When he saw the symptoms of the deceased, Zhang Ran was already more than eighty percent sure with his rich theoretical knowledge, which was some kind of plague.

And when the five direct contacts developed erythema and even vomited one after another, Zhang Ran was 100% sure that a serious plague had crept in......

After receiving the county order about the identity verification of the two deceased, proving that the two were not from the county, only a pillar of incense had passed, and the five contacts unconsciously began to scratch everywhere, and by the time they reacted that something was wrong, their bodies were already covered with large and small red spots!

"Divine doctor, help!"

The five dogs were frightened, and while resisting the urge to scratch the itch, they begged at Zhang Ran.

Zhang Ran did not take immediate action for treatment, but began to record something on paper, and the county lieutenant took a closer look:

[Unknown epidemic disease: symptom 1, erythema all over the body, the patient will have a strong itching sensation, since contact with the source of infection, this symptom will be shown within six hours, and the symptoms of the five samples are consistent with the onset time. 】

This is......

The county lieutenant looked at Zhang Ran, who was concentrating on the record, in surprise.

"Sure enough, it's a professional miracle doctor!"

……

Time continued to pass, and Zhang Ran was surrounded by soldiers from afar, observing the follow-up symptoms of several people while making detailed records of this unknown plague, which were important information for dealing with the plague and screening infected people in the future.

The county lieutenant stayed here only for a while, and then organized other soldiers who were not present to start patrolling the city.

This is done on the one hand to prohibit the movement of people, and on the other hand, to check whether there are any other infected people in the city, and the testing standard is the "erythema" symptoms recorded by Zhang Ran......

On Zhang Ran's side, after the five of them had already developed erythema, they then had symptoms such as vomiting, dizziness, and fever, and finally fell into an unconscious coma within three hours!

"It's almost, looking at the symptoms of the two dead before, they have basically completely appeared on these five people, and if they continue, I'm afraid they will die!"

When Zhang Ran recorded this, he decisively prescribed a prescription, and he already had some clue about this plague.

"Come on, help me buy medicine and catch medicine according to the prescription."

Zhang Ran's fame was very useful, and as soon as he finished speaking, there were immediately people who were surrounded along with him rushing to help him run errands.

And the owner of the pharmacy next door was also very acquainted, not only confiscated the money for the medicine, but even actively provided decoction tools and fuel.

After all, now is the fatal moment, and everyone is counting on Divine Doctor Zhang to have a way to cure the plague......

So, the medicine was quickly fried and fed to the five people, and when they had taken the medicine, everyone waited for them to wake up.

The image that Zhang Ran left in the hearts of everyone is that he is a miracle doctor who cures all diseases and is omnipotent both inside and outside, and he has never missed a beat, everyone believes that this plague should also be cured!

However, what is desperate is that after waiting for two hours and even getting dark, the five people who took the medicine still did not wake up, and even the most obvious erythema showed no signs of disappearing:

Doctor Zhang is not omnipotent......

"Fortunately, the fever has subsided."

Zhang Ran carefully checked for a long time, and finally determined that the fever symptoms of the five people were slowly disappearing, and the other symptoms were temporarily powerless for him.

But as long as the fever subsides, the lives of these five people will be saved for the time being.

Of course, Zhang Ran also knew the despair of everyone, but he didn't have a good way, this was not a conventional disease, but an unheard of plague infectious disease, where could he find that kind of medicine to get rid of the disease!

Not to mention this era of poor conditions, it is the era of extremely advanced medical technology in the previous life, and in the face of such a terrible thing as the plague, the first choice of response is not treatment, but prevention.

Developing a vaccine as soon as possible to reduce the possibility of large-scale transmission is the best way to deal with the plague!

And now, no matter how powerful Zhang Ran's medical skills are, it is impossible to rub out vaccines and special drugs with his bare hands......

"Failed?"

Zhang Ran looked at the unconscious five, and then at the disappointed people in the distance, and he could clearly feel that an atmosphere of distrust, panic, and despair pervaded the room.

But what can he do?

For the first time, Zhang Ran felt that he had deficiencies in medical skills:

"With my medical skills, it is difficult to have a good effect on the plague with conventional means."

Medical skills in the ordinary sense are useless at this time, and if he wants to be effective urgently, Zhang Ran has no choice but to think about the means of dealing with it in terms of extraordinary strength.

"If you use the Danshu, you can refine an effective pill, but after all, the Dan material is precious, and if the plague breaks out in the future, it will not be popularized at all, but it will cause greater trouble because of the uneven distribution."

"Besides, I don't have any pill materials in my hands, so it's not realistic to alchemy to save people."

Dan Dao is not good, Zhang Ran turned his attention to the cultivation system such as qi and blood:

"Qi and blood exercises can only ensure one's own health, and they can't save others, and the imperial court strictly prohibits the practice from flowing into the people, I can't teach it if I want to, and even if you let everyone practice qi and blood now, when the effect is out, it's too late, right?"

"Qi refiners are too, they can't be popularized at all, and divine cultivators ......"

Zhang Ran suddenly thought of something:

Seminary?

"Spell!"

Although I don't know if the imperial court has a spell to treat the plague, Zhang Ran has a suitable spell in his own hand.

【Clear Plague Runic Water】!

It is derived from the world of the Romance of the Three Kingdoms and is one of the spells recorded in the "Taiping Technique".

Putting aside Zhang Jiao's Yellow Turban Uprising, when the people were struggling in the late Eastern Han Dynasty, Zhang Jiao and his disciples really used spells to save many people!

Relying on the spells on the "Taiping Technique", Zhang Jiao successfully formed a huge force of Taiping Dao, and finally launched the Yellow Turban Uprising with the slogan "The sky is dead, the yellow sky should stand......

Of course, Zhang Ran didn't want to learn from Zhang Jiao to rebel, firstly, this Dayue court is like the sun, there is no danger of destroying the country, and secondly, this court is not a mortal empire like the Eastern Han Dynasty, but a transcendent empire where the monarchs and ministers of the Manchu Dynasty are all powerful monks.

With Zhang Ran's current three-legged cat kung fu, he will take his head to revolt!

Zhang Ran just wanted to use this [Qingwen Rune Water] to try to save people's lives, but neither the rune water nor spells could be used directly in front of others, so ......

Do what you think.

Zhang Ran advanced to the medical hall, then walked into the inner room to find the pen and paper, taking advantage of this opportunity that no one dared to come in and disturb him, he dipped the ink in one hand to hold the pen, and held the white paper with the other, and silently launched the [Qingwen Fu Water].

Silently, Zhang Ran's mind was heavy, and he instantly felt that his spiritual power had been pumped by at least a small half!

"That's too expensive, isn't it?"

Zhang Ran was shocked, fortunately, there was a mysterious vitality to replenish his spirit immediately, otherwise he would be able to directly rectify his difficulties this time.

But after consumption, an indescribable power also gathered on the nib, Zhang Ran hurriedly seized the time, drew on the paper that even he couldn't understand the "ghost drawing talisman", and after drawing a full ten in a row, the mysterious power of the nib was exhausted.

"Appeal ......"

With a long sigh of relief, Zhang Ran put down the brush and picked up the ten drawn rune papers to look at them carefully:

The paper is ordinary white paper, the pen is an ordinary brush, and the ink is an ordinary ingot ink, and there is neither yellow paper cinnabar, nor the imperial pen Zhu Pi.

But it is this white paper ink talisman that has no sense of mystery, but it is the "Qingwen talisman" that condenses the spell!

"Next, it's a talisman to put into the water and feed it to them to try the effect......

With a nervous heart, Zhang Ran took five of the rune papers out of the inner room, and used the five bowls that had fed medicine to several people before, first put the rune papers into the bowls one by one, and then poured water into them in turn.

A magical scene appeared, the rune paper melted when it saw water, and Qing Shui looked still clear water!

"Master, what are you doing?"

The apprentices who were arranged to be isolated and observed in the medical hall were waiting for the results with peace of mind, and they couldn't help but be curious when they saw what Zhang Ran was mysteriously doing in the bowl.

"It's nothing, you can wait with peace of mind, if there is anything abnormal, the teacher will definitely cure you!"

Zhang Ran smiled at them, and with these confident words, the disciples, who were still a little afraid of the plague in their hearts, quietly calmed down.

Zhang Ran picked up the bowl, turned around and walked out, leaving only a tall back for the apprentices.

Several people looked at each other for a moment, and they all silently swore in their hearts:

"Master's grace, disciples will never forget ......"
