Do you understand Euclid today?

Silent air permeated the room between the four of them.

Radar looked at Jiang Yixing, then looked down at the topic, and laughed awkwardly: "This topic...is interesting."

At this moment, piles of repeated words were flying in Lin Qianshu's mind: Jiang Yixing, solved this problem.

To solve this problem, not only a systematic and comprehensive understanding of function knowledge is required, but also a flexible thinking is required.Both Lin Qianshu and Guan Ming were defeated by the latter. Who would have thought that the most thoughtful person among the four present would be Jiang Yixing.

Seeing that Lin Qianshu and Guan Ming were still not moving, Jiang Yixing impatiently picked up the pen again and wrote a few lines of problem-solving process under the formula.He returned the pen to Lin Qianshu: "Should I know how to do it now?"

Lin Qianshu took the pen numbly, and passed it to Guan Ming like a certificate of honor.

Guan Ming took the pen, took a deep look at Jiang Yixing, and started working on the question.

The competition classroom became very quiet, only the rustling sound of Guan Ming's pen falling on the paper.

With Jiang Yixing's diagram and the first few steps as a base, Guan Ming solved the problem in only 3 minutes.He transcribed the answer into a book, and flipped through the reference answers during the process, and the final result was correct.

Seeing Guan Ming close the book, Radar didn't know why he was relieved.He hurried out to smooth things over: "Let's go, let's go to eat."

Guan Ming nodded, lowered his eyes to pack his things, and awkwardly followed the three of them out of the competition room.

It took too long to solve the problem. It was already dusk when the four of them walked out of the teaching building, and the canteen had already turned on the ultraviolet light to start disinfection.Lin Qianshu thought for a while, and said to the three students, "Let's go, I'll invite you to eat outside."

The four of them went to the fried noodle shop at the corner of the school, and one of them ordered a plate of fried noodles for dinner.Lin Qianshu observed Jiang Yixing while eating, and felt that there were too many mysteries about his younger brother.

Jiang Yixing was not unaware of being watched by such a strong gaze.

As the saying goes, only magic can defeat magic.So Jiang Yixing simply put down his chopsticks and looked back at Lin Qianshu with a cold face.

The two people sat in the noodle shop and looked at each other face to face. This scene was so strange that the reflection arc was as long as the radar, and it was abnormal.He cautiously asked the two of them: "Brother Lin, Brother Jiang...do you two have anything to say?"

Lin Qianshu hesitated: "You... Did you pretend that you were not good at math?"

Guan Ming, who had been engrossed in eating noodles, suddenly sneered: "How many junior high school students can use Helen's formula in the second year of junior high school?"

Heron's formula is a formula proposed by the ancient Greek mathematician Helen that can calculate the area of ​​a triangle. It is very powerful and useful, but it is not included in junior high school mathematics textbooks.

Radar touched his head, and asked Jiang Yixing in a low voice: "Brother Jiang, was Helen Keller invented the Helen formula?"

In just one sentence, Jiang Yixing glanced at Da Dao, raised his hand and gave him a slap in the face: "Read more."

After his brain collapsed, Jiang Yixing looked at Guan Ming again, frowning: "You seem to have always had a problem with me, why?"

Hearing Jiang Yixing's question, Radar and Lin Qianshu both ran across the same barrage in their minds: "You finally found out!"

"Why?" Guan Ming frowned, "Don't you know?"

Looking at Jiang Yixing's puzzled eyes, Guan Ming seemed to be able to see what happened a long time ago through him.

"Let's start from the second year of junior high..." Guan Ming said.

It was a lunch break when Guan Ming was still in his second year of junior high school.Before the lunch break, the math teacher distributed the homework for the evening. As a child who loved mathematics since childhood, he couldn't wait to do it as soon as he got the paper.He did it very quickly, and went from the first question to the last one without any delay.However, it was the last question that stopped him, and he couldn't get the answer after thinking hard for a long time.

It was a complex geometry problem to find the area of ​​a triangle. When Guan Ming closed his eyes, he could feel countless triangles circling around him.

It was a sweltering afternoon, and the other students in the classroom were lying on the table and fast asleep. The cicadas outside the window were mixed with the noise of the ceiling fan on the top of the classroom. The irritability of not being able to figure out the answer was infinitely amplified by the sound, and the official chirped. I can only stand up and go outside to get some air.

When he walked to the door, Guan Ming glanced at the seat by the door inadvertently, and couldn't help but stagnate in his steps forward.

——He saw that on the seat by the window, the pen tip of the prostrate teenager stopped next to the question that he couldn't think of.In the young man's hand was a draft that had only been typed for a few pages. On the draft paper was written a series of formulas that Guan Ming had never seen before. A number was written under the formula, and a circle was drawn on the outside with a pen.

The boy lying on his stomach was Jiang Yixing, a student whom Guan Ming had previously thought had to take a detour.But at this moment, Jiang Yixing fell asleep peacefully on his desk, and it didn't look as scary as the rumors said.

By coincidence, Guan Ming memorized the formula written by the young man on the draft.He quietly turned around and returned to his seat, trying to use this formula into the title for calculation.

A few minutes later, seeing the same answer as Jiang Yixing obtained after a page full of calculations, a complex emotion rose slowly from the bottom of Guan Ming's heart.

In the evening, Guan Ming went home and consulted his tutor. The tutor told him that it was an area formula that did not belong in the textbook, but it was easy to use beyond the outline.

"Who told you this formula?" the tutor asked Guan Ming with interest.

The back of the young Qingjun appeared in Guan Ming's mind for no reason.He said vaguely, "A classmate."

"Oh, then your classmate must be very good at mathematics." The tutor said.

Not at all.Guan Ming thought that every time the math teacher praised Jiang Yixing, he was not on the list, and he probably only got very mediocre marks.

Guan Ming was the only one in the class who got that question right that day. The next day when the math teacher praised Guan Ming vigorously in the classroom, he couldn't help but look back at Jiang Yixing.

Jiang Yixing was looking at a sparrow falling in the corridor with his chin resting on the window, and he didn't care about the math teacher losing his temper on the podium.

Guan Ming looked at his back and felt a slight ripple in his heart.

What is he thinking?Guan Ming didn't know.

From that day on, Guan Ming involuntarily began to care about Jiang Yixing's every move, and he attributed this concern to the joy of finding a fellow student in mathematics.He wanted to happily discuss the three methods of solving the area of ​​a triangle with Jiang Yixing.

However, Jiang Yixing still maintains the style of a school bully who comes and goes like the wind. Although he has not seen him fighting in the school, he will get some scars on his body every now and then, and he is cold and difficult to approach. Everyone in the school rumors that he fights every day After school, I asked a group of vocational high school students to fight for [-] rounds in the garden behind the school until the sky was dark and the sun and moon were dark.

The wisdom of writing Helen's formula that day was like a flash in the pan, and even Guan Ming himself began to wonder if Helen had solved the problem for him in a dream.

So during the lunch break that day, Guan Ming repeated the old trick, and once again saw the correct answer to the solitary finale question on Jiang Yixing's draft paper.If there is one, there will be two, and he ran into many times one after another.

——Jiang Yixing seems to have a grudge against the math practice papers. He knows how to do all the questions, but he has to selectively correct a few wrong answers.

This person, who is obviously very good at mathematics, has a bad taste in controlling his scores to a mediocre level.

As a teenager who loves mathematics, Guan Ming is deeply angry because of Jiang Yixing's attitude of playing with mathematics.

This kind of anger reached its peak after Jiang Yizhi went to their school to hold a report meeting for elite students—the elder brother is such an excellent math student, why is the younger brother such an arrogant bastard?

After that day, Guan Ming unilaterally declared that he and Jiang Yixing had become enemies.

Until today.

Listening to Guan Ming's intermittent recounting of his memoirs, Radar's expression has changed from an old subway man looking at his mobile phone to staring at his eyes and mouth wide open, with "Who am I where am I and what am I going to do" written all over his face.

"That's it." Guan Ming exhaled slowly, and glared at Jiang Yixing again.

Jiang Yixing was able to maintain a blank expression at first, but the more he listened to the expression on his face, the weirder it became. After hearing Guan Ming's rumor that he was fighting with the vocational high school every day after school, the corners of his mouth couldn't help twitching a few times.

"Who told you that my injuries were caused by a fight?" Jiang Yixing asked.

Guan Ming: "That's what they say in school."

Jiang Yixing said blankly: "Oh, the school made a mistake."

"At that time," Jiang Yixing's complexion gradually turned ugly, and he struggled to find the answer, "I just started to learn to skateboard."

"Huh?" Guan Ming couldn't help but widen his eyes, "Did you fall when you were learning to skateboard?"

Jiang Yixing turned his head: "Isn't it normal to learn to bump and bump at the beginning?"

The person involved is a lone ranger, so naturally no one would dare to spread rumors to him.So this rumor existed by mistake, and the mystery was not revealed until today, two years later.

Guan Ming took a deep breath, and asked the question he cared about the most: "Then why do you always like to deliberately correct two mistakes when doing math problems?"

Lin Qianshu remembered the wonderful "13.5 people" in the first invigilation exam, and looked at Jiang Yixing with concern.

Jiang Yixing stared at the table, then suddenly picked up his chopsticks and said to the other three people: "The noodles are getting cold, eat quickly."

...What kind of super bad topic change technique is this!

The three were speechless, but the person concerned insisted on refusing to speak, so they could only pick up chopsticks and continue eating noodles.

When he was about to finish eating, Radar's phone rang. He took out his phone and glanced at the screen. Lin Qianshu's eyes were sharp, and he saw that the note on the screen was "Mom".

Radar stared fixedly at the screen, letting the bell sing for a while before it ended automatically.He put away his mobile phone and hid it in his pocket, and continued to eat noodles with chopsticks.

Jiang Yixing took a sip of mineral water and asked him casually, "Whose phone is it?"

Radar paused for a moment with the hand holding the chopsticks, and then replied casually: "No one, just a salesman."

Lin Qianshu, who saw the number note in his eyes, sighed.

So... Lin Qianshu thought, once some wounds are formed, they can't be healed easily by apologizing.

The author has something to say: Xiao Jiang pretends to be a pig and eats a pig.
