In front of the No. 1 school in the city, Li Zheng was upright and talked eloquently, taking stock of the situation that day from beginning to end.

“...... That day was like this, and finally spent a pleasant night with Zhang Xiaoke's mother. ”

After finishing speaking, Li Zheng still didn't move, at least on the surface, he couldn't see the slightest panic.

But Shi Yang next to him had already begun to gasp.

Bro, I know I was wrong.

But you don't have to be so self-defeating!

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

However, Lin Yujing only snorted ruthlessly: "It's so boring, I'm going to the exam room." ”

Then, happily jumped and left.

Shi Yang couldn't understand it at all, so he grabbed Li Zheng and asked, "Is this okay?"

"Do you still have the face to ask?" Li Zheng turned around angrily, "I won't guide you in emotional intelligence classes anymore, let's hit the wall by myself." ”

"Don't~~" Shi Yang hurriedly chased after him, arched Li Zheng's arm and asked, "Anyway, you two must be boyfriend and girlfriend, right? ”

"Sorry, you're wrong again. ”

"Huh?" Shi Yang pondered, "If it's not a boyfriend or girlfriend, you are so desperate to explain what you do, what does it matter to her?"

Li Zheng pondered for a moment when he heard this, and suddenly glared, "Yes, what do I explain?"

"Hehe, is it the kind of boyfriend and girlfriend who hasn't been made public yet?" Shi Yang rubbed his hands and asked, "So the girl's tongue ......"

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

"Alas, alas, don't say it, don't say it. Shi Yang flipped out the admission ticket and said, "I'm in the 2nd exam room, what about you?"

“......”

"Huh, it can't be such a coincidence, right?"

"Stay away from me......"

"Don't mind, isn't it just right for our brothers to sweep the exam room and pretend to beep?"

"Don't pretend, get out!"

After all, it was Shi Yang's school, and he was familiar with the road, and the two of them pushed and shoved all the way, and soon arrived at the No. 2 examination room.

The semi-finals were no better than the preliminaries, and Li Zheng dealt with them seriously, and entered the classroom 15 minutes early.

However, from this point alone, everyone in the examination room is actually more serious than him, and they have all arrived at this time.

This also saved them from finding seats, Li Zheng and Shi Yang quickly took their seats, one left and one right, and there was only one person in between.

After setting up the stationery and calculators, Li Zheng of course looked at Shi Yang's side.

Shi Yang naturally had already set it up, and he was cross-legged, rubbing his ankle and looking at himself with a grin.

The one in the middle of the interval was looking down at a blue book without moving.

The words printed on the cover of the book are simple and clear, just two words-

Mechanics.

This is a college physics textbook, the foundation of the theory book of physics competitions.

Li Zheng has naturally seen it a long time ago.

It's only 10 minutes before the semi-finals, and if you want to watch an electromagnetism or something, it's reasonable to strengthen formulas and rules, and it's really ridiculous to look at mechanics textbooks.

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

Looking at this person again, his hair is slightly long, half-covering his face, and he can only be roughly identified as a boy from the shirt and sneaker style.

In short, it looks like a very bad learner.

Still a hairy monster.

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

Li Zheng then swept to the desktop of the long-haired monster again, and there was nothing, just a pen.

Calculators, physics rematches, how can you not use calculators?

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

At that time, I didn't bring the right calculator, and I was kindly reminded by Wu Shu, and then I was sandwiched between her and Ou Xingzhuo.

The scene was somewhat similar to that time, except that it was this temporary friend who was caught in the middle.

When Li Zheng was thinking about whether to remind him of the calculator, Shi Yang couldn't help it at first and began to pretend.

"Hey, think I'm pretty well fed. Shi Yang patted his thigh and nagged, "It's ICho next month, even if I enter the finals, I don't have time to go." ”

The people around couldn't help but look sideways.

The beep was so blunt that no one was shocked, just to see which fool was uttering the wild words.

But after all, there will still be a few knowledgeable people.

"Ahhh......h Is that you?"

"Huh. Shi Yang smiled and raised his hand to say hello, "Brother knows how to do it." ”

"So you're ...... Cobalt God?Shi Yang?"

Shi Yang was satisfied: "It's exactly below." ”

"Holy shit, why did you come to the competition?"

"Hey, just have fun and collect a Dragon Ball. Shi Yang pursed his lips and said, "I didn't review, I just entered the semi-finals so casually, and the strength of this competition is not good." ”

"Damn...... A cow man is a cow man......"

"Kneel to the Cobalt God. ”

"Then if you enter the experimental competition, do you still have time?"

Study the mainland, grades are respected.

No matter how stupid you are, as long as you study well enough to get into ICho, you will be praised by the stars.

Shi Yang has long been out of beeps in school, and in this environment, he can be regarded as a fish in water, and immediately pointed out the country, indicating that ICho has all kinds of things in his bag.

He blew it up, and that wasn't enough.

I have to make my brother cool.

"Na!" Shi Yang raised his hand and pointed at Li Zheng, "Heh, you still don't know who he is, right?"

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

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

"I know that the competition is the first in the country. ”

"That's good!" Shi Yang laughed, "The chemical strength of this force is not below me, and the physical strength must be above me, this time the Sakura Lake Shuangsha will participate in the competition, you should be careful." ”

"Look at it this way...... another boy exclaimed, "I seem to have seen Li Zheng's video...... At a party. ”

"Brother has good eyesight. Shi Yang praised, "After all, he is a god of beauty, and he is proficient in piano, chess, calligraphy and painting." ”

"Damn, our exam room is really good!"

"The great god stimulates us less, and we can't bear it......"

"Brother Zheng, please slow down, don't scare us. ”

Between your words and my words, the atmosphere in the classroom became more and more enthusiastic, as warm as nonsense in a tavern.

Li Zheng was surrounded by the people around him politely, and he just waved his hand and smiled, and he didn't have anything to say.

Although the beep is not right.

But it was blown around by everyone.

It's actually pretty cool.

I think I, Li Zheng, have been mixed up for more than half a year, and I can be regarded as the number one person, and I am a little cool, and I have said it in the past.

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

I haven't even turned the page.

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

"Don't you have a calculator, friend?"

The man kept his head down and ignored him.

Li Zheng waited for more than half a minute and didn't respond, so he had to smile and shake his head.

Forget it, don't be a good teacher, play your own.

Soon, the three invigilators entered, and the students also closed their voices, and handed over the review materials in their hands, mobile phones and other things.

The hairy monster next to him still didn't move, and the book was still on that page.

Shi Yang couldn't look at it, so he stepped forward and patted it: "Brother, don't look at it, it's too late." ”

But the man did not move.

Waiting, an invigilator with an image and temperament similar to Sun Xiubin also felt that something was not quite right, and walked over quickly.

Halfway through, the hairy-haired monster suddenly raised its head sharply, stared at it and inhaled wildly.

Then, he glared and gasped.

Everyone around was taken aback.

The invigilator and the "low-profile version of Sun Xiubin" were so frightened that they stopped: "Classmate, do you need help?"

"I didn't ...... It's okay......" The hairy-haired monster gasped and shook his head.

This voice is immature and weak, but it doesn't really look like a boy's.

Li Zheng also saw it at this time, he was not even a boy in appearance, too white and delicate, with a slender face, but his eyes were very big and watery, and his eyes were full of innocence.

Not only like a girl, but also like a child......

Sure enough, it's a guy who doesn't know the height of the sky.

Shi Yang on the opposite side also looked at it for a long time, and he became shy when he looked at it.

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

At this time, "Sun Xiubin" had already walked in front of the long-haired monster and asked with concern: "Is it really okay? ”

"Ah...... It should be ......" The long-haired monster's eloquence is also okay, and he wiped his mouth hurriedly, and gradually became incoherent, "Even if it ...... You okay...... Well...... It should be......"

Li Zheng has seen a lot of this kind of shyness and transient aphasia and understands the situation very well.

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

"Ah...... Yes, I had a nightmare...... "The hairy monster hurriedly responded, glanced at Li Zheng gratefully, then grabbed the book, leaned on the table and got up and said, "I've slept for too long...... Is it time to hand in the books?"

Everyone around laughed, but there was no malice.

It's amazing that such a big person can enter the semifinals.

"Hey......", "Sun Xiubin" helplessly pointed to the cabinet in the back row of the classroom, "Put all the things that are not related to the exam there." ”

"Well, I'm sorry teacher......"

"Sun Xiubin" said solemnly: "Don't be sorry for me, it's not me who took the exam, I hope you have a correct attitude and be worthy of yourself." ”

"......" The long-haired monster turned around with a red face, just bumped into Li Zheng's smiling face, and then stuck out his tongue, laughed, and quickly slipped to the back of the classroom.

"Sun Xiubin" shook his head helplessly, then returned to the blackboard and wrote down the precautions and time arrangements for the exam on the blackboard one by one.

The hairy monster quickly came back and sat firmly, wiped his sweat for the rest of his life, and whispered to Li Zheng with his face covered: "Thank you." ”

"I can't talk about it. Li Zheng waved his hand and smiled.

Unexpectedly, this hairy monster is still quite easy to deal with.

It's just a little too casual, I haven't read through the basic textbooks, I don't have a calculator, and I doze off.

But on the other hand, if you can enter the semi-finals at will, you can be regarded as a talented person.

Li Zheng picked up the calculator and shook it: "The semi-final has a lot of calculations, so you should bring a calculator." ”

"Ah, really?"

"Well, it saves a lot of time. Li Zheng pouted at the podium, "If you're embarrassed, I'll help you raise your hand and say, there should be a few spare calculators in each examination room." ”

The hairy monster waved his hand again and again, and his face turned red again: "It's okay, it's okay...... Not ......"

"Exams are very important, what are you shy. Li Zheng leaned over and handed over his calculator, "You use mine, I'll ask for it." ”

"Don't!" the haired monster rubbed against the table in fright, "I really don't need to...... My mental arithmetic is enough. ”

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

"It's okay, I'm doing the math fast. The long-haired monster scratched his head, pushed Li Zheng's hand and said, "Thank you." ”

"Hey. Li Zheng had no choice but to shake his head and take back the calculator, "Look at your appearance, it should be a freshman in high school, right? It's okay to fail this time, learn a lesson, remember to prepare well next year." ”

The haired monster was stunned for a moment when he heard this, then he smiled and nodded stupidly: "Okay, okay, I know." ”

"Lean on ......" Li Zheng was very uncomfortable, "Can you not end up with 'la'......"

The hairy-haired monster turned his head and asked stupidly, "What's wrong?"

"Forget it...... It's good if you're happy......"

"That's it. The hairy monster laughed again.

"You're ...... enough"

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

The two hurriedly closed their voices.

Sun Xiubin then lit the blackboard and said: "Finally, I will reiterate that the exam time is from nine to twelve o'clock, with a total score of 320 points, and when the bell rings, whoever writes another word will be punished for violating the rules." ”

Everyone stared and listened, and did not dare to speak.

Everything is arranged, the bell rings, and the exam begins.

Li Zheng can be regarded as having been on the battlefield for a long time, and when he got the volume, he no longer had the surging feeling he had before.

Up and down, there is only one word -

Steady.

Don't think about grades or anything like that.

If possible, try not to think about Lin Yujing's answering situation, this is difficult, and you can only try your best.

Just like you usually do the questions, just dry them one by one like water.

Li Zheng swept towards the first question.

It is worthy of the semi-finals, and the difficulty of the first question rises.

It's said that in a station wagon, there is a small round table.

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

And now in the middle of the table, there's a cup of tea.

Q: To make the tea as large and stable as possible, how high should it be optimally loaded.

This is a very ordinary process in life, and it is probably about to be done.

But if we look at it from a physical point of view, it's a long and complex computational process.

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

Once this goal is determined.

This question has nothing to do with physics.

Moved to analytic geometry and calculus.

One more limit.

Let's connect the equations.

Remove negative solutions.

Now, is this answer just a matter of calculation?

h=mρπ²[{(1+4π5·ρr²Hm)^12}-1]

It's concise and clear, there is basically no calculation, and it's purely hot.

The second question, the villain cart.

It's just that this time it's an agricultural flatbed truck, the kind with two wheels and two rods and a big flatbed.

It's just that when you calculate it, you have to calculus or something.

There are also some simple problems of torque, rigid body mechanics, conservation of energy.

Just pay a little more attention to a bunch of 2D collision problems.

After breaking these things out.

All that's left in front of me is a math and geometry problem.

The competition is worthy of its name, and it is indeed a calculus competition for middle school students.

After Li Zheng wrote down the huge answer, he immediately looked at the side table.

The hairy monster was staring at the curly in a daze, and its eyes were cute.

Hey, you're still too young.

Let's go home and learn calculus again.
