Reborn and married to a stupid scholar, she has a prosperous husband and multiple children

All that's left is to wait for the cow to become infected and pus to flow out. This process takes about 7-10 days.

The pus discharged from the cow is the cowpox vaccine, which contains the virus, but is much less toxic.

As long as this very weak cowpox vaccine is implanted in the human body, the body will produce antibodies, and when the plague breaks out, there will be no fear of infection.

Seven days later, pustules finally flowed out from the cattle, and Lin Shuangshuang obtained the cowpox vaccine from the cattle.

Then he burned all his clothes and utensils before leaving the yard.

After leaving the yard, she didn't rush to get close to the crowd. Instead, she used lime and alcohol to thoroughly disinfect the inside and outside of the yard.

Finally, another fire burned the house and the dying cow.

Fortunately, the eldest brother had already bought the yard in advance, otherwise she would have had to worry about burning down the house.

"Quickly put out the fire, there's a fire in Jinzhong's yard."

"Quickly put out the fire...quickly put out the fire..."

When the villagers saw the fire in the yard of the big house, they came over with buckets and wooden basins to put out the fire.

Everyone in the Gu family's old house was also alarmed, and Yang's legs were so frightened that they became weak.

Her son and daughter-in-law are still in the yard, so nothing happens.

When the Gu family ran up and down, they found Lin Shuangshuang and Gu Hanzhou standing at the door, and they breathed a sigh of relief.

When Yang saw Lin Shuangshuang blocking those who were putting out the fire, she stepped forward with lingering fear: "Shuang'er, what happened? Why did it catch on fire?"

"I put it on purpose."

"What, you put it on purpose?"

"Why did you set the fire?"

Now not only Yang was confused, but also the villagers who were putting out the fire were confused.

"Folks, stay back, be careful of the fire spreading and injuring innocent people."

"I'll explain it after the fire is out."

"Second brother, take someone to guard the house. Don't let the fire burn into the neighbor's house."

Gu Jinguo agreed without thinking.

The fire attracted almost all the villagers.

Everyone is talking a lot, wondering why Lin Shuangshuang deliberately set the fire?

But what was burning was the Gu family's big house, so no one else was in a hurry, so they were certainly not in a hurry, they just wanted to watch the excitement.

"No, this is not Gu Jinzhong's house. He just rented it for a period of time."

"What Lin Shuangshuang burned was someone else's house. How should we explain it to the owner?"

"Who knows, let's see what she says later."

The village chief heard the commotion and ran over to ask what was going on.

"Village chief, let's go home and talk."

"Second brother, no one is allowed to come near until the fire is out."

Gu Jinguo nodded, he knew the seriousness of the matter better than those who were watching the excitement.

Although it was unclear what Lin Shuangshuang did inside, based on what she said before, we could guess that the things in the yard were highly toxic, so they were burned.

Village Chief Li followed Lin Shuangshuang to the Gu family's old house.

Lin Shuangshuang said: "Village Chief, you may feel scared by what I am going to say next, but you must not get excited, because you will be in charge of the overall situation next."

When Village Chief Li, Yang and others heard what Lin Shuangshuang said, their breathing became rapid due to nervousness.

"You tell me, I've lived a lifetime and seen a lot of strong winds and waves. I can withstand it."

Lin Shuangshuang said with a serious face: "A plague is about to break out."

"What?"

Everyone was shocked. They all expected to hear something terrible next, but they didn't expect it to be this kind of thing.

plague!

What a terrible word. This is much more terrible than any drought or flood.

Every time a plague breaks out, more than half of the country's population will be lost, and some small countries will even be wiped out directly.

Therefore, everyone present knew how terrible the plague was.

The village chief calmed down first, but his voice still trembled: "Is this news true?"

"I saw it with my own eyes."

"A while ago, my husband and I went out for more than 20 days. In fact, we went to Nanshi County."

"Because this flood first broke out from Nanshi County, and it took a month for the water to break out here."

"The book says that after a major disaster there will be a major epidemic. This is the experience summed up by our ancestors over thousands of years."

"What's more, this flood affected a wide range and lasted for a long time. Countless people, livestock and poultry died in the flood."

"If those human and animal corpses are soaked in water for a long time and cannot be salvaged and buried in time, a large number of viruses and bacteria will breed."

"The virus-infected water flows into rivers and lakes, and people who drink it will get sick, and then spread the disease over a large area, forming a plague."

"Viruses and bacteria?" Everyone was puzzled.

Lin Shuangshuang explained: "It is an invisible and intangible poison that can spread through the air."

"Air is the gas we breathe."

"Those who are sick can spread the virus in their bodies into the air through sneezing, coughing, and spitting."

"The air blown by the wind will carry the virus to distant places. This is how the plague spreads."

Lin Shuangshuang spoke in an easy-to-understand manner, and everyone barely understood.

"Then how are you sure there will be plague in Nanshi County?"

Lin Shuangshuang shook his head: "I'm not sure. I was just worried that a plague would break out there based on my ancestors' experience, so I went to check."

"It turns out I guessed it right."

"When I arrived in the city, I saw a lot of wailing, and many people were dead on the roadside."

"I felt the pulse of one of them, and the symptoms were clearly smallpox."

"What? Smallpox?"

Everyone's expressions changed again. Smallpox is the most feared of all plagues, and it is also the one that spreads the fastest.

Some plagues only kill some livestock and poultry, but not people.

There are also some plagues that only kill some old people and children, leaving young adults alone.

Smallpox, on the other hand, is a common disease, and whoever gets it will die, regardless of whether they are old, children or young people.

"This...how can this be done..."

"Why doesn't God have an eye? Woohoo... there was a flood just now, and here comes the plague..."

"This is God's acceptance..."

Yang couldn't help crying, and Wang also quietly wiped her tears.

It doesn't matter if they are dead, she mainly feels sorry for her children, they are still so young...

Lin Shuangshuang quickly comforted her: "Mom, don't be afraid, I have developed a medicine to prevent the plague."

"Otherwise, what would I be doing in Brother's yard?"

Yang stopped crying at that time: "What, you... have you developed a medicine to prevent the plague?"

"Is this...serious?"

Even Village Chief Li was shaking with excitement. If this were true, then the Gu family's wife would be the world's savior.

"Of course it's true. How could I joke about something like this?"

"So we need the help of the village chief to get the whole village vaccinated against the plague."

"What is a vaccine?"

"It's the name of the medicine to prevent the plague." Lin Shuangshuang explained briefly.

The village chief happily agreed: "This is natural. How can I stop such a good thing?"

"I will do whatever you tell me to do."

Lin Shuangshuang hesitated and said: "The method is very simple, but it is a little difficult to convince everyone to take the vaccine."

"Why?"
