Learning Demon Cultivation System

"Don't act smug..." Li Zheng quickly pushed him down again, "Attention, women act according to their emotions, we must not be so arrogant. From now on, the more depressed we are, the more moody my senior will be." Well, when I make a mess of this experiment, the senior sister will naturally smile."

"Yes!" Shi Yang nodded repeatedly, "Just act like a fool, right?"

"Don't be deliberate, it's best to fail completely after a lot of hard work, and be very sincere like a fool." Li Zheng picked up the dropper, "Just follow what I said before, don't correct me, I will follow myself It is the first time I conduct an experiment, and the result is bound to be a complete failure.”

"Okay, then I will follow what I said just now. I will only record and not speak, and discuss it after I finish." Shi Yang unfolded his notebook, rolled up his sleeves and sat down.

But he watched Li Zheng eagerly studying the dropper scale, and he couldn't bear it: "This...brother, I'd better give you some guiding ideas, otherwise it will be pure nonsense. After all, it will take three or four hours at least, so it's such a waste It's not a good fall."

"Success, you say."

"Hmm..." Shi Yang rubbed his chin and said, "The first layer—before the experiment starts, the principle of each step should be cleared up in his mind."

"I figured it out when you did it." Li Zheng said, "The first step is to synthesize salicylaldehyde and malonate, catalyzed by piperidine, to synthesize ethyl coumarin-3-carboxylate, and then add alkali , hydrolyze the ester group and lactone, and finally acidify to form another ring closure to form a lactone, which is coumarin-3-carboxylic acid."

"Okay, as expected of my brother, the theory is fine, then let's jump directly to the second floor." Shi Yang said with a satisfied smile, "Second floor, imagine the microscopic world in your mind, imagine which key we need to tear apart in each step , and which bond to form, in this process, what kind of impact each reagent will have, infer the by-products as much as possible, and after all is figured out, fine-tune the dosage and reaction environment according to your own understanding of chemistry to achieve the highest efficiency .”

"Fuck..." Li Zheng stared, and the student movement exploded.

While absorbing, he closed his eyes and wandered.

He tried to imagine himself and entered the world of microscopic particles.

In this world, every atom is a point.

These points will be bound together by some kind of force called "bond".

When two or more different elements are connected together by "keys".

This is the compound.

What Li Zheng had to do was to destroy some of the "bonds" of the existing compound, and then stick it where he needed it.

It's just that he doesn't have the strength to do it with his bare hands.

To rely on other substances to complete.

The trouble is, when these substances are mixed together, it will often cause more side reactions, destroy more bonds, or occupy the points that Li Zheng wants to bond.

For this reason, Li Zheng tried his best to imagine every process and every collision between molecules.

How to make them only crash in the direction they want.

come to feel...

Combined with Shi Yang's previous piperidine overdose and ice ethanol techniques, imagine the impact of these behaviors on the chemical microcosm...

Wonderful.

Li Zheng's meditation went deeper and deeper until he penetrated the whole process.

He just opened his eyes suddenly.

Then came the iconic stare.

[Learning history and foreign student movement has reached its limit. 】

[A total of 26 students have been obtained. 】

【Student Movement: 4→26】

[Gain Talent——Chemical Meditation]

[Chemical Meditation: It can efficiently simulate the reaction process of the chemical microcosm in the mind, so that it is easier to design improved experiments and obtain more experimental inspiration. 】

Seeing his wonderful expression, Shi Yang asked tremblingly, "Is it so easy to understand, brother?"

"Understood." Li Zheng didn't have time to think, grabbed the dropper, nodded at Shi Yang, "Thank you brother for your kindness."

"Ah? I just said a few words casually, so it won't happen."

"As for."

At this point, Li Zheng started his first experimental journey.

At this time, he has mastered the main points of each process of the experiment.

And have some own understanding.

Almost all of them coincided with Shi Yang's behavior.

This feeling of stealing a teacher is very bad.

But what is irrefutable is that Shi Yang's choice is already the limit of the existing knowledge structure.

Li Zheng also secretly made up his mind that in the following experiments, he must not steal from the teacher again, and must understand it by himself.

Chapter 138 Senior Sister's Cruel Assessment

However, although Li Zheng's thinking has reached Shi Yang's level.

In practice, the movements are still stiff and messy.

Just the step of inhaling one milliliter of salicylaldehyde, he used it repeatedly for 3 minutes.

There is really no way to do this by hand.

Even if you have the idea of ​​a master chef, if you don't cook thousands of pots with your own hands, you still can't reach the level.

About this, there is nothing to say, only hands-on.

After a while, Shen Yiyun couldn't bear to see Li Zheng scratching his head at the panel of the oil bath.

She pretended to stretch, put down the materials, and strolled over to Li Zheng and Shi Yang.

"I'll just...just walk around, I won't guide you." Shen Yiyun glanced at the contents in the flask and said, "You, it's okay, but the movements are really too clumsy, and it will take a lot of time."

"Indeed." Shi Yang sighed, "But... Li Zheng is amazing. From the perspective of his technique, he is very clumsy. It must be the first time he has done it, but every step is extremely stable. In addition to hand speed and aesthetics, I also choose No problem..."

"That's right, stupid?" Shen Yiyun asked.

"That's what it means." Shi Yang nodded and said, "It's different from my style. He never takes risks, and only wants to be precise."

Shen Yiyun glanced at him and said, "Oh, you mean he has no creativity, are you looking down on people again?"

"No." Shi Yang shook his head solemnly, "This kind of precision is not conservative precision, but precise calculation precision... so stable that it doesn't make sense. Also, it's his first time doing an experiment, and he has to face his senior sister It is right to be more stable in the cruel assessment."

"Hey, is 70% cruel? You're 91%!"

"It's not the same, you let me have no theory, the first time I do it, 50% is not bad." Shi Yang stared at Li Zheng, who was gradually fascinated, "I feel that his learning direction is completely different from mine...how should I put it?" ...I'm a little flustered."

Shen Yiyun snickered and said, "Hey, is No.1 shaken?"

"Yeah." Shi Yang lowered his head slightly, looking at his trembling hands, "No...it's not panic, it's excitement...he's not a girl, how could I panic?"

"Hmph... talking about it." Shen Yiyun pouted at the big white book in front of Shi Yang, "Did you remember his mistakes and omissions in the experiment?"

"The experimental error is 0 for the time being." Shi Yang nodded, "Of course, the beauty of posture is also 0, no, -100, his movements are so stupid, I really want to beat him up."

Shen Yiyun looked at Li Zheng who was staring at the heating and reflow process like a roast duck chef on a hanging oven, and it was rare for him to agree with Shi Yang.

"I feel the same way." Shen Yiyun said with some embarrassment, "I'd better guide some movements..."

"Go away!" Shi Yang raised his hand, "This is Li Zheng's experiment."

"?! Cheng Chengcheng! I've already stepped down the steps for you." Shen Yiyun gritted his teeth, turned around and left, "Just talk, it's impossible to reach 70% in the first experiment, that's for undergraduates who graduated with excellent grades. The standard of our Ji University School of Chemistry is really easy to graduate?"

When Shi Yang heard the angry voice, he realized that he had just had a few chats with his senior sister.

He immediately became shy again.

"Okay, what Senior Sister said is right..."

"You still look down on people, you just look down on people, don't you?" Shen Yiyun returned to his seat angrily, "I wanted to think about you, success! When will the production rate be 70%, and when will you talk to me again!"

"..."

……

Before I knew it, three and a half hours had passed.

Because the whole operation was unskilled and too cumbersome, Li Zheng had already sweated profusely for two or three rounds. Fortunately, Shi Yang helped him fill the water bottle and filled two glasses of water.

At this moment, Li Zheng was a little unkempt.

But holding the watch glass and looking at the lump of white crystals on it, Li Zheng smiled energetically. It felt like he had conquered a world, and also like he had capped Lin Yujing 100 times.

"This... this is coumarin 3 carboxylic acid..." Li Zheng asked tremblingly.

"It must be. I was staring at it the whole time, and I didn't run away." Shi Yang also wiped off his sweat, and patted Li Zheng's shoulder, "It's awesome, brother, this is enough."

"It's all about stealing your skills." Li Zheng said with a smirk, "I've been thinking about it for a long time, trying to improve it, but I really can't find an entry point."

"Don't talk about improvement, you're already awesome if you can figure out my skills." The senior brother turned to look at Shen Yiyun, "Senior sister, wake up."

Shen Yiyun, who was snoring on the table, trembled instantly, stiffened his body and screamed: "No! I'm not, I'm not an orangutan, don't lock me up with the orangutan!"

"..."

"..."

This is probably a nightmare...

It seems that the senior sister's three views and self-cognition have been influenced by Shi Yang.

Shen Yiyun was stunned for a long time before realizing something was wrong, and hastily put on his glasses: "Just... just... I suddenly dreamed of "Rise of the Planet of the Apes". Movies are all movies."

After speaking, she rubbed her eyes and walked quickly.

Seeing Li Zheng's big lump made him shiver again.

"Huh???" Shen Yiyun straightened his glasses and said in surprise, "Shi Yang, did you help?"

"There really isn't one." Shi Yang took half a step back, "I guarantee it with my personality."

"No, I trust you..." Shen Yiyun quickly waved his hands, took a deep breath, put on his gloves, and put the watch on the electronic scale.

The screen displays: 2.05g.

Yield: 81%.

Shen Yiyun swallowed and spit: "Charged...is it fully dried..."

Neither of them replied, the question was so unprofessional.

"Ah...yes...then...this..." Shen Yiyun scratched his head in a mess, "Li Zheng, considering your posture, I believe it is the first time... Yield rate Here, I have nothing to say...so...you...a student like you..."

She turned her head suddenly, and looked at Li Zheng with tears in her eyes: "Must... definitely... definitely get me into the national team!"

Li Zheng was shocked.

What's wrong with you, senior?

"Prague! March tomorrow, Prague!" Shen Yiyun grabbed Li Zheng's shoulder and looked at Shi Yang at the same time, "You two perverts, go to Prague for me! Go abuse the people outside and let them see what's wrong Call it a pervert!"

"Heh." Shi Yang wiped his nose and smiled, "This is what's planned."

"Okay, hurry up." Shen Yiyun swept away his depression, scratched his head and said, "Even if we don't talk about IChO, this year's Jijing team has you... you can be called a strong pervert, I know you are very confident , but in experiments and theories, I must still be better than you, and from now on, I will seriously guide."

Li Zheng immediately began to clean the experimental equipment: "Thank you, senior."

"Really? I don't really believe it..." Shi Yang was full of doubts.

"I don't care about you." Shen Yiyun raised his hand and pulled it in front of his eyes, "You have been blocked, from now on I will treat you as if you don't exist."

Shi Yang was suddenly in a daze.

I'm just treating each other with sincerity. What's wrong with that sentence?

Why is this happening?

Also, Li Zheng is obviously not a weak baby anymore.

Senior sister, why do you become more and more pampered?

What the hell is a woman thinking? !

Chapter 139 The Most Anticipated Experiment (Single Bigger) (Revised)

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