"Won't the wound get worse that way?" Guan Ping asked.

"Depending on the situation, if it is autumn or winter, the wound is not easy to worsen. In spring and summer, the wound is prone to worsening. Qian Gui replied.

"Why did the wound get worse?" Guan Ping asked again.

"Invasion of foreign evil." The money is still the same answer.

"What is an external evil?" Guan Ping asked again.

"Wind, cold, heat, dampness, dryness, fire, plague." Qian Gui was really confused, but he still answered the question fluently.

Guan Ping nodded, this is actually the basis of medical skills, Qian Gui is a doctor with superb medical skills, so he naturally answers this fluently. Guan Ping asked, but he didn't ask.

Asking is not for the sake of understanding medical skills, asking is just an introduction.

"I've recently gained a little bit of medical knowledge, and I don't know if it's right or wrong. Please also ask for advice. Guan Ping bowed and saluted, very solemn.

"Captain, please." The status of the doctor is higher, although Guan Ping bowed and saluted, but Qian Gui was not honestly afraid, but said seriously.

"Come on, go get a bowl of unboiled water." The Ding brothers at the door, Ding Feng promised to go down. Not long after, Ding Feng took a bowl of water and put it on the table in front of Qian Gui.

The water is well water, and it is fairly clear.

"I see that there are insects in this water, what do you think, sir?"

Guan Ping said with a smile.

"Huh?" The first to react was Ding Feng, he lowered his head with a probe to his brain, where are the worms?

Is the captain dazzled?

Qian Gui was also stunned, and he also glanced down to make sure there were no bugs.

But Qian Gui frowned, he didn't think that Guan Ping's eyes were spent, and the words that Guan Ping said before seemed to have deep meaning?

Qian Gui then looked up at Guan Ping and waited for the following.

"There is a worm in this heaven and earth that we cannot see with our eyes. There are countless bugs in this bowl of water. Guan Ping said.

"I don't believe it!" Ding Feng blurted out his debut.

Then he smiled brightly and bowed down.

"How can it be proven?" Qian Gui frowned and asked.

"Yo-heh." Guan Ping raised his eyebrows, and this question hit the nail on the head.

As the saying goes, practice is the only criterion for testing truth.

"There is no direct proof of the existence of bugs at the moment, but it can be proved from the side. For example, unboiled water may cause diarrhea, but drinking boiled water will definitely not cause diarrhea. This is because the boiling water kills the bugs. On the contrary, if the water is not boiled, the insects will eat it, so they will have diarrhea. Guan Ping said.

Qian Gui's brows were still tightly locked, and he shook his head and said: "Drinking boiled water will not cause diarrhea, and this kind of saying is indeed circulating at present." But it's not enough to prove that there are invisible bugs in a bowl of water. ”

Guan Ping nodded, this is a hard injury, and it is difficult to prove the existence of bacteria without a microscope.

However, the reason why Guan Ping said so much today is not a problem of a bowl of water.

Just an introduction.

"I can't prove the existence of invisible bugs, but I think they do, and it's not just a matter of having diarrhea after drinking unboiled water. The soldiers were wounded on the battlefield, and the people were bruised and bleeding, and the reason why the wounds worsened was because of the effect of these insects, which could also be regarded as an invasion of foreign evils. I think that the essence of wine can kill these bacteria, and washing the wound with alcohol, then applying medicine, and then tying it with a clean cloth will greatly reduce the deterioration of the wound. By the way, the reason why wounds are more likely to worsen in summer is because summer is the time when there are the most bugs. ”

Guan Ping said.

"The essence of wine? Unheard. Qian Gui's brows were tightly locked, and his brows had not been opened today.

Guan Ping smiled and took out the alcohol that had been prepared a long time ago.

"This is it." Guan Ping patted the small wine jar, and then said to Qian Gui: "Now is summer, the time when the wound is most likely to worsen. Try to find a few injured tun people, half of them wash their wounds with alcohol, and half of them wash their wounds with water, and see whose wounds heal quickly. ”

Qian Gui will be skeptical, but as Guan Ping said, Guan Ping can't prove the existence of insects, and Qian Gui can't prove that insects don't exist.

Do bugs exist?

Is alcohol useful?

Is the wound getting worse because of bugs?

I had no choice but to experiment.

It is currently peacetime, and there are no wounded soldiers in the Captain's Department of Diannong, but there are really a few unlucky ones.

Because of their bare feet, the two tun people were scratched by sharp stones, one fell, touched the stone, and a hole opened on his forehead, and his appearance was broken.

There were also a number of injuries for various reasons, eight people in all.

In fact, these are all minor injuries, and most people will not bother the military doctors, unless the wound worsens, it can usually heal on its own.

Although the ancients had poor medical conditions, their physical fitness was first-class and their resistance was very strong.

These wounded people were found out, and they were very puzzled, but when they heard about some treatments, they were still very happy, and they were all very cooperative.

Then Qian Gui followed Guan Ping's instructions, and the four of them cleaned the wound with alcohol, applied medicine, and tied it up.

The four people cleaned it with water, applied the medicine, and tied it up.

Because it was summer, the wound infection was very fast, and the next day, one of the four wounded who washed the wound with clean water deteriorated, and it was rare to get better.

There were no problems with the others, none of them deteriorated.

This proves that the quality of the ancients is really strong, Guan Ping has seen it, the so-called clear water, in fact, is slightly turbid.

Wash the wound with this kind of water, but it is not infected?

And in this way, the advantages of alcohol to clean the wound cannot be demonstrated.

Eight people, only one was infected.

So Guan Ping conducted the second, third, and fourth experiments, and used fifty or sixty people to prove it.

Cleaning a wound with alcohol is less likely to worsen the infection than washing it with water.

Because the Han people have good resistance, even if they wash the wound with water, they are not easy to get infected.

Washing the wound with alcohol reduces the chance of infection by about 20 percent compared to cleaning the wound with water.

It looks inconspicuous, but if in a battle of 100,000 people, tens of thousands of soldiers were wounded, then there are more soldiers who can be rescued, which is a major breakthrough.

Guan Ping has long known about the results of this experiment, the joy has passed, and the rest is calm.

But Qian Gui, the military doctor who helped Guan Ping complete this experiment, was as happy as if he were a child.

This is not just a matter of saving soldiers and human lives, it is a medical breakthrough.

Before that, Qian Gui will be skeptical about Guan Ping's theoretical knowledge, is there really a bug in this world that cannot be seen by the naked eye?

Got that little bug?

Guan Ping told him that there was indeed such a bug, and it was because of this bug that the wound would worsen after being injured.

Alcohol can kill these bugs.

Although it still can't prove the existence of insects, it has an effect, so Qian Gui believes in the theory put forward by Guan Ping.

There are bugs that are invisible to the naked eye.

So Guan Ping's leisurely days are gone, and almost every day there is an old military doctor named Qian Gui, who comes to ask for advice, with a very low posture, almost holding a disciple salute.

"Sir, don't be like this, I just heard a few Hu merchants from the Western Regions talk about this. I don't know how to heal at all, and I've already told my husband everything I know. Guan Ping said helplessly.

put forward this bacterial theory, Guan Ping has no regrets.

After all, there are only benefits to this, and there is no harm.

The only thing I regret a little is that I chose Qian Gui to be such a person with a strong desire for knowledge, where does Guan Ping know what medical skills?

After being chased and beaten by Qian Gui, he emptied the inventory in his stomach. For example, "If the wound is deep and does not heal on its own, it can be closed with sutures." ”

Anyway, Guan Ping is not a doctor at all, and only knows some basic medical skills.

After being chased and beaten hard for a long time, the bit of ink in his stomach has long been consumed, and his original form has been exposed.

Qian Gui didn't speak, but looked at Guan Ping with a pair of burning eyes, and the light that shot out of his eyes was "curiosity".

Qian Gui is very obsessed with many theories put forward by Guan Ping, and every time he comes to Guan Ping, he can take out a lot of good things, and he has never returned empty-handed.

Qian Gui believed what Guan Ping said, and Guan Ping's theories were all heard by the Hu people, because the Han Dynasty did not have such medical theories.

Qian Gui also believes that Guan Ping said that he has told everything he knows, but maybe there is something missing? What about omissions? What about omissions?

Anyway, every time the money comes, you can take out some new goods.

If you push the captain, you can always gain new knowledge.

But this time Guan Ping is really gone, he really emptied the inventory. So Guan Ping excused himself for urgency, and then slipped away.

Classic urine.

Qian Gui was very helpless, but he was also helpless. He's a military doctor, so he can't chase after the captain of the agricultural school, right? So, Qian Gui could only leave in a huff.

"Bacteria???? According to the Captain, bacteria can only be seen if a microscope is created? But what is a microscope??? What is glass??? ”

Qian Gui is like a child with a strong thirst for knowledge, but the more he understands, the more problems he has, and he is deeply trapped in this strange circle and cannot extricate himself.

"I will study hard, and according to the words of the captain, practice is the only criterion for testing the truth. I want to work hard to improve my medical skills and then benefit the world. ”

Qian Gui's face bloomed with a grand light.

As the saying goes, if it is not a good look, it is a good doctor.

There are many people from poor families who cannot study literature and study medicine instead. Qian Gui is from a poor family, and his family has been solid since he was a child, and he can't learn literature, but he is good at studying medicine.

Literati naturally have a romantic feeling.

If it is not a good look, it is a good doctor. Good medicine can also benefit the people of the world, which is very great.

Guan Ping met Qian Gui and taught Qian Gui this modern medical foundation, but he was also in the right place and chose the right person.

A good seed also needs good soil, proper water, and experienced farmers to grow good crops.

Guan Ping provided Qian Gui with seeds, and it is also soil and water, as long as Qian Gui dares to study medical skills, Guan Ping will support him.

But whether the seeds can grow well or not depends on the farmer.

Qian Gui is a good farmer.

This incident happened on an ordinary summer, and the inconspicuous Xinnodian Agricultural School Captain's Department, but it had a far-reaching impact and a long way to go.
