All accidents in history are inevitable in fate.

……

"Professor Tang, I know this sounds a bit incredible, but in the past half a month, every day at twelve o'clock at noon and midnight, I can hear someone talking in my ear, very clearly!"

"It's supposed to be an auditory hallucination."

Tang Xiuyuan, the chief physician of the Department of Neurology of the Affiliated Hospital of Jiangcheng University, who had gray hair, helped the black-framed glasses on his face, and while using two-finger Zen to record on the electronic medical record, he said: "Xiaopang, you, you put too much pressure on yourself, I will go to the hospital another day to find Lao Liu and tell me that the youngest full professor in our school can't overdraw his health because of work." ”

Pang Xuelin smiled bitterly: "Professor Tang, I mean really, I really heard that sound, a bit like an electronic sound, each time it lasts for one minute, and after a minute, this sound will disappear, and it will appear every twelve hours, very punctual." ”

Tang Xiuyuan laughed: "Xiao Pang, do you know? I once met a patient with particularly severe auditory hallucinations who could hear her mother every day, and even took the initiative to talk to her mother in a coherent and unmistakable manner. But in reality, it has been three years since her mother died. The girl couldn't bear the blow of her mother's death, so she had symptoms of auditory hallucinations. You're too tired in your current situation, listen to my advice, put aside the work at hand, go back and go out with your girlfriend for a few days off, relax and relax, and you'll be fine soon. ”

"I haven't ...... yet"

Pang Xuelin opened his mouth, and was just about to explain, when a familiar electronic sound suddenly sounded in his head.

"Host, is it loaded into the sci-fi world adventure system?"

"Host, is it loaded into the sci-fi world adventure system?"

"Host, is it loaded into the sci-fi world adventure system?"

……

The electronic tone rings every ten seconds and lasts for one minute.

"It's coming, it's coming, Professor Tang, I can hear it talking now."

Pang Xuelin said excitedly.

Tang Xiuyuan subconsciously looked at the time in the lower right corner of the computer, at twelve o'clock at noon on September 5, 2019!

Tang Xiuyuan's expression became solemn: "Did you hear what it said?" ”

"It's just an electronic sound, like it's loaded into some system or something." Pang Xuelin hesitated for a moment and didn't say it directly.

Tang Xiuyuan said: "That's it, I'll give you a list, you do a cranial MRI first, if there are no physiological lesions, I'll prescribe some medicine for you, take it for a while, and see if the symptoms can be reduced." If it doesn't work, go to a psychiatrist. ”

"Good...... All right! ”

Pang Xuelin hesitated for a moment and nodded.

At 3 o'clock in the afternoon, the MRI results showed that everything was normal in the skull and there were no physiological lesions.

Tang Xiuyuan prescribed Pang Xuelin a small amount of thioridazine and asked him to take it for a period of time to see the effect.

MMP, this thing is for schizophrenia, I'm not a neurotic!

Pang Xuelin muttered secretly, and then frowned again.

As a staunch atheist and materialist, Pang Xuelin does not believe in any ghost and god theory, but the voice that appears in his brain at the moment is beyond the scope of Pang Xuelin's cognition.

"Or, when that electronic sound sounds again tonight, choose to agree to try?"

Pang Xuelin's eyes narrowed slightly, and he made a decision in his heart.

……

In the eyes of others, Pang Xuelin has probably always belonged to someone else's child.

He went to elementary school at the age of seven, graduated from elementary school at the age of ten, graduated from junior high school at the age of twelve, won the gold medal at the IMO (International Mathematical Olympiad) at the age of sixteen, and took the college entrance examination in the same year.

After graduating from his bachelor's degree at the age of eighteen, he went to the University of California, Los Angeles, where he studied under Professor Tao Zhexuan, a famous Chinese mathematician and Fields Medal winner.

It takes three years to complete the master's and doctoral studies.

During his master's degree, he has been doing research on analytic number theory and additive combinations, and his representative work during this period is "Estimation of the Sum Product of Rational Functions".

During his Ph.D., he became interested in BSD conjecture.

After graduation, at the recommendation of Tao Zhexuan, Pang Xuelin went to the National Institute of Mathematical Sciences in Berkeley for a year of postdoctoral research, during which he published a "Proof of the André-Oort Conjecture of Polarized Abelian Clusters" in the Annals of Mathematics.

The André-Oort conjecture is closely related to the generalized BSD conjecture, and Pang Xuelin's work has enabled the international mathematical community to take a small step forward in the journey of the BSD conjecture.

It was this top journal paper that made him famous in the international mathematical community, and was praised by the media as a potential player of China's new generation of Fields Medals, and at the same time knocked on the door of the Youth Thousand Talents Program and the full professor of Jiangcheng University.

……

Today is the second month of Pang Xuelin's return to China.

After leaving the hospital, Pang Xuelin drove a second-hand Audi A6 that his father had eliminated and returned directly to the teacher's apartment on the Zijin Campus of Jiangcheng University.

He was specially appointed as a professor and doctoral supervisor of Jiang University.

In addition to the 500,000 yuan settling-in allowance and 1.5 million yuan of scientific research start-up funds, Jiang University also enjoys a half-price discount for a 100-square-meter talent room on the Zijin Campus.

However, Pang Xuelin is not short of money, his father has a carbon fiber material company with assets of more than 500 million, and he bought him a villa on the Binjiang side as a wedding house early.

In addition, his mother also bought several school district houses in his name, and Pang Xuelin had no concept of more money and less money.

Originally, he also thought about whether to buy a house in the neighborhood next to the school to make it easier for him to commute to work.

Later, he thought that the community was a little far away from the school, so he lived in the teacher's apartment arranged for him by the school.

A one-bedroom single apartment, meals can be solved directly in the school cafeteria, which is convenient and fast.

For material needs, Pang Xuelin is not high.

Parking the car in the parking lot near the canteen, Pang Xuelin went to the canteen to have a meal, and then slowly returned to the apartment.

As soon as I came downstairs to the teacher's apartment, I saw a beautiful young lady in a T-shirt and hot pants, dressed in cool clothes, pushing a 28-inch suitcase, standing anxiously at the elevator entrance.

The young lady is not tall, and she is only in her early sixties.

But the skin is like snow, the eyes are bright, and the eyes are bright.

Even if she was in a hurry and her brows were furrowed, it didn't cover up her beauty at all, but added a few different kinds of beauty.

Pang Xuelin couldn't help but take a few more looks, Jiangcheng has been a beautiful woman since ancient times, although he doesn't go out much on weekdays, but such a beautiful young lady, it is the first time he has seen it in the two months since he returned to China.

If the full score is 100 points, the young lady almost reaches more than 95 points.

Seeing Pang Xuelin coming, the young lady's eyes lit up, and she hurriedly stepped forward and said: "This classmate, I am a new teacher from the School of Foreign Languages, I don't know what happened today The elevator in the teacher's apartment is broken, my luggage is too heavy and I can't carry it alone, can you help me?" ”

"Classmates? Do I look so young? ”

Pang Xuelin glanced at the young lady, and said a few words in his heart, but he had no expression on the surface, and said lightly: "What floor?" ”

"Eighth floor!"

"Come with me!"

Pang Xuelin lifted the suitcase, his face changed suddenly, so heavy!

"Come here, the box is too heavy for me to lift it alone, so the two of us will carry it together."

Pang Xuelin turned around and said.

"Huh?!"

Qi Xin was wiping his sweat, and he couldn't help but be stunned when he heard the words.

She knows her charm, but whenever she finds someone to help move things, the average boy is afraid of losing face in front of her, no matter how heavy the thing is, she will grit her teeth and resist.

It's like the boy in front of him, who directly said that he couldn't lift it, and he wanted to help move it by himself.

"Has my charm waned?"

Qi Xin was a little skeptical.

However, she is not the kind of delicate girl, so she reacted quickly and stepped forward and said, "Okay, then let's move together." ”

The two of them climbed upstairs with large boxes one after the other, Pang Xuelin in the back and Qi Xin in front.

"What's in here, why is it so heavy?"

Qi Xin smiled a little embarrassedly and said, "It's all some clothes, books, and cosmetics." ”

"Oh!"

The box was too heavy, and the two of them didn't have the heart to chat, panting all the way, putting it down from time to time to rest, and it wasn't until fifteen minutes later that the box was moved to the door of room 802.

"Classmate, thank you so much, if it weren't for you today, I would be miserable, so let's wait here for a while, I'll get the suitcase in and put it away, and the teacher will invite you to a meal later, thank you!"

Qi Xin said gratefully.

After being a student for so many years, this is Qi Xin's first time as a teacher, and he is also a glorious university teacher.

"No need, I've already eaten just now, and I'm not a student!"

Pang Xuelin said, took out a key from his pocket, shook it at Qi Xin, and then opened the door of room 801 opposite Qi Xin.

Qi Xin was taken aback: "Ah, you live opposite me?" This one...... I'm sorry, you look so young, I thought you were a student, let me introduce myself, I am your new neighbor, Qi Xin, a 19th grade counselor of the Foreign Language College. ”

Qi Xin stroked the sweat-soaked hair on his forehead and stretched out his hand.

Pang Xuelin shook hands with Qi Xin and said with a smile: "Department of Mathematics, Pang Xuelin." ”

Qi Xin was stunned when he heard this, his mouth suddenly opened into an O-shape, his eyes widened, and he said incredulously: "You...... You're that pervert in the math department? …… No, you're the god of math in the department? ”

Realizing that he had lost his words, Qi Xin hurriedly changed his words.

Although Pang Xuelin only stayed in Jiangda for two years, the name of Xueshen has long become a legend of Jiangda.

He completed his undergraduate studies at Jiang University at the age of eighteen, completed his master's studies under Tao Zhexuan at the age of 20, graduated with a doctorate at the age of 21, and published a paper in the top journal "Mathematical Yearbook" at the age of 22.

It's just an open life.

Qi Xin entered school at the age of eighteen, and in his junior year, Pang Xuelin was only a freshman, but in the blink of an eye, four years later, he finally became a counselor at Jiangcheng University, and Pang Xuelin has become a full professor at this top university in China.

The corners of Pang Xuelin's mouth tugged: "If nothing else, it should be!" ”

Qi Xin's face suddenly showed a look of admiration, and said, "Professor Pang, I didn't expect us to be neighbors, just now it was really ...... Thank you so much! Can we take a group photo? I want to show off in the circle of friends, hehe, by the way, can you add your WeChat? ”

Pang Xuelin looked confused.

Are the current beauties so unreserved?
