Because of the immaturity of technology and the defects of sealing materials, a jar of spirits above 65 degrees requires dozens of buckets of grain.

A sterile bag is not a sterile bag in the strict sense, not only cloth and cotton balls, but also steaming and sterilization, so there must be special tools and equipment.

The same is true for the needles and threads used to suture wounds, which must be carefully crafted with the best materials and must be steamed before they can be used. To do this, special equipment and bow saws are also required.

But anything that is specially made is certainly not cheap.

Especially the alcohol used for disinfection and the cotton used to make aseptic bags, the former requires a complete set of iron equipment, which is expensive, and the latter only has an output of 100 mu in Datang - without the emperor's approval, Li Yuanjia has never broken the red line of 100 mu!

Even the salt water is very distressing to use.

"I've made them use coarse salt and it doesn't work well!"

When it came to the end, Li Yuanjia looked helpless: "So if you want to prevent suppuration as much as possible, you must use refined salt...... Second brother, it must be refined salt! If you use that kind of coarse salt, you might as well use water! And after rinsing the wound, the salt is completely wasted! ”

“……”

After listening to his words, both Li Shimin and Cheng Zhijie twitched.

Nothing else, they were all shocked!

Originally, I thought that Ma Yuan's operation would look very simple, nothing more than using a little salt water, a little wine, and then a little cloth and some needlework, but the two big guys never thought that it would be so troublesome - salt water is special, wine is special, cloth and needlework are all special!

How much the does it cost?!

Of course, as the emperor and Lu Guogong, they will not frown even if it is expensive, but that means that when the number is small, the emperor is afraid of the large number!

Just the refined salt that Li Yuanjia said, how much can the entire Tang Dynasty produce in a year?

For a while, the expressions of the emperor and Lu Guogong were a little hesitant.

If the time was ten or twenty years in advance, they would definitely not have any hesitation, and they would definitely immediately order Li Yuanjia to brew this spirit in large quantities, and at the same time purchase refined salt on a large scale, encourage the cultivation of cotton, and no matter how much money was thrown in, they would not hesitate. Because at that time, Datang was fighting endlessly every year, and if he had these things, he could save the lives of thousands of sergeants!

That is not only human life, but also means morale, military morale, combat effectiveness, and a large amount of pension saved.

But now......

There are only a few rebellions every year, and there is an enemy like Tubo who hurriedly withdraws his troops without even seeing the main force of the army, is it necessary to spend so much money and effort?

The Tang Dynasty has only been founded for 20 years, and it is not so rich.

And after seeing the solemn expressions of the emperor and Lu Guogong, Li Yuanjia was not surprised at all, but shook his head with a wry smile.

More than a thousand years later, this little thing is a hair!

No matter what kind of thing, just find a company that can supply the whole country, and the cost is terrible!

A 100-milliliter bottle of alcohol costs only a few cents, and a pack of sterile gauze costs a few dollars - that's just the retail price, if it's wholesale...... Or if you calculate the cost, it's even cheaper, and the needle and thread are also cheap!

But in the Tang Dynasty that has been in Zhenguan for 12 years, it is a sky-high price!

Alcohol and saline alone can kill an individual.

The cost of alcohol Li Yuanjia knows best, how much money he threw into it, and it took him a month to brew so many jars. As for normal saline, refined salt is needed, and how much refined salt can Datang produce in a year? Not to mention that ordinary people are not even willing to use coarse salt.

So after listening to Li Yuanjia's explanation, the expressions of the emperor and Lu Guogong were so ugly.

And they also learned from Ma Yuan's mouth about the treatment of the wounded soldiers in the past few days, according to him, after being injured, they should eat more meat, eggs and other things every day to speed up the healing, which means that Li Yuanjia's method is more expensive, and the amount that needs to be allocated is even more terrifying!

After being silent for a while, Cheng Zhijie finally asked, "King, isn't there an easier way?" ”

Of course, it is fine for the magnates to use this method, but if they want to popularize it for the whole army, or even the whole country, it is too unrealistic.

"Hehe, of course there is."

After hesitating for a moment, a smile bloomed on Li Yuanjia's face: "It's actually very simple, only salt water is used after being injured...... If not, even boiled water is fine! Wash the wound thoroughly and use a steamed cloth...... Any cloth will do, just dress up the wound. It may be less effective, but it's certainly much better than what they use. ”

Glancing at Chen Feng, Li Yuanjia said with a smile.

“……”

Lowering his head slightly, Chen Feng didn't dare to make a sound.

If it was ten days ago, even if the other party was a prince, Chen Feng might dare to refute two sentences, but what else could he say now?

However, after listening to his younger brother's words, Li Shimin was quite surprised, clapped his hands and said: "If it's just like that, then it's no problem, haha!" ”

Refined salt is precious, but pumping some out shouldn't be a big problem.

As soon as his words fell, Li Yuanjia hurriedly added: "Your Majesty, in addition, it is necessary to keep the environment where the wounded soldiers are located clean, and maintain ventilation every day!" Not...... It is best to have someone take care of it every day, and the food and drink should also keep up...... If Your Majesty wants to try it in the army, you can let the two of them help. ”

Pointing at Ma Yuan and Huang Ren casually, Li Yuanjia's expression did not show any hesitation.

"Oh?"

Li Yuanjia's words surprised the emperor, and after also glancing at the two of them, he smiled meaningfully: "Old Eleven, are you really willing?" ”

In his opinion, Ma Yuan and Huang Ren are now "high-end" talents!

Li Yuanjia didn't care at all, just smiled and said: "As long as you have to need it, just use it as soon as possible, there are still people on my brother's side." ”

High-end talent?

It's just that he simply learned how to deal with wounds, and Li Yuanjia has no interest in such "high-end" talents! And he also needs someone who can help break into the military and educate them about "new technologies" such as disinfection and stitching!

In Li Yuanjia's view, Ma Yuan and Huang Ren are just transitional talents.

He didn't even expect the two of them to do anything, and it was already a huge success to be able to promote the concept of disinfection and stitching.

As for the latter things, it naturally depends on the children in the current Wangfu Primary School.

Those who have been cultivated since childhood are the talents that Li Yuanjia needs.

So after making sure that Cheng Zhijie's expression was a little moved, Li Yuanjia couldn't help but smile and said, "Otherwise, these two people will go to Lu Guogong to try it first?" ”
