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.

It's like military training or some kind of camp.

When boys sleep together, it is impossible to fall asleep immediately after turning off the lights.

An eternal topic will inevitably come up——

That's girls.

Shi Yang lowered his voice and asked, "Li Zheng, is that Lin Yujing beautiful?"

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

"Hey, breathable, breathable..." Shi Yang turned around and asked across the aisle between the beds, "Finally, there is a chemistry girl, is she pretty?"

"...It's pretty."

"Then, are any of the seniors pretty?"

"Well...two types."

"Quick, quick, tell me what type it is."

"It's just... the kind that's worth a lot. Have you ever seen a wild cat? You want to go up and rub it, but it runs away. When you leave, it comes back."

"Oh... this is so interesting." Shi Yang sighed while hugging the quilt, "This is a real chemistry girl... Why can't I meet..."

"You're overthinking it. She hates chemistry."

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

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

"If you put it this way...the chemical composition of the human face seems to be similar to that of feces."

"Sleep...sleep...please."

…

The next morning, Li Zheng regretted it even more.

As if their fates were in conflict, his and Shi Yang's convenient times were too synchronized.

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

The first one is refreshing, the second one is not only suffocating, but also has to deal with the lingering smell.

Fortunately, Shi Yang in the laboratory knew everything.

Coupled with Shen Yiyun's guidance and the bonus of academic performance, Li Zheng's experimental skills can be described as rapid progress.

As for Shi Yang, in addition to guiding Li Zheng, he also occupied two experimental benches. One followed Shen Yiyun to do difficult experiments, and the other entertained himself (80% of the time was used to produce skatole). From time to time, he could also ask Shen Yiyun for help. Yiyun asked some questions and also improved a lot.

No surprise to Shen Yiyun, he spent a lot of time catching up on sleep.

The day usually passes happily like this.

But at night, it must be very difficult.

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

Li Zheng even wanted to kick him into a massage parlor on the roadside.

But if you 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.

On Thursday night, the three-day experimental assault finally came to an end.

Shen Yiyun has been transformed into a human being and is about to witness the four o'clock sun in Jijing.

But she finally treated Li Zheng and Shi Yang to a hot pot buffet.

After all, I haven't eaten much seriously these days.

Li Zheng usually eats clear soup and little water at home. He has become accustomed to a light diet, so he is doing fine these days.

But Shi Yang was really choked up, and he kept eating from the beginning to the end of the buffet. He ate for two hours, which was roughly equivalent to two or three times the amount of Li Zheng and Shen Yiyun combined.

When we finally parted...

In fact, no one feels any difference at all.

Because there will be a training camp on Saturday, we will meet again. Not only Li Zheng and Shi Yang, but Shen Yiyun is also one of the instructors of the training team.

Even so, Li Zheng and Shi Yang still made a vow to each other——

You must successfully synthesize enough skatole in the National Finals Winter Camp.

…

Li Zheng returned home after three days and finally had a solid sleep without girls talking about him or "luck".

In the dream, he prayed that he must not be in the same room with Shi Yang during the training camp.

The next morning, Li Zheng didn't wake up until after nine o'clock. There was no teacher to care about him at that time, so he simply took another day off and studied at home.

After the rectification is completed, routine acceptance will be carried out.

It must be said that the experiment opened a new door to learning chemistry.

After three days of intense baptism, the chemistry score has reached an outrageous level of 286.

What's even more pleasant is that since the experiment can only be done at a normal speed, more than two hundred hours of vitality have been saved in the past few days.

With the remaining warmth of the experimental breakthrough.

It's time to kill the Tongguo Jue textbook.

With the talent bonus of [Chemical Meditation] and [Chemical Frenzy], facing "Analytical Chemistry", "The Art of Writing Organic Reaction Mechanisms", "anic", "Organic Synthesis - Cut-off Method", these involve complex experiments , some difficult books.

Li Zheng just hopes... that he can finish eating it slowly and enjoy the difficulty more.

It's a pity that God did not fulfill people's wishes.

He ate them all in two hours.

In the remaining time, I can only simulate a few sets of previous years' national final exam questions at a normal speed.

That night, Li Zheng went to bed very early. After all, the provincial team training would begin the next day, and spirit was very important.

What is different from the past is that this training camp is held simultaneously with the Golden Autumn Camp, and the location is still Ji Dahuayuan.

If you sign up for the Golden Autumn Camp, your training performance will be equivalent to the Golden Autumn Camp inspection.

In other words, the top performers in the training camp will not only be included in the provincial team roster, but will also have a high chance of signing with Jida in advance.

Under this opportunity, classmates and teachers from all walks of life also sent blessings in advance.

[Tang Zhifei: Go to bed early, work hard, and perform well, you didn’t bring out Ji University students just because I became the class teacher for the first time!]

[Li Zheng: Drink more hot water and wash your feet frequently.]

[Tang Zhifei: Your wings are strong, right? Now you dare to talk and laugh with the principal, right? 】

…

[Yu Hong: Li Zheng, I originally did not advocate putting pressure on you, but the principal has always put pressure on me. As the only child in Yinghu Lake, I wish you do what you say and achieve immediate success. 】

[Yu Hong: By the way, the top person in charge of the training is Mr. Zhou Yi, the deputy dean of Jida Chemical Institute. He is the best teacher in the country. When doing his questions, pay special attention to organic ring-forming reactions. 】

[Li Zheng: Okay, thank you, Teacher Yu. In addition, I have some invoices here.]

[Yu Hong: It’s getting late, have a good rest.]

…

[Zhang Xiaoke: Master... when you were away, the class seemed to have no soul, and I was so bored...]

[Li Zheng: You wish you could relax a little, right? 】

[Zhang Xiaoke: No, I want to study and feel that I can go to a better school. 】

[Li Zheng: Then wait a moment, I will send you a few sets of exercises. 】

[Zhang Xiaoke: Okay, I’ll give it to you after I finish it on Monday.]

[Li Zheng: I am not used to your performance...]

[Zhang Xiaoke: Are you afraid of being overtaken? 】

[Li Zheng: You are overthinking, there are at least 50 **huas between us. 】

…

[**Hua: Well, everyone is encouraging you, let me say something disappointing.]

[**Hua: There is heaven outside the world, there are people outside the world, and blows are inevitable. Adjust your mentality as soon as possible. Don’t be heavy for too long. It is too difficult to let go. Just keep a normal mind. 】

[Li Zheng: Thank you for your concern, I am very happy. By the way, how is Lin Yujing these days? 】

[**Hua:...Why do you have to ask me?]

[Li Zheng: I can trust it. 】

[**Hua:...Well, she also took a leave of absence and seems to be studying college physics at home.]

[Li Zheng: Very good, then I’ll let her go for another month. 】

…

[Xu Mengxi: I originally wanted to cheer in person, but you’re not here, so—come on>_

[Li Zheng: Thank you, Teacher Mengxi, I like chemistry more and more. 】

[Xu Mengxi: Ha! Isn’t it fun to think about the reaction process? 】

[Li Zheng: Yes, especially if it’s organic, don’t be too excited when forming rings. 】

[Xu Mengxi: Ah...ah, right...right, right...]

[Li Zheng: For example, 3-methylindole is very troublesome to synthesize. Do you know phenylhydrazine? 】

[Xu Mengxi: Oh... don’t disturb your sleep, come on>_

…

In addition, Qiao Bixia, Liu Xin, Qiao Sheng, and Hu Chunmei also wished success.

Of course, the real excitement was the learning sharing group established by Li Zheng when he promoted teaching materials.

Now, there are nearly 200 alumni here, and even the junior high school is involved.

I don’t know who changed the group name to [Muzheng Base Area].

Everyone’s group business cards have also become magical.

[I am completely stunned: Li Shen will go to the provincial team tomorrow, if you have anything to say, please tell me as soon as possible! 】

Li Zheng stared, wasn't this husky portrait Zhang Xiaoke?

There were responses below.

【Li Shen is awesome!】

[I will buy 20 more textbooks after entering the national finals!]

[Li Shen hasn’t posted a question for several days, I feel bad.]

【Hey, you are addicted to chemistry and ignore us.】

Li Zheng's hands started to itch now.

[Li Zheng: This is the first time I see this kind of request. I will satisfy you.]

[Li Zheng: "Complete Solutions to Middle School Textbooks" (29 volumes), "All-purpose Book for College Entrance Examination Review Handouts", "5.3 Question Master", "College Entrance Examination Help for Mathematics, Physics and Chemistry Students" Set "1000 Essential Question Types for College Entrance Examination Physics"...]

[I was wrong Li Shen... I never dare to do it again...]

[I was completely stunned: Master, if you have the ability to carry a national fund... If you come back to the top ten in the country, I will buy everything mentioned above!]

[Fuck, fuck, fuck... you are indeed a little kid and a great grandma...]

【Can't afford to offend, can't afford to offend...】

[Li Zheng: I didn’t have such a high goal originally, but for you, I am willing to fight for it. 】

[I was completely stunned: Is this... top... top five okay? 】

[Li Zheng: You should save money first. If you get all the above, you might be able to buy a car. 】

【I am completely stunned: Let’s discuss it again (;′??Д??`)】

At the same time, the Dragon Balls are also eager to try.

However, the discussion there was more utilitarian. It was mainly about guessing how many signing quotas there would be for this training camp. The group leader Ou Xingzhuo was using his experience in previous years to show off. Shi Yang said in the middle that he had a stomachache and stopped talking.

Below.

Li Zheng put down his cell phone and started tossing around.

It lasted until about ten o'clock and still didn't fall asleep.

My heart is not at peace...

He was obviously not nervous at all, which was strange.

When he was tossing and turning, he would always pick up his phone and take a look to see if there were any missed blessings.

During this period, Wangcai kept jumping on the bed and walking around, probably because he was itchy from not being rubbed for several days.

Li Zheng just fell into the cycle of turning over → going to the toilet → petting the cat.

Until 11 o'clock, he was still in a daze holding Wangcai.

Thumb thump thump~

The cell phone rang suddenly.

Li Zheng instantly threw Wangcai five meters away and grabbed his cell phone.

【Lin Yujing:~】

Li Zheng raised the corner of his mouth.

Then it took three minutes and forty seconds to reply.

【Li Zheng: You woke me up.】

[Li Zheng: Are you bothering me so late, do you want to prevent me from entering the provincial team? 】

【Lin Yujing:~】

[Li Zheng: I know that you took a few days off to study physics at home. 】

[Lin Yujing: (fierce)]

[Lin Yujing: I heard that there is a chance to sign a contract with the Institute of Chemical Technology.]

[Li Zheng: Yes.]

【Lin Yujing:~】

[Li Zheng: What, are you jealous? If you want to come, just say it, it might be too late now. 】

[Lin Yujing: Hate chemistry (covering face and crying)]

[Lin Yujing: If you could sign, would you sign? 】

[Li Zheng: Well, Jida is indeed a good school, and chemistry is also a top subject. 】

[Lin Yujing: To sign, or not to sign? (fierce)]

[Li Zheng: Why, do you care about this matter? 】

[Lin Yujing: (whistle)]

【Lin Yujing, let me ask.】

[Li Zheng: Let’s talk about it then. I’m going to sleep, so don’t disturb me. 】

[Lin Yujing: Don’t you like chemistry? 】

[Li Zheng: Suddenly I like it. 】

[Lin Yujing: Stupid pig’s hooves! Slag, scum, scum! 】

[Lin Yujing: I wish you zero points in the experiment! 】

【Lin Yujing: Sleep!】

After a confrontation with Lin Yujing, Li Zheng put down his phone and finally felt comfortable and began to feel sleepy.

Should I remove the Jingda or Jinghua?

Should I go to the School of Physics or the School of Chemistry?
Chapter completed!
