Become a feudal king from today

"Liu Fu, are you going to buy some bitter salt?"

The sun is past noon.

Zhao Xu thought that the wealthy people from Yan County were probably coming soon.

So he asked Qin's accountant to take out ten taels of silver and give orders to Liu Fu.

Zhao Xu nodded.

In ancient times, bitter salt was a laxative medicinal material and was sold in drug stores.

In modern times, bitter saltpeter is called saltpeter.

The way he used this time to steal silver from the wealthy families of Yan County was to use saltpeter to make ice.

In ancient times, people in the north stored ice in cellars in winter and took it out to cool down in summer.

There is also an organization in the imperial city that specializes in ice storage management.

In the summer, ice was included in the rewards given by the emperor to his ministers.

Therefore, ice has always been expensive in ancient times.

For Da Song, ice is even more precious.

The reason is that the imperial city of Dasong is Jinling, which is the contemporary Nanjing known as the Four Great Furnaces.

Unlike the north, it is not too cold even in winter, and there is no thick ice to mine in winter.

In his memory, there had been very few snowfalls in Jinling City in the past two years.

Therefore, when the hot summer comes, Jinling City, or the entire south, will fall into an ice shortage.

Wealthy people want to buy ice to cool down, but they can't get it.

And this also led to the saying that summer ice has the same price as gold in the South.

It's hot summer now.

If you can sell a lot of ice in Jinling City, you will definitely be able to earn a huge amount of wealth.

"Buy three catties and go back quickly." Zhao Xu told Liu Fu after handing the ten taels of silver to Liu Fu.

Liu Fu nodded and returned with a small bag of saltpeter in just one stick of incense.

The heat made his clothes completely soaked.

After wiping his sweat, he gasped and said, "Your Highness, is the bittern coming?"

Zhao Xu nodded and asked Liu Fu to find two porcelain basins of different sizes.

Not long after, the servant came to report that someone from a wealthy family had arrived.

Zhao Xu asked Liu Fu to lead them to the front yard.

"Why did His Highness ask us to come here?" said a wealthy man with a big belly and a silk dress.

Looking at the dilapidated palace, he couldn't help but feel a little contempt in his eyes.

The dignified palace was so shabby that it was even worse than the courtyard where their servants lived.

But it was normal for him to think about it. No prince had ever been to Yan County since the founding of Dasong.

This Prince of Yan is the first one, and the prince who can come here is basically no different from being exiled.

The emperor will not give such favorable conditions.

"His Royal Highness said that he will perform a skill for you when everyone arrives." Liu Fu copied the exact words.

"Hahaha……"

Everyone burst into laughter.

"Is King Yan really cured of his madness?"

"It's probably not good, otherwise why would such a ridiculous thing happen?"

"Hey, it's gone, it's gone, it's just nonsense." Someone was about to leave.

At this moment, Zhao Xu walked out of a room.

"I have met His Highness King Yan."

Seeing Zhao Xu, everyone began to salute.

But many of them just bend down slightly and show off.

Zhao Xu saw this and was not angry.

One day, he would have these people kneeling and singing conquest to him.

"No courtesy." Zhao Xu waved his hand.

He had asked Liu Fu to memorize the names of these people.

He knew exactly whose family the servants came from and whose family the master came from.

In the future, we will know which wealthy families can be won over.

"Everyone, please be patient. I am not fooling you. Just wait a moment and you will learn about an opportunity to make a fortune." Zhao Xu said.

Seeing that King Yan had come forward in person, everyone stopped and decided to take another look, maybe just for fun.

Forty or fifty people stood together and waited.

At this time Zhao Xu entered the room.

He put the small porcelain vase into the large porcelain vase and filled it with water.

Wrap it in cotton cloth again.

The principle of making ice from saltpeter is that when saltpeter dissolves in water, it absorbs a lot of heat and can theoretically drop the temperature to minus two degrees, eventually turning the water into ice.

The purpose of the big basin and the small basin is to use the saltpeter in the big basin to cool down and turn the water in the small basin into ice.

In this way, the ice in the small basin is edible.

After all, saltpeter is still poisonous.

The cotton cloth is to isolate the heat from outside.

After the ice making is completed, just dry the water in the large basin, the saltpeter will precipitate out again, remove the lost part, and the rest can be used repeatedly.

After all this is done, it’s time to wait.

"about there."

After waiting for a quarter of an hour, Zhao Xu opened the cotton cloth.

The moment the cotton cloth was lifted, a burst of white mist rose inside, and the air was freezing.

Thick ice has formed in the small basin.

Feeling happy, he came to the yard carrying the ice in the small basin.

"Everyone, please see, this is the performance I mentioned." Zhao Xu took the ice and walked around in front of everyone.

"It's ice." someone exclaimed.

"This summer is so hot, where is the ice?"

"Incredible."

"..."

There was a murmur.

Liu Fu also opened his eyes wide in disbelief.

Apart from buying bitter salt, Zhao Xu did not let him participate in any process.

He didn't know how Zhao Xu had changed it.

"Not only did King Yan recover from his madness, why did he become so powerful?" He exclaimed in his heart.

"Your Highness, could this be the ice in the ice cellar?" someone asked.

This is also what others have in mind.

If not, then does this King Yan have magical powers?

"No, this is what I did. It is the art of turning water into ice." Zhao Xu straightened his chest.

When these words were said, the wealthy people immediately went crazy.

"Could it be that His Highness knows the magic of gods?" A person was shocked.

"No, it's just an ordinary skill. If I teach it to you, you can do it too." Zhao Xu glanced at everyone's faces to see their reactions.

Now, many people have completely lost their contempt for him.

Some people are thoughtful,

And some people's eyes are shining, obviously thinking of ways to make money.

"Dong An, the eldest son of Dong in Xiayan County, came to see His Highness and hoped that His Highness could teach him this technique." A young man came forward.

This person has a fair complexion and looks very elegant.

"The Yang family in Xiayan County also hopes to be supported by His Highness." Another person came forward.

Among the people, many people have already figured out the taste.

Some smart slaves have already run home.

Those stupid ones looked confused.

Zhao Xu nodded secretly, there are many smart people in the wealthy families of Yan County.

After all, they have a lot of resources and have been studying and doing business since they were young.

It's easy to figure out Zhao Xu's intentions.

By this time, he was no longer secretive.

"As we all know, ice is expensive in the hot summer in the south of the Yangtze River. It is June now and the hot summer has just begun. If you understand this ice-making technique, you will definitely earn a huge amount of silver in the imperial city or even in the south of the Yangtze River."

After a pause, he said, "The king came to you to teach you this technique. After all, I have no royal orders and cannot leave the fief. Naturally, I cannot return to the imperial city to earn this money. However, this Naturally, the secret technique cannot be given away for free.”

Zhao Xu said it so straightforwardly that everyone woke up.

Someone asked: "Jiangnan ice is expensive, but how much does it cost to make ice?"

"It can be said that you can make a lot of money." Zhao Xu said.

At this point, everyone could no longer remain calm. They were all smart people.

Dasong's Jiangnan is the richest in the world. If he really masters this ice-making technique, he will definitely become rich.

At that time, their strength will be greatly increased.

So, someone shouted excitedly at that moment: "Your Highness, how much silver do you need to learn this secret technique?"
