In the past few days, there is no abnormality in the quarantine area, everyone is very happy because the epidemic has been controlled, and they have recommended themselves to help decoction medicine, Lin Yuan also plans to wait for all the new drugs to arrive, she will send some of them to the quarantine area and hand them over to the people in the quarantine area to help decoction the medicine.

But the plan couldn't keep up with the changes, and there were sick people in the quarantine area.

When Lin Kite and the others arrived at the quarantine area, there was already a panic in the quarantine area, and many people began to panic because of the appearance of new infected people, and the newly ignited hope fell to the bottom.

However, after everyone saw the appearance of Lin Kite, it was like having a backbone, and suddenly their mood stabilized a lot.

Lin Yuan comforted everyone, and then began to check the pulse of the infected person.

"Miss Lin, am I really sick?" The little girl who was being taken by Lin Kite was crying, very pitiful.

"Judging by the symptoms, it is, but don't be afraid, I will cure you." Lin Kite actually doesn't have much confidence, but she must show a very confident appearance, otherwise it will only make more people panic.

The little girl nodded with red eyes: "I'm not afraid, I believe in the girl." ”

Lin Yuan checked several people who also had symptoms of the plague, and found that their symptoms were similar, that is to say, the time of infection was about the same, and they had all been infected since three days ago, but because of the prevention and suppression of herbs, their symptoms were only delayed.

Wasn't that exactly what they had been scheduled to quarantine three days ago?

Lin Yuan's sudden flash of inspiration, in the past few days, she and Zhao Yun have been worried about the source of the disease, food and water have been checked, all are no problem, but now the scope of the source of the disease has shrunk because of the quarantine area, three days ago moved into the isolation area, and those people happened to move into the isolation area on the day they began to get sick, so just ask them what they ate that day, touched something, or smelled any strange smell.

Lin Kite asked all these questions, and learned that on the day they moved into the quarantine area, they ate relief porridge and steamed buns issued by the government, and everyone also followed Lin Kite's request to have as little contact with other people as possible, so they only had contact with people in the quarantine area.

"Ahh I remembered, Sanya, didn't you drink the well water from the well in the yard? A lady suddenly said that her voice was so loud that everyone present could hear her.

The uncle next to her waved: "What nonsense? We also drank the water from the well. ”

Lin Yuan was also suspicious, because she had checked the well water in the city before and found no problems.

The eldest lady glared at the uncle: "I'm not talking nonsense!" That day, Sanya and a few people drank raw well water, and said that there was a strange smell. The water we all drank was boiled according to Miss Lin's request. ”

"But before we entered the quarantine area, we also drank water from other wells, and we also drank it raw, why are we okay?"

Now the eldest lady is in trouble.

Lin Yuan felt that since there was a controversy, it meant that there might really be a problem with the water, otherwise he would check it again.

This time, Lin Kite directly collected the water from the well in the quarantine area, and fed and drank the captured chickens every day, but only two days later, the chicken began to squint, very unenergetic, and on the third day, it lay still, and let out the last sorrowful cry in its throat.

Looking at the chickens that were gradually losing their lives, Lin Yuan's mind was even more confused, because she was very sure that the well water she had collected with Zhao Yun before was fine, but why was there a problem with the well water in this well?

Isn't the water source different?

With this question in mind, Lin Kite couldn't stay for half a second, and immediately went to the county to ask, and after the county Cheng listened to her question, he couldn't answer it for a while, so he could only take Lin Kite to find the registration record of the well.

Whoever has a well in the city, and when it is dug, needs the permission of the county government to register before digging the well.

After checking the records, Lin Kite's doubts were solved.

It turned out that there were many underground water sources in Qingmin County, but the well in the quarantine area was not the same source as the well sampled by Lin Kite last time, so one had a source of plague and the other did not.

In order to verify her conjecture, Lin Yuan went to other wells with the same water source as the well in the quarantine area to take water samples, and when she returned to her residence with the water samples, Zhao Yun was looking at her with a cold face.

Although Zhao Yun is here, there are many excerpts sent to Zhao Yun for approval every day in the capital, and Zhao Yun is really busy, so the agreement between the two at the beginning that they can't separate the distance of five steps is also null and void, because Lin Kite is like a wild horse that has escaped, and Zhao Yun can't control her at all.

I finally had time today, and I wanted to have a good talk with Lin Yuan, but I was told that there were infected people in the quarantine area, and Lin Yuan had rushed over.

Zhao Yun was really angry and worried about Lin Kite's behavior of not worrying about getting sick at all, and when he wanted to go to the quarantine area to find Lin Kite, he was entangled in government affairs again, so when he finished dealing with the new government affairs, Lin Kite had already returned.

Lin Yuan looked at his cold expression and wondered, "What's wrong?" Who you off? ”

"You."

"Me? What happened to me to you? Lin Kite was even more inexplicable, but she didn't have time to chat now, and she didn't wait for the other party to answer after asking, she waved her hand and said, "Forget it, I don't have time to coax you now, I'm busy." ”

"Zhao Yun, I seem to know where the source of the plague is."

Seeing Lin Yuan so excitedly mentioning business, no matter how much anger Zhao Yun had in his heart, he could only reluctantly extinguish himself, his beloved was busy for his country regardless of life and death, what right did he have to be angry?

After that, Lin Yuan told Zhao Yun in detail about his findings and speculations, and Zhao Yun sent someone to investigate the water sources of all wells, while Lin Yuan planned to continue her experiment, but she didn't expect that before the experiment was completed, General Guo ordered someone to send back the news.

Most of the city's water sources come from different rivers, but most of them come from the Fairy Lake. General Guo took people to the Fairy Lake to check, on the surface the Fairy Lake is no different from other lakes, but soon General Guo's people found that there were strange creatures swimming in the lake, the creatures were so small that it was difficult to see with the naked eye, and it was also thanks to the sharp-eyed soldier who found the problem that discovered the problem in the lake.

And it just so happens that the water source is the wells of the Fairy Lake, and the families around the wells are the most infected, while the wells are fed by those in other places, and almost no one is infected.

Lin Kite's experiment didn't need to be done, and he followed Zhao Yun to the Fairy Lake, and when he arrived, the soldiers were already fishing in the lake with nets to see if there would be any strange creatures.

When General Guo saw Zhao Yun and Lin Kite coming, he ordered someone to fetch a bucket of lake water, and Lin Kite squatted next to the bucket and looked at it for a long time before he saw the small insects in the clear water that were smaller than a hair.

It's scary to watch!

However, it looks terrifying, but it is still not certain that these bugs are the cause of human disease.

The soldiers had been fishing on the surface of the lake until the sun was about to set, and found nothing strange except for a strange creature's bones from the bottom of the lake.

Lin Yuan looked at the bones that were still some of the flesh that had not completely rotted and stuck to it, and the stench hit her, making her nauseous, and she retched a few times before calmly teasing the bones with a small wooden stick: "What kind of animal corpse is this?" ”

Zhao Yun shook his head, he couldn't tell the difference.

General Guo was well-informed, and after carefully distinguishing it, he said, "It seems to be an animal named Rampant." ”

"Rampant?" Lin Kite was shocked, what kind of animal is this? Isn't rampant an adjective?

"The minister only happened to see someone selling it in the frontier, the name is rampant, it is highly poisonous, it is said that only a small piece of meat can poison the tiger."

"If it's poison, why would anyone sell it?" Lin Kite didn't understand even more, this ancient murder was not short of poison, so he wouldn't have to spend money to buy this thing to poison people, right?

General Guo shook his head: "The minister is not puzzled by this matter. ”

Zhao Yun: "Since it's a frontier thing, how can it appear here?" ”

General Guo's face suddenly darkened, and he said solemnly: "Could it be ......?"

Lin Yuan looked at the solemn faces of Zhao Yun and General Guo, and knew that they were conspiratorial theories again, so he hurriedly waved his hand and said, "Although this thing has appeared in the frontier, it can't prove that it is only in the frontier, so don't worry too much." ”

"I don't know why this little beast died in the lake, could it be that he accidentally fell into it while drinking water?" Lin Kite said to herself.

Lin Kite cut open a piece of meat that was not rotten, and almost scared himself out, only to see that the meat was densely packed with wriggling small insects, exactly the same as in the lake, because there were many of them, so when they gathered together, they could see very clearly.

"I have a bold guess." Lin Kite resisted the urge to vomit, "Those insects in the lake may all come from this rampant corpse." ”

And those insects will also grow and multiply on their own in the water, which is why they will spread all over the lake.

Lin Kite felt creepy just thinking about the insects that were constantly moving in the lake, and this lake water was originally used for people to drink!

So how many insects did the people in Qingmin County drink......

In order to verify that these bugs are the culprits of the plague, Lin Kite directly picked out a bug with a clip and put it in clean water to feed the chicken, and as expected, two days later, the chicken died, with the same symptoms as the plague.

So there is no plague in Qingmin County at all, it's just that these insects have entered the human body and caused those people to get sick.

After having a clear direction, Lin Yuan can prescribe the right medicine.

She tried several schemes, and soon found a prescription that could kill these insects in the body, at first she experimented with chickens, and after the diseased chickens were successfully cured, she told the people about the medicine, and the girl named Sanya volunteered to stand up as an experimenter, and was the first to drink Lin Kite's medicine.

The effect of the medicine was very fast, Sanya began to vomit the night after drinking the medicine, spit out a pair of black and red things, the taste was fishy and smelly, and then she began to fall asleep, and when she woke up at dawn the next day, she no longer had a fever, and the number of coughs was reduced.
