"Lady, call our son to study! Learn this, and you won't have to worry about eating and drinking for the rest of your life. "

"Oh, this seems to be the Western medicine mentioned by the light curtain, at first glance, it is really different from our medical skills. "

"I'm a butcher, I'm good at knives, it's decided, I'm going to change my career to learn this, and become a doctor to save lives and help the wounded!"

“......"

The enthusiasm of the ancient people was high.

Medical technology that they had never seen before, made them excited.

Anyone with a discerning eye can see who can learn to operate, even if it is just to help others stitch up their wounds, it is enough to feed themselves.

It's much better than farming as a farmer.

Decent and rich!

And even happier are the group of people who are already doctors.

The eighty-year-old Chinese medicine doctor went out on crutches and trembled with excitement after seeing it.

Then two lines of tears burst out with remorse.

No way, my hands are shaking when I'm old.

Now that I have learned how to operate, I don't dare to do it for others.

I regret that I didn't see it decades earlier!

Otherwise, how many people can be saved...

Qin Dynasty.

The people of the doctor celebrate together.

The long-awaited Western doctor finally appeared....

"Knives, scissors, needles, we have all these tools. "

"Disinfection?" (If you read a violent novel, you can go to Feilu Novel Network!)

"Toxic in the air??"

"It is necessary to sterilize by boiling water by fire and boiling water..."

Everyone was lost in thought.

They don't understand the principle, and they simply don't want to think about it when they find that they can't figure it out.

The most important thing is to save people, and as for why we do it, we will study it later.

"Alcohol disinfection. "

"This is a good solution, and it can be distilled with other liquors. "

"The operating room should also be disinfected..."

"It's a waste of alcohol to have surgery. "

The healer was silent.

Unexpectedly, the biggest problem with surgery is that there is not enough alcohol to drink.

Han dynasty.

Zhang Zhongjing, a medical saint, pondered while recording.

The knowledge of light curtain science has greatly enriched his medical theory. []

This includes the fact that there is a virus in the air.

He never wondered why he would put a tool on the fire to burn it when cutting a wound or stitching it up.

Now he knows why.

Zhang Zhongjing nodded happily, "In the future, you can use the knife on the patient with peace of mind, and you have to prepare some alcohol." "

5.8 Three Kingdoms Period.

Hua Tuo was going crazy with joy.

"Surgery!"

"It's surgery. "

"My craniotomy is definitely also an operation. "

"It seems that the preparation was still insufficient, there was no operating room, disinfection was not in place, and even the tools were not well prepared. "

"Prime Minister, Prime Minister, you are saved!"

Hua Tuo shouted.

This remark instantly aroused the dissatisfaction of the soldiers leading the way, and he pushed it and shouted: "What are you shouting! The prime minister's illness has been cured, you dare to curse the prime minister!"

"Come in, the prime minister is waiting for you. "
