Do you understand Euclid today?

Lin Qianshu entered the examination room on the preparatory bell.

After ringing the preparatory bell, there were still few candidates in the examination room No. 10, and many seats were still vacant. Lin Qianshu took a cursory glance and found that there was a whole row or even the very front seated with a boy looking down at a basketball magazine.

It seems that Nanshi Gao's style of arranging the examination room according to the results has remained the same for seven years. Exam room No. 10 was the last exam room of the entire grade, so it was natural that all kinds of gods and monsters were gathered.

Lin Qianshu was thinking, when suddenly there was a rush of footsteps at the end of the corridor, mixed with the characteristic rough voice of a few adolescents shouting "I'm going to be late, I'm going to be late".Lin Qianshu watched the black whirlwind blow from the back door to the front door and stopped, and the leader's voice sounded like a bell: "Report!"

Lin Qianshu coughed, deliberately put on a serious face and put on a majestic look: "Come in, don't be late for the end."

The boy hurriedly nodded and rushed into the examination room, aiming precisely at the one who was still reading the magazine: "Tank, where should I sit?"

The boy called "Tank" was still staring at the magazine, and pointed his hand back, precisely pointing to the seat diagonally behind him.

"Thanks," the boy laughed and thanked, then asked, "And where is my Brother Jiang sitting?"

Tank was still reluctant to put down his beloved magazine, but he spoke: "The last seat in your row."

For some reason, Lin Qianshu and the boy looked towards the back together, and there was indeed an empty seat there.

After scouting the terrain, the boy turned his head to the door and said, "Brother Jiang! The seat is found, let's come in for the exam!" The flattering tone was like that of a senior manager.So Lin Qianshu went to look at the prince at the door curiously.

The "black whirlwind" blocking the door just now has almost disappeared, and there is only one boy left leaning against the door lazily playing with his mobile phone.Hearing the people inside calling him, he put away his phone and stood up again, raising his eyes to meet Lin Qianshu's.

When the boy raised his eyes, Lin Qianshu was stunned again.

The boy's appearance gave Lin Qianshu an inexplicable sense of familiarity, especially those obsidian eyes, he always felt as if he had just seen them today.

However, the preparatory bell had already rang for the third time, and Lin Qianshu didn't care to think about it. The radio began to urge the students to put their backpacks and review materials in the designated place, and the invigilator opened the sealed bag.He said, "Everyone, bring your things up," and hurriedly began to open the sealed bag.

Most of the test room No. 10 were gods who just brought a pen and went into battle with ease. Only the boy called "Tank" closed the basketball magazine and put it on the podium with a regretful face, and returned to his seat with regret.Lin Qianshu opened the sealed bag, and noticed that the familiar boy had already sat down in his seat, and was playing with the eraser in his hand with a bored expression.

The radio bell rang for the fourth time, and a mechanical voice reminded: "Please ask the invigilator to distribute the test papers."

Lin Qianshu looked away, and handed out the papers to each candidate's desk in a strange manner.

After all this is done, the bell for the official exam rang.Lin Qianshu breathed a sigh of relief, returned to the podium and sat down.

The exam in the first year of high school is also mathematics.Lin Qianshu took a look at the sample paper curiously, and finally found a topic that he could understand.He was a little excited, but he didn't intend to show his talents for it - after all, he was here to invigilate the exam, not to take the exam.

Looking at the many students under the podium who were bitter, bitter, or loveless, Lin Qianshu showed a peaceful smile, slowly took out the mobile phone from his pocket, and put it on the table in a very ceremonial manner .

Seven years later, the mobile phone has undergone a lot of changes compared to seven years ago. Lin Qianshu barely understood that the inexplicable unlocking was due to face recognition, but he didn't know any of the fancy software installed in it. Crossed out, and finally decided to start with the photo album to learn about the life trajectory of this "Lin Qianshu".

The photo album really has surprises.Lin Qianshu found a lot of good things in the photo album.This "Lin Qianshu" seems to have obsessive-compulsive disorder. In the photo album, he has built many photo albums by category, including "University Memories", "Unforgettable Events" and "Chat History".

Lin Qianshu opened the "University Memories" album first, and the first photo shocked him deeply.

In the first photo, "Lin Qianshu" was standing under the gilded signboard of Nanling University with a big bag on his back, and said "yeah" to the camera.The silly smile at the corner of his mouth made Lin Qianshu want to say "Is there something wrong?"

Fortunately, in the next photo, Lin Qianshu saw that he was gradually getting rid of his stupidity.Some were giving reports on stage, some were wearing doll costumes and holding headgear, and some were wearing formal suits... Lin Qianshu looked over one by one, as if seeing his beautiful life in college.

What impressed Lin Qianshu the most was that he was standing in front of the podium of the National College Math Contest, holding a shiny silver medal in his hand.

To his death, this Lin Qianshu was not only admitted to the Department of Mathematics of Nanling University, but even won a prize in the National Undergraduate Mathematics Competition.The more Lin Qianshu thought about it, the more terrifying he felt. This couldn't be his parallel world, right?

Fortunately, there is only one license plate for the mathematics competition award that made him panic. One more stroke, and the next one is a graduation photo in a bachelor's suit.

Based on time conversion, these graduation photos should have been taken a few months ago.Lin Qianshu looked at the people who were shoulder to shoulder with him, with an inexplicable sense of intimacy in the strangeness.

Of course, among a bunch of strangers, Lin Qianshu still locked on a familiar figure with incomparable precision.

Jiang Yizhi was actually a college classmate with him.And judging from the distance and movements of the two of them in the photo, the relationship between the two seems to be much better than Lin Qianshu imagined.

Jiang Yizhi also took the exam at Nanling University?Lin Qianshu was slightly surprised.You must know that before crossing, Jiang Yizhi was the super No. 2 in the first grade who was always more than ten points higher than the No.[-] who took turns sitting in the village. Even Yan Kaiyue asserted in the class many times that as long as Jiang Yizhi maintains this learning state , During the college entrance examination, Qingbei can choose whatever he wants.

Although Nanling University is good, it is certainly not as good as a world-renowned university like Qingbei.What's more, being a classmate with a scumbag like himself who has repeatedly failed in the grades, Lin Qianshu felt that this was the fall of a generation of academic gods.

Thinking about it, he even smacked his lips regretfully for Jiang Yizhi.

After admiring the "University Memories" photo album, Lin Qianshu opened the "Unforgettable Events" photo album with more than enough satisfaction.There were even more photos of events piled up here. What caught Lin Qianshu's attention was that Jiang Yizhi appeared in almost every other photo. He and Jiang Yizhi could be described as "inseparable".In many selfies, he was standing in front of him holding his mobile phone, and Jiang Yizhi stood not far behind him and turned slightly sideways, with no sign of being threatened in his eyes.

Going to a university by yourself will really settle the feud with your arch-rival?Lin Qianshu rubbed his chin, but couldn't think of a reason.

After browsing the first two albums, Lin Qianshu clicked on the album that said "Chat Records". It contained screenshots of WeChat conversations. Lin Qianshu quickly flipped through it, feeling that the contents inside were somewhat inexplicable.The screenshots are all from a conversation between myself and a person nicknamed "A Jiang", talking about trivial matters, either he asked me to bring a bottle of soy sauce back home, or I asked him to buy a midnight snack and go back to watch the game together. He replied with an emotionless "yes".

...Why is this Lin Qianshu hoarding all kinds of rubbish in the photo album?

Lin Qianshu was depressed for a few seconds, and then began to think about who A Jiang was.Judging from the conversation, this is obviously a person who has known me for a long time. The two of them even live together, and they even cook together, go to the supermarket and so on.

Could it be that Lin Qianshu saved these pictures as a memo to remind himself not to forget to take things home?

Lin Qianshu thought about it, and opened WeChat involuntarily.I found that in addition to "love and love the Lin family" at the top of my chat seven years later, there was another "A Jiang".He clicked into A Jiang's circle of friends to look for clues, but found that there were only two or three math-related forum messages that were reposted and shared.

After searching for a long time, Lin Qianshu finally found the answer from A Jiang's wechat account - A Jiang's wechat account is jiangyizhi0214, Jiang Yizhi 0214, it looks like a combination of name and birthday.Ganqing not only became friends with Jiang Yizhi, but even became friends who were close enough to live together after graduation.

But the two of them are both locals of Nanling, so they want to leave their home and rent together?Lin Qianshu was a little confused.He was about to dig through his WeChat address book again, when there was a "bang bang" sound in the silent examination room, which made him lose his grip on the phone. With a shake of his hand, the phone slid onto the table.

He raised his head and found that the one who made the noise was the last boy who walked in just before the exam started, so he stood up, walked towards the boy with a straight face, and was about to teach him a few words, when the examinee raised his head, Lin Qianshu Suddenly remembered why he felt so familiar to me.

The boy's black pupils were exactly the same as Jiang Yizhi's eyes in the album, and even the expressionless faces of the two were [-]% alike.

Lin Qianshu was shocked by his miraculous discovery, and his originally rigid face gradually forgot the expression.

The young man looked at Lin Qianshu who was approaching on guard. After being on guard for a long time, he found that the other party was still staring at him motionlessly. This made his neck stained a thin layer of red, and he stared at Lin Qianshu in embarrassment. Qian Shu took a look, looked back and looked down at his paper.

Lin Qianshu blinked and came back to his senses.He coughed lightly, and continued to put on a serious posture: "What's going on?"

What Lin Qianshu didn't expect was that the boy sitting in front of the boy tremblingly raised his hand, and said in a low voice, "I threw the eraser too loudly, Brother Jiang is maintaining discipline in the examination room. "

Lin Qianshu laughed angrily: "Oh, then you Brother Jiang is still a member of the examination discipline committee."

The young man snorted, ignored Lin Qianshu's ridicule, and drew numbers on the draft with a pen.

"Noise is not allowed in the exam to affect other students." Lin Qianshu reminded, then turned and walked to the podium, halfway glanced at the test papers of the candidates on both sides, all of which were empty without exception.

It seems that the examination room No. 10 after seven years still maintains the traditional standard.Lin Qianshu breathed a sigh of relief, and the expression on his face softened unconsciously.

Recalling what he didn't know how to do in the examination room of the third year of high school, he even developed a feeling of sympathy with this group of students who had only met each other for four or ten minutes.

The author has something to say: Brother Jiang, dragged his family to come and fall in love, and his younger brother still dragged his feet. This is in stark contrast to Chen Shi, who is assisted by Harry next door.
