Sending away Desheng and the others, Zhou Heng stood in place and sighed, and Boss Xue poked his arm.

"What's the matter, sigh, this doesn't look like you?"

Zhou Heng shook his head and looked in the direction of the second floor.

"Lord Zhang has been away for more than ten days, and the capital doesn't know how the progress is, although the Jinan Mansion has allocated two silver for disaster relief, you see that Lord Liu doesn't seem to have any smile, only the silver two have no paperwork, what is this, is it an advance? Everything is just to see the face of Lord Zhang Fuling, and how to deal with it in the future depends on the investigation on Lord Zhang's side. ”

Boss Xue raised his chin and said: "Why do you want to do so much, even if Jinan Mansion is unhappy, the silver has to be sent, as for Lord Zhang Fuling, that is a person worthy of admiration, I don't know how many interceptions I encountered all the way back to Beijing, it is not easy to have this persistence." ”

Zhou Heng nodded, "That's right, so we have to be prepared and try our best to save this chief guard." ”

With a smile on his face, Boss Xue stepped closer.

"Tell me, what am I doing?"

Zhou Heng looked him up and down, as if he really didn't need to do anything in front of Boss Xue, those small glass medicine bottles, there were still thousands of them made last time, and there were a lot of them in the backyard.

"It's nothing to do without you, by the way, the weather is getting colder and colder, and the business of glutinous rice lotus and lotus root is not good, right?"

"Well, it's really a lot less, but I have already asked people to make the sugar gourd you made last time, and I have also collected a lot of red fruits, and the whole big warehouse is there, I am going to start selling sugar gourds in the next few days, and the weather is just right."

"Okay, let's go get busy with you, come over and meet in the evening, and I'll be notified of any temporary arrangements."

Boss Xue scratched his head and walked towards the second courtyard, Zhou Heng turned around and went to the backyard of the Rejuvenation Hall and went straight to the next door to the alcohol room.

Xiao Liuzi came out of nowhere and blocked directly to the door.

"Who? Courageous...... Ah, boss! ”

When he raised his eyes, he found that it was Zhou Heng, and the spirit of the little sixth son was instantly gone, and he became a well-behaved child next door in seconds.

"The boss wants to go in, so I'll open the door for you."

Zhou Heng looked at him, "Your kid is the guy who scored eighty points in the last exam, right?" ”

Xiao Liuzi nodded vigorously, "Well, it's me, but I said that I would take the exam every seven days, why don't I take the test, I'm still waiting for the upgrade, didn't the boss promise me, if I get enough 80 points in the exam this time, let me follow Zhang Ankang as a nurse?" ”

Zhou Heng was amused, raised his hand to poke his head, and pulled the person aside.

"Zhang Ankang and Desheng have gone to Jining, and the exam has to wait for everyone, so at least not in two days, you just need to review well, open the door and I want to see how Penicillium grows."

Although Xiao Liuzi was a little unwilling, he nodded quickly, and quickly opened the lock, pushed the door open, and there was a warm breath on the surface, which was not bad, and this temperature was very suitable for the growth of Penicillium.

Zhou Heng walked into the room, opened a bucket and looked at it, a layer of fine mold mycelium covered the surface of the liquid.

Turning around to look at Xiao Liuzi, Zhou Heng commanded:

"Carry a bucket upstairs and send it to the lab."

Xiao Liuzi picked up the bucket and followed Zhou Heng upstairs, and didn't forget to lock the door when he got to the door.

went upstairs and put the bucket down, Xiao Liuzi didn't leave, waiting for Zhou Heng's orders.

Zhou Heng looked at him and smiled, "Ask Ah Chang and Zhang Ergou to come up and help together, and then bring a package of charcoal grains that were boiled and dried last time, and prepare a bottle of rapeseed oil." ”

Xiao Liuzi hurriedly went to call someone, and then moved things, and soon the three of them brought up a large bag of charcoal and a bottle of rapeseed oil.

Zhou Heng wore gloves and put a huge sterile gauze on top of a basin, which had already made an iron bracket at the moment, and there were four hooks to fix the gauze.

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

Ah Chang is not so restrained, after all, Zhou Heng likes others to ask questions, and if he doesn't understand, he should ask clearly in time, Ah Chang hurriedly looked at Zhou Heng and asked:

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

Zhou Heng smiled, "That's a good question, Xiao Liuzi wants to take out a notebook to record, we pour in rapeseed oil and stir it thoroughly, it is to dissolve fat-soluble substances, this is wrapped in mold, not something we can manually pick out." ”

Ah Chang came to his senses, and hurriedly said: "I understand, just like carrots, every time Wangcai stir-fries with carrots, Shizun always asks him to stir-fry the carrots in the oil pot first, saying that in this way, the fat-soluble nutrients in it will come out, and eating it is good for the eyes." ”

Zhou Heng nodded, "That's right, it's the same thing, okay Zhang Ergou, now stop stirring, stop a little, pour out the upper layer of grease, if there is any residue, use a syringe to suck it out." ”

Zhang Ergou's movements were very fast, and after the oil in the upper layer was still, he hurriedly found a bucket to force the oil out, and the remaining small oil beads were also sucked clean with a syringe.

Only then did Zhou Heng instruct Xiao Liuzi to throw the steamed and sterilized activated charcoal into the nutrient solution.

Zhang Ergou saw Zhou Heng's stirring action, and hurriedly moved, seeing that these liquids became clear, Ah Chang's eyes widened and hurriedly recorded the process.

Zhou Heng saw that it was almost over, and ordered: "Fish out these charcoal grains and put them in the wooden barrel with mouths up and down that I made." ”

Ah Chang and the others hurriedly took action, fished out all these charcoal grains with a fence, and put them in the wooden barrel by the window.

Zhou Heng was also very nervous at this time, after all, these are local methods, which are theoretically feasible, but the actual operation is not a theory, and he doesn't know if it will work, so he turned around and looked at Zhang Ergou.

"Alright, now wash it with distilled water."

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

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

Zhou Heng got up and stood by the bucket, pushed the particles away, folded a stack of gauze, blocked the water outlet below, and then jumped down.

"Okay, ready, now fill in acidic water, then alkaline water, and at the same time connect the bottle underneath, which is the small infusion bottle, stop at the position of the horizontal line, pinch the hose underneath, replace the next bottle, remember, to work together."

Several people nodded hurriedly, Zhang Ergou pinched the two tubes and began to suck, these acidic water, which Zhou Heng made with vinegar, was not as sour as he imagined, but he still felt a little irritating to his eyes when he poured it in large quantities.

After pouring acidic water, start pouring alkaline water, this is very simple, after all, it is not suitable to use a high-concentration alkaline solution, so Zhou Heng chose to filter the seaweed after boiling the juice, and now it is a clear liquid, when the liquid is almost poured in, Zhou Heng hurriedly called Xiao Liuzi.

"Quick, start bottling, Ah Chang controls the amount, and then quickly seals it with a sterilized cork."

With Zhou Heng's instructions, several people moved quickly, all of them were perennial pharmaceutical people, and their reaction speed was very fast, and the bottles of penicillin were sealed and packed in wooden boxes.

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

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

"Don't pour it, there's not enough bottle in it, hurry up and let's do a test, if it works, use this to control the infection, the effect will be very amazing."

Ah Chang came over, he knew that the previous use of streptomycin and sulfonamides, the effect of controlling the plague, it was simply terrifying, this was simply a elixir.

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

Zhou Heng nodded, "It is more than that, the scope of application is more extensive, streptomycin and sulfadiazine have no obvious effect on many infections and anti-inflammatory, but the control of plague and malaria is still very effective, but penicillin is different, this can be widely treated, and all infected diseases can be treated." ”

Ah Chang gasped, picked up a small bottle and took a closer look, this thing is a bottle of transparent water, if according to what Zhou Heng said, it is simply too scary, isn't it possible to treat many diseases?
