The other party changed to a "polite request", but Gu Zhe couldn't just fight back directly, which made him look ungraceful.

Of course, if Gu Zhe is willing to take action, it will be very easy to crush the other party.

However, Gu Zhe, who was a lawyer in his previous life, believed in a creed: no referees, no debate.

Whether it is a lawyer’s court debate or a scientific research and academic defense, it is necessary to have a more authoritative third party present to be valuable.

Otherwise, only the two parties with conflicts of interest will just waste time and nonsense.

In his opinion, what is Feng Tao? Even the teacher who supervises the scene is nothing, and he won't make any profit.

Fortunately, the two of them had a little dispute for a while, and more and more people gathered in the corridor outside the laboratory. Other candidates who came to adapt to the venue also took some rest and came to watch the fun.

Because the congestion in the corridor affected the passage, within a few minutes, a passing professor of the Academy of Chemical Sciences finally caused dissatisfaction.

"What are you watching in the experimental building? Pay attention to discipline and everything is gone!" A young square-faced professor with a fierce face couldn't help but scold him.

"It's Professor Zheng Jian and Zheng! The academic leader in the field of polymer materials! Don't offend him. If you want to achieve results in chemistry in the future, you have to mess with him." Some candidates whispered and immediately disbanded.

Seeing this, the supervisor in the laboratory quickly told Feng Tao to stop making trouble, and rushed to the corridor in two or three steps to explain to the professor.

Zheng Jian didn't give him face and directly scolded: "Xiao Wu, you are the same. You can't even manage a laboratory well. No wonder you have been assistant coaching. What's the situation?"

Teaching assistant Xiao Wu: "There are a few students who practice experiments discussing issues, which attracts other students preparing for the exam to watch, and there is nothing else."

Professor Zheng understood the causes and consequences and immediately understood them. However, he didn't like people who relied on policy dividends to make benefits, so he walked up to Gu Zhe and said:

"Then are you sure? If you don't want to practice this question, you whispered to me, I'll let them all go. If you are willing, I won't let you suffer any losses.

This kind of skill was not possible, but you can barely see the solidity of the basic skills of the experiment. You Zhenyang Middle School are also being taken advantage of by the way. If you perform better, it will be easier for the above to explain it."

Gu Zhe understood immediately:

Because last year's competition was the first time that the "recommended student consolation prize quota" system was implemented, so there must be some people who were dissatisfied. Both sides had the power to operate behind it, and they wanted to catch the mistakes of another faction's viewpoint.

If the victims of that reform performed particularly well, such as Feng Tao in front of him, then another faction would attack on various occasions either openly or secretly: Look, because the reformists who are mixed with the reformists blindly seek stability, ignore fairness and talent selection effects, and finally "there are no wicked people" in the end.

On the contrary, if the beneficiary of the reform, such as Zhang Ming, who was recommended by Zhenyang Middle School last year, performed better than the other people who won the first prize in the province by relying on their real strength, then the reformists can set a typical example and speak to him.

Unfortunately, Zhang Ming's strength is indeed not comparable to the other three provincial first prizes, and he can't compete for this tone.

At this time, once someone notices Gu Zhe's positioning, they may look forward to his performance. If Gu Zhe performs well and has a good academic future in the future, the reformists can also say:

"Other high schools in the province also have top talents in this area. At the beginning, they were only beaten by the ugly monopoly of Ark No. 2 Middle School and became autistic. This led to insufficient competition and burying talents. "There are wise men." After the reform, these people saw hope, so they worked hard and had the potential to grow up, becoming 'no wise men'."

Professor Zheng, who was passing by, did not care about the twilight factions in the political and educational system. But after all, this was the first year of reform. It was a turbulent past and it was difficult for him to not hear it. When he saw it, he quickly cut the mess to remind Gu Zhe and let him do it by himself.

Anyway, people are in the world, so it is impossible to quit.

Gu Zhe didn't care at first, he was sure to crush Feng Tao. He just felt that he didn't need to prove anything to the minions. Now he has attracted the big guys to watch, and there are so many benefits behind it, so it's nothing to take the opportunity to show it.

As a rebirth, Gu Zhe also knew that Professor Zheng was a figure in the field of polymer materials in China in the later generations. He was transferred to a provincial university in another province to be the president more than ten years later.

Gu Zhe is still a little slight person now. It is nothing wrong to sell the other party’s face to make him familiar with him.

He glanced at Feng Tao put it on the seat next to him, and slightly opened a small bag. He had already made a plan in his mind and agreed openly:

"Since Professor Zheng also thinks this kind of exercise is helpful for understanding basic skills, I'll give it a try."

After Gu Zhe finished speaking, Zheng Jian gave Xiao Wu an instruction: "Go to the office to find me in a while and tell me the result."

Then he left. He was very busy and had no time to stand by and watch the students do the experiment for half an hour.

The other teachers and students were finally able to watch the corridor openly. After such a fuss, several supervisors from the laboratory nearby also came.

Gu Zhe started operating without any panic.

In his mind, he passed the density table of all common solutions and the mutual repulsion in his mind. The density of water is 1, the octane of gasoline is 0.7, and the pentane of the lightest liquid of alkane is 0.62.

(Note: The A, B, B, and B, and B, are all gas at room temperature. Pentane is actually very limiting, and the boiling point is 36 degrees. The competition time in the book is winter, so it is ensured that it is a liquid, and it may evaporate in summer)

The difficulty of making a mix of multiple layers of water and oil is that water-based inorganic solutions are often more dense than solutions composed of gasoline and other organic matters, so it is difficult to have oil on the water and water on the oil, as clear as a layer by layer.

However, alcohol can be used as a medium. The ethyl group in ethanol is a lipophilic group and the hydroxyl group is a hydrophilic group. If the application is done properly, and combined with a series of mysterious solutes to adjust the solution density, there is still a lot of room for operation.

This is also the underlying physical and chemical principle of why alcoholic beverages can be played with so many cocktails.

Of course, the difficulty here is not clear. As long as an outsider knows that it is difficult, it is fine. If you are not careful, it will easily lead to water, oil, and alcohol being precipitated and layered.

In short, Gu Zhe finished his undergraduate degree in materials chemistry in his previous life and had several years of scientific research. His accumulation and depth of understanding are obviously far from comparable to Feng Tao.

With rich experience, Gu Mo thought about the operation in his heart, he made a configuration operation and then injected layers of liquid into the separating funnel along the glass rod.

The density of each layer ranges from 1.33 grams (saturated concentrated brine) to 0.62 grams (pentan-based solution). The density difference for almost every 0.1 grams is different. Gu Mo can steadily make a mutually repulsive layering solution. Finally, he actually made a "nine-layer cocktail" in the separating funnel.

In order to facilitate the teacher's observation, he thoughtfully added appropriate colorant to each layer when configuring it. Then, he injected nine layers of water and oil separation solutions of different colors into nine beakers. Each cup was very accurate and no other colors were mixed.

When Gu Zhe finished the final operation, several assistants present were quite surprised, and some of them thought they could not do this.

Those students who had never seen the world had even opened their mouths so much that they could stuff duck eggs, and they didn't dare to breathe loudly for fear of affecting Gu Mo's operations.

Even if you are an outsider, you can count and count. It is still obvious that the difference between being divided into nine layers and five layers is definitely much stronger. The former has definitely a much stronger grasp of density difference and mutual solubility.

Amid everyone's amazement, Xiao Wu's assistant coach was about to go to the office to find an opportunity to report what he saw here. Feng Tao looked ashamed and wanted to pack his bag.

But Gu Zhe is an old world after all, so he had already observed it clearly. He blocked Feng Tao's hand and sneered:

"It's so calculating. There's a digital camera. If you win, record it. Maybe it's useful in some occasions in the future. If I win, I will delete the SD card directly.

This is treating me as a rabbit, and you are a turtle yourself. The rabbit has already lost the moment he accepts the challenge, and it is not good for him to win."

After all, Gu Zhe has been a lawyer for many years, so he has already seen this trick of secretly collecting evidence just now.

What's more, the digital camera in 2002 was so stupid, big, black and thick, and it had to be opened a large gap in the bag to prevent the camera from blocking the camera. Feng Tao could not get a spy-level miniature camera, so it would not be directly seen through.

Gu Zhe was so clear in his heart: That guy just wanted to get more information without any problems. Maybe if there was any serious information, he would be able to complain to the media and criticize last year's new policy for recommendation.

As soon as Gu Zhe said this, the supervisor and other students were naturally very unhappy. How could he do this?

Although the matter in the laboratory is not personal privacy, and the law in 2002 is not very clear about the protection of this aspect, their moral intuition makes them feel that this kind of filming is not very authentic.

Xiao Wu’s assistant negotiated sternly and asked him to hand over the SD card involved, but Feng Tao also admitted that he had failed. Not touching his camera was considered to protect private property and was more restrained.

Then Xiao Wu took the card and took a few students to Professor Zheng's office to give him a simple reward.

There are several other chemistry professors and associate professors in the office. Some of them happened to be drinking tea, so they came to listen to interesting stories together.

The professors naturally would not be surprised, but just nodded slightly: "This year's freshmen seem to have good experimental results. Pay attention to the formal exams when the time comes."

Professor Zheng himself actually didn't want to ask more, but after all, he asked Xiao Wu's assistant to report. Out of politeness, he asked Gu Zhe a few more questions, wanting him to talk about his experience in practicing experiments, but why he was so familiar with these useless operations.

Gu Zhe is naturally a type of person who is ruthless and doesn’t talk much, so he said directly:

"Maybe I like to think more and have a thorough understanding of the underlying principles. Actually, I don't like to practice fancy operations, but if I don't want to do too much, I can understand the pain points and solve the problems once and for all."

"Fix it once and for all?" Professor Zheng was really interested in Gu Che after hearing this. He put down his pen, "How to solve it once and for all? What can I solve it?"

Gu Zhe stopped talking, took the pen that Professor Zheng put down and wrote two strings of numbers.

Professor Zheng was stunned: "What is this?"

Gu Zhe put the pen: "Several utility model acceptance numbers can help cocktail bartenders add interlayers to density layered wines. This is also a bit similar to the experimental operations I practiced today.

This is the value of me practicing these useless operations - to fight myself, thoroughly imagine the underlying principles, and then invent something to simplify other people's operations."

Professor Zheng finally felt awe: "You have just graduated from high school and you actually have a patent in your name? You are so terrifying."

As a professor, there are many patents under his name, and at least several are "invention" level, which are much higher than Gu Zhe's "utilitarian model". However, if you have patents after graduating from high school, it is undoubtedly worthy of attention and training.

Professor Zheng had already had the idea of ​​cherishing talent in his heart. When Gu Zhe was admitted to Zhu Kezhen College, he would give him some advice.

Gu Zhe clarified without being humble and arrogant: "It cannot be considered that there is a patent under his name. This is just an acceptance number, not an authorization number. It only means that the State Administration of Knowledge has begun to review my content, and it has not been reviewed yet."

Professor Zheng nodded: "Young people are right to be more rigorous. Well, you are the candidates who have been enrolled in the exam these days, and you will take the exam well. I hope you can study chemistry well after entering Zhu Kezhen College, study graduate school all the way, and make some achievements."

...

The familiar venue for the last day before the exam ended in this little episode.

After Gu Zhe returned to the hotel to rest, other candidates who practice chemistry were still telling his legend, thinking that his operation was definitely not something that high school students who had only practiced for two years could accumulate.

The next morning, the official additional examination was for the special admissions of chemistry. However, after the twists and turns of the previous day, when the official exam date was on, there was nothing new that was worthy of writing.

Any classmates who know Gu Zhe have improved their expectations for his strength, and it would not be too strange to know that he was doing well in the exam in the end.

The content of the exam was written in the morning, and I used the Global Finals test papers I used in the Netherlands yesterday to save trouble. However, I was not afraid of leaking the questions. First, the time was too short, and second, the subsequent experiments could not be faked, and even if the questions were leaked, there was no time to prepare.

If someone has a very high score in the theory part but the experiment is very poor, then it may require a review. If both are good, it doesn't matter.

Because the chemistry exam was only recruited by a few candidates. Zhu Kezhen College had only more than 200 students in one class, and 60 people were from mathematics, physics and chemistry. Previously, the competition was recommended and other independent enrollment was recommended, and 40 places had been used for each major.

If you recruit more after the college entrance examination, there are only 20 people in each direction, and you have to share them with so many provinces. The Donghai Province can only leave only single digits. For this kind of exam to recruit a few people, it is not cost-effective to give a set of papers carefully.

Gu Zhe repeatedly did the Global Finals questions of that year in his previous life. Naturally, he was familiar with the written test and even handed in advance. However, the written test part did not mark the paper immediately, so the invigilator could not immediately see his level.

However, the experimental examination part in the afternoon was real and immediate. Gu Zhe was as fierce as a tiger in his operation, completing the "preparation of polypeptides in an amino acid environment with protective groups" perfectly.

The second part of the experiment is to take the peptide you just made, analyze and verify the purity, and write an analysis report. If it is not pure enough, analyze the reasons.

The second part does not mean that the better the analysis data, the higher the score, but the more in line with the actual score, the higher the score. But there is no way. Gu Zhe completed the first step too well, and the quality of the product was too high, so that there was nothing to write in the second stage analysis report.

So, the experimental part was almost an hour earlier than others. I was so successful. You asked me to analyze the causes of impurity and lessons of failure. What can we write about? Isn’t it better to just say a few simple sentences and a conclusion?

At the end of that day, the teachers in charge of the invigilator knew that Gu Zhe had almost scored the experimental part. With this single item alone, he had already been sure to recruit Zhu Kezhen Academy.

PS: There are many technical details today, and I have tried to understand them as easily as possible. Some places even sacrifice accuracy. Considering that some book friends don’t like to read technology, I added more than 7,000 words today and passed the plot of the contestants’ exam within one day.
Chapter completed!
