But Phil didn't come to Johns to eat or drink.

She knew that John knew about the disease in the South before she did, and wanted to see how he arranged for the town of Raya to be prepared.

After a few exchanges, I learned.

John had already arranged for the magistrate to issue an order, and now the guards at the town gates on both sides of the town of Raya were on standby, and those who came in had to be examined, and those who had ulcers or black lumps were not allowed to enter the city.

Raya Town had already communicated with the other lord castles around him, and they had all agreed to deal with this matter in this way.

Fei'er felt that this arrangement was a little uninteresting, but with the news she got so far, she didn't know how to arrange it better.

She turned her head to look at Dr. Pock: "Mr. Pock, since you have sent the south, you should know that the southern people of the kingdom are suffering from a terrible disease, I don't know what you think about this. ”

Upon hearing this, Polk smiled calmly, "I talked to Master John about this matter when Miss Raya was still in the future. ”

"Mr. Polk is very erudite and astonishingly learned." Johnson laughed and cheered.

"What do you mean, Mr. Polk knows what caused the disease?" Phil became interested.

"Now everyone thinks that this sudden illness is God's punishment for the people, and that those who get sick are guilty." Pok said slowly.

Of course, this explanation does not make sense in Fei'er, she does not believe in God at all, and God's punishment is even more ridiculous.

If Pock really wanted to say that the disease was caused by God, she would leave this place later.

"But it's not."

"This disease is collectively known as the Black Death among our Southern physicians, and I happen to have studied it with a friend."

"As far as I know, there will be ulcers on the patient's body, there will be large or small lumps, and the lumps will have blackened blood, and then the body of the patient will be blackened after death, so we call this disease the Black Death. So Master Johns, Miss Raya, you must be aware of patients with similar symptoms in Raya Town. ”

Fei'er couldn't help but ask: "Then what is the cause of this disease?" ”

Polk coughed lightly, took a sip of his drink and stood up, he enjoyed the two nobles looking at him with inquisitive expressions, he said confidently.

"The Black Death was not God's punishment, it began on March 20, 1345."

Phil couldn't help but be surprised to hear Pock say such a precise date so confidently.

"When I was studying the Black Death, I discovered that on that day, Saturn, Jupiter, and Mars coincided at an angle of 40° to Aquarius."

"Saturn symbolizes heat and humidity, it produces wind and steam, while Mars represents dryness and scorching heat."

"When Saturn and Mars meet, it ignites Jupiter's vapor and causes lightning, and the miasma produced by lightning infects humans."

"That's where the Black Death came from, so it's not God's punishment."

As soon as the words fell, Johns applauded, and even Fei'er showed a look of sudden realization and couldn't help nodding.

If Xu Siling heard Boke's words here, he was afraid that he would not have the idea of slapping him to death with a brick.

But it's no wonder that Phil believed it, but Pock's theory was very well-founded, and even for a long time, all doctors in Europe believed that the Black Death came from this way.

Because today's European physicians still follow the medical theory of ancient Greece, that is, the doctrine of four humors, which is privately called the theory of four fluids.

To put it simply, the world is made up of four elements: earth, water, fire, and air.

And the human body also has these four bodily fluids corresponding to it.

The mucus produced by the lungs represents water, the blood produced by the liver represents qi, the black bile produced by the spleen represents earth, and the yellow bile produced by the gallbladder represents fire.

The four elements, in turn, represent dryness, humidity, coldness, and heat.

Anyway, later, the famous Roman doctor Galen carried forward this medical theory, and combined the theory of the four humors with astrology, so these bodily fluids and colors are related to the change of seasons, age, and temperament, and it became Galen's "Temperament Theory".

Galen's research had a profound impact on European medicine.

It was also because of "Temperament Theory" that astrology was one of the compulsory courses for physicians at that time, if you don't know astrology and can't look at the stars, you are not worthy of saying that you are a doctor.

John didn't seem to understand, anyway, seeing that Polk was right, and his expression was so confident, he naturally believed it.

And Fei Er is full of books, and books on medical theories and astrological theories are naturally involved.

Naturally, he was able to accept the research theory proposed by Bock, and believed his words.

At least what Polk said got rid of God, and Phil was okay with it.

It's no wonder that Fei'er is stupid, it's just that the background hurts people.

"So Mr. Pock, this disease is still caused by miasma and the decaying bodily fluids of the human body?"

"Miss Raya is very knowledgeable, she is. Including several plague diseases that have occurred in the past, they have also been produced because of these. ”

Fei'er finally realized, and her heart accepted Xu Siling's prediction of the outbreak of the disease.

Although she still didn't understand why Xu Siling was able to prepare drugs for the so-called Black Death in advance, she must know that the doctors in the south were helpless against this disease, otherwise this Pok would not have taken refuge and fled here.

But at least he can accept Xu Siling's ability to predict diseases.

People can predict the date of the outbreak of the disease by looking at the stars, and Xu Siling, the executioner who is so optimistic about himself, believes that his ability to look at the stars is no worse than these doctors, right?

At this time, John asked, "How can this Black Death be treated and prevented?" I hope Mr. Polk doesn't hide it, as long as you are willing to say it, I will give you a lot of benefits! ”

Phil didn't have much confidence in this, otherwise Polk wouldn't have fled here, but he still pricked up his ears to listen.

"In terms of prevention, I still have a lot of experience." Hearing that there was a reward, Pork was happier in his heart, and the confidence on his face was stronger.

"First of all, try not to open the windows and doors in the south to prevent the humid air from the south. Then burn some scented wood in the house on a regular basis these days, especially in the patient's room, which can remove the smell of putrefaction, also stop the spread of the smell of the patient's putrid body fluids, and even fumigate the patient's lungs! ”

Johns nodded, the hair on his chin poked into his neck, and he secretly thought to himself that he would have to arrange for someone to do it later.

"Sometimes it is necessary to bake more fires, and through a lot of sweating, it also helps to drain putrid body fluids."

...

Having said a lot, the summary is to take less baths, because bathing will cause the pores of the human body to open, and although putrid body fluids can flow out, it is also easier to let the smell of putrefaction in.

Then exercise less, breathing faster after exercise will also speed up the intake of putrid odors.

It's a pity that Xu Siling is not here, otherwise the mace in his hand must have had a close contact with Pock's mouth.
