Learning Demon Cultivation System

But her enthusiasm didn't last long.

And soon regretted it.

From around 05:30 in the afternoon, she led the two of them to practice and explain the ultra-difficult experiments at the graduate level.

Until 11:30, I did three difficult simulation experiments.

During the whole process, there is no food to eat, no toilet to go to.

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

In the end, Shen Yiyun just wanted to cry.

Men are monsters.

Sure enough, you should listen to your mother.

Why do girls touch chemistry!

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

Then the three of them ate fried slices and strips brought back at noon.

With tears in her eyes, Shen Yiyun ate the strange food that she didn't want to eat.

Only then did I realize it.

Li Zheng was not as innocent as he seemed.

He had already thought of this situation, and packed these ghost things as early as noon.

All, all are in his calculation.

Compared with these two monsters.

Still senior brother...

Those seniors who don't have much hair, talk less than hair, and are so simple and dull...

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 latiaozi.

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

However, these two people smiled evilly at the same time, and returned to the experimental table with a note in their hands.

"Hey, brother, we have the raw materials now." Shi Yang rubbed his hands together, "The experiment we are most looking forward to can begin—first, add acidic substances to simulate the stomach reaction..."

"This is naturally simple..." Li Zheng pondered, "The digestible reaction depends largely on microorganisms, right? It requires a large number of bacteria to participate, and it takes time to ferment."

"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 result. Let's conceive together how to use the reagents in front of us. , stretch these strips as quickly as possible, and become soft and close to tan."

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

"It's easy." Shi Yang chuckled, "We can synthesize some hydrogen sulfide, indole, and skatole."

Li Zheng said in surprise, "Skatole? And this thing?"

"I researched it specifically. This is actually 3-methylindole, C9H9N, 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, "You might as well go to Prague to synthesize something like this, and let foreigners take a good look at your level!"

"This is inappropriate... It is said that the taste of foreigners is heavier than ours." Shi Yang pondered, "Is this a suspicion of cheating?"

Li Zheng hurriedly said, "No, no, Brother Shi, only you are worthy of the level of 'class'."

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

……

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

In the empty courtyard, Shen Yiyun followed behind them so bitterly.

Although she is very against the bad taste of the two.

But I have to admit, their eyes shine.

Even though it was night, it seemed that the whole yard was lit up.

After studying for so many years, Shen Yiyun believed that he had seen all kinds of top students.

But like these two, it was the first time for such a pure pervert.

Together, they only have chemistry in their eyes.

And the seniors in the laboratory, including myself, are full of thoughts about whether to stay in school or find a job, whether to go abroad or to study, whether to switch to a more profitable industry.

Under the moonlight, Shen Yiyun sighed softly.

If we research animals can go back to our youth, there will probably always be one or two teenagers like Li Zheng and Shi Yang.

It's just that this period of pure time with only ideals passes faster than a meteor.

It was gone in a blink of an eye.

Now, my sister and I can only follow you far away, with envy, jealousy, helplessness and bitterness, longing and numbness, secretly feeling our eternal ideal that will eventually pass away.

Between feelings, the three of them had already walked to the gate.

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

Fortunately, Li Zheng gradually broke away from the chemistry frenzy, interrupted Shi Yang at the right time, and nodded at Shen Yiyun: "Senior sister, I have delayed your get off work."

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

"Definitely." Li Zheng looked around, "Because of this, I'm going to find an express hotel to stay."

"..." Shen Yiyun immediately panicked again, "You don't need to cherish it so much."

"My house is far away, and it takes two hours to go back and forth on the road." Li Zheng smiled wryly, "I really can't bear to waste it, I want to do experiments, do more experiments, and make up for the happiness that chemistry owes me."

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

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

"Good to say."

Shen Yiyun watched the fiery exchange between the two, and lifted his backpack: "Then... I'll go first..."

Shi Yang was also really a pure person, he said out of nowhere: "It's okay senior sister, let's go together..."

Li Zheng quickly stepped on him.

Only then did Shi Yang come to his senses, and lowered his head with a smirk: "It's just... I'm used to the three of us experimenting together, hehe."

Shen Yiyun just smiled.

It can be seen that this kid really didn't do it on purpose, the full length of the brain circuit was on the periodic table, and the rest of his IQ was also thrown into the toilet.

"Okay, you two, go for it." Shen Yiyun raised his fist and waved, "In the future, you will go higher and farther than me, and help us research animals to see the true meaning of chemistry."

Shi Yang scratched his head and said with a smirk, "Don't worry, I'm definitely going farther than ordinary graduate students."

Damn, this person did 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 will send me back to the dormitory by force~~

I don't mind~

While imagining, Li Zheng stared at Shen Yiyun, and said with a soft smile: "Then, at seven o'clock tomorrow morning, Senior Sister Hard Work will open the door."

"..."

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

"Yes." Li Zheng finally came to his senses.

Shen Yiyun had already crossed the road, and shouted as if avoiding a nightmare: "Don't come over! I live in the school, you go, you go!"

Shen Yiyun's three-day nightmare officially began.

On the other hand, although the senior sister was very resistant, Li Zheng and Shi Yang watched her enter the east gate of Ji University before leaving in peace.

……

That night, after Li Zheng and Shi Yang finished washing up and went to their respective beds, it was already past one o'clock.

They were supposed to fall asleep quickly, but the two were still extremely excited, tossing and turning.

What's even more frightening is that Shi Yang ate too much garlic and was very lucky.

Li Zheng regretted inviting him.

After five or six minutes of each other, Shi Yang couldn't hold back anymore.

Like military training or camp.

Boys share the same room, and it is impossible to fall asleep immediately after the lights are turned off.

An eternal topic will inevitably float out——

That's girls.

Shi Yang pressed his voice and asked, "Li Zheng, is that Lin Yujing pretty?"

"...Go to sleep, Brother Shi." Li Zheng reminded him kindly, "Also, don't throw up the quilt."

"Hey, breathable, breathable..." Shi Yang turned around and asked through the aisle between the beds, "Finally there is a chemistry girl, is she pretty or not?"

"...It's pretty."

"Then, is there any schoolgirl who is pretty?"

"Well... two types."

"Hurry up, tell me what type it is."

"It's... the very kind. Have you ever seen a wild cat? You want to rub it, but it runs away. When you leave, it comes back."

"Oh...it's so interesting." Shi Yang hugged the quilt and sighed, "This is a real chemistry girl...why can't I meet..."

"You think too much, she hates chemistry."

"Damn it, shut up! Don't destroy my virtual goddess." Shi Yang asked, "Let me ask you again, is Lin Yujing as good-looking as Wu Shu?"

"Brother Shi, as a chemist, you should know that the appearance of a human being is just a combination of protein and bones. There is no need to judge others by the shape of protein, right?"

"When you say that...why do I suddenly feel that everything is boring..."

"That's it, sleep."

……

In the early morning of the next day, Li Zheng regretted it even more.

As if fate collided, his and Shi Yang's convenient times were too synchronized.

Once a man grabs the toilet, no one cares about the brotherhood.

The one who goes first is refreshing, and the one who goes after is not only holding back, but also bears the remaining luck of the former.

Fortunately, Shi Yang in the laboratory knew everything.

Coupled with Shen Yiyun's guidance and the addition of student movement, Li Zheng's experimental skills can already be described as rapid progress.

As for Shi Yang, besides instructing Li Zheng, he also occupied two experimental benches. One is doing difficult experiments with Shen Yiyun, and the other is entertaining himself (80% of the time is to produce skatole), and he can ask Shen Yiyun for advice from time to time. The problem is that the improvement is not small.

Shen Yiyun was not surprised, and spent a lot of time catching up on sleep.

The day usually passes happily like this.

And at night, it must be hard.

In addition to being very "lucky", Shi Yang had to pester Li Zheng to chat with girls every night, starting from half an hour.

Li Zheng wanted to kick him into a massage parlor by the side of the road.

But think about it carefully, you can't mention this to Shi Yang.

Don't let him know that there is such a thing as a massage parlor in the world.
