The technology is not up to par, so the cost of disinfectant alcohol is extremely high!

Even if Li Yuanjia had ten sets of distillation equipment manufactured to ensure their food supply, it would only be dozens of jars a month. It's okay to supply it to the magnates in Chang'an City, anyway, when they really need it, they will obediently pay for it no matter how expensive it is.

But if you want to use it for the sixteenth guard, it's.

Not to mention that he can't build so much of a Han Wangfu, even if he can really build it, it is estimated that the second child will not be willing - it consumes too much food and is too expensive!

The lives of the Tang Dynasty soldiers in these years are really not worth so much money.

So seeing that the emperor's eyes were full of doubts, Li Yuanjia hurriedly explained: "Second brother, I asked Ma Yuan and them to try it, if you only use salt water, it is similar to using spirits...... Ahem, it's pretty much the same, so you can try it without the spirits first. ”

"Oh, that's right."

Hearing him say this, Li Shimin suddenly realized.

Then a flash of joy flashed in the emperor's eyes, and he nodded and smiled: "Yes, if it's just salt water, it will be much easier......"

"Second brother, it's not just salt water."

Taking advantage of the emperor's pause, Li Yuanjia quickly shook his head and said with a wry smile: "Salt water to rinse the wound is only one of them, but the more important thing is to be clean!" Salt water and spirits are only useful if the wounded soldiers are kept clean, and if they are kept clean, otherwise it will be in vain to use more. ”

"Hmm......"

Squinting at his younger brother for a while, Li Shimin suddenly chuckled and said, "So that's why you only drink boiling water and have to bathe every day?" ”

“…… Almost! ”

After being stunned for a moment, Li Yuanjia said calmly: "Brother Chen saw this statement in a medical book a long time ago, that is, toxins are everywhere!" Our bodies, hands, food, and water may contain all kinds of toxins, but most of the time the amount of toxins is very small, even if we eat and drink, there is no harm, but ...... These toxins are afraid of heat, as long as they are cooked, or boiled, they are absolutely fine. Therefore, the younger brother never drinks raw water, nor does he eat raw fish and meat, which is the reason. ”

The Tang people are quite fond of fish, and Li Yuanjia has never dared to touch it.

In fact, with his identity and status, even if he eats fish, he must have been carefully selected, but he will definitely not be served to him if there is anything wrong, but he always adheres to the principle of safety first, Li Yuanjia will definitely not eat it.

"Oh?"

Li Shimin's slightly raised brow showed that the emperor did not believe his brother's words at all.

Li Yuanjia is not surprised, if it is really so easy to convince the emperor, China's health level will not be a problem in an instant.

So he didn't dwell on it much, and soon took a deep breath and said, "Second brother, my brother suddenly had an idea in the past two days, that is, about the ...... of salt."

"Salt? What happened to the salt? ”

The brows subconsciously frowned, but Li Shimin seemed to think of something quickly, and his brows stretched out again: "You mean the salt water used to rinse the wound, right?" Hehe, how much refined salt can be used? If you don't have enough here, I'll have some for you. ”

"Uh...... Not this one. ”

The muscles on his cheeks twitched twice, Li Yuanjia gritted his teeth, and said with a straight face: "What my brother means is that I just thought of a way to make salt, which can be taken directly from the sea without boiling!" Not only can it save manpower and material resources, but the output is much more than the boiling method......

"What? What did you say? ”

At this moment, Li Shimin finally couldn't calm down, and stood up from the seat with a bang.

"Sure enough!"

His face was calm, but Li Yuanjia's heart jumped away with a bang.

Well, sure enough.

Even if there was no monopoly system of salt and iron in the early Tang Dynasty, salt, like iron, was definitely a strategic material in Li Shimin's eyes, and its importance was even comparable to grain. Therefore, when he heard that his brother could get salt from the sea, and that there was a simpler and more effective way, the emperor suddenly couldn't sit still.

There was some apprehension in his heart, but Li Yuanjia still said in a calm tone as much as possible: "You heard it right, second brother, when my brother was drinking tea recently...... Ahem, it should be said that when boiling water to make tea, I suddenly thought that since water can be boiled dry with fire, if we lead the sea water into a large pool, can it also be roasted dry by the sun? ”

"Roasted by the sun? How long will that take? ”

Li Shimin immediately understood what his younger brother meant, frowned and asked instinctively.

"Well, it's going to take a long time."

Licking his lips, Li Yuanjia smiled: "So the younger brother wants to find someone to try it and see how long it takes...... Mainly after checking the classics, I found that no one had ever tried it, and my brother couldn't help but be a little curious. ”

"Curious ......"

After listening to his words, Li Shimin was speechless.

Opening his mouth was like teaching his brother a lesson, telling him not to be whimsical all the time, but just when Li Shimin's words were just thought of speaking, his heart moved, and he swallowed back the words that came to his mouth.

Other people's words, it is indeed whimsical, but if it is Eleven Lang......

Looking at the tables and chairs around him, thinking about the stir-fried vegetables to be eaten later, and then thinking about the curved plough and the improved overturn, Li Shimin pondered for a moment and then suddenly said, "Eleven, what do you want to do?" ”

"Second brother, it's very simple."

Suddenly overjoyed in his heart, Li Yuanjia hurriedly said in an indifferent tone: "Brother Chen wants to find a place in Jizhou, send a few people over to build a big pond and try to dry salt in seawater." If it doesn't work, it's just a big deal, it's just a matter of spending a few dollars, and if it does, it's a great thing! ”

"Hehe, you'll make a lot of money if you do, right?"

Looking at the emperor whose face was a little dark, Li Yuanjia's heart suddenly sudden, and he quickly coughed twice and said: "Ahem, second brother, this time the younger brother really didn't think about making money by drying salt in the sea!" It is not easy for the people to eat salt, and the idea of the courtiers is that if this method is really feasible, they will sacrifice it to the court...... Dedicated to Your Majesty! First, it can give the people more cheap salt, and secondly, the inner library can also have some input every year, don't you say? ”

With a smile on his face, Li Yuanjia's expression was a little doggy.

What is important to him is not money, but the ability to make salting appear hundreds of years earlier. Anyway, he is an idle king, even if he really comes out, it is impossible to keep this business, at most, it is to share some soup and water, it is better to give it directly to the second child!

At least with Li Shimin's temperament, he definitely can't let him do it in vain, right?

Sure enough, after hearing Li Yuanji's words, the emperor was also happy: "Dedicated to me?" You have a heart. But since you have the idea, let's give it another try......"
