Saving the people of Tang Dynasty is saving your own compatriots.

It doesn't matter if it's recorded in the annals of history.

Because he is not from the Tang Dynasty to begin with, he is just doing what he can do!

…

In the blink of an eye, three days passed again.

During these three days, Li Shimin and others were also observing the spread of the plague in the palace.

However, within three days, the disease suddenly broke out and more than 20 people were infected with the plague.

But what makes Li Shimin happy is that he is not infected, and no one who has been vaccinated is infected.

In this way, Li Chengfeng's vaccine is really effective.

Because those ministers all went to Li Chengfeng's Prince's Mansion to get an injection.

It can be said that Li Chengfeng directly gave them a gold medal to avoid death in the era of plague!

One word, strong!

Two words, very strong!

Three words, super strong!

Four words, Ju Ni Ma is strong!

It is no exaggeration to say that the vaccine developed by Li Chengfeng is a fairy medicine from heaven.

Therefore, many ministers couldn't help but place their hopes on Li Chengfeng.

Not only that, Li Chengfeng is now also training ten imperial doctors in the Zhenwang Mansion and teaching them how to give people injections.

The place where the injection is given can be the arm or buttocks.

The needle needs to be prepared quickly and inserted into the blood vessel.

Don't dawdle or dare to plunge in.

If it doesn't penetrate the blood vessel, you will have to re-inject it.

Therefore, in order to train them how to vaccinate, Li Chengfeng asked them to vaccinate each other.

Those imperial doctors were miserable.

Because I don’t know how to hit, you hit me and I’ll hit you.

Ten people were holding needles and pricking them back and forth.

There were more than a dozen needle holes pierced in the arms, and finally they were pierced in the buttocks.

Although the process was painful, it was also a bit funny.

But eventually, they learned how to inject and vaccinate people.

This is a long process.

But as long as he teaches them, Li Chengfeng will only need to provide medicinal materials in the future.

He doesn't have to inject everyone one by one to prevent the plague.

Otherwise, Li Chengfeng will die from exhaustion.

The entire city of Chang'an has a population of more than 5 million.

Even if an average of a thousand people are injected every day, the power of one person will take 5,000 days, the power of ten people will take 500 days, and the power of 100 people will only take 50 days.

Therefore, after Li Chengfeng taught them how to give injections, he also asked them to teach them to others.

As for the medicinal materials, just provide them yourself.

Although, this is a huge expenditure!

A vaccine has ten naughty points, plus needles, syringes and other medical equipment, a set will give you about 30 naughty points!

If Li Chengfeng really wants to save the people of Chang'an City, he needs at least 10 million naughty points!

However, there are currently only 1 million naughty points in his system!

This can't help but put Li Chengfeng into trouble!

However, at this moment, the system sound suddenly sounded.

"Ding, the benevolence of the host's doctor has been detected, and the host is specially rewarded. Any medical equipment can be used for free! The usage rights are permanent!"

"Damn it, system, you have a conscience! I thought you had no conscience!"

Li Chengfeng laughed happily.

Maybe the system also feels that if it doesn't work hard, it will be difficult for Li Chengfeng to solve it alone.

So the system simply provided Li Chengfeng with all the medical equipment without any permission to use it.

Not only that, from now on, as long as the system is on Li Chengfeng, Li Chengfeng will have the right to use medical equipment for free forever!

"Okay, good, system, you did a very good job this time!"

"Thank you host for the compliment! That's because I detected the host's kindness as a healer, and the system feels that the system can help the host complete this task!"

"Okay, thank you very much! I will earn you more naughty points in the future, is that okay?"

"Okay, thank you host!"

The system also has intelligence, but it does not have human emotions.

It's just a cold mechanical sound!

It has its own thoughts and can also talk to Li Chengfeng.

With the help of the system, all difficult and complicated diseases will be solved!

…

With the help of the system, Li Chengfeng prepared enough vaccines and gave them to the imperial doctors in the palace to vaccinate everyone in the palace, commonly known as injections.

Moreover, those who were originally ill, with the help of Li Chengfeng, were cured of their illness and regained their vitality.

This made everyone feel that Li Chengfeng was simply a god sent from heaven to save the Tang Dynasty!

Whether it is a natural or man-made disaster or a rampant plague, the Eighth Prince has a way to solve it and save the people of the Tang Dynasty from dire straits.

Therefore, Li Chengfeng has reached an unprecedented height in the minds of the officials of the Tang Dynasty.

Including Li Shimin himself, he also respects and admires Li Chengfeng very much!

If it weren't for Li Chengfeng, he would have died countless times.

However, Li Chengfeng had no intention of missing the palace.

Because he knew that he still had some friends who stayed in the private city of Chang'an.

Therefore, before the plague breaks out, Li Chengfeng must give Fan Meng and others a shot of vaccine.

Take protective measures for them!

Just do it.

Li Chengfeng then gave Eunuch Wu instructions and went out on his own!

…

Riding a red-maned horse, he arrived at the attic of the east wing of Chang'an City.

Along the way, Li Chengfeng saw that people were still coming and going on the street, which was very lively.

Moreover, they seemed to have no attitude or measures to prevent the plague.

This is a bad habit, and it is very likely that the plague will accumulate and break out in a certain period of time!

After arriving at the East Wing Pavilion.

Li Chengfeng saw that there were people eating lunch inside?

The pub is still open.

There was an endless stream of pedestrians inside, and Lingzi, Uncle Ta and others were also serving tea, water and food to the customers.

When did this happen?

Why don't you close your shop? Is it worth contracting the plague for such a small amount of money?

"Lingzi, Uncle Tazi! Why are you still in business? Where is the boss lady?"

Li Chengfeng walked in and called their names familiarly!

Lingzi looked at Li Chengfeng, her face lit up, and she said with a smile: "Eighth Prince, you are finally here. I haven't seen you for a long time!"

"Did you miss me, little girl?"

This little girl has been developing very well recently!

Although she is only 13 years old, she is already a slim and elegant girl.

Uncle Tazi wiped the sweat from his forehead and said: "Eighth Prince, you are finally here! Come, sit inside and I will cook you a duck to eat!"

Li Chengfeng waved his hand and said: "No, Uncle Tazi, I'm not here to eat, but to see Boss Fan Meng to warn you about a serious problem!"

"Serious problem? I know, isn't it the plague that's been raging recently? Oh, don't worry, it's a blessing, not a curse, we can't avoid it! We will be fine!"

Uncle Tazi seems not to be afraid of the plague at all.
