Although Shen Yiyun said wildly that he wanted to tutor Li Zheng and Shi Yang.

But her enthusiasm didn't last long.

And soon regretted it.

From about 5:30 in the afternoon, she began to lead the two of them to explain the extremely difficult experiments at the graduate level.

The lecture lasted until 11:30, and we conducted three difficult simulation experiments.

During the whole journey, there was no need to eat or use the toilet.

This environment and work intensity are roughly equivalent to twice that of project laboratory work...

In the end, Shen Yiyun just wanted to cry.

Men are all monsters.

Sure enough, you should listen to your mother.

Why do girls want to take up chemistry?

Finally, at 11:45, under Shen Yiyun's tearful eyes, Li Zheng and Shi Yang let her go for the time being.

Then the three of us ate the fried slices and strips we brought back for lunch.

Shen Yiyun burst into tears while eating strange things she didn't want to eat.

Only then did I realize it.

Li Zheng is not as innocent as he seems.

He had already thought about this situation and packed these damn things as early as noon.

Everything, everything is included in his calculations.

Compared to these two monsters.

It’s better to be senior brother...

Those senior brothers who don’t have much hair, talk less than their hair, and are so naive that they are stupid...

It turned out to be cute.

At midnight, Li Zheng and Shi Yang finished their fried slices, but Shen Yiyun only ate half a box of La Tiaozi.

She was sad and had no appetite, so she divided the remaining notes between the two of them.

However, the two men smiled evilly at the same time and returned to the experimental table with the note.

"Hey, brother, now we have the raw materials." Shi Yang rubbed his hands and said, "The experiment we are most looking forward to can begin - first, add acidic substances to simulate gastric reactions..."

"This is naturally simple..." Li Zheng thought, "The digestibility reaction relies heavily on microorganisms, right? It requires the participation of a large number of bacteria and requires time for fermentation."

"Don't panic, biology is just a small branch of chemistry." Shi Yang raised his hand and looked around, "Considering that the raw materials here are not enough, let's give up the process and only seek the results. Let's figure out together how to use the reagents in front of us. , stretch these strips as quickly as possible until they become soft and close to tan."

"Okay, I have some inspiration..." Li Zheng just finished speaking, but then frowned and said, "But this is just an empty form and has no soul."

"Easy to handle." Shi Yang chuckled, "We can synthesize some hydrogen sulfide, indole, and skatole."

Li Zheng was surprised: "Skatole? Is there such a thing?"

"What I have studied specifically is that this is actually 3-methylindole, which can be synthesized by Fisher indole." Shi Yang raised his head and asked, "Sister, we need some aldehydes, ketones and aromatic anhydrides."

"..." Shen Yiyun had already looked at the two of them with bloodshot eyes, "Why don't you go to Prague to synthesize this kind of thing, and let foreigners take a good look at your level!"

"Isn't this appropriate... It is said that foreigners have heavier tastes than us." Shi Yang held his chin in his hands and pondered, "Is this the suspicion of trying to do what you want?"

Li Zheng hurriedly said: "No, no, Brother Shi, you are the only one worthy of being at the level of 'Ban'."

"Stop talking nonsense!" Shen Yiyun slapped the light control panel with his palm, "Turn off the lights! Go home!"

…

Even after Li Zheng and Shi Yang left the laboratory, they were still chatting wildly. Although they couldn't practice it, they were still very happy simulating the synthesis route in their minds.

In the deserted courtyard, Shen Yiyun followed the two of them miserably.

Although she was very resistant to their bad taste.

But I have to admit that their eyes were shining.

It was obviously dark night, but the whole yard seemed to be lit up.

After studying for so many years, Shen Yiyun believed that he had met all kinds of academic masters.

But like these two, this is the first time for such pure perversion.

Together, they only see chemistry itself.

The seniors in the laboratory, including myself, are all thinking about whether to stay in school or find a job, go abroad or study further, and whether to change careers to a more profitable industry.

Under the moonlight, Shen Yiyun sighed softly.

If those of us who study animals could go back to our youth, there would probably be one or two young men like Li Zheng and Shi Yang.

However, this pure time with only ideals passed faster than a shooting star.

It was gone in the blink of an eye.

Now, sister, I can only follow you from a distance, with envy, jealousy, hatred, helplessness and bitterness, longing and numbness, secretly feeling that we will eventually pass away, but once again our eternal ideal.

In the midst of their feelings, the three of them had already reached the door.

Shi Yang is still talking about "Fisher indole synthesis".

Fortunately, Li Zheng gradually got over his chemistry craze, interrupted Shi Yang at the right time, nodded to Shen Yiyun and said, "Senior, I've delayed your get off work."

"It's only a few days anyway." Shen Yiyun just raised his hand and waved, "You guys... come on, you must cherish this time."

"Definitely." Li Zheng looked around and said, "Because of this, I am going to find a fast hotel to stay."

"..." Shen Yiyun immediately panicked again, "There's no need to cherish it so much."

"I live far away, and it takes two hours to go back and forth." Li Zheng said with a wry smile, "I really can't bear to waste it. I want to do experiments, do more experiments, and make up for all the happiness that chemistry owes me."

"Have you told your family?" Shi Yang immediately took out his mobile phone and raised his eyebrows, "Isn't it a waste for one person to live in a double room?"

"You can do that too?" Li Zheng said in surprise, "That's just right. I'll pay for the room and you'll pay for the food."

"Easy to say."

Shen Yiyun looked at the heated exchange between the two and picked up his backpack strap: "Then...I'm leaving first..."

Shi Yang was really a pure person, with no brains at all, and said: "It's okay, senior, let's go together..."

Li Zheng quickly stepped on him.

Only then did Shi Yang react and lowered his head with a silly smile: "It's just... we're used to the three of us experimenting together, hehe."

Shen Yiyun just smiled.

It can be seen that this kid really didn't mean anything. The entire length of his brain circuit is on the periodic table of elements, and the rest of his IQ is also in the toilet.

"Okay, you two, come on." Shen Yiyun raised his fist and waved, "In the future, you can go higher and further than me, and you can see the true meaning of chemistry for us, the research animals."

Shi Yang scratched his head and said with a silly smile: "Don't worry, I will definitely go further than ordinary graduate students."

Damn it, this person is doing it on purpose!

Fortunately, Li Zheng was sensible and walked quickly to Shen Yiyun with a gentle smile on his face.

Shen Yiyun bit his lip and was ready.

This kid is going to say something that makes people feel numb again.

I'm afraid they'll forcefully send me back to the dormitory~~

I don’t mind~

While thinking about it, Li Zheng stared at Shen Yiyun and smiled softly: "Well, at seven o'clock tomorrow morning, Senior Sister Xinfang will open the door."

"..."

"Wait!" Shi Yang suddenly raised his hand, "It's so late, should we send the senior sister back to the dormitory, right?"

"Yes." Li Zheng finally reacted.

But Shen Yiyun had already crossed the road, shouting as if he was avoiding a nightmare: "Don't come over! I'll live in the school, you go, you go quickly!"

Shen Yiyun's three-day nightmare has officially begun.

On the other side, although the senior sister was very resistant, Li Zheng and Shi Yang still watched her enter the east gate of Jida before leaving with peace of mind.

…

That night, Li Zheng and Shi Yang each finished washing and went to bed. It was already past one o'clock.

They should have fallen asleep quickly, but the two of them were still extremely excited, tossing and turning.

What's even more frightening is that Shi Yang has good luck because he eats too much garlic.

Li Zheng regretted inviting him.

After they tossed and turned for five or six minutes, Shi Yang still couldn't hold it in any longer.
