"When I went to Yunyue Restaurant, I met Yu Gongzi and them, and when they talked about your purchase of medicine, everyone was a little worried, so they came over to take a look." Deng Duoer explained to Lin Qiya like this.

"Hahaha, it's okay, I'll go to the pharmacy to buy something, it's not sick or anything, it just so happens that Young Master Cang is also here, I'll show you something good." Lin Yanya sat down with a smile and poured herself a cup of chrysanthemum tea and drank it in a big gulp.

"Good stuff? Listen to Wen Wen say that you are studying something to cool down? That's not the good thing you're talking about. ”

"Yes, you will know when the time comes, and it will definitely be useful in your restaurant. You guys wait a little bit. "Lin Qiya originally wanted to study saltpeter ice tomorrow, but now that Canghua Pond is just there, let's get it now, so as not to call him again later.

The three of them watched Lin Qiya take the big bag of saltpeter she bought and went into the kitchen, then filled half a bowl of water, put a little salt in the water, and took out some saltpeter powder and sprinkled it in the water.

Because there was very little water, when Lin Qiya came out of the kitchen with a bowl, the saltpeter in the water slowly melted.

The water in the bowl turned into ice, and you could feel the cold hand in your hand.

"Look!" Lin Qiya quickened her pace, after all, this bowl was really cold to her hands, and when she reached the pergola, she put the bowl on the table as soon as she walked to the pergola.

"It's ...... Ice? Yu Zimo looked at the condensed ice cubes in the bowl in surprise, knowing that it was ice, but he didn't believe his eyes.

Canghuachi touched it with his hand, and the cold air from his fingers clearly told him that this thing in front of him was ice.

"Awesome, how did you manage to keep the ice until now? Wrong! It's not a preserved disease, it's something you just made, right? Canghuachi knew that some big families would save ice in the winter for summer, but it was very expensive, and people who didn't have some financial resources didn't dare to do it, so after he said preservation, he reacted, this is not something to preserve, but a ready-made thing.

"Yes, with a little subtotal, this bowl of water is small, so it condenses quickly, and if you want a large amount, it may take five or six hours."

"It doesn't matter, you can make ice in the summer, this is not something that ordinary people can do, how did you do it?"

"Want a secret recipe?" Lin Qiya knew that Canghuachi knew that she could make ice, and she would definitely want to know the method.

"You're going to make this ice in front of us, isn't it just so that I can buy you this secret recipe?" Canghuachi complained, but said that he didn't want it in his heart, it was impossible.

"Hahaha, you think I'm losing money." Lin Yuya didn't care about Canghuachi's complaints, and then said, "The things you need are very simple, but the amount of pharmacies is always small, as a young master from Jinyi City, you should have a way to find a large number of this thing." ”

"What is it?"

"You promise me to send me ice twice a day when you make ice, and I'll put it in my storage room to cool down."

"It's all a trivial matter, you first say what you need, if you can't get the amount you said, it's in vain." Canghuachi doesn't think it's difficult to send ice twice a day, as long as the ice is made, it's no problem to send three or four times a day to this girl.

"Saltpeter, you need a sufficient amount of saltpeter, and this saltpeter can be reused, so the actual consumption is not much, but the first time you need a lot."

Everyone was a little surprised when they heard that it was saltpeter, but it was impossible for Lin Qiya to lie to them in this matter, and they only needed to go home and try it to know if what Lin Qiya said was a lie, so even if they were surprised, they were still willing to believe what Lin Qiya said.
