Professor Li, do you remember me? I'm Sun Chongde, and we met at the academic forum in Princeton......

"Hmm...... I seem to have the impression that you're also studying number theory, right?"

"Yes, yes, like you, I studied the Riemann conjecture, I didn't expect to see you here, can I talk?"

"Of course, let's go for a walk."

Shen Fanyin always knew that her grandmother was a king.

She just didn't expect that after so many years, grandma was still the king.

Shen Fanyin walked behind her grandmother, listening to the professional terms that she didn't understand at all, and felt that her IQ had been crushed.

Grandma may not remember who Sun Chongde is, but Shen Fanyin recognizes him. Dean of the Faculty of Mathematics at Anseong National University, whom she had met at graduation ceremonies. From the analysis of the worship of his classmates in the academy, there is no doubt that this is also a king.

The tricks of the king and the king, although I can't understand it, the gold content is bound to be very high.

She really wants to share her knowledge with Su Mu.

So she took out her mobile phone, recorded a sixty-second WeChat voice, and sent it to Su Mu.

Three minutes later, Su Mu's cordial greeting arrived as scheduled.

Shen Fanyin didn't listen at all, and directly stuffed the phone into his bag.

She just wants to be a porter of knowledge, and she doesn't need to thank her.

After walking around Qinghu for a while, Grandma's footsteps stopped.

"I'm sorry, I want to go to the bathroom." Grandma's smile was gentle, it was Shen Fanyin's long-lost peaceful and pure smile.

She had only seen this kind of smile five years ago, and she had never seen an old man smile like this since she hit her grandmother in a mental hospital.

Aunt Zhang accompanied her grandmother to the bathroom, and Sun Chongde walked to Shen Fanyin.

"Hello Dean Sun." Shen Fanyin greeted him obediently.

"Well, hello." Sun Chongde nodded his head, "I remember you, Lao Zeng's little apprentice."

Shen Fanyin couldn't help but breathe a sigh of relief.

She was afraid that he would ask herself why she didn't study math.

Sun Chongde looked at Shen Fanyin and smiled kindly: "Just now I asked Professor Li to invite her to give lectures and continue her research in the college, I think she seems to be a little hesitant, can you ask why?"

Shen Fanyin's smile froze at the corner of his lips.

Before the accident, my grandmother was a doctoral supervisor at Ontario, but after that incident, she never went to the podium again.

Shen Fanyin didn't know what reason Ms. Shen used to resign for her grandmother, but her grandmother's current situation, I am afraid that if she goes to give a lecture......

"To tell you the truth, Professor Li has always been a leader in number theory research, and the research results she left behind five years ago have only recently been thoroughly understood, and it is extremely difficult to continue."

Sun Chongde's posture was very low, and there was a passion for mathematics in his eyes that Shen Fanyin did not understand: "The study of number theory is the most talented, and to be honest, I really hope that Professor Li can return to Ontario, we need her."

His eyes were too sincere, coupled with his trust in his alma mater, Shen Fanyin sighed lightly and told his grandmother's illness truthfully.

Finally, she added, "I didn't tell my grandmother about Alzheimer's disease, I hope you keep it a secret and don't put too much pressure on her psyche."

Sun Chongde had a serious expression and nodded very seriously: "Of course, I won't tell anyone anything about Professor Li's illness."

After a moment of silence, he added, "But I still hope that Professor Li can go back to school, even if he can't give lectures, it's good to take two doctoral students and continue his research. Truth be told, which of us old guys doesn't have any sickness? Professor Mao of the Institute of Physics has to be pushed by his students in wheelchairs when he walks."

Sun Chongde straightened his clothes and said seriously to Shen Fanyin, "I hope you can think about it carefully."

Shen Fanyin pursed her lips and nodded, "Okay, I will discuss this issue with grandma seriously, I fully respect grandma's wishes."

She unconsciously looked in the direction of the bathroom.

Grandma just came out of it, the road was narrow, and Aunt Zhang was behind to protect her. Her steps are actually very steady, not shaking, and very tough.

"Good, good." Sun Chongde smiled and nodded, and then asked, "By the way, why didn't you study mathematics?"

Shen Fanyin: "......"

Soul torture may be late, but it will never be absent.

Sun Chongde seemed to have something to do, so before leaving, he asked Shen Fanyin to write down his phone number and say goodbye to them.

Shen Fanyin had been waiting for her grandmother to come and talk to her about going to Anda, but her old man acted like nothing had happened, and continued to drink tea and read books when she got home.

It's just that Shen Fanyin clearly saw that the book she was holding was no longer mathematics for postgraduate entrance examinations, but "Fundamentals of Number Theory".

Shen Fanyin looked at her grandmother from afar, and a question lingered in her mind-

If it hadn't been for that, Grandma might have figured out what to conjecture, right?

"So, that's why you suddenly hit me with a high number while I was counting the money?"

"Mu Mu, please prioritize clearly, I'm talking to you about grandma, don't you have personal emotions, okay?"

Su Mu glared at her, and was silent for a moment before saying, "Actually, you have made your own decisions, haven't you?"

"Huh?" Shen Fanyin frowned slightly, looking at her with doubts in her eyes.

Su Mu said, "You have been emphasizing that grandma's condition has been curbed by giving me tutoring, in fact, you want grandma to go back, right?"

Shen Fanyin's brows furrowed even tighter: "But grandma's body ......."

She had too many concerns to make the right decision.

"Grandma loves math as much as she loves you," Su Mu leaned on the crack of the door and glanced at her grandmother, who was reading seriously, and whispered, "Maybe going to school can really make grandma happier?"

Shen Fanyin leaned against the wall and was silent.

There are so many people in the school, what should I do if my grandmother is bumped into or lost?

Shen Fanyin had a headache and was so entangled.

Fortunately, there is someone back at home who can make up ideas.

"Zeheng is back......

Grandma heard the sound of the door and just took off her reading glasses when she saw a dark shadow flashing.

Shen Fanyin ran to Jing Zeheng's side, dragged his arm to his studio, and said, "Grandma, you are busy first, I have something to do with my brother!"

Grandma: "......?"

Jing Zeheng was dragged into the studio by Shen Fanyin with extra cooperation, and when she closed the door, he asked, "What's wrong?"

Shen Fanyin described what happened for the second time, and then looked at him expectantly: "Brother, you say, should I persuade my grandmother to go to school?"

It's about grandma, Jing Zeheng thought seriously for a while, and nodded, "Yes."

He added: "The old man is obviously very fond of mathematics, and she currently disagrees only because of her own illness. Moreover, if even the graduate school entrance examination in mathematics can curb the rate of deterioration of her condition, then more advanced research must be more beneficial to her mood and recovery."

Shen Fanyin's eyes were entangled: "But ......"

"I can let Aunt Zhang accompany Grandma to school." Jing Zeheng patted her on the head, "It's just a matter of putting an extra chair in the lab, they will agree."

Shen Fanyin's worry was blocked from his lips.

Such a simple solution, she didn't expect.

Concern is chaos, obviously concern is chaos.

Su Mu: "Oh, Yinyin, you didn't even think of this? What about your IQ? Why don't you teach you high math and make up for it?"
