At this time, Han Jing, who came with her, glanced at Su Yun and defended him: "Classmate Su Yun is very honest and respectful of his teacher, it is impossible to do such a thing." ”

He Haiyin and Yang said angrily: "Teacher Han, do you think I slandered him?"

Han Jing said with a serious face: "Teacher He, you are too worried, I didn't mean that, I think it is better to find out the cause of the matter and the process." ”

Su Yun glanced at Han Jing gratefully, then raised his head and asked, "Teacher He, you said that the injuries on your body were caused by me, do you have any evidence?"

He pointed to a long old wound on his arm and said, "If you can slander it without evidence, then I can also say that you caused the wound." ”

"You"

He Hai's face turned red with anger, and the vice principal also glanced at He Hai when he heard this, and asked, "What your students said is reasonable, you said that you were beaten by students, are you in the classroom? Can the students here testify?"

Han Jing asked a student gently, "Classmate, did you just see your homeroom teacher being beaten by classmate Su Yun in the classroom just now?"

The student shook his head and replied honestly, "Teacher Han, we didn't see Head Teacher He being beaten by Su Yun, he fell by himself, and he fell twice. ”

When the student finished speaking, the class burst into laughter again.

Su Yun sneered and said, "Head Teacher He, I can't imagine that you invited the principal here to see that I didn't like me, so you deliberately fell down twice and slandered me and beat you, and then let the principal expel me?"

He snorted angrily, his volume increased by two sections, mixed with the soul power of the Cangyun Immortal Emperor, and said angrily: "Do you think that the school is run by your family? You can expel whoever you want? Do you think the principal is so easy to fool? Let you drive?"

Su Yun's voice was very loud and terrifying, and when He Hai heard this, he looked at the vice principal with an unkind look on him, and his old face turned pale.

He anxiously explained: "No, no, you listen to me, vice principal." ”

The vice principal snorted angrily and said, "Teacher He, you don't have to explain to me, don't let me know your small actions in private, I warn you, I don't care about this time, if you dare to do this next time, I will suspend you." ”

He Hai continued to sweat coldly on his forehead, and almost collapsed to the ground.

The vice principal glanced at Su Yun deeply, didn't speak, and turned around and walked out.

Han Jing gave Su Yun a comforting and warm smile, meaning to tell him that you don't have to worry about me with me.

Su Yun was quite grateful, although he had cultivated the wisdom of immortals for three hundred years, he could deal with this matter without any force, but Han Jing was kind, and he had to take it.

Looking at He Hai's pig liver face, Su Yun smiled and said, "Teacher He, your face doesn't seem to be right, is there some incurable disease, do you want to go back to recuperate and recuperate, go to the hospital for examination or something?"

He Hai said angrily: "Su Yun, don't think that I won't be able to cure you if you play a little trick, from now on, you will go out to listen to all my classes." ”

Su Yun shrugged his shoulders and said, "What if I don't agree." ”

He Haiqi was angry, and said in that sharp voice: "If you don't go out, I won't teach this math, and I will take the college entrance examination now, and the results of the entire third and sixth classes of high school will be delayed because of you alone, and you will do it yourself." ”

Su Yun smiled and said, "Dead bald, are you threatening me with the future of the whole class?"

He Hai's nostrils rose and said, "I'm just threatening you, what do you do with me?"

"People like you are not worthy of being a teacher, and you don't have to go to class for a scumbag. ”

Su Yun walked straight in front of He Hai, his dark eyes were like a cold long knife, and he said loudly: "Besides, I don't think you scumbag can teach me anything." ”

All again stunned, belittled, nakedly degraded!

Su Yun didn't take He Hai, the head teacher, in his eyes at all.

Now that He Hai has been trampled under his feet, Su Yun is considered to have taken a bad breath, in the previous life, he has been trampled under the feet of the other party, sarcastic, despised and mocked!

Feng Shui takes turns, in this life he is an immortal, not afraid of anything!

He Hai was frightened by Su Yun's cold gaze, and he shrank his neck, and saw Su Yun walking to the door, so he said mockingly: "A scumbag is a scumbag, you will never be able to learn the subject of mathematics, you are destined to fail in the college entrance examination, I advise you to go home and farm quickly!"

Su Yun's footsteps paused slightly, and he turned to look at this bald head teacher with a big belly!

He walked up to the blackboard, squeezed He Hai aside, and took chalk to write a line on the blackboard.

Goldbach conjecture!!

Su Yun looked at He Shan mockingly and asked, "Do you know what this is?"

He Hai frowned and said proudly: "I am a mathematics teacher, of course I know this conjecture, it is an unsolved problem in the mathematics world, and it is regarded as one of the three major unsolved problems in mathematics in the world." Why, you want to discuss this with me?"

"Discussion?heh, you're not qualified!"

Su Yun said sarcastically with disdain: "You don't want to see which onion you are, and you want to challenge this conjecture?"

The Goldbach conjecture is an unattainable jewel in the crown of mathematics.

Goldbach conjecture that every even number greater than or equal to 6 can be expressed as the sum of two odd primes, and every odd number greater than or equal to 9 can be expressed as the sum of three odd primes.

Although it sounds simple, it is not easy to get it right, and it took all genius mathematicians nearly 300 years to prove it without success.

According to Su Yun's knowledge, in 1920, the Norwegian mathematician Bujue used an ancient screening method to prove that every even number larger than it could be expressed as (99). This method of narrowing the encirclement has worked.

Scientists then began with (919) and gradually reduced the number of prime factors contained in each number until finally each number was a prime number, thus proving "Goldbach".

In 1924, the mathematician Rade Mahal proved (7+7).

In 1932, the mathematician Eiseman proved (6+6).

In 1938, the mathematician Buchstab proved (5 x 5), and in 1940 he proved (4 + 4);

In 1958, the Chinese mathematician Wang Yuan proved (213).

Subsequently, the young mathematician Chen Jingrun also devoted himself to the study of Goldbach's conjecture, after 10 years of hard work.

Finally, a major breakthrough was made on the basis of previous research, and it was the first to prove (l 102).

At this point, Goldbach conjecture is left with only one last step (1+1).

In late March 1996, when Chen Jingrun was about to take off the pearl in the crown of mathematics, he was only a stone's throw away from the glorious peak of Goldbach's conjecture (1+1), but he collapsed due to physical exhaustion, which is the biggest regret in the mathematical world!

At this moment, He Hai in the classroom glanced at Su Yun with contempt and said, "What's the matter, I'm not qualified, is it true that you, a scumbag who has always scored no more than forty points in mathematics, are you qualified?"
