See?

What to see?

Zhou Jingxian stared at the large and small copper basins set together inexplicably.

Closer, you can smell the slightly choking smell of crushed saltpeter.

She was even more confused.

I thought that the recipe that Ning Wuxian said was like steaming wine, which required a special still.

I didn't expect it to be just a few copper basins.

Saltpeter does not change except for mashing...... What the hell is he trying to do?

"Lord Xian, you squat farther away."

lest it freeze you for a while.

Ning Wuxiao snapped and beckoned to Shen Youchu, who was still busy.

"Miss Shen, don't be busy, come and see."

"And Miss Ji...... You're far enough away, but not so dangerous. ”

After greeting the three of them.

Ning Wuxian asked Yun Fei to find a thin stick with the thickness of his fingers, holding a small copper basin in saltpeter with his left hand, and carrying the copper pot with his right hand.

"I'll get the stick."

Zhou Jingxian took the stick handed by Yun Fei, the distance did not change, but she stretched out her arm.

Seeing this, Ning Wuxian couldn't help but sigh: long arms and long legs are practical.

"After I pour the water in, when I ask Lord Xian to stir it, you can stir it lightly a few times to let the water flow."

After speaking.

Ning Wuxiao looked around and smiled mysteriously.

Next, it's time to witness the miracle.

"Pour water."

Bang Bang Bang Bang ......

The water in the kettle is poured into the large basin through the spout.

With the infusion of water, Zhou Jingxian, who was closest to the basin, suddenly felt a cool breeze coming from the copper basin.

She thought it was the mountain wind blowing in the early morning, and she didn't think much about it.

"Stir."

Hearing Ning Wuxian's order, she hurriedly stirred the saltpeter in the large basin with a wooden stick.

Not much.

When saltpeter fuses with water, the clear well water becomes slightly cloudy.

This is an impurity in the raw saltpeter ore.

Zhou Jingxian was about to ask if she wanted to remove the impurities and reuse them, when she heard a subtle "click" sound.

The chill on her face made her shiver.

Looking at Ning Wuxian, who was closest to the basin, his fingers holding the small copper basin seemed to be a little blue.

What's going on?!

Zhou Jingxian was taken aback, and was about to ask Ning Wuxian if Fang Zi had failed and was not feeling well.

I heard Shen Youchu exclaim: "Jingxian, Jin'er, have you heard any strange movements?" ”

"Yes."

Ji Jin hurriedly put a few strokes on the paper and recorded them.

"It seems to have the sound of something brittle cracking."

It's like the breaking of thin ice in winter.

Ji Jin added another sentence in his heart.

Shen Youchu hurriedly nodded: "Yes, yes, that's the voice, Jingxian, did you try too hard to crack the copper basin?" ”

Wronged.

Zhou Jingxian couldn't help but explain: "Youchu, if you don't get closer and take a closer look, I'm afraid that the saltpeter water will splash on Mr. Ning, so I didn't use any force at all." ”

"I can testify."

Ning Wuxian, who had been staring at the lid of the copper kettle, spoke out to defend himself, which made Zhou Jingxian breathe a sigh of relief.

But then, she asked curiously, "Mr. Ning, what is cracking?" ”

"Ice."

Ice?!

Zhou Jingxian and the three of them looked at each other, and their eyes were opened to the maximum to look at the saltpeter water in the copper basin.

No ice.

And this is a solar term of several volts, how can there be ice?

"I seem to have misremembered one thing, I forgot to get insulation, I should dig a cellar."

Ning Wuxian was glad that Zhou Jingxian's family had a mine, and there was a lot of saltpeter.

Otherwise, he would be embarrassed if he couldn't freeze at this time.

"Ning Gongzi, where is Bing?"

Although Shen Youchu suspected that Ning Wuxian was teasing them, she was still very cooperative.

What if there is ice at all?

Although it is cool on the mountain, if there is ice, you can eat chilled fruits.

It's a pity that the edible ice cubes stored in winter are too expensive, and the Ning family is reluctant to use them at all, otherwise, she will still be able to eat crushed ice fruits.

Ning Wuxian saw that Shen Youchu was so greedy that he began to bite his lip, and said in his heart: According to the movement just now, the icing should have been successful.

Forget it, don't wait.

"I'm going to open the lid."

There was a meaningless notice.

Ning Wuxian opened the lid of the copper kettle.

Suddenly, a cool air slapped on his face, making his hairs stand on end.

Cool!

Ning Wuxian looked at the ice ballast in the basin, and his heart was very beautiful.

Immediately, after the freedom of perfume, he achieved the freedom of ice.

And Zhou Jingxian and the three of them, seeing with their own eyes the half basin of water in the copper basin, actually formed fine ice ballast at this time, and suddenly felt like they were in a dream.

"Mr. Ning, this ...... Is it really ice? ”

Zhou Jingxian was wondering if she had just looked away for a while.

And Ning Wuxian is also a folk juggler, and he can replace the water in the small copper basin with ice while people are not paying attention.

But.

The ice ballast in the basin is very thin, and if you prepare it in advance and put it into the basin, it is likely that it has already turned into water by this time.

Besides.

Except for her, Youchu and Miss Ji have been staring at the movement in the basin, if someone really exchanges water for ice, it is impossible for no one to find out.

What the hell is going on?

Not only did Zhou Jingxian not understand, but Shen Youchu and Ji Jin also rubbed their eyes to confirm that they were not dazzled.

Except for Ning Wuxian, even Yun Fei, who had been following Ning Wuxian and had been watching since Ning Wuxian started tinkering with saltpeter, didn't understand why half a basin of water at the good end had actually turned into half a basin of ice ballast.

It was obviously summer when he was there, and he was a little hot in a thin gown.

Why does water freeze?

Ning Wuxian saw that everyone had witnessed the miracle on their faces, and they still had an expression of disbelief, which was quite a sense of accomplishment.

Shocked.

In fact, saltpeter ice was in the world he lived in in his previous life, when gunpowder was invented at the end of the Tang Dynasty, I don't know who used it to make ice cream.

And in this era, there is no gunpowder, and naturally there is no ice-making technology attached to the gift, so that he can pick up a leak.

"This ice is not very good, add more saltpeter for a while, anyway, saltpeter can be reused by cooling crystallization method when you turn back."

Ning Wuxiao made an excuse for his failure that others couldn't understand.

Then pinch a piece of ice ballast and stuff it into your mouth.

It melts in your mouth and slides into your stomach, and the coolness from the inside out is really refreshing.

Shen Youchu saw that he reached out and took a piece of ice ballast and ate it, and then boldly pinched a piece and stuffed it into his mouth.

Not......

The ice water after melting is clearer than the ice cubes that she tasted ten taels of silver and a pound of pure ice.

Thinking that this pot was filled with freshly drawn well water, which was not frozen in winter until it was put out in summer, it was normal to have such a taste.

"Mei Xiang, go pick some peaches and taste them with crushed ice."

Mei Xiang stared at the crystal clear ice ballast, and went to pick peaches step by step.

I only hope that in the future, Ning Gongzi can conjure up more ice cubes, and they, who are current people, can also enjoy their mouths.

Shen Youchu is not a person who eats alone.

She pinched two more pieces of ice, one left and one right, and stuffed them into Zhou Jingxian and Ji Jin's mouths.
