That's a hundred taels of silver, and with these hundred taels of silver, they just enjoy the blessings, and they take out the land, or take it out and put the money, and sit at home and just collect the money.

They have lived so long, and they have never seen how much a hundred taels is!

The expressions of the two were a little excited, and a little nervous, staring at Bingyan tightly, as if they were thinking about how much credibility Bingyan's words had.

As soon as Bingyan waved his hand, Meishuang immediately turned around and left, not to come out with a burden, and after standing up and opening it, the white and shiny silver ingots inside, they gasped when they saw it, it turned out to be real!

Reaching out and wanting to take it, Meishuang stopped it, and the two of them were stunned, a little embarrassed, a little scared, and couldn't help but look at the bag.

The man was a little bold, looking at the silver, looking at his wife, and finally raised his eyes slightly to look at Bingyan and said, "You...... What do you want us to do, this nobleman? We are all poor people, we have nothing to do, we don't dare to do illegal things, there are eighty high halls on the villain, and there are babies who can just speak, don't dare to do bad things......"

The woman was also stunned, and hurriedly nodded: "Yes, yes, no matter how much money you have, you can't do anything illegal, although we are just a small people, we also know what we can and can't do, and we definitely don't do bad things!" The woman waved her hand.

Bingyan looked at this pair of honest and simple people, and smiled: "Don't worry, I won't do bad things, and I won't let you do bad things, I asked you to come today to ask you to help save people, and the one hundred taels is your thank you." ”

"Saving people? What can we do? The woman was puzzled and looked at her husband, who also looked puzzled.

Bingyan was just about to speak, but suddenly closed his mouth again and said, "This woman usually comes into contact with cows, just now I saw the pox on your arm, this is what I need." ”

"This?" The woman's puzzled words?

Bingyan nodded, and the woman was even more strange: "Just this thing is worth a hundred taels?" ”

"That's right!"

The couple immediately looked at Bingyan with idiot eyes, a hundred taels of silver, just buy the pox on her body, is this rich person have too much money, I really don't know how to spend it, isn't this a disease.

Who doesn't have a bag on him, this thing is worth a hundred taels, the world is crazy, or this beauty in front of him who looks like a fairy, in fact, his brain is not normal.

Bingyan said this, not to mention the two of them, even the maidservants behind Bingyan were puzzled.

Although Bingyan is easy to speak, her means are quite powerful, although she is very generous to her subordinates and cares very well, but she never wastes silver, and she buys a few pox on a peasant woman for a hundred taels, isn't it a big joke?!

It's just Bingyan's face, but she is very serious, and no one dares to think that she is joking.

Everyone stopped talking, and Bingyan said, "I need it now, can you cooperate." ”

"Huh? Oh! You really give me a hundred taels! The woman saw that Bingyan was not joking, and asked again, Bingyan nodded, and the woman immediately laughed: "Okay, okay, you can give it to you if you need it, it's okay, it's okay, I agree, what's not to agree with!" ”

Bingyan's eyes blinked slightly, and he said to Meishuang: "Meishuang, you go and prepare, I want this lady to take the pox liquid, and let people prepare it now." ”

"Yes, Princess." Mei Shuang immediately replied, as for Bingyan, no matter how many doubts she has, she will definitely complete it 100%.

"What? Princess! However, when the couple heard Mei Shuang's words, they were almost frightened, and the one in front of them turned out to be a princess, which ...... This is the biggest official they have ever seen since they were born, eh, the princess doesn't seem to be an official, and it's not right, I heard that there is something wrong with that? The courtiers were about to kneel when they saw it, and the two of them immediately stood there, feeling uncomfortable all over.

Bingyan's mind was not on them at this time, and he took a deep breath.

In fact, the method that Bingyan thought of was also a method he knew in his previous life, in the modern smallpox virus or something, children will be vaccinated regularly when they are young, and few people have it, and many people don't know much.

Bingyan was also a medical project to be discussed, so he made up some knowledge, including mentioning this, at that time, Bingyan was only curious about smallpox, which had a high risk mortality rate in ancient times, so he popularized science for himself.

The infection rate of smallpox is high, the mortality rate is high, it is too difficult to survive by one's own willpower, the elderly and children who are weak are more likely to die, and the survival rate of adults will be higher if they are in good health.

But later, after research and overcoming, a way to resist smallpox was also found, that is, to plant cowpox.

Cowpox is an infectious disease in cattle, and it is generally easiest to get it by people who often deal with cattle, and the method is to integrate cowpox into the human body to make the human body immune to smallpox, so as to counteract the method of cure.

There are three methods of pox, liquid vaccinia vaccines, freeze-dried vaccinia seedlings and chicken embryo tissue vaccinia vaccines, the latter one, as soon as you hear it, is the academic name, in the current environment at all, you don't want to think about it, and the three effects are very good, now the most suitable is the first liquid vaccinia vaccine, to put it bluntly, it is the pox liquid that is transmitted to the human body.

Smallpox generally has an incubation period, so vaccinia vaccination is given on the second day after contact with the patient, smallpox may not occur, vaccination after 3 to 7 days can often prevent the disease, vaccination after 8 to 10 days can reduce symptoms, and vaccination after 10 days is ineffective.

If the vaccinated person has no immunity, there will be a primary reaction after vaccination: red papules appear locally about three days after vaccination, papules form herpes around five days, turn into pustules around eight days, form brown scabs around the twelfth day, and fall off after the eighteenth day, leaving scars. This is a sign of pox success.

Generally, pimples appear two days after the first pox after vaccination, and the herpes reaches its peak in four to six days, with fast scab formation and small scab cover, which is also the table of successful inoculation.

Although Bingyan still remembers the number of these professions and some processes, she must not have used them herself, as well as some possible sequelae, etc., plus Tuan Tuan's young age and fear of resistance problems, this pox is far from being as simple as she imagined.

But because Tuan Tuan and Dumpling Dance are not obvious now, I am afraid that in order to speed up the spread of the smallpox virus, something was added, so that their symptoms were faster, but now the situation seems that there are no two on Tilt Dance, and there are more Tuan Tuan, but it has not spread to the face and other eye-catching, and now the vaccination is likely to directly resist and not cause smallpox, and the ice smoke must be tried!

Now is the time to rush for time, I can't wait!
