After the rectification was completed, the three of them sat in front of the experimental table in turn, and Shen Yiyun began to explain.

"I'll first acquiesce that you have passed the training camp and entered the provincial team. ”

"Then, your final will be held at Ludong University. ”

"The exam environment should be similar to this, an ordinary undergraduate teaching laboratory. ”

"During the experiment, there will be two invigilators who will record at any time to see if your steps are compliant. ”

Finally, according to the results of the experiment, a comprehensive score is given. ”

Shen Yiyun said, pushing a piece of paper printed with the experiment question to the two, and took out his goggles and gloves.

"You two don't have to worry, since the theory is so good, the experiment will improve quickly. ”

"The lab questions will tell you the principles and general steps, and then you will play them. ”

"The most points lost is to take it for granted, ignore some special reactions in the experiment, and add the next reagent without sufficient preparation, which will lead to errors in the reaction, and even fall short in serious cases. ”

"Because of the limited time available for the exam, if you fail devastatingly, it's all over. ”

"The rest is practice, practice makes perfect. ”

"Make all the mistakes and you'll be done. ”

"Now, I'm going to show you a simple experiment and see how it feels. ”

After Shen Yiyun finished arming, he pointed to a few bottles on the table: "Do you understand the preparation of coumarin-3-carboxylic acid?"

"Hey, hey. When Shi Yang heard this, his heart blossomed.

Start now.

It's my Shi Yang's time.

Lao Tzu has been messing around for so long, and he has never had three consecutive conversations with girls.

It's not because the girls are too superficial and don't understand chemistry, and after a little chat, they run away.

Now, here's your chance.

Ken's big sister in chemistry.

Is it you Li Zheng who can move?

Chemistry, once in the field of university.

No doubt.

Experimentation is respected.

It's time for Lao Tzu to show you hard power.

Knowledge is power.

Sister, fear the strong.

In this laboratory, I, Shi Yang, am the only king.

The more Shi Yang thought about it, the more excited he became.

But he still didn't dare to look at Shen Yiyun.

He just stared at the container and rubbed his hands, like a fat fly lying on a cake, and his mind was full of how to round this forced pretend: "This one, coumarin, isn't it last year's final question?"

"Ah, I was discovered,......" Shen Yiyun snickered, "I don't know the difficulty of this year's finals, so I have to find a question from last year, don't underestimate this experiment, it's still a bit difficult to operate, basically at the undergraduate level." ”

"Undergraduate primer, primer. Shi Yang stared at the dark brown bottle, and only raised his hand, showing a master's smile, "Put it in the national decision experiment question, it's just the primary difficulty." ”

"I'm very confident, Mr. Shi. Shen Yiyun checked the dropper and asked, "Have you done it before?"

"No, after reading this question last year, I thought it was too easy, so I didn't need to do it. Shi Yang pursed his lips and waved his hand shyly.

How's that, big sister?

How's it going to be under this forced pretend?

saw Shen Yiyun's hand shake, and the dropper almost fell.

"Oops, I almost got a point. Shi Yang was very clever, and immediately raised his eyebrows and smiled, "Damaged equipment, three points a piece, you don't have a full score." ”

Shen Yiyun's teeth tensed.

Even though she's notoriously good-natured, she hates this guy a little.

Shi Yang won the awe of his chemistry sister, but he became more and more majestic: "Speaking of experiments, ICHO is indeed a little bit difficult, but this national final question, as long as the experimental equipment is not faulty, I can basically get a full score." ”

Shen Yiyun pouted.

Hold your chest and be unhappy.

Didn't I come to tutor you?

You're so strong, why are you here?

Li Zheng is no better than Shi Yang, and he knows how to read words and feelings.

Seeing that Teacher Shen was unhappy, he hurriedly persuaded: "Brother Shi, we are here to study, watch it first, and then talk after reading it, don't interfere with Senior Sister." ”

Shen Yiyun is more comfortable at this time, but fortunately, this younger brother is sensible.

But seeing Shi Yang raising his eyebrows and smiling again, with the big face and crescent moon eye shape, when he smiled, there was a little obscenity in his demonic nature: "Oh, such a simple experiment, do you still need someone to counsel, let's have a difficult one, right?"

Shen Yiyun gritted his teeth again.

You haven't won the country yet.

You're starting to look down on me?

"Then, let's do it......" Shen Yiyun held back his anger and took off his goggles and gloves, "Classmate Shi Yang, you can show us this." ”

"This ......" Shi Yang was a little embarrassed, frowned, "It's too simple, I don't see the level......"

Shen Yiyun looked at him like this, and pinched the table with anger: "I...... I...... I didn't think it was easy. ”

"Really?" Seeing this, Shi Yang immediately took over the gloves and goggles, "Then I'll let you see it?"

In fact, he still has half a sentence "That's it?"

I just suffocated it.

Although he really wanted to show the charm of a strong chemical man, he could also feel that it was not good to step on people like this.

In the strange atmosphere, Shi Yang finished arming and came to the front of the stage.

Once he started the experiment, the flesh on his face rippled excitedly: "Look, I lose if I deduct half a point." ”

"Please. Shen Yiyun stood opposite and glared.

If you don't believe me, I'll detain you.

Li Zheng saw that he couldn't persuade him, so he had no choice but to come to Shen Yiyun's side and say in a very low voice.

"Senior sister, my brother, is not very good at talking, I believe he is not intentionally offended, but as soon as he enters the experimental environment, he will not be able to control himself and behave a little exaggerated. ”

"It's okay, it's okay. Shen Yiyun raised his arm and breathed a sigh of relief.

At this time, he glanced at Li Zheng again, and the more he looked at it, the more pleasing it became.

It's also a junior.,Although this one doesn't seem to be good at studying.,But it's very well-behaved.。

She asked kindly, "I'm too lazy to take care of him, how is your experimental basis?"

"I have no foundation, I just know that the alcohol extinguishing lamp can't be blown and must be covered. Li Zheng nodded ashamedly, "Although it is the second in theory, I also feel that I may not be able to enter the provincial team, and it all depends on the guidance of my senior sister." ”

"Ji Jing was second in the preliminary round, and he is already much better than me. Shen Yiyun waved his fist and encouraged, "Come on, fight for escort." ”

Li Zheng humbly excused himself as before: "Eh, I don't dare to think too far, it's true to work hard to enter the provincial team." ”

"Relax, I'll tutor you for three days, and the training camp will be enough. ”

"Three...... Three days?" Li Zheng was overjoyed, but he exerted his emotional intelligence and excused himself, "Is it too much to delay my senior sister's studies?"

Shen Yiyun blinked his eyes a few times, and then said with a wicked smile: "Don't worry, teaching you, it's better than working overtime in the laboratory~ I don't lose either~ I am also a teaching assistant in the back training camp and the Golden Autumn Camp~ I can fish for a long time~"

Li Zheng inquired: "Speaking of overtime in the laboratory, it must be very tiring, right?"

"Oops, oops...... It was busy until more than ten o'clock every night...... This professor still thinks we get off work early, I'll tell you a real joke......" Shen Yiyun's eyebrows fluttered and he said, "Because our mentor is too ruthless, there is a senior brother who can't stand it, and wrote a report letter to the dean, saying that he oppressed us and had to experiment until late at night every day, and then the dean found out, so he was very angry and called our mentor, probably saying this——"

Shen Yiyun pretended to be the dean's respectful appearance, and reprimanded him in a respectful manner: "Oh, what's the matter, Lao Yang, how can you call the students like this, you must let them go home early, before 11 o'clock!"

Immediately after, she took another step forward and imitated the teacher's submissive appearance: "No, dean...... I let them go back at 10 o'clock. ”

Shen Yiyun finished speaking, and looked at Li Zheng expectantly.
