Xueba system prevents me from moving bricks

The Criminal Police Brigade of Donglin City Police Department is doomed to have no sleep tonight, they are still busy until late at night because of what happened in the afternoon during the day.Brigade leader Lu Xiaohu and his colleagues had a midnight snack at 10 o'clock in the evening and went to sleep in the brigade. They won't be going back tonight, and maybe they won't be able to go back tomorrow night. They have to go on a mission, Brigade Leader Lu Xiaohu thought.

The next day, the colleagues got the results overnight, and the deputy captain is now reporting the situation to him.

"The victim, Ma Yong, male, 40 years old, graduated from Donglin University of Science and Technology, is the boss of Haili Technology Co., Ltd., the former boss. His company was recently acquired by Fortune Group because it was on the verge of bankruptcy. The video will be released this afternoon. You can see that they have signed the acquisition and acquisition contract.

Surveillance near Datong Road showed that a woman entered Haili Company at four o'clock before the victim's life, and then we received a report at about five o'clock, which should have been reported by the victim Ma Yong.

Then at three o'clock in the afternoon, a police car stopped in front of his company.The police car stayed there for about 45 minutes.After comparison, we found that the police car belonged to Donghai City, and Li Xianli, the director of Donghai Hot Spring Township, had come to look for him. "

At two o'clock in the afternoon before this, the victim also had contact with Zhang Tian of Futian Group because of the sale of the company.They had discussed the sale a long time ago, and the terms and conditions had already been drawn up, and the only thing left was the signing ceremony of the relevant contract.

"According to the current evidence, it is true that the woman is the most suspected, most likely the murderer. Besides, why did people from Donghai City come to our place?" The head of the high-tech zone's criminal police was curious and made him a little angry.

Did the brothers in Donghai City know the situation in advance to remind the victim?Lu Xiaohu thought.

The next day, he called the Donghai Public Security Bureau to inquire about the situation.

"Comrade, Li Xianli, the director of Hot Spring Township, came to our Donghai City yesterday. Is there any case on our side recently?"

The comrade over there said, "Comrade Donglin, please wait a moment, I will call you to confirm."

A long silence followed.

Lu Xiaohu kept staring at the case file with the microphone, and the death of the victim Ma Yong appeared in front of his eyes, his abdomen was pierced by a sharp weapon, bleeding all over the place...

"Hello, comrade, there is news from our side. Director Li went to Donglin City to investigate the progress of a murder case yesterday, so he went to Donglin City to collect evidence."

"What murder case?"

"I'll give you his contact information, and you can ask him for details."

"Okay, comrade thank you."

Lu Xiaohu contacted Li Xianli by phone and learned about the situation.

Now there are two murder cases, which are more complicated.

Li Ning sees that a summer vacation is about to pass.

Under the guidance of Awen, they now have a comprehensive understanding of the general knowledge of high school, but it is only limited to the surface of the framework. After all, it takes two months to sum up the three-year framework, and the details are definitely impossible. , As for taking the test, there is no way to talk about it.

But the construction of the learning framework is far from being replaced by simple test-taking exercises.

It can be said that it is the most important, but not yet, Li Ning and Li Xiang will understand the meaning of this summer vacation to them in the days to come, Awen thought.

Li Ning was about to end his summer vacation, and he couldn't bear it. The happy time is always short, but he also gained a lot. He read a lot of literature books, history books, popular science books and biographies of great men.

As for philosophy books, he only read one philosophical enlightenment book "Sophie's World", which benefited him a lot.

In the past, Awen always told him that he must experience more society in the future and read more philosophy. If he can only choose one, then forget about philosophy. Without experience and knowledge, it is useless to study philosophy deeply.

In terms of knowledge in high school, Li Ning has the best grasp of history, and he also likes history the most. After investigating him, Awen found that he can now deeply understand the deep-seated reasons behind mastering history.From the Stone Age to the Xia, Shang and Zhou Dynasties, the Spring and Autumn Five Hegemons and the Seven Heroes of the Warring States, the Qin Emperor and Han Wu, the Wei, Jin, Southern and Northern Dynasties, the Tang, Song, Yuan, Ming and Qing Dynasties... Speaking of these, Li Ning has already spoken clearly.Of course, these are only rough divisions. If you want to understand thoroughly, you need to make more refined divisions. The classification will naturally cause controversy.Just like science, one cannot expect a formula to summarize everything in the world, at least human beings have not yet discovered a unified formula.Li Ning is no longer limited to understanding the superficial facts. He is looking for deeper explanations, and even has been able to study some historical theories when he is interested.As for what is the theory of history, simply put, it is the role of history to study itself. Sure enough, everything can be nested, Li Ning thought.This is like the recursion in the computer, calling its own process by itself, and this is also the meaning of metadata: researching the data of the data itself, this is also the meaning of metaphysics.Li Ning suddenly found this process very interesting. He read some English books a few days ago to expand his vocabulary, and learned an English word called metaphysics. The translation is metaphysics, which literally means metaphysics, the study of physics itself.For these, he finds it very interesting, maybe the real world is like this layer of nesting dolls, you set me up, and I set you up.

However, after looking at the history for a long time, he still likes the history of the prosperous Tang Dynasty the most. It seems that he can clearly see the development of this country from the prosperity and decline to the past and present.

In terms of politics, it mainly covers the knowledge of economics, politics, culture and philosophy. Economics mainly introduces daily common sense. Politics introduces the fundamental issues, components, and functions of our political system.In terms of philosophy, after all, the title of the book is a political book, so it has its own standpoint, and it mainly tends to introduce the superiority of Marxist philosophy.

In terms of mathematics, although it is no problem for him to understand a lot of knowledge points taught by Awen, after all, it involves a lot of calculations and practice problems, and he cannot solve problems well. Often Awen gives him a problem, and he has to think about it. For a long time, he gave the answer according to the formula. Indeed, it was difficult for him in such a short time, Awen thought.He still can't apply and practice well, and the knowledge points are only at the stage of understanding how to deduce it. It's not bad to have this grade, Awen thought.Although she verbally says she wants to overwhelm the seedlings, but after rational analysis, her robot understands better than any human beings that human beings are emotional animals after all, and they must rely on motivation, training, motivation, and emotion to stimulate their own growth. What others give them is not after all. What can be obtained by one's own ability is given for nothing.Li Ning has roughly browsed the structure of high school mathematics these days, and thinks that there are too many lacks, such as sets and functions, trigonometric functions, inequalities, sequence, complex numbers, binomial theorem of permutations and combinations, solid geometry, plane analysis, etc. The previous ones are more basic. But he can't do it as a novice just getting started, but he can also know the problem-solving process by fumbling around.

As for the large number of elective courses later, logic terms, conic sections, space vectors and solid geometry, derivatives, number system expansion and complex numbers, and some algorithms and information encryption security related to future computer applications, many of them have reached the superficial level of the university. to an extent.There are also some problems of symmetry and groups, number theory, graph theory, etc. are basically the contents that students majoring in mathematics in colleges will learn. Fortunately, most of them are elective contents, which are not required to be mastered, and the contents are also very shallow. Basically, they are printed in books. Let them have a concept, and save time to go to college. A group of people complain that we have never touched it before.At this time, those old professors will show the textbooks to the students, "Look! I wrote it in the book for you to read, but unfortunately you didn't read it at all! They also said that I didn't teach you. When I leave school, I will say you It’s my student and I feel ashamed.” In any case, mathematics is the most worthwhile and time-consuming subject among all subjects, Li Ning thought, it is indeed difficult, but everything will be fine when it happens.Although it is hard to learn now, it is all worth it.He remembered the biography of Leibniz that he had read this summer vacation. Leibniz also had a headache for mathematics problems, but he firmly believed that his efforts would be rewarded, so he read a lot of mathematicians' works and papers, in order to One day he will become a figure like his idol. The person who is as famous as Newton in mathematics said, "I firmly believe that as long as I work harder, I will become one of them." Thinking of this, Li Ning is even more convinced that he must learn well. Mathematics, don't be discouraged.

In high school physics, Li Ning feels that the knowledge points are not difficult, at least one grade lower than the math problems, but many problems are also very confusing, and the brain can be confused. Sometimes Li Ning feels that this subject should be cultivated Based on interest, not for practice, he thought.Those wonderful laws of physics are the greatest treasures of the discipline of physics.He worked on the subject of mechanical analysis and ball collision for several days in a row, and he felt like vomiting when he saw the force analysis. Fortunately, it was not difficult. He was very interested in the knowledge of gravity, aerospace and space. He used to read a science fiction book. In the novel, the issue of the speed of the fourth universe was crazily introduced.The charm of physics lies in the elegance and neatness of the theory, and in the stage of practical technical application of the theory and experimental verification of the theory. This is an idea that will have a huge impact on real life and actually change the way of life of human beings. Li Ning thinks that if in the future Being an aerospace systems designer is also good.The most important and difficult points in physics should be the force analysis, motion analysis, and energy issues of charged particles in the electromagnetic field. Li Ning thinks that he can feel that it is a black hole vortex, because he is also a little ignorant, and he is not yet familiar with it. , There are too many knowledge points in various subjects and knowledge, and he is a little bit out of control.Well, summer is almost over.
