The top-notch movie queen wears books, disguises herself as a man and is handsome all over the world

After the misunderstanding was resolved, Ethan wanted to invite Qin Jingyu and others to lunch in order to express his gratitude and apology. It happened that they had no money to change and they were penniless. Since Ethan wanted to treat them to a meal, the main idea was that if they didn't eat, they would get nothing.

Ethan admired Qin Jingyu's knowledge, but unfortunately he knew very little about twin prime numbers. He came to this lecture just to try his luck at meeting Professor John Wish.

Doesn't understand prime numbers, but he can make friends with the other person.

"My name is Ethan Adams." Ethan introduced himself. "This is my friend, Jason."

Jason was very enthusiastic about Qin Jingyu, "Hey, friend. You were so handsome just now. Didn't you see how ugly the faces of those top students who looked down on you turned out to be?"

Qin Jingyu's remarks in the lecture made those who looked down on her slap her in the face, not to mention how happy that moment was.

He thought that his impression of the Chinese people as weak was going to change.

"Thank you." Qin Jingyu. "My name is Qin Jingyu, and these are my partners, Chen Shaochuan and He Qian."

Ethan's amber eyes were deep and passionate, looking at He Qian and Chen Shaochuan, "Hello."

He Qian heard that Ethan's Chinese was pretty good, so she praised: "Your Chinese is very good. Have you learned it specifically?"

Ethan shook his head: "No, my mother is Chinese. Her ancestral home is from Imperial City of China, but she moved her family to Country K with her grandfather at a very young age."

Speaking of Imperial City, He Qian said excitedly: "Your mother and Qin Jingyu are fellow villagers."

Ethan: "Qin, are you also from Imperial City? I haven't been to China yet. I hope to have the opportunity to travel in the future."

Qin Jingyu nodded, "When you come to the Imperial City in the future, you can find me."

Ethan treated them to a sumptuous lunch. He Qian was still a little embarrassed. Qin Jingyu said that he could treat them to the meal after the competition. He Qian said yes and would exchange money with Assistant Wang then.

After the meal, the library of Princeton University could not be entered without a student ID card, so everyone had no choice but to return to the hotel in frustration.

Jason saw the backs of several people leaving and said to Ethan next to him: "Brother, I feel like you have met your opponent this time, and he is a strong opponent."

Ethan looked at Qin Jingyu's tall figure and curled his lips: "Didn't you say yesterday that Chinese people are weak?"

Jason spread his hands: "You know, that's my prejudice."

Ethan: "Twin prime numbers are an area I don't understand, but I'm very much looking forward to competing against Qin and his companions in the competition."

Jason: "Good luck!"

After Qin Jingyu returned to the hotel, he took out the manuscript paper and crossed out the dislocation method and the principle of inclusion and exclusion. Although Professor Thomas used the principle of inclusion and exclusion to make a trap, he also made her understand that Euler's method could not be followed. On the dislocation method, something is missing in the middle. What is it?

886 suddenly jumped out: [Host, you still have useless point rewards. The twin prime number proves that the host is almost halfway through. Do you want to redeem the fragments of the twin prime number conjecture? 】

Qin Jingyu has now entered an alley, and the time to prove the twin prime number conjecture is limited, so he may need to use points to exchange for fragments.

886 continued: [I hope the host will not be stingy with points to redeem rewards, rewards for twin prime number fragments,]

Qin Jingyu: [I choose to exchange for twin prime number fragments*4. 】

886: [Is the host sure that he will use the points to exchange for twin prime fragments*4? 】

Qin Jingyu: [OK. 】

886: [Okay, congratulations to the host for obtaining twin prime number solution fragments*4. Warm reminder: The system only provides fragments of problem-solving ideas. Please use the fragments reasonably. 】

As soon as he finished speaking, Qin Jingyu suddenly had something in his mind.

1. Feminine composite number theorem and feminine prime number theorem. 2. Positive composite number theorem and positive prime number theorem. 3. Overview of the distribution of the four equal numbers of yin and yang in the natural number sequence. 4. The interpenetration of four types of equal and large numbers.

It is a fragment of the argument for twin primes.

What she didn't expect was that twin primes could actually be divided into yin and yang primes. She had checked so much information before, but couldn't find it. It seemed that the academic world had not yet reached this point in research, so there was no record of this information.

By the way, there should be records about yin and yang prime numbers in that collection of ancient and modern mathematical thoughts.

Soon, she found the relevant records in the collection of ancient and modern mathematical thoughts. Although it was very brief, combined with other documents, it was enough for her to understand the argumentative relationship between yin-yang prime numbers and twin prime numbers.

So now, she just needs to combine these and hopefully prove twin primes?

At this glance, I missed dinner, and it was coach Shen Tu who brought the meal.

Qin Jingyu opened the door, and Shen Tu looked into her room. Sure enough, he saw the books and manuscript papers on her desk. He kindly reminded: "Jingyu, I know you are very smart, but I hope you don't miss this opportunity." Business."

She took off her glasses, rubbed her eyebrows, and said a little tiredly: "Don't worry, coach, today is the last night. After the opening ceremony tomorrow, I will prepare for the game with all my heart."

Shen Tu smiled slightly, "I believe you can do what you say."

As he spoke, he handed her the dinner he packed from the hotel, "Your family specifically told me to keep an eye on you. No matter what, you must eat well."

Qin Jingyu was stunned when he heard this, "In my family?"

"The president of the Bo Group is your brother-in-law, right?"

She nodded.

"His assistant contacted me and asked me to take care of you during the competition abroad."

Qin Jingyu didn't expect that Bo Hanting was still carrying her on his back, asking the coach to look after her when he was playing outside.

It's a shame that he, a busy man, can be so careful.

Shen Tu continued: "So, don't let coach me and your family worry."

Qin Jingyu thought that it must be the last time she competed in Zhonghai City. She locked herself in her room for a day and a night and left a psychological shadow on Bo Hanting. She scratched the back of her nose and said, "Don't worry, it won't happen this time." Got it."

Shen Tu nodded: "That's good."

After he finished speaking, he seemed to remember something again, "By the way, there is one more thing."

"Ok?"

"I heard that your lecture at Princeton University this morning made a big splash, right?"

Qin Jingyu: "Uh..."

Shen Tu raised his eyebrows: "Not bad, well done!"

Qin Jingyu: "..."

After seeing the coach off, she took out her phone, opened Bo Hanting's chat box, thought about it, and sent a message of thanks: [Thank you, uncle, I will take care of myself. 】

There was a time difference between country M and the Imperial City. It was early in the morning and he should have gone to bed, so after sending the message, she finished the meal in a few mouthfuls. She still had some points of argument that she didn't want to understand, so she took advantage of tonight to read them. Since she agreed to Professor Shen, she will put the twin prime numbers aside after the opening ceremony tomorrow.
