Do you understand Euclid today?

Many years ago, when elementary school Jilin Qianshu quarreled with his classmates, he scolded others for their poor grades in math, and would mock him with the phrase "Your math was taught by the physical education teacher".

The current report is that he was caught by the physical education teacher, and he couldn't help but put a string of whistles around his neck, and somehow walked to the track and field to help him with the physical education class.

The physical education teacher probably stretched to the limit that his stomach could bear, and only sent the person to the sidelines, and ran back with his feet without explaining to the students, in a strange posture with a hint of embarrassment.

Lin Qianshu watched his back, feeling a sense of sadness and sorrow.But when he turned around and saw fifty pairs of curious eyes staring at him, he was still a little nervous.

"That...cough," Lin Qianshu cleared his throat, put his hands behind his back, and said with his head held high, "Your teacher Wang is not feeling well. I'll give you a physical education lesson."

Lin Qianshu looked at the students in the team while talking, and his eyes fell on the familiar person wearing blue glasses at the farthest end, only then did he realize that the class he was substituting for was Senior One A.

She is her direct junior brother and sister, and she is also the main member of the mathematics competition club.

Facing such a group of people, Lin Qianshu was not nervous.He swallowed his saliva, wiped the sweat that came out of his hands unconsciously, and desperately recalled what the teacher asked everyone to do when he was in physical education class: "Sports committee members form a team!"

The dark-skinned boy standing at the forefront of the line trotted to Lin Qianshu's side, and reminded him in a low voice: "Mr. Lin, we have assembled and completed the team."

"Oh, the team is finished." Lin Qianshu nodded, frantically recalling what the team was going to do next, he asked tentatively, "...Then everyone run five laps first?"

As soon as these words came out, the whole class immediately heard a gasp.Lin Qianshu's heart tightened - did he say less?

"Huh?" Lin Qianshu frowned, and was about to ask the reason. Seeing Lin Qianshu's expression, the sports committee member felt a chill down his spine, and raised his voice to sound the alarm to the students: "Comrades , What are you still doing in a daze? Hurry up and run!"

Hearing the shout of the sports committee member, all the students in Class A of Senior One turned to the right and ran around the track and field with big strides, but the expressions on everyone's faces looked so unlovable.

It was only after everyone started running that Lin Qianshu suddenly realized that the physical education teacher dared to let everyone run five laps before class because the meeting place was set on the basketball court.A lap of the basketball court is only about 100 meters long, while a lap of the track and field field must be at least 400 meters long. My voice tripled the distance.

...This is a mess!Lin Qianshu couldn't help but support his forehead, and stopped the elementary school tyrants in time when they were about to run the third lap, and looked helplessly at them who were panting: "Why don't you bargain?"

Everyone had a dazed look on their faces, as if they were saying, "Is it still possible to do this?"

"Next time the teacher makes an unreasonable request, you must learn to refuse it bravely." Lin Qianshu taught them.He thought to himself that he was not so innocent when he was a freshman in high school. The teacher told him to run three laps, at least he would automatically come out and pretend to tie his shoelaces in the middle of the first lap, and wait until everyone ran to the third lap. Stand up and blend into the queue, saving two laps once you come and go.

After the jog was over, Lin Qianshu took everyone for half a circle. Thinking that the physical education teacher should be back after solving his personal problems, and thinking that the students were almost overexercised by him just now, he simply announced with a big wave of his hand: "Disband, let's move freely!"

The boys who were pale and loveless just now suddenly jumped up and rushed to the sports equipment room cheering, all of them seemed to be able to run at least another [-] laps.Lin Qianshu was left in a daze - was he being played again?

A group of boys took out basketballs from the equipment room, cheered and rushed to the basketball court to play basketball.The rest of the girls played badminton together in twos and threes.Lin Qianshu stood on the track and looked around, and saw that there were also a few people who didn't like sports and hid in the shade of the trees. They were all holding palm-sized information books in their hands, and it seemed that they were hurrying to study.

Sure enough, no matter what the occasion, there will always be people who study hard.Under the shade of a tree, Lin Qianshu saw Guan Ming. This young student was sitting cross-legged next to the tree trunk, burying his head in a problem.

It seems that only Guan Ming is the most familiar person.Lin Qianshu walked up to Guan Ming and sat down cross-legged. Curiously, he leaned over to take a look, and found that he was brushing up questions from a magazine titled "Mathematics is Wonderful".

Lin Qianshu felt a tinge of admiration for Guan Ming. After all, at the moment, Lin Qianshu felt that his view of mathematics was only "odd".

Guan Ming was unaware of Lin Qianshu's approach, he was so focused on the topic, he could tell from the look on his face that he was struggling.

Lin Qianshu rested his chin and looked at it for a while, but soon became bored, and involuntarily glanced at other places.In a blink of an eye, he saw the young man sitting under the tree next to him secretly looking at him.

The young man had a shaved cropped head, which was rarely seen at this age, and his expression was a little shy. Seeing Lin Qianshu's gaze, he avoided it in a panic, and couldn't help turning his gaze back after half a minute. .Almost like a little hamster hiding something.

The eyes of the two collided again, and the boy's face quickly turned red.

Why does it feel like I'm teasing him.Lin Qianshu turned his eyes away speechlessly, and continued to watch Guan Ming do the math problem.

About two or three minutes later, Lin Qianshu heard rustling noises around him, and then his sleeve was pulled.

Lin Qianshu turned his head and saw the young man who was sitting under the shade of the tree next door moved to his side, with an embarrassed expression on his face: "Lin, Mr. Lin, how much did Brother Jiang take the math test this time?" ?”

Lin Qianshu looked at this strange boy and thought to himself, I don't know how much your brother passed the exam.However, since the title "Brother Jiang" is really representative, he has heard it no less than ten times in the past three days due to amnesia. He tentatively asked, "Are you asking about Jiang Yixing?"

"Well," the boy continued to maintain his shyness and nodded, "I asked him yesterday, and he said that this time he has made great progress."

To be able to choose a D in the question numbered 123 is not a historic leap.The corners of Lin Qianshu's mouth twitched, and he was about to speak, when Guan Ming next to him suddenly dropped his pen heavily, and sneered, "Progress ass."

Hey, high-achieving students can even swear.Lin Qianshu turned his head to look at Guan Ming unexpectedly, feeling that his character set had collapsed.

Guan Ming didn't keep his voice quiet when he spoke, and the boy sitting on the other side of Lin Qianshu naturally heard it too.He stood up and looked at Guan Ming with dissatisfaction: "Guan Ming, don't hold such big prejudices against Brother Jiang, okay?"

"Xiang Xiaojun, don't worry about the two of us. And I advise you, you should keep your eyes open," Guan Ming grabbed his pen and snorted again, "You chase after his ass all day long, you see Did he give you heart and soul? He is a white-eyed wolf!"

Xiang Xiaojun's face flushed red, and he roared, "You are not allowed to say that about me, Brother Jiang!" He rushed to Guan Ming angrily, and Lin Qianshu stood up quickly, posing as if he was ready to fight. Pull up anytime.

Xiang Xiaojun rushed up to Guan Ming, suddenly braked suddenly, sat down, straightened his posture, and looked down at the question that Guan Ming was doing.He held a section of the tree pole in his hand, and said, "The answer is square root three."

Now Guan Ming's face turned red with anger, he threw down his pen again angrily, and glared at Xiang Xiaojun: "I know the answer is square root three, so you don't need to tell me!"

"But you don't know why the answer is square root three." The expression on the shy boy's face turned into a triumphant look, and he looked like he deserved a beating, "I know, I won't tell you if you call me Brother Jiang! "

Lin Qianshu, the melon eater, was amazed.He had heard a word called "fairy fights" before, but now he saw it for real. He had never seen a way of solving math problems to make others angry.

"Do you think I'm stupid? This question can be solved with vector coordinates. I'm just thinking of solving it in other ways!"

"I didn't use the vector coordinate method, and I won't tell you if you beg me."

"I won't beg you, I'll piss you off!"

Chirping.Chirping.Lin Qianshu felt that two cicadas were screaming in his ears, which made his ears hurt.So he took a step back facing the two of them, and put a little distance between them.

As soon as he took a step back, Lin Qianshu felt the sound of howling wind from behind him. He lowered his head to look at the ground, and there was a shadow on his back, accompanied by a terrified shout from a boy on the basketball court next to him: "Mr. Lin! Be careful! ah!"

Lin Qianshu turned his head subconsciously when he heard the sound, just in time to be hit by a basketball flying in front of him.

The basketball hit his head and bounced off, leaving a sharp pain where it hit.Lin Qianshu was driven down by inertia, and when he fell, he even had the thought of laughing at himself: This is a good time, I'm afraid I'm going to lose my memory again...

Before falling into a coma, Lin Qianshu's last memory was the scene of a group of young men throwing basketballs and rushing towards him in horror.

"Drip-drip--"

Hearing the voice in his ears, Lin Qianshu opened his eyes in a daze.

What caught the eye was the white ceiling, and the strong smell of disinfectant filled the nostrils.

Did you go to the hospital by yourself?

Lin Qianshu moved his fingers and tried to sit up by himself. After trying many times, he was discouraged and found that he didn't seem to have much strength. He was sweating again from this effort, and passed out again dizzily.

However, when Lin Qianshu woke up again, he found that he had moved his position again.
