It can only be said that there is indeed a reason why Yu Yanjiang became the deputy chief engineer of the moon landing program.

Not only is he stingy, but he also has a resolute and resolute temper.

The next day, a special teacher was hired to start a class with Qiao Yu, and the content of the class was naturally about confidentiality.

The teacher's surname was Wen, and his unusual temperament was highlighted when he met Qiao Yu. He was indeed the teacher who taught him confidential knowledge. His name is unknown, and his unit is unknown...

When Qiao Yu asked about it for the first time, Teacher Wen said with a smile: "I am a teacher who teaches you such unpopular things, why do you ask so clearly? I can't help you with academic research.

.

You don’t have to remember me in the future. As long as you can do what I teach you, Teacher Wen, I will be very happy! I’m not trying to scare you. About two-thirds of the people I taught went to use sewing machines.

Already."

This sentence surprised Qiao Yu. It seems that not so many accountants use sewing machines, right?

"No, Teacher Wen, then this is because you did not teach well, or because you are teaching a quick introduction to sewing machines."

Teacher Wen was not angry at all, but laughed.

"Haha, there is no such thing as not being taught well. Before they go in, I will participate in the interrogation process. Without doing anything else, I will first list the things they have committed, and then ask them if they still remember what month and day I was.

In which class did I tell them about it?

Guess what? As soon as I use this memory recovery number, they can remember a lot of things right away. The effect is pretty good, but by then it’s too late to regret it. So I suggest you study hard. Although it may not be used too much this time.

many.

But with your age and ability, you will still be in your thirties in another ten years or twenty years. The things you will have access to at that time will be different. The things I am learning now will definitely be useful to you.

It’s a lifelong benefit.”

Qiao Yu thought for a while and said, "Well, you can teach confidentiality and participate in the interrogation of leakers. Teacher Wen, I think I can probably guess what department you work in."

"Okay, I'll just tell you that I guessed wrong! Hey... to be honest, this is my first time taking a class with a guy as young as you, and it does feel quite strange." Teacher Wen shook his head and said.

Qiao Yu asked curiously: "Oh, then you must have a senior teacher title, right? And you are the kind of senior teacher who doesn't often tell the truth, otherwise you wouldn't deliberately emphasize it like this when you tell the truth."

"Okay, let's not waste time and start class. Today I won't talk to you about those cold regulations. Let's start with a few cases and talk about the gap between what is and should be about confidentiality.

By the way, one more thing, in the past twenty days, we have had two classes every day, one in the morning and one in the afternoon. Before all classes are completed, I will temporarily stay in Room 302, Building 8, Rongyuan Hotel.

If you have any questions, you can ask me at any time. Of course, you can also ask on the phone. You must listen carefully and don’t miss the lecture! After all, we also have to take exams, and the exam results are very important."

…

In this way, the first class ended with many cases. It also gave Qiao Yu a clearer understanding of confidentiality.

It turns out that criminal law is quite different. For example, criminal law has a principle of modesty, which means that when investigating criminal liability, the intervention of state power should be limited as much as possible.

Therefore, it is very important for various judicial agencies to try their best to investigate the subjective intention of the suspect, that is, the criminal motive for many criminal facts.

If the crime is not subjective and intentional, basically the sentencing will not be too high. But confidentiality is different. There is no need to consider the motive at all, only the result.

The severity of sentencing or punishment is related to the level and scope of the secrets leaked. Even if there is no subjective intention, or even no benefits are received, it should be so...

Of course, it could also be the first class. In order to attract Qiao Yu's attention to this course, the teacher Wen told a few special cases specifically to scare people.

However, after studying for a few days, Qiao Yu still felt a little different.

Before, he only thought that the confidentiality training mentioned by Yu Yanjiang was nothing more than casual talk about the contract and emphasizing the importance of confidentiality.

He never expected that this course would actually involve quite a lot of things. It was far more than what he imagined, and also included various technical knowledge.

For example, information security and network security, information confidentiality principles and management, various encryption technologies, including but not limited to different levels of security protocols and standards.

It even includes military and intelligence, legal and ethical analysis, etc. The most exaggerated thing is that all these courses are taught by Teacher Wen alone.

He arranges classes just like high school. Although he is the only teacher, different courses are arranged for each class, combined with various cases and citations. It sounds very interesting, so Qiao Yu can't help but indulge in it...

Well, it can only be said that there are talented people in all walks of life. There is no doubt that this teacher Wen is definitely a leader in the field of confidentiality, at least in Qiao Yu's opinion.

After all, he feels that he still has a basic ability to distinguish. For example, there is a set of objective standards for judging whether a teacher's lecture is good or not.

Qiao Yu also began to believe that this teacher Wen probably really taught many big guys, and it was no joke to get two-thirds of them in. After all, he really told many incredible cases.

Qiao Yu even began to lament that he really had so little knowledge! He even felt like a frog in a well. Really weird things could happen in the world.

No matter how awesome the screenwriter is, no idea can happen in this real world.

For example, more than ten or twenty years ago, an ordinary person somewhere who had just been laid off happened to pass by a company that was relocating, so he walked directly in with a box containing personal belongings, and took away three very inconspicuous mechanical hard drives.

Then this person took it to a second-hand processing place to sell it, and found that the data could not be read normally. Then he treated it as scrap and sold it directly to a second-hand merchant at a price of ten yuan per piece.

The business owner had some knowledge and knew that the hard drive was encrypted, so he put it on a professional forum for help.

Unexpectedly, there was a master on the forum who helped him find a way to decrypt the hard drive. Then he found that there were encrypted files in the hard drive. After trying to read it, it turned out to be confidential research information on a certain control system that was extremely advanced at the time...

…

After monitoring the data, the investigation work was immediately started. From the top management unit, to the company responsible for scientific research, to thieves, to merchants who recycle second-hand computers, and to the masters on the forum, everyone was arrested...

A small case involving a total amount of 30 yuan sent more than 30 people to use sewing machines. The company involved was not only fined, but also had its qualifications revoked. The loss is conservatively estimated to be several hundred million.

According to Teacher Wen, after the accident, everyone inside felt that it was so unfair, especially those who were sentenced to twenty years. They all felt that they were contemporary Dou E.

But after the review, people were speechless. After all, if it were handled according to normal standards, this kind of thing would never happen.

As long as the second-hand merchants and the masters on the forum have a little respect, they will not cause trouble like this.

So the instigator of the whole thing - the guy who impulsively ran into another company's company and took away three hard drives due to layoffs - received the lightest sentence in this case, and even so it was only three years.

Coincidentally, this case took almost three years from the initial investigation to the final trial, so the guy was released a few days after the sentencing...

There are many similar cases. This is not the most bizarre. In short, Qiao Yu and Teacher Wen are still very happy getting along with each other these days.

Qiao Yu quite liked the feeling of adding more strange knowledge every day. The most important thing was that the cases introduced by Teacher Wen gave him a deeper understanding of how the world works.

At least he can't do whatever he wants. There are too many surveillance systems. The good news is that at this stage, Chief Engineer Yu and his mentor are protecting him, so he won't be exposed to the kind of people who can really send him in.

Confidential or even top secret data.

But coincidentally, both parties thought it would be a good thing for him to be exposed to this kind of knowledge and to be awed by it.

…

In Teacher Wen's course, one month has passed in 2026, and the winter vacation has ushered in.

Although for Qiao Yu, life now is no different from life before holidays.

No, he is even busier than he was in the previous semester. Because he really has to go to class every day now. There are two classes a day, and one class lasts two hours.

On the afternoon of February 2nd, after finishing the two-hour lecture as usual, Teacher Wen said: "I have good news for you. You can have a day off tomorrow."

This surprised Qiao Yu. In fact, he didn't feel very tired in class every day.

Although Chief Engineer Yu has sent over some data, he is already on the right track. He has already contacted the Computing Institute.

He provides functions for processing data, and the people connected there are responsible for processing them in the way he provides.

At present, as agreed before, it is all non-sensitive data that can be found from public channels.

For example, the orbital parameters of the moon and the earth, the gravity of celestial bodies, tidal forces, gravity environment, communication positioning, etc.

The other party hopes to analyze these data and provide something to verify many plans.

For example, the optimal launch window for the lunar transfer orbit, the perturbation analysis of the Earth-Moon and Sun gravitational orbits, the optimal fuel allocation for multiple orbit corrections, and even the selection of landing sites, etc...

As we all know, both the earth and the moon are dynamic celestial bodies, and their relative positions are constantly changing.

Therefore, if you want to carry people to the moon, you need precise orbital insertion and transfer windows, instead of just sending people out on a ship and landing on the moon like in science fiction movies.

Of course, the moon landing project must have its own model for these things. Now let Qiao Yu process the data, most likely for comparison purposes.

Anyway, the work at this stage is actually free. Before finishing the confidentiality class, it was basically voluntary work. So Qiao Yu didn't feel any pressure at all.

After finishing Teacher Wen's class every day, he even had time to read a few articles about affine Weyl groups.

There was nothing he could do. Director Tian was urging him every day to take other people's affairs into consideration. Lao Xue's work was already going on, so Qiao Yu felt that there was no need to rush him too much.

So I had to do some preparatory work by myself. During this period, he also added some knowledge about algebraic groups, Lie algebra representation and quantum field theory.

At this time, I suddenly heard that he was going to be given a day off. The first thing I felt was that I was not used to it.

"Isn't it right? Teacher Wen, what are you doing on vacation? It's only four hours a day. You teach me alone and I'm not tired, and I'm not tired when I study, so what's the point of taking a vacation?"

Besides, the Chinese New Year is about half a month away, don’t you want to finish teaching me before the end of the year and then live a good New Year in peace and contentment? Why are we wasting that time!"

Teacher Wen said with a smile: "Actually, I think so too. But yesterday the master of your faction specifically told me that your birthday is tomorrow and he asked me to give you a day off. This old man's opinion is that we, as juniors, still

To be respected."

After hearing this, Qiao Yu was stunned. This period of time was so fulfilling that he even forgot his birthday.

Yes, tomorrow is February 3rd, and he is one year older. Unexpectedly, the old man still remembers...

"Hey... Actually, I often say that birthdays are nothing easy to celebrate. This thing is like reminding you that you are one year older and one year closer to leaving this world."

Qiao Yu sighed, and then found that something was wrong with Teacher Wen's expression, so he quickly added: "Well, I didn't mention you, Teacher Wen, you look quite young, you are in your forties at most. Still.

There is a lot of youth to squander..."

"Okay, you don't need to talk nonsense. I am already forty-eight this year! It is impossible to squander my youth. But you can go and squander it tomorrow, and that's it, let's go."
To be continued...
