Siheyuan: Returning from studying abroad, with extraordinary understanding

However, Yi Zhonghai and Jia Dafu thought that one should not receive rewards without merit.

It was somewhat unrealistic for both of them to paint a rosy picture for the leader before even starting.

They don't want to do such a thing.

The idea of ​​seeking truth from facts has been ingrained into their bones.

Moreover, the purpose of their union is not to increase their salary, but to improve their own skills.

At the same time, it is also to help low-level workers improve their level. When their level is improved, their wages will naturally increase. With high wages, their lives will naturally be better.

Common prosperity does not mean that I will give you money just because I have money, but that I will teach you how to make money.

Promote rice and fight with rice and hate!

Without ideological transformation, this kind of situation can easily occur.

Yi Zhonghai and his friends were having dinner, but Lin Changqing, who was far away in the laboratory, was still instructing Zhao Yiming and others on how to identify and cultivate Penicillium.

Lin Changqing spent the entire morning finding large amounts of green mold from the rotten fruits and food residues.

However, these blue molds are not necessarily Penicillium, and even if they are Penicillium, not all of them can secrete penicillin.

Even among the strains that can produce penicillin, there are high-yield and low-yield strains.

For Zhao Yiming and others, the workload of identifying and distinguishing high-yield Penicillium is huge and cannot be completed in a short time.

You need to make a slide and observe it under a microscope to distinguish them.

None of them were researchers specializing in penicillin. If it weren't for Lin Changqing's explanation, they would not have been able to identify which Penicillium fungi could produce penicillin.

Zhou Yuan studied in the United States and visited laboratories, so he knew what the Penicillium that produces high levels of penicillin looked like.

However, all the ones he had seen were grown in laboratories, and searching for them in food scraps and rotten fruits was a huge challenge for him.

But, with Lin Changqing present, things were completely different.

Lin Changqing's mental power is very strong, and his eyesight is also very good. He can see the Penicillium that produces penicillin with his naked eyes.

His eyes were more useful than a microscope, and combined with his mental perception, he quickly found the Penicillium that produced a large amount of penicillin.

However, even if he found it, he couldn't point it out to everyone directly. He still had to explain to them the key points of identification and precautions.

Also, let them see what Penicillium looks like one by one under a microscope!

The whole morning was spent identifying bacterial strains, preparing culture media, and planting bacterial strains.

Except for Lin Changqing, everyone is a doctor and is relatively clear about the sterility requirements.

When collecting bacterial strains, try to do it as sterile as possible.

However, the laboratory conditions are somewhat poor, and it is not possible to carry out the work completely under sterile conditions.

Seeing this situation, Lin Changqing thought of several ways to improve the sterile conditions in the laboratory.

From the moment Lin Changqing entered the laboratory and began to explain the strains to them, he had become the leader of this experiment.

The other eight people, whether it was the two medical masters Zhao Yiming and Qian Yuanqing, or Liu Yulan and Zhou Yuan, a professor and a doctor of medicine, all obeyed Lin Changqing's arrangements like elementary school students.

Lin Changqing placed the required strains of bacteria on the culture medium, and after completing the cultivation work, he sped up the process.

All the strains of bacteria he selected were those that could secrete antibiotics. In order to reduce their working time, Lin Changqing picked them out directly.

In the future, these bacteria will be cultivated in a laboratory environment, and as a single strain without impurities, there will be no need to look for food scraps or rotten fruits.

"Okay, let's stop here." In the laboratory, Lin Changqing finally solved all the problems.

"Ah? That's all!"

"Teacher, please explain it again. There are still many things we don't understand!"

"Yes, teacher, don't end the get out of class!"

Everyone was still not satisfied!

"It's noon already, aren't you all hungry?" Lin Changqing glanced at the time. It was 12:30 noon.

"Not hungry!" everyone answered in unison.

"You're not hungry, but I am!"

Lin Changqing said unhappily, "Everyone, change your clothes quickly, wash them clean, wash them several times, and then go to eat."

"Yes, hurry up and eat. How can we let the teacher go hungry? Changqing, I'm sorry, it's our fault!"

"Yes, yes, let's go eat!"

Everyone came to their senses and felt a little guilty. The teacher taught them so much knowledge, but they let him starve. Damn it!

Lin Changqing smiled, said nothing, and walked towards the locker room.

After changing, Zhao Yiming took everyone to eat.

In the cafeteria.

Zhao Yiming and others were eating absentmindedly, looking at Lin Changqing from time to time.

"What's wrong with you? Why are you looking at me? I don't think there's any rice on my face?"

Lin Changqing naturally knew what they were thinking, so he wanted to tease them.

"Teacher Lin, you have taught us all the knowledge. Are you leaving soon?"

Hearing this, everyone put down their bowls and chopsticks and looked at Lin Changqing, wanting to get his answer.

Zhou Yuan also spoke:

"Teacher, please don't leave. We still have a lot of things we don't know and we need you to explain them to us!"

"Yes, yes! We all can't bear to part with you!"

Lin Changqing waved his hands quickly and said with a straight face:

"Who said I'm leaving soon? I have an experiment to teach you this afternoon!"

"Ah? Teacher doesn't have to leave?"

"That's great! Several researchers stood up with joy."

"I didn't even tell you that Changqing would leave, why were you so sad just now?"

Zhao Yiming pretended to be calm and said that he was extremely nervous just now, fearing that Lin Changqing would say, "I can only help you up to this point, and for the rest, you just need to follow my documents."

"Old Zhao, you didn't say it, but your expression betrayed you!"

Qian Yuanqing directly sabotaged Zhao Yiming, making him blush.

At the same time, he also began to expose Qian Yuanqing's shortcomings:

"Aren't you the same? And you're still talking about me!"

"Hahaha....."

Seeing the two bickering, everyone laughed.

The two of them were suddenly embarrassed, and Zhao Yiming quickly lowered his head and took a mouthful of rice to calm his nerves.

"Changqing, what experiment are you going to teach us this afternoon?"

Master's wife Liu Yulan asked curiously, glanced at Lin Changqing, and then quickly lowered her head.

Lin Changqing was her husband's student, so she was Lin Changqing's teacher's wife, but when she was teaching just now, Lin Changqing was her teacher.

She felt a little ashamed that she was not as good as the students and was treated as a teacher by the students.

It belongs to the category of turning the Tiangang upside down.

Everyone was also very curious.

Everyone was guessing, and soon someone came up with the idea.

However, they did not say it out loud, but looked at Lin Changqing with surprise.

I wanted to get the answer from him to confirm my guess.

"You guys have a good idea. I'll teach you how to make penicillin this afternoon!"

How could Lin Changqing not see what they were thinking?

If penicillin cannot be produced, his trip here will be in vain.
