Then put the charcoal into a container, filter it with distilled water, and wash off the debris.

Since penicillium is a weakly acidic substance and will not be soluble in acidic water, acidic water is made with vinegar to wash away the alkaline substance, and then alkaline water is made with soda, and penicillium is dissolved from the charcoal into the water, and the high-purity penicillin solution is prepared.

How high is penicillin suitable for humans? Since there is no means to measure the purity of penicillin, the next step is to conduct continuous experiments.

This requires some suppuration, put it in a smaller vessel for culture, dip it in a piece of paper to take penicillin liquid, put it in a small utensil to observe, if there is a circle in the place where the small piece of paper is placed, it means that this concentration of penicillin drives away the bacteria, and penicillin is effective.

Therefore, throughout this process, the difficulty of preparing penicillin is to remove impurities, otherwise the curative drug will be made into poison, and the second is to find the appropriate concentration of penicillin solution, which is a small and cumbersome process.

As soon as Fang Qiong left, the two of them hurriedly took action. Wash the pot and cut the radish, raise the fire to cook, the firewood is not dry, the yard is full of wolf smoke, Meng Zhijing is very comfortable with a nose of ash, and from time to time he smirks at the corner.

Gong Nian Huai was busy washing rice, and he cried when he bought the rice, and he was still digging it, because he saw Meng Zhijing smiling at the corner, and he was scared out of white sweat.

The two kinds of water were mixed together and left to dry, and the two of them carried the basket and shaved the green hairs from the oranges one by one. It wasn't until the two of them also became little green men that they finished processing the four baskets and a half of oranges.

The rest of the process was to put green mold in the mixture, until by the time they couldn't straighten their waists, the backyard had turned into a china shop. The two of them sat in the porcelain bush, looking at the results that had been made in the middle of the night, and only gasped down.

When Zhang Yan walked into the backyard with the food box, he thought he had gone to the wrong place, looked at the porcelain jars all over the yard in confusion for a long time, slowly retreated, looked in the front yard for a long time, and after making sure that he had not made a mistake, he walked into the backyard again. Find a gap between the porcelain jars all over the floor.

"Zhang Yan? There you are! ”

A weak voice came out of the can, Rao is bold and bold, and he was also startled by the sound from the can, and his hair stood on end.

"Who?" Zhang Yan let out a low roar, and saw two black jars grow out of the jars.

Zhang Yan's two legs hit the swing straight, and the jar became fine?

"Zhang Yan, I'm here, pull me, hey," Zhang Yan tentatively took two steps forward, only to see clearly through the faint light, two people sitting on the ground, legs wide open. A person is trying to stand up, vaguely Meng Zhijing.

"Major General?"

"It's us."

"You guys? This," Zhang Yan looked at the courtyard again, and then walked towards Meng Zhijing.

"Well, it's not bad, this is my result with Nianhuai in one night, oh, I can't straighten my waist. What to eat? "Meng Zhijing took a look, yes, Zhang Yan is here, there is no need to get up.

"Childe, you wait," Zhang Yan saw that there were two beds near the main room, put down the food box, held one in one hand, and put the two of them in front of the bed, and the two sat on the bed. The ground is too damp, and if you sit on the ground for a long time, you will hurt your body.

Zhang Yan first let the two of them drink a sip of water, and then brought two basins of water for the two to clean, and then opened the food box and put the food on the bed in the same way.

Gong Yi Nian Huai and Meng Zhijing didn't look at what kind of meal it was, picked up the bowl, and devoured it for a while.

After eating and drinking, Meng Zhijing asked Zhang Yan, "Why did you send it, Nian Huai and I are going to starve to death, we haven't been so hungry when we grow so big, this taste is really uncomfortable." ”

"Hehe, the little one is here early. But Fang Ye said, if you don't finish tossing, the small ones can't come in, so the little ones have been listening outside the courtyard wall. ”

"Hey! Uncle Fang, it's too serious. Forget it, Zhang Yan, you can go back, just guard here, I'll lie down with Nianhuai for a while. ”

Zhang Yan nodded, "Fang Ye also said so, the little one is guarding the room, and there are people patrolling outside, so the two sons can rest in peace." ”

The two of them were sleepy and tired, like the rising tide of the sea, surging in. After Zhang Yan cleaned up the dishes, the two of them fell on the bed, and after a while, snoring sounded.

A place of starlight fell all over the courtyard.

Gong Yi Nianhuai slept very soundly. Such a state of dedication to doing something has only occurred in the first three years of graduation.

Preparing the culture medium and applying green mold to the medium, most of the work was done by Meng Zhijing. Not only is Meng Zhijing's physical strength stronger than him, but his interest is much greater than his, and he is really tired and happy.

The main data of the public transmission of Nian Huai, the proportion of the two elements in the medium, the concentration of the medium, the amount of green mold smeared, etc., must be recorded one by one. And write these data on small strips of paper and glue them on the porcelain jar.

These tasks seem to be easy, but the main action is to squat down and stand up, and after a long time, the waist is as uncomfortable as if it is broken.

After six days, when the Penicillium culture has been delayed, the optimal ratio can be selected according to the development of Penicillium.

This is to continue. Green mold is like a leek, cutting one stubble and another stubble, like a rolling wheel, rolling forward every day. And so on and so forth, in a seven-day cycle, and moving forward. Penicillin is constantly being produced in this roll.

Only after a complete cycle can the best solution be selected. I can't rush if I want to.

And in the meantime, syringes have to be made. Like the tablets of later generations, the public infusion of Nianhuai can't be made, so it can only be injected intravenously.

In the Song Dynasty, there was certainly no glass, and there was no plastic, so making syringe tubes became a problem. Needles may not be a problem.

Gong Nian Huai entered the dark and sweet sleeping country with a head full of question marks, exclamation marks, and ellipses.

The chiming chicken's scream, this time the public lost Nian Huai failed, but Fang Qiong's footsteps as light as a night owl woke up the public lost Nian Huai.

"Uncle Fang is early!" Gong Nian Huai was half-lying with one arm propped up, rubbing his eyes with one hand, and yawning a long time.

Fang Qiong walked around the jar with her hands behind her back like an old hen, bending down from time to time to lift the lid and look into the jar. Hearing the sound of Gong Nian Huai, Fang Qiong straightened up, raised his head and glanced east, the sun was already lying on the wall, was it early or not?

"Nianhuai, that's it?" Fang Qiong came to Gongyi Nianhuai's bed with a jar, and glanced at Gongyi Nianhuai first, "You're still young." ”

"Uncle Fang, you can't hold the jar and dangle it, it will stun the magic medicine seeds." Gong Nian Huai jumped off the bed, Fang Qiong was fine anywhere, and rubbing against the bed at every turn made Gong Nian Huai a little uncomfortable.

"What? Can't shake it yet? When Fang Qiong heard this, she gently put the jar in her arms on the bed that Gong Nian Huai had just vacated, "It's so delicate." Nian Huai, you tell Uncle Fang, what are the taboos, Uncle Fang will show you well. ”

Gong Nian Huai stretched his waist, "Well, it's nothing, you can only look at it and don't touch it." Uncle Fang, you have to sort out the house as soon as possible, you have also seen that with such a few baskets of oranges, the yard will be paved, and there will be more and more in the future. ”

"This Uncle Fang can save it. There will be more people doing this today, so rest assured. ”

"By the way, Uncle Fang, see if this thing can be made." Gong Yi Nianhuai remembered about the syringe.

Gong Nian Huai showed Fang Qiong the picture of the syringe.

Fang Qiong casually took the drawing in Gong Nian Huai's hand, only glanced at it, clicked, his jaw dropped, his mouth was wide open, and his lips trembled and he couldn't speak.

How could a small syringe drawing surprise Fang Qiong so much?

Fang Qiong had never seen such a drawing, and she would never have imagined that the drawing could be drawn like this. This is a three-dimensional projection map, also known as a three-dimensional projection map, which is a kind of engineering drawing, although it is drawn on a flat piece of paper, it makes people feel abrupt. How could this not shock Fang Qiong.

And this is actually from the hands of a teenager and a half-year-old, is it possible that the public loser has gone against the sky to this extent?

It took a long time before Fang Qiong's lips trembled and a sentence burst out, "Nian Huai, this, what is this?" ”

"Uncle Fang, I call this a syringe, it is used for injecting people to treat diseases, you always see who can make it, and after the little nephew makes penicillin, he will use it to treat patients."

As soon as he heard that it was used to cure diseases, Fang Qiong glanced at the porcelain jars that filled the yard, and he could use moldy oranges to make medicine, and he could understand it with such a tube, oh, the syringe would be used to treat the disease, and the magic medicine still needed to use an artifact, it was matched.

Fang Qiong carefully put the drawings close to her body, and pressed them again, only then did she gather her mind, "Nian Huai, Uncle Fang will do it for you." ”

Gong Nian Huai is still not at ease, syringes are not difficult to make, the difficult thing is the material, the later generations are glass, and later used plastic disposable, these two materials are definitely not in the Song Dynasty. Gong Nian Huai didn't know what materials could replace glass and plastic in the Song Dynasty, so let Uncle Fang find someone to do it, and then use the hanging bottle to infuse, and the hose can always be made.

"Uncle Fang, the little nephew still has a drawing here, you can also take a look." Gong Yi Nianhuai took out another copy. This was drawn last night by taking advantage of the gap between Meng Zhijing's preparation of the culture medium, and Gong Nian Huai.

"Don't show it to Uncle Fang, Uncle Fang can't understand it, just tell Uncle Fang, just do what it's for." Fang Qiong learned to be obedient this time, he only glanced at it, and wanted to put it in his arms, at his age, he had already passed the stage of curiosity, but in the past two days, this half-old child had an impact on him more than most of his life. I wanted to treat Gong Yi Nianhuai with a normal heart and things that surpassed his understanding and insight, otherwise he would be shocked every time, and it would not be conducive to health preservation.
