"Lord Wang, my subordinates are farming at home, and the older generation of the family said that no matter how fertile the soil is, there will be a day when the nutrients are exhausted, and the soil also needs to rest. I think it may have been that people at that time saw that the land was fertile and kept planting paddy fields, and did not give the soil a chance to rest, so it was not suitable for planting paddy fields later. Lan Xiang replied at this time.

"If that's the case, it shouldn't have anything to do with this incident." Yan Miao said.

"It's true that what happened at that time had nothing to do with today's poisoning, but today's incident may have something to do with paddy fields. Have you ever noticed that the village seems to be planning to rebuild paddy fields? Tang Su asked.

"Huh?" Yan Miao seemed to be suddenly awakened.

Yan Miao began to think carefully, on the way from the old Zhang family with Tang Su just now, they passed by a lot of fields, and the soil ditch was dug much deeper than the usual land, as if they were preparing to repair the paddy fields.

After telling the matter, Tang Su nodded and said, "It's not stupid. ”

When the two were about to say something more, Lan Xiang stepped forward, "Lord Wang, it's not early, you haven't eaten all day today." The subordinates have already arranged for the wine and food to be prepared in the inn, so it is better to go back and eat something first. ”

As soon as Lan Xiang said this, Yan Miao noticed that the sky outside the window had darkened, and her stomach began to scream uncontrollably.

Tang Su used a fan to block the corners of his mouth that was laughing, but he didn't expect his stomach to scream.

Yan Miao laughed out loud all of a sudden, and said in her heart that she didn't expect you to have today, and then the two of them laughed at each other like children, and they didn't hide it.

Lan Xiang watched the play for a while before coughing twice and said, "It seems that the prince and Miss Yan are hungry, why don't we go back to the inn first?" ”

The two of them understood, and they both pretended to be casual and walked towards the inn.

The sky was already gone, the stars and the moon seemed to be lazy, and the night seemed to engulf people in, and several people walked towards the inn by the light of the village.

Along the way, Yan Miao followed Tang Su closely, for fear that she would lose it. Although Yan Miao, as a materialist aspiring young man in the new era, does not believe in ghosts and gods, this does not stop Yan Miao from being afraid of the dark.

In a dark night that is too quiet, the wind and grass can make people nervous, especially for Yan Miao, a person who is afraid of the dark.

Suddenly, a black shadow flashed in front of Yan Miao's eyes, Yan Miao was so frightened that she wanted to scream, and suddenly remembered that it was because there were people around her who couldn't hold back. But the muscle reaction is always much more honest than the reaction of the brain and mouth, and the moment he saw the black shadow, Yan Miao hugged Tang Su's arm tightly without even thinking about it.

"It's the cat that passed, how did you manage to be so cowardly?" Tang Su joked about her, but he didn't mind her actions at this time.

Yan Miao was still scared at this time, and her whole body stiffened for a while, and she didn't speak or let go.

Tang Su also noticed Yan Miao's strangeness, so he picked up Yan Miao and strode towards the inn. As he walked, he said, "What are you afraid of a few of us big men?" Don't you take advantage of me every day? I really don't know how you'll repay me in the future. ”

"The little woman is willing to make a promise." Lan Xiang said in his throat behind him, and Gao Yang covered his stomach and snickered after hearing it. Tang Su didn't say anything, he didn't know what he was thinking.

With that, he went to the inn.

The village chief brought a pot of hot tea and took his leave and went home.

As soon as the two of them sat at the dinner table, a guard poured hot tea for the two, and after Yan Miao drank the tea, she slowly eased up.

Tang Su didn't hold her today's matter, but said, "Let's eat first." ”

After the two of them cushioned their stomachs, Yan Miao spoke first: "Thank you for bringing me back." ”

"It doesn't matter." Tang Su didn't say anything more.

There was silence.

"Ah, I don't know what the prince thinks about the matter of repairing paddy fields." Yan Miao stiffened her head and held back such a sentence.

"I think the poisoning may have something to do with the rebuilding of the paddy fields, because the poison is not fatal, it seems to be used to delay time." Tang Su looked at Yan Miao and said.

Yan Miao said while thinking: "The villagers are usually making crops most of the time, and the biggest impact after poisoning is to make crops for a while. So if the poison was to make the villagers work less in the fields, what would it be for? ”

Hearing this, Tang Su unfolded the picture that Lan Xiang gave him today, sat next to Yan Miao, and looked at it together.

Then the two looked at each other, and at the same time pointed to the land in the back mountain and said, "If you want to rebuild the paddy fields, then this must be the first place to start." ”

Yan Miao didn't know when they had such a tacit understanding, and then asked, "Then what are you going to do?" ”

"It's hard to draw a conclusion on this point alone, and there aren't many people on this trip, so it's absolutely impossible to take care of them all." Tang Su said.

"That's what I thought, why don't we go and test the water we got back today before we make a plan?" Yan Miao proposed.

So, the two of them went back to their rooms to check and compare the fourteen water samples that the guards had brought back today.

After testing, Yan Miao found that the water toxicity of the well in the back mountain was the strongest, and the farther away from the back mountain, the weaker the toxicity, that is to say, the well in the back mountain may be the place where the medicine was directly applied, but this does not rule out that other wells were not directly poisoned.

At this time, Tang Su suddenly asked, "Is the poison of aconitum useful to plants and trees?" ”

"It's useless." Yan Miao answered without even thinking about it.

"Then today's old Zhang's grass must not be poisoned by aconitum head?" Tang Su asked Yan Miao.

"Aconitum has an effect on animals and people, but it has no effect on plants and trees." After saying this, Yan Miao thought of something strange.

"It seems that someone wants us to find out that there is something wrong with the well water." Tang Su was thoughtful.

Yan Miao always felt that something was wrong at this time. said: "Although I also know some medical skills, but I am only a half-baked doctor, although I can detect this aconitum poison, but I can only speculate on the toxicity according to the record in the book for detoxification." ”

"We've been here for two days, and if it's because of the well water poisoning, it's only two days at most, but today we're tired, could it be more serious than you think?" Tang Su questioned.

"Oh, it's broken!" Yan Miao patted her head, blaming herself for having too little knowledge and thoughtlessness, she had more contact with the dead on weekdays, and she paid little attention to the daily treatment of poisoning. If Tang Su hadn't raised this question, I'm afraid it would have been a bad thing for him.

"It was my negligence, I used to check the poisoning of corpses, but I didn't expect to encounter the poisoning of living people today, but I didn't think about it. As you said, this poison should be a lot worse than I thought. Yan Miao's face was much more solemn.
