Princess, he is rich enough to rival the country

The process of going to the palace to ask for an order was smoother than Gu Yanshu imagined.

Almost no time after he declared his intention to buy it, the emperor agreed to his request.

Although before receiving the imperial decree, the emperor looked at him with eyes that Gu Yanshu couldn't understand for a while, but no matter what, the emperor finally gave him the imperial decree allowing him to go to Yizhou.

The emperor not only gave him an imperial edict, but also asked him to take away half of the imperial doctors in the imperial hospital.

When Gu Yanshu received the decree, he listened to the meaning of the prince, if it wasn't for the fact that the Imperial Palace had to keep the Imperial Physician, the Emperor even wanted to send the entire Imperial Hospital to Yizhou.

Gu Yanshu didn't know what the emperor was thinking when he received the news, and he didn't want to think about what the emperor looked at him before making the decree.

But when he heard Wang Gonggong's words, Gu Yanshu knew that at least for a moment, Qin Lu might be more like a father and son than a monarch and minister to the emperor.

After receiving the imperial decree, the things that should be arranged have already been arranged last night, and the next things will be much simpler.

When Gu Yanshu brought the imperial physician back home to change his clothes, he saw Zhi Ge and others ready to go.

only……

"Just now Yu Liren said that the princess told him something before entering the palace, and he needs to deal with it. He hasn't come back yet."

Seeing the figure of Gu Yanshu returning, Zhi Ge's eyes lit up, and he hurriedly stepped forward to report.

Although after seeing Gu Yanshu's orderliness last night, Zhige knew that no matter what his princess told Yu Liren, he had his reasons.

But Yu Liren is one of the few doctors in Prince Li's mansion, so he needs to take him with him when he goes to Yizhou this time.

Now people have been away for more than half an hour, seeing that the princess has come back from the palace, Yu Liren still has no news, how can Zhi Ge not be in a hurry?

"Before I went to the palace, I did tell him to do something very important. We will set off when he comes back."

Gu Yanshu saw what Zhi Ge was thinking at a glance, and Dang even gave Zhi Ge a reassurance:

"Don't worry, I have already explained before going to the palace, no matter whether the things I explained are completed or not, he will return to the residence within an hour."

Sure enough, upon hearing Gu Yanshu's words, Zhi Ge's complexion immediately relaxed a lot:

Now that the concubine has said so, according to Yu Liren's temperament, she will definitely come back within an hour, and since Yu Liren left to the present, it is only an hour away, and it is only two cups of tea away.

Sure enough, Gu Yanshu had just changed the dress he wore when he entered the palace, while Yu Liren had already returned to the palace.

Yu Liren left the mansion at this time, and Gu Yanshu said that it was important to tell him what to do.

This time when he returned to the mansion, he naturally attracted the attention of many people in the mansion, who wanted to see what Yu Liren was doing when he went out.

Looking at it, it really makes people see the difference.

Without him, the main reason is that the extra object in Yu Liren's hand is too conspicuous.

This man left empty-handed, but when he came back, he brought back a half-sized calf, which made it difficult for people not to notice.

and many more……

calf?

Could it be that the princess asked Yu Liren to do something, just to buy a calf?

But in this situation, what can a calf do?

It can't be that my princess feels greedy, and it's too late for Yu Liren to help find rations, right?

Just when everyone felt that they couldn't understand the actions of Liren and Gu Yanshu, Gu Yanshu, who had just changed his clothes over there, also saw the calf beside Yu Liren.

"Huh? Did you find it?"

Looking down at the calf, a trace of surprise flashed in Gu Yanshu's eyes.

Since Gu Yanshu is familiar with the smallpox virus, of course he also knows how to prevent it.

Now... no, it should be said that until later generations, when the United Nations announced the complete disappearance of the smallpox virus, the smallpox virus has always been in a state of being only preventable, not effectively curable.

As for preventive measures, it is vaccinated against vaccinia.

As we all know, people who have had smallpox and recovered from the disease will have antigens in their bodies, and they will never be infected by the ceiling virus for life.

The principle of preventing smallpox virus is to let people produce antigens against smallpox virus in the body to immunize against infection.

However, because of the lethality of smallpox virus, and people have not found effective cure measures, the method of using smallpox to make the human body produce antigens is obviously not applicable.

In later generations, the British surgeon Jenner accidentally discovered that the milking girl on the dairy farm was able to remain immune to smallpox virus infection when smallpox was prevalent.

Later, through observation and experiments, it was found that there is a disease called "vaccinia" that can be transmitted to humans in cattle, which has the same origin as smallpox.

And these milking girls were infected and cured by cows suffering from vaccinia during the milking process, and their bodies produced antigens against smallpox.

This discovery undoubtedly brought countless hopes to the time when smallpox was raging.

After all, compared with smallpox, cowpox is much milder and easier to cure.

The vaccinia was extracted from cattle and inoculated into humans to make the human body produce antigens against smallpox. This is the famous vaccinia vaccine in later generations.

Now Gu Yanshu doesn't know what the situation of his own deer is like, nor does he know how many people are infected with smallpox in Yizhou.

The greatest effort Gu Yanshu can do now is to stop the loss in time and extract the vaccinia vaccine as soon as possible to prevent more people from being infected with smallpox.

The vaccinia vaccine, above all, requires finding a cow, preferably a calf, that has the disease.

But at this point in time, how easy is it to find such a calf?

Therefore, before Gu Yanshu went to the palace, he just asked Yu Liren to try his best to find it.

If you can't find it, then look for it on the way to Yizhou, or after arriving in Yizhou, and you can always find the right one.

However, what Gu Yanshu didn't expect was that Yu Liren really brought back a calf when he went out this time.

"My subordinates were lucky. Without asking a few families, I found a calf that met the requirements of the princess."

Seeing that Gu Yanshu's gaze was always on the calf beside him, Yu Liren quickly replied in a low voice.

In Tianqi, although cowpox is not rare, it is definitely not common.

Therefore, when Yu Liren heard that Gu Yanshu wanted to find a calf suffering from cowpox, he felt a little uncertain.

In the end, who knew that this really made him catch up, so he went to the market and asked a few families, so he asked:

"It's also a coincidence that I'm going down. I heard that the family is going to find a veterinarian."

If he went a little later, maybe this cow would not meet Gu Yanshu's requirements.

"Let's go, let's talk about other things while walking on the road."

Gu Yanshu took another look at the calf, and then signaled Zhi Ge to tell people to set off immediately.

According to Gu Yanshu's original plan, he planned to ride a horse directly and rush all the way to Yizhou.

But now that there is this little calf and a few imperial doctors who are pampered in the palace, this idea is obviously no longer applicable.

As for those imperial doctors' delicate and expensive appearance, they really made them ride horses all the way, maybe they fell ill before they arrived in Yizhou.

At that time, let alone take care of their own deer, Prince Li's Mansion will have someone to take care of them.

In the end, Gu Yanshu simply asked Zhi Ge to hitch two carriages, and put the imperial doctor and the half-human-tall calf down.

Everything was ready, Gu Yanshu and his party were just about to set off when they heard a slightly familiar voice not far away:

"I'm not late, am I?"

Looking for the reputation, Gu Yanshu saw at a glance a group of people riding tall horses not far from Prince Li's mansion.

At first glance, that pedestrian made people feel fearful. His body was strong, his muscles were well defined, and the weapons he held at his waist or in his hands all showed his extremely unfriendly attributes.

Only the one with the big head, slender and slender, wearing a red riding outfit, with a symbolic long whip pinned to his waist, was the Miss Mei that Gu Yanshu had only seen at the city gate a few days ago.

But at this time, what is she here for?

"It was my subordinate who informed Miss Mei to come over."

Sensing the doubt in Gu Yanshu's eyes, Zhige at the side hurriedly told him in a low voice:

"Your Highness can take away too few people this time, and it's inconvenient to deploy manpower in the army..."

As soon as Zhi Ge's words came out, Gu Yanshu understood the meaning.

When Qin Lu went to Yizhou, he had already mobilized nearly half of the manpower in the mansion.

This time when Gu Yanshu went to Yizhou, there were not many people who could be transferred, let alone people who couldn't live without knowing how many secrets there were in the palace.

In the end, Gu Yanshu only took a dozen or so people away from the palace.

These dozen or so people are more than enough to deal with the thieves Xiaoxiao encountered on the road, or the bandits blocking the road.

But for the people on the side of the First Prince, Zhi Ge had to be on guard.

After all, ever since the news spread that all the novelties in the palace were made by the concubine, the eldest prince's dislike and hatred for Gu Yanshu has been no less than that of Qin Lu himself.

In the past, it was nothing more than Gu Yanshu's stay in the capital. With Prince Li's mansion in the end, and under the eyes of the emperor, what the eldest prince wants to do needs to be weighed.

Now that Gu Yanshu took the initiative to go out of Beijing, and only brought so many people with him, isn't it just a chance to send it to the First Prince himself?

With the inconvenient deployment of manpower in the army, Zhi Ge naturally thought of Mei Yanxi.

Sitting on an equal footing with him, but he has no official position, and there are a few useful people under his command, and none of them are members of the army.

Even if the eldest prince knew about it, he still couldn't find a trace of fault.

"She knows everything about the situation in Yizhou?"

When Gu Yanshu heard this, he raised his brows slightly.

Qin Lu contracted smallpox in Yizhou, which shows that the situation in Yizhou may not be optimistic.

Going to Yizhou now, there is definitely a risk of being infected. Gu Yanshu is not a person who likes to force others.

When selecting candidates to go to Yizhou with him yesterday, he also explained everything clearly.

Now that Zhi Ge called Mei Yanxi, Gu Yanshu naturally wanted to ask one more question.

Mei Yanxi over there also heard Gu Yanshu's question, and before Zhi Ge could answer, she gave the answer first:

"Your Highness, don't worry, Zhi Ge has made it clear to his subordinates."

Gu Yanshu raised his eyes to observe, and after confirming that there was no reluctance on the faces of Mei Yanxi and the people behind her, he nodded slightly:

"In that case, let's go."
