Qing'er, you go and arrange for someone to buy all the sugar in Chang'an City back. ”

Li Kuan felt that such a black sugar was really unbearable.

Wouldn't the ice cream made when the time comes, also be black?

It's not chocolate ice cream, why do you want to be so dark?

"Huh?"

Listening to Li Kuan's words, Qing'er was stunned again.

What's wrong with your own prince today?

First, he asked people to buy all the saltpeter in Chang'an City, and then he had to arrange for someone to buy all the sugar in Chang'an City.

No matter how rich the palace is, it's not such a way to spend, right?

"Lord Wang, although this sugar is very sweet and delicious, it can't be used so much in the house for a while. Isn't it okay to just buy a few pounds and come back?"

At this time, Cheng Jingwen, the hostess, stood up and spoke.

"That's right, although the house is not short of this money, but the sugar in Chang'an City is tens of thousands of catties, and we can't use it that much."

Qing'er couldn't help but persuade on the side.

"Could it be that the prince bought these candies back, is there any other use?"

Wu Meiniang thought about it and felt that only this reason could make sense.

Li Kuan saw everyone's reaction in his eyes and showed a mysterious smile, "Buy the candy back first, and then you will know what this king is going to use it for." ”

With Li Kuan's instructions, there were immediately hundreds of servants in the annex of the Chu Wangfu, and the soldiers went to various squares in Chang'an City to buy sugar.

In just one day, first a group of people went to the city to buy saltpeter, and then the city to buy sugar, such a big movement, even if you want not to attract people's attention.

In the Xuanzheng Palace, Li Zhong stepped forward as usual to report to Li Shimin about the recent situation in Chang'an City.

However, looking at Li Zhong's cautious expression, Li Shimin felt that there was no good thing nine times out of ten.

"Your Majesty, there is one thing that is a little strange, but when it comes to His Royal Highness the King of Chu, Weichen thinks it is better to report it to you."

Li Shimin looked at Li Zhong, "What's wrong with Kuan'er?" ”

"Today, the Baiqi Division learned from various workshops that His Royal Highness the King of Chu arranged for many servants to purchase saltpeter from various pharmacies, and it is said that all the saltpeter on sale in Chang'an City has been bought out."

"Saltpeter?" Li Shimin showed a puzzled expression, "If I'm not mistaken, this thing is mainly used by Fang Shi for alchemy, right?" ”

At this time, Li Shimin had not yet begun to indulge in the alchemy of immortality.

However, whether it was Yuan Tiangang or Li Chunfeng before, they all mentioned alchemy to him, so he still knew a thing or two.

"That's right, saltpeter is the main raw material for alchemy, and basically no matter what kind of pill is refined, it will be used."

Li Zhong replied truthfully, although he felt that this answer might cause trouble for Li Kuan.

"What kind of Taoist priest has been invited to a banquet in the Chu Palace?"

"I've never heard of it!"

"That means Kuan'er, he wants to do his own alchemy? At this young age, he began to indulge in pills, what kind of system! ”

In Chang'an City, there are many nobles who secretly take pills, and Li Shimin also knows a little about it.

However, there is definitely no one like Li Kuan.

"Your Majesty, His Royal Highness the King of Chu has only arranged for people to purchase saltpeter, but his subordinates have not yet received the matter of someone refining the pill in the Chu Palace."

Seeing that Li Shimin was about to go crazy, Li Zhong hurriedly explained.

If something is abnormal, there must be a demon.

Especially when it comes to His Royal Highness the King of Chu, everyone thinks that he bought saltpeter for alchemy, but at this time, the final truth is often unexpected.

Li Zhong has seen this situation a lot over the years.

In case His Royal Highness the King of Chu is really not alchemy, it will be as if he is sowing discord in the middle at that time.

I can't bear this guilt.

"Humph! Isn't it, we'll find out in a few days. You make people stare a little more. ”

"The subordinates understand, and the other ......"

Li Zhong wanted to speak again and again, not knowing whether to continue.

"Huh?"

Li Shimin glared at Li Zhong with an unkind face.

"Your Majesty, there is another thing that is also related to His Royal Highness the King of Chu. In addition to purchasing saltpeter, the prince also arranged for people to buy all kinds of sugar, not to mention the sugar shops in the east and west cities, that is, in each workshop, but all those who sold sugar, no matter what the price, were bought by the people of the Chu Wangfu. ”

Without waiting for Li Shimin to deliver the goods, Li Zhong hurriedly finished what he wanted to say in one go.

In Li Zhong's opinion, this buying candy is nothing more than a little extravagant, and it should not cause His Majesty to be angry like buying saltpeter.

"Buying sugar? Bought all the sugar in Chang'an City? ”

Li Shimin was a little confused.

This Li Kuan, I didn't hear how much he loved sweets before.

Besides, no matter how much he likes it, there's no need to buy all the sugar in Chang'an City, right?

Jiulin Meat Pond, does he still want to learn from the king of business?

Li Shimin's face became more and more gloomy.

In the past few years, seeing Li Kuan's performance getting better and better, Li Shimin's love for him has also increased day by day.

Could it be that he's starting to float now?

At a young age, he was arrogant and lascivious.

That's not going to work!

"Your Majesty, you have indeed bought all the sugar you can buy. The people of the Hundred Horsemen saw with their own eyes that a carriage of sugar was transported to the treasury of the palace of the King of Chu. ”

Li Zhong didn't dare to lie, one is one, and two is two.

"Let people confirm it and see what Li Kuan wants to do."

Over the years, Li Kuan has always been able to come up with something unexpected.

Although Li Shimin is very angry now, he did not beat Li Kuan to death with a stick.

It's about letting people observe and confirm to see if things are really the way they think.

……

Gandy is the largest sugar merchant in West Market.

At this time, although sugarcane was planted in some places in Lingnan Road, it did not master how to make sugarcane into sugar, but saw more caramel sugar.

But Tianzhu is different.

At this time, Tianzhu was the world's best in terms of sugar technology.

Eighty or ninety percent of the sugar sold in Chang'an City comes from Tianzhu.

Due to the long distance, inconvenient transportation, and the sugar itself is not cheap in Tianzhu, the price of sugar in Chang'an City can be imagined how high it will be.

"Shopkeeper Gan, all the sugar in the shop was sold out today, and even a few hundred catties in the warehouse were bought."

Gandy had just returned from outside when the guy in the shop told him good news.

"Sold out? Isn't there already a lot of sugar transported this year, and why did it sell so quickly? ”

Gandy was surprised.

Sugar is a luxury in Chang'an, although the consumption has been rising in recent years, and he has expanded the supply, but he didn't expect to sell all the goods he had hoarded for three months.

"It's all sold out, do you want to arrange people to go to Luoyang and other places to transfer goods?"

Although Gandy himself only does business in Chang'an City, he has always been in contact with Tianzhu sugar merchants in Luoyang and other places.

Although the relationship between the merchants may not be reliable, if you increase the price a little, it is still no problem to transfer goods from other sugar merchants.

"Tune! Of course, tune in! It will take at least two months for the next batch of goods to arrive, and if you don't transfer the goods, won't there be no goods to sell in the store? ”

Gandy quickly made a decision to go to Luoyang in person and mobilize a batch of sugar back.

……

Kujou Kyoka's work was stopped by Li Kuan. Just the black sugar, it really affects the appetite.

However, Li Kuan didn't want so many people to know how he refined white sugar.

Let's just pause for a moment.

Leaving a few trusted people, he followed him into the kitchen.

Of course, before this, Li Kuan had already asked Xi Junmai to personally go to the ironmaking workshop to get some charcoal back.

In order to find out what material is best suited for steelmaking, different options were tried in the workshop.

Burning wood directly, burning coal directly, or burning honeycomb coal, or smelting coke first, all kinds of solutions have been tried.

Related products are also stored in the laboratory of the ironmaking workshop, including the activated carbon that Li Kuan wants.

"The fire can be bigger and melt faster."

I saw that in the iron pot, half a pot of water was filled, and all the catties of black sugar just now had been put into the pot.

"Rinse this charcoal and put it in together."

"Huh?"

Wu Meiniang paused, thinking that she had heard the wrong instructions.

The sugar refining technology itself is not very difficult, the key is that you have to think about it.

Li Kuan also counted on relying on this technique to pick up a wave of wool from the noble family, so even if it was nine apricots, he was not allowed to enter the kitchen.

There were only four people, Cheng Jingwen, Wu Meiniang, Qing'er and Li Kuan, and Xi Junmai was guarding the door.

Even the firewood on the stove was added by Qing'er herself, and Cheng Jingwen had nothing to do in the whole kitchen.

"Lord Wang, haven't you heard that charcoal and sugar can be eaten when boiled together?"

Not only did Wu Meiniang feel strange, but Cheng Jingwen couldn't understand it when she watched from the side.

At first, she thought that Li Kuan was disgusted that the icing was too dark, so she put it in the pot and refined it again, but ......

What is the operation of adding charcoal?

"Who said I was going to cook sugar and charcoal and eat it?" Li Kuan smiled and said, "Don't worry, just follow the instructions of this king, and you will be able to witness the miracle in a while." ”

The magic of activated charcoal, people at this time do not understand.

Instead of explaining so much, it is better to speak with facts.

After hearing Li Kuan say this, Wu Meiniang hesitated to put the charcoal into the pot, and then continued to stir gently.

There was a lot of water in the pot, but there was no movement for a while.

"Lord Wang, didn't you just say that you wanted to make ice cream? His Royal Highness King Jin and Princess Jinyang muttered that they wanted to eat ice cream when they left. ”

Qing'er's face didn't know when it was a little gray, and she was talking there like a big cat.

Li Kuan, Cheng Jingwen and others who watched couldn't help laughing.

"Qing'er, your face is covered with ashes."

Wu Meiniang couldn't help but remind.

She didn't say that it was okay, but when she said this, Qing'er reflexively wiped it on her face, and as a result, she completely became a big cat.

However, fortunately, there is no shortage of water in the kitchen, and there is no need to look at the firewood all the time.

A few people were chatting like this, and the water in the pot slowly decreased.

"I'll stir it."

Li Kuan saw that Wu Meiniang had been busy for a long time, and estimated that her hands were sour.

And this boiling sugar, the more it gets to the back, the more it has to be stirred.

Wu Meiniang also unceremoniously let Li Kuan step forward.

At this time, she also knew that there must be a reason why Li Kuan didn't let his subordinates in.

"Huh? Lord Wang, there seems to be something white in the pot? ”

Qing'er's eyes were sharp, and she soon noticed that there seemed to be something white in the bottom of the pot.

"This ...... What is this? ”

Cheng Jingwen also poked her head out curiously.

There was only water, charcoal, and sugar in this pot, and nothing white added to it.

Wu Meiniang reacted relatively quickly, and after thinking about today's events, she couldn't help asking: "Lord Wang, could it be that this white is sugar?" ”

"Ah, is this really sugar?"

Even if Cheng Jingwen is well-informed, she has never seen white sugar.

Don't say you've seen it, or you haven't heard of it.

Is there really white sugar in this world?

Or is the true color of sugar white?

Li Kuan: "That's right, this is white sugar!" ”

"Sugar?"

Cheng Jingwen and Wu Meiniang couldn't help but let out surprised voices at the same time.

"Lord Wang, why does the black icing turn into white sugar after being boiled like this?"

Qing'er asked Cheng Jingwen and Wu Meiniang's thoughts.

They participated in the whole process of refining white sugar, and they didn't see anything special added in the middle.

Could it be ......

"Charcoal? Lord Wang, is this charcoal the key to refining white sugar? ”

Wu Meiniang asked in surprise, feeling that this conclusion was really beyond imagination.

"That's right, there is no big secret to this white sugar refining, as long as other people know that adding the right charcoal to the sugar water, they can refine white sugar, so I don't allow so many people to appear here."

"The black frosting costs two silver coins and a tael, and it is not an exaggeration to sell this white sugar as white as snow for a gold coin and a tael. A simple treatment has skyrocketed the price of frosting several times, and this secret really has to be kept. ”

Wu Meiniang felt a sense of relief in her heart, Li Kuan didn't avoid herself for such an important matter.

"So, Lord Wang, you asked people to buy all the frostings in Chang'an City today, just to refine them into white sugar and then resell them?"

Cheng Jingwen finally understood Li Kuan's actions today at this time.

"That's right, this sugar refining technology is the only one in the world, and there is no other semicolon. It's more money than anything else. ”

Li Kuan's face also smiled, he didn't expect that eating ice cream could make so many things.

"Lord Wang, then you asked people to buy all the saltpeter in Chang'an City back today, so what is it for?"

Qing'er couldn't help but ask another question on the side.

This is also something that she has not figured out so far.

Wu Meiniang: "Yes, Lord Wang, this saltpeter should have nothing to do with sugar refining." ”

"Saltpeter naturally has nothing to do with sugar, but it has something to do with ice cream."

During the time when several people were talking, more and more white sugar had appeared in the pot.

At this time, Li Kuan finally had the idea of remaking ice cream.

Hey, these days, eating ice cream is so tormenting.

Fortunately, Datang already has sugar, otherwise I don't know how to toss.

"Ice cream?" Although Cheng Jingwen had heard of this word just now, she really didn't know what it was in detail.

However, Li Kuan didn't let them wait too long.

After filling all the sugar in the pot, let Kujo Apricot start to boil the milk and stir the eggs.

After a meal, they were packed into a row of glasses, placed in a large copper basin, and filled with water.

"Okay, put this copper basin in this big wooden basin filled with water, and pour saltpeter into the wooden shed."

Li breathed a sigh of relief and looked up at the sky, the sun was about to set.

However, the heat emitted from the ground did not decrease at all.
