Emperor Lan Chongdi's eyes were as calm as a pool of stagnant water, and he looked at Prince Gong's hairline steadily, and was silent for a while before he said, "What is the emperor's opinion?" ”

That's what I think I should do, so what do you think I should do?

You can't just guess and cure people for the crime of bullying the king.

"In my humble opinion...... can send him to the hardest-hit area of the epidemic, and see how he handles himself, if he is sick, the evidence is conclusive, and he should be beheaded, even if the royal brother is gracious, he will probably not survive. If he is fine, he can be ordered to free his hands and feet to cure the plague, and if he does not cure the plague well...... We can punish him for another crime of unfavorable governance......"

A trace of gloom flashed in Prince Gong's eyes, and his right hand slashed in front of his neck, and the killing intent was obvious.

Emperor Lan Chong was silent.

"In short, we can't let the prince of Yulan live, after all, it is about the face of my royal family, but if he is allowed to hide in the Yulan Palace, we can't move him, we can only let him leave the shelter of the Yulan Palace......"

There is no one else here, Prince Gong directly opened the skylight and said brightly, "Now no one in the DPRK dares to serve in the hard-hit areas of the epidemic, and it is justified for us to send him there...... I hope that the royal brother will decide. ”

Emperor Lan Chong's slender pale hand gently caressed his lips, and he muttered: "Brother Huang is reasonable, then, you can handle this matter." ”

Prince Gong bowed down and bowed: "Brother Minister, obey the order!" ”

Meanwhile.

Xu Tian, who was far away in Chixia County, was standing on the balcony, looking at the north.

There is the direction in which the imperial capital is located.

It's all here.

Presumably, Prince Gong and the Emperor have already discussed their strategies to deal with them.

"It's windy outside, and you've just recovered from the epidemic, so it's better to go into the house and rest more."

Just when Xu Tian was thinking about it, Xu Yuanhong's figure quietly came.

This prince, who has his son in mind, came to see him again after his official duties.

"Father." Xu Tian bowed.

"Hmm." Xu Yuanhong said, "What are you thinking?" ”

Xu Tian didn't want to hide it, and said, "Father, if the child's expectations are good, I will leave the palace soon." ”

Xu Yuanhong was stunned: "Why is this?" ”

Xu Tian said: "In the next few days, His Majesty's will to canonize the child is about to come down, and the official position of canonization will not be low. When the time comes, they will send me out to do great things. ”

Xu Yuanhong: "??? ”

Son, are your brains burned out?

You have no fame, no academics, and no combat power, and Your Majesty will come to canonize you for some reason?

What are you doing when you are canonized, what will you do?

The official position is not low, and he still does great things? Didn't you give up the throne to you?

Xu Tian was not without self-knowledge, knowing that his father didn't believe it, so he smiled and didn't say much, and changed the topic: "Don't talk about this first, father, you come with me." ”

"What's mysterious?"

Xu Yuanhong followed him into the back room, Xu Tian had already ordered someone to clean up the mess left by the previous experiment, and the bedroom was still the same as in the past.

"Please roll up your sleeves."

Xu Yuanhong rolled up his sleeves, revealing solid arms with well-defined muscles.

Then Xu Tian took out a syringe.

The kind of plastic syringe that is exactly the same as on Earth!

Plastic syringes.

This is the result of Xu Tian's experiments that have been locking himself in his room these days.

The needle is made of PP, which is polypropylene.

He first made propylene by petroleum cracking, then synthesized polypropylene through complex fusion, and finally made this non-toxic and odorless plastic needle tube with a mold.

Although plastic has not yet appeared in this world, it is not difficult for Xu Tian, a monk who studies monks, to synthesize plastics.

It can be said that he is the inventor of the plastic of this world.

"What is this?"

Xu Yuanhong couldn't help but ask.

Xu Tian didn't answer, but directly stabbed the needle into Xu Yuanhong's arm and pushed the cowpox vaccine inside.

The pain of the needle prick could be completely ignored by a forty-eighth-level powerhouse, but Xu Yuanhong still couldn't understand what his son was doing.

"This is a vaccine for the plague."

Xu Yuanhong has never heard of the term vaccine.

"After planting this vaccine, Father, you will have some symptoms of the plague, but it is very mild and never fatal, and when the symptoms are recovered, you will produce the virus in your body...... Antibodies to the plague will never be infected with the plague again in the future. ”

"Is there such a thing?" Xu Yuanhong was shocked.

"The child was vaccinated before, so that everyone mistakenly thought that he was infected with the epidemic, but in fact, the child was protecting himself and making himself permanently immune." Xu Tian took the trouble to explain.

"That's ...... so"

Xu Yuanhong looked at him incredulously, "How did you find this vaccine?" ”

And the name is also good, vaccine, catchy.

He found that he didn't know the son anymore.

Xu Tian had already thought about the background of vaccine research and development to fool others: "That's the case, the child heard that his father was worried about the plague that was gradually spreading in the neighboring county recently, so he wanted to find a way to prevent the plague for his father. ”

Xu Yuanhong nodded and listened attentively.

He had indeed heard from someone that Xu Tian had been to the pasture, and at that time he wondered how this son could go to that kind of place.

It turned out to be because of this.

"The smallpox symptoms on the ranch staff were so mild that they were barely aware of it, and they recovered within a few days."

Then the child noticed that several cows had smallpox-like cowpox, and the child had a bold guess......

"Most of the cattle infected with smallpox infected with smallpox infected the staff, and the smallpox on the cows is very light, not to death, and as long as the staff will produce antibodies after being infected once, they will be permanently immune, and the children will extract the virus from the cowpox and make this vaccine......

"And then you're going to try it yourself?"

The more he listened, the more he admired his son's wisdom, Xu Yuanhong's face suddenly sank, "Why do you despise your life so much!?" ”

Xu Tian said in his heart that it was time to show his acting skills, and said awe-inspiringly: "Practice is the only way to demonstrate conjectures, and children must do this!" First, the child can't care about people's lives and experiments on other people's lives, and secondly, the child just uses the illness to make Prince Gong dare not mention marriage again. As it turned out, the kid was right. ”

"Nonsense!" Xu Yuanhong's face flushed, and he said angrily, "Nonsense! You actually treat your own life as child's play! ”

Having said that, Xu Yuanhong was overjoyed in his heart.

How did you come up with the idea of using cowpox as a vaccine?

And he killed two birds with one stone, taking advantage of the plague, forcing Prince Gong not to dare to propose marriage.

What kind of people have such talents?

Is this really my son......

Xu Tian smiled and said, "Father is angry, don't you see that my adventure is quite fruitful?" ”

"Not again next time!"
