Although they were tired like this the day before, everyone still got up early the next morning.

Yesterday, Situ Chenyi and they turned around all day, and they didn't find any problems, even if they went to see the water quality according to what Yun Wanqing said, they didn't find anything wrong. So today, they didn't go into the village to look for it, but all stayed in the city, wanting to say that when the matter here was almost dealt with, they would go together to find out the reason. Yun Wanqing has studied medicine for many years, and she should be more able to find problems in this regard.

Yun Wanqing and Bingyan were separated from each other to diagnose and treat everyone, although there were many people, but Yun Wanqing and their speed were also very fast, and when it was night, they finally finished reading them all. Fortunately, these villagers are relatively mild in the epidemic, and they will get better if they drink a few doses of medicine, and many of them are scared of themselves. It's like that God's blessing, he is actually the lightest in this, but it just happens to be injured and feverish, which will cause everyone to think that he is about to die.

The diagnosis and treatment of the patients here was completed, and early the next morning, Yun Wanqing and the others ran to the village non-stop to find the source of the plague.

Yun Wanqing always felt that the problem of this plague was on the water, just imagine, most of the people in a village are infected, and the spread rate is so fast, only water has such a possibility.

Therefore, as soon as Yun Wanqing entered the village, she followed the direction of the water flow and went to the source of the water. But even though she has reached the source, Yun Wanqing still hasn't found any problems, and there can be no problem with this water.

Yun Wanqing couldn't help but wonder if she had made a mistake, and stood by the water and thought.

Yun Ziheng has been really tired these days, and seeing that Yun Wanqing was standing there without moving, he immediately found a random place to sit down. He tapped his legs vigorously with his hands, and muttered in his mouth, "My legs are going to break, and the water in their village is too far away from the village, so it's not convenient to use water in ordinary times." This source is even more outrageous, and I have to have martial arts, otherwise I would be exhausted to death. ”

When Yun Wanqing heard his words, something flashed quickly in her mind, but the speed was too fast, and she didn't catch it all of a sudden.

"Fourth brother, you repeat what you just said, speak slowly, I didn't hear clearly. Yun Wanqing said to Yun Ziheng.

Yun Ziheng was stunned, he just complained casually, Qing'er didn't need to be so serious and let him repeat it. But looking at Yun Wanqing's appearance, she also knew that she was not joking, Yun Ziheng had no choice but to say it loudly again.

Yun Wanqing listened to his words, looked at He County Order and said, "He County Order, do the villagers have to travel so far to fight every time they use water?"

He Xianling shook his head and said, "Of course not, it's too inconvenient to be so far away." In order to facilitate the use of water, the villagers have several large tanks for storing water at home, and they fill them all at one time and come to fetch water when they run out. This village is the only one far from the river, and most of the other villages are by the river, so there is no need to be so troublesome. ”

Yun Wanqing nodded and said that she understood, this era is not as modern as modern, they all use tap water or something, and all the water is picked up in the river. But even so, as long as there is no problem with the water quality, it will be unclean at most if it is placed at home for a few days, and it should have nothing to do with the plague.

In any case, Yun Wanqing was going to go to the village to have a look, and she couldn't find any useful information here, so she naturally had to change directions.

Everyone came to the village again under the leadership of He County's order, and now all the villagers have gone to the town, so there is no one in the village.

Yun Wanqing walked to the nearest house, looked around casually, and found no problems, including the water tank, she also looked at it, and there was no problem at all. But if all is well, what is the cause of this plague?

Yun Wanqing had no clue at all, so she could only wander around the village, without a destination, just to look around and see if she could find a breakthrough.

Yun Wanqing stood on a high place, seeing that the fields in the distance were now deserted, and she was dissatisfied and a little sad in her heart. These villagers should have been self-sufficient, although not to mention how good their lives were, at least they could eat enough. But because of this drought, they had to start all over again.

Situ Chenyi obviously knew what Yun Wanqing was thinking, and stepped forward and gently patted her shoulder and comforted, "Qing'er, don't think too much, as long as these villagers can save their lives, I believe they will get better slowly." ”

Yun Wanqing sighed and said, "Our granary has finally become richer, and after this incident, I'm afraid it will be empty again." Brother Chenyi, after you go back, discuss with the emperor and open a warehouse to release grain. After this incident, it is estimated that these fields will need to be well taken care of in order to grow high-yield grain. ”

Situ Chenyi also had an idea, nodded and said, "Don't worry, when I return to the palace, I will tell the imperial brother the first thing." If the food is gone, it can be replanted, but if the person is gone, he will not be able to find it back. ”

He Xianling, who was on the side, listened to the two of them talking, and his heart was moved. Fortunately, the current emperor and the six princes are all people who have the people in their hearts, otherwise, these ordinary people really have only one way to die.

Yun Zixuan interjected and said, "Fortunately, the food before the drought has been saved, otherwise, even if all the grain in the granary is taken out, it will be far from enough." ”

He Xianling nodded on the side and said, "Yes, thanks to the wisdom of the princess of the country, she thought of such a method, not only did she save the food, but when the drought was most difficult, the rain was used by the villagers to eat, and it also saved their lives." ”

When Yun Wanqing heard this, she immediately turned around and looked at He Xianling in shock and said, "What did you say, those water villagers used it for food?"

He Xianling didn't know why she was so excited, so she nodded stunned, "Yes, there was no water at that time, this water can save your life, everyone must drink it." As far as I know, this is the case in many places. ”

Yun Wanqing didn't pay attention to him anymore, but kept walking around thinking about something, and everyone didn't dare to disturb her.

After a long while, Yun Wanqing said to He Xianling, "Then is there any rain left?" Take me to see it." ”

He Xianling nodded, "There are some that have been left in that pond, not far from there." ”

Yun Wanqing didn't say a word, and ran directly to the pool quickly, and everyone didn't know why, so they all ran behind her.

Yun Wanqing asked Chu Qiao to bring up some rain, looked at it carefully, and said softly, "Sure enough, the source of this plague is from this rain." No wonder so many people contracted the plague so quickly, it turned out that they all drank this water. It is only because the incubation period of this plague is different in everyone that it will cause everyone to get sick in batches. And none of the people in the town ate this rainwater, so they didn't do anything at all. ”

Yun Wanqing blamed herself a little, if it weren't for the method she thought of, everyone wouldn't have been infected with the plague at all. She should have made it clear to everyone that this water can be used to irrigate food, but it is not possible to use it for food. There are too many bacteria on it, and the storage time is too long, and the average farmer drinks it directly, without high-temperature sterilization, no wonder there is such a problem.

Everyone behind her looked surprised, but they didn't expect the problem to be because of the rain.

"Qing'er, don't think too much, this plague has nothing to do with you, your original intention is to save these grains, so as to save the lives of these people. You didn't expect anything like this to happen. Situ Chenyi saw Yun Wanqing's self-blame at a glance, and comforted her softly.

Yun Wanqing sat on a rock, holding her feet with both hands and said guiltily, "But if I hadn't proposed to store rainwater, these villagers would not have been infected with the plague, it's all my fault, and those who died were all because of my momentary negligence." ”

Situ Chenyi frowned and said, "Qing'er, don't drill the horns, this matter has nothing to do with you at all." You are not allowed to think wildly. ”

He Xianling and the others were already stunned, they didn't expect that the veiled woman in front of them was the princess of the country in his mouth. If you think about it carefully, besides her, who else can work so tirelessly to help these ordinary people?

He was so stupid that he should have thought of it a long time ago. It is rumored that the six princes' favorite is the princess who protects the country, and promises to marry no one except the princess of the protector for the rest of his life. He should have thought of it when he saw the two being so close, but he thought it was a rumor that something had gone wrong, and he didn't dare to think that a woman from the princess of the country would come here in danger.

Situ Chenyi and the others didn't care about He County's thoughts at all, they just wanted to quickly persuade Yun Wanqing not to think about it and take this matter on themselves. She'll be guilty for the rest of her life.
