In the chemistry teaching and research room, Li Zheng, Lin Yuejing, and Xu Mengxi, who were originally masculine and energetic, came to kill the subject with thunder.

But just hit the first question, it seems to be stuck in a gossip array-

[One, according to the conditions, write the chemical reaction equation]

[1-1: Industrially, using ammonium bicarbonate and magnesia (Mg2B2O4(OH)2) to prepare boric acid in an aqueous solution]

Li Zheng: What the **** is this? My chemistry is really 150+?

Xu Mengxi: Don't panic...don't panic...analyze carefully...step by step...don't panic...no...no wow!

Lin Yujing: Well...>.<.

However, this is only the first sub-topic of the first one.

The simplest and simplest question.

Correct, only 2 points.

Li Zheng now knows why Sun Leyang said that he can get 10 points is the big brother.

Despite the horror, Li Zheng still did not drive 56 times faster.

This time, he just wanted to know his true level.

Go home again.

...

Three people work hard to solve the problem, and the concept of time is completely gone.

Until the preparation bell rings.

Li Zheng looked up in horror.

What a joke?

Only did 1/4.

But listening to Yu Hong said: "Mr. Sun has gone to class, I have greeted Mr. Tang, you continue to do, the exam time is three hours, don't worry."

Li Zheng was relieved and glanced down at the two people next to him.

Xu Mengxi's answering progress is almost the same as his own.

Lin Yuejing lay on his side on the table and turned the second interview paper weakly.

Li Zheng stared.

what's the situation?

Already started to answer the second one, more than half of the progress?

Did you even steal university chemistry?

Too **** cunning.

Li Zheng did not have much time to think about it, and returned to the noodles again.

[In the metal ion M3+ solution, add acid HmX, control the conditions, you can get different precipitation. pH<1, precipitation A(M2Xn·yH2O, y<10)......】

Damn you.

What is this saying...

No matter, do it hard.

...

Unconsciously, all three were turned into problem machines.

The bell rang again and again, but they turned a deaf ear.

Finally, Yu Hong clapped his hands: "Okay, Teacher Sun has been waiting for a long time, three and a half hours."

Boom.

Lin Yujing photographed the pen and died at the table with one hand, scratching his head with both hands, shaking and shaking, and there was an unprecedented painful moan: "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh'p More more than 30% of the shots had been slammed, and the hands shook their heads, shook and shook, and there was an unprecedented painful groan: "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!!!! "

Beside, Xu Mengxi's hand fell softly and the pen fell to the ground.

Staring at the white wall, his eyes were empty and he collapsed.

It seems to have gone through a lame life.

Li Zheng's brain was already chaotic. After throwing away the pen, he leaned blankly on the back of the chair and gasped.

It's as if the bomb ripper had just cut the red thread.

The rest of the life.

At the same time, Li Zheng's mouth twitched endlessly, and I don't know when, he had meditated on the meditation curse that would only start when he learned to crack: "Nan Wu, drink Luo Ling, Duo Luo Ye Ye... Nan No, Ah yeah... Emperor Poluqi... Shuobo Luoye..."

no doubt.

All three of them collapsed.

Do the question, do it broken.

Yu Hong also saw this for the first time and was amazed.

"Hey." Sun Leyang smiled steadily. "It's the same for the first time. Hey."

At the urging of Yu Hong, Lin Yuejing and Xu Mengxi helped each other to the toilet.

Li Zheng was even softer even with the crutches.

When urinating, the abduction had not stabilized and fell to the ground.

Boom!

Li Zheng smashed the lower wall hard.

Is this the realm of genius...

Too... so **** difficult...

It's harder than elementary school to go to the Olympics.

That Olympiad can still get at least two or thirty.

This one, I really don’t even have confidence in 10 points...

What else challenges me... Masters learn...

It's all perverted! That pile of games is all perverted!

With such a painful mood, Li Zheng almost nurtured the urinal.

After finishing things, he found that Lin Yuejing and Xu Mengxi were leaning by the window of the corridor, shaking.

"Hmm..." Lin Yuejing trembled tremblingly and took out a piece of mint candy, tearing the packaging several times, but couldn't tear it apart, throwing it to the ground with anger, holding his head mad.

Xu Mengxi stared out of the window without saying a word.

Li Zheng leaned over and made a difficult leaning over to pick up the sugar, then tore the wrapping paper firmly, and handed the white candy to Lin Yuejing: "Give it."

Lin Yujing froze for a moment, but after a bit of entanglement, he still reached for his hand.

I saw that Li Zheng suddenly retracted it, frowning and said, "I don't seem to... wash my hands... forget it, eat it yourself."

He threw it into his mouth.

"?!"

Lin Yuejing wanted to scratch people.

"Don't be so stingy." Li Zheng raised his hand. "I've given you so many medicines. You're still breathing after eating your candy."

"Ha!" Lin Yuejing couldn't hold it anymore, and he scratched Li Zheng's arm when he went up.

"You're really scratching..." Li Zheng suffered from pain and quickly turned back two steps.

Although, when I first went to the toilet, there was a lot of negative energy.

But he has gone out all the time.

"If it doesn't work, I will get zero points." He said frankly to the two, "but I will still participate, and I will participate in self-study."

Lin Yuejing flinched into the corner, closing his eyes and covering his ears, refusing to hear everything related to the competition.

Xu Mengxi strongly supported the window and turned to Li Zheng: "You can, after all, there is still one year left."

"No, I only participated in this year." Li Zheng tried his best to make his tone show modesty, "I have checked the time, and I will participate in the physics math competition next year."

"Well 5555..." Lin Yuejing kicked his leg hard in fright, and he was all trembling. Looking at Li Zheng was like watching a devil.

"You're really...strong enough..." Xu Mengxi shook his head and sighed at the window. "I won't do it...this is my chance. I guess, the standard for the second province is about 40 points... ...It's unlikely..."

If it is usual, Li Zheng must be encouraged.

But now it is different.

Even if he is passionate about abuse, he also realizes what is real terror.

This is not so simple as despair, but kills all your passion for a subject.

"Well, don't do it if you can't." Li Zheng stepped forward and comforted, "Full-hearted college entrance examination, enter 985."

"Let you say good things..." Xu Mengxi turned to Lin Yuejing, "quietly what you did... probably how many points..."

Lin Yuejing closed his eyes and shook his head >.<, refusing to remember.

The three of them let the wind blow for a long time before finally relaxing and snuggling back to the chemistry teaching and research department.

Pushing the door open, Sun Leyang and Yu Hong were sitting silently without saying a word.

Why, even they can't hold the paper?

When the three of them approached, Sun Leyang shivered and stood staring at Lin Yuejing.

"Lin Yuejing, you are already the second province."

"???

Sun Leyang picked up the test paper excitedly: "52 points! Do you know how much to save the first line? 55, 3 points to save one! Still no training, you, you are going to enter the national team."
