Cowpox!
In fact, Xie Yuan had considered many things when she was pregnant.
For example, prenatal checkups!
For example, the various vaccines a child receives after birth.
With experienced doctors like Physician Feng, prenatal checkups can be somewhat made up for.
Although we don't have instruments like ultrasound or echocardiography, regular pulse checks still have some benefits.
However, vaccines and such are more complicated.
In ancient times, when medical resources were scarce, even antibiotics were invented by Xie Yuan through dubious means.
As for diseases like smallpox and cholera, there was no cure and no way to prevent them.
Xie Yuan then thought of the essential skill for a transmigrated woman—smallpox vaccination.
However, Xie Yuan faces an even bigger problem.
She traveled to an earlier era, a time before smallpox even existed.
What Xie Yuan wanted to do was to skip human smallpox and go directly to cowpox experiments.
Fortunately, she had too many miraculous "precedents," and from Helian Jue to ordinary craftsmen, everyone had a very deep understanding of her extensive knowledge.
She briefly outlined her thoughts and explained the smallpox vaccination process, while other details were supplemented by Physician Feng and other imperial physicians.
While in Lingnan, Xie Yuan began to order preparations.
It must be said that Xie Yuan's status as the Princess Consort of Yue at that time gave her many advantages.
With a single order from her, her subordinates could search the entire Lingnan region, and even other prefectures and counties.
All in order to find a suitable sick cow.
Besides the sick cows, there were also people who cooperated in the experiments.
When the powerful clans of Lingnan plotted against Xie Yuan, they used prisoners from the jail.
This reminded Xie Yuan.
Xie Yuan followed the same method and found some death row inmates.
Of course, she didn't take any coercive measures; instead, she let those people make their own choices.
Those who are willing to cooperate with the drug trials and survive may be spared the death penalty.
If the person's crime is not so unforgivable, in addition to being pardoned, they can also be given a certain reward.
They might even receive a bonus if they regain their freedom.
This greatly excited the hardened criminals who were already outlaws.
They signed up with great enthusiasm and followed Physician Feng's experimental project team into a desolate mountain.
As for the possibility of dying if the drug trial fails, the hardened criminals didn't seem to care much.
Life and death are preordained, wealth and honor are determined by fate!
Overcome it, and you'll find freedom and wealth.
Even if you can't get through it, you'll still die, which is better than wasting your time in prison or being beheaded.
There were enough sick cows and strong live animals, but due to issues such as knowledge and understanding, the cowpox experiment was not very successful.
It wasn't until Xie Yuan set off to return to Beijing that a successful case emerged.
However, several rounds of experimentation are still needed to develop a mature technology.
Therefore, Physician Feng's experimental group was suspended and returned to the capital with the main force.
Physician Feng was very dedicated to treating smallpox. On the road, while others hurried along, he ordered people to search for sick cows or patients with smallpox along the way.
Without Xie Yuan's "reminder," Physician Feng actually managed to induce smallpox.
However, the risk factor of variolation is still very high.
Therefore, Physician Feng continued his frantic experiments on the sick ox.
Upon returning to the capital, Xie Yuan immediately arranged for the experimental group to reside at a manor on the outskirts of the city.
Zhuangzi is a closed system; once you enter, you can never come out.
Daily necessities, food, medicine, etc. are all delivered by designated personnel.
It's been almost a month, and there's still no good news.
Xie Yuan couldn't help but feel a little anxious.
You can't blame her for making a mountain out of a molehill, nor can you blame her for being timid; it's just that having a child has given Xie Yuan a weakness.
Not to mention, there are so many unstable factors in the palace.
The four little ones are too young. Not to mention smallpox, even a minor cold could kill them!
As a mother, Xie Yuan brought the children into this world, and she has a responsibility to do everything in her power to protect them.
"Yes! Your Majesty, I will have Physician Feng and the others expedite the experiments."
She wanted to see it for herself.
However, there were sick cattle and "patients" who had been vaccinated in the village, so the area couldn't be said to be teeming with viruses, and it was best to avoid going there as much as possible.
Xie Yuan wouldn't think she had an invincible aura just because she's a time-traveling woman.
She was just a mortal.
The only thing that sets him apart from the others is the historical knowledge he accumulated in his previous life for making TV shows!
And "prophet" or something like that is not a talisman.
If she is not careful, she will still get sick and die!
She is not alone anymore; she has four children. She cannot take any risks!
"That's too dangerous? Then let's not go!"
Helian Jue listened to Xie Yuan's explanation and nodded slowly.
He looked at Xie Yuan and gently advised, "A Yuan, you don't need to be too anxious!"
"This palace, this capital, and I am still here!"
Helian Jue knew that Xie Yuan was so anxious because it was all for the sake of the child.
However, the children don't belong to Xie Yuan alone; they also have a father.
And their father was the most honorable and powerful person in the world.
If Helian Jue couldn't even protect his own flesh and blood, he felt he shouldn't be an emperor.
"I have already ordered Duofu to place people in the palace."
Helian Jue did not hide anything from Xie Yuan.
In fact, even if Helian Jue hadn't said anything, Xie Yuan could have guessed it.
When older palace servants "retire," younger, new servants naturally take their place.
Apart from a very few spies planted by various families, most of these people were probably carefully selected by Helian Jue.
When young palace maids and eunuchs entered the palace, the first group they were assigned to were the Empress Dowager, the two empress dowagers, and the various imperial concubines and consorts.
The Yong'an Palace and Yongshou Palace of the two empress dowagers were of paramount importance.
Xie Yuan was willing to bet that with these palace maids, even if Empress Dowager Ashina was very cautious, Helian Jue could still keep track of her every word and action.
Needless to say, Xie Yuan also has arrangements on his side.
"Your Majesty, Yaoguang has sent a message!"
Back in the palace, Helian Jue went to the front hall to review memorials, while Xie Yuan handled palace affairs in his bedchamber.
Zheng Yurong, dressed in the attire of a female official, hurriedly entered and bowed in response.
"..." Xie Yuan didn't speak, but simply raised one hand.
Zheng Yurong quickly held the paper tube in both hands and placed it in Xie Yuan's hands.
The paper tube was only four or five inches long, with black paint on the outside and sealing wax at the opening.
The sealing wax was intact; no one had opened it without authorization.
This was one of the methods Xie Yuan used to send messages through his embroidered messengers.
Xie Yuan put forward the requirements, and Luo Peiyu, Zhao Jinxiu, and others implemented and improved them.
Xie Yuan peeled off the sealing wax, unscrewed the cap, and pulled out the slip of paper inside.
The notice simply read, "Consort Wang secretly meets with the Empress Dowager!"
Consort Wang was formerly Consort Wang, the birth mother of the fifth prince Helian Cong.
The Empress Dowager should refer to Empress Dowager Ashina.
How did they end up together?
It should be noted that Empress Dowager Ashina was extremely proud, and even the former Consort Xiao was treated as a lowly servant, let alone Consort Wang, who had an even lower rank.
When we were young, he was a rival in love.
As they got older, the two women put aside their past grievances and suddenly became "good sisters".
