On the surface, Li Yuanjia tried his best to keep an indifferent attitude, but in fact, his heartbeat at this time was definitely much faster than usual, and someone could hear it when he was lying on his chest.

He wasn't worried about Huang Ren and Ma Yuan's debridement and suturing at all, because this thing was played by Li Yuanjia in his previous life, and he did it many times when he was rotating in the emergency department in the first two years of work. To be honest, it doesn't even need to be that troublesome, as long as you clean the wound well and wrap the wound with various fabrics that have been steamed and cooked, you can save a large number of people!

The limitations of the times are vividly demonstrated in this field.

One is the limitation of knowledge, in the future, anyone who will come out will know that the wound must be cleaned and disinfected, otherwise infection may occur, and even someone will have to get tetanus or something like if they have a small injury; But in this Zhenguan year, not to mention the concept of disinfection, it is a routine operation to grab a handful of plant ash to stop bleeding when injured.

Then there is the limited conditions, there is no need to go to the hospital in the future, many people have iodine volts, cotton swabs and other things at home are always spare, and band-aids are not rare, but in the Tang Dynasty of Zhenguan for thirteen years, any textile can be used as currency, and only large families will have reserves at home, and ordinary people will have ......

Hehe, there is a slightly cleaner set of clothes to wear, which is basically a well-off level.

How to compare?

Therefore, the debridement suture technique that Li Yuanjia took out is a real magic technique in this era!

Before this, the Tang sergeants were injured and could only resign themselves to fate, one to look at personal immunity, one to look at the weather, and the other to look at the conditions on the battlefield at that time; But after the birth of debridement and suture, there can be a fourth influencing factor, and that is the treatment of field doctors......

This is Li Yuanjia's self-confidence, the self-confidence of a surgeon.

But he asked Han Lucheng to count the night blindness patients under the Han Wangfu, and then use pork liver...... is the practice of treating pig liver, to be honest, Li Yuanjia really has no score in his heart. He knows that one of the wishes of night blindness is a lack of vitamin A, and he also knows that pig liver is rich in vitamin A, but eating pig liver can prevent it is certain, whether it can really treat Li Yuanjia is not a spectrum at all.

After all, when Li Yuanjia was a doctor, he really saw a doctor with night blindness......

Well, he hadn't heard of it anyway.

In fact, not only night blindness, but also many of the same types of vitamin deficiencies, such as scurvy lacking in vitamin C, rickets lacking in vitamin D, etc., Li Yuanjia has only seen it in books, but he has never seen it in reality.

And the treatment of diseases is never so simple.

On the basis of no relevant clinical experience, Li Yuanjia can only try little by little to verify the trivial knowledge in his memory.

The use of pig liver to treat night blindness is barely a start.

Of course other people don't know Li Yuanjia's careful thoughts, such as Fang Fengzhu, who is very strange in his heart at this time. Of course, she also knew about night blindness, and knew that many people could not see anything at night, basically like blind people, but he could not understand why the king was interested in this disease, which was not a disease.

I can't see anything at night, what's wrong?

But just think about this kind of thing, of course Fang Fengzhu will not be stupid enough to say it directly, but began to pester Li Yuanjia to learn the thing called abacus. Ever since she knew that the speed of the abacus was much faster than that of using Tianzhu numbers to calculate, she had actually been thinking about it, but she didn't have time to think about it some time ago.

Li Yuanjia was naturally pleased with her studiousness, and immediately asked people to bring two abacus, and the couple crackled in the study......

……

When Li Yuanjia taught the princess to play abacus at home, and when he was leisurely, there was a conversation about him in a place in Chang'an City.

In the Zhengguo Mansion, Mrs. Wei finally discovered her daughter's abnormality, and then discovered the six math books she brought back from the Han Palace. These six books not only surprised Mrs. Wei, but even led Zheng Guogong himself.

After roughly flipping through the contents of the first volume, Wei Zheng couldn't help frowning.

Obviously, he didn't like it.

As a very traditional literati, Wei Zheng doesn't like all "strange and obscene skills", especially the numbers invented by Tianzhu people and some strange symbols in this math book, which makes him even more disliked. There are also those so-called punctuation marks, although Li Yuanjia explained at the beginning, and he could understand what it meant at a glance, but I don't know why, Wei Zheng instinctively felt uncomfortable after seeing these things......

There's no reason, it's just uncomfortable.

As if these punctuation marks were something very rebellious, Wei Zheng wanted to reach out directly and completely deduct them from the book!

Looking at the uncertain expression on her father's face, Wei Shuyue was apprehensive in her heart, and asked carefully: "Father, what do you think...... How is the book? ”

"Humph! Vulgar! ”

Raising his eyebrows slightly, Wei Zheng replied lightly.

"Huh?"

After hearing these words from her father, Wei Shuyue was visibly stunned, as if she couldn't understand why he said this, and bit her lip before justifying: "Father, daughter...... I think this Tianzhu number is very useful, although I have only read less than half of the book, but I found that both writing and simple calculations are better than ......"

"Alright, no need to say it."

Without waiting for his daughter to finish speaking, Wei Zheng waved his hand and said impatiently: "Since you like it, it doesn't hurt to learn and watch, but don't indulge in it!" ”

“…… Be. ”

Seeing her father's impatient look, Wei Shuyue really didn't have the courage to defend again, so she could only lower her head and respond angrily.

"Okay, you continue to read, and go first for your father."

Flicking his sleeves, Zheng Guogong Wei Zheng walked out of his daughter's small study, and the moment he went out, his face instantly became a little strange.

The feeling just now is really a little weird!

For a while, Zheng Guogong was also a little confused about his thoughts, which is a rare thing in ordinary times. However, after hesitating for a moment, remembering the folds he hadn't finished writing, Wei Zheng still took a deep breath and walked quickly towards his study.

And until her father's footsteps were getting farther away, Wei Shuyue exhaled lightly and picked up the books on the table again.

She really likes this Tianzhu number.

Although it was only the beginning of learning, Wei Shuyue had already discovered the convenience that Fang Fengzhu said, just writing a single writing does not know how many times easier than traditional Chinese characters! There are also those so-called calculation formulas, even if they haven't figured it out yet, it doesn't prevent Wei Shuyue from comparing them with her eyes!

So after looking at the cover of the book for a while, the little girl gritted her teeth, turned to the page she saw before, and continued to read carefully......
