After going to college, Jian Jian changed the lazy habits he had in a small county town and began to get serious, either in the classroom or in the school library every day.

It's the same as a few roommates in the same dormitory, not particularly good, but it's not bad.

The main reason is that the college entrance examination has finally resumed, everyone is very rare to be able to learn, everyone is studying hard, absorbing knowledge, there is no time and energy to have fun, develop feelings, whether it is classmates or roommates, just get along with each other.

I like this kind of atmosphere where everyone works hard, so I feel very beautiful every day.

It didn't come to an abrupt end until Lin Feifei's suitor sent flowers to the girls' dormitory and caused turmoil on the girls' dormitory.

Jian Jian put down the book in his hand, got up and walked outside the dormitory, looking down from the corridor on the third floor, between which an elegant-looking young man leaned on the side of the bicycle, holding a flower in his hand, standing beautifully in the shade of the tree outside the girls' dormitory.

Well? What's going on? This isn't the male protagonist?

Is it broken?

Jian found that Lin Feifei was still on the fourth floor through his divine sense, so he raised his feet and walked up. She had to ask what was going on.

Under the gaze of a group of girls, Jian Jian entered the 406 dormitory and found Lin Feifei, who was sitting on the bed with a look of shame.

——————

The girls who were originally chattering around Lin Feifei all consciously left when they saw that it was easy to come, and vacated the place next to Lin Feifei for simple sitting.

After writing briefly about the girls, he sat down, "Fei Fei, what's going on with that person below?" ”

Lin Feifei snorted for a moment before replying: "That person is a classmate in my class, and I don't know why he did this, obviously I have clearly rejected him before?" Ahh What if Ah Lei finds out? ”

Simply raised his eyebrows when he heard this.,Oh open.,It turns out that the male protagonist has appeared.。

Seeing that she was so busy during this time, she didn't even know this, and she missed so many opportunities to watch a good show in vain.

However, it stands to reason that she shouldn't know this, and pretended to ask, "Ah Lei?" Who is Ah Lei? Which one is below? ”

Lin Feifei quickly glanced at Jian Jian's expression, and when she saw that Jian Jian was not angry, she replied shyly: "Ah Lei, Ah Lei is also a classmate in our class, and he is now my boyfriend." ”

After speaking, he quickly lowered his head, not daring to look at Jian Jian again.

Jian Jian didn't come here to beat the mandarin ducks this time, since they met again and were together, Jian Jian didn't have anything to say, at most, he completely put his mind at ease, and he didn't have to worry about whether Lin Feifei would learn badly or meet a scumbag.

Some time ago, Lin's father and Lin's mother called and said that they should look at Lin Feifei simply, for fear that Lin Feifei's brain would not be bright and not qualitative, and he would deal with some boys with flawed character.

But now it's easy to worry about it at all, with the luck and family affairs of the male protagonist, it's more than enough to protect a Lin Feifei.

"Since you have a boyfriend, you can tell him if you encounter this kind of thing in the future and let him solve it, otherwise what will your boyfriend do? And bring him to meet me another day. ”

Seeing that Lin Feifei agreed, Jian chatted with her again and went back to his dormitory, as for the boy downstairs, Lin Feifei still told him to leave him, no, he wanted to stand, then let him go, and he would naturally leave when he was tired.

A year has passed in the blink of an eye, and Kyoto University has welcomed a new batch of students, and Jian Jian has also been promoted to a sophomore year.

In fact, because of the strength of his divine sense, he learned everything very quickly and remembered very well, and for this reason, he wrote down all the things that he needed to learn during the year.

Because of the excellent results of the perfect score in the simple subject, Jian Jian won the first place in the major for two consecutive semesters, and also received a special scholarship for two semesters, which brought the wind to the happy walk of Lin's father and mother who were thousands of miles away, and the smile on his face did not dissipate.

Now that the knowledge system of this world has been learned, then it is time to prepare for something famous, after all, the goal of this world is to dedicate oneself to the cause of national scientific research.

If she wants to contribute to the country's scientific research, then her current age is definitely not qualified, and she has to come up with something as a stepping stone.

After all, if you want to study something, you have to spend money, and in addition to the indispensable funds, research equipment is also essential.

It is precisely these things that are most lacking at present.

Although there is money in the simple space, you can get any equipment you want, but can you take it out and use it?

Jian's current identity is a poor student from a rural area, and suddenly if there is no shortage of money and equipment, what do people think?

Don't say that if you enter the research institute to engage in scientific research, it's good not to be arrested and killed.

So, Jian planned to do something that was in line with her math major and to overcome those world problems.

Because mathematics is different from other scientific research, mathematical number theory is that as long as you understand it, you can figure it out by yourself by hiding in any corner with a pen and paper.

Unlike other scientific research, if you don't have the backing of the state and want to do it yourself, you can't fix a few mines at home.

But any student majoring in mathematics, when listening to the professor mention those world problems in class, he can't help but imagine that it would be great if he could solve some world problems.

Now the simple play is also this idea, and in the end, the simple set the goal of one of the world's three major mathematical problems in modern times - the Goldbach conjecture.

It all started in 1742 when Goldbach came up with a conjecture that even he could not prove himself: any integer greater than 2 could be written as the sum of three prime numbers.

Because in 1956, Wang Yuan of Huaguo successively proved "3+4", "3+3", "2+3".

In 1962, Pan Chengdong of China and Barban of the Soviet Union proved "1+5", and Wang Yuan of China proved "1+4".

In 1966, Chen Jingrun of Huaguo proved "1+2".

The Goldbach conjecture has left a strong mark in the history of mathematics in China, that is, when professors talk about these world problems in class, they can't help but talk more.

Although no one has been able to prove this problem for centuries, it is not that difficult for simplicity.

So for the next whole semester, Jian devoted himself to academic research, and in addition to attending classes every day, eating, drinking, and sleeping, it was Goldbach's conjecture.

Whether it was Lin Feifei who saw that she had been bored in the dormitory and came to hang out with her, or the professor valued simplicity and wanted to enter his research room to give him a start, simplicity refused.

Simplicity is the kind of person who is very tough, and he will not easily change what he decides to do.

Now that Jian Jian has decided to overcome this problem, then until he conquers it, Jian Jian will no longer be able to hold anything else in his heart.
