Boss Zhang's house is surrounded by grassland, but the grass and trees in this grassland have withered, and there is a well not far away, and the grass and trees are also fragmented on the way from the well to this dry land.

It's like 。。。。。。 Someone fetched water from the well to water the ground, and the water was sprinkled all the way, can this poison affect even the grass and trees?

But at this time, the two had not yet discovered this strange place.

"There's something wrong with this water!" Yan Miao and Tang Su smiled at each other and said in unison.

Yan Miao and Tang Su hurriedly walked to the well, Yan Miao wanted to fetch some water to take a look, but found that he had no idea where to start.

"I, I won't fetch water." Yan Miaoqiao blushed. But I feel a little aggrieved in my heart, I'm a modern person, I've never seen a real well, if I want to say that I've seen the well that can only be the palace maid in the TV series who was thrown into the well, how can I draw water!

Yan Miao really felt embarrassed, and secretly made up her mind to learn all the life skills of this Great Liang Dynasty, otherwise she would definitely be ridiculed by someone every day in the future. Thinking of this, he stared at Tang Su seriously, determined to learn the skill of fetching water.

Hearing this, Tang Su raised his eyebrows slightly, and said with a smile: "I thought that the great servant of my palace could do anything. ”

Although Tang Su's words were a little funny, he brought a bucket of water in his hand very neatly.

Yan Miao thought angrily, I must fetch a bucket of water from the next well, and I will learn from your appearance and let you see the intelligence of this girl!

"This king knows little, you come and take a closer look." Saying that, Tang Su and Yan Miao yawned in unison.

"I didn't sleep late last year, why are you so sleepy now?" Yan Miao muttered.

"So is this king." Tang Su said this, but his eyes were staring at this well, and he had already guessed eight or nine in his heart.

Yan Miao poured the water in the bucket, and then said to Tang Su: "There is indeed a problem with this water, but it is not too serious, but the well water is not stagnant water, it flows every day, if it is calculated in this way, there is a lot of poison added to this water." ”

"So what kind of poison is this? What happens after poisoning? And how to solve it? Tang Su asked.

"It may be the poison of aconite, you first send someone to find Village Chief Zhao to ask for some mung beans, and then cook them into mung bean soup, just say that we are thirsty and want to drink. Let's see if we can get rid of the poison. Yan Miao was thinking about what to use to detoxify the poison in the well.

After hearing this, Tang Su instructed the guards to go to Zhaocun Township to boil mung bean soup, and by the way, asked the guards to ask the village chief if he felt tired recently, and if he did feel sleepy, he would ask how long it had lasted, and then ask how many wells there were in the village and where they were.

Yan Miao said that aconitum contains a variety of alkaloids, among which the toxicity of aconitum - alkali is the most obvious, there are about four:

One is a sudden increase in the heart rate, causing heart rate disorders, and the autopsy proves that the heart of the person who died of poisoning contracted like a mulberry.

Second, it can dilate blood vessels and rapidly reduce blood pressure.

The third is to affect the activity of the adrenal glands, especially to significantly reduce the content of ascorbic acid.

The fourth is to inhibit the central nervous system and the respiratory center.

Yan Miao said to Tang Su: "The manifestations of aconitum poisoning are often vomiting, diarrhea, coma, numbness in the limbs, difficulty breathing, pulse and blood pressure and body temperature drop, because the poison here is a modified aconitum poison, so it mainly makes people feel tired, but not to faint." ”

Tang Su asked, "Will drinking such water for a long time cause death?" ”

"It stands to reason that no, the main effect of this poison is to make people feel tired and drowsy, even if you drink this water for a long time, it will not cause death, it will only become drowsy. I don't know what this poisoner is having. Yan Miao said while shaking her head. There is also a way to detoxify, but you just need to drink mung bean soup for a few more days. ”

"What about the well water? Soak mung beans in well water? Tang Su asked thoughtfully.

Hearing this, Yan Miao couldn't help laughing, "You want to laugh at me, the mung bean soup we drink is to completely cook the mung beans, and then eat the mung beans together, but how many days does it take to put this kind of thing in the well water to soak the medicinal properties of mung beans?" In addition, it is easy to block the flow of water, and it is absolutely unacceptable. ”

"And what do you think?" Tang Su didn't feel embarrassed, and asked with an open face.

Yan Miao saw Tang Su's appearance at this time, but it was still a little useful, so she smiled and said: "Dried ginger and licorice, honeysuckle, mung bean, rhino horn, astragalus, yuanzhi, and milk all have certain effects. ”

"When we have drunk the mung bean soup and feel relieved, you can send someone to find dried ginger and licorice, honeysuckle, rhino horn, astragalus, and yuanzhi, and grind these into powder, and sprinkle them in the well twice a day for three consecutive days, but only if no one comes to poison them again. The efficacy of these things is almost the same, and it is not easy to affect the well water itself after grinding into powder, but the time is limited at present, so it is mixed and used. ”

Tang Su nodded, and there was a little more appreciation for Yan Miao in his eyes.

Soon, Lan Xiang came with mung bean soup, and at the same time brought the news that the village chief had indeed been sleepy a lot lately, and it had been about a week.

Yesterday, it was already noon after Lanxiang Gaoyang finished running the lap, and when he heard the news that Tang Su had gone to the suburbs of Beijing, he wanted to set off immediately, but he was delayed by trivial matters, so he rushed to the horse as soon as it was bright today.

"Zhaocun Township said that there are three wells in Zhaojia Village, all of which are owned by ancestors, and these wells are near Zhang Lao's family, Zhang Ergou's house, and Zhang Goudan's house, and these three wells belong to the wells of Zhang Goudan's family with the most people, but there is also a well shared by six villages in the suburbs of Beijing in the mountain behind the village, which is mainly used for irrigation."

"Lan Xiang, you take a few people to check all the wells in these six villages on the outskirts of Beijing, take some samples from each well, and then draw a map of the topography of the wells in the six villages for me. Let Gao Yang take a few people to check if there are any murders in other villages, and whether the people in other villages have been collectively sleepy recently. Tang Su ordered in one breath.

Yan Miao thought to herself, it seems that she will not be able to return to the capital for a while.

After the two drank the mung bean soup, they continued to check Zhang Ergou's home.

It took about a moment on the road, and both of them felt much less sleepy.

"It seems that it is indeed as you guessed, so I will arrange for someone to get the powder and throw it into the well." Tang Su said to Yan Miao.

"You are concerned about it, and now it can only be futile to solve the poisoning of the well, but you should use the poison in the well to find out who is the culprit, and then check how many places are affected, and find the root cause to detoxify."

Tang Su thought for a moment and understood what Yan Miao meant. On the one hand, water is constantly flowing, and it is really a drop in the bucket to detoxify only one poison, and the toxicity of this poison is not as strong as imagined, and it is not in a hurry. On the other hand, you can't startle the snake.
