Chapter 179 Brother-in-law, let's have a showdown with us!
Seeing Xiao Nan and Shen Binglan's expressions of disbelief.
Qin Yu smiled faintly, "What? Is it difficult to turn water into ice?"
Xiao Nan: "???"
Shen Binglan: "???"
Turn water into ice!
This is not a question of whether it is difficult or not, it is a question of unreality.
Xiao Nan's eyes widened and he said blankly: "Brother-in-law, are you sure you are not joking?"
He was talking.
"Your Highness, your well water."
Deng Bao had already brought in people carrying well water.
"Of course it's not a joke!"
Qin Yu said and looked at Deng Bao, "Eunuch Deng, go get some saltpeter for me. I will find it of great use!"
Saltpeter is a natural mineral that has appeared in this era. However, except for a small amount of processing and use as medicine, it has no other uses, so the amount of mining is not large.
"Saltpetre?"
Deng Bao was stunned for a moment, then said: "It's the young prince. I will go to the Imperial Hospital to get it for you."
Qin Yu said: "The Imperial Hospital is simply not enough. If you take people to dig in the western suburbs and bring him back with a few carriages, I will be of great use to you."
"Yes, young prince." Deng Bao responded and then left the hall.
He should do his best to do what Qin Yu asked him to do.
Xiao Nan listened and asked doubtfully: "Brother-in-law, why did you ask Deng Bao to dig saltpeter?"
Qin Yu smiled and said, "Of course it turns water into ice. Just wait and see."
Saltpeter?
Turn water into ice?
Xiao Nan really didn't know how to connect these two things together.
Deng Bao went to look for saltpeter, while Qin Yu and the others waited in the palace.
In this era, ice was a rare thing. In order to have ice to relieve the heat in summer, the Royal Palace even established the Ice Administration Department.
Ice is generally taken in winter and then stored in ice cellars and ice wells.
In addition to being used for indoor cooling, it also has the function of keeping meat and vegetables fresh, and can even be placed in water for direct drinking.
But no matter what method is used, ice is very precious in this era.
Only the royal palace and some nobles can use it.
But this year the weather got hot early and very hot, so the ice cubes were consumed very quickly.
It was just morning, and it was already extremely hot.
An hour later.
Deng Bao took people back to the East Palace.
Saltpeter was not a rare thing in this era. Truckloads of saltpeter were transported to the East Palace.
Qin Yu also sent people to find large wooden barrels and porcelain jars and put them in the hall.
After everything was prepared, Qin Yu started making ice.
"Come here, pour water into the bucket!"
Qin Yu was directing from the side.
Several little eunuchs poured well water into the big wooden barrels one by one.
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.
Afterwards, Qin Yu found a rope, nailed a net into the barrel, and then placed the porcelain jars filled with water one by one into the barrel so that the bottle mouths were exposed and would not be contaminated.
After it's done.
Qin Yu waved his hand and said, "Come here, put saltpeter in the barrel."
Then, several young eunuchs began to put saltpeter into the barrel.
The principle of making ice from saltpeter is very simple.
When saltpeter dissolves into water, it absorbs a large amount of heat, which causes the water to cool down and freeze.
However, saltpeter is poisonous, so Qin Yu put some porcelain jars with clean water in the barrel.
In this way, the ice cubes in the porcelain jar can be used for eating, and the ice cubes in the wooden barrel can be used for cooling. It is simply killing two birds with one stone.
As the saltpeter continued to be thrown into the wooden barrel, a large amount of heat began to be absorbed by the saltpeter, and the water in the wooden barrel slowly changed, and a hint of coolness slowly spread out.
"It's freezing! The water in the barrel is actually frozen!"
"Oh! It's amazing! It's amazing! The young prince is really amazing!"
"This...how is this possible!? Is the young prince an immortal descending to earth!?"
...
All the little eunuchs looked at the ice in the barrel, and they all opened their mouths in surprise.
They were really shocked by Qin Yu's magical methods.
Not to mention them, even Xiao Nan and Shen Binglan were so surprised that they couldn't open their mouths from ear to ear.
It's really a magical way to turn water into ice.
Xiao Nan felt the coolness emanating from the bucket, looked at the ice cubes in the bucket, and then looked at Qin Yu. He was dumbfounded and exclaimed: "Sister...brother-in-law, just show us your cards! What are you?"
It's not like gods descended to earth, you...you are a bit too ridiculous, how is this possible!?"
Shen Binglan stood next to the wooden barrel, her eyebrows condensed,
She could see that this was indeed not a trick, but real ice.
Can saltpeter freeze when put in water?
this......
Why has no one ever discovered this?
Qin Yu's face was light and the clouds were calm, "What kind of god comes down to earth and turns water into ice? Saltpeter dissolves in water and absorbs heat and freezes. This is called scientific means. This is called chemical reaction. Do you understand science?"
"Even if you let a dog put the saltpeter into a bucket, it can freeze."
Xiao Nan rolled up his sleeves and said impatiently: "I'll give it a try."
Qin Yu: "..."
After just saying that dogs are fine, he insists that he wants to try it. It’s really hard to persuade him.
Qin Yu said calmly: "You give it a try, anyway we need to make a lot of ice."
Afterwards, Qin Yu directed the little eunuchs to start smashing ice, put it into basins, and then placed it everywhere in the palace to cool down.
He bought a few more ice buckets and put the wine poured into porcelain bottles into the ice buckets to chill.
It was well past noon.
The decoration in the side hall has just been completed.
The air in the hall has also become much cooler, and there is basically no feeling of intense heat anymore.
Qin Yu summoned the musicians and dancers and rewarded them with wine, "Girls, drink a glass of ice-cold wine to relieve the heat. I will reward you."
Qin Yu drank all the fine wines collected by Emperor Wei and sent as tribute from the Western Regions during the previous dynasties.
They are not even qualified to drink on weekdays.
"Thank you, young prince." The musicians and dancers each drank a drink, and they immediately felt a lot more energetic and cooled down a lot.
"The young prince still has a way! You can make this ice!"
"It seems that the rumors are correct, the young prince is a golden immortal descended to earth!"
"Being able to marry the young prince will make this life worthwhile."
...
Feeling the coolness in the hall, the dancers all sighed, looking at Qin Yu with eyes full of admiration.
Xiao Nan didn't leave either. He lay down on the couch, drank ice-cold wine and ate ice-cold watermelon. It felt so good, "Brother-in-law, you have to be the best. I wouldn't change it for a god today!"
Qin Yu brought a plate of iced fruit and a bottle of iced wine to Shen Binglan, "Miss Shen, you can also relieve yourself from the heat."
Shen Binglan hesitated, nodded slightly, and then poured a glass of iced wine.
She doesn't drink on weekdays.
But it was too hot today and she felt very depressed, so she no longer restrained herself.
A glass of ice-cold wine went down her throat, and Shen Binglan felt refreshed and refreshed.
She looked at the ice cubes all over the room and couldn't help but sigh.
Sure enough, Qin Yu only did these things to make himself more comfortable.
