"Are you okay over there in Tongxian?"

Zhang Long's face was not very good-looking, and he wrote two words in Qin Jun's palm after half a sound, and only after half a sound did Qin Jun pat Zhang Long on the shoulder, "It's okay this way, it's easier to move on the bright side!"

"I know you still have something, and I won't keep you much, take care of yourself!"

Zhang Long nodded, the materials were delivered, and the rest was to go back to Tong County and wait for the orders from above.

Zhang Long didn't know how much shock he had caused after he sent out a secret order.

"What Comrade Zhang Long said in his letter, how do you think it is credible?"

"The origin of those two people has been investigated over there, they are Chinese who came back from country M, and this time they returned to China to build the motherland, and they can't find out the specifics!"

"The person who can make a shot is thousands of catties of rice and thousands of cotton clothes should be credible, and the other party directly stated that he already knows Zhang Long's true identity, so he can give it a try, in case the other party can really produce anti-inflammatory drugs and special drugs, this is good news for us and the soldiers on the battlefield!"

"I agree!"

"I think we should send someone to protect them, look at this meaning, that Mrs. Mu should be a pharmaceutical expert, such a person should be well protected!"

"Doesn't Zhang Long have an intersection with them, let Comrade Zhang Long protect their safety!"

Everyone also nodded, "Then how should this be chosen?"

"It must be a person who is loyal to the organization, and there must be no more traitors, if it weren't for Mr. Mu and Mrs. Mu, Comrade Zhang Long would have returned to the West!"

"Comrade Zhang Long, this is a blessing in disguise, if he hadn't broken into that house by mistake, who would have known that there are still people like Mr. and Mrs. Mu in this world!"

"Aren't there several of our comrades who are doctors and nurses in big hospitals such as Shanghai and Tianjin, let them recommend a few credible people, and we will do another identity screening, this matter is very important, and there can be no problems!"

"Yes!"

On the other side, Mu Hancheng and Liu Qianqian chatted happily with Miles, the purchase of the production line has been negotiated, and because of their generosity, Miles also gave them some small things, I have to say that Miles is a businessman who is very good at things.

Walking out of the cocktail party, 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 had faced such a place.

"Let's go back first!"

Liu Qianqian nodded, "The production line will arrive in Tongxian in half a month, we now need to prepare some raw materials for the production of drugs, extract penicillin, and also need to culture strains, although it is not very complicated, but each part needs to be accurate, and there can be no mistakes in the intermediate process!"

"When the time comes, I will make a list and let Zhang Long prepare!"

Mu Hancheng nodded, "Thank you for your hard work!"

Liu Qianqian pursed her lips, "No, I just move my mouth, and leave the rest to them!"

In addition, penicillin extraction and culture is very simple and can be used quickly, as for the machine operation, it is even simpler.

After Zhang Long came back, the first task he met was a shopping list, as soon as he heard that it was used to produce antibiotic drugs, Zhang Long didn't feel tired at all, and even felt in his heart that Mu Hancheng and Liu Qianqian were too simple, if he was a bad person, they would be dangerous, and he also told them to be careful, don't trust others, this is the first time Mu Hancheng heard others say that he is simple, and suddenly there is a feeling of crying and laughing.

Zhang Long thought that Mr. Mu and Mrs. Mu had spent too much, thinking that they had paid for these raw materials, Liu Qianqian directly threw over a bag of ocean, "We are not short of money, our original intention of returning to China is to serve the motherland, hurry up!"

Zhang Long's eyes were slightly red, nodded, and made up his mind to protect the safety of the two of them, for the past few days, if there are no people near the house, Mu Hancheng and Liu Qianqian have turned a blind eye, and the organization has taken a fancy to 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 has not yet arrived, the staff is ready to work, the small workshop is a total of 200 square meters, fermentation workshop, cultivation workshop, extraction workshop, synthesis workshop, and finally drug molding, in short, the need for personnel is not too much.

Although the equipment has not yet arrived, everyone is not idle, Liu Qianqian began to explain to them some knowledge about antibiotics, from fermentation and cultivation to the final synthesis, simple and easy to understand, after a few classes, Liu Qianqian has a higher status in the hearts of these people, this is a genuine pharmaceutical expert, must be well protected.

As soon as the production line arrived, Liu Qianqian took them to install and debug it personally, and a month later, the first step of antibiotics was finally started, fermentation.

"In the first step of strain fermentation, Penicillium chrysogenes are inoculated on a solid medium, and cultured at 25 °C for 7~10 days to obtain Penicillium spore culture. ”

"In the second part of extraction and refining, the penicillin fermentation broth is cooled and filtered. ”

"Now everyone looks at my operation, if you have any questions, you can ask questions!"

"Yes!"

Liu Qianqian took the students to start the first step of strain fermentation in the laboratory. The spores were inoculated into the sterilized medium in the seed tank with sterile water, stirred, and incubated at 27 °C for 24~28h, and then the seed culture medium was inoculated into the sterilized medium containing BYS precursors in the fermenter, sterile air was introduced, stirred, and incubated at 27 °C for 7 days. During the fermentation process, BYS precursors and appropriate amount of medium should be added.

One morning, Liu Qianqian and these people were nested in the laboratory, and after they had mastered it thoroughly, the next step was to extract and refine.

Half a month later, when the local penicillin was produced from the workshop, everyone burst into tears, they themselves were able to produce antibiotics, they were also able to produce anti-inflammatory drugs, and the soldiers on the battlefield no longer had to worry about wound inflammation and infection, which was really good!

With the first branch, there is a second branch, and then the entire small factory runs rapidly, and after all of them have mastered it thoroughly, Liu Qianqian will not go to the laboratory at all.

"Mrs. Mu, thank you, thank you very much!"

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 had to do, and I also hope that these medicines can help the soldiers on the battlefield and treat more injured soldiers!"

"Thank you!"

Liu Qianqian took out a few prescriptions from her arms, "This is some healing ointment, it has a miraculous effect on the healing of knife wounds and gunshot wounds, and it is not difficult to make, you take it, and when the amount of penicillin is enough, you can try to produce some ointment!"
