She saw the tendons and flesh of this person's body, and she didn't look like a top student, she felt more like a big-chested and brainless sports man, deliberately rubbing the popularity of Beijing University, and hurriedly salvaging the wind for her future alma mater: [What's the matter, my best friend and I have to study at Beijing University, it's not! ] 】

Cousin Hu Keer deliberately joked: [Then do you have 680? 】

Bubble Ke: [I didn't [smile] but my girlfriend took the college entrance examination 685 haha, and also learned to compete in mathematics [dog head]]

Cousin Hu Keer: [Yo, it's amazing, then you hurry up and let your girlfriend talk to him hahaha, anyway, I can't talk about it this day [dog head]]

Hu Keer glanced at the photo of the man again, although he knew that Ning Sui should not be interested, but he still turned his head and said to her with a smile: "I heard my sister say that this software called Qingguo has been very popular recently, or you can also register an account, maybe you will find the true destiny." ”

Hu Keer is the kind of person who has strange ideas in his head, has no motive to be a scumbag, but believes very much that he has the talent to be a scumbag.

Her vision is to indulge in the present, and she likes the dark chat process before she is about to start a relationship, so when she is not with Xu Zhuo, she also likes to hold various social media and chat with people, and it is not unusual for her to show a strong interest in "Qingguo".

If she weren't single now, she would have wanted to rush up and nag herself.

But Ning Sui and Hu Keer are completely opposite, she prefers offline more than online, and she has never even met in person, so the other party is an unembodied entity, feeling like a robot, and it is difficult to have a long-lasting common topic.

Ning Sui's most impressive online communication was only the two years of high school, and the exchange of letters with her pen pal on the Internet.

At that time, every contact made her feel fresh and different, and she never felt bored.

Although she didn't know who the other party was, she also knew that he must be a big guy, because that person's idea of solving the problem was particularly ingenious, to the point, and the steps were concise and powerful.

Ning Sui thought about hooking up with the other party at that time, so he asked him for advice in a private chat.

There was no reply at first, the big guy was super cold, and it is estimated that he received many private messages from strangers at the same time, and he didn't look at it very well.

Later, when Ning Sui reviewed the training questions in Nanjing, there was one question that she couldn't figure out if she could use another method, and remembered that the big guy had answered a similar question on the homepage before, so she took a photo of her test paper and sent it over.

After waiting for many days, she thought that this private message had sunk into the sea, but she didn't expect to get up and receive a reply.

Nathan: [Well, the attribution of set elements and sets is considered a two-part diagram, which can be found directly using the Katz-Tao inequality, which is simpler than using the Herder deformation. 】

Ning Sui seemed to understand whether he understood or not, and asked a few more questions, and the other party answered them straightforwardly.

Although it was clearly organized, she was embarrassed to ask more, for fear of delaying people's time, so she hurriedly thanked her.

I thought that there should be no follow-up to this conversation, but the other party replied: [How did you come up with this solution, this is not the same as the standard answer. 】

Ning Sui explained: [Someone told me about it before. 】

After a pause, he added: [I think this is very clever, which is equivalent to taking the original inequality as a lower bound with a fixed starting point length of three roads. 】

After a while, Nathan replied in a leisurely tone, "I also think that's pretty clever. 】

Ning Sui was flattered, hesitated for a while, and mustered up the courage to ask: [Then can I ask you questions again in the future?] 】

He said, "Yes. 】

From the second year of high school to the third year of high school, although the frequency of contact between them is not dense, it is indeed uninterrupted, even if it drags on for a long time, she also knows that the other party will definitely reply, which is what makes her feel very down-to-earth.

But unfortunately, in the middle and late semester of the third year of high school, they did not contact each other again. She also became very busy and busy.

Ning Sui's eyelashes drooped, and his thoughts couldn't help but wander a little.

She pursed her lips, pulled out her phone, and stared at the screen for a moment.

Following his previous memory, Ning Sui tapped on the keyboard and searched for the link to the math quiz workshop on the Internet.

Leonhard Euler, named after Euler, feels incomparably relatable. A year later, the math fans are still very active, and almost every minute someone posts a question.

Ning Sui clearly remembered that the account name she had set up was 1212 Coconut, which was very sloppy, named after the date of the penultimate night of the Nanjing training and her nickname.

She was very impressed that day, because she felt that the training time was very long and difficult, so she specially looked at the calendar.

Later, when I returned from the classroom late, I saw that the sky was dark blue, and the snow night was quiet, and the soft sound of falling leaves could still be stepped on on the ground, and the orange street lamps were full of warm light, one by one-

It may be that this picture is too unforgettable, or it may be to commemorate the first trip away from home in 16 years, in short, Ning Sui doesn't know what the reason is, when he registered an account, this date automatically jumped out of his mind.

But she really couldn't remember the password, and tried a few of the usual ones before, but they all didn't get it right.

Originally, it was just a whim to give it a try, but Ning Sui didn't have too much hope, so he simply retreated.

—

There is a famous scenic spot called the corner tower in the ancient town of Xizhou, and several people got up early in the morning to take a group photo there and walked around the town.

It's not as bustling and crowded as the ancient city, but it's still very lively, Ning Sui likes this kind of idle liveliness very much, which not only gives people free space, but also makes people taste the fireworks, even when the crowd is crowded, she can really feel that she is free.

As he walked, he heard Xu Zhuo chatting with Hu Keer in front, and Hu Keer asked, "Do you know what Microsoft's theme song is?" ”

Xu Zhuo didn't know why: "What? ”

Hu Keer hummed the song vividly: "You hurt the word, and you passed by, you love greedily, I love Note weakly~ Also, let me love you, and then powerpoint abandonment~"

Ning Sui: "......" really has yours.

Rao was also amused by Xu Zhuo's serious face, and asked her how she thought of it, Hu Keer proudly said, "Listen to the song a hundred times, and its meaning will come to itself."

Ning Sui ignored the unnutritious trash talk of the two, and heard Shen Qing talking to her on the side: "Did you often travel before?" ”

Ning Sui shook his head.

In fact, there are very few.

Xia Fanghui always felt that it was not safe for girls to be alone outside, even if they usually lived in school, they also sent messages to report when they got the dormitory, so let alone traveling with friends, it was rare to even go shopping in large shopping malls in Huai'an City out of her field of vision.

Ning Sui sometimes envies other classmates, her parents are loosely controlled, and she can do whatever she wants, but many things in life are not black and white, counting the past, Fangfang gave her a lot of love, and it can even be said that she is beyond ordinary doting.

For example, when she is sick, she will take care of her, pour a hot water bottle to warm her stomach, carefully wrap her in a towel to avoid being too hot, and test the water temperature herself before pouring water and taking medicine.

Every week before returning to school, I will stew some soup stock to supplement Ning Sui's nutrition.

Also, every year's birthday, she never forgets it, she will wrap red envelopes with her father, and she will prepare gifts and birthday cakes separately - when her mother is in a good mood, even if Ning Sui wants the moon in the sky, Xia Fanghui will take it off for her.

Ning Sui pursed his lips and asked with a light smile: "You should have been to many places." Is there anything that stands out to you? ”

Shen Qing glanced at her sideways, and said gently: "Actually, it's okay, my high school was mainly in the United States, but I have been to Africa before, sitting in an armored car, and seeing tigers and lions up close, I feel quite shocked." ”

Ning Sui: "Wow, did you take a photo?" ”

He smiled: "Well, I'll go back and find it out for you." ”

"Okay."

After eating at noon, the four of them took a taxi with their luggage and walked to the northeast, and Xu Zhuo in the car casually proposed: "Let's live in Shuangyue Bay, I heard that the homestay is close to Erhai Lake, you can watch the sunrise, and the room is spacious and clean." ”

The young master contributed his ideas for the first time, and Hu Keer was a little surprised: "Okay, you read the review software?" ”

Xu Zhuo: "I just heard that Zhang Yuge and they also live there. ”

"Zhang Yuge?" Hu Ke'er widened his eyes and asked incredulously, "When did you become so familiar with him?" ”

Xu Zhuo coughed lightly, and said with an unnatural expression: "No, I asked Xie Yichen." ”

Hu Keer didn't expect that the lord of this matter would be able to have a good relationship with Xie Yichen, and he felt incredible. And Xu Zhuo was wondering why his opinion of Xie Yichen was getting more and more different?

He still remembers how unhappy he was with this person in his sophomore year of high school, but after only a few days of contact, he actually felt that this person was quite good. is very casual, answering anything, Xu Zhuo heard that Xie Yichen's family conditions are also very good, there is no shortage of money, and he is an excellent person, but he has no shelf.

The two of them had their own thoughts, but Ning Sui raised his eyes and said, "I just took a look at the software, and the score of Shuangyuewan is indeed quite high." ”

So it was decided.

The scenery along the Erhai Lake is also very beautiful, Shen Qing sat in the co-pilot, taking pictures while looking at the road. The road here is wide and winding, with green mountains and water on both sides, lush trees, and scattered houses piled up into a small town, which has a kind of quaint meaning, and the water surface glistens in the sun, and the scenery is boundless.

Xu Zhuo had already contacted Xie Yichen, and Ning Sui didn't do anything more.

The parking lots in Shuanglang Ancient Town are all along the side of the road, which is relatively difficult to enter, and parking spaces are scarce, so it has become a benefit to not have a car.

The taxi stopped at the destination, and Ning Sui just opened the car door and got down, and when he raised his eyes, he saw the young man walking out of the sparsely shadowed courtyard with his pocket in his pocket.

The sunlight penetrated through the green branches and leaves and fell on his handsome dark eyebrows, the broken hair on his forehead was a little scattered, and his expression was still a little unbridled after a nap.

Xie Yichen saw them as soon as he got downstairs, and nodded lightly, which was regarded as a greeting.

Xia Fanghui packed a lot of things in Ning Sui's suitcase, some of which she didn't, whether she could buy them here or not, such as wet wipes, mosquito repellent water, sanitary products, cotton clothes-

God knows what to do with cotton clothes in the summer, and she may feel cold at night, so be prepared.

Ning Sui tried to lift the huge suitcase and cross the threshold, Shen Qing behind him was still talking to the taxi driver, and when he caught a glimpse of this scene, he was about to make a sound and asked her to wait, but he saw Xie Yichen just walking out slowly, stretching out his arm to lift her for her.

Ning Sui thanked him, and looked at him without saying a word, picked up the box, and easily sent it up the steps. Because of the exertion, the shallow muscles and veins on the forearm are superficial.

As soon as she wanted to speak, she bumped into Xie Yichen and turned around, followed the weight, and raised her eyebrows: "What kind of treasure are you pretending, so heavy." ”

Ning Sui thought for a while and said sincerely: "Probably, twenty pounds of autumn pants." ”

“……”

Several people greeted each other, packed their luggage and walked inside, the little girl at the front desk greeted her warmly, and Xu Zhuo showed her the screenshot: "Booked online." ”

The service here is really good, Xiaomei operated in front of the computer for a while, and quickly verified the order. They handed in their ID documents and got their room cards.

Xie Yichen and Lin Shuyu lived in a large suite in the east, duplex, with three rooms, exactly two rooms, and the motorcycle was also parked in front of the hospital.

The front desk looked like they knew each other, so they arranged the two rooms of Xu Zhuo and the four of them in the corridor on the east side, and the corner was next door, which was convenient enough.

Hu Keer took the lead in carrying the suitcase into the room, the two double beds in it were very large, and she put her things aside and jumped on the bed without any image: "Ahhh ”

Ning Sui was a few steps behind her, and Xie Yichen helped push her box into the hallway, stopping at the door very measured and not entering.

Seeing Ning Sui untie the small bag he was carrying cross-body next to the armchair, he half-leaned against the door and asked, "Have you had lunch?" ”

"It's two o'clock, and it's early." Hu Keer bounced up from the bed and said first, "Xie Yichen, I heard Xu Zhuo say, do you have friends here?" ”

Xie Yichen hummed casually, and Hu Keer's eyes lit up and said, "Then why don't you get to know each other together?" ”

She is crazy, the more people there are, the more energetic she is, and when she comes out to play, she is also lively with many friends.

Xie Yichen had no objection, took out his mobile phone and sent a message to Lin Shuyu. Raising his head again, before he could say anything, Shen Qing came over and knocked on the door, and looked at him politely.

I came to deliver fruits, and half of the green grapes and strawberries I bought on the road just now are left.

Seeing that the two of them were standing in the room in a good manner, Shen Qing said, "It's still fresh, leave it for you to eat." ”

Ning Sui smiled politely: "Thank you." You just put it on the table. ”

Xie Yichen leaned sideways, and Shen Qing walked in by the way, putting down the red plastic bag: "I washed it again just now, it's clean, just eat it directly." ”

Hu Keer happily continued: "It's so sweet! Thank you Brother Qing for feeding! ”

Shen Qing: "It's a little meaning. ”

Xie Yichen still lowered his head and looked at his phone nonchalantly.

Lin Shuyu said that Zhang Yuge slept like a pig, and Zhao Yingyao and Zou Xiao didn't reply to the message, so it was better to move freely in the afternoon, and then get together with new friends for a meal in the evening, and he came to make a reservation.
