"Well... you've already provided a lot." Li Zheng hurriedly put on his lab coat, put on his gloves, and wiped the cleaned round-bottomed flask, "Then I did it according to my understanding."

"You have to do it according to your own understanding. I didn't speak during the whole process, I just recorded it." Shi Yang pulled up a chair and sat down, lowering his head and flipping through his schoolbag. "Memory of rigid routines will only kill your creativity. Senior sister is so useless. ."

There is actually nothing wrong with what he said.

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

Out of the corner of my eye.

Shen Yiyun was standing at the door holding the materials, his eyes widened, as if he was about to become completely irritable.

"Shi..." Li Zheng was so frightened that he quickly lowered his head, swallowed and said, "Senior sister only has a temporary heavy workload... Once you get involved in research work, you will soon create something..."

"Hey, no problem, chemical inspiration doesn't just come." Shi Yang lowered his head and sighed, "Brother, you don't have to think too highly of graduate students, just what they do every day in the laboratory, You can almost do it if you switch to an orangutan and practice."

"No... no no... it's different, Brother Shi..." Li Zheng had already started to stamp his feet.

"Hehe, maybe he's not as good as an orangutan~" Shi Yang took out his notebook and pen and slapped it on the table, and raised his eyes cheerfully, "By the way, brother, do you think my senior sister has ever had a boyfriend? She still... "

"Good afternoon, senior!" Li Zheng suddenly yelled, crossing his legs and saluting with attention.

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

Shen Yiyun's face trembled, and he walked in with a smile on his face: "Ha, you two are quite happy."

"No, no, no..." Shi Yang picked up his glasses and stood up in a panic while holding on to the table, "I, I... I mean, orangutans are also advanced mammals... that is... there is actually not that much difference between orangutans and humans... "

Li Zheng said with a fierce look: "Brother Shi, please say a few words..."

"Okay, you two can do whatever you want." Shen Yiyun held the materials and sat aside, "I have little talent and knowledge, so I'd better think about how to get along with orangutans."

Li Zheng was shocked and said: "This is none of my business. Don't make me sit here too."

Shi Yang's eyes widened and everyone flew away when the disaster was approaching?

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

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

"Okay, I'm going to write a report." Shen Yiyun opened the materials and said, "Shi Yang, you are so capable, you can teach Li Zheng."

Li Zheng immediately held Shi Yang down and said quickly: "Senior, that's not the case. There is still a competitive relationship between Shi Yang and I. Shi Yang has to train and test by himself anyway, so it's not convenient for him to teach me."

"That's true." Shen Yiyun looked at the two people's collusion and sneered, "Well, you do the experiment just now. When the yield is 70%, I will teach you."

"do not make……"

"The 80%?"

"70, just 70..." Li Zheng said hurriedly, "I really don't have as much talent as Shi Yang. Let's try it first. If you have nothing to do, senior sister, take the time to scan it and finally give me some guidance, okay?"

"Okay." Shen Yiyun waved his hand, "Pay attention to safety."

"good."

Li Zheng breathed a sigh of relief.

"No...brother..." Shi Yang grabbed Li Zheng's arm and whispered, "Why did you agree? Don't you only know how to light an alcohol lamp? It's the first time to do such a complicated experiment, and the yield can be 1%. Thank God."

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

"oh?"

"When a woman is angry, she must listen to her words in reverse." Li Zheng nodded his head extremely seriously, "Think about it carefully, if I really achieve 70% in one try, then wouldn't the senior sister even have no existence? Is it necessary? Is there anything else that can be given?”

"Yes...yes..."

"So, Senior, this is just an angry talk. She wants me to experience the difficulty of the experiment." Li Zheng glanced at Shen Yiyun who was seriously writing the report and said, "As for the experimental results, the worse I did, the worse the Senior The happier he will be, the more he will come to tutor me."

"Awesome, brother!" Shi Yangyuan stared, "As expected of a master, I'm the right one to follow you!"

"Don't look proud..." Li Zheng quickly pressed him down again, "Attention, women act based on their emotions. We must not be so arrogant anymore. From now on, the more depressed we are, the more senior sister will feel. Okay, when I complete this experiment to perfection, my senior sister will naturally smile."

"Okay!" 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 act very sincerely like a fool." Li Zheng then picked up the dropper, "Just follow what I said before, don't correct me, I will just follow my own rules With my understanding, the first time I conducted an experiment, the result was bound to be a complete failure.”

"Okay, then I will follow what I just said and just record without speaking. We will discuss it after I finish." Shi Yang then unfolded his notebook, rolled up his sleeves and sat down.

But when he saw Li Zheng anxiously studying the dropper scale, he couldn't bear it: "Well...brother, I'd better give you some guiding principles, otherwise it will be just a fool's errand. After all, it will take three or four hours, and it will be such a waste." It’s not good to fall off.”

"Sure, you say."

"Well..." Shi Yang rubbed his chin and said, "The first level - before starting the experiment, first clarify the principles of each step in your mind."

"I already figured it out when you were doing it," Li Zheng said, "The first step is to synthesize salicylaldehyde and malonate under the catalysis of piperidine to synthesize coumarin-3-carboxylic acid ethyl ester, and then add alkali , hydrolyze the ester group and lactone, and finally acidify to form a closed ring again to form 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 level." Shi Yang said with a satisfied smile, "For the second level, imagine the microscopic world in your mind, and imagine which key we need to tear in each step. , which bond should be formed, and what impact each reagent will have during this process. Infer the by-products as much as possible. After thinking about everything, fine-tune the dosage and reaction environment based on your own understanding of chemistry to achieve the highest efficiency. ."

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

While sucking, close your eyes and wander in a fugue.

He tried to imagine himself entering 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 "key".

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

This is the compound.

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

But, he didn't have the strength to do it with his bare hands.

It depends on other substances to complete.

The trouble is, when these substances are mixed together, they often cause more side reactions, break more bonds, or occupy the spots where Li Zheng hopes to bond.

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

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

Come and feel...

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

Wonderful.

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

He suddenly opened his eyes.

Then came the iconic glare.

[The foreign student movement in studying history has reached its limit.]

[A total of 26 student movement gains were obtained]

【Student Movement:4→26】

[Acquire Talent - Chemical Meditation]

[Chemical Meditation: You can efficiently simulate the reaction process of the chemical microscopic world in your mind, making it easier to design improved 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?"

"I understand." Li Zheng grabbed the dropper without thinking too much, nodded to Shi Yang and said, "Thank you for your kindness, brother."

"Ah? I just said a few words casually, that's not the case."

"As for."

At this point, Li Zheng embarked on his first experimental journey.

At this point, he has understood the key points of each process of the test.

And I have some understanding of my own.

Almost all of them are consistent with Shi Yang's behavior.

This feeling of stealing from others is very bad.

But what is irrefutable is that Shi Yang’s choice has reached the limit of the existing knowledge structure.
