After finally dealing with this beautiful senior who seemed to be his fan, Pang Xuelin returned to the room tiredly.

Looking at the pile of manuscript papers about the BSD conjecture on the desk, Pang Xuelin scratched his head.

Back then, he made a bet with his mentor Tao Zhexuan, and then fell into the big pit of BSD. Although there were also results in the middle, Pang Xuelin knew very well that he was still far away from the final proof of the BSD conjecture, and it could even be called a lifetime series.

The BSD conjecture is a very important conjecture in the field of number theory. It is listed by the Clay Institute in the United States as one of the seven mathematical problems in the millennium, which shows its importance.

From the 1980s to the present, countless genius mathematicians have been working hard to cross the BSD guess this mountain, but so far, they can only climb to the hillside at most.

In 1986, John Coates (Willes' mentor) and Andrew Wiles's type curve for rank=0 proved the BSD conjecture.

In 1987, Benedict Gross and Zagier proved a theorem about the rank=1 curve, which led to the proof of the bsd conjecture of rank=1.

In 1989, Kolyvagin used the euler tool he invented to launch algebrai rank=1 based on the analysis rank=1 proved by gross-zagier.

In 1991, Carl Rubin used Kolivakin's euler tool to simplify the proof of the Iwazawa Master's conjecture. At the same time, he also proved the proof of the Iwazawa Master's conjecture in the case of the virtual quadratic domain, thus giving some results of the BSD conjecture.

In 2013, Zhang Wei, a Chinese mathematician who taught in the Department of Mathematics at the University of Chicago, proved the kolyvagin conjecture under some preconditions.

The following year, Zhang Wei collaborated with skinner to prove the theorem of the inverse proposition of gross-zagier and kolyvagin.

In 2018, Pang Xuelin gave the proof of the polarized Abel cluster andré-oort conjecture.

...

But so far, mathematicians still cannot determine whether r has boundaries, and for sand group iii, it is not known whether its potential is limited.

Sand group is one of the cores of understanding the arithmetic properties of mathematical objects. Only by solving the BSD conjecture can we describe the extent to which the information on the algebraic number domain can be glued to all local domains. This is of great significance, whether it is logistic theory or algebraic geometry.

In the past two years, Pang Xuelin has devoted most of his energy to studying the BSD conjecture and has made good progress.

But in recent months, Pang Xuelin's research has felt like he was reaching a dead end.

He vaguely realized that if he wanted to completely solve the BSD conjecture, with the current thinking in the mathematics community, he might have come to an end.

Unless you create a brand new mathematical tool yourself, or re-prove it from a different perspective.

Otherwise, there will be no progress in a short period of time.

Pang Xuelin sighed. Now is not the time to consider the BSD conjecture, so let’s find a way to solve the inexplicable voice that appears in your mind.

He went to take a shower, washed away the smell of sweat, and then lay on the bed and closed his eyes.

...

At 11:30 p.m., Pang Xuelin was woken up by the set mobile phone alarm clock.

Pang Xuelin got up and washed his face, took out a can of milk from the refrigerator and drank a large cup.

Then, he leaned against the head of the bed, playing with his cell phone while waiting for the arrival of midnight.

There are two messages on WeChat, the first one is the voice sent by my mother.

"Son, do you still remember Yao Bingxia? It was the granddaughter of the old man Yao who lived in the same hospital with your grandfather when he was a child. Didn't their family move to the capital? Today, your father and I went to your uncle Yao's house in the capital. We saw that girl. She was very beautiful, she studied dance and was still studying in Beidian. She had no boyfriend. I want Xiaoxia's mobile phone number. Remember to add it. 135*********."

Pang Xuelin was speechless. Since returning to China, his mother has introduced her to her every few days, as if she was afraid that she would not be able to find a girlfriend.

You should know that you are only 22 years old now, and Xu Sui is only 23 years old, so it’s still early!

However, Pang Xuelin had a little impression of the little girl who kept wiping her nose and following her, just that little girl who was whispering, had she become a big beauty?

Pang Xuelin Cai doesn’t believe it!

In addition to my mother's message, there is also a message that was actually sent by the beautiful senior sister named Qi Xin I just met today.

"Senior brother, my family sent me some dried fruits. I can't finish them alone. I will give you some. I knocked on the door just now, so I put the dried fruits at the door."

Pang Xuelin was slightly stunned and subconsciously clicked on Qi Xin's circle of friends and took a look.

The latest circle of friends is her photo with herself.

Qi Xin stood in front of him, put on a cute scissors hand, and stood behind him, smiling awkwardly.

The caption is: On the first day of returning to school, I met the legendary scholar Professor Pang Xuelin. Hehe, he was more approachable than I thought. Today, thanks to his help to carry my box of more than 100 kilograms to the eighth floor, otherwise I would have been tragic.

Pang Xuelin smiled, got up and came out of the bedroom. When he opened the door, he found a plastic bag hanging on the door handle, which was filled with dried fruits such as packaged raisins, hazelnuts, batanwood, walnuts, pecans and other dried fruits.

Pang Xuelin took out a few and ate them while replying to Qi Xin: "Senior sister, thank you for your dried fruits, they taste very good."

After a while, the phone rang.

"Senior brother, you haven't slept yet so late?"

"I fell asleep before and only woke up saw your message..."

"Haha, I'm going to sleep. Could you be a night owl? Get up in the middle of the night to do research?"

"It's almost the same, I'm usually more inspiring at night."

"Yeah, junior brother, then I won't disturb you. I'll go to bed first and get up early tomorrow, good night~"

"Good night~"

...

Pang Xuelin smiled. After Qi Xin interrupted, his originally a little nervous mood suddenly relieved a lot.

Soon, the clock pointed to zero, and the familiar electronic sound rang out on time in Pang Xuelin's mind.

"Host, is it loaded into the Science Fiction World Adventure System?"

"Host, is it loaded into the Science Fiction World Adventure System?"

"Host, is it loaded into the Science Fiction World Adventure System?"

...

"Confirm loading!"

Pang Xuelin said.

This is the first time he has responded to the electronic sound in his mind in half a month.

As soon as he finished speaking, Pang Xuelin felt a flash in front of him, everything in the room disappeared, and something similar to the game interface appeared in front of him.

Immediately afterwards, the electronic sound in my mind sounded: "The science fiction world adventure system was loaded."

Is this done?

Pang Xuelin was a little confused. I wasn't ready yet!

But soon, Pang Xuelin was attracted by the interface in front of him.

Pang Xuelin had always had moderate myopia before, with his left eye 350 degrees and his right eye 400 degrees. If he didn't wear glasses, he would be blurry in his sight.

But now, he didn't feel blurry at all. The interface in front of him was even clearer than what he saw when he put on his glasses.

This is a long-lost feeling, as if in a moment, the whole world brightened.

Pang Xuelin shook his head left and right, and the interface moved as if he was wearing a set of VR display equipment, but it did not have the dizziness brought by VR glasses.

Obviously, this picture should not pass through the retina, but directly act on its own visual nerves.

Then, Pang Xuelin focused his attention on the picture.

The picture is composed of small squares similar to bronze doors, each small square has a line of characters under it.

"Three Body (Trilogy of the Earth's Past Trilogy), Interstellar Crossing, Base, One-Day Prison, 2001 Space Odyssey, Spherical Lightning, Meet Rama, Heberian, Martian Rescue, Gravity, Bring her eyes, Earth's Cannon, Seven-Level Case, Twenty Thousand Miles Under the Sea..."

These blocks are arranged from top to bottom and cannot be counted at all.

A clear look flashed in Pang Xuelin's eyes. Every square here includes novels, movies, comics, some he has seen, some have not seen, but undoubtedly, these squares represent a world.

He hurriedly asked the system: "System, your name is the Science Fiction World Adventure System. Does it mean that I want to enter these Science Fiction Worlds to take risks?"

"Congratulations to the host for guessing correctly. This system can help the host enter major science fiction planes. As long as the tasks released by the system are completed, they can receive corresponding rewards. These rewards include but not limited to various technological products, technical materials and knowledge beyond the times, such as the BSD conjecture that the host is studying. If the host can complete the tasks released by the system, it may be possible to obtain all the proof processes of the BSD conjecture."

Pang Xuelin frowned slightly. He knew what he was studying in this system. I am afraid that there would be no secret in front of it.

Pang Xuelin asked again: "System, then do you have a way to let me travel to some martial arts fairy planes? Or is it okay to have a plane similar to the Marvel Universe?"

The martial arts fairy plane, not to mention the beautiful heroines and ladies, the practice techniques that can make individuals stronger or even immortal are enough to make people salivate.

The same is true for the Marvel Universe, with various black technologies rampant, even more fantastic than the fantasy world!

"Host, please note that this system is not a low-force system. The martial arts fairy plane you mentioned has too many logical loopholes, the law of cause and effect is not perfect, and it cannot be generated. The same is true for the Marvel Universe, with power imbalance and logic chaotic. Once it is attempted to generate, it is easy to cause the system to collapse. This system only serves the negative eleventh square with the gravitational constant equal to 167 times ten, the vacuum light speed is 29980,000 kilometers per second, the Planck constant is 6626, and the electron power is 1602 times ten, the negative 19th power Coulomb universe, that is, the universe where the host exists. In other words, various technologies that appear in the system world are also possible in the real world."

"In addition, the host does not need to speak, and can communicate with the system directly through brain waves. This system opens the plane once a month. After each time it is turned on, the system will publish corresponding tasks and you can get corresponding rewards after completing the task. The ratio of plane time to the real time is 10,000:1. If the host dies in the plane world, the system will automatically peel off from the host, which may cause unpredictable consequences."

Pang Xuelin felt a stern: "What consequences?"

The system said: "Including but not limited to brain death, cerebral infarction, brain an, etc. Of course, there is also a certain chance of being intact. Host, please note that this month's plane will be opened in ten seconds, and the plane will be opened in a random task, and the host, please be prepared, ten, nine, eight, seven, six, five, four, three, two, one..."

mmmp!
Chapter completed!
