Such a plague has happened more than once, and when Liu Zheng first met Zhang Zhongjing, Zhang Zhongjing was near Runan, specializing in investigating the plague that occurred in Runan.

In ancient times, it was called typhoid fever.

According to Liu Zheng's impression, during the Three Kingdoms period, there was indeed a plague that shocked the whole country, and the impact was very profound.

That plague caused at least 10 million deaths and injuries in the Han Dynasty, and even the famous seven sons of Jian'an at that time, four of them died in the plague.

As for the plague prevalent in small areas, it is even more numerous, and the reason why Zhang Zhongjing, who is known as the saint of medicine, is determined to study medicine is also because a plague that occurred in Nanyang killed and injured more than half of Zhang Zhongjing's clan, and two-thirds of the family's population died at the hands of the plague.

Even Zhang Duyu's biological parents died in this plague, and after witnessing the tragedy of the plague epidemic in the world, Zhang Zhongjing was determined to challenge typhoid fever and wanted to be a doctor who saved the suffering of the world.

Although Zhang Zhongjing later lived in Jiaozhou after following Liu Zheng, and there were few plagues in Jiaozhou, it did not mean that Zhang Zhongjing had given up the study of plagues.

Not only did he not give up, but he became obsessed, under Liu Zheng, Zhang Zhongjing has cultivated a lot of disciples these days, and the best of them is Huang Zhong's son Huang Xu.

After having these disciples, the medical problems in Liu Zheng's military camp were rarely worried about by Zhang Zhongjing, so Zhang Zhongjing had a lot of time to study the plague.

In addition, after the Jiaozhou region and Yangzhou region were taken by Liu Zheng, there were more medicinal materials for Zhang Zhongjing to choose from, which made Zhang Zhongjing's research on the plague more sophisticated.

After Liu Zheng encountered the plague, the first thing that came to his mind was Zhang Zhongjing, because Liu Zheng knew that only Zhang Zhongjing could solve this kind of thing at the moment.

After Liu Zheng got married, Zhang Zhongjing also moved from Jiaozhou to Liu Zheng's mansion in Yangzhou, and lived with Zhang Duyu, first, to take care of Zhang Duyu, and secondly, Liu Zheng's mansion was the safest place to protect Zhang Zhongjing.

Liu Zheng hurriedly returned to his mansion, and he didn't even have time to take a look at his newborn son, so he found Zhang Zhongjing directly.

Zhang Zhongjing planted some medicinal materials he had studied in the backyard, and Liu Zheng rushed in and shouted at Zhang Zhongjing.

"Mr. Zhongjing is not good! Oh no! ”

Zhang Zhongjing got up from the ground, and when he saw Liu Zheng's panicked appearance, he also frowned and immediately asked.

"What's wrong?"

When encountering other things, maybe Liu Zheng wouldn't be so nervous, but the plague was such a thing, so Liu Zheng couldn't help but joke. Even if he has always been calm and calm, at this moment, he is a little anxious.

"Plague, there was a plague in Qingzhou, which caused it to spread to the soldiers and horses under my command, and now there are hundreds of sick people in the army, I think only Mr. Zhongjing can you have a way."

As soon as Zhang Zhongjing heard the word plague, his face immediately sank, and he seemed to realize the seriousness of the matter, but after all, Zhang Zhongjing had some research on this thing, and he didn't have Liu Zheng's panicked feeling, so he immediately comforted Liu Zheng.

"Don't worry, I'll go over and take a look."

Zhang Zhongjing turned his head and entered the house, then put a box on his back, pulled Liu Zheng and began to walk towards the barracks.

On the way to the barracks, Zhang Zhongjing had already begun to ask Liu Zheng about some details, such as the symptoms of the plague and what specific manifestations there were, and after learning about some of these conditions, Zhang Zhongjing began to instruct Liu Zheng to carry out some methods to defend against the plague.

First of all, the first point is to set up border quarantine stations, and cities and towns can test each other to prevent the spread of the virus.

The second point is to control the source of the disease, so that the sick people can be isolated in a centralized manner, so that it is convenient to observe.

The third point is to set up special medical care to treat these sick people.

Fourth, the sick are exempted from all kinds of taxes.

Fifth, clean up the environment and improve the living conditions of the sick, especially paying attention to drinking water, which was mostly transmitted by water sources in ancient times.

Zhang Zhongjing's description made Liu Zheng immediately nod his head in agreement and began to instruct.

It didn't take long for Zhang Zhongjing to come to Liu Zheng's barracks, and in the barracks, there were already some patients in the barracks, but these people didn't have much means for the plague, and they had no experience, so they were basically helpless for such a disease, so they could only wait for a famous doctor like Zhang Zhongjing to come and see.

Zhang Zhongjing's expression was gloomy, and he observed the bodies of the patients one by one, not directly contacting the patients, but standing one meter away from the patients, looking the patients up and down, and then asking some of the patients who were still conscious and how they felt.

After asking questions one after another, Zhang Zhongjing's gloomy face finally improved somewhat.

Withdrawing from the barracks, Liu Zheng hurriedly stepped forward to ask Zhang Zhongjing.

"Mr. Zhongjing, how is it?"

Zhang Zhongjing exhaled, and then said, "Fortunately, this plague is not serious. ”

The plague does not just refer to a disease, but a general term for a virulent infectious disease, what the specific disease is, no one can say clearly, after all, the current medicine is not as advanced as that of later generations, and Liu Zheng did not carefully ask Zhang Zhongjing what the plague was specifically produced.

Those things, even if Zhang Zhongjing told him for three days and three nights, Liu Zheng couldn't figure it out, all Liu Zheng cared about was whether Zhang Zhongjing could treat the disease.

"It's not serious, so Mr. Zhongjing means it can be treated?"

"It's hard to say whether it can be treated, I'll go and mix a dose of medicine first, try it, although it can't be treated, but it should be able to curb the spread of this plague."

Zhang Zhongjing didn't say anything to Liu Zheng, the most important thing now is that Liu Zheng didn't dare to disturb Zhang Zhongjing more in the treatment of this plague.

In addition, it is useless for him to stay here, and more importantly, his subordinates are worried that Liu Zheng will also contract this disease, and persuade Liu Zheng to leave here as soon as possible.

Liu Zheng knew his ability, and staying couldn't help much, so he could only leave first.

After returning to the mansion, Zhang Duyu, Cai Yao and others came over to greet them in a hurry, and they also heard some news from the subordinates, and they were all looking forward to it at the door at this time, not knowing what happened.

When Liu Zheng came back, he was still followed by a Zhang Ning.

However, because he had something important to find Zhang Zhongjing before, Liu Zheng did not introduce Zhang Ning to Cai Yao and Zhang Duyu, and now when he came back, Zhang Ning had already met Cai Yao and Zhang Duyu, and they knew each other, so Liu Zheng was omitted to introduce them again.

Actually, Cai Yao and Zhang Duyu had also met Zhang Ning before.

also knew that Zhang Ning and Liu Zheng had a trace of inexplicable and unclear relationship.

However, everyone knows that there will be no complaints about this.
