Then the next itinerary is very simple, Xavier plans to go to the kingdom of Vasiliki in the south immediately after solving the assassin incident, learn from Viscount Wallace, and then return to the capital to participate in the knights' conference in July.

However, he had considered that if they couldn't find the assassin, he would have to leave by the end of February at the latest, leaving the mess to Captain Andrew, after all, he didn't have much time, and the task of three skill points was not worth his time to deal with.

Immediately, he went to the window again, this time it was the same pigeon, and unlike the last time, this time the letter was too far away and required a certain fee, so Xavier almost wanted to run his own errands.

It was only when he saw the pitiful look on the pigeons' face and realized that it was not expensive—only five euros, and Xavier paid for it, which was not as expensive as a meal in the inner city, and as the saying goes, time is money, and it is worth saving time.

Thinking of this, he threw a coin into the coin machine that appeared on the table, causing the pigeon in front of him to suddenly show a happy expression, and quickly let out a cooing sound, biting the letter Xavier handed him, and flying to the central police station in the distance.

So while waiting for Captain Andrew's investigation, Xavier still has a lot to do, such as training the cheap apprentice Nord to help him improve his strength, but considering that people are still taking the swordsman exam, Xavier decided to take a look in the library first to understand the background science of this world.

Although he only has a high school background in mathematics and science, and he doesn't understand the theory of relativity, he can't benefit mankind like a certain Professor Lu and a headshot maniac, but at least in his knowledge, there should be some beyond this world.

Immediately, he hurriedly read a lot of books, selectively learned about the background science of this world, and asked the young ladies in the neighborhood to get their recommended books.

Then, after a few hours of reading, he wondered if there was something wrong with his IQ.

Because the explanation of magic is completely a kind of heavenly book! He can't understand it at all!

With his limited mathematical knowledge, those should be a bunch of mathematical models, depicting magical behaviors through various functions, but his mathematical ability in his previous life was obviously not enough for him to fully understand, so he had to give up in the end.

But the mathematics is more interesting, such as calculus or something, which has already appeared, and like in the previous life, it was made as a tool when studying mechanics, after all, calculus was originally a tool for Newton to make mechanics.

Moreover, the second math crisis does not seem to have erupted at this point in time, which means that the definition of infinitesimal is still unclear, but Xavier does not quite remember how to express it, and can only blame him for not studying well in his previous life - or that he was not taught at all in high school.

Also, what Fermat's theorem, Goldbach's conjecture and Riemann's conjecture have also appeared in this world, but Xavier obviously doesn't have the ability to prove them, and the first one is still regarded by him as a difficult question, although he does know that there is an answer, but he also has to know

All in all, when it comes to mathematics, Xavier can pretend to be a bit of a fool if the world is still in a state of ignorance, but as an ordinary person who only knows a little about calculus, it is still a little difficult for him to help the current math tower to a higher level.

As for the three major sciences?

Biology is obviously the most ahead of the times, after all, what DNA and the like, people in this era are impossible to discover, but Xavier can't get an electron microscope, it can only be developed based on quantum mechanics, Xavier doesn't have that ability.

As for chemistry, the concept of the periodic table has long been proposed, Xavier knows the most about what elements are coming up, but there is one thing he remembers very clearly, that is, the Harber method, the method of producing ammonia, that is, NH3, the specific steps, and the pressure and temperature, he remembers it clearly, which is more feasible so far, and where he can really contribute.

In addition to biochemistry, the rest is physics, and he has seen physics science programs since he was a child, and he should also have some scientific knowledge that transcends the background of the times.

Don't say it, there really is!

According to Xavier's high school physics knowledge, the physics of this world has only reached the level of the nineteenth century, that is to say, the two foundations of modern physics, relativity and quantum mechanics, have not been studied at all, and the current world is still studying the pile of electromagnetic mechanics and classical mechanics.

For example, the electric bell in front of Count Josephine just now uses the effect of electromagnetic induction, and there should be similar mechanical means for elevators and the like, but it is just mixed with magic.

So, with Xavier's current level, is there a way to raise the physical level of this world?

Maybe there is, maybe not, the reason is still very simple, Xavier is not good at learning.

There is nothing he can do, after all, he studied liberal arts in college, and the knowledge he has is only high school physics.

The perception of the theory of relativity is that time is relative, and there is the famous formula e=c2, but it is estimated that if he is asked to put it up directly, the magicians will only think that it is a civil science who is talking nonsense.

On the contrary, it is quantum mechanics, he will brag about it, after all, everything is indecisive, quantum mechanics, for the relevant cognition, he is still relatively sufficient.

For example, what electron double-slit experiments, as well as Bohr's model, these should have been understood by ordinary people in the previous life, and any high school student could blow a lot of them to you, Xavier is no exception, but he lacks experience in writing essays and doesn't know how to express them in detail.

The most important thing is that there is still an entry point, how to transition from the pile of physics knowledge he doesn't know to the place where he knows the skin, which makes him start to think and find the key to the problem.

The photoelectric effect, as well as blackbody radiation!

These two places are the beginning of quantum mechanics, and even if he only scratches the surface of his knowledge of specific knowledge, he will still try to express it.

Otherwise, what contribution will he have to this world when he has crossed over?

Thinking about this, he started to work in the era of the college entrance examination, and once again read a lot of books, but this time the scope was much more concentrated, and he wanted to try to come up with an article that tried to explain the important difficulties of these classical physics.

If not, he would try to write about how to make NH3 in large quantities, which would be a contribution.

As for what happens after that? That's not something he's going to worry about.
