Before time travel, Yang Fan was an office worker who got up early every day and worked late at night. He was a loser who could not afford to buy a house after working all his life.
During a business trip, he had an accident on a plane and his soul traveled to the Tang Dynasty.
After arriving here, he was tired of the fast-paced modern life and did not study hard to obtain fame, nor did he want to compete for world domination like other time-travelers.
After all, in his opinion, there is really nothing good about being an emperor.
In addition to having endless things to do every day, you also have to be wary of being assassinated all the time, and the food you eat is cold. What's the point of living like this?
After selling the Buddha statue and getting a hundred taels of gold, I bought two little girls as maids in the market, and exchanged the gold for some building materials and daily necessities.
He enjoyed the decadent aristocratic life of feudal society in Baishui Village, and stayed there for more than three months.
After all, in the Tang Dynasty, where the common currency was copper coins, brocade, silk and grain, the value of a hundred taels of gold (approximately 1,000 copper coins) was more impressive than the multi-millionaires before time travel.
You know, it only cost about twenty copper coins to buy two little maids.
If most of the gold hadn't been exchanged with the system for repairing the villa's building materials and some daily utensils, it could be said that he would have become a wealthy landlord long ago.
…
"Lao Fang, how did you know I live here and what do you want from me? Do you want to buy something again? I have a lot of good things here..."
After sitting down, Yang Fan asked.
After the renovation of the villa was completed, the money was almost used up, and I was looking for a boy to give money to. At this time, my face was full of expectations.
After all, he has been coveting the martial arts secrets in the system for a long time. As a man, who can not have a martial arts dream?
It was just the price of gold required to purchase martial arts secrets that stopped him.
Now that the villa is gradually getting on the right track, it's time to find a way to find money.
Fang Xuanling smiled awkwardly, waved her hands, and quickly told the reason.
"I didn't expect that my little brother is actually a baron from Wannian County, which makes you laugh. I just heard that there is someone in Baishui Village who can cure the smallpox plague, so I came to visit. I didn't expect that it was you, baron."
Fang Xuanling also felt guilty. After all, the last time he bought a Buddha statue, he spent most of his life's private money.
If the old mother had not believed in Buddhism all her life and it was her eightieth birthday, he would have been reluctant to buy it.
Li Shimin on the side looked at Yang Fan's young face, his eyes filled with disappointment.
He didn't think the young people in front of him could cure the smallpox plague.
Of course, Yang Fan wouldn't care so much, he waved his hand and said:
"Don't worry about whether you are a noble or not. As for the smallpox plague, you are not an official. What should you worry about..."
Smallpox will be dealt with by the court. Now that the plague is rampant outside, you still dare to run around. You are really brave.
"Although I don't have an official position, someone in my family is an official in the court, so I came to inquire about the situation. I passed by this place and heard that there are methods to prevent and control the plague, so I came to ask for advice."
Only then did Yang Fan suddenly realize, he sighed and said casually:
"Lao Fang, I disappoint you. I can't cure smallpox. I just know how to prevent smallpox infection."
"What did you say? You really know how to prevent smallpox."
Before Fang Xuanling could say anything, Li Shimin stood up excitedly, his eyes burning, and even the short beard on his chin began to tremble.
Fang Xuanling also stared at Yang Fan fiercely, obviously shocked by these careless words.
Nowadays, all the villages near the outskirts of Wannian County are empty. The smallpox plague has spread, killing and injuring as many people as crucian carp crossing the river.
Because so many people died, malaria also increased, making the plague more difficult to control.
Even Sun Simiao and Taiyuan Hospital were helpless against this plague.
How could they not be excited when they heard that the young people in front of them casually said that smallpox could be prevented.
As the rulers of the current dynasty, they have gone through ups and downs and have long been indifferent to life and death.
Their focus was not on those infected with the smallpox plague, but on those who had not yet been infected with smallpox.
As long as the number of people infected with smallpox does not increase, they believe that with the medical skills of Sun Simiao and Taiyuan Hospital, the smallpox plague will be controlled quickly.
Precisely because people were afraid of contracting smallpox, countless shops in the east and west cities of Chang'an were closed.
People also began to flee privately, and many people became refugees.
Even though the imperial court sent people to persuade people with good words, it still could not curb the people's fear of smallpox.
After all, if they continued to stay, their lives would be in danger, so the people wanted to escape from this place of right and wrong.
But once people move around, smallpox will spread faster and become more serious.
Therefore, when they heard that Yang Fan could prevent smallpox, they had no other words to express except that they were shocked.
Seeing the startled Li Shimin, Yang Fan glanced at him without replying, but looked at Fang Xuanling.
It seems to be asking - who is this person?
Only then did Fang Xuanling react and apologized.
"This is Li Shi, a member of the royal family. You can just call him Lao Li..."
A trace of surprise flashed through his eyes. Yang Fan did not expect that this middle-aged man with thick eyebrows and big eyes had some background.
After all, the idea of a seventh-rank official in front of the prime minister's door was not nonsense in feudal society.
Members of the royal family are even more superior to others, and crimes committed are not punished by ordinary laws, but are dealt with first by the clan government formed within the royal family.
However, he quickly calmed down after receiving modern education since childhood.
In his opinion, whether the royal family or the emperor, they are all human beings, that's all. After all, he is a cheating person.
Moreover, he also has a title. Although he is only the lowest baron, he still belongs to the ranks of the nobility.
Yang Fan's calm performance made Li Shimin and Fang Xuanling secretly nod their heads, secretly praising this guy for being extraordinary.
Even though they didn't tell their true identities, most people would be frightened when they heard about their fabricated identities.
Yang Fan doesn't care how rich their inner drama is.
"There is a way, but I'm afraid you won't dare to do it..."
Although Yang Fan's unhurried attitude seemed a bit rude, Li Shimin and the others didn't mind, and instead became even more excited.
Is this true?
But don't try to trick us, this involves tens of millions of people.
As long as the method is feasible, there is nothing in this world that we dare not do.
If the method works, I will go to the imperial court to ask for credit for you.
Seeing Lao Li's awesome look, Yang Fan held back his words. Yang Fan was a little scornful and didn't reply. He just looked at them and smiled.
To prevent smallpox, you must be vaccinated against cowpox, but not everyone dares to do this.
After all, cowpox is an antibody produced by cows infected with bovine smallpox.
Some time ago, I found cows with cowpox and asked the households in Baishui Village to vaccinate them with cowpox. However, they thought that they were seeking money and murder, and they almost started a riot.
If the smallpox epidemic hadn't been particularly severe later, and on the other hand, they were tempted by the promise of huge profits from tax exemption for three years, the households in Baishui Village would not have been willing to vaccinate against cowpox!
Even so, at first it was only a few elderly people who experimented.
Only after observing that there are no problems will others be willing to vaccinate.
This is understandable, after all, not everyone can accept unknown things immediately!
Even in the world before time travel, it was discovered that cowpox could prevent smallpox, but it took nearly a hundred years before universal vaccination began, and it was only implemented under the tough measures of great men.
So now when he saw Lao Li and Lao Fang's awesome guarantee, Yang Fan just laughed.
****
He took Li Shimin directly to a cowshed in the manor.
There were several cows lying in the cowshed, and there were a few scarred sores around the milk.
Li Shimin and the others looked horrified when they saw this.
"Why is this cow infected with smallpox?"
At the same time as he said this, Fang Xuanling pulled Li Shimin back again and again.
After the two ran away, they suddenly discovered that Yang Fan was looking at them jokingly with his hands folded.
Li Shimin suddenly turned pale and was frightened. He pointed at Yang Fan and cursed angrily:
"What do you want, kid? Do you want to cause us to contract smallpox?"
He pursed his lips, knowing that this would happen. He asked you not to show off your awesomeness just now, but now he is not scared to death, so he opened his mouth to explain:
"These cattle are indeed suffering from smallpox, but the symptoms of smallpox in cattle are much milder than that in humans, and the immunity of cattle is much stronger than that of humans. Therefore, after the cattle have developed their own resistance and immunity, they have developed a certain degree of immunity.
Therefore, smallpox is a fatal disease for humans, but it is rare for cattle to die."
Li Shimin and Li Shimin were stunned for a moment, feeling unbelievable.
It took a long time to react, but I still didn't understand, so I asked hesitantly.
"Is this how you control the plague?"
Not bothering to show off too much, Yang Fan continued:
"After the cow recovers from smallpox, it will form scars. I call it cowpox. This is the result of the cow's immune system producing antibodies against the virus. As long as cowpox is taken and inoculated into a human body, it will contain antibodies against the smallpox virus, stimulating
The human immune system can prevent smallpox."
After finishing speaking, he said to the two of them: "Lao Li, Lao Fang, who of you two will come first?"
The two of them swallowed their water and looked ugly.
"What do you mean?"
Yang Fan spread his hands and smiled slyly.
"Don't you understand? Now take out the cowpox and inoculate it on your arms. This way you will be able to resist smallpox."
The faces of Li Shimin and Li Shimin became darker and darker, and they waved their hands repeatedly.
"You... don't mess around..." Even his voice was trembling.
Fang Xuanling was also deeply afraid that something might happen to Li Shimin, so he hurriedly ordered He Dao.
"Yes, little brother, please stop making trouble... or we can find a few people to try first."
Seeing their fear of death, Yang Fan didn't laugh at them, but just said angrily.
"Whatever you guys...who was not afraid of anything just now?"
Li Shimin and the other two could only smile awkwardly.
Seeing their appearance, Yang Fan did not force himself, and then reminded them.
"According to the method I told you, within two to three days, some individuals will have fever, dizziness, red spots on the body and other immune reactions. The symptoms are very mild and not fatal. No medication is needed. As long as the symptoms subside, this person will be fine for the rest of his life.
Never get smallpox again."
Fang Xuanling and Fang Xuanling were hesitant, but they kept the steps and methods in mind.
