After finishing the arrangement, the three of them sat down in front of the experimental table one by one, and Shen Yiyun began to explain.

"I'll give you the tacit approval that you passed the training camp and entered the provincial team."

"Then, your finals 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 taking notes at any time to see if your steps are in compliance."

"Finally, a comprehensive score will be given based on the experimental results."

As Shen Yiyun spoke, he pushed a piece of paper with experimental questions on it to the two of them, while he took out his goggles and gloves.

"You two don't have to worry. Since the theory is so good, the experiments will improve very quickly."

"For the experimental questions, I will tell you the principles and general steps, and then it's up to you to perform."

"The most points lost is taking it for granted, ignoring some special reactions in the experiment, and adding the next step of reagents without sufficient preparation, resulting in reaction errors, and in serious cases, even failure."

"Because the exam time is limited, if you suffer a devastating failure midway, it will be all over."

"The rest is just practice, practice makes perfect."

"Make all the mistakes again and you will know how to do it."

"Now, I will show you a simple experiment first, and you can see how it feels."

After Shen Yiyun finished arming himself, he pointed to several bottles on the table: "Do you know anything about the preparation of coumarin-3-carboxylic acid?"

"Hehe." Shi Yang felt happy when he heard this.

Start now.

It's my time to be Shi Yang.

I've been around for so long, but I've never spoken to a girl for more than three consecutive sentences.

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

Now, the opportunity has come.

The chemistry big sister of the second grader.

Is it you, Li Zheng, who can seduce you?

Chemistry, once it enters the university field.

no doubt.

Experimentation is respected.

It's time for me to show you my hard power.

knowledge is power.

Girls, 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 together, like a fat fly lying on a cake. His mind was full of how to make this look smooth: "This, this, coumarin, wasn't last year's final question?"

"Ah, it 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 is still a bit difficult to operate. Basically Undergraduate level.”

"Basic entry level, entry level." Shi Yang stared at the dark brown bottle, raised his hand, and showed a master's smile, "If you put it in the national final test questions, it would be at the entry level level."

"You are very confident, Mr. Shi." Shen Yiyun checked the dropper and asked, "Have you done this 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 hands shyly.

How about it, big sister?

How are you doing with this fake show?

However, Shen Yiyun's hand shook and the dropper almost fell.

"Oops, you almost got a point deduction." Shi Yang was very clever and immediately raised his eyebrows and said with a smile, "Damage equipment, three points for each item, and you lose the full points."

Shen Yiyun's teeth tightened.

Even though she is famous for her good temper, she still kind of hates this guy.

In order to win the awe of the big sister of chemistry, Shi Yang became more and more impressive: "Speaking of experiments, Icho is indeed a little difficult, but as for this national final test, as long as the experimental equipment does not malfunction, I can basically get full marks. of."

Shen Yiyun pouted.

Cross your chest, unhappy.

Am I not here to tutor you?

You are so strong, what are you doing here?

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

Seeing that Teacher Shen was unhappy, he quickly advised: "Brother Shi, we are here to study. Let's read it first and then talk after we finish it. Don't disturb the senior sister."

Shen Yiyun felt more comfortable now. Fortunately, this younger brother was sensible.

But Shi Yang raised his eyebrows and smiled again. Matching his big face and crescent-moon eyes, when he smiled, his devilish nature actually gave birth to a little bit of vulgarity: "Oh, do you still need help from others for such a simple experiment? Let's do a difficult one? "

Shen Yiyun gritted his teeth again.

You haven't gotten the first grade in the national level yet.

Are you starting to look down on me?

"Then, let's do this..." Shen Yiyun held back his anger and took off his goggles and gloves, "Classmate Shi Yang, come and demonstrate it for us."

"This..." Shi Yang was a little embarrassed and frowned, "It's too simple, it doesn't show his level..."

Shen Yiyun looked at him like this and was so angry that he picked up the table surface: "I...I...I don't think it's very simple."

"Really?" Seeing this, Shi Yang immediately took over the gloves and goggles, "Then let me show you what it is?"

In fact, he still had half a sentence: "This is Ji Dayan Er?"

I just had to hold it back.

Although he wanted to show off his charm as a strong chemist, he also felt that it was not good to step on others like this.

In the weird atmosphere, Shi Yang was armed and came to the stage.

Once he started doing the experiment, the flesh on his face rippled with excitement: "Look, I will lose half a point."

"Please." Shen Yiyun stood on the opposite side and glared at him.

If you don't believe it, I'll kill you.

Seeing that he could no longer persuade him, Li Zheng had no choice but to move closer to Shen Yiyun and said in a low voice.

"Senior sister, this brother of mine is not very good at talking. I believe he didn't mean to offend, but once he entered the experimental environment, he couldn't control himself and acted a little exaggerated."

"It's okay, it's okay." Shen Yiyun raised his arms and took a deep breath.

At this time, I glanced at Li Zheng again, and the more I looked at him, the more pleasing I was.

They are also junior students. Although this one doesn't seem to be good at studying, he is very well-behaved.

She then asked in a friendly manner: "I'm too lazy to take care of him. How is your experimental foundation?"

"I have no foundation at all. I only know that I can't blow out the alcohol lamp, but I have to cover it." Li Zheng nodded shamefully, "Although I am second in theory, I still feel that I may not be able to join the provincial team. I completely rely on my senior sister's guidance."

"Jijing was second in the preliminary round and is already much better than me." Shen Yiyun waved his fist and encouraged, "Come on, try to get a walk-off."

Li Zheng declined as humbly as ever: "Hey, I don't dare to think too far yet. It's true that I will work hard to get into the provincial team."

"Relax, I will teach you well for three days, the training will be enough."

"Three...three days?" Li Zheng was overjoyed, but he used his emotional intelligence to decline and said, "Would it delay senior sister's studies too much?"

Shen Yiyun blinked a few times quickly, and then said with a bad smile: "Don't worry, teaching you, it's easier than working overtime in the laboratory~ I won't lose either~ I will also be a teaching assistant in the later training camp and Golden Autumn Camp~ I can fish for a long time. ~”

Li Zheng inquired: "Speaking of working overtime in the laboratory, you must be very tired, right?"

"Oh my god... I'm busy until after ten o'clock every night... This professor still thinks that we get off work early, let me tell you a real story..." Shen Yiyun beamed and started talking, "Because Our tutor was so cruel that one senior brother couldn't stand it anymore and wrote a letter of complaint to the dean, saying that he was exploiting us and had to experiment until late at night every day. When the dean found out, he became very angry and called our tutor. , that’s probably what he said——”

Shen Yiyun pretended to be a respected dean and scolded him in a dignified manner: "Oh my god, what's going on? How can you boss the students around like this, Lao Yang? They must be sent home early, before 11 o'clock!"

Immediately afterwards, she took another step and imitated her tutor's submissive manner: "No, Dean... I will let them go back at 10 o'clock."
