Li Shimin touched his chin.

He was thinking, should he believe in Li Chengfeng?

He has never seen what kind of treatment this has been.

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

...

"Feng'er, do you think the injection you invented can really fight the plague?"

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

It was really unimaginable for him. Why was the plague that no one in the world could cure? Li Chengfeng was fine if he gave himself an injection?

Li Chengfeng patted his chest and said with confidence: "Yes, Father! The vaccine I invented is a liquid drug!"

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

There was some liquid inside.

Li Chengfeng said: "Father, look, this is vaccine medicine! So, I want to use a syringe, put these medicines in it, and then inject it into your body!"

"In this way, you can get antibodies from it and be immune to the harm of the plague! What's wrong, Father? Get the injection for free today, and I'll start charging tomorrow!"

"Ah? I'm going to charge money again?"

Li Shimin is still thinking.

He immediately asked again: "Feng'er, will this drug be injected into the human body? For example, dizziness? Disease, or death?"

Li Chengfeng said: "Don't worry, my father, no! Look, I've given all the people in the town palace a vaccine, and they have nothing to do! Do you want to get the shot? I'll just do whatever you want, I'll put it away if I don't get the shot!"

"Wait, I, fight!"

In the end, after a fierce ideological struggle, Li Shimin decided to get a vaccine.

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

Moreover, others also beat them, and there were no adverse reactions?

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

What can this mean?

This shows that the drugs developed by Li Chengfeng are effective!

"Okay, how to play?"

"Rolle your sleeves!"

"Then what?"

"Then, it's an injection!"

Li Chengfeng smiled slightly.

Is it an injection to the emperor!

Scare him to death!

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

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

As the emperor of the Tang Dynasty, he had the obligation to test the law with his own heart.

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

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

The survival of the Tang Dynasty can be said to be in the hands of Li Chengfeng.

Now, it depends on whether Li Chengfeng's medicine is effective!

Li Chengfeng took the cotton, stained with some alcohol, and applied it to Li Shimin's arm.

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

Li Shimin laughed loudly.

However, at this moment, Li Chengfeng suddenly stabbed the needle.

“Huh?”

"Oh, it hurts! Little bastard, do you want to murder me?"

When the needle pierced into Li Shimin's arm, Li Shimin suddenly felt excited.

He was not afraid of this pain, but was afraid of sharp objects piercing into his body.

Injection is actually not very painful, and no one has ever had a knife.

But many people have phobia for injections.

For example, Li Shimin himself.

After getting an injection, coupled with your inner fear, the pain instantly doubled!

Li Shimin never wants to try this feeling again!

"Okay, Father, get it done!"

When Li Chengfeng pulled out the needle, Li Shimin then breathed a heavy sigh of relief and smiled: "Haha, that's all!"

"But Feng'er, my body, didn't feel any strange existence?"

Li Shimin asked.

Li Chengfeng said: "It's right not to feel it. If you can feel something strange? It proves that there is something wrong with your body! Don't worry, my father, this is a normal manifestation!"

"Oh, that's good!"

Li Shimin touched his breath and burst into laughter!

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

That's great!

...

Immediately afterwards, Li Chengfeng gave Wei Zheng, Wang Dequan and other ministers one by one a shot of the vaccine.

Although, vaccines are not worth it.

But, getting injections is a technical job and it is very tiring.

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

Because, great doctors are kind-hearted.

It’s not like you do anything, you need to charge money.

The greater the ability, the greater the responsibility.

Since you have the ability and can help others resist the existence of the plague, you can help them heal for free.

This is Li Chengfeng, who is accumulating merits for himself!

...

Soon, all the people in the town palace had finished the injection.

Li Shimin stood in the middle of the crowd and said, "My ministers, how do you feel about your health?"

"It's not that strange!"

"Well, the Eighth Prince told me that this is a normal manifestation! If anyone is feeling unwell, remember to say it out loud! It's not a joke in the face of the plague! Fortunately, the Eighth Prince is there, otherwise, this plague will probably break out of the entire Chang'an City, or even the entire Tang Dynasty!"

"Yes Emperor!"

I don’t know if I don’t say it, I’m shocked when I say it!

Yes, if the plague really raged the Tang Dynasty and no one could treat this condition.

So, how long can Li Shimin live so that he will not be infected with the plague?

So how long can the entire Tang Dynasty last so that it will not perish?

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

"Feng'er, I want to ask you for a while now, how about it?"

Li Shimin said calmly.

Li Chengfeng said: "Father, please say it! Don't ask me, I will do what I can do naturally!"

Li Shimin felt very relieved and said, "Okay, Feng'er, I hope you can save the entire palace and all the people in Chang'an City. How about it? The current plague is only a lurking stage and has not erupted in full! Once it breaks out in full, I guess the entire Chang'an City will fall into panic!"

"At that time, those who die will die, those who are injured will die! Countless people will die!"

"Of course there is no problem with this! However, saving the Tang Dynasty cannot be solved by the power of Erchen alone! So Father, you send ten imperial physicians first and come to my place! I will teach them the skills of injections, provide them with needles and medicine bottles, and let them practice medical skills in the folk! Otherwise, with my own power, I can't stand it at all!"

"Okay, there is no problem with this! Feng'er, your kindness and kindness will definitely leave a thick ink in the history of the Tang Dynasty! I will let the historian record all your stories in history and pass on them for future generations, how about it?"

"Well, just do it as you like!"

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

He just wants to have a clear conscience and be happy!
