I'll hand over the system soon.

Gu Xingyun wanted to speak again, but Zhong Tang interrupted him.

"If you have anything to say, please find time to tell me later. Little girl, please tell me first what disinfection and sterilization are and what bacterial inflammation is?"

Sancho was a little surprised. She seemed to have underestimated the old man's identity.

This old man had this unceremonious attitude toward Gu Xingyun. Could it be that he was Gu Xingyun's elder?

But weren't all the Gu family killed by Emperor Li Zong, and only Gu Xingyun was left?

Sancho, who couldn't figure it out, turned his eyes and saw Ning Yuan still looking at her with eyes full of meaning. He sighed slightly. She stopped acting. She was already exposed anyway, and any acting would be just a joke.

"Let me first talk about what bacteria are. Please look at the wounds of these two wounded soldiers." Sancho turned everyone's attention to the wounds of the wounded soldiers.

"Huh? The wounded soldier's wound on the left has been ulcerated. Although the one on the right is also red and swollen, it is much better than the one on the left." Gu Anle couldn't help but answer.

She was recuperated in the Medical Valley since she was a child, and became a doctor after a long illness. In addition, she was quite interested in medicine, so she was considered a registered disciple of Zhong Tang.

Sancho glanced at Gu Anle and saw her and a man standing a little behind the old man who asked her. Their faces were respectful and polite. They must be the old man's juniors or students.

Sancho said: "Yes, and it is the bacteria I am talking about that make the difference."

Unable to explain to them what prokaryotes are, Sancho could only make an analogy: "You can understand bacteria as tiny bugs that are invisible to the naked eye. Those bugs that are visible to the naked eye are called bugs, but these invisible bugs are invisible to the naked eye." The insects are called bacteria."

"As we all know, bugs, especially the smaller bugs, like to live in groups, and the same goes for bacteria, and they not only like to live in groups, but also like to live in mixed groups. That is to say, in this wound alone, there are many kinds of Bacteria exist.”

"If it's invisible to the naked eye, how do you see it?"

It was Ning Yuan who asked this question.

Sancho almost didn't mention it in one breath, very good, so how can she explain how she knows about bacteria.

Seeing everyone looking at her, Sancho said bravely: "I saw it in an ancient book. The author of the ancient book made an instrument that can make an object very large, making it invisible to the naked eye. The bacteria can be clearly seen after being amplified by the instrument."

"Is there such a magical thing in this world that can magnify things that are invisible to the naked eye until they are clearly visible?"

Everyone was concerned about the magical instrument, but Zhong Tang was concerned about: "Does the book say how that thing was made?"

Ning Yuan is concerned about: "Where did Miss Sang get that ancient book? Can I borrow it from a certain perspective?"

Sancho shook his head lightly: "The book does not describe how to make the instrument. As for the ancient book, I have long lost it."

Sancho knew that her excuse was quite poor, but it didn't matter, they had no evidence anyway, and whether she believed it or not had no effect on her.

Seeing Ning Yuan's mouth slightly open, as if he wanted to ask something else, Sancho hurriedly said: "You have practiced medicine for many years, and you must have discovered that people with serious trauma often die of fever in the end."

Sancho's topic changed obviously, and Ning Yuan snorted but did not interrupt.

Dr. Geng responded excitedly and cooperatively: "It's very, very true. Nine out of ten of the wounded soldiers in the camp died from external evils entering their bodies."

In ancient times, people classified the causes of fever into two types, one was endogenous dampness evil, and the other was external evil entering the body. The former was a fever caused by internal causes of the body, and the latter was caused by external causes.

Common colds are caused by external evils entering the body, and fever caused by wound ulcers are also caused by external evils entering the body.

After a pause, Dr. Geng realized the connection that Sancho wanted to point out, and then said: "The wounds of the wounded soldiers who died from external evil entering the body all have serious ulcers, and even more serious ones are even rotten and festering."

Sancho nodded, "The reason why their wounds can ulcerate or even fester is because there are billions of bacteria in their wounds. These bacteria are like poisonous insects, preventing the wounds from healing and causing the wounded soldiers to have fever."

Everyone nodded thoughtfully, Zhong Tang thought carefully for a while and said: "So the disinfection and sterilization you mentioned means killing bacteria?"

Sancho: "Exactly."

"What does inflammation mean?"

"It's just another name for ulcers in that ancient book."

While everyone was still digesting what Sancho had just said, Zhong Tang had already thought of something else. He pointed to the wounded soldier on the right and asked, "Then how did you kill those bacteria?"

In fact, as the master of the Medical Valley, he had already studied the fever caused by wound ulcers when he was young.

He generally knew why wounds ulcerated, and he also knew some methods of treating ulcers, but the effects were not very obvious.

Moreover, once the injured person develops a fever, it is extremely difficult to rescue him or her.

After studying for half a lifetime, I still haven't found anything clear, but now a little girl has clarified my confusion.

Sancho was not stingy about spreading the knowledge she knew. She answered generously: "The first step in disinfection and sterilization is to keep the injured area as clean as possible."

"I just missed mentioning that bacteria are not only found in wounds. They are actually everywhere. We even inhale a lot of bacteria every time we breathe in."

Before everyone showed fear, Sancho continued: "But just as not all bugs are poisonous, not all bacteria are harmful to our bodies, and our human body itself has a certain defense mechanism, so when we breathe in, Bacteria in the body will not cause any harm to us."

"Given that bacteria are everywhere, it is conceivable that there are countless bacteria on our hands. If we directly touch the wounds of wounded soldiers without washing our hands, the bacteria on our hands will It will enter the injured person's body along the wound, causing ulcers and fever."

After Sancho finished speaking, Zhong Tang glanced at the back of her red hand. This must be the reason why she just slapped his hand away.

Noticing Zhong Tang's gaze, Sancho took the opportunity to apologize: "I was in a hurry just now, and I offended you. I hope Haihan will do it."

Zhong Tang put down his hand and shook his head indifferently, "You continue."

He is not a petty person. Since he already knows the reason and the other party is doing it for the injured, there is nothing to blame.

Sancho continued: "Keeping clean can reduce the entry of bacteria into the wound, and there are many ways to reduce bacteria, and high temperature is one of them."

"So when you treat wounded soldiers, you always wash your hands with soap and hot water, just for disinfection?!" A military doctor suddenly realized.
