Da Wei Chun

Chapter 305 Loyalty
After Gao Zhan left, Li Chengzhi called Li Rui in again, and told him how to filter and purify the purple sand after he bought it.

In fact, it is very simple, and it is exactly the same as the method of boiling nitrate: grind the purple sand into powder and put it into water, filter out the insoluble magnesium and iron, and then heat and cool to precipitate sodium chloride (salt), and the rest is ammonium chloride .

Just by the naked eye, there is no difference between this thing and table salt, fire sales, raw sales, etc.At that time, the guards such as Li Rui must be thrown into the pool, and Gao Zhan's people will only use nitrate powder...

In addition, Li Chengzhi told Li Xie to buy a large amount of "Yi", that is, maltose.

In this era, there is no word for "sugar", and the one made from malt is called "饱", and the malt sugar that is roasted or baked is called "饧", also known as burnt sugar.This is what is added to the plum wine and mulberry wine sold in the market at this time, so it has a bitter taste.

There is also honey, which is called honey, and that made from sugarcane is called stone honey.

In fact, these are far less expensive than what later generations say, and ordinary middle-class families can afford them.

Honey is the most expensive, followed by sucrose, and malt is the cheapest, at less than ten renminbi a catty.

Do the math: The price of wheat is about the same as that of millet. In a good year, it costs two cents per catty, while refined white rice and glutinous rice are slightly more expensive, at two cents per catty.One catty of wheat plus four catties of glutinous rice can yield half a catty of maltose. Calculated, the cost of one catty of glutinous rice is only six renminbi, and the selling price is at most ten renminbi.Cheaper to buy in bulk...

What is really expensive is frosting sugar, which only appeared in the Tang Dynasty, that is, granulated sugar.

Li Chengzhi bought sugar syrup, of course, to make smoothies: the maltized water is added to the water for making ice, and the frozen ice will naturally have a sweet taste.If you want more variety, you can also cut some fresh fruits such as peaches and apricots into it.

Wait for the ice to come out and pull it to the market, smash it with a few hammers, and pour some yogurt, cheese and the like. Isn’t this the fruit milk shaved ice of later generations?
It's much easier than making popsicle ice cream, at least you don't have to worry about how to cut the ice cubes into small pieces, and how to insert a stick into them.

Li Chengzhi did the math, the overall cost will not exceed [-]%. If you want to make something sweeter or melt more ice, you can basically control it at about [-]%. At least half the profit margin.

It is really not difficult to earn ten thousand dollars a month...

……

As soon as Gao Zhan returned to the mansion, he first sent a servant to watch over him, and called Gao Zhao when he came back.Then he locked himself in the room for nearly an hour.

There was a pack of nitrate powder on the desk, and a bucket beside it. Although it had melted for a while, ice flakes could still be seen in the bucket.

Gao Zhan was holding a copy of "Baopuzi Neidan", staring at a line of small characters on it, dazed.

"Use mercury nitrate and place it under the bridge to get silver frost..."

Don't think that there is such a sentence in the book that everyone knows it.When Gao Zhan went to Chongxu Temple (Tianshi Dao Altar in Beijing) to borrow books, he tried it intentionally or unintentionally. Even Tianshi Dao’s Danfang Gaogong (a senior Taoist priest specializing in alchemy) didn’t know that nitrate can also make frost. .

It is heresy to say that water pills (potions made with nitrate, sulfur, mercury, etc., which are more toxic) are heresy, and only golden pills are the right way...

The question is, how did Li Chengzhi discover such a strange thing that no one would believe even if he said it, and further developed it into ice?

It feels like there is really nothing in this world that he doesn't know...

Just as he was wondering, the servant knocked on the door and reported in a low voice: "Your Majesty, the Patriarch is returning home!"

"Understood!" Gao Zhan let out a sharp breath, and went to the front yard with the Dan book and the half bag of nitrous powder.

Gao Zhao was half leaning on the couch, and two beautiful maidservants were fanning him.Seeing Gao Zhan's solemn face, he knew that the youngest son had something to say, so he waved his hand away from the servant girl.

When no one was around, Gao Zhan handed the alchemy book to Gao Zhao: "Father, look..."

Gao Zhao took it subconsciously: "36 Fushuidan"... "Baopuzi"?
An evil fire surged straight to Gao Zhao's head: Is it this kind of mess again?

Just as he was about to reprimand him, he saw Gao Zhan was holding a bucket and pouring something like powder into it, Gao Zhao kicked it.

Gao Zhan was kicked right on the ground, and with a ouch, he fell back with the bucket.

"You bastard... Did you go to find Yuanyue under the pretense of looking for Li Chengzhi? You don't want to be a good official, but you still have Fu Shuidan... See if the old man can't beat you to death..."

Cursing in his mouth, he really searched for something.

No wonder Gao Zhao was angry, Gao Zhan was good at everything, except that he had a greater appetite, and he also liked to study some Taoist health-preserving techniques.

And it's not blind research. His "Health Preservation Theory" is definitely the first systematic treatise on diet therapy in Chinese history.

But that book is valued by people in later generations, plus he likes to hang out with Yuan Yue who also loves to study Taoism, and he is afraid of following others, so Gao Zhao will naturally think that he is not doing his job properly...

"How many times have I told my father to make you less associate with that Yuan Yue..."

Cursing, Gao Zhao chased him down with his fan upside down, but just as his bare feet stepped on the ground, he suddenly felt cold on the soles of his feet.

Looking down, there was a layer of ice under the feet: "Where did the ice come from?"

Gao Zhan is really wronged: just got kicked?
He rubbed his head and argued in a low voice: "The son really went to find Li Chengzhi, and he taught me the method of making ice with water?"

Gao Zhao wondered if he had heard it wrong: "What is it that uses water to make ice?"

"It's this ice!" Gao Zhan pointed to the ice flowers on the ground, "it was researched by Li Chengzhi from "Baopuzi": Even under the scorching sun, nitrate powder can be put into water to make ice... He asked his son This is what I do for a living..."

Gao Zhao was stunned.

Even the bucket and the water were brought by Gao Zhan from under the ice mirror, and they are absolutely irreversible.But just adding some nitrous powder, can it be frozen in the summer?
How is this different from witchcraft?

Gao Zhaomeng turned around and picked up "36 Volts of Water".

Gao Zhan explained in a low voice: "Li Chengzhi said: only according to the method in the book, nitrate powder can only form frost when it enters water. He studied for a long time before he found out the secret of making ice..."

Looking at the line of small characters above, the flesh on Gao Zhao's face twitched.

Ge Hong has been dead for more than 100 years, and this book is not a rare thing. Why did Li Chengzhi make ice before others researched it?
After studying for a long time, this technique is clearly given by God, and Li Chengzhi is just using this "Baopuzi" to deceive others.

I and Leopard really guessed right... Fortunately, I found out early!
The more he thought about Gao Zhao, the faster his heart beat, and even the sound of exhaling trembled.

Gao Zhan said again: "In order to prevent leakage of secrets, Li Chengzhi asked his son to carefully select loyal servants and servants, and make ice with his personal guards... He also said that if it works properly, it will not be a problem to produce thousands of ice a day. ..."

Gao Zhao froze suddenly.

Ice thousand dendrobium produced a day?
How much ice does Guanglu Temple distribute to civil and military officials every day?
This is simply turning water into ice... no, turning stone into gold!
If it is handled properly, January is more than ten thousand gold?
He took a deep breath: "What else did he say?"

What else can I say?
Li Chengzhi is really stupid, he wants to pay taxes?

Gao Zhan was 1 reluctant, but he obviously felt that Gao Zhao's mood was not right. He might call Li Chengzhi into the mansion in the next moment to intervene in person. How dare he hide it?
"He called it huge profits, and if he wanted to do it for a long time, he had to sort out the beginning and the end first... He also said that it was only for the sake of sharing the country's worries, and asked his son to ask you: Look at ten taxes and one line, five taxes and one is fine, but at most... ...At most, it can't exceed [-]%, otherwise there will be no profit..."

Gao Zhao was silent, and asked after a long time: "How much is [-]% gold?"

Gao Zhan felt distressed like a needle prick: "According to Li Chengzhi's calculation, how could it cost tens of thousands of gold in a month?"

"Ten thousand gold..." Gao Zhao sighed leisurely.

What kind of business can tax [-]%?

All over the world, never before!
Regardless of Gao Zhan, even Li Chengzhi was no different from the Gao family in the eyes of the emperor, so what did the actions of the two of them mean?
It is equivalent to Gao's donating the real gold and silver that he earned for nothing to the imperial court, and it is still tens of thousands of gold!

Li Chengzhi is clearly sharing his worries for Gao Shouwen...

If he knew that Gao Zhao was so good at brainstorming, Li Chengzhi would definitely be confused.

His words of "sharing worries for the country" were clearly addressed to the emperor: Look, have you ever seen a loyal minister like me...
