As long as I give you an injection, you will all have antibodies in the future, and you will be immune to this disease from happening to you.

So why not do it?

Besides, I, Li Chengfeng, don't even charge you!

Look at scaring you one by one.

As if I would kill you?

Li Chengfeng himself didn't get an injection, because Li Chengfeng has a system that is invulnerable to all poisons, so let alone viruses, even Gu worms can't help Li Chengfeng. Li Chengfeng eats it as protein, so what is he afraid of?

"Eighth Prince, slow down, slow down!"

"what…"

Immediately afterwards, Li Chengfeng went in with a needle, and Eunuch Wu yelled in pain.

Yelling, hurting, hurting!

Li Chengfeng frowned, and immediately shouted: "Why does it hurt? Are you a man? If you are a man, don't cry out that it hurts!"

"Eighth Prince, this old slave is disabled, this old slave is not a man!"

Eunuch Wu said aggrievedly.

Li Chengfeng sighed, and said: "Oh, I forgot about it! But it's all right now, Eunuch Wu, from now on, you also have antibodies. From now on, you will not be infected with this plague if you go in and out of the palace casually." ,do not worry!"

"Yes, Eighth Prince, thank you for saving my life!"

Eunuch Wu thanked him gratefully.

He knew that Li Chengfeng did this for his own good.

Because, Li Chengfeng himself used this kind of thing to heal the grown-up princess Li Lizhi yesterday.

Li Lizhi was infected with the plague, but was healed by Li Chengfeng within a day?

It can't be said that he is not powerful, he is simply a fairy doctor!

You can see how powerful Li Chengfeng's medical skills are when you look at Li Lizhi, who is alive and kicking around.

And Li Lizhi was also very lucky, fortunately, she fainted yesterday.

The injection doesn't hurt at all.

If it was an injection today, she would probably faint from fright.

If such a sharp needle is pierced directly into someone's arm, is it any wonder it doesn't hurt?

…

"Uh, Chang Le, what is your little brother Feng'er doing?"

Out of curiosity, Li Shimin also came forward and asked.

Li Lizhi turned her head to look, Li Shimin is here?

So Li Lizhi grinned and said, "Father, brother Feng'er is amazing. He has developed a vaccine that can solve the plague!"

"Oh? There is still a vaccine for the plague? Isn't it medicinal? What is a vaccine?"

"I don't know, but brother Feng'er said that the thing in his hand is called a vaccine, and it can solve all the plagues on us!"

"Oh? So powerful?"

Li Shimin touched his chin involuntarily and began to think.

Li Lizhi nodded, and said: "Yes, father, I was originally infected with the plague yesterday and fell ill. Later, brother Feng'er rescued me! Look, how healthy I am now? I don't have any sickness at all!"

"Well, yes, very good! But this way of vaccination is too cruel. Does it have to be injected?"

"That's right, everyone in the Prince's Mansion is queuing up for an injection. Father, hurry up too, it's really useful!"

"Hmm... let me think about it!"

To be honest, Li Shimin is very concerned about face.

In public, Li Chengfeng gave him an injection and was watched by so many people?

Li Shimin felt that he must have lost face.

So he planned to discuss with Li Chengfeng whether he could take him to a hidden place and get an injection.

He thought that he believed in Li Chengfeng's medical skills.

Moreover, Li Chengfeng studied under Shennong, so it can be said that he has received the true biography of the immortal Shennong. Even the imperial physician Duan He's medical skills are not as good as Li Chengfeng's. This is Duan He's own admission!

…

"Next!"

After giving Eunuch Wu an injection, Li Chengfeng shouted at the top of his voice!

At this time, a petite loli came to Li Chengfeng, her eyes showed fear, and she said, "Eighth Prince, you have to be gentle, I'm afraid of pain!"

"Well, don't worry Xiao Wu, I will be very gentle!"

Why?

Li Chengfeng always felt that it was a bit weird for him to say this?

Oh, she is just a simple little girl, what are you thinking about?

"Xiao Wu, who won't hurt very much, bear with it!"

"Um!"

After all, Li Chengfeng also gave Wu Xu an injection.

This is a vaccine that can effectively target the spread and spread of acute respiratory infectious diseases.

The incubation period of this disease is generally about seven days, and once the onset occurs, it is difficult to subside.

And it can be transmitted through breathing, so it is very scary.

But there is a vaccine, so there is no need to be afraid.

After giving Wu Xu the injection, Wu Xu looked at Li Chengfeng with his mouth curled up, and said, "Hmph, you said it didn't hurt, it hurts so much..."

Looking at this teary-eyed little lolita, Li Chengfeng felt a little embarrassed.

He comforted and said, "I'm doing this for your own good too!"

"I know, but it hurts, Eighth Prince!"

"Then, then I'll rub it for you and blow it on!"

After finishing speaking, Li Chengfeng really started to rub Wu Xu's arm!

"Does it still hurt? Xiao Wu?"

"Well, it's better!"

A happy smile appeared on Wu Xu's face.

Li Chengfeng even suspected that this little girl came here to comfort him on purpose!

Yes, Wu Xu, when you become my little daughter-in-law, how can you act like a baby?

…

"Brother, why don't you come in front of me? Shall I give you my place?"

Gao Chen suddenly said to Li Junxian behind him.

Li Junxian didn't squint, and said righteously: "I don't like to jump in the queue, and I don't like to owe favors. It's your turn, Gao Chen. Don't try to hide, everyone needs an injection! I need it too!"

Li Junxian said righteously ~lightnovelpub.net~ Gao Chen had no choice but to go forward to get the vaccine.

Although the injection was not very painful, everyone was terrified of the feeling of being pierced into the flesh by the needle.

This feeling doubles the pain.

So when Li Chengfeng gave the injection, Gao Chen trembled all over.

On the other hand, Li Junxian didn't react at all.

Instead, he smiled slightly, as if to say, "That's it?"

Just this little pain? Do you still have the nerve to yell?

I feel like I was bitten by a mosquito. Is this considered painful?

Yes, when Li Junxian's martial arts was abolished, he had 128 sword marks on his body, so that the scars on Li Junxian's body are clearly visible now!

Compared with those pains, what is the pain of an injection?

…

"Okay, everyone is done? It's time to call it a day! From now on, everyone can go out and run around, because you have been vaccinated and have antibodies, and the plague can't find you! So everyone can move around freely now!"

Li Chengfeng waved the needle in his hand, and popularized vaccine knowledge to everyone.

At this time, Li Shimin couldn't help coming forward with Wang Dequan, and said, "Feng'er, tell me, the vaccine you developed is really effective? Can it really solve the plague?"

"Yeah, father, why don't you come and get an injection? How about it? I'm really free!"

"Um…"??
