"Oh?" Li Zheng looked at her reluctance, and immediately got excited. "Don't be obsessed with brother, brother is just a legend~"
"Oops, it's embarrassing to die." Wu Shu finally couldn't help it, bending over and laughing gigglingly, "Stop, stop hahaha."
How is it possible, just like just learning to tickle, how is it possible to stop.
"Greater my brother." Li Zheng rubbed his hands.
"Haha, you are enough."
"Brother eats not noodles, but loneliness."
"Okay, please, I'm going to die haha!"
Li Zheng is very happy to play with the old terrier, but he does not know...
More than 40 men with flat-headed glasses who came to gather, had already stared at each other, eyes full of blood.
The only girl in the whole camp, the official physics queen recognized by the whole school...
What happened to your kid?
The Queen is dead!
But there is one saying one, telling the truth.
They also want to join.
But no matter how hard they tried, they couldn't think of such an old terrier.
...
Ten minutes later, under the organization of Shen Yiyun and his two brothers, all the students who participated in the training have gathered together. Shen Yiyun will call the names and briefly describe the training process.
Except for Wu Shu lying prostrately on the suitcase and giggling from time to time, everyone else stood upright.
The content of this training session is mainly based on experiments, a total of 4 days. On the morning of the fourth day, an experimental test will be conducted. Based on the theoretical test results of the preliminary rounds, the top 13 ranked provincial teams will be selected to represent Ji Jing in the National Chemistry Olympics in early December. finals.
Students who sign up for Jinqiuying will stay for an extra day after the training to conduct additional theoretical assessments.
It is worth mentioning that Zhou Yi, deputy dean of the Institute of Chemical Engineering, will pay attention to every student throughout the process, combine his grades, and submit his recommendation to the admissions office.
Li Zheng learned from everyone's chats that Zhou Yi is very famous in the circle. Unlike other professors who lived in a short time, he is a scholar who focuses on teaching. Over the past five years, this year, Jixian Dahua Institute has signed a number of contestants. , Almost all 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 and from the inside to the outside.
Well, such a fair and talented scholar will not be careful to remember things that hate Porsche.
After understanding the general arrangement, the students put their luggage in a unified location, and then each carried their shoulders to the small hall of the Chinese Academy of Chemistry to participate in the training camp.
Although the entire auditorium is only 50 people, Zhou Yigang just got on stage and still got thunderous applause.
"Form a ring! Form a big ring"
"Teacher Zhou, I want to form a loop!"
Zhou Yi himself was not very serious, facing the voices of the classmates, holding the microphone and laughing: "Okay, okay, don't worry, after four days, I will wrap you up, you will not ring up, I will ring up."
In a harmonious atmosphere, Zhou Yi completely unpublished the manuscript and talked like a walk on the stage.
"Tell you a real paragraph first."
"Many classmates have gone through this thought process--"
"【When learning to compete: My dream is the Academy of Evolution, won the Nobel Prize.】"
"[After successfully entering the chemical institute: I can relax in the chemical institute, and I just think about how to change the system every day.]"
In the laughter, Zhou Yi did not stop.
"In addition, there is a more real paragraph."
"We, Teacher Wei from the Jishu College of Mathematics, the first class of freshmen, will greet the people of the College of Mathematics like this--"
"[The graduation rate of our number colleges has always been the second lowest in the school, so you have to work hard to change this history, but don’t worry about the decline, because the penultimate one must be the chemical institute.]
In more laughter, Li Zheng sat arrogantly, forcibly twisting his face, quite disdainful.
Unexpectedly, the Institute's cold joke was still a series.
The dean is so cold that the school sister is taken for granted.
However, Li Zheng did not know that he had long been stared at.
"Eh!" Zhou Yi's eyes lit up, and Li Nu made a mouthful. "This classmate, from your expression, do you think my joke is cold and not real enough?"
Li Zheng looked around blankly with the people around him, trying to see who was so arrogant.
Zhou Yi said with a smile: "Don't read it, it's you, the only classmate who doesn't wear glasses."
The goal was instantly clear.
Li Zheng struggled to raise his hand and touched his eyes, and then looked at Ou Xingzhuo on the left, just want to borrow glasses to put on.
Ou Xingzhuo immediately hid.
At the same time, Li Zheng also felt the chill from the stage.
Looking at the dean Xiaoyingying, Li Zheng's cognition of society has become more mature.
I thought you were always a huge figure.
Why...the heart is so small.
Didn’t I just tell a joke?
Li Zheng was busy using EQ, and just laughed generously: "Ha ha, it's funny, Teacher Zhou, it's too real ha ha ha."
The raven was silent.
His hypocrites were angry.
Zhou Yi looked at Li Zheng and smiled more and more like a fat doll.
"It doesn't matter, these paragraphs are not true for the students who are exceptional in chemistry. In any case, I still appreciate your attitude. The young people are aspiring and have no problems." Zhou Yi smiled with a deep brow, "Since this is the case, I am The speech is probably not applicable to you anymore. Rather than delaying time, it is better..."
He said to look at Shen Yiyun: "In this way, Xiao Shen, I just had a question in your bag. You used it to do it for this classmate. The question is very simple. When I finished speaking, I almost finished it."
Sitting in the front row well, Shen Yiyun also stared, mad at Zhou Yi to wink.
The wrong person has been abused, dean, this is not Ou Xingzhuo!
This child is a good student!
People didn't take you as a dragon ball!
However, Li Zheng is very honest, and has picked up the pencil case and got up.
Be careful, Dean, although terrible.
But the question hit me.
Dean, you hit the steel plate!
In this way, Li Zheng walked alone to the table next to the auditorium under the eyes of all the members in relief, and began to brush questions.
Shen Yiyun stood beside him and wanted to remind him, but was ordered by Zhou Yi to go to the teaching laboratory to prepare.
She can only say one word to wish you peace, and left.
Zhou Yi's speech continued, but there was only one voice left in Li Zheng's mind—
Form a ring, become a big ring!
Zhou Yi's question is right in a circle.
However, he just tried the question.
Just vomited.
The title is a substance named (+)-NakadomarinA.
And gives the structure diagram.
It is a structural picture that I do not know how many hexagons are stacked together.
In addition, there are many strange-shaped chains on the edges.
The whole structure is like a rotten honeycomb.
This is no longer a problem with big rings and small rings.
It's a chain of chains!
[First question: Please briefly describe how many rings are in this type of alkaloid and how they are composed. 】
Seeing this problem, look at the chain of chains again.
Li Zheng felt that his brain was about to crack.
