Datang: I was exposed by Princess Changle

After thinking that he could try to make a delicious iced drink to relieve the heat, Lin Xuan immediately put down his book, raised his head, and shouted loudly: "Butler Cui!"

"Butler Cui!" He called out again, but still no one responded.

When Lin Xuan saw that there was no one there, he couldn't help but feel a little depressed.

So in a deep voice, he ordered solemnly to the maid beside him: "Where is Steward Cui? Where is he now? Tell him to come over quickly!"

The maid replied reverently after hearing the words: "My lord, Steward Cui is probably reconciling accounts in the accounting room now!"

"Slave servant, go and call Steward Cui over here."

"Please wait a moment, my lord."

"Okay! You go." Lin Xuan calmed down when he heard the words, and responded lightly.

The most important raw material for making ice is saltpeter.

There is no saltpetre in the Furong Garden of the Royal Garden, so you have to send someone to buy it first!

Chapter 309 Your Majesty is really stingy!

After Lin Xuan drank a cup of tea.

"Young master, the old slave is here!"

When Lin Xuan heard the words, he saw Steward Cui trotting over from Lanting, and shouted out of breath.

After Steward Cui stood still, Lin Xuan commanded majestically: "Butler Cui, immediately ask a boy to go to the pharmacy outside and buy some Glauber's salt, the more the better! I'll be of great use!"

"Oh, that's right! It's not enough to buy a little, I have to buy all the thenardite in Chang'an City!"

"You try to arrange as many people as possible to buy it! Go right now! Buy it back as soon as possible!"

"Ask all the pharmacies in the entire Chang'an City to send all the thenardite in their stores to our Furong Garden!"

"After the big pharmacies deliver the thenardite to your door, you will find someone to check and accept it. If there is no quality problem, let them settle the money with you at the cash register."

"Butler Cui, do you understand?"

Saltpeter, called Glauber's salt or flame salt in ancient times, is only a kind of medicinal material in medicine shops, and it is not widely used.

"Young master, you... what did you say?! Bought all the Glauber's salt in Chang'an City?"

OMG!

The young master wants to buy the Glauber's salt in the entire Chang'an City? !

Did he hear it right?

Steward Cui looked at Lin Xuan dumbfounded when he heard the words, swallowed in disbelief, and asked stammeringly.

"That's right! Steward Cui, you heard me right! Buy them all, the more the better, hurry up and do it! I'll be of great use!"

Seeing this, Lin Xuan chuckled, waved his hand, and said happily.

What a godsend opportunity!

At this time in the early Tang Dynasty, there was no cold drink. What if he made ice out of saltpeter and sold it?

Then, this summer, the consumer demand in Chang'an City alone is enough to make him a lot of money!

Thinking about the billowing white money is particularly exciting, how could Lin Xuan let go of this lucrative good business!

"No! This old slave will do it right away!"

After receiving Lin Xuan's affirmative answer, Steward Cui no longer hesitated.

He hurriedly replied with a respectful face, then immediately turned around and ran outside quickly.

"Let's go, don't fan it! It's so hot outside, let me play chess in the room first!"

Lin Xuan ordered lightly to the maid who was shaking the fan gently.

"No! Young Master, you are so inspiring, what novelty are you going to invent? Can you tell Juan'er about it?"

The fan-wielding maid Juan'er looked at Lin Xuan eagerly and asked curiously.

"Secret, you will know in a while!"

Lin Xuan smiled and said with a mysterious face.

"Okay, son. Then we have to wait and see!"

The maid Juan'er curled her lips when she heard the words, but said disappointedly that she didn't get the answer she wanted.

Young Master, it’s true that the mysterious thing is going to be invented again, but we will all know it sooner or later!

After a while, Li Shimin came to visit again with his eldest grandson empress, Li Lizhi and eldest grandson Wuji.

After they chatted with Lin Xuan for a while, Li Lizhi was already sweating profusely.

At this moment, her face was hot and red, and she was very uncomfortable, and she kept wiping her sweat with a handkerchief.

So she frowned, and couldn't help complaining softly: "Brother Xuan, your inner room is so hot! Why don't you use ice!"

"Come here! Go get some ice!" Li Lizhi turned her head and told the maid of the Lin Mansion.

As soon as this word comes out.

Lin Xuan smiled lightly and nodded to the maid.

After getting Lin Xuan's permission, the maid of the Lin Mansion went down to fetch ice.

Then Lin Xuan said to Li Lizhi calmly, "It's natural to be calm!"

"Lizhi, please calm down first, the ice will be fetched in a while."

Li Lizhi felt a little ashamed when she heard the words, and she replied softly, "Yes, Brother Xuan."

Lin Xuan then handed her a cup of tea, and said lightly, "Lizhi, come on, calm down and have a cup of tea first."

"Okay, thank you Brother Xuan!" Li Lizhi said happily after taking the tea.

Seeing this, Li Shimin asked puzzledly: "Qinglong King, don't you have enough ice in Furong Garden?"

As soon as this word comes out.
