Natural black penetrates into infinite flow

Compass routinely patrols the corridors, specially catching those students who don't do well in the questions and like to skip classes.

It floated to Class 10 ([-]) of high school, and saw three people coming out of it.

Xia Mingchi held a note in his hand, "Teacher, I want to ask you a question."

Having been teased by Xia Mingchi's brain teasers before, Da Compass doesn't want to talk to him at present.

"If it's not about math, don't ask, or you'll blow your head off."

Zheng Bin: "It's about functions."

Compass became interested, "Let's hear it?"

"x/sin(x)±y/sin(y)=±xy/sin(xy)."

Xia Mingchi opened the paper and showed the equation on it.

Compass dubiously said, "Aren't you poor in mathematics? How did you know such a complicated function. And... this content is not taken in the college entrance examination. It is a waste of time to delve into it."

Xia Mingchi pointed to Lu Qihuai, "Student Lu wrote it, but we don't know how to draw its graphics. You don't tell us how to draw it, do you think it's too difficult? No way, no way... the teacher who teaches mathematics even functions Can’t even draw pictures?”

"How is it possible!" Compass was enraged.

Xia Mingchi: "Then draw it on the floor with chalk."

Compass looked left and right, "The floor space in the corridor is not enough, go to the platform."

The back-shaped teaching building is connected by a wide platform between the two main buildings.Compass pulled out the chalk from one end, copied Xia Mingchi's equation on the floor, and began to draw the coordinate system.

Xia Mingchi added, "Teacher, please be sure to draw the standard diagram."

Compass said impatiently: "Of course! What we teach mathematics is rigor!"

"Then draw slowly~"

The three boys tiptoed to the stairs and quietly went downstairs.The graph of this equation is staggered like a fishing net, which is enough for a math teacher to draw for a while.

When he first entered the game, Xia Mingchi delivered the Chinese homework, next to the Chinese teacher's office was the math teacher's office.

Lu Qihuai took out a piece of wire from her pocket, turned it twice in the keyhole, and opened the door.

I saw a thick layer of dust on the desk.

The three of them split up and found a dirty whistle in a certain pen container when the door opened at an inopportune time.

scare? !

It's not a compass, it's a pen.

"Chinese teacher?" Xia Mingchi responded quickly.

The pen is inexplicable: "I'm out of ink, what are you doing here?"

Lu Qihuai was very calm: "Help the math teacher find a ruler."

The pen took two steps back vigilantly, "Ruler? There is no class now, why use a ruler?"

"You don't mean to steal the whistle..." The pen suddenly reacted, the cap opened, and the tip of the pen turned into a sharp knife.

"Heh~" Xia Mingchi suddenly laughed.

The pen was puzzled, "What are you laughing at?"

Xia Mingchi walked slowly to the pen, "There are more valuable things in the office, you don't care, just ask if you want to steal the whistle, which proves from the side that our idea of ​​breaking the game is correct."

"Those that follow the dean's wishes... will become objects. You are a pen, the math teacher is a compasses, and now even the students are like workbooks..."

The pen said: "What's wrong with becoming like this? Isn't the college entrance examination just looking at the score?"

Xia Mingchi retorted: "It's a score, but it's not the only one. In high school, there should also be friendships that help each other, vague liking, and teachers who can teach students in accordance with their aptitude. These will not affect students' pursuit of scores, but will make them Their campus life is colorful."

Zheng Bin added: "That's right, students are human beings, not machines."

"Stop talking nonsense! The school's enrollment rate will be affected because of the existence of you aliens. The dean is still too lenient... I won't. But don't worry, I move quickly, and you won't be hurt."

As the pen spoke, it stabbed at Xia Mingchi.

Xia Mingchi picked up a chair to block it, the pen slammed down and nailed, the blade pierced through the sponge pad and the seat board, and got stuck in the middle.Seeing this, Xia Mingchi quickly let go of the chair. Before the pen could bear the force, it fell to the ground together with the chair.

Zheng Bin picked up the hammer he found in the glove box, and hit the pen with a hammer.The pen was smashed, and the side of the blade returned to a normal nib.

On the other side, the dean's office.

The dean, who was leaning on the seat, put down his cup and asked cautiously, "What's the sound?"

Zhou Zheng, who was reading for self-reflection: "Ah? Did you hear me wrong... I still have the last paragraph to finish."

"Stop reading," the dean had a bad feeling, got up and walked to the door.

"No!" Zhou Zheng yelled, "Meng Yijie will also review after I finish my studies... My dad said, you have to take good care of me. If I pass the exam, I will donate money to the school to build a new campus!"

"Oh?" The dean let go of the doorknob, and he sat back again with an arrogant tone, as if he was a merciful and kind person.

"Okay, I'll take the time to talk to you guys today. But let me state in advance that I'm not doing it for the new campus, but to help the students who are lagging behind. You know, I usually don't spend time on students with poor grades. Yes, because they're not worth it."

After school in the afternoon, Zhou Zheng felt his ears buzzing, as if flies were flying.

He and Meng Yijie came out of the dean's office and kept picking their ears with their hands.

Meng Yijie: "What are you doing?"

Zhou Zheng was in pain: "The dean is too long-winded, and Che Jilu talked back and forth. I am really lucky that I didn't meet this kind of teacher in high school..."

After reuniting with Xia Mingchi and the others, Zhou Zheng asked, "Is everything going well?"

Xia Mingchi said: "There was a little accident, but it has been resolved."

On the platforms of the two buildings, the compasses were still drawing, but the chalk was given by Xia Mingchi when he first entered the dungeon, so it didn't take long for it to be used up.

Seeing the students approaching, Compass excitedly jumped up and down in the air, "Although the chalk is gone, this part of the graphics is enough! Come and have a look!"

On the ground is a huge Cartesian coordinate system, on which curves are arranged in a meandering manner.

The use of complex equations is to hold the compasses. What about after taking the whistle?What about compasses?Head-to-head confrontation will lead the dean out in advance, and if it doesn't work out, it will get stuck.

But if left alone, will it hinder the player when confronting the director?

Xia Mingchi gestured to his companions, telling everyone not to act rashly for now.

"Teacher, there is something wrong with your drawing." Xia Mingchi said.

Compasses was very upset, he used up all the chalk for drawing, and the student actually told himself that there was a problem? !

"Tell me what's wrong, or I'll blow your head off!"

The compasses suddenly jumped in front of Xia Mingchi's face, and the wooden handle pressed against the boy's fair and tender cheek, leaving a red mark.

Others watched with horror.

"The function I'm talking about is to draw a complete image, that is, from negative infinity to positive infinity. This range of values ​​is obviously a subset. If you don't review the questions clearly like you during the exam, I'm afraid you won't be able to score the whole question .”

Compassionate was irritated by Xia Mingchi, and said angrily, "I know! But there is not enough chalk!"

"Can't you find a way to overcome it? Your other end is the head of a nail, which can scratch the ground. We only want to learn complex functions to improve our grades, so the dean will definitely not blame the teacher if he knows. If you can’t draw on the platform, you can still go to the playground to draw.”

"After all, you are the only math teacher in our school now. Our math grades are all based on you for improvement. Whether we can go to a prestigious university depends entirely on you!"

Xia Mingchi changed the subject in the second half, and began to shoot the rainbow fart of the compasses.

"That's right... I'll engrave the pattern on the playground for all the students in the school to see!" Compasses happily went downstairs.

With a three-inch tongue, he trapped an NPC in this way.

Zheng Bin sighed: "From negative infinity to positive infinity, I'm afraid I can't finish the nails. Xiao Xia, you are really amazing."

After entering the dungeon, Xia Mingchi obviously felt that Compass agrees with the teaching director's teaching ideas and is sensitive to scores and exercises.It is simply beneficial to this characteristic and leverages strength.

Lu Qihuai said: "Now, there is only one target left."

As night fell, Yang Jinshu rushed over with Wang Keran and Sun Rui.

Everyone went to the dean's office together, but the door was locked and no one was there.

Yang Jinshu said: "Usually at this time, the dean will wander around the campus."

"Then it will be hard to meet," Zhou Zheng said, "Why don't we just blow the whistle to lure him out?"

As soon as he finished speaking, he saw a thick-haired, short and fat middle-aged man slowly appearing from a dark shadow in the distance.

"Ah!" Wang Keran recognized the person and shouted in a low voice.

Even though she was dead, the dean's verbal violence left a deep shadow on her, and she trembled while holding Yang Jinshu's hand.

Yang Jinshu and Sun Rui stood behind Wang Keran together, no matter whether it was life or death, they had to protect their friends.

The teaching director smiled, like a good-tempered uncle in life, but his mouth was like a knife.

"Sun Rui, you really don't have a long memory, and you still miss Wang Keran after you die. Yang Jinshu, you also let her play a trick? I really don't understand, just such a little bitch who smears the school and drags down the students, you Why are you so guarded?"

"Do you really expect to be admitted to the same university with Wang Keran's grades? Obediently listen to the teacher. Poor students are losers and scum. From now on, you are people of different levels. Don't hang out with her."

Tears flowed down Wang Keran's eyes. Before her life really started, she was judged by her respected teacher-bad student, loser, and scum.

She just has poor grades, and she just wants to learn from students with good grades, but in a school where students are divided into grades based on grades, it is really too difficult to stand up.

Yang Jinshu was trembling with anger: "Shut up, you! I only make friends based on whether I like her, and it has nothing to do with her grades!"

Sun Rui also sharply refuted: "Life is a long-distance race, who said that after poor grades in high school, you must not be able to do it?!"

"I know that you have been brainwashed by this little bitch. From now on, you are no longer my students. Don't spoil the younger students."

The dean walked slowly towards Xia Mingchi and the others. When he approached, Wang Keran retreated habitually.

"Son, I found out that the math teacher is still drawing function diagrams on the playground. It's too miserable. There is no chalk, so I use my hands to scratch and draw with blood... I can't stop... What are you doing?"

Xia Mingchi blinked his innocent eyes: "It's nothing, just study hard and ask questions."

The dean patted his hands lightly twice, and all the exercise books that had been sitting in the classroom brushing questions flew out.

These notebooks were in groups, like big moths, constantly flying and floating in the air, gathering behind the dean.

"It's not a good student to lie to the teacher..." Before he finished speaking, Xia Mingchi rushed out like an arrow from the string, grabbing the dean's hair!

When everyone reacted again, he had already returned to his companion, with black hair on his hands.

And the dean showed his bald head.

Xia Mingchi: "Oh my god, he's really bald..."

Zheng Bin despaired: "What are you doing?!!"

Angry NPC to pull hatred?

"If you scold Wang Keran in public, do students with poor grades have no self-esteem? So I have to let the teacher experience the feeling of losing dignity." Xia Mingchi spoke eloquently.

"Pfft!" Lu Qihuai lightly pressed her right hand to her lips, and smiled dotingly.

The dean showed a sullen look on his face, and the wind kept coming.Xia Mingchi took out his whistle and blew it hard.

"call out--!"

The piercing whistle was like a sharp blade cutting through the sky.

"Damn it!" The dean scolded angrily, and the exercise book behind him was like a dart, slashing at Xia Mingchi and the others.

"Hoo-!"

"Ahhhhhhh! It's so loud!!" The dean covered his ears, twisting his fat body like a maggot.

The whistle obviously suppressed him, and the number of practice books flying in the air decreased significantly after the whistle sounded.

Wang Keran's hair suddenly grew long and entangled the dean.Sun Rui tore off his diary, and every time he tore a page, the paper would automatically turn into an arrow, nailing the exercise book to the ground.

Zhou Zheng and Lu Qihuai were on both sides of Xia Mingchi, as if they were guarding the Dharma on the left and right, and shook off the flying books with their school uniform tops.

Meng Yijie rushed to the front. She didn't know where to find the utility knife, and directly stabbed the dean with a knife.

The dean screamed in pain, kicked Meng Yijie with his thick legs.

Meng Yijie didn't say a word, her expression was pained, but she didn't stop her hands.

The dean's body became mushy as the whistle intensified, and finally turned into a brick-thick book with a long whistle.

Booklets flying in the air fell to the ground like dead birds.

A ball of light floated out of the body of the teaching director. Everyone watched quietly, not knowing what would happen next.

Although Xia Mingchi was protected, he was out of breath from blowing whistles one after another. At this moment, he only felt that his eyes were dark and the soles of his feet were weak.

Lung capacity needs to be practiced well.

Lu Qihuai hugged him considerately, let him lean on her chest, and held his slender waist with her hands.

"Are you okay?" Lu Qihuai asked softly.

"Yeah." Xia Mingchi wiped off his sweat, squinted his eyes to identify the light ball, "That's it?"

"Reward items for customs clearance!" Zheng Bin burst out suddenly.

Xia Mingchi only found out that Zheng Bin hadn't been seen at the moment of the final decisive battle just now, so it turned out that he had been sneaking behind him all the time.

wrong.

The rewards obtained before were given by the guide after the dungeon.

If they have passed the level, why are they still in the dungeon at this moment...

Zheng Bin danced excitedly, "Great! I have passed so many levels, and finally one level will drop a reward! And it looks very advanced!"

Like a wolf snatching food, he staggered forward, and when he pushed Meng Yijie away, he glared fiercely at her.

You can't find anyone to fight against the BOSS, and you can run faster than anyone else when you drop things.

Meng Yijie had a premonition of danger, so she staggered to her feet and ran towards Xia Mingchi.

"Don't..." Xia Mingchi wanted to stop Zheng Bin, but it was too late.

Meng Yijie's prediction was correct. When Zheng Bin reached out to touch the light ball, the light ball suddenly passed through his body and exploded.

At the moment of the explosion, a barrier suddenly popped out from Xia Mingchi's pocket, covering him in front of him, blocking the aftermath of the violently shaking air.

The barrier simultaneously protected Zhou Zheng, Lu Qihuai and Meng Yijie.

It was Louis' royal blue cufflinks.

The ball of light blasted Zheng Bin into two pieces, his upper body fell heavily in front of everyone, and the lower part of his waist flew through the air and fell downstairs.

Lu Qihuai hurriedly covered Xia Mingchi's eyes with her hands, preventing him from seeing such a bloody scene.

Zheng Bin tried his best to raise his neck, his mouth widened in surprise, and his eyes were terrified and surprised.

"Help……"

Then, the sky and the earth began to shake violently, and Xia Mingchi felt that his body was falling.Before he fell into a coma, he heard Lu Qihuai whispering in his ear.

"Great, you passed another level."
