Princess, he is rich enough to rival the country

With a little knowledge of movable type printing, glass and other things, only a little bit of knowledge, because of a little hobby in the past, Gu Yanshu's understanding of vaccinia vaccine can be said to be like a treasure.

Naturally, it includes not only the history of Dr. Jenner's discovery of vaccinia, but also the initial extraction and evolution of vaccinia vaccine.

These knowledge reserves, which seem to be useless in later generations, play a key role at this time.

For Gu Yanshu now, time is even more important than money.

Gu Yanshu's understanding of the vaccinia vaccine made him no longer need to blindly call a few imperial doctors together, tell them the vague thoughts in his mind, and let them explore the vaccinia vaccine according to their own ideas.

Now Gu Yanshu only needs to tell Yu Liren the steps of making the vaccinia vaccine, and let him extract the vaccinia from the calf in the shortest time.

After experiencing alcohol and wound sutures, Yu Liren felt more convinced by Gu Yanshu.

Although he held a skeptical attitude towards the fact that vaccinia could prevent smallpox infection, seeing that Gu Yanshu's attitude was too firm, Yu Liren still extracted the vaccinia vaccine as instructed by Gu Yanshu.

Even because the method given by Gu Yanshu was too detailed, the whole process from Yu Liren's preparation to the final extraction of the cowpox pus took less than a day.

Even knowing that compared with smallpox, cowpox can already be said to be very safe.

Even knowing that even according to the ability of Tianqi imperial physician, it is not difficult to cure cowpox.

However, after looking at the vaccinia pus extracted by Yu Liren and placed in a small glass bottle, Gu Yanshu's mind still inevitably flashed through the materials he had read. Dr. Jenner's early vaccinia vaccination After the human body, there have been various sequelae and fatal cases.

But in the next moment, the information in Gu Yanshu's mind was smashed by the expedited [-]-mile letter from Yizhou last night——

"There was an epidemic in Yanglin County, Yizhou, which was suspected to be smallpox. Since the prince returned from Yanglin County three days ago, he had a high fever and was suspected to be infected..."

Thinking of these words and the meaning behind the words, Gu Yanshu closed his eyes slightly, and put the small glass bottle back in Yu Liren's hand:

"Plant."

While speaking, Gu Yanshu had already lifted up his sleeves, revealing a clean arm.

After more than half a year of unremitting morning exercises, Gu Yanshu at this time is no longer as weak as before, and his arms are no longer so slender that people feel that they can be broken with a little effort.

Instead, it is covered with a thin layer of just-right muscles, which are not exaggerated at first glance, but the lines are extremely smooth and natural.

In future generations, this is what girls like most, with a body that looks thin and fleshy when undressed.

Not to mention a girl, even when Qin Lu showed that thin layer of muscles on Gu Yanshu's body, he seemed to be fond of it.

But it's a pity that no one is in the mood to appreciate Gu Yanshu's training results now.

Yu Liren was almost frightened by his princess's words, and directly threw the glass bottle containing the vaccinia pus in his hand to the ground:

Although the princess directly explained the purpose and method of use of the vaccinia pus from the beginning, His Highness never said that he would use this product on himself!

This bottle of pus was extracted from the calf by Yu Liren himself, and no one knows what is going on with this thing better than Yu Liren.

It was Yu Liren, who was disgusted when he did it, but now that Gu Yanshu asked Yu Liren to plant it directly on his body, how could Yu Liren dare to do it so easily?

"Your Highness, this... I'm afraid it's not appropriate."

Looking at Gu Yanshu who kept urging him with his eyes because he didn't move his mouth for a long time, Yu Liren said hesitantly:

"Before this subordinate, I have never heard of anyone using this method to prevent smallpox, and I don't know what will happen if this product is used on people. Your Highness is a noble person, and this subordinate really dare not take risks."

That's all for outsiders, who in Prince Li's mansion doesn't know how much the prince cares for the concubine?

If he really used this item that had never been tested on human body before, if something went wrong in the end, even if ten of his heads were chopped off, he would not be able to pay for it.

"I haven't heard of it before, haven't I heard of it now?"

Gu Yanshu held his forehead slightly. If it were at any other time, he would have asked Yu Liren to find someone to test it first, to prove the safety and reliability of the vaccinia vaccine.

But now, even if Gu Yanshu is willing to wait if he has time, Qin Lu who is far away in Yizhou can't afford to wait.

Gu Yanshu didn't want his own people to go to Yizhou, and he could only listen to the news related to Qin Lu from the people below, but he couldn't see it with his own eyes and take care of his own deer.

Seeing what Yu Liren wanted to say, Gu Yanshu directly added another sentence:

"You plant it directly. If there is any problem, the hall will take care of it."

Even if Gu Yanshu said so, Yu Liren still didn't dare to take risks.

No matter what Gu Yanshu said, Yu Liren insisted on experimenting on other people first, and after confirming that the method of vaccinia vaccination was safe and effective, he would use it on Gu Yanshu.

At the end of the dispute, Gu Yanshu saw that the soft and Yu Liren couldn't make sense, so he simply changed his strategy:

"Since this hall can tell you about the extraction method of cowpox directly,┭you can extract it by yourself. If you don't vaccinate this hall now, this hall will have to do it yourself."

"But Dr. Yu should also know that there is a specialization in surgery, and this hall is completely ignorant of medical skills. If something goes wrong, Mr. Yu thinks that you can get away with it?"

Of course not!

Almost instantly, Yu Liren already had the answer in his mind.

If something happens to Gu Yanshu on the way to Yizhou, not to mention him, even the people in the ┬持吹渌fu will be punished!

Not to mention that the vaccinia pus needs to be extracted from a cow suffering from vaccinia, and at the beginning, this calf was brought back to the palace by Yu Liren himself in full view.

At that time, if something went wrong with the princess herself, how could Yu Liren get away with it?

Looking up at Gu Yanshu's firm eyes again, Yu Liren realized for the first time what a dilemma is:

Inoculate His Highness, if something goes wrong, you will have to use your own wealth and life as compensation.

Don't vaccinate His Highness. According to His Highness's temperament, you can really do something yourself.

In contrast, it seems that he himself vaccinated His Highness himself, which is safer.

After thinking about it, Yu Liren finally had no choice but to grit his teeth and accept this grueling job:

"It's also okay to ask your subordinates to inoculate His Highness, but this subordinate has no experience in this matter. Before that, His Highness needs to inform his subordinates of the steps. After the subordinates test it on themselves, they will inoculate His Highness."

Yu Liren's idea of ​​making this request was simple.

No matter what the consequences of the vaccination on people would be, he and His Highness ┙ You Zheng would never make mistakes.

At that time, even if something goes wrong, he will be able to experience it more intuitively from himself.

Gu Yanshu thought for a moment, then nodded and agreed to Yu Liren's request:

"can."

Gu Yanshu's idea is also ┭simple:

Yu Liren is the doctor in Prince Li's mansion. After arriving in Yizhou, he needs to see Xiaolu's condition in person.

It is not difficult to understand from the information revealed by Yu Liren when he set off. Yu Liren had never been infected with smallpox before.

That is to say, there is no antigen in Yuliren's body to prevent smallpox infection.

Now we are standing together with him ┙ [-] gray 呙呙, and when we arrive in Yizhou, the antigens will almost appear in the body, and it will be much safer for Yu Liren to diagnose and treat Xiaolu.

Later, under the guidance of Gu Yanshu, Yu Liren vaccinated himself and Gu Yanshu with the vaccinia vaccine.

"After the vaccination, some uncomfortable symptoms such as low-grade fever may appear on the body, or some symptoms similar to smallpox may appear. At that time, there is no need to panic. It is a normal phenomenon. After the illness is recovered, the vaccination will be considered successful. "

Looking at the gauze wrapped by Yu Liren just now on his arm, Gu Yanshu did not forget to give Yu Liren a vaccination in a low voice.

"Yes, my subordinates understand."

If God gave Yu Liren another chance to choose, Yu Liren would definitely not trust Gu Yanshu so much and extract the cowpox pus from the calf.

No.

It should be said that Yu Liren would never choose to bring the calf suffering from cowpox back to the palace.

However, now that the cowpox has been inoculated to Gu Yanshu, the matter is a foregone conclusion. Now Yu Liren has no other choice but to believe in Gu Yanshu.

Even so, Yu Liren still dared not hide the fact that Gu Yanshu insisted on vaccinating against vaccinia.

After leaving Gu Yanshu's carriage, he directly reported the matter to Zhi Ge in detail.

Before Zhi Ge had time to react, Mei Yanxi, who was not far away from Zhi Ge, ┭ Yu Liren's words clearly, couldn't hold back, and opened his mouth first:

"You are so brave! Can this kind of thing be used casually on His Highness?"

Mei Yanxi didn't know exactly what cowpox was.

But from Yu Liren's description, it can probably be heard that it is not a good thing.

The result is such a thing that can be called salty, Yu Liren even dared to verify it or not, so he directly used it on Gu Yanshu, how could Mei Yanxi not be angry?

Yu Liren┭ is an old man who follows Qin Lu, so he naturally knows Mei Yanxi, the strong lady, very well.

┲虚暌话进话 For this hot-tempered young lady, Yu Liren was also ┭ very afraid.

Now being held accountable by Mei Yanxi pointing her nose, she is as quiet as a quail, not daring to say a word.

Zhige, on the other hand, has been by Gu Yanshu's side for a long time, and he understands Gu Yanshu's temperament.

But after a while, the key point was revealed:

"But Your Highness insists?"

"Yes."

Yu Liren hastily cupped his hands, taking what Gu Yanshu had just threatened him to do himself.

In the end, there was inevitably a trace of annoyance in the words:

"Although the method of extracting the vaccinia pus is simple, it needs to be processed later. Your Highness has no experience in this area before, and this subordinate is also afraid that if His Highness refuses, he will do it rashly, and there will be some irreparable mistakes."

Mei Yanxi didn't know Gu Yanshu very well.

Apart from those rumors in the market, there was only a quick meeting when Liu Ruxi was seeing off outside the city that day.

On that one side, it was she who was talking and Gu Yanshu was listening.

Now listening to Yu Liren's words, even if he is as grumpy as Mei Yanxi, he has nothing to say.

┦Pump fee barrier σ Bu⑾Zheng

This seemingly gentle Highness Princess Li doesn't seem to be as easy-talking as she appears on the surface?

But after being a little surprised, I felt that it was reasonable for Gu Yanshu to say such threatening words:

If Her Royal Highness Princess Li was really as gentle and harmless as ┧ showed, she would not have given Liu Er such a bad idea at the beginning, and she would not have thought about it when the news of Yizhou came. A decision has been made to go to Yizhou in person.

With Mei Yanxi's mind full of speculation about Gu Yanshu, Zhi Ge only glanced at Yu Liren lightly:

"Is the vaccinia pus still there?"

"and also."

When Yu Liren heard the words, he took out the glass bottle from his arms without thinking about it.

The glass bottle was only about the size of a grown man's finger, and the vaccinia pus was barely half full, so it wasn't much.

But the vaccination of vaccinia vaccine does not require much vaccinia pus. Relatively speaking, this small half bottle of vaccinia pus is not a small amount.

After Zhi Ge held the small glass bottle in his hand and looked at it for a while, he collapsed without thinking about it.

"Catch me too."

"what?"

In any case, Yu Liren never thought that he was just a report, and there was one more person who asked for vaccination.

"According to Wang Hao's temperament, if you are not fully sure, you will not be allowed to do it."

Zhi Ge took a light glance at Yu Liren, who was always taciturn, making people more patient:

"Now that the concubine has personally tested it, how can we, as subordinates, have any reason to escape?"

"If there are any serious consequences after the vaccinia vaccination, I will not be dereliction of duty if I wait to accompany His Highness."

"If this vaccine can really prevent smallpox, after the results come out, we will inevitably need to be vaccinated. So what if it is sooner or later?"

I have to say that what Zhi Ge said is indeed reasonable.

Isn't that why Yu Liren asked Gu Yanshu to vaccinate first?

"That's right! Your Highness has now set an example. I will be vaccinated sooner or later. So what if it's earlier or later?"

At this time, Mei Yanxi also recovered from her own thoughts, and looked at Yu Liren firmly:

"Besides, if the vaccinia vaccine really has the effect of preventing smallpox, wouldn't it be better to be vaccinated earlier?"

In the words, there was even the meaning of letting Yu Liren vaccinate him.

Before Yu Liren could speak, Zhi Ge gave Mei Yanxi a disapproval.

"What are you doing for fun?"

Rights and obligations have always been equal, since Mei Yanxi does not have a serious official position, the constraints on her body are naturally much smaller than that of Zhi Ge.

Even if Mei Yanxi doesn't follow Gu Yanshu's footsteps and get the vaccinia vaccine together, even if something goes wrong afterwards, outsiders will not be able to tell a single mistake.

"What? Do you allow me to use it or not? It seems that whoever you are talking about is not the right-hand man of the prince. Don't forget, this lady is on the same level as you."

Mei Yanxi glanced at Zhi Ge without even thinking about it:

"If it weren't for those bastards running so fast back then, you would have to call Miss Ben 'Master' now!"

Of course Zhi Ge knew what Mei Yanxi meant.

Seriously speaking, Mei Yanxi was recruited by Qin Lu a whole year later than Zhige.

But even this year later, Mei Yanxi has climbed to the same level as Zhi Ge, which is enough to show that Mei Yanxi's promotion speed is fast.

If the speed of the enemy's withdrawal of troops was a few months later, Mei Yanxi's current authority in the army might really stop the fight.

Now that Mei Yanxi has said such things, how can Zhi Ge say other words of dissuasion?

In the end, he could only follow Mei Yanxi's wishes and ask Yu Liren to inoculate her with vaccinia.

Zhi Ge didn't speak anymore, but Yu Liren couldn't help persuading him:

"Miss Mei has thought it through. His Highness once said that the location of the inoculation will probably leave a scar, which may be difficult to heal."

Everyone in the world said that Mei Yanxi had a fierce personality, she didn't like red clothes and preferred armed forces.

But what girl doesn't like red makeup?

Mei Yanxi is no exception.

Yu Liren still remembers how Mei Yanxi looked at him nervously and asked if the scars on his body would leave scars when Xirong was defeated and the dangerous pass was regained.

In Mei Yanxi's words at the time, it was "this lady's temperament has already become like this, if her body is not good-looking, how can she kidnap a son-in-law for this lady's father?"

Mei Yanxi, who has always been carefree and informal, patiently followed Yu Liren's instructions and applied various ointments to her wounds over and over again, trying not to leave scars on her body.

Now in Yu Liren's hand, there are several doses of healing and scar-removing holy products, all of which were developed for Mei Yanxi.

Seeing that Mei Yanxi is so persistent now, Yu Liren has no choice but to persuade her.

Sure enough, after hearing that there would be an incurable scar, Mei Yanxi showed the slightest hesitation on her face.

But soon, this trace of hesitation disappeared, leaving only a face full of determination:

"What's the scar left by vaccination? If you get smallpox, it would be ugly to have scars all over your face! Give it to Miss Ben!"

Now, Yu Liren was completely speechless.

After all, what Mei Yanxi said was true, after many patients suffering from smallpox were cured, they would leave dense scars on their faces, and it was extremely difficult to heal.

This time, in order to take better care of the prince, among the group of people brought out from the mansion, two of them were cured after suffering from smallpox.

As for the names of these two people, Yu Liren can't remember clearly. He only remembers that others called them "Wang Mazi" and "Li Mazi", which is enough to show the influence of smallpox on people.

Originally, Yu Liren thought that at most he would vaccinate Zhi Ge and Mei Yanxi.

Who knew that when Yu Liren reported to Zhi Ge just now, the movement was a little louder, and the adjutant who was not far behind Zhi Ge heard it all.

Not long after, Gu Yanshu developed an item called "Vaccinium Pox", which could prevent smallpox infection, and the news spread throughout the guards of Prince Li's Mansion.

Unlike Yu Liren who specializes in medical skills, he can maintain absolute sanity in his own field.

All the guards in Prince Li's mansion believed in Gu Yanshu unconditionally.

In their eyes, as long as it is an object from the hands of the princess, there must be no mistakes!

As for what Yu Liren said has not been verified by other people, I am afraid there will be some serious consequences?

The guards in Prince Li's mansion said:

We just want to ask you a question, just now the adjutant heard that the princess has been vaccinated in person, is this statement true or false?

it is true?

Then what's the cost?

The concubine has tested it herself, so do I need someone else to test it?

Immediately, everyone surrounded Yu Liren, demanding vaccination against vaccinia.

And those people brought by Mei Yanxi, after seeing the actions of the guards in Prince Li's mansion, also followed suit.

He said that being able to be recognized by the brothers in the palace so much, it must be unmistakable.

Besides, they have all seen it just now, and the eldest lady has also been vaccinated.

The eldest lady has already tested the object, is there anything wrong?

Immediately, like those guards who were drunk, they surrounded Yu Liren one by one, demanding to be vaccinated against vaccinia.

Poor Yu Liren, a delicate and frail little old man, how can he survive these strong men who practice martial arts all the year round, are five big and three rough, and can kill a child with one punch?

In the end, it was good to say that there was not much vaccinia pus, and it could not meet the requirements of everyone for vaccination.

He also said that after vaccination, there will be a period of physical discomfort. If everyone is vaccinated against vaccinia, then everyone will fall ill, and no one will be able to protect the safety of the princess, so he persuaded the guards in the mansion and Mei Yan The people brought on the evening of the evening were vaccinated in two batches.

The first batch of people who were vaccinated have responded, and then the second batch of people will be vaccinated.

The guards of Prince Li's Mansion and the strong men brought by Mei Yanxi made such a big commotion that it was difficult for the imperial doctors who came out of the palace to ignore it.

Several imperial doctors did not follow Prince Li's residence alone.

In order to ensure that the imperial doctors can reach Yizhou safely, and knowing that Qin Lu took a lot of people with him when he left the capital, there may not be many people that Gu Yanshu can mobilize now.

Therefore, in addition to nearly ten imperial doctors, the emperor also gave Gu Yanshu a team of imperial soldiers to protect him.

Now that the imperial doctors heard the people from Prince Li's Mansion and Mei Yanxi making noise outside, they couldn't help but sent a few Imperial Forest Army to investigate the situation.

The Imperial Forest Army sent by the emperor was also capable. Even though the people in Prince Li's Mansion saw that there was not enough cowpox pus, I was afraid that this group of Imperial Forest Army would also come to rob them, and did not answer their questions.

But the Royal Forest Army still deduced the cause, process and result of the incident from the few words of these people's discussions and Yu Liren's actions.

I went back and reported the matter to several imperial physicians. The imperial physicians heard that there was actually a way to prevent smallpox in Prince Li's Mansion. Even if they couldn't sit still, they found Yu Liren directly and wanted to find out.
