"It's really not false." Wu Shu's face was full of solemnity, "The experiment is going to be a waste of time."

"Make it up together, make it up together."

"Okay, then I'll share the information with you as well." Wu Shu stuck to Li Zheng's ear again, and whispered in a serious manner, "For Zhou Yi's camp, ring formation is very important, and more rings can get high scores. "

"This...doesn't seem like a secret." Li Zheng couldn't help but said, "Your information is too sparkling."

"Oh! Isn't the word Mars not Mars?"

"Forget it." Li Zheng waved his hand, "The gods are all floating clouds."

"You...you won..." Wu Shu trembled all over, closed his eyes and said in a trembling voice, "Old Gen... can't beat you."

Li Zheng snorted and said, "Chengrang, I also used the prehistoric power in my body."

"It's enough for you, please spare me! Hahaha..." Wu Shu laughed wildly while crossing his arms and begging for mercy, "I can't stand this..."

Chapter 143

"Oh?" Li Zheng immediately became excited when he saw her wanting to refuse and welcome, "Don't be obsessed with brother, brother is just a legend~"

"Oh, it's so embarrassing." Wu Shu finally couldn't help it anymore, bent over and hugged his belly and laughed wildly, "Stop, stop quickly hahaha."

How is it possible, like just learning how to scratch an itch, how can it be stopped.

"That's amazing, my brother." Li Zheng rubbed his hands together.

"Haha, you are enough."

"What brother eats is not noodles, but loneliness."

"Okay, please, I'm going to die haha!"

Li Zheng had a great time playing the old meme, but he didn't know...

More than 40 men with crew-cut glasses who came to gather had already been staring at him with bloodshot eyes.

The only girl in the whole camp, the official physics queen recognized by all the top students...

Why, did you make it like this?

The queen is dead!

But tell the truth, tell the truth.

They also want to join.

But no matter how hard they tried, they couldn't think of such an old stalk.

……

Ten minutes later, under the organization of Shen Yiyun and his two senior brothers, all the students participating in the training camp had gathered together, and Shen Yiyun would roll call and briefly describe the training process.

Except for Wu Shu, who was half-prostrated on the suitcase, and smirked from time to time, everyone else stood upright.

The content of this training camp is mainly experiments, a total of 4 days. On the morning of the fourth day, the experimental test will be conducted. Based on the theoretical test results of the preliminary competition, the top 13 will be selected to enter the provincial team and represent Jijing to participate in the National Chemistry Olympiad in early December. finals.

Students who sign up for the Golden Autumn Camp will stay for an extra day after the training camp to conduct an additional theoretical assessment.

It is worth mentioning that Zhou Yi, vice president of the School of Chemistry, will pay attention to each student throughout the process, and submit his recommendation to the Admissions Office based on his grades.

Li Zheng learned from everyone's chats that Zhou Yi is very well-known in the circle. Unlike other professors who live in seclusion, he is a scholar who focuses on teaching. For the past five years, the number of contestants signed by Ji Dahua Institute every year , Almost all of them are arranged by him alone.

Being able to obtain such great power shows that Zhou Yi has gained the trust of all the staff from top to bottom, from the inside to the outside.

Well, such an impartial and talented scholar will definitely not be careful about hating Porsche.

After understanding the general arrangement, the students put their luggage in the same place, and then each carried their shoulders on their backs, and came to the small auditorium of the Chemical Institute to participate in the opening ceremony of the training camp.

Although there were only about 50 people in the entire auditorium, Zhou Yi still received thunderous applause as soon as he took the stage.

"Come into a ring! Make a big ring"

"Teacher Zhou, I want to form a ring!"

Zhou Yi himself was not very serious. Facing the voices of his classmates, he held the microphone and said with a smile: "Okay, okay, don't worry, after four days, I will make you a ring. If you don't, I will be a ring."

In a harmonious atmosphere, Zhou Yi was completely out of script, talking like a walk on stage.

"Let me tell you a real joke first."

"Many students have experienced such a thought process—"

“[Xuehua Jingshi: My dream is the Academy of Evolution, winning the Nobel Prize.]”

"[After successfully entering the Chemical Academy: I can relax in the Chemical Academy, and just think about how to transfer to the Department every day.]"

Amidst the laughter, Zhou Yi didn't stop.

"In addition, there is a more realistic joke."

"We, Mr. Wei from Jida School of Mathematics, will greet people in the School of Mathematics like this in the first class of freshmen—"

“[The graduation rate of our college of mathematics has always been in the second-to-last position in the whole school, so you have to work hard to change this history, but don’t worry about the decline, because the last one must be the college of chemistry. 】

Amidst more laughter, Li Zheng sat alone and twisted his face forcibly, quite disdainfully.

Unexpectedly, there is still a series of cold jokes in Huayuan.

The dean is so cold, it's only natural for the senior sister.

However, Li Zheng didn't know that he had been targeted long ago.

"Hey!" Zhou Yi's eyes lit up, and he pouted at Li Zheng, "Student, judging from your expression, do you think my jokes are cold and not true enough?"

Li Zheng and the people around him looked around in a daze, trying to see who was so arrogant.

Zhou Yi smiled and said, "Don't look, it's you, the only student who doesn't wear glasses."

The goal was instantly clear.

Li Zheng struggled and raised his hand to touch his eye sockets, then looked to Ou Xingzhuo on the left, just wanting to borrow a pair of glasses to put them on.

Ou Xingzhuo immediately dodged.

At the same time, Li Zheng also felt the chill from the stage.

Looking at the smiling dean, Li Zheng's understanding of society became more mature.

I thought you were always a massive character.

Why...the mind is so small.

Didn't I just tell a joke and I didn't laugh!

Li Zheng hurriedly used his emotional intelligence, and laughed generously: "Haha, it's very funny, Mr. Zhou, it's so real hahaha."

Silent.

His hypocrisy is indignant.

Zhou Yi looked at Li Zheng and smiled like a fat baby.

"It doesn't matter. For students who are particularly outstanding in chemistry, these jokes are indeed untenable. In any case, I still appreciate your attitude. Young people have ambitions and there is nothing wrong with it." Zhou Yi raised his thick eyebrows and smiled, "In this case, I Speeches probably don't apply to you anymore, instead of wasting time, why not..."

He said and turned to look at Shen Yiyun: "Well, Xiao Shen, I happen to have a problem in my bag. You can use it for this classmate to do. The problem is very simple. After I finish talking, I will finish it."

Shen Yiyun, who was sitting in the front row, also stared at Zhou Yi frantically.

You abused the wrong person, Dean, this is not Ou Xingzhuo!

This kid is a good schoolboy!

People didn't regard you as a dragon ball!

However, Li Zheng was extremely honest, and he had already picked up his pencil case and got up.

Small-minded dean, although scary.

But he hit me with a question.

Dean, you hit the steel plate!

In this way, Li Zheng walked to the table next to the auditorium alone under the relieved eyes of all the members, and started to study the questions.

Shen Yiyun stood beside him, wanting to remind him, but was ordered by Zhou Yi to go to the teaching laboratory to prepare.

She could only wish you well, and left sadly.

Zhou Yi's speech continued, but there was only one voice in Li Zheng's mind——

Make a ring, make a big ring!

For Zhou Yi's question, Cheng Huan was right.

However, he just tried the question.

Just throw up.

The title is a substance called (+)-Nakadomarin A.

And a structure diagram is given.

It was a structural diagram composed of an unknown number of hexagons stacked together.

In addition, there are many strangely shaped chains on the edge.

The whole structure is like a rotten hive.

This is no longer a question of big rings and small rings.

It's a series of iron chains!

[First question: Please briefly describe how many rings there are in this type of alkaloid and how it is composed. 】

Seeing this question, let's look at the chain link again.

Li Zheng felt his head was about to crack.

Chapter 144 Yes, It's a Ring

Look down again.

[Second question: Retrosynthesis is currently being carried out by the cut-off method, please give the retrosynthesis analysis]

Li Zheng stared.

Only then did I understand.

This question is not a circle.

Instead, it loops in reverse.

cut ring.

It is necessary to cut an extremely complicated magic ring into several independent large rings, and then cut the large ring into small rings, and so on, until a sufficiently simple and common starting material is found.

Taking cooking as a metaphor, it is equivalent to throwing a cooked dish to the cook to taste, and let him reverse the recipe.

It's wonderful.

But this is already an organic question at the graduate level.

Icho international competitions may not necessarily be so deep.

Even Li Zheng, who was overprepared, panicked in the face of such a magic ring.

Of course, no matter how panicked you are, you will naturally be as excited as you are.

If it was Shi Yang, how would he feel about this question?

Thinking about it carefully, this magic ring is indeed terrifying.

But the knowledge of problem solving did not exceed the outline of the final.

Among them, the most critical "Organic Synthesis - Severing Method" and "Organic Synthesis Route Design", I have just read it, and I have occasionally discussed it with Shi Yang before.

In theory, I already have all the basic knowledge to understand this question.

However, in the face of this level of questions, there is too little experience and training.
