Zhang Xiaohua!

Xia Qianqian remembered that the last time she saw her, she was hiding in the grass on the green hills in ragged clothes, hungry and in a miserable state.

At the beginning, she suggested that she stand up and prove Luo Hong's crime.

As Luo Hong's favorite concubine, Zhang Xiaohua has some feelings for him.

She hesitated.

Xia Qianqian felt pity for her, so she gave her a few taels of silver and asked her to leave this place and live a good life.

After so long, she has almost forgotten this person.

Unexpectedly, her name appeared in her mind again.

But how could Zhang Xiaohua have the poison of a bloodthirsty dead snake?

She did not express the doubts in her heart.

After all, these are just her speculations without evidence.

The crowd in front of the carriage is getting bigger and bigger, and it won’t be possible for a while.

Geng Zhong asked for advice, "Sir, a group of people from the Jiang Mansion are kneeling at the door of the General's Mansion, demanding that the General's release be released. The two parties are in a stalemate for a while, and I'm afraid the crowd will not be able to dissipate."

"Detour!"

"Yes!"

The carriage in the green tent turned around, and originally only needed a stick of incense to go home, but unexpectedly it took half an hour to get back to the Xia family.

When Xia Qianqian got off the car, Mr. Liu was waiting anxiously at the door.

Seeing her coming, the anxious look on his face disappeared, and he trotted forward, "Girl, hurry up, there are some things in this book that I really can't figure out."

Xia Qianqian looked back at the carriage, and Mr. Liu noticed that there were people in the carriage.

He quickly calmed down his expression and cupped his hands towards the carriage, "Sir, you are back."

Ji Zimo lifted the car curtain and got out of the car, "Mr. Liu held the book and studied it all night last night, but he still hasn't studied the book thoroughly?"

"This book is exquisite!" Mr. Liu was amazed and couldn't help but sigh: "It seems to be some very common things and very simple principles, but if you study carefully and understand it, you will find that the mystery is unfathomable.

!"

Such a powerful book, this girl actually threw it to herself like waste paper.

This girl is really brave!

Is it possible that she has more powerful books?

There are many, many more...

When he thought of this possibility, Mr. Liu's heart beat wildly.

I respect Xia Qianqian more and more, and the thought of wanting to become her teacher suddenly pops up again.

"These are the most basic!" Xia Qianqian opened her mouth, confirming Mr. Liu's guess.

"What about those essences?" Mr. Liu asked closely.

"You must understand these contents first before you can talk about the rest!" Xia Qianqian answered matter-of-factly.

Mr. Liu's face suddenly turned red.

Yes!

How could he forget?

The most important thing to avoid when studying medicine is being impatient and biting off more than you can chew.

The process of studying medicine is a step-by-step process. He once led his apprentices and instilled this concept into his disciples. However, when it was his turn, he no longer knew what it meant.

"Then let's..."

"Go to my study!" She suggested: "You must practice some operations before you can help me skillfully during tomorrow's surgery."

"Okay!"

The two hit it off immediately, turned around, returned to Xia Mansion, and went straight to Xia Qianqian's study.

Ji Zimo, who fell behind them, was completely left out.

He shook his head helplessly and followed the two of them slowly.

In the front, Mr. Liu looked like a young boy. He didn't have time to go to the study. He held the book in his hand and asked seriously: "Girl, what are the differences between disinfection and sterilization? There is an explanation in the book, but I still don't know."

Understand..."

"You have to open your imagination on this one! In fact, in the vast world, we are the human world, and there is also a micro world that is invisible to our eyes."

"We can't see it, so how do we know it exists?"

"Use a microscope!"

"What is a microscope?" Mr. Liu turned into a curious baby.

"A microscope is something more powerful than clairvoyance!" Xia Qianqian opened the study door and explained: "Mr. Liu, come and take a look, this is a microscope."

There is really a precise microscope placed on the table in the study room.

"This..." Mr. Liu came forward and looked left and right.

He has never seen such a thing, and he doesn't know how to use it.

Ji Zimo, who was following behind, also stood aside, looking at the delicate things on the table with doubtful eyes.

"This thing allows us to see the microscopic world!"

She took out a small glass piece from the box on the side and said, "Mr. Liu, please put your finger on it and press it."

Liu Lao clicked it excitedly.

Xia Qianqian dropped a drop of the coagulation liquid, then put the slide under the lens of the microscope, "Here, take a look."

Mr. Liu wanted to take a look and caught a glimpse of His Highness beside him who was also eager to try. He hurriedly greeted: "Your Highness, you go first!"

Ji Zimo stepped forward slowly and followed her instructions, raising his eyes forward.

"Close one eye and look with the other eye!"

He did as he was told, and in the blurry vision before his eyes, clear veins suddenly appeared, and the veins were filled with some cheerful and jumping things.

In my ears, the girl's voice explained word by word: "This is the thumbnail of Mr. Liu's fingerprint."

"Those veins are his fingerprints, and the things jumping in the water droplets are some bacteria adhering to his fingers."

Ji Zimo watched quietly, and after a while, he raised his head.

Mr. Liu couldn't wait to see it, and then his whole body trembled. When he raised his head, he rubbed his hands vigorously, "Why are my hands so dirty?"

Geng Zhong was at the end of the queue. Seeing Mr. Liu raise his eyes, he hurriedly stepped forward and blinked, "There are so many bugs, Mr. Liu, what did you just do? Did you destroy the bug nest?"

"That's not a bug!" Xia Qianqian corrected: "That's a bacteria!"

"In real life, in the world invisible to the human eye, in that micro world, there are many species. Their names are bacteria, viruses, fungi, mycoplasma, chlamydia..."

"These things have different shapes and different functions, and they coexist with humans."

"Doesn't that mean there are bacteria all over our body?" Geng Zhong's back felt numb after hearing this.

How come this bacterium is more powerful than the Dark Guard, able to exist in the human body as invisible?

"Yes!" Xia Qianqian said firmly: "Bacteria are not just one kind, but also divided into thousands and thousands of species. Some are good for the human body, but without them, the human body will get sick. Some bacteria are harmful to the human body, and if you are infected, you will get sick."<

/p>

"For example, wound infection is caused by bacteria."

She was talking about bacteria in a serious manner, and the three grown men on the side were stunned for a while.

In the end, Mr. Liu was the first to react, "So, for tomorrow's surgery, you require that everything used in the surgery needs to be sterilized. This means that all bacteria must be killed."

"Yes, if there are no bacteria, there will be no infection."

Xia Qianqian explained with a serious look: "Tomorrow, once your hands are wearing sterile gloves, you cannot touch anything outside the surgical area to prevent the gloves from getting infected."

"Mr. Liu, if the surgical towels I need for the operation are ready, ask Brother Geng to bring them over. I need to disinfect them all tonight at the latest."

"For what?"

"Pressure cooker!"

This is another new term.

"Can I help?"
