A month passed unconsciously, and the person had never come back since that time, and Jian Ning even began to wonder if the person had really existed? Or was what he said that day just to tease her?

The business of Shiweiyuan really lived up to Jian Ning's expectations, and it has always been the envy of others. Few people can afford to book the No. 1 private room, but the rest of the private rooms do not have a day to spare, and they also need to be booked in advance to have a place, so that Jian Ning has more free time, and Jian Ning can't help but be a little bored when this time is free, especially in ancient times when there is no entertainment at all, Jian Ning feels that the whole person is not very good.

After lunch, Jian Ning was really bored in the incense courtyard. She didn't have the habit of taking a nap, and even if she did, it was because she couldn't stand the heat. While enjoying the chilled fruit, he pulled Xi'er and chatted.

"Xi'er, you said that on such a hot day, if you didn't have this cold and cold food, how would you live?" Jian Ning's current requirements have dropped by a star, when she first came, she often howled for air conditioners and fans, although no one understood, but now she is most satisfied with being able to have chilled fruits to eat every day.

"Miss, what you said is not right. If you look at those Hanako on the street, not to mention eating chilled fruits, you may not even be able to eat rice. Xi'er said while fanning Jian Ning.

"Huh? Aren't we rich here? Didn't you see what Hanako appeared on the street? What Jian Ning said is indeed true, she has been here for almost a month, and she has gone out a lot of times, but she hasn't seen much of it.

"Miss, that's because every place you go, rich people go. Although Yangxin County is rich, there are also poor places, and there are beggars. Xi'er said plainly, but Jian Ning listened carefully.

"They generally can't enter the city, and they live in some dilapidated temples and dilapidated houses in the suburbs. Even if you come in, you won't appear on the most prosperous street in Yangxin County, usually near the back door of some small alleys or restaurants. ”

"And Miss, let alone call Hanako, in fact, ordinary people can't afford to eat these. Ice cubes are very expensive, and there must be an ice cellar to keep ice cubes available all the time, and this ice cellar is only available to wealthy families such as wealthy businessmen or officials, except for restaurants like ours. As soon as Xi'er started talking, she couldn't stop, and she talked more and more.

"Xi'er, where did all the ice cubes in our food garden come from? How much does it cost? Jian Ning was originally still struggling with the matter of calling Hanako, but after hearing Xi'er say so much, an idea suddenly popped up in her mind.

"Well, I really don't know so much about Xi'er, if Miss wants to know, go and ask Shopkeeper Liu." Xi'er told the truth, her main job is to serve the young lady, and she is not clear about many things about the food garden.

Jian Ning paused, put down the chilled fruit in her hand, pulled Xi'er over and said, "Xi'er, you go and see if your senior brother is busy, if not, let him come here." ”

"Okay." Xi'er went out in response.

A quarter of an hour later, Xi'er and Liu Leshan entered the courtyard one after the other.

"Senior brother, what is the price of this ice cube? Where did it come from? Jian Ning got straight to the point and asked straightforwardly.

"There are two types of ice in the ice cellar, one is the ice stored in winter, which is usually used to refrigerate ingredients. There is also an ice cube made of saltpeter, which is relatively rare, but can be used, and the ice used for the chilled fruit that Ning'er eats is made of saltpeter. Liu Leshan didn't know why Jian Ning asked this, but he still answered her question truthfully, because Liu Leshan knew that Jian Ning never asked useless words.

"Saltpeter? Brother, is this saltpeter ice safe? Will you have a problem eating? "Saltpeter ice? Jian Ning only knew that saltpeter was used when making bombs, and he didn't think that saltpeter was also used to make ice. Saltpeter is supposed to be a chemical element, isn't it harmful to the body?

"There shouldn't be, those rich businessmen and high-ranking officials, and even the palace often use saltpeter to make ice for the master to cool off, I haven't heard of any accidents!"

"Senior brother, is this costly high?"

"It's not too high, but ordinary people can't afford it."

"Well, senior brother, go buy some saltpeter and buy some more fruits, you can't waste such a hot day!" Jian Ning already had a calculation in her heart.

An hour later, Liu Leshan came to Ningxiang Courtyard again with a piece of prepared ice, some saltpeter, fruits, etc.

Jian Ning looked at the piece of ice, a little difficult, this ice bar is not big, it is not small, there is no such thing as an ice crusher here, how to get it?

"Senior brother, is there any way to chisel this ice cube apart?" For this kind of technical problem, Jian Ning has always been thrown to Liu Leshan.

"I'll let someone chisel this." Liu Leshan simply took the ice cube and walked out.

After a while, he really came back with the chiseled ice, Jian Ning used a small bowl to hold half a bowl of crushed ice, then poured the mashed watermelon juice on it, and finally put some chopped apples, watermelons and grapes, put a small spoon, handed it to Liu Leshan and said, "Senior brother, taste it, what do you think?" See if you can get those who have money to pay for it? ”

After Liu Leshan took it, he scooped a spoonful with a spoon and slowly put it into his mouth, and suddenly felt that the whole person was cold and comfortable.

"Ning'er, this is delicious, and it also kills the heat, but this method of making zuò is not difficult, those people can make their own zuò, why spend money to buy it from us?" Liu Leshan thought farther than Jian Ning, and the question he asked hit the nail on the head.

"This" Jian Ning was only thinking about how to make money just now, but she didn't expect this question. Indeed, people have ice, fruits, and people at home, so why spend money to buy them here?

"Senior brother, then let's make it a little different and make it taste unique. When you start making ice, you start working hard to make it special. "Jian Ning has always had ghost ideas, and this thing can be seen and learned at a glance, but what ingredients are added in the ice-making process is the thing behind it, and there is no way to learn it.

"Senior brother, you go to the front first, I'm experimenting to see what ingredients can be added to make the ice taste the best and the most special, and I will let Xi'er get what you need." Jian Ning has been bored for so long, and now she finally has one thing, and all of a sudden, the blood in her whole body is boiling, and she is full of energy.
