I have to say that after Duan Xu had two strange dreams, his whole body actually changed a lot.

Humans are quite strange animals. After experiencing certain things, their temperament will be different as their personality changes in their bones.

If Duan Xu used to be a hard-working and diligent boy, then Duan Xu now gives Sun Shuxia the feeling that she has grown into a man who can take care of her family with a high profile.

Of course, Duan Xu is not a dwarf in the giant action of language. He is just waiting for an opportunity to rise.

He knew very well that the difficulties and dangers he had to face, and he knew deeply that there was nothing else he could rely on except the vast amount of knowledge from the earth.

As for the memory of the future, Duan Xu didn't care much about it.

The reason is very simple. He read a book that tells the story of the butterfly effect. With the appearance of his butterfly, whether it is his adoptive mother or sister, their future will undergo some changes, so some memories about Shui Lanxing are of little use.

Of course, it is not that that memory is of no use at all, at least it is helpful in major events.

Just like now, Duan Xu is very sure to convince Sun Shuxia.

"Mom, I think this can be tried." Duan Xu looked at Sun Shuxia and said slowly: "The situation in our family will not be too bad. It's amazing that I won't take the college entrance examination. I will work with you and let Xiaoyu study. When she makes a fortune in the future, I will buy me a house and car."

After a pause, he smiled and said, "If the business is really good, then you can also relax. Xiaoyu and I can continue to study, right?"

Convincing others is a process. In other words, Duan Xu captured Sun Shuxia's psychology.

It is pitiful that parents in the world have no mother who will give up the opportunity to let their children enjoy a better life.

Sun Shuxia nodded and said, "Let's do this, I'll go and have a look today. If it's OK, I'll give it a try."

After all, she was a little worried. After all, she had never done a small business before, so naturally she didn't understand the twists and turns in it.

Duan Xu did not stop her. Her adoptive mother was an adult and had her own judgment and ideas.

Because it is a weekend, Duan Xu will not attend classes. Although it is in the third year of high school, there is a big difference between Shui Lanxing and Earth. The education department strictly prohibits tutoring, even the third year of high school students in the third year of high school, junior high school. Once discovered, all from the principal to the teacher will be expelled. Therefore, no one dares to take such a risk to make up for classes. Everyone goes to school for eight in the morning and five in the evening study will not exceed seven o'clock.

It is precisely because of this that Duan Xu has enough time to do odd jobs to supplement his family income.

Sun Shuxia went out to DH District to continue her "inspection". Liu Shiyu was reviewing her homework, while Duan Xu returned to her room, took out a notebook, and started writing on it.

People in the world only know that gold is expensive, and don’t ask God to buy young people.

The best life for a person to live is his youth, because at this time, life is the time to choose the direction. As long as you choose the right path and continue to move on unswervingly, you will eventually achieve something.

Duan Xu has read many novels. Once the protagonist in it is reborn in his youth, he will always be able to get shocking results and quickly become a top student, as if all the memories in his mind are cheated.

But novels are novels after all, with full ideals, and reality naturally feels quite skinny.

Looking at the mathematics learning questions in front of him, Duan Xu looked strange because he found that although he was well-read and well-known in astronomy and geography, he really didn't know the analytical geometry problem in front of him.

Mathematics is a rational analysis. To put it bluntly, you need to remember a lot of formulas and do a lot of exercises to achieve the point where practice makes perfect and thorough.

So no matter how many books Duan Xu has read, as time goes by, he has basically forgotten all the mathematical formulas. The only thing he can do now is to pick up the book honestly and pick up the knowledge he used to.

Fortunately, I live a frugal life and have used books. When I encounter something I don’t understand, Duan Xu finds out the textbook and reviews it according to the answers and formulas above.

Two full hours passed, and when Duan Xu raised his head again, he felt his eyes swelling a little.

The difficulty of high school mathematics compared to junior high school mathematics lies in the integration and diversity of knowledge points. Often, a big question involves several knowledge points.

In the past, Duan Xu didn't have to work so hard to solve these problems. However, although he is eighteen years old now, his mind is filled with memories that do not belong to this era. This makes him have to do his best to recall certain formulas.

Duan Xu can swear to the sky, he thinks the difficulty of high school mathematics is comparable to that of marathon cross-country.

Fortunately, there is still half a year before the college entrance examination. Duan Xu knew that he still had enough time to prepare to integrate the knowledge in his mind and allow himself to successfully pass the single-plank bridge of the college entrance examination.

Putting down the math textbook, Duan Xu took a look at the remaining papers. He is now extremely glad that he chose liberal arts. If it was science, the lot of exercises that needed to be calculated in science could make him dizzy. In addition to geography, the rest of liberal arts is memorizing questions. At least he doesn't need to spend too much time catching up with his classmates' progress.

As for the two courses of Chinese and English, Duan Xu didn't think this would be a problem at all. He has read so many books and his background, no matter how bad the Chinese grades are, he can guarantee more than 100 points. In English, one of Duan Xu's biggest gains on earth was that he used his time as a librarian to learn seven foreign languages.

No matter which language it is, the mastery of vocabulary actually determines the proficiency of a language.

Duan Xu doesn’t think that the current high school English test questions can stump him.

It has been several days since I woke up from the "dream". Through reading newspapers and news, and inquiring from the side, Duan Xu now has a vague guess about the relationship between the Shui Lan Star and the Earth where he lives.

The relationship between these two planets should be similar to the parallel universe proposed by some theoretical physicists on Earth.

The so-called parallel universe refers to other universes separated from a certain universe and exist parallel to the original universe. In these universes, there are also universes born on the same conditions as our universe, and there may be planets that are the same as the planets inhabited by humans, or people with the same history, or people who are exactly the same as humans. At the same time, in these different universes, the development of things will have different results: species that have already become extinct in our universe may be constantly evolving and endlessly reborn in another universe.

Some scholars used this metaphor when describing parallel universes. They may be in the same space system, but the time system is different, just like two trains galloping on the same railway line; they may be in the same time system, but the space system is different, just like cars driving in the two upper and lower channels of the overpass at the same time.

Simply put, two worlds that exist simultaneously have similarities but subtle differences.

In Duan Xu's opinion, his current situation is like two straight lines, occasionally there is a crossing place, and then he moves forward without looking back.
