Chapter 84: The Fastest Man in Shenhai (First Order, 25)

Yan Xiaoxi admitted that she did it on purpose.

Ever since someone was ambushed by other girls, this incident has been like a thorn that has been deeply stabbed into Yan Xiaoxi's heart.

The huge impact force knocked Chen Xiaoxin to the ground. Although Yan Xiaoxi didn't have much flesh, he was hit so hard that he felt very uncomfortable and almost couldn't breathe.

"Ouch."

“It feels like I was hit by a dump truck!”

Chen Xiaoxin lay on the ground, wailing, "Help! Is there anyone who can save me?"

Yan Xiaoxi blushed and quickly got up from the man. Looking at his miserable appearance, she bit her lips and said angrily, "I'll kill you, you bastard. You just want to piss me off all day long."

Chen Xiaoxin rolled his eyes and said bitterly, "If I piss you off, it's at most magical damage, but if you hit me, it's physical damage."

"roll roll roll!"

"What magic physics? Do you think we're playing an online game?" Yan Xiaoxi glared at him fiercely and said softly, "Alright, stop pretending. Hurry up and get up. The ground is quite cold."

"cut"

"Belated concern is cheaper than grass." Chen Xiaoxin curled his lips and muttered softly.

As a result,
He saw Yan Xiaoxi's hand reaching out to him, and he was so scared that he quickly stood up and took several steps back.

Yan Xiaoxi looked at him with a sneer, secretly complaining in his heart, "It's easy to control you. As long as I use my Nine Yin White Bone Claw, I'll see if you can still be arrogant."

In the following time, the two of them got along peacefully. Chen Xiaoxin played games while Yan Xiaoxi read a book beside him. Until the bell rang indicating the end of the exam, Wolong Fengchu left the library and walked into the cafeteria with the rest of the group.

"Oh my God!"

"so hard!"

One of Yan Xiaoxi's dining companions sat at the table with a sad face, saying in pain: "Why is the test paper so difficult this time!"

"Yeah yeah!"

"It's really too much. The questions are so tricky! Especially the classical Chinese. I... I can't understand it." A girl next to him said helplessly: "It's over. I'm definitely not going to make it this time. I can only score 100 points, which is an exceptional performance for me."

There was almost wailing at the dinner table, and not just at their table. Almost every table was the same. Everyone had a sad look on their faces. Of course, those poor students did not feel the difficulty of the test at all. Even the most difficult papers were the same in their eyes.

"Xiao Xi?"

"Do you have the confidence to get 140 points?" the girl asked earlier.

Yan Xiaoxi hesitated for a moment and murmured, "I don't know how many points I will lose for reading comprehension and composition, but basically there is no problem."

"Hey"

"so envious!"

The girl sighed, her brows full of admiration, and said softly: "We were all crying because of the difficulty, but you didn't feel the same at all. But then again, Xiaoxi, how much do you think Chen Xiaoxin can score this time?"

Yan Xiaoxi pursed her lips and replied calmly: "It should be higher than mine. I estimate it to be more than 145."

"To me, you two are both monsters!" The girl pouted and said helplessly, "You only took more than 30 minutes, but Chen Xiaoxin was even more outrageous. He didn't even need 30 minutes, but his score was higher than mine, who took the whole exam."

Gu Luo smiled and said softly: "The gap between people is just so big. Anyway, I have accepted it. Because I really can't compare."

finished,

Gu Luo looked at Yan Xiaoxi beside him and asked in a low voice: "Xiaoxi, in the afternoon you will have math and English. You must not make any mistakes. Suppose you are already five points behind him in Chinese, and there are five subjects left. You cannot lose points in any of them, otherwise he will widen the gap."

Yan Xiaoxi nodded, with a seemingly indifferent expression, but she was actually a little annoyed inside because at this level, every point chased was a competition between strength and luck.

After lunch,

Yan Xiaoxi and her friends returned to the classroom. The pretty girl was still studying the Riemann geometry book as before. As for Gu Luo and the others, they each took out their class notes and reviewed them nervously and seriously to prepare for the upcoming math test.

At this time,

Chen Xiaoxin and his poor academic brothers came. I don’t know what they were talking about, but the boys looked very excited.

"What are you talking about?"

Yan Xiaoxi saw him sit down and asked casually.

"Women should avoid asking about men's topics." Chen Xiaoxin answered seriously.

"."

"You love to talk but don't talk."

Yan Xiaoxi rolled her eyes and continued to read in silence.

Soon, the first exam in the afternoon came!

The invigilators were two other teachers, and they were distributing the papers at that moment.

When getting the test paper, the first thing to do is to read the questions. If you can still understand the questions in the Chinese test in the morning, then many people will collapse in the math test in the afternoon.

What the hell!

This. How difficult is this?
Those students with average grades were instantly confused, while those with good grades also frowned, feeling unprecedented pressure. As for the poor students in the last row, they still had a calm expression.

In fact, the difficulty of the test paper has nothing to do with the poor students. Luck is the most important factor affecting grades. Anyway, they just fill in ABCD randomly.
of course,

There were two king-level students, one was looking at the blue sky through the window, and the other was holding his chin with his hand, thinking about something random in his mind, and did not take the paper seriously at all.

Yan Xiaoxi came back to her senses, glanced at the questions, and couldn't help but raise her eyebrows slightly, her face full of confidence.

Full marks,

I got it!

Jingle Bell--

The exam bell rang.

Yan Xiaoxi wrote down her name, class, and school as soon as possible, and then plunged into the test questions with the best mental state.

this time
Must be faster than him!

While Yan Xiaoxi was working desperately on the questions, Chen Xiaoxin beside her was still looking up at the sky. He had no intention of doing the questions at all. The reason was very simple. Since he couldn't hand in the paper early, he might as well do the questions in the last twenty minutes before the last half hour, and then leave after finishing the questions.

Before he knew it, Chen Xiaoxin had fallen asleep while sitting there.

Chen Xiaoxin: (.-ω-)zzZ
Yan Xiaoxi was so focused that she didn't notice the situation around her at all. At this moment, she was solving the second to last question.

【f(x)=a(e^x+a)-x, find the monotonicity of f(x), and prove that when a>0, f(x)>2lna+3/2】

The question that tests the comprehensive application of derivatives is not a difficult one at all. You can find the derivative first and then conduct a classification discussion. Just pay attention to discussing the case where the derivative is always positive or always negative first during the classification discussion. As for the second question, use the monotonicity of f(x) to find the minimum value of f(x), and then prove that the minimum value is greater than 2lna+3/2.

Easy and simple!

There's only one question left.
A trace of victory flashed across Yan Xiaoxi's brows, and then she glanced at him out of the corner of her eye, but the next second, she was stunned.

null.
blank?

He. Why doesn't he write?
Yan Xiaoxi looked at a loss, but he quickly recovered. There was still a long time before the deadline to hand in the paper, even half an hour later would be enough for him.

The beautiful and smart girl pursed her lips, picked up her pen and started doing the questions on the test paper.

The last question is not very difficult. It examines the definition of parabola, the positional relationship between the straight line and the parabola, and the maximum value of the function. It’s just that the process is a little bit more, but it is still within a reasonable range.

[In the rectangular coordinate system xOy, the distance from point P to the x-axis is equal to the distance from point P to point (0, 1/2). Let the trajectory of the moving point P be W. Find the equation of W and prove that the perimeter of rectangle ABCD is greater than 3√3]

shhhhh--

【答：设P点坐标为（x，y），则由题意的：|y|=√x^2+(y-1/2)^2，整理后得到y=x^2+1/4，即W的方程为y=x^2+1/4】

Yan Xiaoxi quickly answered the questions on the test paper and finished the so-called final question in just two minutes.

twenty minutes
It should be pretty quick!
Yan Xiaoxi let out a long sigh, and her tense nerves relaxed at this moment. Then she stretched out her foot and kicked him lightly.

Chen Xiaoxin, who was wandering in the universe, was instantly pulled back to the real world. He secretly looked at Feng Chu beside him. It turned out that she had already finished. But the provocative expression on her face was quite cute.

How much time?

Oh. It took her twenty minutes.

Well, since she could finish it in twenty minutes, then as the fastest man in Shenhai, fifteen minutes should be no problem for me, right?

Chen Xiaoxin didn't know if he could finish it within fifteen minutes, but based on his past experience, it would only be faster, not slower, so he decided to give it a try and challenge his limits.

While Chen Xiaoxin was thinking, the beautiful girl next to him was getting anxious. Why didn't this stinky man respond? Hurry up and do the questions! Why are you still in a daze?
OK, OK!
You. You're not in a hurry, right?
If your time is slower than mine, I will show you how I will humiliate you!
Time passed slowly. There were less than twenty minutes left before the thirty-minute deadline to hand in the paper.

The students in the classroom all had frowns on their faces, struggling with the painful questions and unable to extricate themselves. The atmosphere in the whole classroom was filled with anxiety and boredom, but at this moment Chen Xiaoxin finally moved!
Hold the pen gently and write your name, class, and school slowly.
When my eyes moved to those questions, I couldn't help but lick my lips.

These charming little fairies
I will surrender to you now!
Start catching monsters!
The fastest man in Shenhai started, and after quickly scanning the question with his deep eyes, he got the answer instantly.
No no no
This speed is still not fast enough. If we are not careful, we will lose.

The seal is lifted!

Speed ​​up!
Chen Xiaoxin pushed the horsepower of his Kirin Arm to the maximum, overdrawing his physical strength in excitement, and his whole body turned red and hot, which was a sign that the brain's CPU was overloaded.

at the same time,

Yan Xiaoxi looked at all this and felt very disappointed.
