In the Zhenguan era, such a thing as iced juice should not have appeared.

These days, everyone likes goat's milk, yogurt, rice wine and the like, and even tea with onions, ginger, garlic and salt is not very popular, let alone juice - fruit is not a good thing that everyone can enjoy, not to mention that except for the palace and the nobles, who can afford to use ice in the summer?

But Li Yuanjia's arrival has changed a lot of things.

Although the efficiency of saltpeter ice making is very low, and if the amount is not enough or the purity is too low, it cannot be made at all, but sometimes you don't have to have ice cubes to drink cold juice. As long as saltpeter can lower the temperature of the water, the effect is actually similar to that of ice cubes, not much different.

So in the summers of the past few years, there has been no shortage of chilled juice in Han Wangfu.

Naturally fresh and nutritious.

Although there is no juicer or anything, making juice has become a complete chore, but without Li Yuanjia doing it himself, Yu Niang and Chunyan can naturally do it all.

Idle is idle, what's wrong with sweating?

In the summer of the eleventh year of Zhenguan, Li Yuanjia had completely brought himself into the aristocratic mentality of feudal society, and he would no longer feel embarrassed to let the maids be busy making a glass of juice for half an hour. In fact, when the two girls were busy in the tofu workshop all day and couldn't straighten their waists when they were tired, Li Yuanjia said at most "Today's tofu is good" at the table, which was the biggest praise for them.

If you really want to say thank you or something, I'm afraid it will scare them......

Far from it.

So when Han Shan said with a solemn face that there was a chilled juice in the East Market, and it was sold for ten big dollars a bowl, Li Yuanjia understood what he meant after a little thought.

Not many people know about the "exclusive secret" of saltpeter ice!

Emperor Li Shimin must have known it, the emperor and the concubine, the crown prince Li Chengqian, and Li Yuanjia's younger brother Li Lingkui, his father-in-law Fang Xuanling and his uncle Yu Wenshi and ...... If the number of Chang'an City is full, there should not be more than ten! Moreover, this technology was sent by Han Wangfu, and no one would pull down their face to do this business, and the little money they earned was not enough to be ashamed.

Seeing Li Yuanjia's abrupt expression, Han Shan asked cautiously, "King, do you want to send someone to investigate?" I've heard that their ice is not cellared in winter, it is made out of nothing......"

"Chacha? Why check? ”

After listening to Han Shan's words, Li Yuanjia gave him a strange look.

"Uh......"

was stunned for a moment, and Han Shan didn't know what to say for a while.

Why check?

Of course, it is to find out where their ice cubes come from, if it has nothing to do with Han Wang's Mansion, if it is really to steal Han Wangxian's ice-making method, it is natural to let them understand that our king is not easy to mess with!

In Han Shan's opinion, isn't this a matter of course?

"Hehe......"

Soon guessed Han Shan's thoughts again, and Li Yuanjia laughed.

In these years, the common people are basically digging in the soil, and if there is no land, they will rely on their crafts to live, so blacksmiths, carpenters and papermakers regard their craftsmanship as more important than life, otherwise they will not pass on men and women at every turn, and pass on inside and outside or anything, not to mention the great ability of making ice in summer.

So it's not surprising that Han Shan has such an idea.

And the meaning of his words is nothing more than to go to the East Market to check the shop that sells chilled juice, if it is opened by the Fang Mansion or Yu Wenshi and the people in the mansion, after all, they are all Li Yuanjia's relatives and elders, but if it is someone else, they can naturally let them see the anger of King Han......

However, after laughing, Li Yuanjia waved his hand and said, "Okay, Old Han, it's just a method of making ice, and it's not a powerful thing...... Hehe, let them go. ”

Saltpeter ice making is not even a technology, and in this day and age it is at most a natural phenomenon. If this Li Yuanjia also wants to keep it secret, then he simply doesn't take anything out in his life, and it's all stuffy in his heart. He is a prince of the Tang Dynasty, he has no shortage of food or drink, and he has never thought about who to fight with to get rich, nor can he blatantly do business, so why should he hold it in his hands?

So no matter what Han Shan thought in his heart, Li Yuanjia was not interested in investigating this matter.

And he also knew that if he could get the technology of saltpeter ice making and dare to open a shop in the East Market, he was afraid that he would not be an ordinary person, otherwise Han Shan would not have hesitated a little just now. There's really no need to make a big deal for such a small thing that can't make a lot of money......

……

After Han Shan left depressed, Li Yuanjia narrowed his eyes.

The appearance of chilled juice in Dongshi is really nothing to him, a cup of juice is ten big children, this is not something that ordinary people can afford, and even people with small family properties want to drink a cup I am afraid they have to weigh it, after all, it is the price of dozens of catties of grain!

So after the appearance of this thing, it is destined to be a luxury that only a small number of people can enjoy.

And Li Yuanjia knew that there would definitely not be too many such people in Chang'an City. In addition, saltpeter is not a particularly rare thing, and the method of making ice Li Yuanjia was also handed over to Fang Xuanling and his uncle, and it should soon spread to their friends and colleagues.

In other words, this thing is not really valuable.

But someone can get this method and dare to sell it on the East Market, which can't help but make Li Yuanjia a little puzzled in his heart - if it is the handiwork of a certain big man, it seems a little too stingy to do so; But if it was leaked out by someone from a big man's mansion, then his courage would inevitably be too great.

The unique cheats of the Prince's Mansion can also be sold casually?

After pondering for a long time, he couldn't figure out why, Li Yuanjia drank the juice in the cup in one gulp, and simply put this matter aside.

With July approaching, now is not the time to worry about these trivialities.

There is news from Luoyang that the emperor will return to Chang'an by mid-July, and in two months, it will be the day when Li Yuanjia's filial piety period will expire.

For him, it will be a key node in his life.

It is not a big deal to live in the Shengyefang mansion rewarded by the emperor, because Li Yuanjia does not have high requirements for residence, and even the eldest daughter who is about to marry Fang Xuanling, a famous minister through the ages, is not important, because as early as the day he knew that he already had a fiancée, Li Yuanjia had already accepted his fate, and he knew that he was not qualified and had no ability to resist such an arrangement.

But the expiration of the 27-month period of filial piety means that Li Yuanjia will usher in freedom.

Although there is still limited freedom, after he has established the image of a pure filial prince, and Li Shimin's wariness of his younger brothers has been greatly reduced, this freedom is enough to ensure that Li Yuanjia can live the life he wants......
