When Fang Yuan saw Li Shimin, it was almost dark.

When Fang Yuan arrived, Fang Xuanling, Eldest Sun Wuji and the others were all there.

Seeing everyone's solemn expressions, Fang Yuan felt that something was wrong.

"Li Ke urgently reported that smallpox had occurred in Hebei, and some people in the army were infected, and they urgently sought a solution."

Li Shimin took a deep breath and said in a deep voice.

When the words fell, the faces of everyone at the scene changed, revealing a panicked look.

Smallpox is a plague, extremely contagious, with a great mortality rate, and there is no cure for it at present.

"Now Li Ke is blocking the news and controlling the infected soldiers."

"But this is not a long-term solution, and the soldier will always know one day."

"Everyone, way!"

Li Shimin said in a deep voice.

Someone in the army of 50,000 was infected.

Those 50,000 troops may have been infected.

Any one of these people walking into a crowded place is a devastating blow.

Although Li Ke has temporarily controlled the situation now, sooner or later it will be known to the soldiers.

Once known, the army will get out of control, and 50,000 people will bring a devastating disaster to Datang.

"How can smallpox occur?"

Fang Xuanling was shocked, and his voice trembled slightly.

The best thing to do for smallpox is to isolate them from those who come into contact with them, and let them live and die.

But 50,000 troops, how to isolate?

"Don't worry about the reason yet, I want to hear a solution!"

Li Shimin said a little impatiently.

The crowd was even more uproared, still shocked.

"Your Majesty, the minister has been secretly executed for every infected soldier!"

Li Jing said suddenly.

The voice fell, and the scene was silent.

"No!"

"They are all heroes who fight for Datang, and they can only be isolated at most."

Liu Zhenghui, the secretary of the Criminal Department, immediately objected.

Many people also nodded and agreed with Liu Zhenghui's idea.

"How is the 50,000 army isolated?"

"If the news leaks during the blockade of news, the 50,000-strong army will be in chaos, and the military order will be bullshit at that time, and it will be the people of the world who will be harmed!"

Li Jing said in a deep voice.

Quarantine can only be used for a small number of people.

When there are many people, isolation does not work.

When the soldiers knew that some of them had smallpox, they would flee in disarray.

The escape will definitely go into a place where there are people, then the infection will expand and the situation will become more serious.

It is so serious that it may endanger the whole of Datang.

"Now I don't know how many of the 50,000 troops are infected, if all the 50,000 troops are infected, will they all be killed?"

"And if the execution of an infected soldier is known to other soldiers, it will also be chaotic, and it may even be worse."

Liu Zhenghui continued to refute Li Jing.

This time, Li Jing just opened his mouth and didn't say any more.

"Is there any other way?"

Li Shimin took a deep breath and said in a deep voice.

Li Jing's method can be tried to isolate all infections, but it is too extreme and may be as Liu Zhenghui said.

The crowd bowed their heads and fell silent, helpless against the sudden appearance of smallpox.

Smallpox appears in history, either to isolate or to kill the source of infection.

But now 50,000 troops, how to deal with it?

"Your Majesty, we have the Medicine King!"

"Is it possible that the Medicine King knows how to crack smallpox?"

Eldest Sun Wuji suddenly said excitedly.

Li Shimin's eyes suddenly lit up and looked at Fang Yuan.

The rest of the people did the same, and they also looked at Fang Yuan one after another.

"Your Majesty, ladies and gentlemen, what do you think I mean?"

Fang Yuan pouted.

If you think that the King of Medicine may have a way to crack it, then look for the King of Medicine.

"Go, please don't ask the medicine king, you can move to the Fang Mansion with me."

Li Shimin immediately wanted to invite Sun Simiao.

But before he finished speaking, he changed his mind,

He took the minister of the humerus to see Sun Simiao and asked Sun Simiao to make a move.

In this way, it can be seen that Datang values him and urgently needs him to take action.

"Your Majesty is wise!"

The ministers spoke one after another.

Follow Li Shimin and go to Fangfu together.

By the time everyone came to Fang's Mansion, it was already dark.

Du Miaoyan and the others were shocked when they knew that Li Shimin had brought so many ministers over.

They greeted the arrival of Li Shimin and others.

"Is Dr. Sun back?"

Fang Yuan asked.

"Just came back, in the living room."

Du Miaoyan replied.

Fang Yuan hadn't said anything yet.

Li Shimin and the others walked towards Fang Yuan's living room.

Du Miaoyan looked at it, her face full of curiosity, and asked what was wrong with Fang Yuan.

After listening to Fang Yuan's explanation, Du Miaoyan's face suddenly changed, and she looked afraid.

"Medicine King, please save the people of the world!"

As soon as Li Shimin appeared, he said humbly.

"Please save the people of the world from the king of medicine!"

The eldest grandson Wuji and others also saluted.

Sun Simiao originally drank tea in Youzai.

After seeing Li Shimin and others come in, he was immediately surprised.

When he saw the emperor and his ministers saluting him, he jumped up in fright, and the tea spilled on his clothes, wetting them.

"Fa, what's going on?"

Sun Simiao stammered.

"There was smallpox in Hebei, and soldiers in the army of 50,000 were infected."

Li Shimin said in a deep voice.

"Smallpox?!"

Sun Simiao was shocked, and his eyes widened.

There are too many legends of smallpox in history, and every time it comes out, there are countless deaths.

"Yes, please also ask the Medicine King to help."

Li Shimin nodded solemnly and looked at Sun Simiao nervously.

He was worried, worried that Sun Simiao would say that he had no choice.

If Sun Simiao can't do anything, who else in the world has a way?

50,000 troops, if there is chaos at that time, it will not be a problem of 50,000.

"Your Majesty, you invited the wrong person, the old man has no choice."

Sun Simiao shook his head and said.

He had several visits to smallpox patients and wanted to find a cure for smallpox.

But alas, he failed and failed to figure out the method.

"How so."

Li Shimin and the others suddenly became disappointed.

Even Sun Simiao can't help it, so who else has a way, it's so desperate.

"That. I actually have a way to protect against smallpox. ”

Fang Yuan hesitated for a moment and sighed.

Everyone was stunned and looked at Fang Yuan one after another, thinking that they had heard it wrong.

"I actually have a way to defend against smallpox."

Fang Yuan sighed.

He didn't really want to say it.

Because he only knows that there is a kind of cowpox, but he doesn't know how cowpox comes from.

In this case, he may need to go to the front line in person to determine how to find cowpox.

Now that Du Miaoyan is just pregnant, and the front line is so dangerous, Fang Yuan really doesn't want to go.

But there was no way, Sun Simiao had no choice, Fang Yuan could only stand up.

After all, it was 50,000 soldiers, and once it was chaotic, it would not be as simple as 50,000.

"What did you say?"

Li Shimin said in a trembling voice.

At this moment, he suddenly remembered that Fang Yuan was his Ying Mengxian minister.

Since it is his own Ying Mengxian, can he help him get through the difficulties again?

After all, Fang Yuan had successfully helped himself a few times before, so there should be no surprise this time, right?

Including Sun Simiao, everyone looked at Fang Yuan, and everyone was shocked and incredulous.

"I said, I have a way to defend against smallpox."

Fang Yuan rolled his eyes and sighed.

"Good, good, good!"

"Fang Yuan, as long as you succeed, you will be the hero of my Datang!"

Li Shimin said excitedly.

Ying Meng Xianchen, sure enough, he is worthy of Ying Meng Xianchen!

"Fang Xiaoyou, what can you do?"

Sun Simiao asked.

He studied smallpox for a long time, but he did not come up with a method.

Fang Yuan is not a doctor, he actually knows the method of defense?

It wasn't that Sun Simiao didn't believe Fang Yuan, but that he wanted to know how to defend himself?

Everyone also looked at Fang Yuan nervously, eager to know how to defend against smallpox.

"Smallpox can be passed not only to people, but also to cattle and sheep, and so on."

"In some of the cattle that got smallpox, they were able to heal and leave cowpox."

"By planting cowpox on people, you can achieve defense and no longer be infected by smallpox."

Fang Yuan said in a deep voice.

This is the principle he knows.

But how to find cowpox is still a problem.

"What is cowpox?"

Sun Simiao's eyes lit up and asked.

He remembered going into a smallpox-infected place.

The people there are all dead, but you can still see some cattle and sheep in captivity.

Cows and sheep can be infected with smallpox, so why didn't they die?

At that time, Sun Simiao noticed this, but he didn't think about it so deeply.

Now listening to Fang Yuan's words, he suddenly had an idea.

"I'm not sure what cowpox is right now."

"I need to go to Hebei."

Fang Yuan said in a deep voice.

When the words fell, someone immediately objected.

"No!"

Du Miaoyan said sharply.

She didn't want Fang Yuan to go to Hebei.

She didn't want Fang Yuan to have an accident.

"I don't want to go, but it's 50,000 troops."

Fang Yuan looked at Du Miaoyan and sighed.

He's a selfish guy and really doesn't want to take risks.

But that's 50,000 soldiers, and the impact is likely to expand.

"Miao Yan, Fang Yuan will be fine!"

"Yes, Fang Shilang will be fine!"

"Girl, relax your heart, Fang Yuanfu has a big life, and he will definitely be fine."

Li Shimin and others immediately comforted Du Miaoyan.

Knowing that Fang Yuan had a way and wanted to go to the front line, they were all very supportive.

Du Miaoyan opened her mouth, and finally left with red eyes.

This was the first time she had been in an emotional mood since she had been married to Fang Yuan for so long.

And in front of the emperor and a number of ministers who are the pillars of the country.

But Li Shimin and others have no opinion, and they can even understand it.

After all, Du Miaoyan is pregnant now, and Fang Yuan is righteous.

"Fang Xiaoyou, the old man will accompany you!"

Sun Simiao said suddenly.

He wanted to study smallpox again.

Let's see what the cowpox in Fang Yuan's mouth is.

Let's see if Fang Yuan really has a way to defend against smallpox.

"Fang Yuan, without further ado, let's leave tonight?"

Li Shimin asked tentatively.

Although it was night, it was a bit difficult to get there.

But this time I went to Hebei for several days.

And that's an army of 50,000, I don't know how long Li Ke can control it.

Eldest Sun Wuji and the others looked at Fang Yuan with blank eyes, and they also hoped that Fang Yuan would set off tonight.

"I'll leave after dinner."

Fang Yuan said after pondering for a moment.

Since you've decided to go, let's go early.

After all, the later it is, the worse it is for yourself.

"Good!"

"I'll send you personally!"

Li Shimin was greatly excited and said in a deep voice.

"Fang Shilang, I'll send you too!"

Tang Jian also agreed.

Seeing this, the eldest grandson Wuji and others said to send Fang Yuan.

Fang Yuan nodded, without too much nonsense, and said goodbye to everyone to find Du Miaoyan.

"Husband, do you really want to go?"

"That's smallpox that no one can solve!"

Du Miaoyan stared at Fang Yuan and said worriedly.

The red floc Qingyu and Xue Jiaoyan and others in the house are there.

They all looked at Fang Yuan worriedly, worried about the danger of Fang Yuan's departure.

Among so many people at the scene, only Xue Jiaoyan wanted Fang Yuan to go.

After all, Xue Bowu was still on the battlefield, and he didn't know what the situation was.

"Don't worry, I really have a way."

Fang Yuan comforted.

After a while with Du Miaoyan, I went to eat.

At this time, Li Shimin and others were also waiting for Fang Yuan at the dinner table.

They hadn't eaten yet, so they took the opportunity to eat at Fang Yuan's place.

"Fang Yuan, Doctor Sun, a glass of wine, go early and come back early!"

Li Shimin raised his glass and said in a deep voice.

The eldest grandson Wuji and others also raised their glasses and bid farewell to Fang Yuan.

"Thank you."

Fang Yuan took a cup and feasted on it.

He felt that Li Shimin and the others were a little tragic and didn't want to pay attention to them.

At this time, no one would blame Fang Yuan's ugly appearance.

I would only feel that Fang Yuan was really temperamental, and I couldn't wait to go to the front line.

It's just that Sun Simiao is bitter, and he can't eat it so quickly, so he can only stuff it in.

After the meal was full, Du Miaoyan also prepared things for Fang Yuan and Sun Simiao.

One carriage, two horses.

This is the royal car of the palace, and Li Shimin is riding.

There are also ten masters who escorted Fang Yuan and Sun Simiao to Hebei.

Originally, horseback riding was the fastest.

But considering Sun Simiao's age, Li Shimin changed the carriage.

"Farewell, everyone!"

Fang Yuan and Sun Simiao got on their horses and left quickly.

Li Shimin, Du Miaoyan and the others watched Fang Yuan's back disappear into the night sky at the door.

"Let's all go back."

"Miaoyan, if you have something, you can go directly to the palace to find me."

Li Shimin retracted his gaze and said in a deep voice.

Fang Yuan left for the sake of Datang, he didn't allow anyone to bully Fang Mansion during this time.

"Thank you, Your Majesty."

Du Miaoyan returned home.

Everyone stepped back.

On this night, many people couldn't sleep soundly, but the reasons were not necessarily the same.

The other side.

On the car.

Fang Yuan and Sun Simiao sat opposite each other.

"This frame is worthy of being a royal car."

Sun Simiao sighed.

It is soft under the buttocks and is comfortable to sit on.

Two people ride, there is still a lot of space, and sleeping at night is not a problem.

"The emperor's things are naturally good."

Fang Yuan said half-leaningly.

He looked a little dazed, thinking about where the cowpox came from?

"Fang Yuan, how did you know that cows have cowpox on their bodies to protect against smallpox?"

Sun Simiao asked.

He was still curious about how Fang Yuan knew how to defend against smallpox.

"More on that later."

"I'm wondering how I can get cowpox."

Fang Yuan was in no mood to answer Sun Simiao.

It is impossible to tell Sun Simiao the real reason.

After all, that's a method that will only appear in later generations, and it is not available yet.

"Pox, as the name suggests, is pimples, pimples, pustules."

Sun Simiao thought for a moment and explained with his own medical knowledge.

"Pustules?"

"I probably know."

Fang Yuan's eyes suddenly lit up.

I thought of where the cowpox might come from.

Afterwards, Fang Yuan chatted with Sun Simiao about defense.

It also allowed Sun Simiao to use his medical knowledge to make masks.

Although the effect is not as good as that of later generations, it is barely usable.

It can play a certain defensive role.

After a few days, Fang Yuan and Sun Simiao finally reached their destination.

But by this time, the barracks had rioted.
