It is not particularly difficult to find cows that are infected with cowpox, and one cow can be used to vaccinate countless people.

"yes."

Out of seventy people, Yu Yuanzheng only kept Chunlei and four others to accompany her to the border.

When Yu Yuanzheng arrived at the border, it was already fifteen days after Shangguan Ziqi sent the letter.

"Ma'am, I'm sorry. Your husband has made you suffer."

When Shangguan Ziqi saw the dusty Yu Yuanzheng, he apologized with heartache.

"Alright, we are husband and wife, so there is no need to talk too much. Just ask the emperor for more rewards for me in the future."

Thinking of the house, Yu Yuanzheng was very satisfied.

You can’t buy it even if you have money.

"Besides, I am also from the Great Wei. Canglan is so vicious and wants to destroy my peaceful life. Can I agree to it?"

Yu Yuanzheng hated the Canglan people for their disregard for human life.

Even the common people were not spared.

This is a ruthless move that will bring about being struck by lightning.

"Madam said yes.

My husband has isolated all those infected with smallpox.

But it still failed to stop the spread of smallpox.

Half of the enemy's prisoners of war have been infected, and more than 3,000 of our soldiers have also been infected.

There have been deaths in prisoner camps, and in several cities after the capture, there have also been infections among the returning civilians.

Fortunately, there were not many people returning home, so the speed of infection was not too fast.”

Shangguan Ziqi briefly talked about what had happened during these days.

"I was so anxious at that time. Did the emperor send any edict?" Yu Yuanzheng came empty-handed, and their speed was definitely not as fast as the imperial edict.

"The emperor has already sent a royal physician on the way, and has organized people to deliver medicinal materials. But I don't know whether the medicinal materials delivered are suitable." Shangguan Ziqi said truthfully.

"Okay. I'll make another list and ask our nearest pharmacy supplier to ship some over."

In the face of national crisis, this is not the time to worry about so many things. Let’s control the epidemic first.

The frontline is full of soldiers. Canglan wants to wear out the soldiers on the border of Wei Dynasty so that he can reap the benefits later.

At the same time, it also caused the Wei Dynasty to lose its composure.

Humph, do you think this vicious plan can stop the Wei cavalry? Wishful thinking, let's see how she breaks their plan.

The two of them talked as they entered the tent.

"My dear, find twenty people you can trust, and the four people from Qingfeng. I will arrange for them to get the cowpox immediately. There is no time to lose."

Yu Yuanzheng didn't even have time to rest.

"good."

Shangguan Ziqi immediately asked Qingfeng to arrange personnel.

Soon, twenty strong men came out of the tent.

"My fellow soldiers, I have something important to arrange for you. You must do this in secret and not let the Canglan people find out."

Yu Yuanzheng then taught them how to identify poxed cows, how to extract the juice, and how to preserve it.

If you're not sure, just follow Qingfeng and his three companions.

The four of them had all seen how Yu Yuanzheng operated.

Moreover, the four of them have been vaccinated and are unlikely to get smallpox.

After receiving the order, Qingfeng and his three companions led their men to the nearest mountain village to look for cattle.

When the enemy invades, most villagers in mountain villages will not flee, but hide in the mountains. Only those in the city or the surrounding areas will flee.

After Yu Yuanzheng sent the people away and wrote a prescription, she finally relaxed the mind that had been tense for the past ten days.

After relaxing like this, I felt so tired that I just wanted to fall into bed and sleep.

She had been traveling for so many days, riding a horse the whole time.

My legs are numb.

"Madam, you take a nap first. I'll wake you up after Qingfeng and the others bring the things." Shangguan Ziqi picked her up with a distressed look and carried her into the inner room of the tent, where he rested temporarily.

During this period, in addition to making military deployments in case of enemy invasion at any time, he also had to control the spread of smallpox in the army as much as possible.

The military deployment was fine, but as for the control of the smallpox, he really couldn't control it completely.

The number of people infected is increasing every day.

He had placed each tent as far apart as possible, but he still couldn't control it.

Yu Yuanzheng was so tired that she fell asleep as soon as she touched the bed.

When she woke up again, it was already the next morning. She was awakened by hunger.

He wolfed down a large bowl of porridge and a pancake.

The food in the military barracks can't possibly be very good, it's just edible.

Yu Yuanzheng is not picky.

"Eat slowly. No one is going to snatch the food from you." Shangguan Ziqi advised gently.

Seeing her eat so fast, he felt even more distressed. He guessed that she had not had a proper meal during these days on the road.

"Okay, has anyone from Qingfeng come over?" Yu Yuanzheng put down his chopsticks and started asking about business.

"not yet."

We just set off yesterday afternoon, so it wasn't that fast.

"Report."

As soon as he finished speaking, the voice of the guards came from outside.

"Come in."

A newly transferred soldier came in.

"Report to the commander-in-chief, this is General Luo who sent someone to bring him here, but he ran away again after he was sent outside the camp."

It can be seen how hurried he was. He remembered Yu Yuanzheng's words clearly and went to get another batch immediately.

Shangguan Ziqi took it.

"As soon as there is any delivery, send it in immediately."

"Yes, Marshal."

"My dear, please set up a person to collect porcelain bottles at the city gate.

Pick them up as soon as they arrive and let them go again, it will be faster this way." Yu Yuanzheng suggested.

Now they are racing against time for their lives.

"Okay. I'll arrange it right away."

Shangguan Ziqi arranged several young generals with good kung fu skills to guard the city gate.

Later, when they learned that this thing was a miracle drug for curing smallpox, they went out to meet it. When they saw the person coming, they took the thing and ran quickly.

It also increases efficiency.

Received the first porcelain vase.

Immediately vaccinate uninfected people.

Chunlei, Xiayu, Zhuiyun and Zhuyue also had a night's rest and felt full of energy.

“You four, first watch how I operate and how to control the amount. When there is more juice later, you will have to take charge on your own.” Yu Yuanzheng planned to make the four of them work together.

It's simple, you can learn it just by looking at it.

It cannot be performed by non-military doctors.

"Yes, Xiaozi." The four people responded immediately.

In the military camp, Yu Yuanzheng continued to wear men's clothing.

He put on the mask to prevent spies from Canglan Country.

If her portrait was drawn and sent to Canglan Kingdom, she would be in danger.

Moreover, she appeared in the military camp as a miracle doctor, which was a great encouragement to the soldiers.

With her around, every soldier is more confident of surviving.

Even if it was smallpox, they held out great hope.

She was well-known in the Wei Dynasty, and many people knew her.

Shangguan Ziqi asked someone to notify all generals above the rank of lieutenant general to come to the tent.

He did not say what he had asked them to do.

Let everyone line up outside and wait to be called in one by one.

This is also what Yu Yuanzheng meant.

Don't tell them the reason, just get vaccinated silently.

She has done it many times and has become skilled in controlling the dosage. It will not have much impact on healthy people. At most, it will cause a low-grade fever, but people who don't care too much will not feel it.

A small bottle was finished by more than 200 people.

Everyone found it very strange that he only made a small cut on their shoulders, then wiped the wound with a cotton swab and told them to go.

There was a deputy general who was very familiar with Shangguan Ziqi and asked privately what this was doing.

In the end, Shangguan Ziqi only replied: "You will know it later."

That unfathomable look made the deputy general look confused.

As more and more juice was delivered, Yu Yuanzheng opened several tents, one for each of the four people in Chunlei, and let everyone come for vaccination in batches.

This process lasted for half a month before all the soldiers who had not been infected with smallpox were dealt with.

㹏If the acne juice can't keep up.

During this half month, the number of soldiers infected with smallpox continued to increase every day, but later on, the number of new cases decreased.
