After seeing off Desheng and the others, Zhou Heng stood there and sighed, and Boss Xue poked his arm.

"What's wrong? I'm sighing. Isn't this like you?"

Zhou Heng shook his head and looked towards the second floor.

"Mr. Zhang has been away for more than ten days, and the capital is not sure how it is going. Although Jinan Prefecture has allocated disaster relief silver, you see, Lord Liu doesn't seem to have a smile, only silver and no documents, what is this? Is this an advance payment? It depends on the face of Lord Zhang Fuling, how to deal with it in the future, and it depends on the investigation situation of Lord Zhang."

Boss Xue raised his chin and said, "Why do you think so much? Even if Jinan Mansion is unhappy, the money must be sent. As for Lord Zhang Fuling, he is a person worthy of admiration. I don't know how many interceptions he encountered along the way back to Beijing. It's not easy to have such persistence."

Zhou Heng nodded, "Yes, so we must be prepared and try our best to treat this guard."

Boss Xue smiled and approached her.

"Speak up, then what am I doing?"

Zhou Heng looked up and down at him. It seemed that there was no need for Boss Xue to make anything in front of him. There were still thousands of glass medicine bottles made last time, and there were a lot of them piled up in the backyard.

"Nothing is wrong with you. By the way, the weather is getting colder and colder. The business of glutinous rice lotus root and lotus root combination is not good, right?"

"Well, it's a lot less, but I've made the candied haws you made last time, and I've collected a lot of red fruits. There are a whole large warehouse. I'm going to start selling candied haws these days, and the weather is just right."

"Okay, go and do your business. Come here to meet me in the evening and let me know if there is any temporary arrangement to go back and notify you."

Boss Xue scratched his head and walked towards the No. 2 courtyard. Zhou Heng turned around and went to Huichuntang's backyard and headed straight to the next door of the alcohol room.

Xiao Liuzi rushed out of nowhere and blocked her from the door.

"Who? Be brave, boss!"

When I looked up, I found that it was Zhou Heng. Xiao Liuzi's turtle energy disappeared in an instant, and he instantly turned into a well-behaved child next door.

"The boss is going to go in, I'll open the door for you now."

Zhou Heng looked at him, "You kid was the guy who took the 80s last time, right?"

Xiao Liuzi nodded vigorously, "Yes, it's me, but I'm going to take the exam every seven days, why don't I take the exam? I'm still waiting for an upgrade. The boss didn't agree to me. If I had enough 80 points this time, I would let me follow Zhang Ankang as a nurse?"

Zhou Heng was amused, raised his hand and poked his head, pulling the person aside.

"Zhang Ankang and Desheng have gone to Jining. The exam has to be held waiting for everyone, so there is no more than two days. You can just review it carefully. Open the door and I want to see how Penicillium looks."

Although Xiao Liuzi was a little unwilling, he nodded quickly, opened the lock and opened the door. He had a warm breath on the pavement. It was not bad that the temperature was very suitable for the growth of Penicillium.

Zhou Heng walked into the room, opened a bucket and took a look. A layer of fine mold mycelium covered the liquid surface.

Looking back at Xiao Liuzi, Zhou Heng ordered:

"Take a bucket upstairs and deliver it to the laboratory."

Xiao Liuzi picked up the bucket and followed Zhou Heng upstairs. When he arrived at the door, he still locked the door.

After going upstairs, he put down the bucket, but Xiao Liuzi didn't leave, waiting for Zhou Heng's orders.

Zhou Heng looked at him and smiled, "I asked Achang and Zhang Ergou to come up and help together, and then put a pack of charcoal particles that had been cooked and dried last time, and prepare a bottle of rapeseed oil."

Xiao Liuzi hurried to call someone and then moved things. Soon the three of them brought a large bag of charcoal and a bottle of rapeseed oil.

Zhou Heng was wearing gloves and placed a huge sterile gauze on a basin. An iron bracket had been made on it at this moment, and four hooks could fix the gauze.

After fixing, Zhou Heng instructed Zhang Ergou to pour rapeseed oil into the barrel of penicillin culture medium, and stirred it continuously with a wooden stick. As the stirring was made, it seemed that some particles appeared on the upper layer, but I couldn't see clearly what it was.

Achang is not that restrained. After all, Zhou Heng likes to ask questions from others. If you don’t understand, you have to ask clearly in time. Achang quickly looked at Zhou Heng and asked:

"Master, why are there so many particles floating in the rapeseed oil poured into the culture medium?"

Zhou Heng smiled, "This question is good. Xiao Liuzi needs to take out a notebook to record it. We pour rapeseed oil and stir it thoroughly. It dissolves fat-soluble substances. This is wrapped in mold, and it is not something we can choose manually."

Achang suddenly realized and quickly continued, "I understand, it's like carrots. Every time Wangcai cooks with carrots, his master always asks him to put the carrots in the oil pan and stir-fry them first, saying that the fat-soluble nutrients inside will come out, and it will be good for the eyes if you eat them."

Zhou Heng nodded, "That's the same thing. OK, Zhang Ergou, stop stirring now, stop a little bit, pour out the upper layer of grease, and suck it out with a syringe if there is any residue."

Zhang Ergou moved very quickly. After the oil on the upper layer was still, he quickly found a bucket to force the oil out, and all the remaining small oil beads were sucked clean with a syringe.

Zhou Heng then ordered Xiao Liuzi to throw the steamed and disinfected activated carbon into the nutrient solution.

Seeing Zhou Heng's gesture and stirring, Zhang Ergou quickly moved. Seeing that the liquid became clear, Achang widened his eyes and quickly recorded the process.

Zhou Heng saw that it was almost done and ordered: "Snap out these charcoal particles and put them in the wooden barrel with mouths that I made."

Achang and the others quickly took action, used the power fence to remove all the charcoal particles and put them in the wooden barrel beside the window.

Zhou Heng was also very nervous at this time. After all, these are all local methods and are feasible in theory, but the actual operation is not a theory, and I don’t know if it is possible. I turned around and looked at Zhang Ergou.

"Okay, now wash it with distilled water."

Zhang Ergou put a pipe of distilled water on the edge of the bucket and used a syringe to suck the pipe.

After a moment, clear water flowed into the bucket, and several people kept shaking the bucket, and the charcoal particles were washed quickly.

Zhou Heng stood up and stood beside the bucket, pushed the particles apart, folded a stack of gauze, blocked it at the water outlet below, and then jumped down.

"Okay, ready. Now inject acidic water, then alkaline water. At the same time, use a bottle below and then, the small infusion bottle. Stop at the horizontal line, pinch the hose below, change to another bottle. Remember, work together."

The few people nodded quickly, and Zhang Ergou pinched two tubes and started to suck. The acidic water was made by Zhou Heng with vinegar. It was not as sour as expected. However, pouring it in in large quantities still made it feel a bit irritating to the eyes.

After pouring the acidic water in, start pouring the alkaline water. This is very simple. After all, it is not suitable to use a high-concentration alkali solution, so Zhou Heng chose to use seaweed to cook the juice and filter it. Now it is a clear liquid. When almost all the liquid is poured in, Zhou Heng quickly called Xiao Liuzi.

"Quickly, start bottling, Achang controls the amount, and then quickly seal it with a disinfected cork."

With Zhou Heng's instructions, the few people moved quickly. They were all people who had been making medicine all year round, and their reaction speed was very fast. Bottles of penicillin were sealed and packed in wooden boxes.

I didn’t expect to make more than 100 bottles of penicillin in this bucket of culture medium.

Zhou Heng looked at the last half bottle and waved his hand at Xiao Liuzi.

"Don't pour it down. There is not enough bottle inside. Let's do an experiment. If it works, using this to control infection will be amazing."

Achang came over and knew that the effect of using streptomycin and sulfonamide to control the plague was simply described as horror. This was simply a spiritual pill.

"Master, is this even more powerful than streptomycin and sulfadiazine, those two drugs?"

Zhou Heng nodded, "It's even better, and its application range is even wider. Streptomycin and sulfadiazine are not effective in many infections and anti-inflammatory conditions. However, it is still very effective in controlling plague and malaria. However, penicillin is different. This can be widely treated. Eighty or ninety percent of all infected diseases can be treated."
