Shi Lei wanted to help, but Zhou Wen refused.

He drove him away on the grounds that he was not suitable for helping him.

Shi Lei is here, and he can't use his skills.

After applying the glue, start electrophoresis analysis.

In order to prevent errors, he strictly follows the operating procedures for each step, with ice operation, temperature, time and techniques, and strives for excellence. At the same time, the eyes of true vision are always open to prevent bacterial contamination.

After the electrophoresis machine is turned on, turn it back and extract the sample and place it on the slide, and observe it on the electron microscope.

After observation, no suspicious viruses were found in the sample tissue of the mutant aphids.

Although Zhou Wen already believed that he was not poisoned, he was not afraid of ten thousand, just afraid of what if.

He still insisted on doing a blood test for himself, but of course the result was nothing unexpected. Whether it was electron microscope observation or true vision, they were very healthy.

"very nice~"

Zhou Wen is very happy.

The last bit of grudge in my heart disappeared completely.

Next, start the DNA extraction work.

Proficiently dissect the rat, extract the bone marrow, rinse, counterweight, centrifuge, extract, and complete in one go.

Moreover, the dose extracted at one time is not 4 plants, but 7 plants, which is far from possible with ordinary biological organisms.

Next, start doing electron microscope observation.

In fact, theoretically speaking, there is no need to do electron microscope observation, because the true eye has seen the DNA extraction successful.

However, the system did not prompt the task to be completed, which means that the electron microscope observation step cannot be avoided.

Stain, centrifuge, extract, pipette, add fixative, then centrifuge, and then add fixative.

The function of "fixation solution" is to fix DNA and prevent the DNA from decomposing after centrifugation.

Finally, the slide is drawn and placed on the stage to observe electron microscope.

“perfect~”

When the task completion prompt came in my ears, Zhou Wen showed a happy smile on his face and looked at Timer. The whole process took 2 hours, which was simply fast. If Shi Lei and the others knew about it, their eyes would probably be shocked.

Just as he was planning to open the task panel, Professor Wang Huiyao, the instructor who had always seen the dragon, came in through the door.

Wang Huiyao is in his fifties, tall, white-faced and beardless, wearing a suit and tie. People who don’t know him think he is a business elite.

Seeing that Zhou Wen was the only one in the laboratory, Wang Huiyao said strangely: "Why are you the only one, and there are still people?"

Zhou Wen said: "Shi Lei and Lin Jiayi have just left, and nothing else has come."

Wang Huiyao nodded and said nothing.

It is a public thing that biology has no future. Students are unwilling to waste their limited energy in laboratories without technical content and can understand it, and it is difficult to blame anything.

His eyes circled around the laboratory and then he was about to leave.

He came to find Shi Lei. Since Shi Lei was not here, he did not need to stay.

But at this moment, Wang Huiyao saw the slide on the electron microscope stage, pointed at it and said, "Is this what you tested?"

Zhou Wen nodded, scratched his head and said, "Well, yes Professor Wang."

Wang Huiyao did not mention that novices were strictly prohibited from operating electron microscopes, and asked: "How are you learning?"

Wang Huiyao also asked casually. Undergraduates like Zhou Wen who have just arrived in the laboratory for a short time would be very good to be able to do electrophoresis analysis well. It is really hard to expect them to do electron microscopy observation.

It’s not how difficult it is for electron microscopy to observe itself, but mainly because of the previous processes, such as extraction, dyeing, centrifugation, etc., each step is likely to lead to the failure of extraction.

However, what Wang Huiyao didn't expect was that Zhou Wen actually pointed to the six DNA plants next to him and said, "I have learned it almost all, these are all observed by electron microscope."

"Oh?" Wang Huiyao was a little surprised, and was slightly surprised, "You did it?"

"Well, yes Professor Wang."

Wang Huiyao looked around and then remembered that Shi Lei and the others were not in the laboratory, "Your name is... Zhou Wen, right?"

"Um."

Wang Huiyao nodded slightly, but still didn't believe it. He has taught so many undergraduate interns, and few people can do a good job of electron microscope observation during the undergraduate stage.

He walked to the electron microscope and first looked at the electron microscope.

After confirming that the electron microscope was not damaged, he looked at the slides on the stage and asked, "How long did it take?"

Zhou Wen looked at the wall clock and it was already half past 6:30, "Uh... about 10 hours."

Zhou Wen deliberately made the time long.

Wang Huiyao didn't know that the six DNA samples were extracted from the bone marrow of the same white mouse. In his cognition, there were at least two or more groups.

That is to say, in the case of smooth sailing, a group averages 5 hours.

For an undergraduate, it is already very, very good, and even excellent.

Wang Huiyao sat down in front of the electron microscope, debugged the camera and began to observe.

A few seconds later, Wang Huiyao's face showed a slightly surprised look.

The DNA structure on the slide can be seen clearly.

Wang Huiyao raised his head, showed a smile on his face, and praised: "It's done well."

Zhou Wen said modestly: "It's all taught by Team Leader Shi Lei and others."

Wang Huiyao looked at him seriously.

He is quite tall and handsome, especially the momentum between his eyebrows, which is particularly strong, and has a sense of confidence that is rare in modern young people.

Wang Huiyao stood up and patted his shoulder, and asked with a smile: "I remember you haven't taken the postgraduate entrance examination yet. How about it? Are you interested in applying for my graduate school?"

Zhou Wen showed an awkward look on his face.

If it is another major, the professor will invite him in person, that would be a great deal of face.

But the creature...

Domestic graduate students can also do some difficult imitative experiments and help their supervisors do some very low things, including doctoral students. They will not have independent experiments at all, and studying for graduate school is basically a waste of time.

To put it bluntly, it is the cheap labor of the mentor.

Although this is better abroad, it is limited to good.

Because this is caused by the biological environment.

Biology is a research science. You must not only understand all the basic knowledge in the current biology discipline, but also understand all the knowledge you need to study in order to innovate.

This is really too difficult.

Seeing the expression on Zhou Wen's face, Wang Huiyao understood what he meant, and didn't say anything. After removing the smile on his face, he nodded and left.

Although he loves talent, he is not as good as applying cold P shares with a hot face.

Zhou Wen also "shushed" his tone. Although he was embarrassed, he was also helpless.

Compared to studying for a postgraduate degree, he hopes to go to a scientific research center or a large laboratory as an experimenter, so that he can learn more and allow him to conduct pharmaceutical experiments as soon as possible.

Standing on the spot and thinking about the next development for a while, Zhou Wen immediately called out the system when he thought of the task.

The prompt box on the attribute page is still there, [Will you submit the task immediately? Yes/No]

Select [Yes]

[Ding! Mission is completed. Rewards are now paid... Congratulations on getting 200 subject experience and 300 points.]

【Will you unbox it now? Yes/No】

Seeing the words on the prompt box, Zhou Wen was excited again and murmured: "Please, God, just give me 1,000 yuan...or whatever is worth a little money, I won't choose."

He is so poor that he is almost selling blood.

Nowadays, the price is expensive. It costs 10 yuan to go out to eat egg fried rice. I don’t dare to order takeout because it requires a delivery fee.

He even dared not look at fruits or something, because he was afraid that he would shed tears of poverty.

With a hundred thousand expectations, Zhou Wen chose [Yes]

The black wooden texture treasure chest popped out, with complex patterns engraved on it, and an ancient key was still floating next to it.

Silently recite in my heart [Open]

The key was inserted into the keyhole, and after rotating, the box opened, and a spherical object shining with crimson appeared.

Before he could see what it was, a prompt box popped up just like last night.

【Congratulations, you will get pure natural pollution-free apple × 10…】
Chapter completed!
