"Well, I've asked Bi to find it. I'm going to vaccinate everyone."

"Vaccinations?"

Zuo pianfan's hand was stiff and his face had no less than five expressions. He asked back at the first time.

"Well, take out a little pus from the acne scab and inoculate it on healthy people to make people immune to smallpox first. That's how my master saved people before."

Yao Sisi said confidently. In order to let Zuo pianfan accept it, she specially added a lie.

This is too absurd. Zuo pianfan is also skeptical. If others say it, I'm afraid he won't believe it at all, but this is what Yao Sisi said. Zuo pianfan has witnessed many miracles, so he believes half of this shocking practice. As for completely believing it, he can't do it.

"I hope Bi can find some patients with cowpox as soon as possible. Come here!"

"Si'er, people with cowpox..."

Zuo pianfan wanted to talk and stopped, looking like she wanted to know the answer.

"It's used to make vaccines. Oh! I can't tell at once. You'll understand it early tomorrow morning."

Yao Sisi really doesn't want to explain. She's really tired of explaining problems.

Zuo pianfan thought Yao Sisi was angry. He quickly suppressed his curiosity and followed his strong doubts. He took Yao Sisi to the peasant woman's house. "Well, Si'er, go back. Anyway, I just hope you don't get infected with the epidemic."

"Don't worry, I want to save my life and enjoy a better life. You, ah, vaccinate together tomorrow. Oh, I'm so hungry. I haven't eaten breakfast yet!"

Bi came back in the evening and brought back five people. Yao Sisi had to praise Bi, and then waited until tomorrow morning.

The next day, just after breakfast, all the villagers came except yesterday. The army counted the number of people and respectfully came to Yao Sisi, "girl, everyone is here."

"Well, thank you."

Yao Sisi said conditionally.

“……”

The army was stunned. Even if he was stupid, he could see that Yao Sisi was not an ordinary person. He was either rich or expensive. How dare he expect her to thank him? But he heard it. He found the answer from the stunned forehead and face of other people present. It was true.

"What's so amazing? Of course you have to say thank you for helping me."

Yao Sisi continued: "I'll vaccinate you against smallpox later. You can ask if you have any questions now."

Of course, Yao Sisi doesn't like answering questions, but if these people don't ask clearly first, how can it go smoothly later, so he has to be patient.

All of a sudden, there was a lot of noise.

"I've never heard that cowpox can prevent smallpox."

"Don't you want to die yourself? You can't get smallpox, but cowpox."

"Girl, how do you want to harm people?"

Although a person kept his voice very low, these whispers still floated to Yao Sisi and Zuo pianfan's ears. Zuo pianfan's face was cold, a pair of eyes waited for a circle, and the voice below immediately disappeared.

"Harm people? I'm saving people!"

Yao Sisi felt that he was wronged. His kindness was not rewarded. The dog bit LV Dongbin and didn't know the good people. Why should I bear the mistake of thinking about beauty? I hate being wronged by others in my life. Thinking of her, she couldn't help but want to ignore it, and her eyes were slightly red.

"Si'er, I'll be the first!"

Zuo pianfan's soft voice rang behind him. Yao Sisi nodded gratefully, looked down contemptuously, and then deliberately raised his voice and said, "my husband, come here."

The reason why she said this, first, showed Zuo pianfan's identity, and second, she thought it was useful to do so. How to say that a wife would not hurt her husband.

The army reacted, threw it over and said, "girl, I believe you."

She saved his parents' lives. Even if it was a sea of swords and fires, he was fearless, not to mention for everyone's good.

Yao Sisi felt better, so he slowly said, "the pus of the acne scab is not very toxic. If it is inoculated to healthy people, it can completely heal itself. Pre inoculation can make people have immunity to smallpox first."

Yao Sisi immediately bypassed the army and left pianfan, rolled up his sleeves and exposed his tender arms.

"Hiss..." there was a puffing sound below. Zuo pianfan's face was a little black. He wanted to go forward and pull Yao Sisi away, but he heard Yao Sisi whisper: "don't be jealous, I'm sure."

Sigh in your heart about the old society. Is it so shocking to show your arms? She was very indifferent. In full view of the public, she took out a knife, gently scratched a small mark on the skin of her arm, took out a little yellowish pus from the acne scab of the cowpox patient, and calmly inoculated it on the scratched skin.

Then, Yao Sisi took a deep look at the army and took a seed for Zuo pianfan. He looked at the peasant woman and son at the door of the inner house behind him, "aunt, Xiao Zhangzi, come here."

The same flower opened her arm, took out a little yellowish pus from the acne scab of the cowpox patient, and calmly inoculated it on the scratched skin. After finishing this, Yao Sisi didn't look at the people at the bottom. She didn't love sticking people's cold ass. she found the consciousness of being angry and said with a harmless smile: "if you want to do it, you can wait to die if you don't want to. This method is very simple. Do it yourself!"

Ten days later, only one person died in this smallpox, but it was not the child who brought the plague, but a coward who refused to vaccinate smallpox for fear of death. It is precisely because of this that the villagers respect Yao Sisi very much and worship him like a God.

"Thank you, girl."

The army knelt on the ground.

"Well, get up. Why are you kneeling again?"

Yao Sisi thought, sure enough, the ancients liked kneeling very much. It seems that there is a market for inventing "kneeling easily" in the future!

"No, girl, let me kowtow to you. If it weren't for you, it would be difficult for all the villagers to live, and my parents would burn alive. The girl and the childe will leave tomorrow. I told my parents that the army is willing to be a cow and a horse for the girl and the childe to repay the girl and the childe for their kindness."

"Do you want me to be short-lived? Get up."

Yao Sisi stepped forward to pick up the army and was about to say it again, but he heard Zuo pianfan's words that he couldn't hear his feelings.

"We don't need slaves."

Yao Sisi nodded approvingly, but she still enjoyed looking at Zuo pianfan's jealous face.

The army was a little distracted and was about to say something. Zuo pianfan had pulled Yao Sisi out of the door.

"Si'er, now that you have cured smallpox, I'm afraid it has been spread. I can't stay here. I always feel uneasy. Shall we go this afternoon?"

"Ice, why are you getting timid? Let's go back."

Yao Sisi hooked Zuo pianfan's arm and pulled her back.

Zuo pianfan looked at Yao Sisi suspiciously, "we just came out!"

"Didn't you say to leave in the afternoon? Let's not pack up!"

Yao Sisi jokingly ordered the back of Zuo pianfan's hand. He exerted more strength and dragged Zuo pianfan away. Zuo pianfan tried his best to hold Yao Sisi in his arms. The heavy man's breath filled Yao Sisi's neck. A low and soft voice said, "I've packed up. Don't go back. Let's go."
