She married a dying prince and she won three babies.

"At that time, we sent the person with smallpox into the civilian population. I guess many people in Wei were also infected with smallpox. They took control of the military camp, and the next step would definitely be the civilians.

Send someone to pretend to be a civilian and find out how they are controlling it. Then spread the smallpox to me more widely, and I will see how many people they can control.

If they are famous doctors, just kill them and bring back their prescriptions for treating smallpox."

His Royal Highness the Crown Prince had such a perfect plan, but it was actually ruined by someone. The more he thought about it, the angrier he became.

He originally wanted to be awarded a title and become a general after returning to the capital based on his military achievements.

They were about to force them to surrender, but their plan failed because the Wei Dynasty opened the iron box.

"Yes, General." The deputy general received the order and immediately made arrangements.

They also had patients with smallpox, who were imprisoned in a secret place and guarded by soldiers who had survived smallpox.

He found a few dying old men and women among the people, infected them with smallpox, and then entered the Wei Dynasty from a remote place.

The soldiers who took them there were also carefully selected and assigned important tasks.

Shangguan Ziqi led his troops to attack Canglan City, while Yu Yuanzheng retreated to Lin'an City with a few guards to vaccinate and treat the people.

The civilians were easier to control than the army, but fortunately, there were not many of them, but there were still more than 20,000 of them.

The prefect, Lord Li, also returned, and he also followed the army out of Lin'an City.

Once it was recovered, he would come back to preside over the return of the people.

Now that smallpox has broken out, he is extremely anxious, but he has no other choice but to isolate people.

Lin'an City was occupied by enemy troops. There was nothing left in the city, and the people who returned did not bring back much supplies.

There were a few doctors, and although they were also afraid of contracting smallpox, the prefect forced them to participate in the treatment.

Fortunately, they knew how to protect themselves, and only one person was infected, and the others were fine.

The prescription had been sent back from the military camp long ago, and the doctor treated the sick civilians according to the prescription given by Yu Yuanzheng at that time.

But the effect is not obvious. It can only make the patient feel better. If the patient cannot survive, the final result will be death.

Shangguan Ziqi had already given the order not to burn the patient but to do his best to treat him.

"Zeng Shenzhi, you are finally here." Lord Li personally went out of the city to welcome Yu Yuanzheng.

Lord Li had been looking forward to her coming, but the army was more important. He had to ensure that the soldiers could defend the border first.

"Okay, find a place and bring all those who are not sick in batches. I will treat them one by one first."

"Okay, okay." Lord Li immediately went to make arrangements.

Shangguan Ziqi had sent five hundred soldiers to assist the prefect, and they were now his errand boys.

Several tents were set up on the street outside the yamen.

It's open and the place is big.

As soon as the guards delivered the cowpox fluid, Magistrate Li immediately brought the people forward.

Of course, he had already been vaccinated in the military camp in advance. He had to ensure that he would not be infected, otherwise how could he preside over the overall situation in Lin'an City? This was the benefit that Shangguan Ziqi gave to officials in various cities.

He is fighting in the front, so there can't be chaos behind.

When the people heard that the miracle doctor only needed to make a small wound on the shoulder and then apply some special medicine prepared by the miracle doctor to prevent smallpox, they all became very enthusiastic.

However, the miracle doctor's medicine was limited in quantity and could only be supplied to a certain number of people each day. There were even several fights among those who did not have smallpox in order to be the first to drink it.

But Yu Yuanzheng had no choice, that was all she could do.

Fortunately, some are delivered back every day.

Those cows are all given special protection.

The guards would buy it directly from the county magistrate or the mayor and find a place to raise it.

Take the juice regularly.

But the demand is too great, and people in several cities still need to be vaccinated.

Yu Yuanzheng suddenly thought of a way to increase the juice.

She slapped her forehead, wondering why she hadn't thought of this solution before?

If she could just infect healthy cows with cowpox, wouldn't she have endless amounts of juice to draw from?

Yu Yuanzheng immediately wrote down a method for infecting cows with cowpox and gave it to each guard who returned.

After the guards learned this method, they were able to deliver more juice within a few days. And they didn't have to travel too far.

With enough juice, the people returning to Lin'an City were quickly vaccinated.

Then the number of people infected with smallpox every day really dropped, and after more than ten days, there was no one infected.

Of those who were already infected, although some died, at least half survived.

When they finally walked out of the ward shrouded in illness, they saw that the people of the city, regardless of gender, age or status, had returned to their normal lives.

Smiles returned to everyone's faces.

In the streets and alleys, the cries of vendors and the laughter of children are intertwined, forming a vivid and warm picture.

This was not at all the scene they had heard of after the smallpox epidemic.

Once smallpox broke out, the entire city would fall into endless darkness and despair, as if it was permanently shrouded in the shadow of death.

And at this moment, what they saw was as if the first breeze of spring gently blew by, and all things revived and became full of vitality.

The epidemic in Lin'an City is under control, and Yu Yuanzheng is preparing to go to the next city. Now that there is no shortage of juice, she plans to speed up her pace.

But when she brought her people out of Lin'an City, she met an unexpected person.

"Divine Doctor Zeng, this county lady has finally found you."

It was Lady Xiangling who had hurried to the border.

Smallpox had broken out in several cities ahead, and all the city gates were closed, preventing people from entering or leaving the city.

She had to go around the city, which wasted her a lot of time, otherwise she would have arrived earlier.

She was also pulling two carts of medicinal herbs.

She bought it specially when she was about 800 miles away from the border, and came to see Doctor Zeng on the pretext of providing medicinal materials to the border.

Look, how much she thinks.

Yu Yuanzheng, riding on the horse, is still dressed in the same outfit as before, a loose navy blue gown commonly worn by doctors, a square hat, and of course a mask.

She wears this outfit every day.

Until now, no one has seen her true face as a miracle doctor.

"Why are you here? Who asked you to come?" Yu Yuanzheng wiped his forehead.

How did this abnormal woman come to the border?

What time is it now?

Smallpox was still spreading.

Is she seeking death?

"Doctor Zeng, I'm here to deliver medicinal herbs. Look, I've brought two large carts of medicinal herbs to you." Hua Xiangling stood by the carriage door and pointed to the two carriages carrying goods at the back.

It was obvious that she was being escorted by the ten strong men she was protecting.

"Leave the herbs here, and go back the same way you came." Yu Yuanzheng was furious.

What a clueless young lady.

"I'm not going back. I want to help you. You can guarantee that I won't be infected with smallpox, right?

Look, I brought so many people with me, and they can all help you.

Besides, you don't even have a maid by your side, so I can cook for you, wash your clothes, and take care of you, so you will have more energy to treat illnesses and save lives."

Hua Xiangling's attitude was very firm.

How could she possibly go back after coming so far?

The purpose of her coming here was to follow the miracle doctor, and this time she would never let him disappear and never be found again.

Yu Yuanzheng felt even more headache after hearing her words.
