Datang: The prince of salted fish was overheard by Li Er

Although he was a little speechless about Li Shimin's expression just now, Li You still said: "Father, this medical laboratory mainly researches some breakthrough medical topics."

"For example, what we are studying now is the improvement of the smallpox vaccine!"

Li Shimin was shocked again, and immediately remembered the purpose of his visit this time.

"You'er, smallpox is a terminal illness. I heard that you passed a smallpox village on the way back to Beijing. Are you okay?"

These words came from the heart, and Li You naturally felt it immediately.

He rolled up his sleeves, revealing a scabbed scar on his arm, and said, "Go back to Father, I'm fine now."

"I vaccinated myself with cowpox, and I will never get smallpox again!"

Li Shimin was very puzzled. Although he knew that people who had had smallpox would not be infected again, what was this cowpox, and what did they mean by the vaccine just now?

It took Li You half an hour to explain to Li Shimin exactly what happened.

After fully understanding, Li Shimin took a breath.

"You'er, according to what you said, Datang won't worry about smallpox anymore?"

Li You nodded and said, "That's the case in theory, but it will take some time to vaccinate all the staff, and the first-generation vaccinia virus is still a bit violent."

"When I vaccinated Shence Wei before, some people had very severe adverse reactions."

"However, after observing this period of time, I am sure that cowpox will not easily spread from person to person."

"I think there will be a vaccine with a milder response soon."

Li Shimin was astonished at this moment, he asked curiously: "Your, since smallpox can be vaccinated, what about other plagues?"

[Mingjun is Mingjun, you think very quickly, and you can draw inferences immediately. 】

[However, plague is actually just a general term, referring to vicious infectious diseases, such as plague, smallpox, influenza, cholera, and malaria, which may cause plague. 】

[Some of these diseases have specific medicines, some can only be prevented by specific vaccines, and some have no way at all. 】

[It is difficult to completely eradicate the plague. 】

Li You suddenly remembered the flu epidemics that spread around the world in his previous life, and felt inexplicably heavy in his heart.

Seeing Li You's sudden silence, Li Shimin also realized the seriousness of the problem.

Now that Li You has managed to develop the real smallpox vaccine, it is really difficult for him to solve all the problems.

Li Shimin immediately felt that his nose was a little sore, and he quickly changed the subject and said, "It is the Tang Dynasty's fortune that You'er can develop the smallpox vaccine. We will not be afraid of him for other plagues."

This time Li You also nodded: "Yes, man will conquer nature, we will not be afraid of him."

[China has experienced 5000 years of plague, has it experienced fewer plagues? 】

[May I ask which plague in history really destroyed the children of China? 】

[No, not once. 】

[From ancient times to the present, whether it is the ancient times when medical conditions were scarce, or the modern times where science and technology continue to develop. 】

[In the face of the epidemic, there will always be countless medical workers who dare to go against the trend, relying on unremitting efforts to complete miracles of life one after another. 】

[Although history is moving forward and dynasties are changing, this belief will never be shaken. 】

[The epidemic cannot destroy Chinese civilization, even if it bends his back. 】

Li Shimin's words aroused the pride in Li You's heart, as well as the stubbornness of the former doctor.

He looked into Li Shimin's concerned eyes and said: "Father, please rest assured, with my son and minister here, I will definitely control the epidemic in Datang to a minimum."

"The plague can't stop Datang from becoming stronger."

Li You's words in turn aroused Li Shimin's pride and yearning for a prosperous Tang Dynasty in the future.

On this day, the father and son had a lot of heart-to-heart talks, until the eldest grandson Wuji and Fang Du arrived.

The three of them came to report the disaster.

As early as the first day of cooling down, Li Shimin asked the three of them to pay close attention to the situation in the cooling area.

After a few days, they finally received reports from various places.

Knowing that the emperor cared about this matter, they naturally didn't dare to neglect and sent it over immediately.

"Three prime ministers, how is the situation?"

Li Shimin knew the purpose of the three of them, so he asked.

Changsun Wuji said happily, "Congratulations, Your Majesty, it's all good news."

It turned out that during this period of time, the Ministry of Industry, the Ministry of Household Affairs, and the Si Nong Temple had already made complete preparations, not only reinforcing some houses, but also distributing a lot of coal.

After the temperature dropped, not only the people were not affected, but even the crops in the land were protected from frost loss because of the charcoal fire.

Although the autumn harvest has been completed at this time, the new crops promoted by Li You have only just been planted.

Li You's idea is to leave more food for the people before winter comes.

Hearing the report, Li Shimin was also overjoyed.

Then he looked back at Li You, he knew that such a result was due to Li You.

He chuckled and said, "You'er, you are in charge of this household department. Duan Lunzhen of the Ministry of Industry knows that he has a good relationship with you, but why does Sinong Temple listen to you?"

Li You respectfully said: "Your Majesty, the purpose of fighting against natural disasters this time is to relieve the common people. Secretary Dou Jing of Sinong Temple has always cared about the suffering of the common people. After receiving the letter from the Ministry of Household Affairs, she naturally strongly supported it."

"It's also thanks to Si Nong Dou that things went so smoothly this time."

【Hey, who is Dou Jing? That's the funny second brother. 】

[Don't say that he is concerned about the food issue, even if he doesn't care about it, if he is a joke, he still has to help his younger brother. 】

[Blood is thicker than water, understand! 】

Hearing Li You's bright and dark answer, Li Shimin finally understood.

In any case, this possible natural disaster disappeared invisible in the hearts of the three people and officials at all levels.

Li Shimin was in a good mood: "Very good, you all did a good job this time. I will reward you all!"

"You'er, whatever reward you want, just ask, and I will give it to you!"

In fact, Li Shimin had long wanted to reward Li You.

He got too much from Li You.

But either the information came from Li You's inner voice, and even if he wanted the reward, he was an unknown teacher, or Li You was too salty and didn't even bother with his own reward.

And this time, it is an excellent opportunity.

Li Shimin believed that after the conversation between the father and son just now, Li You's temperament should be restrained.

Hearing that Li Shimin wanted to reward him, Li You was also taken aback.

If Li Shimin had asked him this way before, Li You would definitely have had some shocking complaints in his heart.

But today, when Li You was asked by Li Shimin, he really wanted something.

Li You cupped his hands and said, "Thank you for your majesty's reward. You'er really has a request, but I don't know if your majesty is reluctant to part with it."
