Li Shimin touched his chin.

He was thinking, should he trust Li Chengfeng?

What kind of treatment method is this? He has never seen it before.

Can you fight the plague by pricking yourself with a needle?

…

"Feng'er, you said that the injection technique you invented can really fight the plague?"

Li Shimin touched his chin and looked at Li Chengfeng suspiciously.

It was really unimaginable to him. Why could Li Chengfeng be fine after giving himself a shot of a plague that no one in the world could cure?

Li Chengfeng patted his chest and said in assurance: "Yes, Father! The vaccine I invented is a liquid medicine!"

Li Chengfeng took out a small glass bottle from a small box on the table on the left.

There is some liquid inside.

Li Chengfeng said: "Father, look, these are vaccines and medicines! So, I am going to use a syringe to load these medicines, and then put them into your body!"

"In this way, you can obtain antibodies from it and become immune to the harm of the plague! How about it, Father? The injection is free today, and starting tomorrow, I will start charging for it!"

"Ah? Are you going to charge money again?"

Li Shimin was still thinking.

Immediately he asked again: "Feng'er, will there be any adverse reactions if this drug is injected into the human body? For example, dizziness? Disease, or death?"

Li Chengfeng said: "Don't worry, Father, it won't happen! You see, I have vaccinated everyone in the Prince's Mansion, and nothing has happened to them! Do you want to be vaccinated? It's up to me if you don't want to be vaccinated.

Just put it away!"

"Wait a minute, I'll fight!"

Finally, after a fierce ideological struggle, Li Shimin decided to take a shot of the vaccine.

He believed in Li Chengfeng's medical skills and believed that Li Chengfeng would never harm him.

Moreover, others have also been given the injection and there have been no adverse reactions?

I heard that Princess Changle fell ill suddenly yesterday, with fever all over her body and nosebleeds, but she is fine now.

What does this mean?

This shows that the medicine developed by Li Chengfeng is effective!

"Okay, let's fight, how do we give it a fight?"

"Roll up your sleeves!"

"Then what?"

"Then, it's time to get the injection!"

Li Chengfeng smiled lightly.

Giving the emperor acupuncture!

Scared him to death!

"Well, that's fine, then come on!"

Li Shimin took a deep breath and finally decided to accept the vaccine.

As the emperor of the Tang Dynasty, he had the obligation to test the law by himself.

If this vaccine is really effective, it can really resist the plague.

Then in the future, I can let Li Chengfeng save the entire ministers in the palace, and even the entire people of Chang'an City!

The fate of the Tang Dynasty was entirely in Li Chengfeng's hands.

Now, let’s see if Li Chengfeng’s medicine has any effect!

Li Chengfeng took cotton, stained it with some alcohol, and smeared it on Li Shimin's arm.

"Oh, it's so comfortable, so refreshing, so refreshing, and it doesn't hurt at all, hahaha..."

Li Shimin opened his mouth and laughed.

However, at this moment, Li Chengfeng suddenly stabbed him with a needle.

"Huh?"

"Ouch, it hurts, it hurts! You little bastard, do you want to murder me?"

When the needle penetrated into Li Shimin's arm, Li Shimin suddenly felt a shock all over his body.

He was not afraid of the pain, but he was afraid of sharp objects piercing his body.

In fact, the injection is not too painful, and no one has experienced the pain of a knife.

But many people have injection phobia.

For example, Li Shimin himself.

The injection, combined with the fear in my heart, doubled the pain instantly!

Li Shimin never wants to try this feeling again!

"Okay, Father, it's done!"

When Li Chengfeng pulled out the needle, Li Shimin breathed a sigh of relief and said with a smile: "Haha, that's all!"

"But Feng'er, I don't feel any strange presence in my body?"

Li Shimin asked.

Li Chengfeng said: "Just don't feel it. If you can feel something strange? That means there is something wrong with your body! Don't worry, father, this is a normal symptom!"

"Oh, that's good!"

Li Shimin felt his breath and laughed!

In other words, Li Shimin now has antibodies and is no longer afraid of the plague.

So, so good!

…

Immediately afterwards, Li Chengfeng vaccinated Wei Zheng, Wang Dequan and other ministers one by one.

Although it is said that vaccines are not valuable.

However, giving injections is a technical job and very tiring.

Moreover, this time Li Chengfeng did not accept their money.

Because the great doctor is kind-hearted.

Not everything you do requires payment.

It is said that the greater the ability, the greater the responsibility.

Since you have the ability to help others resist the plague, you can help them treat it for free.

This is Li Chengfeng, accumulating merit for himself!

…

Soon, all the people in the Zhenwang Mansion had completed their injections.

Li Shimin stood in the center of the crowd and said, "Ministers, how do you feel about your health?"

"There's not much difference!"

"Well, the Eighth Prince has told me that this is a normal behavior! If anyone is feeling unwell, remember to say it! Facing the plague is not a trivial matter! Fortunately, the Eighth Prince is here, otherwise, this plague will probably

Erupting the entire city of Chang'an, and even the entire Tang Dynasty!"

"Yes Emperor!"

I don’t know if I don’t tell you, but I’ll be shocked when I tell you!

Yes, if a plague really ravages the Tang Dynasty and no one can cure this disease.

So I would like to ask, how long can Li Shimin live without being infected by the plague?

So how long can the entire Tang Dynasty persist before it perishes?

It can be said that Li Chengfeng has silently saved the existence of the Tang Empire this time!

"Feng'er, I want to beg you once now, how about it?"

Li Shimin said calmly.

Li Chengfeng said: "Father, please tell me! You don't have to ask me. Whatever I can do, I will do it naturally!"

Li Shimin suddenly felt very pleased in his heart and said: "Okay, Feng'er, I hope you can save the people in the entire palace and all the people in Chang'an City, how about it? The current plague is still in the latent stage, and there is no comprehensive

It breaks out! Once it breaks out in full force, I estimate that the entire Chang'an City will be plunged into panic!"

"When the time comes, everyone will be dead and injured! Countless people will die!"

"Of course there is no problem with this! However, saving the Tang Dynasty cannot be solved by my own strength! So my father, please send ten imperial doctors to me first! I will teach them the techniques of injection.

Provide them with needles and medicine bottles, and let them practice medical skills among the people! Otherwise, I won’t be able to withstand it with my own strength!”

"Okay, there is no problem with this at all! Feng'er, you are kind and kind, and you will definitely leave a strong mark on the history of the Tang Dynasty! I will let the historian record all your stories in the history books, for the sake of

How about it being passed down to future generations?"

"Well, Father, just do whatever you want!"

Li Chengfeng is not a person who seeks fame and profit.
