Although the light of the fire fold is very dim and it is impossible to see through, there is no doubt that the corpses are piles of corpses.

Zhao Wantong raised the fire fold high, and unrecognizable faces appeared in front of him.

"That's the source of the disease."

Wei Qing had never been on the battlefield, and he couldn't accept it all of a sudden. And Zhao Wantong is a doctor, and the first day of his internship was to guard the corpse in the morgue. In addition to other surgeries in the future, she has seen too much.

She looked closer, Wei Qing wanted to stop Zhao Wantong but had already walked to the corpse. Looking at the level of decay and the surrounding environment, "it seems that it has been dead for quite a long time." ”

Behind the corpse was already the end of the hole, and the two stayed for a while and quickly evacuated.

As soon as they came out, several teenagers came up to them and said, "Did you find anything?" ”

Zhao Wantong said: "Haven't you explored this cave?" ”

The teenagers scratched their heads and said, "It's true, I just think that there is water here and it doesn't make a difference." I thought it was flowing down from the mountain through a hole. ”

After a moment of silence, one of the teenagers exclaimed, "Could it be... Is there a problem with this water? ”

Zhao Wantong nodded, and their faces turned green all of a sudden. Because just now they washed their faces with water and drank two more sips, which is really...

Zhao Wantong said: "There are mountains of corpses in this cave, and the time of decay is impossible to verify. Decomposing corpses, you should also know that if you don't deal with them, bacteria will develop. It is very likely that the reason why you are sick is because of the water. You've all drunk the water here, right? ”

The teenagers nodded, their faces even more indescribably blue.

After figuring out the cause of the water, the group rushed back to the village. As soon as he arrived at the entrance of the village, Zhao Wantong saw Liu Che sitting in the middle of a group of children talking and laughing with them, and he was wearing a wreath woven of grass on his head.

Zhao Wantong shook his head, wanted to laugh and walked over with a serious face.

Through the mixing of storytelling, Liu Che has completely mastered the names of this group of children. Yesterday, the little girl's name was Xiaohua, and she had two younger brothers, one named Huan and one called Zhao. There are others, because although I have said it, they are all names without surnames, and Liu Che is a little unwell, so he can't remember clearly.

Not long after telling a story, Zhao climbed on Liu Che's lap again. rubbed the ash on his face one by one on Liu Che's clean brocade clothes, and said with a smile: "Big brother! Big brother! Let's talk about one more! ”

Xiaohua also came over, "Let's talk about one more!" ”

Liu Che scratched his head and hesitated, and suddenly a mocking voice sounded behind him.

"Big brother, let's talk about one more one."

Zhao Wantong approached, leaned down and sat next to Liu Che, Xiaohua and they saw that it was Zhao Wantong coming, and they all left Liu Che and threw themselves into Zhao Wantong's arms.

Zhao Wantong smiled: "Look at you, okay." ”

Liu Che glanced at Zhao Wantong and asked, "Is the investigation clear?" ”

"That's nature, who am I, isn't it!" Zhao Wantong didn't look at Liu Che, and pinched Xiaohua's face with both hands.

Xiaohua puffed out her cheeks, her face was rubbed around, and she said, "Sister...... Hmm"

"The result?" Liu Che continued.

"It's a problem with the water source, but it's actually okay." Zhao Wantong said with a smile. Liu Che was puzzled by her confidence: "Do you have a countermeasure?" ”

Zhao Wantong said: "That's." ”

Although the illness of these villagers seems to be serious, without the precise equipment of the hospital, Zhao Wantong actually does not dare to guarantee what kind of illness they are. But as long as she takes the right medicine, she thinks it should be okay.

The mountain is too high, and Zhao Wantong and the others don't want to go out of the mountain to buy medicinal herbs at the pharmacy. Therefore, Zhao Wantong chose to collect medicine on the spot, which is also a coincidence. The medicinal herbs on this mountain are still quite abundant, maybe these villagers have not read the book and don't know that they have not touched it.

In this way, those medicinal herbs have more effective years. But the first thing should not be to collect medicine, but to filter the water to turn the undrinkable water into clean and drinkable water.

Zhao Wantong said that he wanted to impress Liu Che, and Wei Qing was also very curious. She told the boys to go to the river and fetch water back with wooden buckets.

Then make a fire out of wood and let it burn thoroughly. The burned wood is then covered with earth and dug up after a few hours. Wait until it has cooled thoroughly before knocking it into small pieces.

Zhao Wantong asked them to find two wooden barrels, one of which made a hole in the side. Zhao Wantong got another clean cloth and spread the bottom of the bucket, and then spread a layer of charcoal on the cloth and spread pebbles, sand and cloth on the charcoal.

Finally, ask the teenagers to pour the dirty water into the bucket.

The villagers looked at each other strangely, and Xiaohua asked, "What is my sister doing?" ”

Zhao Wantong smiled: "Clean the water." ”

The first time, the water was still cloudy, and then it was repeated two or three times and it became clean! Liu Che and Wei Qing, including the villagers, thought it was a miracle!

Those teenagers looked like they were about to drink the clean water, but Zhao Wantong stopped them with one hand and said, "You have to boil it before drinking, and ensure that it is fully disinfected." ”

"Oh oh oh, good!" The teenagers replied hesitantly, but their faces were full of smiles.

Wei Qing approached and said, "Why?" ”

Zhao Wantong replied: "What why? ”

Wei Qing pointed to the clean water: "Why did it become clean?" ”

Zhao Wantong smiled: "Guess! ”

After solving the water problem, Zhao Wantong will move on to the next step. Originally, the villagers were worried about them, but Zhao Wantong's miracle made them the object of worship all of a sudden, and she couldn't help but say that she went to collect medicine, and a bunch of people were arguing to go with her.

It's a pity that Zhao Wantong said: "Do you know medicine?" They all shook their heads, confused.

She added: "So, boil water at home honestly!" ”

Liu Che was unwell and shirked this trip again. So this time there were only Wei Qing and Zhao Wantong, Zhao Wantong was carrying a bamboo basket in front, and Wei Qing was in the back.

The summer sun is harsh and hot, but the mountains are full of greenery. The height of each tree was more than ten meters, and it was just after noon after they were busy with that.

There are many kinds of medicinal herbs on the ground, but not all of them are needed. According to Zhao Wantong's observation, they all have diarrhea, high fever, cough and the like.

Water can be said to be the main reason, and of course it is also in terms of their diet. I remembered the appearance of the grandmother and Xiaohua for the first time, and then looked at these after entering the village. They are afraid that they have not eaten a few full meals, and the food is not good.

However, to take the medicine, you must first eat enough. So Zhao Wantong also planted some wild vegetables along the way, and she hummed a little song.

Wei Qing was silent in the back, and suddenly he said, "Don't go too far." ”

"Huh?" Zhao Wantong looked at him, "I know!" ”

As soon as he finished saying this, Zhao Wantong jumped forward two steps and suddenly his feet were empty, and Wei Qing immediately stepped forward to grab it. It's just that suddenly, the two of them rolled down together.
