It's good to have momentum, but momentum doesn't solve anything.

For example, Li Zheng's group of people blocked in front of the laboratory door, and no matter how powerful they were, they couldn't get in.

Although it was already seven o'clock, a group of people inside were still unhurriedly finishing the operation in front of the computer on the operating table.

Because it was a relatively private and isolated environment, even people outside of their conversations could hear some of it.

"Hurry up, you guys, the next group is waiting. ”

"Huh, is there anyone else here here?"

"Dean Zhou arranged it. ”

“...... It's strange, Zhou Yi won't be taking on private work, right?"

"You can't talk nonsense. ”

"I seem to have heard Mr. Deng say that a great freshman from Yingpei found Dean Zhou and said that he wanted to do structural analysis, and Dean Zhou directly took this matter down and was unreasonable. ”

"Freshman?"

"Freshman year. ”

"This resource is given, I'm afraid it's related to Dean Zhou, right?"

"Either it's a big man in the family, anyway, the dean and Mr. Deng have also been approved all the way, and they are very low-key, so they don't say anything about it. ”

"In that case...... Do we want to make a backup of the data we just just made, and don't break them? ”

"Okay, okay, hurry, I'll guide them through the operation. ”

"Then Brother Liu must keep an eye on it, our chemical institute is just this one, don't spoil them. ”

"You're talking a lot of nonsense!"

Outside the door, everyone heard this, and their emotions were generally stable.

Only Lin Moming is still too young.

"Isn't it just an electron microscope, what's so remarkable, I can afford it in a few more years. Lin Moming scolded secretly, "Look at how I stare at them for a while." ”

"Well, it's all human. Li Zheng said indifferently, "We are special, we have to get used to being misunderstood, and we have to get used to being praised in the future, it's not that we have a good temper, it's just that those voices are too cheap and redundant, and we don't deserve to deal with them one by one." ”

As soon as she said this, Lin Moming's anger immediately calmed down.

Or to put it another way. Chang Keqing rubbed Lin Moming's head and said, "Don't be happy with things, don't be sad with yourself." ”

"Ahhh......h ”

"Spiritual practice? That can indeed make you more calm. Mo Nian only moved his five fingers repeatedly, looking at the gate level, "But the real calmness still comes from the confidence in strength, just like Li Zheng said, their words are not worthy of influencing me at all, I just want to put the planned things into practice quickly." ”

"Me too, empathize. The leader patted Mo Nian and also looked at the door, "I really want to dismantle a few parts and go back...... I'm just going to be, don't look at me like that...... Anyway, you have to get the monitoring done first, no. ”

As Shi Yang, he thought that he was peculiar enough, but when he heard this, he gradually felt that he couldn't hold it down.

"Brother......" Shi Yang swallowed and spat at Li Zheng's ear, "Our teammates...... Except for that long-legged big sister...... The others don't look like college students......"

"Don't panic, I have the confidence, and you'll understand when you do it. ”

"Okay......"

As he spoke, the door to the laboratory finally opened.

The three graduate student-looking seniors walked out one after another, looking at the group with a smile at first.

But soon, I couldn't laugh anymore.

This group of people ranges in height from 1.5 to 1.9 meters, and everything from muscular hunks to doll mascots.

Such a configuration does not look like a research at all.

It's like going to the next dungeon.

The tactics of the thief and the support are all here!

There is only one Shi Yang who is out of place......

Let's just think he's a slime.

Just as they walked slowly with vain steps and staring eyes.

A viscous exclamation suddenly came from behind.

"Li Zheng?!"

Follow the prestige.

Appeared, female slime!

Li Zheng was also stunned: "Although it is almost unrecognizable, it can grow to this size...... Senior Sister Shen?"

"Rub!" Shen Yiyun scolded sideways, and rushed over, "Who should I be, why did you go to Yingpei?"

"Hey, it's the same everywhere. Li Zheng then turned around and introduced, "This is Shen Yiyun, a senior sister in the third year of the Academy of Chemistry, and my experiment was taught by her." ”

Several people shook hands and recognized each other one by one.

When he recognized Shi Yang, his outstretched little fat hand was slapped away by another fat hand.

"What are you messing with!"

"Hehe~" Shi Yang scratched his head and smirked, "We haven't seen each other for a long time, shake it." ”

"If I don't shake it with you, your face is the face that you must not wash your hands after going to the toilet. ”

“...... Is there any basis for this?" Shi Yang immediately pointed to Li Zheng, "He didn't wash it just after he finished it." ”

"Hey, it doesn't matter if he washes it or not. ”

“......”

Shen Yiyun shook it around, and he was about to turn around.

was pulled by Li Zheng, coughed again, and pointed downward.

Shen Yiyun found out at this time.

It turned out that there was a little girl below who was raising her hand expectantly.

"Wow......" Shen Yiyun squatted down in shock, "It's so cute, like a doll." ”

Lin Moming's face changed instantly: "Okay, I know." ”

Li Zheng hurriedly explained: "This is Lin Moming, our official team member. ”

"Ah?ah?" Shen Yiyun looked back and forth many times before confirming that Li Zheng was serious, and then put it on the back of Lin Moming's hand like shaking hands with a child, "Can you speak Chinese?"

"I just said ......"

"Oh oh, I'm sorry ......"

After Shen Yiyun got up, he let a few seniors go first, and then turned around and said to the operation and maintenance engineer who was sorting out the operating table in the laboratory, "Brother Liu, I know this group of people, why don't I keep an eye on it?"

"No, I had to be there the first time. The glasses brother at the table waved his hand and said, "You've changed your clothes, right? ”

And just like that, at 7:15, the marginal group of science finally entered the cryo-EM laboratory.

Like many labs, this is an ensuite, with desks and workstations on the outside.

Through the glass, you can see the cryo-EM in the back room, this thing is like a gray metal microscope magnified to a height of two meters, there is no sense of technology, but there is a sense of simplicity, it seems to be a few cylindrical metals together, not much better than the model put together by Tu Yikou.

Of course, Zhou Yi also made it clear that this one in the Academy of Chemistry is a low-profile version from a few years ago, and it cannot be compared with the one in the Academy at all.

According to the regulations, anyone who uses cryo-EM needs to operate under the guidance and supervision of a specialized engineer, and in many cases, the person who is engaged in the project can only entrust the operation to an engineer.

As today's responsible engineer, Liu Tao can naturally be more relaxed when he is familiar with Shen Yiyun's group, but in the face of Li Zheng's group, he actually didn't plan to let them touch anything at all, and he was ready to operate as a complete agent.

Taking advantage of the registration of Li Zheng's group, Shen Yiyun lobbied frantically to Liu Tao, and he reluctantly agreed that Li Zheng's group could carry out "some moderately slow operations".

This process unconsciously consumed another ten minutes.

Obviously, there were only 4 hours of use, and nearly half an hour was wasted.

As steady as Mo Nian, it is inevitable to be a little anxious.

Liu Tao was still not in a hurry, let a few people sit down, and then opened a document and read it out.

"I'll talk about the main points of the specification manual first......"

Mo Nian couldn't bear it anymore and raised his hand and said, "Teacher Liu, we have memorized this document." ”

"Have you memorized everything?" Liu Tao turned his head and raised his glasses, "I mean all of you, have you memorized all the content?"

Hearing this, everyone looked at the leader.

The leader, rarely cramped, said to Liu Tao.

"So, friend, you just tell me and let them go in first. ”

Liu Tao only shook his head and smiled, turned to a page casually and said: "What are the four steps used in cryo-EM?

Mo Nian said like an autonomic reflex: "Sample preparation, projection electron microscopy imaging, image processing and structural elucidation. ”

"Hmm......" Liu Tao nodded in surprise, then glanced at a few people and said, "What should I pay attention to in sample preparation......?" The little girl replied. ”

Ageism is everywhere, although Lin Moming wanted to scold, she still chose the overall situation, and only gritted her teeth and said fiercely.

"The samples must be very pure, mostly crystal-based, and are commonly prepared by flash freezing and spray freezing, and from the layout of this laboratory, it should only be liquid nitrogen freezing. ”

"Wow, I know a lot. Liu Tao had the urge to give a thumbs up and encouragement.

"No one knows better than I do. Lin Moming also had an urge to stick out her tongue and squirt water to make a grimace.

Liu Tao looked at the rest of the people again, and then asked, "Briefly talk about the safety points of the cryo-EM laboratory...... Well...... Trouble another female classmate to answer. ”

Chang Qiqing immediately said unhurriedly: "The temperature is maintained at 20-25 °C, the humidity is 40%-60%, any failure and damage are reported to the administrator in time, it is strictly forbidden to drink water, it is strictly forbidden to use conductive objects to contact the power supply, do a good job of electrostatic protection, and maintain the equipment ......"

"Okay, it's enough......" Liu Tao wiped his sweat nervously, and finally looked at Li Zheng, and was just about to ask a question, when he met the pair of eyes that continued to stare at him.

Although Li Zheng didn't have any words, his eyes were full of hunger and thirst.

Come!!Come!!Come on!!

I'm in good spirits!!

Hurry up!!

Time is running out!!

Seeing such a pair of excited eyes, Liu Tao swallowed the question back.

Don't test him...... He knows better than I do.

Liu Tao closed the document and nodded effortlessly.

"Well, very energetic, very energetic...... Let me ask you first, do you have a plan document?"

Chang Keqing instantly handed over the experimental materials in his hand: "Please." ”

Liu Tao looked as fast as he could, and in the face of such a spirited Li Zheng, he didn't dare to delay any longer.

But even so, the process still took another 10 minutes.

"Planned ...... It's really clear...... "Liu Tao saw the end, his palms were sweating, and his voice was a lot weaker, "The question is...... This kind of experiment...... I've never done it before...... No, no, it's not me, it's that no one has ever done this with an electron microscope......"

Shen Yiyun also kept staring at the material behind him, and he was inevitably confused at this time: "This method ...... It's really different from what we do about organic photovoltaic materials......"

After that, she looked up and asked, "Has this process been introduced by a foreign laboratory?"

By this time, Li Zheng was so energetic that he couldn't be more energetic, and his spirit was irritable.

"This is an experiment to create a new method, and the specific situation has been clearly stated in our project report. Li Zheng nodded at Liu Tao and said, "This experimental plan has already been sent to your mailbox." ”

"Ah...... Yes......" Liu Tao gasped, rubbed the back of his head and said, "I thought it was more conventional...... Material Analysis ...... It's just to make a small paper, any journal that publishes it...... In fact, most of our experiments are that kind of experiment, after all, cryo-EM is a new technology, and it is easy to ...... It was easy to come up with a paper, but I didn't expect it...... You are the ...... of this groundbreaking subject."

Liu Tao paused when he said this, and then thought again: "I'm not easy to control this...... In that case, I would like to ask for instructions...... No, no...... I have to send the experimental materials to several leaders for instructions......"

Hear this.

A collective glare appeared.

Even including Shi Yang.

"Brother Liu, aren't we?" Shi Yang stepped forward and said, "There are no dangerous points in this experiment, it's just that some optimizations have been made for small molecules, and it's even simpler than many experiments, and we've done all the work with instructions." ”

"But this set of procedures is not in ......the standard experimental manual," Liu Tao shook his head again and again, "We only do experiments with rules to follow...... Unless it's a professor, you can do something groundbreaking......"

"This is a project that Boss Zhou nodded to. Shi Yang nodded and reported, "This is not enough?"

"But ......," Liu Tao said as he flipped through the materials, "There is no name of Dean Zhou on it, even if it is the instructor." ”

"Oh, don't you want this!" Shi Yang scratched his head in annoyance, "It's hard to come in, why do you still make such a fuss." ”

At this time, Li Zheng's hand had already reached into his pocket.

He really didn't want to bother Zhou Yi because of such a small matter, but the experiment time was only 4 hours in total, and 40 minutes had passed.

After hesitating, Tu Yikou suddenly pressed his arm, and after giving a "brother steady" look, he got up and walked towards Liu Tao leisurely.

"Friend, I know what you think, but let me be blunt and say a few things that have to be offended. Tu Yikou pursed his lips and patted Liu Tao's little brother, "Friend, look, our reports, document processes and other things have long been in place, but you only see now, is there an element of malfeasance in it? According to your so-called processes, you should also be prepared accordingly before we enter, right?"

Being slapped like this by Tu Yikou, Liu Tao tried very hard and said, "This ...... This experiment was added suddenly, and it was too late to ......"

"It's okay, I'm not done yet. Tu Yikou then grabbed the experiment report and patted it on the table, "Friend, look at it again, this experiment is a project initiated by Dean Zhou himself, and many leaders have approved it, which may mean that they attach great importance to this experiment, or it may mean that there are people among us that you can't afford to provoke, but these are not important, the important thing is that you are not not giving us face now, but not giving face to the leaders, not to our background, and not to give face to the future of Chinese scientific research." ”

"............" Liu Tao became more and more nervous, and unconsciously wiped his sweat again, "...... That...... Hold on...... I'll take a look at those instructions again......"

"Don't worry, I still haven't finished speaking. Tu Yikou raised his hand and looked around, "This is an important place for electron microscopy, the opportunity is precious, we are also extraordinary husbands and women, we should race against time, this experiment is not violated, it is purely beyond your cognition, in this situation, you have delayed the country's resources and wasted the time of many international competition champions because of an unwarranted responsibility, what should you say?"

“......”

"Dereliction of duty is unkindness, disobedience to leadership is disloyalty, and delaying our time is unjust. Tu Yikou finally slapped Liu Tao again, "Go back, friend, don't do this kind of thing." ”

"I ...... I ......" Liu Tao was about to cry, and only turned to look at Shen Yiyun, "That...... You help me keep an eye on the ......."

"Staring ...... Staring at ......" Even Shen Yiyun was infected, "I don't dare not stare at ......"

After some ideological work by the leader, finally at 19:47, Li Zheng and his entourage entered the inner room and stood in front of the cryo-electron microscope.

Out of the pursuit of efficiency, the first experiment was led by Shi Yang and Mo Nian, Li Zheng commanded the overall situation, Chang Keqing recorded the whole process, Lin Moming watched the excitement, and the leader took the opportunity to study the structure and parts of the electron microscope.

According to Liu Tao's request, they carried out the experiment as slowly and moderately as possible, and at the same time explained their behavior to ensure that everything was under Liu Tao's control.

This leads to a comical scene.

They seem to have become teachers, lecturing to Liu Tao......

Mo Nian first took out a bag of white powdered crystals and slowly displayed them in front of Liu Tao: "This is the model compound we chose - progesterone. ”

"Oh......" Liu Tao answered with his mouth open.

"So now...... I'm going to pour it on paper......" Mo Nian said, slowly spreading the progesterone powder on the paper, and then raised his hand at Shi Yang.

"And what about me?" Shi Yang raised his hands and gestured, "I'm going to take a small amount of progesterone powder and put it between two coverslips of glass to crush it, see clearly......"

"Oh oh......" Liu Tao nodded vigorously.

When Shi Yang was doing it, Mo Nian was still explaining beside him: "Next, Shi Yang will deposit the crushed fine powder on the porous carbon copper mesh...... In the meantime, I'm going over there to get liquid nitrogen...... See, I'm wearing gloves and I'm not going to get frostbite. ”

Shi Yang continued: "Then, when Mo Nian takes the liquid nitrogen, I will put this copper mesh in for quick freezing, and then put it in the electron microscope to start collecting information......"

"Okay...... Okay" Liu Tao finally couldn't bear it anymore, "You guys do it...... Stop it...... It's like I'm mentally retarded......"

"Didn't you ask for it, Brother Liu. Shi Yang laughed.

"Don't be poor, liquid nitrogen is coming. Liu Tao waved his hand, "Who knew that a few of you freshmen were all familiar with ......"

Next, without Liu Tao's various requirements, the steps were much smoother.

When the sample was placed in the electron microscope, everyone immediately moved to the workstation screen next to it, and Shi Yang operated the software to carry out the rotation projection required by Li Zheng.

Figuratively speaking, this is like a molecular-level CT, through a large number of scans from different angles, the structural model of the entire molecule is constructed, so how to control the rotation and how long to rotate is a very efficient issue.

Liu Tao and Shen Yiyun also joined in at this time, making suggestions on the side.

And Li Zheng and Chang Keqing were already in front of the experimental table next to them, making the next set of samples.

According to Li Zheng's plan, within a limited time, the six members of the group should operate as many experiments as possible, which is detrimental to efficiency, but it is worth sacrificing for a stronger talent reserve.

No way, as the Demon Emperor, this is the minimum pattern.

He knew what every lab was busy with day and night, and he also knew that Huanghe 2 involved hundreds of units and thousands of engineers and scientists.

He knew that the expensive equipment in front of him was likely to be a toy from a private middle school in Europe and the United States, and he also knew what Zhang Shandong and Liu Tao were thinking, and what Zhou Xiao was insisting on.

He knew that there were demons like Yang Zhenhua and Xie Qifen, but this world also needed academic leaders like Xu Youyou and even Chu Youhua.

The edge of science is his home base, and this laboratory is his first battle.

At this time, in Li Zheng's vision, the form of the scientific margin has undergone a mysterious change.

No longer a team in the Canyon Battlefield, and no longer a group in the next dungeon.

But......

Chief of Staff: Chang Keqing.

Diplomat: Lin Moming.

Political Commissar: Tu Yikou.

General: Mo Nian.

Commander-in-Chief: Li Zheng.

As Zhou Yi said, it is necessary to become famous as soon as possible.

I'm up to it.
