He turned around and was about to walk to the bathroom when he suddenly heard a voice as weak as a mosquito: "Wait... wait until I finish frying the last... this dish..."

Qin Ke almost stumbled. Did he have something wrong with his ears? Or did Ning Qingyun say that we can eat after I finish frying the last dish and asked him to take a bath quickly?

He turned around in shock, only to see that Ning Qingyun had turned around and continued cooking.

But if it wasn't Qin Ke's illusion, he clearly saw that the girl's skin turned pink due to shyness, her cooking movements were no longer as calm as before, and even the sound of the shovel and the wok seemed to be a little more disappointing.

The nervousness and panic of a person's heartbeat speeding up.

…

In the end, the dinner time for the two of them was postponed for a long time. It was not until after nine o'clock in the evening that Qin Ke came out of the kitchen after washing the dishes. He was humming children's songs and felt refreshed. Ning Qingyun also put on matching clothes with him.

The couple in nightgown were lazily sitting on the sofa, slowly flipping through magazines. The girl's pretty little face was flushed, showing her indescribable charm and cuteness.

"Have you recovered your strength?"

"Yeah." Ning Qingyun lowered her eyes and responded shyly.

Qin Ke sat over and hugged Ning Qingyun. The touch of the warm soft jade made him particularly happy: "To be honest, I found that there have been some changes since you last saw your mother."

"Yes...is there any?" Ning Qingyun's face was hot, her eyes wandered, and she did not dare to meet Qin Ke's eyes.

Qin Ke chuckled, vaguely guessing something in his mind. No matter what, such a change made him very happy and surprised. He was afraid that if he continued to talk about it, he would make Xiao Baicai extremely shy, and this benefit would be gone in the future, so he changed the topic with a smile:

"By the way, have you submitted the paper on 'Three-layer Infinite Flow Loop Algorithm'?"

"Well, I submitted it to the "Annual Review of Mathematics." Seeing that Qin Ke did not continue the topic, Ning Qingyun's shame a little lessened.

Her reserve and shy character are deep in her bones and difficult to change, but after her mother talked to her that day, she agreed with her mother's words and was willing to work hard to make changes for Qin Ke.

It's just that this kind of thinking is too shameful. As a girl, how can she have the nerve to admit it?

The two chatted for a while about writing a computational seed course, and Qin Ke's cell phone suddenly rang.

Unexpectedly, this was actually an overseas long-distance call from Professor Tao.

"Professor Tao, good morning." Qin Ke answered the phone and greeted with a smile. It is now around nine o'clock in the evening in Xia Country, and it is around nine o'clock in the morning in the United States.

"Qin Ke, I didn't bother you. Your article "Ten Questions about the Famous Mathematician Obadiah Shawn" was so well written. I tried to use the method mentioned in it and found several articles.

I tried the paper that I felt was suspicious, and sure enough I found something fishy." The slightly excited laughter of Professor Li Tao from a distant country came over the phone:

"It's a pity that I really don't have your skills and can't find out who the other party hired as the shooter. Please tell me quickly, how did you determine the list of shooters for Obadiah Sean? This is really incredible. Last night

I stayed up all night thinking about this. If I don't figure out how you did it, I'm afraid I won't be able to sleep tonight."

Qin Ke then remembered the battle article he uploaded to arxiv in the morning, but he experienced something wonderful after waking up, which made him forget about it for a while.

While he gestured to Ning Qingyun to open the arxiv website, he explained with a smile: "This is difficult to say, but it is also easy to say. I started investigating from the most likely, the circle of professors in the country's mathematics community.

. I think it is unlikely that Obadiah Sean will find a gunman through the Internet. He must be looking for someone who knows each other in real life. After all, hiring a gunman and being a gunman are both shady things. As long as they hit it off.

, neither side can betray the other."

"It makes sense. This is indeed the direction with the highest probability." Professor Tao clapped his hands in agreement.

"I have analyzed the subdivisions of each of these gunmen's expertise in the paper, and asked my assistant to select from the tens of thousands of professors in the country's mathematics circle based on the subdivisions of their expertise..." Qin Ke did not mention Wei Guang's.

The name was changed to assistant, and Professor Tao didn't ask in detail. In his mind, if Qin Ke didn't have a team of assistants, it would be almost impossible for Qin Ke to complete such a tedious task.

"In this way, most of the people have been screened out. Then, considering that these shooters are all good in level and strength, we can also eliminate professors who have only published papers in low-level academic journals. In this way, only a few hundred people are left. Remove again.

Those senior professors who are very famous and cannot take risks for profit only retain the list of those who have been associate professors for a long time and are middle-aged, with some fame but not much fame..."

Professor Tao suddenly realized: "Yes, the gunman must have reached a bottleneck in his career for various reasons, with no hope of being promoted to full professor, and because he was greedy for the huge profits promised by Obadiah Sean, so he agreed to be a gunman to write the paper for him.

After all, only they and Obadiah Sean knew about this matter. Neither party could betray the other party. It was obviously a low-risk and high-yield matter... If I hadn't met an incredible math master like you, no one would have discovered it!

"

Qin Ke said with a smile: "Professor Tao's thinking is really quick, that's about it. I asked my assistant to use some mathematical formulas and derivation habits as keywords to search for papers in related fields on the Internet. I compared them again and found out that

These nine gunmen were found one after another. In order to avoid wrongly accusing good people, I also specially found all their published papers and checked them one by one. I confirmed that they were indeed helping the evildoers, and then I named them one by one in the papers."

Professor Tao asked for many more details, especially mathematical analysis, statistical derivation details, and how to analyze a person's mathematical thinking from derivation habits, and then he said with satisfaction: "Thank you so much, Qin Ke, I have learned a lot more

, Hahaha, next I will apply what I have learned and crack down on fakes everywhere! By the way, you wrote a paper related to n-s equations and sent it to the "Annals of Mathematics", right?"
Chapter completed!
