"Researcher Li, you haven't eaten yet? I brought you dumplings from home. They're hot!"
Dong Yazhu walked in carrying two aluminum lunch boxes, her hair and eyebrows were stained with frost.
"Dumplings?" Li Donglai was stunned.
"Yes, today is the winter solstice. According to the custom of Ji Chun, you have to eat dumplings, otherwise your ears will freeze off."
Dong Yazhu pinched her ears and showed fear.
Only then did Li Donglai remember that it was already the winter solstice before he knew it.
I don’t know if Ding Qiunan and Li Xiaomei have eaten dumplings at home.
Due to confidentiality reasons, members of the project team are not allowed to contact their families.
The dumplings are filled with pork and green onions. I don’t know what secret recipe Dong Yazhu’s mother used. The filling of the dumplings is very delicious.
That kind of fragrance is not caused by adding too much oil to make people's mouth feel fragrant.
Rather, it makes people feel the fragrance from the inside out, and once you take a bite, your soul will be rippling.
Li Donglai only ate two before he narrowed his eyes. He looked at Dong Yazhu and said with a smile: "Have you eaten yet?"
"After eating, my mother just took it out of the pot, so I ate it while it was hot."
"What about the comrades in the project team? Forget about the young people. Professor Zhang and Professor Wang all came from the old world and are more reasonable." Li Donglai asked.
"They have also eaten. This morning, the institute's breakfast is dumplings." Dong Yazhu seemed to know that Li Donglai was a careful person, and added: "I have asked Captain Liu to send someone to deliver the dumplings to the hospital to ensure that Zhang
Sister Qingcui can also eat it."
"Well, it seems I'm the only one left now."
Li Donglai was no longer polite at this time, shook his cheeks, and ate happily, and soon the dumplings in the two lunch boxes were eaten.
Dong Yazhu felt happy when she saw Li Donglai eating so deliciously.
These dumplings are exquisite. Two days ago, she asked a friend to buy fresh meat from the market.
It's winter now, and the Chinese New Year is just over a month away. Even if you have meat stamps, it's hard to buy meat.
....
After eating, Li Donglai took Dong Yazhu to the laboratory.
Zhang Qingcui was away, and Dong Yazhu seemed to have become an assistant. Following Li Donglai's instructions, he began to sort out the materials needed for the experiment.
At this time, the researchers also had breakfast and came to the laboratory one after another.
They had already heard about what happened last night from their comrades at the institute, and the way they looked at Li Donglai was completely different from the past.
Human beings are born with an obsession with weapons that can harm other humans or animals. This obsession stems from the survival instinct and is engraved in genes. Even these researchers who bury themselves in piles of books all day long are no exception.
When they were young, they also dreamed of one day holding guns and showing off their might on the battlefield.
Professor Zhang is an outgoing person. He walked quickly to Li Donglai, looked him up and down exaggeratedly, and was amazed.
"Hey, I didn't expect that there is a sharpshooter in our project team. Comrade Donglai, tell us, what does it feel like to shoot? Did your hand tremble when you pulled the trigger?"
Li Donglai took the materials handed over by Dong Yazhu and said with a smile: "Shouldn't you ask Lao Liu and the others about this kind of thing? When they were young, they had actually been on the battlefield. What I faced was just a man with a dagger.
I'm a coward, I can't do anything."
Professor Zhang glanced at the security personnel who were busy helping the institute with the security check, curled his lips and said: "They are born warriors. Even if they are shot, they probably won't even blink. Compared with us, we haven't even killed a chicken."
Can people who have lived through it be the same?"
Li Donglai thought for a moment that this was really the case. He raised his eyelids and thought for a moment, then said: "I don't feel anything special. I just stared at that guy's calf closely, and then he didn't aim. He adjusted the muzzle according to his own feeling and directly pressed the gun."
Pull the trigger and that's it."
"Not aiming? Who do you think you are? A sharpshooter?" Professor Zhang expressed disbelief, and the researchers next to him also shook their heads.
"According to the principle of light propagating along a straight line, when aiming, only three points and one line can accurately hit the target. If you don't aim, who are you kidding?"
"That's right, that's right, I think Team Leader Li is inflated now."
...
Captain Liu, who had finished the security check, came over, patted Li Donglai on the shoulder, and said: "I believe what Captain Li said. The reason is very simple. When I first joined the army, the veterans told us that on the battlefield, you bunch of raw melons
Danzi, you have to forget all the skills and fight purely on instinct, otherwise, you will be the first to die.
Also, three points and one line is simple to say, but if you want to achieve it, it will be affected by many factors.
For example, a 54 gun weighs 0.85 kilograms. If it is filled with bullets, it weighs 1 kilogram.
To pick it up with one hand and keep the gun in a stable state is impossible without hard training."
The researchers were relieved and said one after another: "Team Leader Li, now you are the spearhead of our research team."
Li Donglai did not refuse this title. After all, not long after he and Ding Qiunan got married, Ding Qiunan became pregnant.
It is not an exaggeration to say that he is a sharpshooter.
....
Thanks to two days of rest, everyone is more energetic than before.
After the fourth experiment started, Li Donglai clearly felt that the researchers' operations had become more precise, and the calculated data were almost the same as the theoretical data.
It only took half a day to complete the preliminary preparations.
Li Donglai came to the electron microscope laboratory, looked at Dong Yazhu who was standing next to the instrument and said:
"Comrade Dong Yazhu, now it's your turn, do you have confidence?"
"Report to the team leader, I am confident."
"Okay, I'll give the order first, and the fourth pharmaceutical experiment will officially begin."
Following Li Donglai's order, Dong Yazhu turned around and turned on the power cabinet switch of the electron microscope, and a bright beam of light shot out from the light fill hole on the upper part of the electron microscope.
Dong Yazhu stood next to the tall cylindrical lens tube. Her thin body looked extremely small, but even this small body burst out with unimaginable energy.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! She took a deep breath, pulled the handle, and there was a "hissing" friction sound in the lens tube, and several cylinders inside the lens tube began to
Move up and down slowly.
Li Donglai had also operated an electron microscope in his previous life and knew that Dong Yazhu was taking the most difficult and critical step in operating an electron microscope - adjusting the focus of the electron lens.
The adjustment of the focus of the electronic lens is related to whether organic molecules can be clearly seen.
In previous lives, this kind of adjustment was controlled by computers. Researchers only needed to input instructions into the system, and the computer would actively and precisely adjust the electronic lens based on the information fed back by the sensing device.
The accuracy of this kind of adjustment often needs to reach the nanometer level, which is almost difficult to complete by hand.
However, this did not seem to be a problem for Dong Yazhu. She frowned, held her breath, and turned the handle bit by bit.
Sometimes, the scale of rotation is relatively large, and sometimes, the scale of rotation is so small that only Li Donglai keeps staring at her to detect it.
Time passed bit by bit, and large drops of sweat oozed from Dong Yazhu's forehead.
But she didn't wipe it with her hands, because once she spilled her hands, the hard-earned feel would disappear.
Seeing that a drop of sweat was about to slide down her fair cheek into the corner of her eye, Li Donglai couldn't bear it anymore and took a towel from the side.
He walked over and carefully wiped away the sweat drops for Dong Yazhu.
Feeling the gentle movement, Dong Yazhu's heart palpitated, but she knew very well that this was a critical moment and could not tolerate any distraction.
She bit her lip, gathered her thoughts, and devoted all her body and mind to operating the electron microscope.
1 nanometer, 2 nanometer, 3 nanometer...
The scale that humans cannot observe with the naked eye was approached bit by bit by Dong Yazhu using his instinct and talent.
finally.
"found it!"
The clear shadow appeared in the lens, and Dong Yazhu couldn't help but cheer.
She quickly pressed the lock button, turned her head, and looked at Li Donglai excitedly: "Researcher Li, the accuracy has been locked and the experiment can be carried out."
Although the researchers outside the door could not hear the sound, they could judge the progress from Dong Yazhu's expression.
They all breathed a sigh of relief. In the whole experiment, the most difficult thing was adjusting the electron microscope.
Li Donglai opened the door and said with a smile: "The comrades from the Institute of Optoelectronics have completed their tasks, now it's our turn!"
Professor Zhang Laodang Yizhuang patted his chest and said, "Team Leader Li, don't worry, we will definitely find that cute little thing this time."
He and another researcher turned around and took out the organic macromolecules that had been generated from the instrument, and began to observe them using an electron microscope with the assistance of Dong Yazhu.
The entire observation process took about half a day, so Li Donglai didn't have to keep staring here, so he returned to the laboratory next door and started preparing the reactor.
The reactor has been cleaned out by researchers, who are adjusting the proportions of compounds based on the data calculated by Li Donglai.
Li Donglai checked the correctness of the data one by one. Just after checking two, there was a rapid knock on the door of the laboratory.
Li Donglai frowned. He had already given the order before the experiment.
Since the experiment must be conducted in a quiet environment, anything that happens cannot be disturbed.
However, the person outside the door seemed to be in a hurry, and the knocks on the door kept coming.
Since the door of this kind of laboratory is made of metal, the sound of knocking is very harsh, which has been noticed by many researchers.
They all stopped and looked towards the door, their eyes full of doubts.
Li Donglai waved his hands at them: "Everyone, take a rest. I'll go see what's going on!"
Go to the door, press the red button, and hear a "pop" sound, and the door is opened from the outside.
What came face to face was Captain Liu's anxious face.
Li Donglai frowned: "Captain Liu, what happened?"
Captain Liu did not enter the laboratory, but stood at the door and said: "Our team members staying at Jichun No. 1 Hospital intercepted a person from Beijing University. According to him, he is Zhang Qingcui's friend. He heard that Zhang Qingcui
She was sick, so I traveled a long distance to visit her in the hospital. This matter involves the project team, so I'm not sure I'll pay attention."
Li Donglai immediately understood Captain Liu's concerns. The experiment was currently in full swing, and Zhang Qingcui was also someone who knew the inside story of the experiment. If the visitor had ulterior motives, there was a possibility of leaking the secret.
While secretly sighing at the high level of confidentiality among Captain Liu and others, Li Donglai also had some doubts in his heart.
"Who knows about Zhang Qingcui's illness?"
Captain Liu said: "According to relevant regulations, after Zhang Qingcui fell ill and was sent to the hospital, I reported to Secretary Zhang of the school committee of Capital University. Because Zhang Qingcui is a faculty member of Capital University, once there is a physical problem, we will not
The method was explained to Beijing University. However, during the reporting process, I also told Secretary Zhang about the relevant confidentiality requirements. Secretary Zhang’s confidentiality level is very high."
At this point, he suddenly realized: "By the way, the person who came here also said that he is Secretary Zhang's secretary, named Liu Feng. I have asked comrades in the capital to retrieve Liu Feng's files, but there is no reply yet."
"Liu Feng? I seem to have heard of this name." Li Donglai thought for a moment, and he was not sure whether Liu Feng was Zhang Qingcui's friend.
Moreover, there was no way to mention this matter to Zhang Qingcui. If Zhang Qingcui insisted on meeting Liu Feng, there would inevitably be the possibility of leaking the secret during their conversation.
The first principle of confidentiality work is to control the number of people who know the information to the minimum range.
Li Donglai thought for a moment and said: "Ask the comrades at the hospital to tell Liu Feng that Zhang Qingcui cannot meet him due to physical reasons. At the same time, call Secretary Zhang and ask Liu Feng if it is his intention to come to visit Zhang Qingcui."
"I understand, I'll do it right now!" Captain Liu glanced at Li Donglai in admiration, then turned around and left quickly.
What those who do security work like them are most afraid of is that the researchers have no idea of confidentiality, and there are flaws everywhere when they do things.
Li Donglai's decision may seem ruthless, but it can prevent the leakage of project information to the greatest extent.
Although Liu Feng seems to be a clean guy, the enemy agent doesn't want to write his name on his face, so it's better to be cautious.
Captain Liu left in a hurry, and Li Donglai returned to the laboratory.
"Okay, it's okay, just some minor problems, big guys, let's continue!"
....
The operation was interrupted, and the impact was more serious than Li Donglai imagined.
During the experimental operation at this time, Lao Zhang and Lao Liu made two fatal mistakes in succession, causing the samples that were finally produced to be contaminated.
After another experiment failed, Li Donglai looked at the researchers listlessly cleaning the instruments and smiled bitterly.
It seems that next time we start the experiment, we should choose an auspicious day.
....
After the experiment failed, Li Donglai thought he would feel very heavy, but in the end he found that he could accept it calmly.
Because he knew that in this era, to use these crude instruments to create medicines for future generations would require not only hard work, but also a little bit of luck.
