Du Jine's affairs finally came to an end. The dust settled, and the Yang family returned to peace. Everyone felt uncomfortable about the child Chai Mengying lost. However, things had already happened and the discomfort could not be restored, so life still had to continue.

"Sister Ying, don't do this. You have not eaten or drunk for several days. How can you bear it if you continue like this?" Xiaoxue sat beside Chai Ying's bed with a bowl of porridge. "Sister Ying, I'm sorry, I apologize to you for your recklessness." Although she was unwilling to admit that she was sisters with Du Jin'e, she could not abandon her blood relationship with her.

Mengying wiped away her tears: "What did you say? It's not your business. She is her, you are you, how can you compare? I don't blame anyone, I just blame myself. Why am I so stupid and I don't even know that I'm pregnant. I'm sorry to Liulang and the Yang family."

"That's not your fault, Sister-in-law said, you're only one month old. Didn't your mother say that women usually have pregnancy reactions after three months when they have a body? You didn't realize it wasn't your fault, so why would you blame yourself? Brother Liulang won't blame you, and parents won't blame you. They are more worried about your body than children. Brother Chai, he came several times and asked about your condition. You can't let him worry too, right?"

"Xiaoxue, will I have children in the future? I am so scared. What if...... what if this fall makes me unable to have children in the future?" Meng Ying held Xiaoxue's hand, with unpredictable fear in her eyes.

"Of course you will have children. Like his father and brothers, he will become a great hero to defend his country in the future." Yang Zongbao, the only descendant of the Yang family, was born by Princess Chai, so she was not worried that Chai Mengying would say that she would not have children.

"How do you know?"

"Can I predict the future," Xiaoxue reached out to wipe her tears, "Believe me."

"I believe you, don't worry, I will definitely take care of myself and will not worry everyone." Mengying took the bowl from her hand, and after drinking it, Xiaoxue helped her lie down and was about to leave. Luo's girl knocked on the door and came in. When she saw her, she whispered, "Xiaoxue, you are here, I have something to discuss with you."

"Sister-in-law, what's the matter?"

"Let's go outside and say, don't disturb Liu Niang's rest." The girl Luo looked at Chai Mengying who was already sleeping.

Xiaoxue nodded and walked out with her.

"Sister-in-law, what happened?" Xiaoxue asked until she walked outside the yard.

"That's right," the girl of Luo thought for a moment, "Do you still remember 'Hei Water City'?"

Xiaoxue nodded.

"There has been a plague recently. I want you to go with me to see the situation."

"Plague? Is it the Khitans who caused it again?"

"It shouldn't be. I've seen the description on the letter sent by the doctors there, which should be 'scine'."

"'Acne'?" Xiaoxue was shocked. Is it smallpox? This disease is extremely contagious and has a very high mortality rate, which is more terrible than the plague. Even if it is cured by luck, ugly scars will be left on her face, which may even cause complications, resulting in lifelong disability.

In Europe in the 18th century, the death toll was as high as more than 150 million due to smallpox!

The Chinese invented the vaccination technology in the second half of the 16th century and promoted it to the whole country in the 17th century. The technology was also quite perfect. It was introduced to Britain in the 18th century and was spread in Britain for 40 years. At the same time, Edward Jenner (1749~1823), the discoverer of the vaccination vaccine for smallpox prevention, was born.

In 1796, Jenner conducted an experiment on a girl who had cowpox because of it. Two years later, Jenner repeated the experiment and achieved success. Then he published a research report and announced to the world that smallpox can be conquered.

In the 1950s, the World Health Organization launched a final global battle against smallpox. After that, the World Health Organization declared that the smallpox virus had become extinct in 1980. Then, most countries in the world stopped the production of smallpox vaccines, and only a few countries had reserved a small amount of vaccines. By the 21st century, only a few laboratories designated by the World Health Organization still preserve small amounts of vaccines.

Therefore, the disease of "smallopsis" has been extinct in the 21st century, but in this era, it was the most rampant period.

"Okay, we'll set out tomorrow." Xiaoxue nodded.
