If you can't make it, go back to school and get your meal card!

[Hmm? How can I hand over the method of preventing smallpox reasonably...]

[Like in the novel, find an ancient book... I wonder if it will work?]

[I...]

The old emperor: "Today's banquet ends here. Dou Qing, Qin Qing, and Xie Qing stay to entertain the guests. The rest of you can stay or leave if you want."

[Huh? It's going to end so soon?]

[Then can I go back and fake it now?]

[Wu Hu!]

[For things like this, the sooner the better. What if it's just half an hour!]

After the old emperor left, Xu Yanmiao bent over and carefully slipped away while everyone pretended not to see her.

[Tsk, as expected. Although the old emperor said that the party could be dispersed, many people did not move. Fortunately, I had already found a way to sneak away. 】

Ministers and Jinyiwei: We can't see it! We can't see it!

The next day, when Xu Shizhong was on duty in Wuying Palace, he presented an "old book" to Emperor Tiantong.

The emperor: "...You mean, you found an old book with a method to cure smallpox?"

Xu Yanmo was shocked: "Your Majesty! It's to prevent smallpox!"

Curing smallpox is too exaggerated, how could he have such ability!

The old emperor nodded, looked at the "old book", and his expression became subtle.

It was not him who said that Xiao Bai Ze's counterfeiting method was really terrible. It was so obvious that it was definitely artificial. It was not a little worse than what he did back then!

But...

the old emperor made a look of regret: "There is actually a method to prevent smallpox in the ancient books! I think too much of the essence of our Chinese people was lost in the war."

This was originally said casually.

Xu Yanmiao: [Who said it wasn't? In order to confuse the real with the fake, I also used the system to find a lot of past cases. I didn't expect that as early as three hundred years ago, someone had come up with a method for rare smallpox! There was even a cowpox method - although it was different from the cowpox method in the West. In short, such an important thing was not passed down! What a pity...]

War really destroyed civilization.

The old emperor was silent.

I don't know why, but my mood suddenly became a little heavy.

He picked up the ancient medical book that Xu Yanmiao had found, and read it carefully with an attitude of worshiping ancestors.

"Steaming rat meat, white buffalo lice, white pigeon meat, and centipede eggs can keep you from getting smallpox for life..."

"Seal a pair of white pigeon eggs in a bamboo tube, place them in the toilet and soak them in feces and urine for half a month, take them out, and mix egg white with three coins of cinnabar... You will never get smallpox, and even if you do, it will be rare."

"White philtrum can prevent smallpox..."

"Boil white pigeon feathers and bathe children to

relieve the symptoms of smallpox." "Boil rabbit heads and bathe

children to relieve the symptoms of smallpox." "Let children roll in pig nests to relieve the symptoms of smallpox."

"Use one white buffalo louse that has been infected with smallpox for one year, mix it with rice flour to make a cake, and eat it with children on an empty stomach to remove the foul feces. You can avoid smallpox for life."

"Dry seedling method...water seedling method...pox coat method...nose seedling method..."

There are hundreds of methods!

I wonder what kind of risks the ancient sage took to find a way to prevent smallpox when smallpox was prevalent.

Turning to the end, the old emperor saw the method added by Xu Yanmiao: cowpox method.

"...put the abscess of the cow into the human body through the wound...this method is safer than the human pox method, and the infection is milder..."

Xu Yanmiao noticed that the expression on the old emperor's face became particularly complicated, and couldn't help asking: "Your Majesty, but what's the problem?"

He was a little nervous.

Xu Yanmiao always knew that the world is not so black and white, and it doesn't mean that a useful thing will be promoted after it is taken out. Even if this thing can save lives. There

will be people who don't believe it can save lives.

There will be people who don't want this life-saving thing to be promoted because of their own interests.

Some people will refuse to accept new things just for the sake of stability.

Even if you present data - like when wheat was first promoted, the court told the world that the yield of wheat was twice as high as that of millet... Do you think farmers would be immediately grateful and eager to plant wheat?

No, the court promoted it for four years, but only allowed some areas to switch to wheat.

The emperor in power at that time was still a heroic ruler with great talent and strategy, and his posthumous title was "Wu". But even so, it took hundreds of years for all the people in the Central Plains to accept and plant wheat.

Xu Yanmiao couldn't imagine that the court's promotion was so slow. If the old emperor didn't believe in the cowpox method, how difficult it would be to spread this method.

It might even be lost!

——In fact, if Xu Yanmiao had understood the cowpox method well at the beginning, he would know that in history, this method disappeared twice after it was introduced to China.

The old emperor closed the book and was silent for a while, then said, "Putting cow abscesses into the human body through the wound, is this method..."

He paused and tried to be tactful: "Isn't it a little too magical? How can you put things from animals into the human body?"

The old emperor looked at Xu Yanmiao again and sighed: "I trust you very much, and I can even issue an edict to promote it. However, there will be many people who don't believe it. I was also a commoner, and they even said that if you get vaccinated with cowpox, cow horns will grow. It is very difficult to get people to be willing to get vaccinated with cowpox."

Especially... to put it bluntly, there is no smallpox now, and lives are not threatened. Who would be willing to try to put things from animals into the human body?

When the old emperor said this, Xu Yanmiao was stunned: "But when smallpox appears, those who get smallpox will surely die!"

Vaccination can only prevent smallpox, not cure it!

All Xu Yanmiao got was the old emperor's silence and sadness in his eyes.

"..."

Xu Yanmiao bowed and whispered: "I'll take my leave first."

The old emperor was a little at a loss: "You... There must be a way out when you reach the mountain. Don't think too much. I will issue an edict first, and let the officials promote the cowpox method in various parts of Daxia. It is still somewhat useful."

"Thank you, Your Majesty."

*

Xu Lang entered Wuying Hall happily, but when he came out, he lowered his eyes and pursed his lips, looking unhappy.

After hearing the news, the ministers were shocked and confused.

"What happened?"

Didn't he go to talk about smallpox? Why was Xu Yanmo so sad about such a good thing that would be passed down through the ages and save countless lives?

Some ministers selected several memorials and pretended to go to Wuying Hall to report on affairs. When they arrived there, they pretended to see the ancient book on smallpox and asked the old emperor to borrow it to take a look. After reading it, they immediately realized why Xiao Bai Ze was so sad.

"The cowpox method is indeed..."

Cui Yi, the deputy minister of the Ministry of Revenue, was unusually serious: "Your Majesty, I request that other methods be promoted first, and as for the cowpox method, you can proceed slowly."

Take it step by step, and first accept the relatively acceptable ones. For example, white (urine stains) in the human philtrum, white pigeon eggs, etc.

... Although urine stains may not be acceptable to many people ()

The old emperor nodded: "Let's do it this way for now."

Even if it is not as effective as the cowpox method, it can still save lives.

*

Half an hour later, the guards guarding the palace gate looked strange: "Xu Lang, what are you doing?"

Xu Yanmiao was sitting on a wooden cart pulled by horses, with boxes of things around him.

He jumped off the carriage: "You can check it out."

After the guards carefully searched the boxes, they let him go, but their expressions became even stranger.

Xu Yanmiao didn't pay any attention to this. He just sat back in the carriage and told the driver to go on.

- He was granted special permission by the emperor to drive in the palace.

When the carriage stopped in front of Wuying Hall, the old emperor was stunned: "What are you doing?"

Xu Yanmiao ordered the palace servants to help him move all the boxes in, and then said happily: "Your Majesty! I have come up with a good way to make people willing to get vaccinated... I mean, to get vaccinated against smallpox!"

The old emperor smiled: "Huh? What's the method!"

"Wow--"

Xu Yanmiao opened the box, and a box full of copper plates appeared in front of the old emperor. As Xu Lang opened the box, the copper plates fell to the ground with a clang.

The young man smiled and said, "Your Majesty! I have brought all the gifts from Your Majesty in the past, as well as the jewelry that the princess gave me before. There should be a lot of money."

The emperor was silent.

He looked at the young man and said without thinking, his black eyes shining: "If everyone who comes to get vaccinated can get a reward of 300 coins, many people will come!"

"I am willing to donate all my property except the house!"

Dimly, he seemed to be glowing.

But...

the old emperor thought sadly: "How many people can you save with this money?"

He thought so and asked so.

Then he heard Xu Lang's embarrassed voice: "I have spent too much money on food and clothing, and now I may only be able to vaccinate 10,000 or 20,000 people."

But he said happily: "If I can save one person, it's one person. I am not a savior. At least if smallpox breaks out now, these 20,000 people can survive well!"

As for the lack of money in the future and the bad life, the worst thing is to go back to the modern world.

He still has 200 yuan in his meal card!

*

The old emperor wanted to describe to Xu Yanmiao that if smallpox broke out now, at least 80% of the people in the world - except for those 20,000 people, would blame you for not forcing them to get vaccinated, and why they couldn't be one of the 20,000 people.

But when the words came to his lips, looking at those clear and brilliant eyes, he could only swallow them back.

"Enough!" The old emperor knocked on Xu Yanmiao's forehead. When Xu Yanmiao reflexively stepped back and covered his head, he seemed quite impatient: "Take all the money back. When will it be the turn of a young man like you to use the money you will use to marry a wife in the future to do things?"

Xu Yanmiao's eyes lit up: "Your Majesty?"

The old emperor knocked on his forehead again, but his tone softened unconsciously: "There is still a lot of money in the national treasury, and a lot of gold and silver have been mined from Japan, which is enough to attract the people to get vaccinated."

Xu Yanmiao was willing to take out all his belongings to promote this matter. This world belonged to his Gao family, and the dead people were all the people of his Gao family. If Gao Jianyi was reluctant to spend money, he would be worse than a beast.

After all, Japan has a lot of gold and silver. If they smash a gold mountain, it will not be enough to vaccinate all the people in the country.

This decision was welcomed by Xu Yanmiao's enthusiastic cheers: "Your Majesty is wise!!!"

The old emperor accepted it all: "I am indeed wise, if I am not, you should be dead now."

Xu Yanmiao's eyes widened.

The old emperor grabbed the kettle on the table and gulped down a few sips of water directly from the spout of the kettle. Then he said earnestly: "You spend all your wealth to help the people. You are buying the hearts of the people, do you know? If it were a suspicious emperor, he would not care about you..." He

would not care whether you died or not, and there would be no secrets in the world.

"He doesn't care whether you can prevent smallpox or not. For the sake of the dragon throne under his buttocks, he must kill you."

"But I..."

"I know you don't have this idea, but what about others?" The old emperor sighed: "Xu Yanmiao, I am not sure how many years I can live. I believe that the crown prince is not a tyrant, but you are still young, only 20 years old. It is not impossible to welcome the crown prince to succeed the throne. No one knows what kind of person the person on the dragon throne will be by then."

"Xu Yanmiao."

"You have to learn to protect yourself."
