"Yes, and it's a big deal." The anxiety on Zhang Bao's face became more intense, and he let go of Feng Yong, feeling a little anxious.

"He contracted the miasma a few days ago. Before he returned, he told me that you might have a way to cure him, so he wanted to go back to Jincheng to find you. Now you are here, and he can't find you when he goes back, so what will happen?

good?"

Hearing this, Feng Yong's heart sank, and he asked with a sense of luck, "What are the symptoms of the miasma that Zhang Junhou has?"

"First I feel weak, then I have chills, then I have a high fever that doesn't go away, and then I feel like a normal person after I sweat profusely."

"How often do you send it? Is it a day?"

After hearing this, Feng Yong felt even heavier and asked.

There are many kinds of miasma in Nanzhong, but falciparum malaria and daytime malaria are the most common.

From Zhang Bao's description, it was clear that it was daytime malaria.

"You really know!"

Zhang Bao was overjoyed and asked, "Do you have a cure?"

I have a damn cure!

Feng Yong's face was so gloomy that he almost shed tears.

The joy of the barbarian soldiers' retreat was instantly wiped out.

For the treatment of malaria, artemisinin is the first choice and cinchona is the second choice.

Don't even think about the latter, because that thing is native to South America, unless Feng Yong can really row a boat without oars, relying entirely on waves, and directly across the Pacific Ocean...

As for the former, it is as deeply patriotic as the tung tree - only the artemisinin content of Artemisia annua grown in southwest China in the world is valuable for extraction.

When Feng Yong was debating with others on the Internet, he looked through a lot of information, and he knew everything about artemisinin.

This thing is not soluble in water at all, and will decompose when exposed to heat.

So if you want to use cold water to make the concoction, or if you want to use the traditional method to make the concoction, forget it.

To get it, you still have to use organic solvents.

Organic solvents are not a problem. After all, ethanol is also an organic solvent. Therefore, before going south, Feng Yong specially made high-strength wine and soaked Artemisia annua along the way. The concentration of artemisinin in it should be sufficient.

But this thing has to be physically extracted in the end!

In future generations, even at home, as long as he is willing to spend time and money, he can find a way to produce artemisinin crystals.

But this is ancient times!

Well, in fact, if physical extraction had to be done hard in ancient times, it could actually be done, and it would only consume some manpower and material resources.

It doesn't matter if the purity is not enough. If the quality is not enough, you can make up for it with quantity. It's not a big deal.

But the injection is the biggest problem!

Because if you drink artemisinin soaked in wine directly like Feng Yong did, the effect will be much weaker than direct injection, and the concentration in the human body may not reach the standard for killing malaria parasites.

The oral artemisinin of later generations is actually a derivative of naturally extracted artemisinin.

So although Feng Yong made preparations early and used wine to produce artemisinin, it was just a test product!

After all, malaria in Nanzhong is so famous. To colonize Nanzhong, you have to deal with malaria. So he planned to use some prisoners of war for human experiments, but he never thought that he would use his uncle to practice his skills...

Because this is too much of a gamble on character.

And it’s a gamble on character where you lose more and win less.

Holding the wine brewed with artemisinin, he felt comforted, but if he really took it to bet on the erratic probability, Feng Yong would be quite disgusted.

Seeing Feng Yong's gloomy face that was almost dripping with water, Zhang Bao's excitement was like a bucket of cold water being poured on his head.

"You...can't you?"

Who the hell says can’t do it?

When your sister grows up, ask her to come to me and look at the goldfish to see if I can do it!

Feng Yong was so irritable that he let out a "tsk" sound and said angrily, "Before going south, didn't I ask Sanniang to tell him how to prevent miasma? How could he still be infected with such a nasty disease?"

Yo ho!

Do you know who you are talking to?

Dare you use such a tone?

Zhang Bao then said in a panicked tone, "Listen, I just accidentally got bitten by the mosquito..."

He looked a bit like a child who had done something wrong.

"Anguo later regretted it and said he should have paid more attention."

Everyone quietly watched Feng Langjun teach Zhang Junhou...

Malaria is like a ghost seeking life. Ordinary people would not dare to hear such things.

Now when they heard Zhang Bao say that Feng Yong might have a cure, they all listened with bated breath, fearing that they would miss a word if they coughed.

Even Wang Ping, who had come down from the city wall and wanted to meet Feng Yong and his party, quietly stood aside and became a quiet bystander.

On the other hand, a tall Yi general behind him looked at everything in front of him with a look of horror on his face, wondering... Could it be possible... is the theory about the reincarnation of the Ghost King true?

Otherwise, how could he possibly subdue the ghost that was seeking his life?

Feng Yong raised his head and let out a long sigh, the sky rumbled again, and big raindrops finally fell.

A few drops happened to fall into the mouth of Feng Tubao, who opened his mouth to the sky, causing him to vomit out the rainwater in his mouth. Then he said quietly, "It's thundering and raining. Let's go back first."

Take shelter from the rain."

Everyone was waiting for him to say something about whether he could be cured. Unexpectedly, after posing for a long time, he actually said such a sentence. At that moment, everyone almost ducked.

Zhang Bao had been a grandson for a long time, but he was not willing to give up easily when he received such a sentence. He immediately grabbed his hand anxiously and angrily, "You haven't said yet whether you can cure Anguo!"

Feng Yong sighed again, "I can only say that I try my best to treat such a serious disease. As for whether it can be cured, it still depends on God's will."

At the same time, I finally realized that no wonder the history books said that Guan Xing died in these two or three years. It turned out that he contracted malaria during the Southern Expedition.

Malaria can not only torture people to the point of death, but it was also a terminal disease in ancient times.

Thinking of this, he remembered again that this flower... seemed to have died in the past few years?

With this thought in his mind, he frowned again and looked at Zhang Bao with a strange look.

"You... why are you looking at me like this?"

Thinking of the vicious and clever rumors about this guy in front of him, and then seeing him looking at him like this, Zhang Bao suddenly felt a little nervous.

I don’t know if there was something wrong with Zhang Fei’s posture when he and Xiahou had a baby.

Both of the daughters of the Zhang family are exquisite and have a clear heart.

Zhang Xingcai has a plan.

Zhang Xingyi had black water in his abdomen.

When it came to Zhang Bao, his talent in martial arts was greatly improved. No one among his peers could match him, but he was a person with a clear mind.
