The Empress of the Qing Dynasty is from the Northeast

The first thing Changning thought of was cowpox.

In fact, when her own child was vaccinated against smallpox, she had already discussed this matter with her eldest brother.

However, the development of cowpox is too dangerous and takes a long time. It will take at least two or three years to produce a relatively mild and safe vaccine.

Changhua had been researching for so long and had indeed achieved some results and progress, but who knew that Kangxi happened to go crazy and kill people everywhere, and the Eighth Brother and Soetu rebelled, so the research was delayed.

Changning felt that this matter could be put on the agenda.

Just as cowpox was developed, vaccination against smallpox would be safer for Hong Zhao and others.

But before Changning asked his eldest brother to come into the house, he heard a piece of news.

Nian Gengyao was appointed Governor-General of Sichuan, and now he has to return to Beijing in accordance with the Emperor's decree.

Nian Gengyao?!

Changning couldn't help but "tsk tsk" twice, this person is really well-known!

Because in the TV series Legend of Zhen Huan, his arrogant and domineering image has been deeply rooted in people's hearts. Even Concubine Su was manipulated by him and he directly rubbed the emperor's face on the ground.

Although Su Peisheng was very respectful to her now, Changning never had the intention of humiliating him. Su Peisheng was really loyal to Yinzhen, and was thoughtful and prudent in everything. She felt relieved to have such a person serving her.

Moreover, she discovered that although Su Peisheng was very powerful and prestigious in Prince Yong's Mansion, he never bullied others by taking advantage of his power.

Although the current Eunuch Su is not yet the chief steward of the Palace of Tranquil Longevity in the future, Changning is very optimistic about him.

But speaking of Nian Gengyao, Changning couldn't remember when Xiao Nian Gao came to power.

Today, she certainly would not be so wary and hostile towards the Nian family anymore.

She was confident that Yinzhen would not touch other women again, and the two of them had long been in love with each other and knew each other well.

But she also didn't want to delay the girl's life.

In history, Concubine Nian should have been a gentle person, and she gave birth to several sons for Yongzheng, but unfortunately they all died young.

This time, I hope she can find a good partner, someone who can love her, and live a happy life.

When waiting for Yinzhen to come back in the evening, Changning took the initiative to ask about Nian Gengyao.

Yinzhen knew that the power of the Fucha family in the court was gradually increasing, and that there was nothing special about Nian Gengyao. He also admired this man in his words. He thought he was capable, had some talent, and was a good leader of troops.

As for Changning's joking question about whether he wanted to win her over or marry her sister, Yinzhen refused without even thinking: "Why would I want to marry her sister? I don't need her. Besides, I have you, so why would I need anyone else?"

Changning snuggled in his arms with a smile and slowly told him about the cowpox.

"My third brother only heard about it from foreigners before. The smallpox vaccine can be obtained from cows that have smallpox, and then inoculated into humans. It is less dangerous than human smallpox. My eldest brother has also been experimenting on the farm for the past two years, and there have been some results. I want him to talk about it in detail. If cowpox can be successfully promoted, it will be safer for children to be vaccinated in the future, and the possibility of curing smallpox will be higher."

Yinzhen's eyes lit up: "Cowpox?"

"Yes, my brother has been researching it for two or three years, and I think the smallpox vaccine is relatively safe. I wanted to ask him about it, but I went to Mulan Paddock and encountered these things. But it's okay, you are a prince now, and some things will be easier to do."

Yinzhen nodded quickly, his tone slightly excited: "If the cowpox vaccine is really that effective, it would be a great achievement for the Qing Dynasty! Many people will not be helpless when they get smallpox in the future. God bless our Qing Dynasty!"

Changning was also very happy. At least this matter should be successful.

Yinzhen was really a career-oriented person. When he thought about the fact that cowpox could be more widely used and safer than human smallpox, he almost couldn't sit still and immediately wanted to write a petition.

Seeing him eager to try, Chang Ning couldn't help laughing: "It's so late today, go to bed early and write tomorrow."

Yinzhen had already gotten up and started to get dressed: "No, I've already started thinking about where to do the experiment. There are still some details that need to be finalized. You should rest first, don't wait for me too late, I'll just sleep in the front yard."

"Okay then." Chang Ning touched his stomach and indeed felt a little sleepy. "By the way, you are so busy now, I'm afraid Hong Yan and the others will have to find another master."

Yinzhen had thought about this matter a long time ago: "Don't worry, I won't neglect my sons' studies. I will take care of Honghui, but I'm afraid you need to pay more attention to Yierha. The wife has left her some dowry. Tomorrow I will ask Ma to pack it up and show you the list. If there is anything you need to supplement or fill in, just take it from my storeroom."

Speaking of dowry, Chang Ning immediately perked up, after all, she also has a daughter: "Okay, I've saved some for Hutu too, so I can compare and see if there are any mistakes or omissions."

Speaking of his daughter's marriage, Chang Ning asked about the Chen family's situation again: "That Chen Zhihuai has also made great contributions this time, is there any reward?"

Yinzhen noticed that Changning paid special attention to this boy, and thought: "Why? Are you really interested in him?"

"You think he's bad?"

"No, this kid is indeed very brave, and he deserves half the credit for this success. However, it seems that he is determined to fight on the battlefield. Although he is full of talent, he may not be able to take the path of a civil servant in the future. If he really leads the troops, becomes a general, and goes to the battlefield, what will Hutuli do?"

Changning had not expected this. Indeed, if Chen Zhihuai really guarded the border in the future, he and the Hutuli couple would be in different places. How could she bear to let her daughter suffer this?

It seems that he is not a good candidate either.

Changning began to look sad again, and Yinzhen kissed her cheek: "Okay, don't worry, there are many good men in the Qing Dynasty, don't worry about this one."

To cheer her up, Yinzhen said with a smile: "The Emperor gave me the Old Summer Palace, but I haven't visited it yet. This garden cannot be used directly, it needs to be repaired. Tomorrow I will ask Su Peisheng to bring the map. Take a look and write down anything you want and let them do it."

She likes this job!

Isn’t this just decoration?!

From what Yinzhen said, the renovation of the entire Old Summer Palace was carried out according to her preferences and wishes?

As soon as he saw her expression, Yinzhen knew what she was thinking: "Don't make major changes, just add in the ones you like slightly."

Oh, so that’s how it is!

But that was not bad. Changning was so excited that he could hardly sleep when he thought about leaving some designs in the world wonder, the Old Summer Palace.
