Zhang Long's face was not very good. He wrote two words on Qin Jun's palm for a while. After a while, Qin Jun patted Zhang Long's shoulder and said, "This is good, it will be easier to move in the open!"
"I know you still have something to do, so I won't keep you any longer. Just take care of yourself!"
Zhang Long nodded and the supplies were delivered. All that was left was to go back to Tong County and wait for orders from above.
Zhang Long didn't know how much shock he caused after his secret order was sent out.
"How credible do you think what Comrade Zhang Long said in his letter is?"
"The origins of those two people have been clearly investigated over there. They are Chinese who came back from country M. They returned to the country this time to build the motherland. The specific details cannot be found!"
"A person who can sell thousands of kilograms of rice and thousands of cotton-padded clothes in one move should be trustworthy, and the other party directly stated that he already knows Zhang Long's true identity, so he can give it a try, just in case the other party can really produce anti-inflammatory drugs and special effects
Medicine, this is good news for us and the soldiers on the battlefield!"
"I agree!"
"I think someone should be sent to protect them. Judging from this, Mrs. Mu should be a pharmaceutical expert. Such a person should be well protected!"
"Don't Zhang Long have a relationship with them? Comrade Zhang Long can protect their safety!"
Everyone nodded, "Then how should we choose people?"
"They must be loyal to the organization, and there must be no more traitors. If it weren't for Mr. Mu and Mrs. Mu, Comrade Zhang Long might have died in the West!"
"Comrade Zhang Long is a blessing in disguise. If he had not broken into that house by mistake, who would have known that there were people like Mr. Mu and Mrs. Mu in this world!"
"We have several comrades who work as doctors and nurses in major hospitals such as Shanghai and Tianjin. We asked them to recommend a few trustworthy people. We will do another identity screening. This matter is of great importance and there must be no problems.
!”
"Can!"
On the other side, Mu Hancheng and Liu Qianqian chatted happily with Miles. The purchase of the production line had been negotiated, and because of their generosity, Miles also gave them some small gifts. I have to say,
Miles is a very capable businessman.
After walking out of the reception, Mu Hancheng and Liu Qianqian breathed a sigh of relief. To be honest, they really didn't like the atmosphere inside. This was the first time they faced such a place.
"Go back first!"
Liu Qianqian nodded, "The production line will arrive in Tong County in half a month. We now need to prepare some raw materials for drug production, extract penicillin, and culture strains. Although it is not very complicated, each part needs to be precise.
There can’t be any mistakes in the middle process!”
"I will make a list then and let Zhang Long prepare it!"
Mu Hancheng nodded, "Thank you for your hard work!"
Liu Qianqian pursed her lips, "No, I just move my mouth and leave the other things to them!"
Moreover, the extraction and culture of penicillin is very simple and you can get started quickly. As for the operation of the machine, it is even simpler.
After Zhang Long came back, the first task he faced was a shopping list. When he heard that it was used to produce antibiotics, Zhang Long didn't feel tired at all. He even felt that Mu Hancheng and Liu Qianqian were too naive. If
Since he was a bad person, they were in danger, and he kept telling them to be careful and not to trust others. This was the first time that Mu Hancheng heard someone say that he was innocent, and he suddenly felt like he was crying or laughing.
Zhang Long thought that Mr. Mu and Mrs. Mu had spent too much, and that they had paid for these raw materials through their organization. Liu Qianqian threw a big bag over and said, "We are not short of money. Our original intention of returning to China is to serve the motherland. Let's leave quickly."
!”
Zhang Long's eyes were slightly red, and he nodded, determined to protect the safety of the two of them. Mu Hancheng and Liu Qianqian turned a blind eye to the people who were around the house these days.
Now that the organization is interested in them, they will naturally not be unhappy, but they are afraid that they will be disappointed, because they will leave here soon!
The production line hasn't arrived yet, but the employees are ready to work together. The small factory has a total area of only about 200 square meters, including a fermentation workshop, a culture workshop, an extraction workshop, a synthesis workshop, and finally the drug molding. In short, not too many people are needed.
Although the equipment had not arrived yet, everyone was not idle. Liu Qianqian began to explain some knowledge about antibiotics to them, from fermentation and culture to final synthesis. It was simple and easy to understand. After a few classes, Liu Qianqian was among these people
The status in my heart is even higher. This is a genuine pharmaceutical expert, so I must protect him well.
When the production line arrived, Liu Qianqian took them to install and debug it in person. A month later, the first step of antibiotics was finally started, fermentation.
"In the first step of strain fermentation, Penicillium chrysogenum is inoculated onto a solid medium and cultured at 25°C for 7 to 10 days to obtain a Penicillium spore culture."
"The second step is extraction and refinement, cooling and filtering the penicillin fermentation liquid."
"Now everyone is watching my operation. If you have any questions during the process, you can ask!"
"yes!"
Liu Qianqian led the students to start the first step of bacterial fermentation in the laboratory. Use sterile water to make a suspension of spores and inoculate it into the sterilized culture medium in the seed tank, add sterile air, and stir
, culture at 27°C for 24 to 28 hours, then inoculate the seed culture liquid into the sterilized culture medium containing BYS precursor in the fermenter, ventilate sterile air, stir, and culture at 27°C for 7 days. During fermentation
During the process, BYS precursor and appropriate amount of culture medium need to be supplemented.
All morning, Liu Qianqian and these people stayed in the laboratory. After they had completely mastered it, the next step was to extract and refine it.
Half a month later, when the local penicillin was produced from the workshop, everyone burst into tears. They could also produce antibiotics themselves, and they could also produce anti-inflammatory drugs. Soldiers on the battlefield no longer had to worry about wound inflammation and infection.
This is really great!
With the first one, there will be a second one, and then the entire small factory will be running quickly. After all of them have completely mastered it, Liu Qianqian will not go to the laboratory at all.
"Mrs. Mu, thank you, I really appreciate you!"
Liu Qianqian smiled slightly, "Mr. Zhang, you don't need to be like this. My husband and I are also Chinese. We just did what we should do. We also hope that these drugs can help soldiers on the battlefield and treat more injured soldiers."
!”
"Thanks!"
Liu Qianqian took out a few prescriptions from her arms and said, "These are some healing ointments. They are very effective in healing knife wounds and gunshot wounds. They are not difficult to make. Just take them and wait until the amount of penicillin is enough. Then you can try it."
