New Shun 1730

After this episode, everything was back on track.

The Children's Army secretly arrested Chen Zhen, and the emperor accepted the Duke of Qi's advice: be more aggressive, the Luocha people are determined to win the negotiations, and more pressure can be exerted.

As a guard, Liu Yu must watch others eat and stand while others sit whenever the emperor appears.

Although the emperor also knows Latin, as the king of a country, he cannot speak foreign languages ​​in front of the delegation in formal occasions. He can speak a few words at the banquet.

In addition, although he knows some, some proper nouns are difficult to understand, and some allusions also require Liu Yu to use examples from the first four histories to make analogies.

The missionary's storytelling level is far inferior to Liu Yu's.

Although Liu Yu's cultural level is just so-so, at least he has read the first four histories, and can basically find corresponding allusions in the Western court, and many of them do not even exceed the scope of the Records of the Grand Historian, which makes the emperor understand very comfortably.

In just over twenty days, Li Gan's satisfaction with Liu Yu, the honor guard, rose sharply, and there was a hint of "he must be present when receiving foreign envoys in the future."

Liu Yu's presence gave the emperor more bargaining chips with those Catholic missionaries.

In the past, Catholic missionaries could use foreign negotiations and mathematical knowledge as inducements or threats, but this situation no longer exists.

Catholic missionaries were certainly worried, and the Count of Savoy of the Russian envoys was also uneasy.

The emperor's questions during several audiences were very sharp. It was obvious that he was very clear and knowledgeable about the political situation in the West, and he knew a lot about the crisis in Russia, and he could often talk about some key points.

The main issues in the negotiations between the two countries were still trade, the Kalmyks of the Junggar tribe and the Torghut tribe, the consulate of the envoys, and going to Moscow to attend the coronation ceremony of Peter II.

These issues need to be finalized one by one. Fortunately, the arrangements on the Dashun side are relatively reasonable and relaxed.

After discussing each key issue, some banquets and programs would be arranged to relax.

By the beginning of May, the Tuerhut tribe and the Junggar tribe were finally exchanged. After not interfering in each other's "internal affairs" and allowing the Tuerhut tribe to go to the snow-capped mountains but not agreeing in principle to send a direct delegation to the capital, the Luosha side also made some concessions on the border issue of the Junggar tribe.

If Dashun is capable, it can drink the water of Lake Balkhash and Yibohai. Russia promised that it would not advance southward in the existing fortress area within 30 years, and the entire border line would be 30 miles ahead of Russia's fortress area in the northwest. And provided a map of the fortress area built by Russia in the northwest to guard against Junggar.

But if Dashun still has not solved the Junggar issue after 30 years, Russia will move south along the existing fortress area for its own "defense needs".

This is a condition that both sides can accept.

Thirty years is just a treaty. If Dashun is still unable to resolve the rebellion in the northwest in thirty years, it proves that Dashun's ability to deploy troops in the northwest is not worth mentioning, and Russia can do whatever it wants; if it can be resolved, then Russia can judge Dashun's ability to deploy troops in the northwest, and naturally will not waste too much troops in the northwest to provoke a powerful enemy.

After the signing of this treaty, the most important issue was finally resolved. Dashun held another banquet as a halftime break in the negotiations.

During the banquet, the emperor made an interesting proposal.

"I heard that there are many talented people in your country's delegation. I also learned a lot of mathematics and physics. I want to come up with a few questions to test you, how about it?"

After Liu Yu translated this sentence, Count Savoy was of course very happy. He thought it was just a little joke and readily agreed.

There are many scholars and students of the Academy of Sciences in this huge delegation.

Some people are semi-professional "spies", such as surveying roads, mountains and rivers, determining the longitude and latitude of the capital, and investigating the defense and military capabilities of the capital's walls.

Savoie didn't take it seriously and agreed.

This little "interlude-like test" was scheduled for the next day. The questions were written in Latin, and they were prepared with hard pens such as quills that they were used to using. They chose an examination room in the Forbidden City.

More than 140 Russians participated in this exam, and they also wanted to take the opportunity to see the scientific level of Dashun.

However, when the questions were handed out, most people were dumbfounded.

There were not many questions.

Get ahead of others.

Every even number not less than 6 can be expressed as the sum of two odd prime numbers, and every odd number not less than 9 can be expressed as the sum of three odd prime numbers. Prove it.

This is the first question.

The original author of this question... these Russians are very familiar with it.

Goldbach is now in Moscow, as a court teacher of Peter II, and also a professor of physiology at the Academy of Sciences... uh.

But Goldbach's conjecture has not been proposed at this time. Of course, this is a problem that cannot be solved at this time.

Half of the Luosha people who took part in the test were deeply attracted by this question and never looked at the following questions.

Instead, they took out paper and pen and tried to solve this question with all their life's knowledge.

Another half of the people found that they had no ideas after reading the first question and decisively chose the next question.

The next few questions were "soft power display and technical intimidation" carefully prepared by Liu Yu.

The second question was very long.

It is known that the length of the meridian loop is taken as one forty millionth of the meridian loop and named "meter".

It is known that the acceleration due to gravity is 9.8 meters per second.

It is known that the speed of a new type of cannon of Dashun is 800 meters per second.

Ignoring air resistance, Dashun's artillery position is XX meters away from the fortress, and the observation platform of the fortress is X meters high. Calculate the elevation angle of the cannon to hit the observation platform.

This is a typical high school entrance examination question in later generations. After removing the air resistance factor, it is not difficult at all.

Liu Yu is sure that there are some people among the Luosha people who can solve the answer.

But the purpose of asking this question is not for the answer, but to tell the Luosha people a few things.

First, Dashun accurately measured the length of the meridian, and after converting the unit, it is almost the same as your measurement, which proves Dashun's level of surveying.

Second, Dashun accurately measured the magnitude of the acceleration due to gravity. Don't worry about how it was measured, it was measured anyway.

Third, the artillery level of Dashun is very good. At least if this question is the exam question for Dashun artillery officers, it tells the Russians from the side that the artillery level of Dashun is second to none in the whole world.

Because, such a question is one of the exercises for French artillery lieutenants in the Napoleonic era. At this time, the artillery level of European countries is still far from that of the Napoleonic era.

The reason why Russian artillery is still excellent and unique among a group of gray animals is that the leading mathematicians in the early 18th century were basically in Russia: Euler, Goldbach, Bernoulli...

The Russians are naturally very sensitive to such questions.

The next few questions are more outrageous than the other.

The third question is the conservation of momentum.

The fourth question is the fastest descent line.

The fifth question is longitude and latitude navigation.

The sixth question is the calculation of the force area of ​​the sail and the angle of sailing against the wind.

The seventh question is the primary differential integral to measure the volume of irregular barrels.

The eighth question is the calculation of triangular trade profit.

The ninth question is to make a regular 17-gon with a ruler and compass.

The tenth question is to calculate the limit of military food consumption and transportation loss.

There are a total of ten questions. Except for the first question, which has no solution, and the ninth question, which is the same as the first question, to lure Euler and others to the capital, the rest are within the scope of solution at this time.

But the people who can completely solve these questions are not in the Luosha Mission.

Perhaps if they are thrown to the Academy of Sciences in St. Petersburg and asked Bernoulli, Euler, Goldbach and others to solve them, there will only be two questions left.

But asking these people to solve them at this time is a bit too much.

Except for the first and ninth questions, which have special purposes, the other eight questions are all to show the soft power of Dashun.

Artillery, navy, navigation, logistics, trade... and Dashun's understanding of triangular trade and knowledge of the world environment.

Liu Yu knew very well that a large part of the people in the mission must be semi-public spies.

If not, he would not have asked such questions, which would be meaningless.

It is precisely because many people come here to spy on intelligence that the questions he asks are not just flirting with the blind.

The whole day of the exam finally ended, and these Luosha people looked at each other, and many people kept shaking their heads.

"How many questions did you answer?"

The person being asked held up two fingers.

"2 and 6, the sail force problem, Academician Bernoulli talked about it. What about you?"

"2 and 5, my father is a naval officer, and I learned about navigation problems when I was a child."

"Do you have any ideas for the first question?"

"No."

"Do Chinese exams only test questions like this? They rely on the 'imperial examination' to select talents. Are all their imperial examination questions like this?"

After saying this doubt, everyone present felt an unspeakable panic.

After a month of brief understanding, they knew that the way Dashun selected civil servants was through an examination called the "imperial examination".

Except for the hereditary titles such as dukes, marquises, and earls, civil servants were not hereditary. This is a terrible system that Russia and even the whole of Europe cannot compare to at this time.

They even knew that among the "Pingzhangshi" of Dashun, the chief ministers of the Privy Council in their eyes, there were several children of commoners, which was unimaginable.

The content of the church school exam was the understanding of the scriptures. They did not know that the imperial examination of Dashun was also the understanding of the scriptures, and they could only guess what the imperial examination of Dashun was testing through this exam.

The ten questions showed the soft power of Dashun in a special way. This soft power, coupled with the imperial examination system and non-hereditary bureaucracy that they had heard of before, made them extremely afraid.

After a day of exams, several middle-aged people from the Academy of Sciences who led the team came to the room of Count Savoy and expressed their judgments with worry.

"Count, I think we should know what kind of neighbor we have to the east. These exam questions show us how powerful they are. Your judgment is correct. Their artillery is very powerful. Although their navy is not strong, they have begun to learn."

"Just like what Peter the Great did, when the shipyard started construction, the future officers had already gone to Europe to study. And when the shipyard was completed, these officers could go directly on board. If Russia can build warships and build powerful artillery, do you think that the richer China will not be able to come up with the money?"
