Seeing Xiao Nan and Shen Binglan looked incredible.

Qin Yu smiled faintly, "What? Is it difficult to turn water into ice?"

Xiao Nan: "???"

Shen Binglan: "???"

Light water to make ice!

This is not a difficult question at all, it is an unrealistic question at all.

Xiao Nan widened his eyes and said blankly: "Brother-in-law, are you sure you are not kidding?"

He was talking.

"Your Highness, your well water."

Deng Bao had already brought people to carry Jingshui in.

"Of course it's not a joke!"

Qin Yu said, looking at Deng Bao, "Eunuch Deng, I'm going to get some saltpeter for me, it's of great use!"

Saltpeter is a natural ore that has appeared in this era, but it has no other purpose except for a small amount of processing to be used as medicine, so the amount of mining is not large.

"Saltpeter?"

Deng Bao was stunned and then said, "It's the little prince, I'll go to the Imperial Hospital to get it for you."

Qin Yu said: "That's not enough in the Imperial Hospital. If you take people to the western suburbs to dig, dig up a few carriages and come back, this is of great use."

"Yes, little prince." Deng Bao answered and then left the hall.

He should do his best to do his best to what Qin Yu ordered.

Xiao Nan listened and said in confusion: "Brother-in-law, what did you ask Deng Bao to dig saltpeter?"

Qin Yu smiled, "Of course it's just a little water to make ice, you'll wait and see later."

Saltpeter?

Light water to make ice?

Xiao Nan really doesn't know how to connect these two things together.

Deng Bao went to find saltpeter, and Qin Yu and the other two waited in the hall.

In this era, ice is a rare thing. In order to relieve the heat in summer, the Ice Secretary was established in the palace.

Ice is usually taken in winter and then stored in ice cellars and ice wells.

In addition to being used to cool indoors, it also has the effect of keeping meat and vegetables fresh, and even drinking it directly in water.

But no matter what method it is, ice is very precious in this era.

Only the palace and some nobles can use it.

But this year the weather is hot early and very hot, so the ice cubes are consumed very quickly.

It was just morning, and I was so hot that I was afraid of people.

One hour later.

Deng Bao brought people back to the East Palace.

Saltpeter is not a rare thing in this era, and caravans of saltpeter are transported to the East Palace.

Qin Yu asked someone to find a large wooden barrel and porcelain jar and put it in the hall.

After the things were ready, Qin Yu began to make ice.

"Come, pour water into the wooden barrel!"

Qin Yu was commanding on the side.

Several small eunuchs poured well water into the large wooden barrel.

Xiao Nan and Shen Binglan didn't understand what Qin Yu meant, so they could only stand aside and watch quietly.

moment.

The big wooden barrel was almost filled with water.

Then, Qin Yu found a rope, nailed a net into the wooden barrel, and then put a porcelain jar filled with water into the wooden barrel, so that the mouth of the bottle was exposed and not contaminated.

After it is done.

Qin Yu waved his hand and said, "Come, put saltpeter into the wooden barrel."

Then, several eunuchs began to put saltpeter into the wooden barrel.

The principle of making ice in saltpeter is very simple.

When saltpeter dissolves into water, it absorbs a lot of heat, which will cool down and freeze.

However, saltpeter is poisonous, so Qin Yu put some porcelain jars in the wooden barrel, which contained clean water.

In this way, the ice cubes in the porcelain jar can be eaten, and the ice cubes in the wooden barrel can be used to cool down, which is simply killing two birds with one stone.

As saltpeter continues to be thrown into the barrel, a large amount of heat begins to be absorbed by saltpeter, and the water in the barrel slowly changes, and a hint of coolness slowly disperses.

"It's frozen! The water in the wooden barrel is really frozen!"

"Oh! It's so amazing, it's so amazing! The little prince is so amazing!"

"This...how is this possible!? Is the little prince an immortal descending to earth??"

......

The little eunuchs looked at the ice in the wooden barrel and were all surprised to hear the sound of their ears.

They were really shocked by Qin Yu's magical means.

Not to mention them, even Xiao Nan and Shen Binglan were so surprised that they couldn't stop talking.

It's really a magical way to turn water into ice.

Xiao Nan felt the chill emitted from the bucket, looked at the ice in the bucket, looked at Qin Yu again, and was dumbfounded, and exclaimed: "Sister... Brother-in-law, just show up with us! Are you

It’s not that the gods descend to earth, you... you are a bit too much, how is this possible!?”

Shen Binglan stood beside the wooden barrel, his eyebrows were fixed,

She could see that this was indeed not a fool, but a real ice.

Can saltpeter freeze when it enters water?

this......

Why hasn't anyone ever discovered this?

Qin Yu was light and light, "What kind of god came to earth, and the water was used to turn into ice, and saltpeter dissolved water to absorb heat and freeze. This is called scientific means, and this is called chemical reaction. Do you understand science?"

"Even if you let the dog carry saltpeter into the barrel, it can freeze."

Xiao Nan rolled up his sleeves and couldn't wait to say, "I'll try it."

Qin Yu: "..."

After saying that, even dogs are OK, he insisted that he wants to give it a try. It's really hard to persuade the damn ghost.

Qin Yu said lightly: "You try it, we need to make a lot of ice."

Then, Qin Yu directed the eunuchs to start smashing the ice, put it in a basin, and then put it in various places in the hall to cool down.

He made a few more ice buckets and put the wine filled with porcelain bottles into the ice bucket and chilled it.

It was already noon.

The arrangement of the side hall has only been completed.

The air in the hall was much cooler, and there was basically no feeling of scorching heat.

Qin Yu invited musicians and dancers to reward wine, "Girls, drink a glass of iced wine to relieve the heat, this young master will appreciate it."

Qin Yu drank all the best wines collected by Emperor Wei and were tributed by the Western Regions during the previous dynasty.

They are not qualified to drink on weekdays.

"Thank you little prince." Each of the musicians and dancers drank a drink, and they immediately became much more energetic and cooler.

"It's better that the little prince has a way! All this ice can be made!"

"It seems that the rumor is right. The little prince is a golden immortal descending to earth!"

"It's worth it for the rest of my life to marry the little prince."

......

The dancers felt the coolness in the hall and sighed, looking at Qin Yu's eyes full of admiration.

Xiao Nan didn't leave anymore, lying on the couch, drinking iced wine and eating iced watermelon, which was so cool, "Brother-in-law, you have to be strong, I won't change this day for a god!"

Qin Yu brought Shen Binglan a plate of iced fruit and a pot of iced wine, "Miss Shen, you can also relieve the heat."

Shen Binglan stopped, nodded slightly, and then poured a glass of iced wine.

She doesn't drink alcohol on weekdays.

But today is too hot and she feels so depressed that she no longer restrains her.

A glass of iced wine enters his throat, Shen Binglan feels more comfortable and cool.

She looked at the ice cubes all over the room and couldn't help but sigh.
Chapter completed!
