Soon, the entire Yucheng set off a beverage revolution.

Originally, there was no so-called iced herbal tea for customers to relieve the heat because of the high price of ice cubes in summer.

In the summer, the guests still come to the door with a pot of cooled herbal tea.

However, the heat is too hot in the middle of summer, and even if the herbal tea in the pot has cooled, it still makes people feel uncomfortable.

Today, Yucheng Dingjia has launched a large number of low-cost ice cubes with unlimited supply, and at the same time, it has also provided a variety of novel drinks for a number of teahouse restaurants.

This made Yucheng once again because of a seemingly inconspicuous thing, so that it indirectly caused a sensation in the entire Yucheng.

Yucheng, the originally hot weather, also because of the Ding family's large amount of ice, so that the hot weather showed signs of downward adjustment.

Originally, Shangguan Qiuyu made out perfumes, soaps and other luxury goods, although everyone loved them.

However, because of the price, these things are difficult for ordinary people at the bottom to accept for a while.

Now that this ice cube is out, it has made him earn enough money for the people of Yucheng.

Saltpeter makes ice, saltpeter is a thing that not many people know its use for now, and things that are not valued at all naturally do not cost anything.

Therefore, at the beginning of the Ding family's introduction of ice cubes, many merchants were attracted by its low price.

At first, people were willing to take advantage of the situation and buy a lot of money in order to make a lot of money.

However, it was later discovered that the Ding family's ice cubes seemed to be unsold at all, and no matter how many merchants bought them, it was useless, but they were not out of stock.

In the end, it led to the whole process of people rushing to buy.

For this reason, the Ding family had to cooperate with a group of small traders in Yucheng to sell ice cubes instead.

After all, there are nearly 100 million people in Yucheng, and even if the Ding family has a big business in Yucheng, there are not so many people to sell.

But even so, after one day, two days and three days, the sales of Ding's ice cubes have only increased, and there is still no sign of out-of-stock.

This made everyone dumbfounded, so someone from the government wanted to search the Ding family's ice cellar.

After all, if you sell ice in large quantities, how big should the ice cellar be to be able to hold these ice cubes?

However, the search for the Ding family was only a thought at most.

You must know that the current Ding family is no longer the original Ding family, and now the Ding family is backed by the Zhenguo Mansion, where do ordinary people from the government dare to come to the door to trouble the Ding family.

Therefore, it was originally a trivial matter, but in the end, even the emperor knew about it, and for this reason, the crown prince Xuanyuan Jing was also sent over.

In the living room, looking at Xuanyuan Jing, who was blushing at the moment, Shangguan Qiuyu glanced at him, took a sip of the iced juice in the cup, and was silent.

Calming down, Shangguan Qiuyu couldn't help but think about what Xuanyuan Jing had just said.

The Ding family's ice-making, obviously which emperor His Majesty is not a fool, naturally he will not be an idiot to think that the Ding family has built some huge ice cellar under their own house.

After all, if you want to supply the ice cellars needed by hundreds of millions of people in the city, you need to have a large area, and at the same time, how much manpower and material resources need to be spent to store these ice cubes.

Therefore, some smart people have already guessed that behind the Ding family's sale of a large number of ice cubes, they must have mastered some kind of ice-making method that they don't know.

This caused a lot of people to blush, after all, everyone is not stupid, and no one is not greedy for the huge benefits behind this ice cube.

However, to this day, the reason why no one dares to reach out to the Ding family is the Shangguan family behind the Ding family.

It is precisely because of this that Xuanyuan Jing will go directly to Shangguan Qiuyu, instead of going directly to Ding's house to ask Ding's family to hand over the ice-making method.

Although Xuanyuan Jing said that the royal family was not greedy for the money obtained by Shangguan Qiuyu to make ice.

Chief among them is the use of the ice cubes, which is valued by the royal family.

Dayu's territory is vast, in the middle of summer, many places are extremely hot, and the number of deaths of the people due to the heat every day is incalculable.

Therefore, the royal family wanted to get the Ding family's ice-making method from Shangguan Qiuyu, and then see if it was possible to apply this method to the hot and hot areas in the north to alleviate the hardships of the people.

And, of course, it is used in the military.

After all, the heat of summer is unbearable not only for the common people, but also for the armies that are heavily trained every day.

Shangguan Qiuyu also thought of this at the same time, so he sent someone to send the method of saltpeter ice making to his cheap grandfather as soon as possible.

Just imagine, millions of armies, marching and fighting in the middle of summer, the heat is absolutely unimaginable.

And at this time, what effect would the soldiers have if they could drink a sip of cold water?

Needless to say, it will definitely be able to make people's spirits rise instantly, and then the morale of the soldiers will be invisibly improved a lot.

As for the saltpeter ice-making method, Shangguan Qiuyu never thought of keeping it secret from the beginning.

After all, it's too easy to learn, and as long as the royal family really wants to know, they will know how it works with a little snack.

And Shangguan Qiuyu didn't have much hope of making money by making ice.

To put it bluntly, this thing is a scoop of water business, and the profit earned is the previous profit.

In addition, the sales period of this ice cube is also short, only two or three months of business, and ordinary people who will be bored to buy a large number of ice cubes in spring, autumn and winter.

Ordinary people don't buy it, and most of the big families have their own small Xiaoice cellars.

Therefore, this thing is clearly not a business worth investing in for a long time.

To Xuanyuan Jing's surprise, Shangguan Qiuyu didn't say a word, and directly told him the saltpeter ice-making method.

This made Xuanyuan Jing stunned for a long time, and then regretted it.

Because he was afraid that Shangguan Qiuyu would not tell him the ice-making method just now, he deliberately took it upon himself and agreed to Shangguan Qiuyu with five hundred god-destroying bows in exchange.

Five hundred god-destroying bows, each of which costs no less than one million silver taels, you must know that this is just the cost, not the selling price.

Then the God Destroying Bow belongs to the forbidden weapons of the Dayu Dynasty, which has a price and no market, and ordinary people can't buy it if they want to.

And the forces that can make the God Destroying Bow today can be counted on one hand.

Therefore, under Shangguan Qiuyu's smug face, Xuanyuan Jing regretted leaving the Guogong Mansion with a look of regret.

However, what Xuanyuan Jing didn't see was that the moment he left the Guogong Mansion, Shangguan Qiuyu's face immediately became gloomy.

Since returning to Yucheng, Shangguan Qiuyu has rarely gone out, except for an occasional trip to Beidaying outside the city, the rest of the time basically stays in the Guogong Mansion.

Now in the entire Guogong Mansion, except for the original three thousand iron guards, all the armor soldiers who were originally stationed in the mansion have been sent by Shangguan Qiuyu to the Beida camp outside the city to train with a group of Beijia knights.

As for the expansion of the Iron Guard, because the requirements for the selection of the Iron Guard are too strict, there is still a distance from the number of Shangguan Qiuyu 10,000 people.

However, under Shangguan Qiuyu's strict order, I believe that it will not be long before it can be assembled.
