallpox to plant cowpox. During this time, none of the missionaries who had been infected with cowpox contracted smallpox......

Finally, in mid-August, France and Spain, which had been waiting on the sidelines, immediately submitted applications for the introduction of cowpox. After all, these two countries urgently need to control smallpox now!

Of course, after they introduced the smallpox cattle allocated by the Holy See, the first step was not to send them to the epidemic areas, but to the capitals of the two countries first, and to plant cowpox on all the monarchs and nobles. Only then did new smallpox cattle begin to be cultivated and sent to endemic areas for use......

At this time, more than 300,000 people had died from smallpox in the three major epidemic areas of France, Spain and Italy, and the death toll was still increasing.

And after the cowpox was delivered, it immediately triggered a rush and even a scramble. It was the army that got out of the way to get the deal done. Of course, the soldiers also gave priority to cowpox before giving it to civilians......

And Marlin also made a small profit by exporting smallpox cattle to various countries as a source of cowpox. England alone brought in 3,000 smallpox cattle from the North Sea Kingdom. Of course, these cattle were bought by Marin from the Ukrainian steppes of the Crimean Khanate and the Grand Duchy of Lithuania at a cheap price.

……

When the whole of Europe was planting cowpox, Julius II saw that the time was almost up, and announced that he would honor the reward and prepare to confer the throne on Marin.

And Marin, escorted by two thousand cavalry, went south to Rome, preparing to openly accept the coronation of the Pope's father-in-law, Julius II, at the headquarters of the Holy See, in the Lateran Basilica......
