Li Yuanjia's ultimate goal is, of course, 70% alcohol.
That is disinfectant alcohol.
Although the medical use of this thing is very limited, for this era, it is the most cost-effective way to disinfect. The simplest disinfection method he can think of is alcohol.
He didn't even dare to think about iodine and iodine.
Even if the configuration of iodine is slightly simpler, where can he get natural pure iodine? He has no idea at all.
So the only hope is alcohol.
In fact, generally speaking, 60% to 95% alcohol has a sterilizing and disinfecting effect, but the best effect is between 70% and 75%.
Li Yuanjia couldn't satisfy Li Yuanjia's needs with 40% alcohol.
So after telling Han Shan that he needed stronger wine, and the stronger the better, Li Yuanjia let them use the wine freely. Anyway, the method had told them that whether it was the improvement of the distillation equipment or the control of the temperature, it was up to them.
It’s just a matter of exploring. Even if Li Yuanjia personally participates, I’m afraid he may not be able to do better than them.
As the head of the family, he just needs to wait for the results.
But when he was about to leave after receiving the order, Han Shan hesitated and asked: "Your Majesty, this wine is so strong and transparent, if... ahem, I mean if it is sold, there should be some in the winter.
A lot of people are willing to buy it, right?"
"Huh? Take it out and sell it?"
After listening to Han Shan's words, Li Yuanjia was stunned for a moment, and then looked at his housekeeper with a strange expression.
This old antique, is he proposing to let the palace sell wine?
How rare!
However, Han Shan didn't know what Li Yuanjia was thinking at this time, and thought that his words had made the king unhappy, so he quickly slapped his face twice with his hand in panic: "My king, forgive me, Han Shan is talking too much!"
"Haha, it doesn't matter."
Naturally, Li Yuanjia would not blame his old butler. He just smiled and waved his hands and said: "I'm just a little surprised that you can think that this kind of wine will only be popular in winter... Haha, but this wine consumes a lot of food and is brewed in large quantities.
And if I sell it, I’m afraid there will be trouble!”
The sky is vast and the earth is vast, and the food is the largest.
In any feudal society, food is the most important material.
Distilled liquor is good in everything else, but it consumes too much grain. In addition, due to the losses caused by poor craftsmanship, one kilogram of liquor often consumes several times or even ten times more grain than other alcoholic drinks! For a country that was only twenty years old when the country was just founded,
For the Tang Dynasty, this price may be a bit high.
If he rashly brewed it on a large scale, Li Yuanjia was afraid that he would be raped by ginseng, let alone sell it.
It's not that Han Shan didn't understand this, he just didn't think of it for a while, so he immediately nodded and said: "The king is very concerned. Han Shan was rash!"
"hehe."
Seeing Han Shan's slightly regretful look, Li Yuanjia's heart moved, and he suddenly smiled and said: "Actually, it's not impossible, but... let's talk about it after a while! You continue to make wine and see if you can make something stronger.
I’ll check on the situation later!”
In the blink of an eye, Li Yuanjia thought of a possibility.
If he, an idle prince, rashly uses a large amount of grain to make wine, he will definitely arouse criticism, and even the "upright" imperial censor may even ask for a copy of him. But if the person who gave the order is the emperor, and
What if it is still good for Datang?
So Li Yuanjia raised his eyebrows and asked, "Han Shan, how big are the tea gardens in Jiangnan now? How much tea can be produced every year?"
Although he was a little surprised that the king would suddenly ask about tea, Han Shan immediately answered: "In reply to the king, the land in the mountains of Jiangnan is cheap, and the king attaches great importance to the tea, so he has bought four of them.
More than a thousand acres! If we were to produce tea every year... I'm afraid it would only be over two thousand kilograms now!"
"More than four thousand acres, more than two thousand catties?"
After hearing what Han Shan said, Li Yuanjia was stunned.
Is tea production so low?
Right?
Even if he doesn't know much about how much tea can be produced from one acre of land, if the output is only this small, the future tea farmers will not lose their lives? And when the roasted tea was sent two years ago, this didn't seem to be the case, right?
Han Shan naturally nodded to this and immediately gave an answer: "Your Majesty, the main reason is that most of the tea trees are newly planted, so it will take a year or two to harvest."
"……Understood."
Rolling his eyes, Li Yuanjia smiled mockingly.
He knew that tea trees cannot be planted to produce tea that year, but Li Yuanjia forgot that most of his thousands of acres of tea gardens were bought last year and this year. Even if enough people were hired locally, the tea trees planted were not
The method will yield harvest in the same year.
So after pondering for a moment, Li Yuanjia waved his hand and said: "Okay, I know this. Let them take care of these thousands of acres of tea gardens. I will be of great use in the future!"
"Yes, Your Majesty!"
After nodding in agreement, Han Shan hesitated for a moment, then asked: "What about this distilled liquor, let's..."
"Don't stop, keep brewing!"
Narrowing his eyes, Li Yuanjia said calmly: "While trying to brew stronger wine, keep the brew for me! Before winter this year, prepare at least two hundred jars for me..."
…
Just as Li Yuanjia was secretly preparing for the future of tea and liquor, Wei King Li Tai was having a conversation about him in the Yankang Room southwest of the palace.
"Father, was this Tianzhu number created by King Han?"
After getting another addition question right, Li Xin was so happy that she pulled Li Tai's sleeve and asked. It was usually very difficult to learn mathematics, but after using these Tianzhu numbers, it suddenly became easier. This made the little boy
The prince became interested in the great uncle mentioned by his father.
"King Han? Of course not!"
Smiling and shaking his head, Li Tai's chubby face was full of kindness: "They said they are Tianzhu numbers, so naturally they were created by Tianzhu people. King Han is just... um."
Although he is only eighteen or nineteen years old this year, as the son of the Emperor of the Tang Dynasty, Li Tai may be really "talented" and gave birth to his eldest son Li Xin early. He is Li Xin's age and let Li Yuanjia know
I couldn't help but shed tears in the end. When my uncle is still focused on being a "monk" behind closed doors, are you angry that my nephew's son can do so much?
However, despite his young age, Li Tai is quite caring about his eldest son.
So when Li Xin was studying the math book brought back from Prince Han's mansion, Li Xin saw him and clamored to learn it, so Li Tai spent a few days teaching him. Unexpectedly, this little guy learned faster than him!
Halfway through his words, Li Tai suddenly stopped.
Frowning slightly, King Wei suddenly felt a little strange: since his Uncle Eleven clearly stated that he learned these numbers from books from Tianzhu, why had he never seen or even heard of them?
?
Narrowing his eyes, Li Tai suddenly felt suspicious.
However, after thinking about it for a while, Li Tai quickly put aside this small thought, lowered his head and asked with a smile: "Xin'er, do you think it is easier for the math taught by the teacher, or the one taught by your father?"
Li Xin didn't hesitate about this, and immediately nodded her head: "Of course my father taught me it's easy!"
"Ha ha!"
Seeing his son's innocent look, Li Tai burst out laughing, and then patted Li Xin's little head happily: "In that case, from now on, father, I will teach you mathematics every time... ahem, I will teach you math when I have time.
