Tu Xian didn't say how long he stayed in Xibao Middle School. Yang Rui didn't ask, so he found a teacher's dormitory for him and lived in the canteen. He greeted the master of the canteen and stayed in the laboratory every day.

The laboratory is soaked, and experiments are similar to cooking. Small experiments are like cooking at home. You can watch people spin continuously inside, and the meals and experiments are done. Medium experiments are like the kitchen of a restaurant. It is best to have someone helper. The chef's workload has dropped and he is waiting from time to time.

Even if the experiment Yang Rui is doing now is a medium-sized experiment, it is difficult to carry out without an assistant. However, if there is an assistant, there is a lot of time to be free, which is a state of being idle when you are idle when you are free and busy when you are busy.

Whenever he is free, Yang Rui is accustomed to reading papers and books in his mind. Compared with the knowledge he could obtain in the 1980s, reviewing the content of later generations now will have many benefits.

At least, Yang Rui felt that if he had just studied for 30 years, he would not have to be afraid of anything by 2014.

In any era, people who can master comprehensive knowledge cannot be underestimated.

Anyone who can study for 30 years should stand at a high level even if he cannot reach the top of the pyramid.

Of course, in the eyes of others, Yang Rui seemed a little strange, because in their eyes, Yang Rui was just staring blankly. The most amazing thing was that after he was staring blankly for a long time, he often jumped up, either writing a bunch of things or doing several verification experiments.

Tu Xian could understand that Yang Rui probably simulated something in his mind.

However, this understanding is only based on superficial understanding. After all, how complicated and difficult is it to simulate so many things and so many experiments in the head?

Perhaps he wanted to understand Yang Rui's working methods, or perhaps he wanted to learn more about plant extraction, so Tu Xian stayed in Xibao Middle School.

He didn't talk about going back to work, and Yang Rui didn't care about having another free labor.

In fact, he also wanted to use this good labor for a while.

"Let's turn on the centrifuge, let's change two variables today and do another set of experiments." Yang Rui raised his head and ordered, and Tu Xian went to work happily.

He has received several years of professional training, and his experimental level needs to be said. What is rare is that he can conduct experiments alone and replace Yang Rui's work or supervision, which saves Yang Rui a lot of effort.

Yao Yue and Lu Zhi, who had just come from Hedong University today and were trying to help Yang Rui, looked at Tu Xian curiously, a little unable to let go.

Tu Xian looks like a teacher, and it is still a bit shocking in front of the students.

Tu Xian also saw that they were students, so he didn't care, and his hands were not slow at all.

After a while, the experiment was completed. Tu Xian took the responsibility of his assistant and gave up his position and said, "It's time to start."

"You can do it." Yang Rui pointed his chin.

"Oh... OK." Tu Xian hesitated for a moment and said, "You two cooperate with me, you are the one who is braided. You are also responsible for the experimental record. Now is the 15th group of experiments for extracting loniol in waste tobacco leaves. Eight parts of 200 grams of tobacco leaves have been crushed. One and 16.5 times the weight of acetonone solvent was added to the soaking time for 20 hours. After filtering and distilling the acetonone, the residue was added to the saponified liquid..."

He looked at his watch and said, "Now add different saponifications to 8 parts of the residue."

Yao Yue and Lu Zhi followed his instructions and began to accurately weigh different solutions.

This work is cumbersome and meticulous, and there is nothing special about it. Tu Xian looked around the laboratory table and confirmed that all the conditions were normal. He turned around and stood next to Yang Rui, as if chatting, and said: "Your laboratory is sponsored by Jielikang. What should I do after you go to college?"

"Where I go, the laboratory will go wherever I go." Yang Rui solved the problem that Tu Xian carefully considered in one sentence.

Tu Xian frowned and said, "It is not easy to transfer experimental equipment, it costs a lot of money."

"I know."

"Jielikang is willing to offer? So many experimental equipment will cost thousands of yuan, and maybe it will be damaged." The disassembled experimental equipment is different from the newly-factored equipment. On the other hand, some experimental equipment needs to be readjusted every time, or fixed, or fixed, etc. The manufacturer usually provides the first installation and debugging service, but it is impossible to provide installation and debugging services every time. It would be fine if it was domestic equipment. Foreign equipment often sends an after-sales engineer to come, which would cost thousands of dollars. It is really not easy.

Yang Rui nodded. He paid the money himself, but there was no need to explain it to Tu Xian. When purchasing laboratory equipment, he considered the transfer issue. As long as the packaging and transportation issues were solved, it would not cost too much money as Tu Xian imagined.

Tu Xian smacked his tongue and asked again: "Where are you going?"

Yang Rui glanced at him and said with a smile: "It's not sure yet, but the laboratory may have an expansion at that time."

“Will it expand?”

"I will buy large-scale instruments such as electron microscopes, and the scale will also increase." Yang Rui looked around for a week and then said, "At that time, I will ask Teacher Tu for more help."

"Oh, ought, ought." Tu Xian replied immediately, almost not thinking much in his mind.

Yang Rui smiled slightly, and what he wanted was the current effect.

At Xibao Middle School, he had Wei Zhenxue as his main experimental assistant. If he arrived at a new location and searched slowly, it would be too late. Moreover, the new semester of university will definitely be relatively busy, and Yang Rui also needs a university teacher to help.

Therefore, when he saw Tu Xian's letter that day, Yang Rui immediately replied, and was not hesitant to show the most advanced technology in China.

Tu Xian came to Xibao Middle School. In a few days, he was indeed trapped in the laboratory and could not extricate himself.

It is completely a personal laboratory, and all experimental instruments are waiting for you to use, rather than people waiting for experimental instruments. This kind of sourness and pleasure is probably difficult to understand if it is not a researcher.

If you do a comparison, doing an experiment in an ordinary university laboratory is like watching a movie for ten minutes, and you will be called out immediately, and you will wait for another 40 minutes, and you will be called out again for ten minutes.

In a personal laboratory, the experimenter can arrange time and instruments to the fullest, and the experimental materials can be left in the laboratory without having to move them around. What’s even more difficult is that there are always experimental assistants in Yang Rui’s laboratory.

Tu Xian is a lecturer in school. No matter how the paper is written, he is not qualified to be an assistant. Even when he is an associate professor, he is not bound to have an assistant. Now he has enjoyed the assistant who doesn’t have money in advance, so he naturally feels relaxed and happy in Yang Rui’s laboratory.

The most rare thing is that Yang Rui allowed him to design experiments and write papers by himself. In other words, after completing the experiments arranged by Yang Rui for him, Yang Rui did not interfere with what experiments Tu Xian wanted to do, which was the same as Wei Zhenxue's treatment.

Tu Xian stayed for a few days and didn't go back, mainly because of this temptation.

"If you can go to Beijing, I guess it will be much more convenient for doing research." Tu Xian was thinking about taking Yang Rui to Beijing, so he would be much more convenient for him.

Yang Rui smiled and said, "The management of universities in Beijing will be stricter."

"Some are stricter, some are not. No matter which one, you have good studies and grades, and you will be relaxed in management, otherwise you will be strict, right?" Tu Xian showed some of the teacher's momentum, and then turned his tone quickly: "Of course, if you have any inconvenience, it is quite easy to ask me for help. I know a lot of people in Beijing."

"At that time, maybe I really want to ask Teacher Tu."

"Ah! You're welcome, you're welcome. You should have something you don't understand. Just ask me directly. Well, do you have any questions about your exam? The scores in universities in Beijing are not low." Tu Xian was flattered and began to worry that Yang Rui was biased.

It is normal for students in the 1980s to be biased in subject matter. It is obvious that it happens frequently. The first thing is the quality of the teacher. If a normal student is just starting to study physics and chemistry in junior high school, he will encounter a physics teacher and chemistry teacher who have just graduated from a technical secondary school and entered the school through the back door. It is very difficult to think about subject matter without biasing in subject matter.

Even if the restrictions are lifted and ordinary secondary school students are used to teach junior high school students, there will be no good results. It will be even worse for using secondary school students to teach high school students. It is simply tragic, but such things happen every day in China.

Tu Xian looked at Xibao Middle School and thought of Yang Rui's identity as a repeat student, and he had deep doubts about Yang Rui's academic performance.

In such a mountain valley, being able to write English papers and perform biological experiments with great talent is already a god-like level, so we can't expect him to do more.

However, if the subject is serious, the total score will still be greatly affected. The three courses in biology, chemistry and English are only 250 points.

Yang Rui gave Tu Xian a smile and said, "My grades are OK. If nothing unexpected happens, it shouldn't be delayed."

Tu Xian remained worried and said, "It is best to study in an undergraduate school. There is a big difference between undergraduate and junior college. Just talk about the experimental conditions. In Beijing, it is okay to collect several laboratories like you. Although it is scattered in different departments of the school, because there are funding every year, the speed of building laboratories is also accelerating. Colleges are not allowed. Only key departments have one or two laboratories that are acceptable, and everyone is rushing to use them. In addition, there are obvious differences in accommodation conditions, classrooms, libraries, and campus areas."

Of course it is obvious that the levels of different schools are clearly defined by the state in the form of documents. The total funding of junior colleges in China is not as high as that of top universities in Beijing, but the number of students varies by more than a hundred times. The average treatment each student enjoys is naturally completely different.

Yang Rui nodded and said to Tu Xian again: "I will definitely be able to get into college."

"You can't take it lightly, you must take it seriously. The college entrance examination is very difficult. I said, it's the college entrance examination soon. If you don't take a break for a while, you can review it carefully first." Tu Xian missed Yang Rui too much.

Liu Shan, who was doing the experiment, burst out laughing and said, "Yang Rui is the first in the preliminary exam."

"Pre-examination is a pre-examination..." Tu Xian looked at Liu Shan and Lu Zhi's expressions that were wrong, stopped with a whisper, and asked, "Where is the first in the pre-examination?"

"Hedong Province's pre-examination first, and its total score may also be the first in the country." Lu Zhi rushed to say it and said: "The pre-examination is a ranking within the province, and it is not a ranking in the country."

Now that there is no Internet, they can't ask about the pre-exam scores in other provinces.

Tu Xian was extremely surprised and felt regretful, "That's what we can do, we can't be alumni."
