Learning Demon Cultivation System

A viscous exclamation suddenly came from behind.

"Li Zheng?!"

Follow the reputation.

Here it comes, female slime!

Li Zheng also stared: "Although it's almost unrecognizable, but can grow to this size...Sister Shen?"

"Fuck!" Shen Yiyun cursed, and Ton Ton rushed over, "Who am I? Why did you go to Yingpei?"

"Hey, it's the same everywhere." Li Zheng turned around and introduced, "This is senior sister Shen Yiyun from the third year of the Institute of Chemistry. She taught me my experiments."

Several people shook hands and recognized each other.

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

"What the hell are you doing!"

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

"If I don't shake hands 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 or not."

"..."

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

But Li Zheng pulled him, coughed again, and pointed down.

Only then did Shen Yiyun find out.

It turned out that there was a little girl below who raised 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 see."

Li Zheng quickly explained: "This is our official team member Lin Moming."

"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, "Chinese? Can you speak it?"

"I just said..."

"Oh, oh, sorry..."

After Shen Yiyun got up, he asked the seniors to leave first, then turned to the operation and maintenance engineer in the laboratory who was tidying up the console, and said, "Brother Liu, I know this group of people well, why don't I keep an eye on them?"

"No, I have to be present for the first time." The glasses man at the table waved his hand and said, "Have you changed your clothes? Come in."

In this way, at 7:15, the scientific marginal team finally entered the cryo-EM laboratory.

Like many laboratories, this is a suite, with desks and workstations in the outer room.

Through the glass, you can see the cryo-electron microscope in the back room. This thing is like a gray metal microscope magnified to a height of two meters. It has no sense of technology, but has a sense of simplicity. Together, it is not much better than the model made by Tu Yikou.

Of course, Zhou Yi also made it clear that the one in the Huayuan is a low-end version a few years ago, and it can't be compared with the one in the Shengyuan.

According to regulations, anyone who uses a cryo-electron microscope needs to operate under the guidance and supervision of a specialized engineer. In many cases, those who engage in projects can only entrust engineers to operate.

As today's engineer in charge, Liu Tao can naturally relax a bit when facing Shen Yiyun's group of familiar hands, but facing Li Zheng's group, he actually doesn't intend to let them touch anything at all, and is fully prepared to act as an agent.

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

This process took another 10 minutes unconsciously.

Obviously only 4 hours of use time, nearly half an hour has passed in such a waste.

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

Liu Tao still took his time, let a few people sit down, and then opened a document and read it out.

"Let me talk about the main points of the specification manual..."

Mo Nian couldn't help but raised his hand and said, "Mr. Liu, we have already 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 turned to the leader.

The leader, in a rare embarrassment, said to Liu Tao.

"In this way, friend, you just tell me and let them operate first."

Liu Tao just shook his head and smiled, then turned to a page and said, "What are the four steps in using the cryo-electron microscope? That tall guy?"

Mo Nian said like an autonomic reflex: "Sample preparation, transmission electron microscope imaging, image processing and structural analysis."

"Hmm..." Liu Tao nodded in surprise, then glanced at several people and said, "Is there anything I need to pay attention to in sample preparation? This... this little girl, please answer."

Age discrimination is everywhere. Although Lin Moming wanted to scold, she still chose to look at the big picture and said vehemently through gritted teeth.

"Samples must be very pure, mostly crystals, and are commonly prepared by quick freezing and spray freezing methods. Judging from the layout of this laboratory, it should only be frozen with liquid nitrogen."

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

"No one understands better than me." Lin Moming also had the urge to stick out her tongue and spray water to make faces.

Liu Tao looked at the rest of the people again, and then asked, "Let me briefly talk about the safety points of the cryo-electron microscope laboratory... um... another female classmate, please answer."

Chang Keqing immediately said unhurriedly: "The temperature is maintained at 20-25°C, and the humidity is 40%-60%. Any failure or damage should be reported to the administrator in time. It is strictly forbidden to drink water, and it is strictly forbidden to use conductive objects to touch the power supply. Do a good job of electrostatic protection. , when maintaining equipment..."

"Okay, okay, that's enough..." Liu Tao wiped his sweat nervously, and finally looked at Li Zheng. Just as he was about to ask a question, he met those staring eyes.

Although Li Zheng didn't say anything, his eyes were full of hunger.

come on! !come! !Come on! !

I have the spirit! !

hurry up! !

Time is waiting! !

Seeing such excited eyes, Liu Tao swallowed the question hard.

Don't test him... He must know better than me.

Liu Tao then closed the document and nodded with difficulty.

"Okay, very energetic, very energetic... Then let me ask first, do you have any experimental plan documents?"

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

Liu Tao looked through the pages as quickly as possible. Facing such an energetic Li Zheng, he dared not delay any longer.

Even so, the process still took another 10 minutes.

"The plan...is indeed very clear..." Liu Tao saw the end, his palms were sweating, and his voice became weaker, "The problem is...this kind of experiment...I have never done it before. ...No, no, it's not me, no one has ever done this with a electron microscope..."

Shen Yiyun was also behind him staring at the materials, and at this moment he was inevitably confused: "This method...is indeed different from our analysis of organic photovoltaic materials..."

After finishing speaking, she raised her head and asked, "Has this process been introduced by foreign laboratories?"

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

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

"Ah... yes..." Liu Tao gasped, rubbing the back of his head and said, "I thought it was more routine... material analysis... just a small paper, published in any journal... actually Most of our experiments here are of that kind. After all, the cryo-electron microscope is a new technology, and it is easy to learn...it is easy to publish papers, but I didn't expect...you are such a groundbreaking subject..."

Liu Tao paused when he said this, and thought again: "I can't control this well... So, let me ask for instructions... No, no... I have to send the experimental materials to several leaders for instructions..."

Hear this.

There was a collective stare.

Even Shi Yang.

"Brother Liu, can't we?" Shi Yang stepped forward and said, "There is no danger in this experiment, it is just optimized for small molecules, it is even simpler than many experiments, and we have finished it even if we have to ask for instructions .”

"But this procedure is not in the standard experiment manual..." Liu Tao shook his head again and again, "We only do experiments with rules to follow... Unless the professor comes, we can really do some groundbreaking content..."

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

"But..." Liu Tao flipped through the materials and said, "President Zhou's name is not on it, even the instructor."

"Oh, do you want to do this!" Shi Yang scratched his head anxiously, "It's so hard to come in, why are you making such a fuss?"

At this time, Li Zheng's hand was already in his pocket.

He really didn't want to bother Zhou Yi because of such a trivial matter, but the experiment time was only 4 hours in total, and 40 minutes had passed, if it dragged on, it would be a question of whether it could be done today.

While hesitating, Tu Yikou suddenly pressed his arm, gave him a look of "brother is steady", got up and walked towards Liu Tao leisurely.

"My friend, I know what you think, but let me be blunt and say a few words that I have to offend." Tu Yikou pursed his lips and patted Liu Tao's younger brother, "Look, my friend, our reports, document procedures, etc. Things have been in place long ago, but you are only now looking, is there an element of dereliction of duty in it? According to your so-called procedures, before we enter the venue, you should have made corresponding preparations, right? "

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

"It's okay, I haven't finished yet." Tu Yikou then grabbed the experiment report and patted it on the table, "Friend, look again, this experiment is a project initiated by Dean Zhou himself, and many leaders have approved it. This 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 mess with, but these are not important. The important thing is that you are not giving us face now, but you are not giving face to the leaders. The background face of China, not the future face of China's scientific research."

"..." Liu Tao became more and more nervous, and unconsciously wiped his sweat again, "...then... wait a moment... I'll read those instructions again..."

"No hurry, I still haven't finished." Tu Yikou raised his hand and looked around, "This is an important place for electron microscopy, and the opportunity is precious. We are also ordinary people, and we should race against time. There is no illegal operation in this experiment, it is purely beyond your cognition Forget it, under such circumstances, you have wasted the resources of the country and wasted the time of many international competition champions because of an unwarranted responsibility, so what should we say?"

"..."

"Dereliction of duty is inhumane, disobedience to the leadership is disloyalty, and delaying my time is injustice." Tu Yikou finally patted Liu Tao again, "Turn around, friend, don't do this kind of thing."

"I...I..." Liu Tao was about to be told to cry, so he turned to Shen Yiyun, "Then... help me keep an eye on..."

"Stare...stare..." Even Shen Yiyun was infected, "Don't dare not to stare..."

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, Shi Yang and Mo Nian took the lead in the first experiment, Li Zheng took the overall situation to direct, Chang Keqing recorded the whole process, Lin Moming watched the fun, 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 actions to ensure that everything was under Liu Tao's control.

This leads to a comical scene.

They seem to have become teachers, giving lectures to Liu Tao...

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

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

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

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

"Oh..." Liu Tao nodded vigorously.

When Shi Yang was doing it, Mo Nian was still explaining next to him: "Next, Shi Yang will deposit the crushed fine powder on a porous carbon-copper grid...At the same time, I'm going to get liquid nitrogen over there...Look clearly, I Wear gloves so you won't get frostbite."

Shi Yang continued: "Then, when Mo Nian gets the liquid nitrogen, I'm going to put this copper grid in it 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...don't talk...it's like I'm mentally handicapped..."

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

"Don't be poor, liquid nitrogen is here." Liu Tao waved his hand, "Who knew that all of you freshmen are familiar with it..."

Next, without Liu Tao's various requests, the steps became much smoother.

After the sample was placed in the electron microscope, everyone immediately turned to the screen of the workstation next to it, and Shi Yang operated the software to perform the rotation projection required by Li Zheng.

To put it vividly, this is like a molecular-level CT. Through massive scans from different angles, a structural model of the entire molecule is constructed. Therefore, how to control the rotation and how long to rotate is a matter of efficiency.

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

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

According to Li Zheng's plan, within a limited time, the six members of the team must conduct as many experiments as possible. Although this will damage efficiency, it is worth sacrificing for a stronger talent pool.

There is no way, as a Demon Emperor, this is the minimum pattern.

He knew that every laboratory was busy day and night, and that the Yellow River No. [-] involved hundreds of units and thousands of engineers and scientists.

He knew that the expensive equipment in front of him was probably a toy from a private middle school in Europe and America, and he also knew what Zhang Shandong and Liu Tao were thinking, and why Zhou Xiao insisted on it.

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

The Margin of Science is his base camp, and this laboratory is his first battle.

At this time, in Li Zheng's vision, the shape of the edge of science has undergone another mysterious change.
