"This ...... You've got a lot to offer. Li Zheng hurriedly put on his lab coat, put on gloves, and wiped the cleaned round-bottom flask, "Then I really did it according to my own understanding." ”

"You have to do it according to your own understanding, I don't talk the whole time, I just record. Shi Yang pulled a chair and sat down, lowered his head and flipped up his schoolbag, "The rigid routine of memory will only erase your creativity, and senior sister is such a waste." ”

What he said was actually not too much of a problem.

But Li Zheng suddenly felt a chill in front of the door.

The afterglow was swept away.

Shen Yiyun was standing at the door holding the material, his eyes wide, and he seemed to be about to become completely irritable.

"Shi ......" Li Zheng hurriedly lowered his head in fright, swallowed and spitted at the mouth, "Senior sister is only a temporary task...... Once you get into research work, you will soon be creating a ......"

"Hey, no fun, chemical inspiration doesn't just come out of nowhere. Shi Yang lowered his head and sighed, "Brother, you don't have to think too much of graduate students, just the little things they do every day in the laboratory can almost be done by practicing with an orangutan." ”

"No...... No, no...... It's different, Brother Shi ......" Li Zheng has already begun to stomp his feet.

"Hehe, maybe it's not as good as an orangutan~" Shi Yang flipped out the book and slapped the pen on the table, and raised his eyes happily, "Anyway, brother, do you think, has the senior sister ever had a boyfriend......?"

"Good afternoon, senior sister!" Li Zheng suddenly roared and saluted side-by-side.

Shi Yang was so frightened that he kicked the table and fell to the ground.

Shen Yiyun's face trembled, and he walked in without smiling: "Heh, you two are very happy." ”

"No, no, no......" Shi Yang picked up his glasses, held the platform and got up in a panic, "I, I...... I mean, the orangutan is also a higher mammal...... It is...... Orangutans aren't that different from people......"

Li Zheng said with a sneer: "Brother Shi, don't say a few words......"

"Alright, you two can do whatever you want. Shen Yiyun sat next to him with the material, "I'm just a little learned, so let's think about how to get along with orangutans." ”

Li Zheng exclaimed: "It's none of my business, don't sit with me." ”

Shi Yang's eyes widened, and they flew separately when the catastrophe came?

Li Zheng hurriedly whispered: "At least keep one alive ......"

"Makes sense...... I don't have enough emotional intelligence, and I misunderstood again. Shi Yang nodded again and again.

"Alright, I'm going to write a report. Shen Yiyun opened the materials and said, "Shi Yang, you have such a great ability, you can teach Li Zheng." ”

Li Zheng held down Shi Yang for the first time, and hurriedly said: "Senior sister, it's not like that, there is still competition between me and Shi Yang, and Shi Yang has to train and experiment by himself, so it's not convenient to teach me." ”

"That's right. Shen Yiyun looked at the collusion between the two of them, and sneered, "In this case, you do the test just now, when will you achieve 70% yield, and when will I teach you." ”

"Don't ......"

"The 80%?"

"70, just 70......" Li Zheng said busily, "I really don't have as much talent as Shi Yang, try to do it first, senior sister will take the time to take a look, and finally tutor me, okay?"

"Come on. Shen Yiyun waved his hand, "Pay attention to safety." ”

"Good. ”

Li Zheng breathed a sigh of relief.

"It's not...... Brother......" Shi Yang grabbed Li Zheng's arm and whispered, "Why did you agree? Don't you only light alcohol lamps? The first time you did such a complicated experiment, the yield was 1%, thank God." ”

"Shhhh Li Zheng said softly, "You don't understand women." ”

"Oh?"

"When a woman is angry, she must listen to it in reverse. Li Zheng nodded his head very seriously, "Think about it carefully, if I really do 70% at one time, wouldn't it be even more unnecessary for Senior Sister to exist?

"Yes...... yes......"

"So, Senior Sister, this is just a simple angry talk, and she wants me to experience the difficulty of the experiment. Li Zheng peeked at Shen Yiyun, who was seriously writing the report, and said, "As for the results of the experiment, the worse I do, the happier the senior sister will be, and the more she will come to tutor me." ”

"Awesome, brother!" Shi Yangyuan glared, "It's worthy of being a master, it's right with you!"

"Don't put on a smug look...... Li Zheng hurriedly pressed him down again, "Attention, women act according to emotions, we must not stink anymore." From now on, the more depressed we are, the better the senior sister will be in a good mood, and when I make a mess of this experiment, the senior sister will naturally smile. ”

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

"Don't deliberately, it's better to be a complete failure after some effort, very sincerely like a stupid beep. Li Zheng picked up the dropper, "Just according to what I said before, don't correct me, I'll do it according to my own understanding, the first time I did an experiment, the result will inevitably be a failure." ”

"Okay, then I'll follow what I just said, just record and don't speak, and then discuss when I'm done. Shi Yang unfolded his notebook, rolled up his sleeves and sat down.

But he watched Li Zheng anxiously study the dropper scale, and he was a little unbearable: "This...... Brother, the guiding ideology should give you some, otherwise it will be purely blind, after all, it will take three or four hours, and it is not good to waste it like this. ”

"Cheng, you say. ”

"Hmm...... Shi Yang rubbed his chin and said, "The first layer - before the experiment begins, I have figured out the principle of each step in my mind. ”

"I already figured it out when you did it. Li Zheng said, "The first step of the reaction is salicylaldehyde and malonate, which are catalyzed by piperidine to synthesize coumarin-3-carboxylate, and then add alkali to hydrolyze the ester group and lactone, and finally acidify to form a closed loop again to form lactones, which are coumarin-3-carboxylic acid." ”

"Yes, it's worthy of my brother, the theory is okay, then we'll jump directly to the second layer. Shi Yang smiled with satisfaction and said, "The second layer is to imagine the microscopic world in my mind, imagine which bond we need to tear apart in each step, which bond we need to compose, and what kind of impact each reagent will cause in this process, infer the by-products as much as possible, and after all you figure it out, fine-tune the dose and reaction environment according to your own understanding of chemistry to achieve the highest efficiency." ”

"Fuck ......" Li Zheng's eyes widened, and the student movement exploded.

While absorbing, close your eyes and wander.

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

In this world, every atom is a dot.

These dots are bound together by some kind of force called "key".

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

That's the compound.

What Li Zheng has to do is to destroy some of the "bonds" of the existing compounds, and then stick them to where he needs them.

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

It depends on other substances to do this.

The trouble is that when these substances are mixed together, they tend to cause more side reactions, break more bonds, or occupy the points that Li Zheng wants to bond.

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

How, let them crash only in the direction they want.

Come to feel it......

Combined with Shi Yang's previous piperidine overdose and ice ethanol skills, the impact of these behaviors on the chemical microscopic world is imagined......

Wonderful.

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

He suddenly opened his eyes.

And then there's the iconic glare.

[The study of history and foreign learning has reached its limit. 】

[A total of 26 student sports were obtained.] 】

[Student Movement: 4→26]

【Gain Talent - Chemical Meditation】

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

Shi Yang looked at his wonderful expression and asked in a trembling voice, "Is it so easy to understand, brother?"

"Enlightened. Li Zheng didn't have time to think about it, grabbed the dropper, nodded at Shi Yang, and said, "Thank you brother for your kindness." ”

"I'll just say a few casual words, no. ”

"As for. ”

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

By this time, he had mastered the essentials of each process of experimentation.

And I have some understanding of my own.

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

This kind of stealing is a bad feeling.

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

Li Zheng also secretly made up his mind that he must not steal teachers in the later experiments, and he must understand it himself.
