Speaking of ice, you should always use ice in your shop, especially those teas and so on.

It's almost summer, and a lot of things can't do without ice, so shouldn't you find a way to make some of them?

At night, Gu Tingcheng lay on the bed thinking about ice-making techniques.

"Lady, what do you want?" The night was heavy and looked at Gu Qingcheng in a daze.

"The night is heavy and cloudy, is there ice in the night country in summer?" Gu Chengcheng looked at Ye Chongyun, Ye Chongyun is the prince, he should know more.

"Yes, why did you think about asking Bing?" Ye Chongyun didn't know what Gu Qingcheng wanted to do.

"I'm just asking, how do you preserve the ice? Or is there ice-making technology? Gu Tingcheng was very curious.

"There's a special ice room, but as for what kind of ice-making technology you're talking about, there's none. The ice room is managed by people who know martial arts with internal force, after all, the summer is very hot, and the royal family and nobles use ice a lot. ”

Because not all royal nobles know martial arts, especially those female harems, there are still a lot of ice used in summer.

"Okay." It is worthy of royalty, and there are special people who use internal force to manage the ice room.

"What, lady, do you want ice? I'll have someone get it for you. Ye Chongyun looked at Gu Qingcheng seriously.

"How did you get it? Where to send from? The ice room of the Royal Palace? It's sent, but it's not all turned into water? Gu Qingcheng looked at Ye Chongyun with a pig-like expression.

"No, let people protect it with internal force, and make sure that they come here, it's still ice." Ye Chongyun supported his head with one hand, lying on the inside of Gu Tingcheng and fanning Gu Tingcheng with a fan.

Although the weather is hot now, Gu Qingcheng can't feel it, because she is a person with internal strength to protect her body.

However, because there are mosquitoes in this mountain village, Ye Chongyun helped her fan the wind, and she did not refuse.

Listening to Ye Chongyun's words, Gu Qingcheng rolled his eyes ungracefully.

"Let people protect them all the way with internal force? There's no need for such luxury, besides, it's just a drop in the bucket, and far water can't save the near fire. ”

"What does the lady want?"

"Make your own ice, do you believe it?" Gu Qingcheng smacked his big eyes and stared at Ye Chongyun.

"It's a bit bizarre, but as long as you say it, I believe it." Ye Chongyun looked at such a lovely Gu Qingcheng, and was stunned for a moment and said.

"Really? Then let's try it tomorrow. ”

"Okay." Although Ye Chongyun didn't know how to try, no matter what Gu Qingcheng wanted to do? He supports everything he does.

The next morning I had breakfast

Lucina is going to catch shrimp again in the morning, and she is addicted to eating.

Gu Tingcheng asked Honghua and Xiaoliu to go together to get some back, and it was okay to eat it later.

It is important to know that only this season of shrimp is the most common and the fattest time.

Then I studied the ice-making technique at home.

Gu Tingcheng remembered that the book he had read before said that an ore called saltpeter was used to make ice in ancient times.

It is a colorless, white, or gray crystalline form.

It blends easily into the water, and when it melts, it absorbs a lot of heat, which causes the water to turn into ice.

But is this saltpeter here? What's your name?

"Night heavy clouds, night country, are there any fireworks?" Gu Tingcheng thought about it and asked this question, because it was the fireworks that appeared first, and then people made gunpowder.

And this saltpeter, which is an ingredient in the manufacture of gunpowder and fireworks, is mined from mines.

"Yes." Ye Chongyun was a little puzzled, why did Gu Tingcheng not know if there were fireworks in the night country?

You must know that every year, fireworks will be set off in the Night Country.

There are even small fireworks sold at some stalls.

But after thinking about it, it is understandable, Gu Tingcheng doesn't like to go out and walk around very much, so he naturally doesn't know what is going on outside, and this place is far away from the imperial city.

There won't be any big fireworks, after all, fireworks are not something that can be put off in ordinary places.

Places like these will only sell small fireworks.

However, with such an explanation, Ye Chongyun felt that it was still a little reluctant, after all, Gu Qingcheng was not an ordinary person.

My own lady really has a lot of secrets.

"Then do you have any materials to make fireworks, can you ask someone to find me some?"

"No problem, I'll find it for you now."

"Hmm."

Gu Qingcheng watched Ye Chongyun go out, and thought about what else he had made ice in ancient times, and whether he had missed it.

After all, she hadn't done it herself, she had read it in some books before, and she hadn't paid much attention to it.

After thinking about it for a long time, I decided to wait for Ye Chongyun to get the materials back.

Just as he was about to go out to take a look at the factory, he saw Lucina and the others coming back with a man on their backs.

The man was still wet.

"What's going on?" Gu Tingcheng asked Xiao Liu.

"We went to catch shrimp, and after a while, we saw this man floating on the grass by the river not far away. After a look, she was still alive, and Morning Lucina seemed to know each other, so she brought it back. Xiaoliu explained.

"You go get a doctor first, and I'll go in and take a look." Gu Qingcheng instructed Xiao Liu to bring the back basket over.

"Okay." Xiao Liu didn't care that the clothes on his body were wet, and immediately flew out again.

"Morning Lucina, do you know him?" Gu Tingcheng asked after entering.

"Allure, it's him." Lucina pointed to the lying man and said with some excitement.

Gu Qingcheng was a little inexplicable, and seeing that Ali was a little silent, he didn't plan to ask him.

After carefully looking at the lying person, this face seemed to be a little familiar.

It seems to be

The man I ran into last time I bought a lantern!

Morning Lucina also particularly liked the type.

"You fished him up from the river?"

"That's right, he still has a knife on his body, it can't be that he offended someone, right? It's a good thing the face wasn't scratched, otherwise I wouldn't have recognized it. Lucina said heartlessly.

"Ali, you can change his clothes first, and we will go out first in the morning Lucina." Gu Qingcheng pulled Lucina, who was a little reluctant to move.

"Okay." Lucina was a little reluctant in the morning, but she went out anyway.

"You like that man?" After going out, Gu Chengcheng asked Lucina in the morning.

"I don't know, I just like his face." Morning Lucina thought for a moment and said simply.

"You still don't like his face, a man's face is unreliable. Don't let down the people who really love you. Gu Tingcheng said meaningfully.

Morning Lucina also understood, and turned Gu Qingcheng a little embarrassed.

"What do you say?"

"It's not like I said anything, I just saw that someone just now didn't seem to be very happy, but I think about it, if I see the person I love, I like others so much, so surprised, I will be unhappy when I think about it."

"But I didn't do anything, why should I be unhappy?" Lucina glanced inside the room, but the door was so closed that she couldn't see anything.

Suddenly, I felt a little depressed. Is Ali angry?
