Genius club

Ji Lin didn't pick up the list.

Instead, he turned the pencil over in his hand, picked up the April issue of Mathematics Monthly next to him, turned to the Sudoku page, and continued to fill in...

"Actually, I've always thought your words were strange."

He quickly filled in the numbers and said softly:

"Obviously everything affects the future, why do you always talk about history when you open your mouth?"

"It's not important, it's just a statement."

The old man walked to the floor-to-ceiling window and looked at the moon outside the window, his eyes a little red:

"Xu Yun... is my favorite student in my life."

"I can tell."

Ji Lin didn't look up:

"You betrothed all your daughters to him. You were afraid that he would not agree, so you lied and claimed that she was your niece. But it is not a lie, because my sister doesn't know her life experience, nor does she know that she is The product of a fling in your youth.”

The old man widened his eyes and turned around:

"How do you know? I don't know anyone about this..."

"Is it hard to see?"

Ji Lin threw aside the April issue of Mathematics Monthly. It seemed that the questions in this issue were a bit difficult, and he obviously spent more time:

"Since I was adopted by you, my sister has raised me single-handedly. Although I call her sister, she actually plays a more mother-like role to me."

"I don't think it's that hard to tell that she is an illegitimate daughter...but I have to say that you hid it very well. Even my sister didn't find out."

"Did you tell her?" The old man stared at Ji Lin closely.

"No, why did I say this?"

Ji Lin disagreed, picked up the May issue of "Mathematics Monthly" on the floor, turned to the Sudoku page, and continued to solve the problem:

"At that time, my sister complained to me, saying that you insisted on bringing her and Xu Yun together. She actually didn't like nerds like Xu Yun... These were her exact words."

"But later after getting along, she thought Xu Yun was quite good, and the two of them got married. You organized the wedding, which really took a lot of effort."

The old man was silent for a long time.

Sighed:

"So... Xu Yun's death makes me feel more heartbroken than anyone else. I must find the murderer who killed Xu Yun!"

"When your sister gave birth to Xu Yiyi, she died of amniotic fluid embolism... Since then, Xu Yun has wanted to study hibernation cabins as if he was possessed by a maniac. I tried my best to persuade him, but I couldn't persuade him to come back."

"So in the last moment of anger, I expelled him from the school and parted ways, thinking that in a few years he would give up and come back to me... But it was all because of the appearance of the person who [disrupted history]! He killed Xu Yun!"

"Originally, it was impossible for Xu Yun to come up with anything interesting... Can a person of his level handle the hibernation cabin? Let alone him... Even the top scientific research genius in the world can't do it. Maybe I can get the hibernation cabin filling fluid on my own!”

…

Wow.

Ji Lin threw away the June issue and picked up the July issue:

"I quite like Xu Yun. Xu Yun often came to my sister's house when I was a child, and he would bring me a lot of books every time he came."

"My sister even laughed at him at the time, saying how could anyone give books to children and that he was a stubborn nerd."

"But actually, I like all the books Xu Yun gave me. He is indeed not a very smart person, either in terms of research or emotions... But like my sister, I don't hate such people."

"He met me for the first time and gave me a set of "Twenty Thousand Leagues Under the Sea". He said it was a children's book, but the one he bought was not a children's version. I really liked this set of books and even liked the content in it. The plot is believed to be true, so I look forward to Xu Yun coming home every time...I look forward to what books he will bring to me next time."

"It's just that after Xu Yiyi's accident... you two fell out and he never came again."

The old man chuckled, his eyes full of memories:

"So, Xu Yun can be regarded as your first writing teacher? I have never heard him talk about this."

"No wonder you, an owl who never leaves the nest, came all the way to the East China Sea to attend his memorial service without saying a word after hearing the news of Xu Yun's death."

"This is not like you at all. You didn't even think about how to plan your itinerary to avoid the group of book fans and reporters. I saw the reports published by major media... You were stuck in traffic for a long time at the airport, and you were also blocked by reporters. I took a lot of photos. Now you are in the headlines of many entertainment news, and they are discussing your relationship with Xu Yun."

Wow.

"So what if we get a photo?"

Ji Lin threw away the July issue, picked up the August issue, and continued to do Sudoku in the new issue:

"It's not that I'm shameless, I'm just too lazy to go out."

"If I can meet some interesting things or interesting people... I'm actually quite willing to socialize."

"It's just that my sister passed away early, and Xu Yun was driven away by you... I have no interest in socializing."

"I was very disappointed when I knew that Xu Yun would never come to me again. Although he was not very talented in scientific research... he was a scientist after all, and his knowledge and insights were very important to me who was only a few years old at the time. “It’s still very shocking.”

…

Speaking of Xu Yun.

The old man's expression quickly dimmed again:

"Actually, things shouldn't have developed like this..."

"I've been waiting for Xu Yun--\u003e\u003e

Looking back on that day, many wealthy businessmen and capital were actually interested in Xu Yun's research and wanted to fund him. But after I learned about it, I stopped them halfway. "

"I thought there would be a day when he couldn't hold on anymore, and he would always change his mind and come back to find me. Even if your sister passed away, in fact, I have always treated Xu Yun like my own son. "

"There's really no difference. Although I don't have a child, you adopted him. But if I had a child, I think the best I can do to him is the same as I treat Xu Yun."

"The day Xu Yiyi's accident happened, I felt more uncomfortable than Xu Yun. Since you know everything, just tell me. After all, she is also my granddaughter. I don't wish her well?"

"At that time, I invited all the experts in this field from all over the world to Donghai City. One after another, I chartered a plane to invite them all to come over for consultation with Yiyi. But none of the experts said there was hope for recovery...none."

The old man closed his eyes and lowered his head.

Wow.

The August issue of "Mathematical Monthly" was thrown to the ground by Ji Lin.

The Sudoku in this issue of the magazine is the "Killer Sudoku" with the highest level of difficulty. There are no traces of alteration on the clean pages.

"So, can you tell me the answer now?"

Ji Lin picked up the September issue of Mathematics Monthly, but did not open it.

For the first time, he stopped what he was doing.

Looking up at the old man:

"[Why...you want to kill Xu Yun?]"
