"Last night, there were eighteen households in Guiyifang, and nearly 100 people continued to develop the disease. The symptoms were chills, high fever, chest pain, cough, coughing blood and phlegm... The head and neck were scrotch, pustules on the skin, and occasionally anthrax... The severely ill person was confused, delirium or coma... Starting in the afternoon, the first death occurred. The dead were covered with bleeding and cerebral all over the body, and the corpse was cyanotic and purple-black... Old Master, this is a plague! It must be a plague!"

Cha Xiaoyi stood at a downwind that was about five steps away from the carriage, reporting the situation to Tang Ning, who had never stepped out of the carriage carriage.

"The deceased was covered with bleeding and cerebral all over his body, and his body was cyanotic and purple-black..." This description attracted Tang Ning's attention. After repeating it in a low voice, he finally matched the plague that matched this characteristic from his memory: "Hell, it's the Black Death!"

The Black Death, or the plague, has been raging for at least 1,500 years in the history of the earth, and three large-scale outbreaks have occurred in the past and afterwards, especially the European outbreak that directly wiped out one-third of the continent's population! The three major outbreaks and scattered small-scale spreads have killed at least 150 million people in total!

Before Tang Ning traveled through time, the plague, a ghost thing that makes people feel terrified, is still ranked first among the Chinese Class A infectious diseases! Compared with the plague that kills people like mowing grass, it is two weak little brothers!

The problem is that Tang Ning’s understanding of the plague is basically the above. He can’t even remember whether the plague is a virus or a germ.

Ah, wait, I remembered something again!

The initial infection target of the plague is mice. The fleas that spread the plague to humans are like mice? Then after it is transmitted to humans, it seems that it can spread quickly through cough droplets or other channels?

Then... it's really gone.

"Xiaoyi, you were already cured and saved people in Guiyifang last night?"

Tang Ning looked at Cha Xiaoyi, half concerned and half alert.

If Mr. Tang had been a doctor who had studied plague before traveling through time, then he would definitely have had more than this reaction now, because the situation described by Cha Xiaoyi far exceeded the rate of infection and death of normal plague!

"That's right. I happened to stay overnight in Guiyifang yesterday." Cha Xiaoyi nodded and confirmed, and asked again: "Old Master, what is the disease of the Black Death you just mentioned?"

"You don't know about the Black Death?" Downing was surprised: "What about the plague? You should know about the plague, right?"

"I don't know..." Cha Xiaoyi showed a shameful expression when Tang Ning saw it: "Old man, can you please tell me in detail?"

"Have you been bitten by fleas? Are there any discomforts in your body now? Do you cover your mouth and nose when you come into contact with those plague patients?"

Tang Ning did not explain in detail, but asked three questions in a row.

"I carry an anti-worm sack with me, and I can't even know lice, fleas, mosquitoes..." Cha Xiaoyi responded halfway and reacted: "Old man, do you think I'm also infected with the plague?"

"Yes, I'm really worried if you're also infected with the plague."

Tang Ning did not choose to speak nonsense, but admitted it frankly. After all, this is likely to be at least one-third of the plague that died within five days after being infected!

Really, if it weren't for Cha Xiaoyi standing opposite him now, he would never have stayed here to talk to him.

"I feel that there is no abnormality in my body, and I should not have been infected with this plague." Cha Xiaoyi replied, and then continued to ask: "Old Master, saving people is like putting out a fire. Please be sure to tell me the Black Death you mentioned just now!"

Say or not?

Tang Ning hesitated for a moment, and then chose to take the risk to give Cha Xiaoyi a popular science: "Xiaoyi, I read an ancient book when I was young, and saw records of the fierce plague and Black Death in the book. I vaguely remember that this plague originated from rats, so it is also called plague, it..."

In order not to cause unnecessary trouble, Tang Ning created an ancient book for the source of plague knowledge, and then explained the relevant knowledge he knew. He focused on the transmission of plague and the protective measures that must be taken when contacting patients.

"This plague is so dangerous?"

After hearing this, Cha Xiaoyi gasped and said that the plague could be transmitted to each other through saliva droplets and contact. With the population density and sanitation in Guiyifang, one-third of the mortality rate must be reached at the upper limit!

If the control is not effective, the terrifying plague will spread to other neighbors in the city... the consequences will be unimaginable!

No wonder the old man, after discovering the situation, immediately faced a great enemy, controlled the gang circle and banned those who joined in the fun!

"Old Master, I will serve the people in Yujing City. Thank you for your great kindness!"

Cha Xiaoyi bowed to Tang Ning Yingying.

"No need to be like this, I am not as great as you think."

Tang Ning waved his hand. He did so much more importantly, just to protect himself.

Unexpectedly, after saying this, Cha Xiaoyi's gaze became more and more respectful.

Cha Xiaoyi was about to say something else, and Jingzhaoyin was under the jurisdiction of Wannian County and the county magistrate and county magistrate who were responsible for managing the south of the city came hurriedly with a large wave of yamen runners. Tang Ning, who was prepared, immediately left Cha Xiaoyi and called the two people-friendly officials onto the carriage.

After a moment, the county magistrate, whose face was so scared, was at least six feet tall but strong, and staggered off the carriage. Then the county magistrate issued an order to send the yamen runners to start their work.

Who went to collect quicklime and other anti-virus materials? Who cooperated with the Daolu Guards who arrived first to guard the front and back doors of Guiyifang. Who led a team to find cloth to make temporary masks and protective clothing in nearby markets. They inspected and arrested the residents of Guiyifang who were scattered into the market. Who went to collect coffins, who went to summon more people, who went to the Imperial Hospital to report the news, who went to the Wei Palace to report the news... The short and energetic county magistrate arranged the yamen runners in an orderly manner, and no one dared not to obey his orders.

This county magistrate has a very clear and majestic idea, and seems to be a talent who is good at doing things.

Tang Ning, who saw this scene, took out a small notebook with him to remember things with him, and dipped it in a goose feather and wrote a note on it - Yan Yannian, the commander of Wannian County.

Next, there will be nothing left.

"Let's go again."

Tang Ning touched the fur that was so good-looking in his arms and ordered.

"Master, are you going back to the royal palace?"

Dian Zaixing, who had already returned, asked while pulling the reins.

"No, go to the Daolu Department."

All of them have reached this point, and Mr. Tang would rather take a little more risk than achieve the purpose of this trip.

"Old man, why don't you go back to the house first..."

Hongluan and Qingluan, who were accompanying him, persuaded each other in unison, that the terror of the plague described by Tang Ning just now was particularly in his ears, and they were really afraid.

Unfortunately, how could Mr. Tang, who had made up his mind, be moved by this level of persuasion?

So the carriage continued to move forward.

"Old Master, in the ancient book you read, is there any medicine that can relieve this epidemic?"

Cha Xiaoyi suddenly asked loudly.

There was a sudden silence around me.

Yes, sulfonamide, streptomycin... or antibiotics such as cephalosporin should all kill plague bacteria or viruses.

But these medicines are all in the earth.

With the medical level in this world, the only reasonable and feasible anti-epidemic plan is probably to strictly guard against herd immunity.

Good luck to you.

Tang Ning sighed and closed his eyes.
