"This...you have provided a lot." Li Zheng hurriedly put on his lab coat, put on gloves, and wiped off the cleaned round bottom flask. "Then, I really did according to my own understanding."
"I have to do it according to my own understanding. I don't speak all the way, I just record." Shi Yang pulled down in a chair and lowered her head to flip up her schoolbag. "The rigid routine of memory will only wipe out your creativity. That's why the school sister is so wasteful. ."
What he said, in fact, there is not much wrong.
But Li Zheng suddenly felt a chill in front of the door.
Yu Guang swept away.
Shen Yiyun was standing at the door holding the material, his eyes widened, and he seemed to be completely irritable.
"Historical..." Li Zheng hurriedly lowered his head, swallowed and said, "Sister Xue is only a temporary heavy task... Once it is put into research work, it will soon be created..."
"Hey, no drama, chemistry inspiration doesn't come from here." Shi Yang lowered his head and sighed, "Brother, you don't have to think of graduate students too high, just do what they do every day in their laboratory, You can almost do it if you change to an orangutan."
"No... no no... not the same, Brother Shi..." Li Zheng has already started stomping.
"Hey, maybe it's not as good as an orangutan~" Shi Yang flipped out the book and the pen on the table and raised his eyes cheerfully. "In other words, brother, do you feel that the school sister has a boyfriend? Will you like me? Type I..."
"Good afternoon, Sister Xue!" Li Zheng suddenly shouted, and paid attention.
Shi Yang was so scared that he kicked the table and fell to the ground.
Shen Yiyun shuddered, and Pei came in without a smile: "Oh, you two are very happy."
"No, no..." Shi Yang picked up his glasses and lifted the platform to panic. "I, I... I mean, orangutans are also a kind of advanced mammals...that is, orangutans are not so different from humans... "
Li Zhengao said: "Brother Shi, please say a few..."
"Okay, both of you." Shen Yiyun took the material and sat down next to him. "I'm just a little learner. I still want to think about how to get along with the orangutan."
Li Zheng shocked: "It's none of my business, don't even sit me together."
Shi Yang's eyes glared.
Li Zheng said quietly, "Keep at least one live mouth..."
"It makes sense...I have insufficient EQ and misunderstood." Shi Yang nodded again and again.
"Okay, I'm going to write a report." Shen Yiyun opened the material and said, "Shi Yang, you are so capable, you can teach Li Zheng."
Li Zheng held Shi Yang for the first time, and quickly said: "Sister Xue, it's not so counted. There is still a competitive relationship between Shi Yang and me. People have to train and experiment with Shi Yang anyway. It's not convenient for me to teach me."
"That's true." Shen Yiyun looked at the two of them sullenly and sneered. "Then, just that experiment, you first do it, when will you achieve 70% yield, and when will I teach you."
"do not make……"
"Then 80%?"
"70, just 70..." Li Zheng said busy, "I'm not as talented as Shi Yang. I'll try to do it first. I'll take a glance when I'm ok, and will you tutor me again?"
"Come on." Shen Yiyun waved his hand, "Pay attention to safety."
"it is good."
Li Zheng was relieved.
"Not...brother..." Shi Yang grabbed Li Zheng's arm and whispered, "Why did you agree? Don't you just light up the alcohol lamp? The first time you did such a complicated experiment, the yield could be 1%. Thank goodness."
"Hush." ​​Li Zheng whispered, "You don't understand women."
"Oh?"
"When a woman is angry, you must listen to the words." Li Zheng nodded his head very seriously. "Think carefully, if I really did 70% at a time, wouldn't that be a sister? Necessary? Anything else to guide?"
"Yes... yes..."
"So, Xuejie, this is just plain anger, and I want to experience the difficulty of the experiment." Li Zheng peeped at Shen Yiyun, who was seriously writing the report. "As for the experimental results, the worse I did, the more Xuejie would Happy, the more I will come to tutor me."
"Awesome brother!" Shi Yangyuan stared at his eyes. "It's a master, it's right with you!"
"Don't be complacent..." Li Zheng quickly pressed him down again, "Note that women act on emotions, we must not be stinky anymore. From now on, the more decadent we are, the more we learn about our sister's mood Okay, when I did this experiment in a mess, the school sister naturally smiled."
"Yes!" Shi Yang nodded again and again, "Just behave like a silly beep, right?"
"Don't deliberately, it's better to fail completely after a lot of effort, very sincerely like a silly beep." Li Zheng then picked up the dropper, "Just as before, don't correct me, I will follow my own Understanding, the first time I experiment, the result will inevitably fail."
"Okay, then, as I said just now, I only record and do not speak, and then finish discussing." Shi Yang then started the book and sat up with his sleeves.
But he watched Li Zheng anxiously study the scale of the dropper, and he couldn't bear it: "This...brother, let me give you some guidelines, otherwise I would just do it blindly, after all, it would take three or four hours, so wasteful It’s not so good.

"Yes, you said."
"Well..." Shi Yang said, rubbing his chin. "The first layer-before starting the experiment, first clear the principle of each step in the brain."
"I already cleared it when you made it." Li Zheng said, "The first step is the reaction of salicylaldehyde and malonate to synthesize ethyl coumarin-3-carboxylate under piperidine catalysis. , Hydrolyze the ester group and lactone, and finally acidify to form a closed ring again, forming a lactone, which is coumarin-3-carboxylic acid."
"Yes, I am worthy of my brother, the theory is OK, then we jump directly to the second layer." Shi Yang said with a smile, "The second layer, in your mind, imagine the micro world, and imagine which key we need to tear in each step. , Which bond should be formed, and in this process, what kind of effect will each reagent cause, infer the by-products as much as possible, after all figured out, fine-tune the dosage and reaction environment according to your own understanding of chemistry to achieve the highest efficiency ."
"I fuck..." Li Zheng's eyes glared and the student movement exploded.
While drawing, close your eyes and wander.
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 a force called "key".
When two or more different elements are connected by a "key".
This is the compound.
What Li Zheng has to do is to destroy certain "bonds" of the existing compounds and stick them where he needs them.
However, he does not have the power to do this freehand.
It depends on other substances to complete.
The trouble is that when these substances are mixed together, it will often cause more side reactions, break more bonds, or occupy the points that Li Zheng hopes to stick to.
To this end, Li Zheng tried his best to imagine every process in between, every collision between molecules.
How to make them only hit the direction they want.
Come to feel...
Combined with Shi Yang's previous piperidine excess and ice ethanol skills, I imagined the impact of these behaviors on the chemical microcosm...
Wonderful.
Li Zheng's meditation got deeper and deeper, until he went through the whole process.
He suddenly opened his eyes.
Then came the iconic glares.

Shi Yang looked at his wonderful expression and asked with a trembling: "Is it so easy to understand, brother?"
"Understood." Li Zheng thought less, grabbed the dropper, and nodded at Shi Yang, "Thank you Brother Daen."
"Ah? I said a few words casually, not at all."
"As for."
In this regard, Li Zheng embarked on his first experimental journey.
At this point, he was well aware of the main points of each process of experimentation.
And have some understanding.
Almost all agree with Shi Yang's behavior.
This feeling of stealing a teacher is very bad.
But it is irrefutable that Shi Yang's choice is already the limit in the existing knowledge structure.
Li Zheng also made up his mind in this regard that the following experiments can never steal the teacher any more, so he must realize it by himself.
