Titled 200 million years

He originally thought it would take a lot of time for the village chief to find these things, but he didn't expect it to be so fast, it would be less than half an hour.

This can also explain a problem from another aspect, that is, the village head really hopes that this plague can be solved and the villagers can be free from this catastrophe.

He is indeed a good village head.

Xia Xun thought to himself.

Xiao Yixian glanced at the things on the wheelbarrow, raised his head and asked puzzledly: "What do you want these things for?"

"Make medicine."

Xia Xun said.

"Making medicine?????"

Countless question marks appeared on Xiaoyixian's face.

She couldn't help but took another look, and then almost retched out with nausea...

Chapter 91: Master's Master's Master (Thirdly, please subscribe to be unable to afford it)

(It looks like three shifts, but it's nine thousand words!)

Xiaoyixian is an orphan, she is the child picked up by the master from the mass grave.

Because I studied medicine with my master since I was young, I have seen many strange diseases and many nausea diseases.

This also caused her to develop a big heart different from ordinary people.

But after smelling the smell, she still couldn't help feeling a little nauseous.

She has seen in medical books that some use boy urine as medicine, some use bat shit, also known as night-blindness, and say it has the effect of curing night blindness, and some use human shit as medicine. We call gold juice...

In short, the world is full of surprises.

The master once said that all things grow and restrain each other, and there is nothing completely useless.

Mushrooms can grow on dead wood; excrement can be used as medicine; old people often say that "breaking a family is worth a thousand dollars."

But like Xia Xun, it was the first time in her life that people who took rancid steamed buns, buns, and various fruits were used to make medicine.

...

...

The place where the medicine is made is in the kitchen of Meng Qing's home, and the environment is rather primitive.

Because she wanted to teach the method to the little doctor, and then she would spread this method, so when Xia Xun was in the medicine, the little doctor was watching the whole process.

In fact, penicillin was first discovered by humans to be extracted from the mold on the rotten meat, although it sounds disgusting.

But because the mold that survives on rotting meat will not die, it is proven that it has anti-rot, anti-inflammatory and anti-bacterial effects.

Xia Xun asked the village chief to collect a lot of food such as steamed buns and buns that had been rotten and covered with hair.

First use chopsticks to scrape off the penicillium on it and put it on a plate.

Then use rice to grind into juice, and use taro to grind into juice. After the two juices are mixed, they are used as a culture solution and implanted in Penicillium for cultivation.

Normally, this training process takes seven days.

"When you do this step in the future, remember to wait seven days, otherwise you won't be able to cultivate something like penicillin."

Xia Xun specifically asked.

"Then why do you only use a few hours?"

The little doctor asked.

"Because I have mastered a special method, but this method can only be used by me, even if it is taught to you, it is useless."

Xia Xun said.

"alright."

Xiaoyixian curled his lips, looking helpless.

After penicillium is cultivated, it is extracted. Pour the culture liquid made by mixing rice juice and taro juice into the funnel, pour vegetable oil into the filtered liquid, stir it evenly, and let it stand. , Insoluble substances in the middle layer, water-soluble substances in the lower layer.

I thought that explaining these three terms would waste a lot of time, but I didn't expect Xiaoyixian to realize it all at once.

Sure enough, smart people learn everything quickly.

Penicillin is a water-soluble substance, and only the water-soluble substance needs to be extracted.

At this time, penicillin is still liquid, and it must be purified from the water.

This step is the most critical and also the most complicated step.

Xia Xun first wrote the steps on the paper, and let the little doctor read it first.

Although she knew that she should be able to look at it, but at any rate, she wrote down the steps so that she didn't look blank when she watched him operate.

Put the penicillin-dissolved water that was just extracted, and pick up a clay pot from the ground.

The clay pot is filled with charcoal powder that has been boiled and sterilized, and the penicillin solution that has just been extracted is poured into it, and gently stirred with a chopstick.

Xia Xun kept the speed to the slowest as much as possible, and explained to the little doctor fairy while operating.

Although Xiaoyixian couldn't understand this operation at all, he remembered it all in his heart.

When it was almost stirring, Xia Xun used a spoon to dig out the charcoal powder from the clay pot. The dry charcoal powder had been mixed with the penicillin solution and turned into a wet lump.

"Then put the charcoal powder into the bottle and pour boiled pure distilled water."

Xia Xun explained to the little doctor fairy while operating.

Before that, he had already introduced her to the concept of distilled water and how to extract distilled water.

"After pouring in distilled water, then pour in acidic water made with vinegar."

"Because penicillin is a weak acid substance and will not dissolve in acid water, it can further remove alkaline impurities."

"Of course, it doesn't matter if you don't understand what acidity and alkalinity are, it doesn't matter."

Xia Xun raised her head and took a look at Xiao Yixian. Seeing her frowning, she seemed a little bit painful.

"The last step is to pour the alkaline soda water, so that the penicillin will dissolve out of the charcoal powder."

Xia Xun made a hole at the bottom of the bottle, and the high-purity penicillin solution flowed out from the lower mouth, all flowing into a large bowl.

"If you do this, you will basically be done."

Xia Xun brought the bowl full of penicillin to the little doctor fairy and said to her.

"Although I don't understand this principle at all, I have all written down the steps."

Xiao Yixian said.

"Since you are a pharmacist, the steps to make penicillin should be a piece of cake for you."

Xia Xun said.

"Yeah." The little doctor nodded. Compared with refining pill, the extraction of penicillin is really not worth mentioning. It is not even one percent of the difficulty of refining pill.

She even felt that she didn't need a pharmacist, and someone who was a little more careful could draw a gourd according to the method Xia Xun taught.

"What else needs to be done next?"

"Or is it possible to treat sick patients?"

The little doctor fairy raised his head and looked at Xia Xun.

At the beginning, she did not believe that Xia Xun said that these rotten ingredients could be used to make medicines that could cure the plague, but watching Xia Xun do it step by step, and every step is alike, Xiao Yixian has slowly begun to believe that what Xia Xun said is true.

The master also told her before that she must have a broader vision and should not be limited.

Everything in the world is constantly moving forward, and so is the treatment of diseases.

Some diseases seem to be incurable now, but they may be cured in the future.

Because certain medicines will be continuously discovered and manufactured by people, the doctors will be more and more sophisticated in their medical skills, and there will be more and more treatment methods.

The master said these words by his master's master who told him, and his master told him that he would tell her these words again, hoping that she would remember them for the rest of her life.

"Theoretically, this penicillin solution can be used to save people, but in order to test whether this penicillin solution is effective, a small experiment is needed."

Xia Xun said.

"How to do this test?"

The little doctor asked.

When the master used to teach her medical skills, he often used small animals for experiments, so it is no wonder that.

Xia Xun picked up a jade plaque and said to the little doctor fairy: "It's a medium made of agar, and it is coated with Staphylococcus, or toxin, extracted from the sick patient."

He felt that it was difficult for a stranger to understand what kind of bacteria, and it would be much better if it were replaced by toxins.

"Drip the penicillin solution we just made on the toxin. Normally, you need to close the lid and wait a few days."

"After a few days, if there is no change on the surface. This means that the penicillin solution has no effect. In other words, the manufacturing has failed and needs to be restarted."

"But on the contrary, if there are circles around the dripped solution, it means that penicillin has dispelled the toxins, and this penicillin solution is effective."

Xia Xun opened the lid on the jade as he spoke.

Similarly, he used some special methods to greatly shorten this step.

The little doctor fairy came forward, bent over, and was surprised to find that a circle appeared around the dripping solution.

Eldest Miss Hong Meng Hall298316354

Although the circle was not big, it caused a huge shock to the heart of the little doctor.

"It turned out... it really succeeded."

She raised her head and looked at Xia Xun.

The clear and indifferent gaze met his eyes.

She thought that the master was already good enough, but now she felt that the master still seemed to be inferior to the young man in front of her.

"Perhaps, only the master's master's master, the old medicine elder who was famous in the Kyushu mainland more than two thousand years ago, can compare with it."

The little doctor fairy looked at Xia Xun who was standing in front of him, and couldn't help thinking like this in his heart.

ps: Some people may think this chapter is water, because many of them are popular science.But in fact, it takes several hours to read this information, which is enough to write several chapters.Try to minimize this kind of plot afterwards, it feels a bit thankless, awsl.

ps: This indigenous method of penicillin was seen in a Japanese drama called "Benevolent Medicine". It tells the story of modern doctors who traveled to ancient times and used modern medical knowledge to pretend.

Chapter 92 Give her an injection (first more seeking subscription)

What shocked Xiaoyixian was not only Xia Xun's peculiar pharmaceutical method, but also his advanced treatment concept.

The master is already a well-known genius doctor in the Kyushu Continent. His medical skills are exquisite, and he almost represents the highest level of Kyushu medical practice.

However, Xiao Yixian felt that compared with Xia Xun, he might have to go a little bit behind.

...

After extracting the penicillin, Xiaoyixian thought that he could directly use this to treat the sick villagers, but Xia Xun shook his head and said that it was still the last step.

The two of them walked out of the kitchen, the sky was completely dark, and the stars were like lights that were lit, one by one emitting a faint silver light in the dark blue night sky.

Su Wanluo squatted on the stairs outside the house and raised his head to look at the stars in the sky.

Although there are sunrises and sunsets in the small world, and the moon and stars are scarce, they are all illusions woven by magic circles, and they are not real.

"Is the medicine ready?"

Seeing Xia Xun and Xiao Yixian coming out of the kitchen, Su Wanluo stood up quickly and asked softly.

"Ok."
