I fought guerrilla warfare in the Yimeng Mountains during the Anti-Japanese War

"Leng, I see a strong hatred for the Japanese in your eyes. Let me assume that if one day you defeat the Japanese, what will you do to them?"

Chen Feng complained in his heart, just wait! In another two years, your eyes will be filled with hatred too.

"Winning is a matter of time. From now on, I have eight words to say: tooth for tooth, blood for blood."

"Okay, stop talking nonsense and tell me the news you are going to send me. I can't stand it anymore."

Chen Feng glanced at Li Yunyan beside him. Li Yunyan rode away first, and the rest of the people also avoided it. Qiao Piro reminded the two bodyguards, and the two bodyguards also fell behind by dozens of meters.

Have you heard of "Penicillin"?

"No, tell me is it a weapon or something? This name is weird."

"This is a medicine that will go down in history. I know how to make it using traditional methods. I can give it to you to study, but you have to give me a pharmaceutical production line and help me make some special tools and equipment. Also, you have to give me tens of millions of small glass bottles for medicine. You have to know that we are very poor here."

"Drugs, Leng, you made me happy for nothing, I thought it was something like your direct-fire weapons."

"Don't underestimate it. I can tell you responsibly that it will be more valuable than gold in the future."

"What kind? Treatment of tuberculosis? Or treatment of sexually transmitted diseases?"

Seeing Chen Feng looking at him strangely, Qiao Piro suddenly became angry.

"Leng, don't look at me like that. I don't have any of them. You have to know that the disease with the highest mortality rate now is tuberculosis, the most troublesome is sexually transmitted diseases, and of course there is polio. What direction are you researching?"

"Neither, it's used for anti-inflammatory. You have to know that once a conflict begins, the war will escalate and there will be a large number of casualties among soldiers. If you invent a medicine that can instantly reduce inflammation for the wounded, it can save millions or tens of millions of wounded soldiers from dying from inflamed wounds. Just imagine how crazy that would be!"

Chen Feng has been thinking about this matter for a long time. It will take another two years for the United States to mass-produce penicillin. He wants to make a fortune in these two years to make money for his future plans. The best thing is to find a partner. However, he can only find an American for the time being. Jonina's visit is an opportunity. Although Joe Pietro is engaged in arms, the brother and sister can use warships at any time. Obviously, they are not ordinary rich second generations. Behind them are either military bosses or consortiums. It is necessary to maintain good relations to clear the thorns for the future.

Joe Piero was obviously a little shocked. As an arms dealer, he certainly understood the casualties on the battlefield. In addition to injuries to vital parts, many people died slowly after being seriously injured. Even death from minor injuries was commonplace. The emergence of such a drug was not comparable to the violence of arms sales. It was just a money-making scam.

"Leng, to be honest with you, I don't really agree with you and Nina. She is my precious princess, you know? When she was in college, a arrogant businessman's son pursued her, but later his father was bankrupted by my father. You don't have to be nervous. I have changed my mind now. I will convince the old man in my family not to interfere in Nina's love."

Chen Feng grinned. Foreigners are always like this. They start to act frivolously before finishing the serious business.

"Pierre, let's talk business first. Is there any problem with the equipment, tools and glass bottles I mentioned?"

"As long as your method is reliable, there will be no problem. In addition, if you need any arms, I can give you a 40% discount. This is the same as the mysterious weapons, it is also an exclusive cooperation, right?"

"Yes, I have two small conditions. Would you like to hear them?"

Qiao Piero was almost excited. Not to mention two small conditions, twenty would not be a problem.

"you say".

"Don't sell to the Japanese. The world is so big, enough for you to sell. It doesn't matter if they buy it. Let them buy it from other countries at a high price. Anyway, it's your sales volume that's being taken, and it won't hinder you from making money."

"This can be considered. I can't make a clear guarantee, but I will definitely do my best to make this happen. What else?"

"Leave some food for me and don't interfere with our market."

"I can make the decision on this, brother. I can't wait to see the results."

"Go back to the mountain, I will take you to do it if you go back to the mountain."

There is a special cave on Mount Meng, which is more important than the captain's room. It is guarded by soldiers 24 hours a day. Only three people can enter, namely the captain, the dean and Engineer Liu. No one else is allowed to approach. It is full of various utensils and moldy oranges. The captain and Engineer Liu also brought in a lot of items stolen from Qingdao. No one knows what they are used for, but the captain has ordered that except for the three of them, anyone who appears in this location will be arrested and brought to him.

Something was strange today. The captain and Engineer Liu came with a foreigner, followed by two followers. The guarding soldiers could tell at a glance that the two followers had something special, but since the captain was there, the guards just glanced at the two followers.

In the cave, Liu Kuang began to extract penicillin.

Penicillium was previously extracted from moldy oranges and placed in a culture medium for screening and culture. The culture medium solution was made with taro soup, etc., and the Penicillium had been growing for some time.

In front of the captain and Qiao Piero, Liu Kuang began to filter the cultured penicillium liquid, added rapeseed oil and stirred it. After a while, the liquid in the container was divided into three layers. Liu Kuang's English was very solid. While refining, he introduced that penicillin was a water-soluble substance. Just release the water from the bottom opening to complete the initial purification of penicillin.

Liu Kuang introduced the situation. He injected the preliminary purified penicillin solution into the carbon powder or wood ash that had been boiled and sterilized, stirred it again, and then washed away the impurities on the carbon powder with distilled water. Then, he used acidic water made of vinegar and alkaline soda water to further remove impurities. After an hour, a penicillin solution with a higher purity was obtained.

After dropping penicillin solution into the staphylococcus culture dish, several people carefully observed the formation of the inhibition zone. After a while, a strange circle appeared.

"Captain, Mr. Joe, penicillin is effective."

Liu Kuang used sterilized rice paper for further purification. He painted the prepared penicillin on the paper and hung it vertically. The end was immersed in an acid-base-base solution. He used paper chromatography to further remove impurities. Liu Kuang began to brush the bottle. Qiao Piero saw clearly that an ordinary glass bottle was brushed three times and baked twice. He looked very careful. After more than half an hour, Liu Kuang covered the lid of the glass bottle and carefully baked the bottle mouth with an alcohol lamp.

"Captain, this can be used, but it also requires a skin test."

"Take it with you, let's go and find the dean"!
