Yuebai watched her trot to the figure in front of them and shook her head reluctantly. Sure enough, nature is like this. Even if you are determined to make a good decision, where can the ending be better? You'd better not expect too much from her.

After a long walk, they finally saw a lot of houses in the village.

When a child in a farmyard saw an outsider in the village, he desperately shouted to the house, "Mom, there are strangers in the village."

The woman wrapped in a headscarf came out of the room. When she saw the black robes they were wearing, she was happy and hurried to meet them: "I don't know, but the witches and adults are coming?"

Zi Mo nodded: "we came to this village to check the source of the disease. Aunt, you may help us provide some clues."

The peasant woman was happy: "great, God bless, several witches. My family also contracted the plague a few days ago. Please help."

Zimo and Luochen nodded and led the people into her house with the peasant woman.

In the peasant woman's house, except Gai Xiaoli, the other four witches were treated very well. The peasant woman simply regarded the four witches as gods, serving tea and snacks.

Falling dust was embarrassed and handed the tea to gai Xiaoli. Gai Xiaoli shook his hand and said, "there are patients in this family. You'd better not touch things here. I don't want five people to come. I'm the only one to go back."

The four looked at each other warily and stood up.

The woman turned her head and looked at Gai Xiaoli: "I won't harm the witches and adults. I just want to invite some people to sit down and drink some water to have a rest."

Zi Mo nodded: "the saint has no other meaning. It's better to be careful before finding the source of the disease."

The woman turned her head and looked at Gai Xiaoli, who was called the saint, with regret on her face. "It turns out that you are the saint. Just now, it was my woman who was rude and took such a noble saint as... As a servant girl."

Gai Xiaoli shook his head and smiled: "it doesn't matter. Take us to see the patient first."

The woman nodded, opened the curtain of the wing room and let several people in.

Gai Xiaoli stood at the periphery and looked at it for a few times. Seeing that the four people around him had no action, he had to ask, "why don't you go and have a look?"

Yuebai shrugged: "if we can see the way out, it won't call you out."

Gai Xiaoli was shriveled, sighed and walked forward, got close and carefully observed the patient's face.

The secretion from the patient's eyes almost covered his eyes, and there was purulent secretion from his nose. He reached out and scratched his eyes, which seemed to be accompanied by corneal perforation.

Sneeze, sneeze.

Alas, Gai Xiaoli sighed and put his hand on his forehead.

Sneeze, sneeze.

Yuebai sees that she sneezes as soon as she touches the patient's body. It feels strange, but it's hard to say anything.

Gai Xiaoli looked at the woman, "did he get fever before, and then he got fever again? Can't he eat anything now?"

The woman wiped her tears. "Yes, the high fever doesn't go away. You can't eat anything."

"How many days has he been like this?" Gai Xiaoli looked at the body and asked.

The woman replied, "it adds up to four or five days."

Gai Xiaoli is speechless. This is a typical plague. Although it mostly appears in dogs, in her opinion, there is no difference between dogs and wolves. "Do you have many such symptoms in the village now?"

"There are many people in almost every family, and many people have died. My family points to us to pick the beam. Without him, my family will be finished. Saint, you are a god man. Save our family."

As soon as the woman's hand touched gaixiaoli's leg, gaixiaoli habitually sneezed.

Gai Xiaoli wondered why she was so strange. In the past, she only sneezed when she met animal hair. What's the matter now? The woman in front of me is clearly a human body.

Gai Xiaoli broke away and said, "I'll try my best, so stop crying and stand up. I still have many questions to ask you."

The woman stood up and wiped away her tears. "Saint, just ask. As long as I know, I will answer you."

Gai Xiaoli pointed out: "do those who have died have the symptoms of twitching, foaming at the mouth, turning and collision before they die?"

The woman asked in surprise, "yes, how do you know these saints?"

This is a typical symptom of plague. She doesn't want to know, okay?

"Saint, have you got an idea? What should you do?" Lan Ying, who hasn't spoken since she came out, finally spoke.

Gaixiaoli looked back at her and almost forgot her existence.

"Yes, yes, but I'm afraid it will take some time."

"Since I know it will take some time, I can't start quickly." I still yelled at the moon white.

Gai Xiaoli shrugged. Can't this guy stop being so fierce? I can't stand her.

"First of all, we must stop the spread of the disease. Those who have died must not be exposed to corpses or buried in soil. They must all be cremated.

Secondly, for those people who are already ill, we need sodium hydroxide to eliminate the virus. Ah, sodium hydroxide is caustic soda. Is caustic soda here? "

Seeing several people looking at her blankly, Gai Xiaoli patted his head. Is it so backward.

"Yuebai, I'll teach you the production method of caustic soda. You take the villagers to do it and distribute it to everyone. In addition, all appliances at home should be wiped and disinfected with caustic soda, and then placed for a few days before reuse."

"OK, I see. How to do it?" it was the first time that Yuebai spoke to her without a disdainful roar.

Gai Xiaoli was stunned and said: "First find quicklime and baking soda. Put quicklime into water and turn it into lime slurry after lime reacts with water. Then pour baking soda into lime slurry, stir it for a while and let it stand for a while to precipitate. After precipitation, the upper clear liquid is caustic soda. Just pour it out carefully. Remember, the lime slurry must be excessive to ensure the purity of caustic soda."

Yuebai nodded, "I will do it well." then she turned and went out to summon the villagers.

When the woman heard Gai Xiaoli's method just now, she had never heard of it. She sighed in her heart, "we have met the living Buddha."

Gai Xiaoli took a puff from the corner of his mouth: "it's not as exaggerated as you said. It's just some common sense of life. By the way, you should be responsible for helping me inform the people in your village that there are no infected people. For the sake of safety, you'd better disinfect yourself with caustic soda to avoid accidentally getting sick in the future."

"Yes, yes, saint, don't worry. I will be responsible for informing you."

Gai Xiaoli turned and looked at Zimo and Luochen behind him: "the cause and method are found. You two go back to the emperor and ask him to implement my method all over the country. By the way, tell the emperor that in order to prevent the spread of pathogens again, we must send someone to supervise the burning of corpses."

After listening to gai Xiaoli's words just now, Zimo and Luochen also admire Gai Xiaoli. They bow their hands and say that they will do it properly.
