Demon Development System

In front of the city's first school, Li Zheng was righteous and talked about it, and cleaned up the situation that day.

"...That was the day, and finally spent a pleasant night with Zhang Xiaoke's mother."

After talking, Li Zheng remained motionless, at least he didn't see any confusion on the surface.

But Shi Yang next to him had already started to breathe.

Brother I know I was wrong.

But you don’t have to do it yourself!

Shi Yang turned to look at Lin Yuejing and was ready to sneak away.

However, Lin Yuejing snorted mercilessly: "It's boring, I went to the exam room."

Then, happily jumping away.

Shi Yang couldn't understand it anymore, so Li Zheng asked, "Is this all right?"

"Do you still have a face to ask?" Li Zheng turned around angrily. "I will never guide you in EQ classes anymore, just hit the wall yourself."

"Don't~~" Shi Yang hurriedly chased up and asked Li Zheng's arm, "Anyway, you two must be a boyfriend and girlfriend, right? I won't be wrong this time."

"Sorry, you are wrong again."

"Ah?" Shi Yang thought, "If it's not a boyfriend or a boyfriend, why do you desperately explain what to do and what's with her?"

Li Zheng pondered for a moment, then suddenly glared, "Yeah, what do I explain?"

"Hey, could it be that kind of boyfriend who hasn't made it public yet?" Shi Yang rubbed his hands and asked, "So the girl's tongue..."

"Shut up!" Li Zheng shouted away from Shi Yang, "I don't know the girl's tongue, your tongue is really dangerous!"

"Ah, ah, no more, no more." Shi Yang turned out the admission ticket and said, "I 2 exam rooms, how about you?"

"..."

"Huh? Won't it be so coincident?"

"leave me alone……"

"Don't introduce, isn't it good that our brother swept the exam room and installed a beep?

"No, go!"

After all, it was Shi Yang’s school. He could be regarded as a familiar driver. Between the two of them shoving all the way, he quickly reached the examination room No. 2.

The semi-finals did not compare to the preliminaries. Li Zheng responded seriously and entered the classroom 15 minutes ahead of schedule.

However, from this point of view alone, everyone in the examination room is actually more serious than him, and it's all over soon.

This also saves them from finding a seat. Li Zheng and Shi Yang soon take a seat, one left and one right, with only one person in between.

After setting up the stationery and calculator, Li Zheng of course looked to Shi Yang.

Shi Yang had already set it up naturally, and was looking at himself with one leg bent and rubbing his ankle.

Looking at the one in the middle, he looked down at a blue book without moving.

The words printed on the cover are simple and clear, just two words—

"Mechanics".

This is the foundation of a university physics textbook and the foundation of the physics competition theory book.

Li Zheng has seen it for a long time.

This is 10 minutes away from the rematch. You have to look at electromagnetism or something. It is justified to strengthen the formulas and rules. Looking at the mechanics textbook is really ridiculous.

It's like a gymnast is about to jump on the field, temporarily looking at the technical specifications from the beginning.

Looking at this person again, his hair is slightly longer and his face is half-blocked, and he can only be determined to be a boy from the shirt and sneaker styles.

In short, it seems that learning is very bad.

Still a hairy monster.

I don't know which school, this kind of hairstyle will not be done by the director.

Li Zheng then swept to the long-haired monster's desktop, nothing, just a pen.

Calculator, physics rematch, how can you not use a calculator?

Thinking of this, Li Zheng couldn't help but think of himself in the chemistry preliminary.

At that time, he didn't bring the right calculator, he was kindly reminded by Wu Shu, and then she and Ou Xingzhuo got a good job.

This scene is somewhat similar to that time, except that the friend who was temporarily holding the Buddha's feet was caught in the middle.

When Li Zheng was thinking about not reminding him of the calculator, Shi Yang couldn't help but started to install it.

"Hey, think about it. I'm quite full," Shi Yang said, patting his thigh. "I'll be ICho next month. I won't have time to go even if I reach the finals."

People around can't help but look around.

This beep is too stiff, and no one was shocked, but simply wanted to see which fool made a rant.

But after all, there will be a few people who know the goods.

"Ah!" a boy exclaimed, "Jijing does have an ICho player... is it you?"

"Oh." Shi Yang smiled and greeted him, "Brother knows how."

"So you are... Cobalt God? Shi Yang?"

Shi Yang beautifully wrote: "It's just down."

"Fuck, how come you are competing?"

"Hey, just play around and gather a dragon ball." Shi Yang said, "I didn't review it, so I just entered the rematch, and the intensity of the competition is not good."

"By...the cattle are the cattle..."

"Kneeled for Cobalt God."

"Then if you enter the experimental competition, will you have time to go?"

Studying the mainland, with respect for grades.

No matter how stupid you are, as long as you study well enough to be able to enter ICho, you will be held by the stars.

Shi Yang already had no beep to install in the school. In this environment, it can be regarded as a fish, and he immediately pointed to the mountains and rivers, indicating that ICho has everything in his pockets.

He brags, this is not enough.

You have to make your brother cool.

"Now!" Shi Yang raised her hand and pointed at Li Zheng. "Oh, don't you know who he is?"

"Who is it?" the people around asked quickly.

"Ha, Li Zheng, Meishen, have you ever heard?"

"I know that Huajing is the first in the country."

"Good!" Shi Yang laughed, "This forced chemical strength is not below me, and the physical strength must be above me. This time, Sakura Lake Shuangsha is competing in the competition, you have to be careful."

"Look at this..." the other boy was startled, "I seem to have seen Li Zheng's video...at a party."

"Brothers have good eyesight," Shi Yang praised. "After all, they are beautiful gods.

"I rely on, our exam room is really good!"

"The Great God less stimulates us, can't bear it..."

"Big Brother, please slow down. Don't scare us."

Between the praises of your words, the atmosphere in the classroom becomes warmer, just like the nonsense in the Jianghu Tavern.

Li Zheng was surrounded by surrounding people in the middle, and just waved his hands and smiled, and had nothing to say.

Although the beep is wrong.

But being blown around by everyone.

It's actually quite cool.

I think Li Zheng has been mixed for the past six months, and it is also a No. 1 character. It is a little refreshing, and I have said it in the past.

However, the long-haired monster next to him who looked down at "Mechanics" didn't even raise his head.

Even the pages of the book have not been turned.

Li Zheng thought of Wu Shu's kindness, he coughed and raised his hand to shake the calculator.

"Do you not have a calculator, friend?"

The man still lowered his head and ignored him.

Li Zheng waited for more than half a minute and did not respond, so he shook his head with a smile.

Forget it, let's not be a good teacher, just play your own.

Soon, the three invigilator teachers entered the room, and the students also received their voices, and handed over the review materials and mobile phones.

The long-haired monster next to him remained still, and the book was still on that page.

Shi Yang couldn't see it, and stepped forward to take a picture: "Brother, don't watch it, it's too late."

The man was motionless.

Waiting for a while, a proctor who has a temperament similar to Sun Xiubin also felt that something was not right, and walked over quickly.

Halfway through, the long-haired monster suddenly raised his head suddenly, sucking a big breath with glaring eyes.

Then, staring at the spot and panting.

Everyone around was taken aback.

The invigilator teacher, "Low Version Sun Xiubin" was frightened to stop the pace: "Classmates, do you need help?"

"No... nothing..." The hairy monster panted and shook his head.

This voice is immature and weak, in fact, it is not like a boy.

It was only at this time that Li Zheng saw that he was not even a boy, he was too white and delicate, his face was slender, but his eyes were very big and watery, and his eyes were full of innocent eyes.

Not only like girls, but also like children...

Sure enough, he is a guy who knows nothing.

Shi Yang on the other side also looked at it for a long time, shyly looking at it.

He was not afraid of dealing with boys, but when he saw such a beautiful and young boy, he was also panicked.

At this point, "Sun Xiubin" had come to the long-haired monster and asked with concern: "Is it really okay? It looks bad on you."

"Ah... it should be..." The hairy monster is also eloquent, and wiped his mouth in a hurry, gradually speaking incoherently, "Even if it's okay...um...should be..."

This kind of shyness and transient aphasia, Li Zheng sees a lot and knows the situation well.

"Did you fall asleep and have a nightmare?" Li Zheng asked with a smile.

"Ah... yes, I have a nightmare..." The hairy monster responded quickly, glanced at Li Zheng gratefully, and then grabbed the book and held the table to get up. "Sleep too long... Is it time to hand in the book?" Time?"

Everyone around laughed, and there was no malice.

It's amazing that such a large group of people can enter the semi-finals.

"Hey..." "Sun Xiubin" reluctantly pointed to the cabinet in the back row of the classroom. "Those things that are not related to the exam should be put there."

"Um, sorry teacher..."

"Sun Xiubin" said seriously: "You don't have to be sorry for me, not for my exam, but I also hope you can correct your attitude and be worthy of yourself."

"..." The long-haired monster turned red and happened to hit Li Zheng's smiling face. He also spit out his tongue and smiled, so he quickly walked towards the back of the classroom.

"Sun Xiubin" shook his head helplessly, and then returned to the blackboard, writing the exam notes and time schedule on the blackboard one by one.

The long-haired monster quickly returned to sit firmly. After the catastrophe, he usually wiped his sweat and blocked his face and smirked at Li Zheng, "Thank you."

"Not talking." Li Zheng waved his hand and smiled.

Unexpectedly, this hairy monster is still very good at dealing.

It's a bit too casual. I didn't read through the basic textbooks. I didn't bring a calculator. I was dozing off.

But conversely speaking, it is also a talented person who can enter the semi-finals at will.

Li Zheng picked up the calculator and shook it: "The amount of calculation in the semi-finals is large, so you should bring a calculator."

"Ah, is it?"

"Well, it can save a lot of time." Li Zhengchong pouted, "If you're embarrassed, I'll raise your hand and say, there should be several spare calculators for each test room."

The long-haired monster waved his hands again and again, his face flushed again: "It's okay...it's not necessary..."

"The exam is very important, why are you shy?" Li Zheng leaned forward and handed over his calculator. "You use mine, I'll ask for it."

"Don't!" The long-haired monster rubbed the table to the side, scared, "I really don't need to... I'm good enough for my mental calculations."

"Huh?" Li Zheng laughed, "This is a physical competition rematch, mental arithmetic?"

"It's okay, I'm pretty quick." The long-haired monster scratched his head and pushed Li Zheng's hand. "Thank you."

"Hey." Li Zheng also had to shake his head and withdraw the calculator, "Look at your appearance, it should be a high school one? It doesn't matter if you fail this time, learn a lesson, remember to prepare well next year."

The long-haired monster was dumbfounded for a moment, then concealed his face and nodded stupidly: "Good, I know."

"Rely on..." Li Zheng was uncomfortable. "Can you stop it with "..."?"

The hairy monster turned his head and asked in a silly manner: "What's wrong?"

"Forget it...just be happy..."

"Then forget it." The hairy monster laughed again.

"It's enough……"

The voice of "Sun Xiubin" suddenly came: "You two haven't talked enough yet?"

The two quickly picked up and closed.

Sun Xiubin just lighted the blackboard and said: "Finally reiterate again, the examination time is 9 to 12 o'clock, the total score is 320 points, when the end bell rings, whoever writes another word will be treated as a violation."

Everyone was staring and listening, not daring to speak.

After everything is arranged, the bell rings and the test is issued.

Li Zheng is also a battle-tested field. After getting the paper, he no longer feels as surging as before.

There is only one word all over him—

stable.

Don't think about things like grades.

If possible, try not to think about Lin Yuejing's answering situation, which is difficult and can only be tried.

Just like doing the usual questions, it's right to dry one by one like water.

Li Zheng swept away from the first question.

It is indeed a rematch, the difficulty of the first question will rise.

It's about a small round table on a station wagon.

The bottom of the small round table is supported by three poles, like a camera tripod.

Then there is a cup of tea right in the middle of the table.

Ask how much tea should be as stable as possible, and how high should it be best.

This is a very common process in life, probably about it.

But if we discuss from a physical point of view, it is a long and complicated calculation process.

In the simplest terms, it is to keep the center of gravity of the glass as low as possible.

After determining this goal.

This question has nothing to do with physics.

Transferred to the field of analytical geometry and calculus.

Put another limit.

Simultaneously formulate the equation.

Remove the negative solution.

Now, does this answer come out at random?

h=m/ρπ2[{(1+4π/5·ρr2H/m)^1/2}-1]

It's concise and clear, basically no calculations, purely hot hands.

The second question, the villain cart.

It's just that this time it's an agricultural flatbed, with two wheels and two poles and one big flatbed.

It's time to calculate and calculus again.

There are also some simple torque, rigid body mechanics, and energy conservation issues.

Just pay a little attention to a bunch of two-dimensional collision problems.

After breaking these apart.

What remains in front of me is still a mathematical geometry problem.

The name of the physical competition is well-deserved, and it really is a calculus competition for middle school students.

After Li Zheng wrote an extremely long answer, he immediately looked to the side table.

The long-haired monster is staring at the roll in a daze, both eyes stunned.

Hey, you are still too young.

Go home and learn calculus again.
