She married a dying prince and she won three babies.

"Oh? Doctor Shao, what do you want to see me about?" Shangguan Ziqi said as he was about to walk towards Doctor Shao.

"Marshal, please stay." When Doctor Shao saw Shangguan Ziqi approaching him, he stepped back.

Seeing him like this, Shangguan Ziqi had to stop.

"Tell me, what do you want from me?"

"Marshal, I've discovered a disease spreading from the prisoner camp that requires immediate attention." Doctor Shao didn't dare to name the disease, but his solemn expression told Shangguan Ziqi it was serious.

"What disease?" Shangguan Ziqi frowned.

"Smallpox." Doctor Shao did not say it out loud, but used mouth shapes.

He was afraid that if he spoke too loudly, the news would spread too quickly and destabilize the morale of the army.

"What did you say?" Shangguan Ziqi rushed to Doctor Shao and grabbed his shirt.

"Marshal, please stay away from me. I have come into contact with those people. It doesn't matter if I die, but you must not be in any harm." Doctor Shao almost cried as he pried Shangguanziqi's hands apart with force.

Shangguan Ziqi then let him go.

"Say it."

"Marshal, a number of prisoners in the camp have suddenly developed fevers these past few days. Then, some of our own soldiers also developed high fevers.

This morning, I discovered rashes on several people's foreheads, hairlines, and cheeks. I have determined that this is smallpox. I hope the Marshal will make a decision as soon as possible."

Doctor Shao ran away after saying this.

He was in such close contact with the Marshal, and he might have infected the Marshal. When he came to report, he was already prepared to die.

On the day the city was captured, he was assigned to treat the wounds of the prisoners.

There are more than 10,000 people, and he is just one doctor, so the workload is huge.

The captives could have been killed directly, but the Marshal did not do so. He said he would keep them and let Canglan use money to redeem them during negotiations later.

Just give him some porridge to keep him alive.

It took him three days to treat all the wounded, and many of those who did not receive medical treatment died from excessive blood loss.

But as captives, no one sympathized with them.

But those who had fever broke out collectively, so he had to take it seriously.

As a result, he discovered such a big thing. He was so anxious that he didn't dare to delay for a moment and went directly to report it to the commander-in-chief. He avoided people all the way because he was afraid that shouting it out would disrupt the morale of the army.

When Shangguan Ziqi got the news, he immediately called several main generals and notified them to find all those who had contact with the prisoners, and then gather all those with fever in one camp.

He also ordered the city gates to be closed immediately and the people were not allowed to enter the city.

All the military camps outside the city were checked.

Fortunately, not all the soldiers were allowed to enter the city, but one third of them camped outside the city.

When the generals learned that smallpox had appeared in the military camp, they all acted quickly.

After everything was arranged, Shangguan Ziqi took a deep breath.

"Prince, the princess has vaccinated us. Do you think that if we vaccinate all those who have not been infected, we can prevent the spread of the virus?" Qingfeng looked at his master with a worried look on his face and made a suggestion.

Shangguan Ziqi was thinking about this very question.

I'll have to trouble Madam again with this matter.

Hey!

“Okay, now that you’ve all been vaccinated, go investigate how this smallpox outbreak occurred and whether it’s an enemy conspiracy.

If this was an enemy conspiracy, then there must have been people who had smallpox among the prisoners, or they must have deliberately contracted smallpox to participate in the battle and be captured by us."

When Shangguan Ziqi thought of this possibility, his face turned so dark that ink could drip out of it.

If this was really the enemy's plan, he would make them pay a heavy price.

This is simply unscrupulous.

Treat human lives as ants.

Qingfeng found out the result of the investigation that day, just as Shangguan Ziqi had guessed.

Among the prisoners of war, ten soldiers were made to stay in a room with a sick man for two hours before the battle, and then they were left as prisoners in the city.

The promised benefit was that each of their families would be given fifty taels of silver, and after they were redeemed, they could enter the imperial city to serve as palace guards.

Fortune and wealth are achieved through risk, and this is a great thing, so of course they are willing to do it.

Only now did they realize that the patient in the same room with them was suffering from smallpox.

At that time, the man had not yet developed a rash, so they had no idea. They only knew that he had a fever.

Everyone is afraid of death. When they found out that they had smallpox, they realized that they had been deceived by their superiors.

This means they are already treated as dead.

Shangguan Ziqi was so angry that he sighed to the sky.

Now that things have come to this, we can only find a way to solve the problem.

He had no other choice but to ask his wife to come forward.

He immediately wrote an urgent letter of eight hundred miles back to Beijing to report to the emperor.

But the roof is leaking and it keeps raining.

A few days after his letter was sent, some of the people in the city that had been recaptured had returned, and smallpox broke out among them.

Shangguan Ziqi was so angry that he wanted to attack Canglan Kingdom right away.

In just three days, Yu Yuanzheng received the letter sent back by Shangguan Ziqi by express delivery, which was sent back together with the express delivery from Babaili.

This news caused an uproar in the entire capital.

Yu Yuanzheng hurriedly found the princess.

"Mother, my daughter-in-law must leave as soon as possible." Yu Yuanzheng didn't expect that the Canglan Kingdom would be so cruel.

This is to wipe out all the soldiers on the border of Wei.

This is unforgivable.

"Okay, pack your things and leave immediately. Take as many people as you can in the mansion with you. I know you need help. Go to Prince Jing's mansion to find your adoptive mother and ask her to send more people to you."

Without further ado, Yu Yuanzheng didn't even have time to say a few words to the children. She just told them to listen to their grandmother and not act naughty, and then she started to collect the things they needed.

Chunlei went to Prince Jing's mansion to ask for someone.

Prince Jing took away some of it, but not all of it.

When Princess Jing heard what Yu Yuanzheng was going to do, she immediately gave all the people she could, a total of thirty people.

While the emperor was still furious in the Golden Palace, Yu Yuanzheng had already set off with dozens of strong men from the Rong Prince's Mansion and the Jing Prince's Mansion.

First go to the princess’ farm outside the city and find Yang Zhuangtou.

Yang Zhuangtou actually kept the cow and treated it as a treasure. The strange thing is that the cow is still not well.

Upon asking, I found out that it had given birth to another baby, so it had contracted cowpox again.

All the young men who had not been vaccinated were treated with cowpox, and they set off immediately without waiting to observe their reactions.

It would take at least ten days to reach the border without stopping.

That's plenty of time for them to absorb the rash.

After leaving the capital, Yu Yuanzheng disguised himself as a miracle doctor.

It’s more convenient to wear men’s clothes. I guess she will have to stay in the military camp for a long time.

When they were still six hundred miles away from the border, Yu Yuanzheng stopped.

It only takes one or two days of fast horse ride from here to the border.

"My brothers, now you listen to my instructions.

Now, divide into groups of four, spread out, and go everywhere to find cows infected with cowpox.

Generally, cows or cows that have given birth are most likely to get cowpox.

Each of you has a token from the Prince Rong's Mansion and the Prince Jing's Mansion. Based on your identities, you can ask the local county magistrate or town mayor to help you find the cow.

You all saw before how I took the cowpox juice.

Take them out and put them in porcelain bottles, then send them to the border with ice. The more the better.

I'm waiting for the things you send in the barracks.

Time is of the essence and there is no room for error.

All the way to the border.

Keep it secret and don't let anyone know what you're using it for. If the Canglan people find out, they'll hold you accountable.

Remember?"

Yu Yuanzheng made arrangements.
