Imperial Physician Chen was a little frightened, but more surprised.

He had practiced medicine for many years, and he had seen the severity of smallpox and witnessed the loss of life due to smallpox.

As a young man, he himself contracted smallpox, but the symptoms were relatively mild and he survived.

After he recovered, he also had a little pockmark left on his face.

Now that I'm older, on that loose face, the pockmarks left over from smallpox and age spots are mixed together, and I can't tell them apart.

The old lady's surprise was also expected by Zhu Ying.

After all, it is still the Hongwu period, and it is normal for them not to understand the "human pox inoculation method".

Lao Zhu asked curiously:

"What is the "human pox inoculation method"? Doctor Chen, do you know? ”

Imperial Physician Chen eased his nerves.

"This method of preventing smallpox has been heard of by the minister, but the minister has never used it.

In short, it is to let smallpox patients with mild symptoms infect normal people, and let normal people also become smallpox patients with mild symptoms. When he recovered, he would no longer be infected with smallpox, so that his life would be saved. ”

After Lao Zhu heard this, he thought it was ridiculous.

"Which evil doctor came up with such a vicious solution? Isn't that nonsense! How could a good person be deliberately infected with that evil smallpox?! ”

The ancients said: "The body is skinned, and the parents who receive it dare not destroy it, and the beginning of filial piety is also."

Allowing a normal person to deliberately contract smallpox and disfigure, morally speaking, is an act of unfilial piety.

However, there are a very small number of people who can't take care of so much in order to survive.

After all, the mortality rate from smallpox is so high that mild symptoms have a much better chance of survival.

The more ignorant they showed, the more excited Zhu Ying became.

When he relies on his own cognition to solve the problem of smallpox, then Lao Zhu will definitely be impressed by him.

Zhu Ying asked unhurriedly:

"Doctor Chen, do you think that if this "human pox vaccination method" can be popularized throughout the country, will more people survive? ”

Imperial Physician Chen stroked his white beard and thought about it carefully.

"Well, theoretically, yes!"

Zhu Ying smiled and looked at Lao Zhu.

"Grandpa, the more people survive, the more the population will be. When the population increases, productivity increases, arable land increases, food increases, and the combat effectiveness of the army becomes stronger! Does what I mean by making sense? ”

"This ......"

Lao Zhu was speechless for a while.

After thinking for a moment, he suddenly said:

"Then in this way, won't the people of our Ming Dynasty become ugly pockmarked faces in the future?!"

Imperial Physician Chen hurriedly catered to him:

"What Your Majesty said is very true!"

Zhu Ying's face did not change, and then he asked:

"Doctor Chen, what do you think would be the effect if the cowpox virus was used on people to deal with the smallpox virus?"

Hearing this, Imperial Physician Chen's mentality also exploded!

"The meaning of the emperor's eldest grandson is to let cows with cowpox infect normal people?!!"

Zhu Ying was very happy that the old lady doctor finally got her senses.

"Exactly! This is the "cowpox inoculation method"! ”

Lao Zhu stood up again to refute.

"Ying'er! The more you talk, the more unpleasant it becomes! ”

"Grandpa, don't worry, listen to me carefully!"

After calming Lao Zhu's emotions, Zhu Ying began to explain seriously.

"The smallpox virus is a double-stranded DNA virus, which makes it almost impossible for it to mutate.

Although vaccinia and smallpox are two completely different diseases, their pathogens, vaccinia virus and smallpox virus, share cross-reactive antigens, which is why humans are immune to smallpox by vaccinia.

Cowpox, on the other hand, is almost harmless to the human body and only leaves a slight scar at the place where it was inoculated.

Therefore, even if people are vaccinated with cowpox, they will not become "pockmarked faces"!

Once all human beings are immune to it, smallpox will have no place to live and will only go extinct! ”

After hearing Zhu Ying's words, Lao Zhu and Imperial Physician Chen were stunned.

They are like listening to a book from heaven, and they don't understand it at all.

Zhu Ying explained:

To put it simply, it is what we call "fighting poison with poison" in traditional Chinese medicine, using vaccinia virus to attack smallpox virus! ”

Imperial Physician Chen suddenly realized this, and couldn't help but exclaim:

"Your Majesty! What an amazing idea of the emperor's eldest grandson! Lao Chen has devoted himself to studying medical skills for many years, and he has lived more than seventy years in vain! Why didn't you think to give it a try with this method? ”

"Imperial Physician Chen doesn't have to be modest, I just happened to learn about this method."

Lao Zhu looked puzzled and hurriedly asked:

"Imperial Physician Chen, what do you mean by that?"

Doctor Chen explained seriously:

"Your Majesty!" Fighting poison with poison" has had miraculous effects since ancient times. Although cows have cowpox, they do not kill them, and it is difficult for people to survive smallpox.

The old minister thinks that the method that the emperor grandson just said can be tried! ”

Lao Zhu hesitated for a moment, and suddenly asked excitedly:

"Good grandson, are you really sure to solve the problem of smallpox?"

"Of course!"

Zhu Ying is full of confidence.

"And what are you going to do?"

Zhu Ying has thought about this question for a long time.

"I hope Grandpa can arrange for me to be fully responsible for this matter!"

"Who do you need? Be specific. ”

"I need Imperial Physician Chen to organize a medical team to assist me, and I also have to go to the Beijing prison to find 20 death row inmates for experiments.

In addition, I need a right-hand man to help me with some necessary tasks.

Of course, start-up capital is also needed. ”

Zhu Ying's words made the two people stunned.

Old Zhu stomped around and thought for a while.

"Imperial Doctor Chen, what do you think?"

Dr. Chen had never taken on such a challenge, and he had already contracted smallpox and would not be infected again.

If this technique works, maybe a miracle will happen, and he will become one of the heroes who defeated the smallpox virus, and his name will go down in history!

Such a rare opportunity, of course, he will not miss it.

It is a miracle that the emperor's eldest grandson, who had been in a coma for seven days and seven nights and had experienced many high fevers, could wake up.

Imperial Physician Chen hoped that he would have the opportunity to follow the emperor's eldest grandson to witness another miracle.

"Your Majesty! The old minister is willing to wait for the emperor's eldest grandson to send! ”

After thinking for a moment, Lao Zhu nodded.

Still, he has concerns.

The world is sinister, the capital is no better than the palace, and it is too dangerous to let the eight-year-old grandson go out rashly.

"Good grandson, grandpa will promise you this time. However, for your safety, I still have to plan in detail.

Grandpa has to find a safe place for you, and he has to send more people to protect you.

Moreover, this matter has to be discussed with your grandmother and your father. ”

Before surviving the death catastrophe (the first day of the fifth month), Zhu Ying did not want to act in a high-profile manner.

"Grandpa, this is a secret plan, the fewer people who know about it, the better. I don't want my grandma and dad to worry, and it's not too late for you to tell the world when the final results come out. ”

"Oh well! I'll arrange the right people for you, and I'll hand them over to you tomorrow! ”

You'll be able to get out of the palace cage in no time.

This time, being able to stay outside the palace for more than half a month, Zhu Ying is looking forward to it.
