In the ninth year of Jian'an, at the end of December, the year is approaching.

At this time, it was supposed to be a day for the whole Han to celebrate together. However, the current Han family is plain and wails night and night. In the past, although there were often disasters of swords, but whenever the New Year passed, the people of Dahan still did not forget the upcoming New Year. However, this year......

From the beginning of the outbreak of the plague to the present, in just a few months, the entire Han has fallen into a state of desolation. Except for Liangzhou, which is far to the west, the plague has appeared in the rest of the states and counties.

Although, after Cao De returned from Youzhou and stepped into the closing gate of Huguan, Cao De began to give various orders one after another. But the terrible stuff of the plague is always pervasive.

However, thanks to some measures taken by Cao De in time, the epidemic situation in Han China is much lighter than that of other states and counties!

And now, Cao De's biggest headache is that he needs to immediately come up with a cure for this plague. Whether it is in Cao De's previous life or in this life, whether it is a major illness or a minor illness, the most important thing is to prescribe the right medicine.

People have a cold, you give a medicine for diarrhea, what's the use of eggs. Therefore, in order to treat this plague, the first thing you need to understand is the origin of this plague and what caused it.

Since the plague came from Jiangdong this time, this distance was indeed a little far from Chang'an, and in order to prevent the plague from spreading unscrupulously to Hanzhong, Cao De also closed all the passages early. Therefore, it is impossible for Cao De to send someone to Jiangdong to investigate.

And in this way, it is undoubtedly the first major difficulty at present.

However, just as Cao De was blinded, Spicer came. Moreover, Spell brought a piece of news. This news was sent back by the Black Pearl lurking in Yangzhou before the outbreak of the plague.

This plague was brought by the Shanyue people who migrated north. Therefore, Cao De's eyes are mainly focused on the Shanyue people. And the information that Spicer brought was only two stars, but it gave Cao De a big hint.

Before the Shanyue people left the mountain, they had no food, and they had to face the encirclement and suppression of Zhou Yu's army. Therefore, many Shanyue people walked out of the mountains because they didn't even have to eat rats and corpses.

Cao De keenly discovered the words "rat" and "corpse". Cao De feels that the problem is here!

Cao De also remembered a catastrophe in the middle of the nineteenth century in Cao De's previous life, when the plague broke out in Yunnan under the rule of the Taiping Heavenly Kingdom, and due to the population movement caused by the war, the plague quickly spread to the whole world, and the death toll of the plague was 200 million! There was also the Black Death, which broke out in Europe in the thirteenth and fourteenth centuries. Among the plagues, the most terrible is the plague. Because, a large part of the transmission route of this plague is rodent-dependent transmission. And rodents are the most abundant group on Earth. Add to that the seamless envoy like a mouse......

Now Cao De couldn't help but shudder when he thought of the plague.

Up to now, not to mention the rest of the Han Dynasty, the number of people who have been infected and isolated and died in Han China alone has approached 10,000. Although 10,000 people seems to be not a lot, this is the result of Cao De's precautions in advance. What kind of losses will Liu Bei, Cao Cao and others who are not prepared in the slightest, Cao De directly dare not imagine.

By the end of December of the ninth year of Jian'an, there was a plague in the entire Han Dynasty, and the Xianbei people in Youzhou retreated to the grassland in October. But the Xianbei people did not escape the clutches of the plague.

Due to the previous Kebi can destroy farmland and return farmland for grassland, Xianbei people have no choice but to raise cattle and sheep again, but the incidence of these livestock is higher and faster than that of Xianbei people. Often, if one sheep falls in a tribe, the whole tribe begins to suffer the threat of extinction.

Cao De was not worried about the life or death of the Xianbei people at all, what Cao De was most worried about was actually Ma Chao and Zhang Liao who went deep into the grassland and the three thousand knights.

In Han China, Hua Tuo and Zhang Zhongjing led a generation of disciples to form the Plague Rescue Research Center, and when Cao De sent the message, the research center was aimed at rats. After two months of investigation and experiments, Hua Tuo and Zhang Zhongjing also proved that this was indeed caused by mice.

Previously, Cao De's Prime Minister's Palace had issued a national order. The whole of Han China entered a period of military jurisdiction. All those who do not obey the management will be killed!

Make simple masks for all. Since Cao De did not have any preparation before, Cao De did not have time to develop and produce charcoal, the best filling in the mask. Therefore, Cao De's mask is filled with cotton, and then dipped in high-purity distilled alcohol. After the mask order was issued, adults and children throughout Han China were covered with white masks on their mouths, and there was something similar to a water bladder pinned to their waists. And, most commonly, when two people need to talk when they meet, they need to sprinkle some disinfectant on the mask first.

And now the first of the national order is to hunt rats. The local government distributes specially prepared rat poison and makes simple tools such as rat traps. Moreover, all dead and captured rats need to be processed centrally.

Second, cremation is necessary for all those who die of the disease. The cremation must be supervised by the local government.

……

10 years of Jian'an, February. At this time, in Jiangdong, southeast of the Han Dynasty, after nine months of plague, the population plummeted by 30%. But the only thing that can reassure Sun Ce is that the epidemic has finally almost disappeared. But in the north, in the grasslands of Youzhou and even further north, the plague began to really threaten. The epidemic in Han China has been effectively controlled. Although people are still being sent to quarantine every day, the growth rate has indeed dropped by nearly 60%!

However, the thing that made Cao De ecstatic the most happened in Bingzhou, and it was also in the north of Bingzhou, Yanmen Pass!

When the plague began to penetrate into Han China, the army that had been gathered together was dispersed by Cao De as a unit, and Liangzhou, southern Yizhou, and the Qiang people's residences, where the epidemic was lightest, almost became Cao De's garrison location. However, Cao De still specially selected a group of brave men from the army and divided them into several branches and stationed in the north of Liangzhou and Bingzhou. They have only one mission, to dispatch as soon as news comes from the north. However, before it was their turn, the gang came back on their own!

Cao De looked at the urgent report from Yanmen Pass in his hand, and showed a relieved smile for the first time. It's back, it's finally back.

Ma Chao and Zhang Liao are back. However, the 5,000 soldiers who traveled north with Ma Chao and Zhang Liao only returned, less than 500 people.

And when Ma Chao and Zhang Liao saw Cao De, Ma Chao and Zhang Liao hugged Cao De and cried. "Prime Minister, the last general really doesn't have the face to meet the Prime Minister! If it weren't for the soldiers, the two of us would ....... ”

"Crying for what? The blood debt given to us by the Xianbei people, in the future, we will get it back. ”

"No, Prime Minister. It's like this......"

After Cao De listened to Ma Chao and Zhang Liao's narration, Cao De was also stunned, and his eyes gradually turned red. "What a great warrior!"
