Thinking about it, I haven't eaten ice cream for a long time. Not to mention ice cream, I can't even eat popsicles.
I miss you so much...
"What are you going to do?"
When Gu Jin saw Liu Zheng's smile, he became extremely angry!
How long has this happened and you can still laugh!
hateful!
The Christmas ceremony is tomorrow! Do you really think that if you win the war, no one will care about this ceremony?
Too......
This guy looks quite handsome, but he is a war maniac! War maniac! Gu Jin has lived in luxury since she was a child, but he is an anti-war element! Liu Zheng didn't want to deal with him, but now she hates him even more
.
Liu Zheng chuckled: "I told you, I want to make ice. Congratulations, Miss Gu, you will be the first person in the Longyan Dynasty to eat ice cream."
"close the door!"
Liu Zheng suddenly shouted.
Bang, bang, bang.
The men of the Liangzhou Army once again locked the door of the quarry tightly! Gu Jin was shocked when he saw it, and his face turned pale: "You, you, you, you want to kill people and silence them? Come here! Liu Zhizhou wants to
Killing!"
"He's going to run away and kill people and silence them!"
Liu Zheng didn't bother to pay attention to her at all.
He waved his hand.
Soon, several Liangzhou soldiers brought over a large pot and a small pot. They first placed the big pot on the ground, and then placed the small pot in the big pot. Then they placed a large amount of raw saltpeter in the big pot.
In the basin.
Gu Jin watched eagerly.
Deng Wenhui also widened his eyes.
The government officials also watched one by one.
Making ice?
How to make it?
These days, they have been collecting saltpeter here, buying pots and barrels, but they just don't know how to make ice with these things. At this time, Liu Zhizhou is finally going to put it into practice, how can they not be curious?
Liu Zheng looked at the proportion of saltpeter in the big basin, nodded, and then ordered a few Liangzhou soldiers to pour water into the basin.
This is the famous saltpeter ice.
What is saltpeter? The chemical name is sodium nitrate. When it dissolves in water, it absorbs heat, lowering the temperature of the water, causing the water in the small basin to cool down quickly and form frost.
And saltpeter was not difficult to find in ancient times.
Whenever the air is crisp in autumn, saltpeter is usually in the shape of a crust or salt flower, covering the corners of the ground, which is the so-called ground frost. Sweep up the nitrate-containing soil, place it in a bucket, add water to soak it, and filter it.
By boiling or drying the filtrate, saltpeter crystals can be obtained. Of course, there is also the most convenient way, which is raw saltpeter. In ancient times, it was originally a medicinal material and could be purchased in pharmacies.
This is why, in the past few days, Liu Zheng has been staying in the quarry. On the one hand, he asked Deng Wenhui to purchase raw saltpeter in the drugstore. On the other hand, he asked people to collect a large amount of saltpeter in the quarry.
"Hahahaha, is that it?"
Seeing what Liu Zheng did, Gu Jin couldn't help laughing.
The government officials who were forcibly brought to help could not help but cover their mouths and suppress their laughter.
That's it?
Busy here and there, treating them like donkeys, and this is the result?
Liu Zheng patted his forehead: "I almost forgot!"
He quickly poured the watermelon juice he had prepared into the small basin.
Everyone in the audience laughed loudly when they saw his mysterious operation.
However.
soon.
They couldn't laugh anymore.
The first person whose laughter stopped abruptly was Gu Jin.
Beijing has been unbearably hot these days. Therefore, any slight drop in temperature around you at this time will be felt very obviously. What surprised Gu Jin was that there was a hint of coolness coming from the direction of the water basin Liu Zhizhou had created.
Her laughter stopped.
Deng Wenhui also started to be stunned.
The government officials who were waiting to see the joke were also dumbfounded.
