"The key to making this ice is actually the saltpeter we just bought from the pharmacy. When this thing is mixed into the water, it absorbs a lot of heat, which condenses the water into ice cubes......"

Although Cheng Chubi and the three of them seemed to understand whether they understood or not, this did not hinder the interest of the three of them in the experiment.

Immediately, the basin of ice cubes in the water tank was taken out, and Cheng Shi farts and put another basin in it.

The three of them happily started to work as ice porters......

People were startled, and Liu Changqing, who had just fallen asleep with great difficulty, was shocked.

Looking at the three people who took out a block of ice from the tank at one time, and a block of ice from the tank at the other, the three people could hardly believe their eyes.

Just when the three of them were working happily, Qiao'er suddenly pounced, like a hen guarding food, and opened her arms to protect her own water tank.

"This vat belongs to our family, you can't move-"

Cheng Chubi and the three of them, looking at this little girl who was nervously protecting her water tank, couldn't help laughing and couldn't help laughing.

Liu Zi'an was also amused by this girl.

stepped forward and explained for a long time before she convinced this girl that it was not her own tank that became a god tank, but because her brother put something that could make ice in the tank.

The first time I saw ice cubes in the summer, the little girl scratched her hand excitedly, and wanted to deduct a piece to eat, but was blocked by Liu Zi'an.

Although the water in the copper basin does not come into contact with saltpeter, these ice cubes are frozen in cold water, and you will not have diarrhea if you eat them.

got up and went to the kitchen to pour a basin of cold boiled water and refreeze a basin, which was considered to satisfy the little girl's wish.

Looking at the little girl, carefully stuffing the ice cube into her mouth, and happily squinting her eyes into a crescent moon, Liu Zi'an was suddenly full of a sense of accomplishment.

"This is pure ice, wait for tomorrow, my brother will buy something and make you ice cream-"

I don't know what ice cream is, but since my brother said it, it must be something more delicious than ice cubes!

At the cost of three pieces of ice cream, Liu Zi'an finally managed to stop the little girl's enthusiasm for eating ice cubes.

Put two pots of ice in the parents' room, and two pots of ice in Qiao'er's room.

The stuffy room suddenly became much cooler.

The remaining ice cubes were brought to the potato field by Cheng Chubi and Li Siwen in wooden barrels.

"So much!"

When Cheng Yanjin saw the ice cubes in this bucket, he couldn't wait to get into the bucket, but he was hot just now.

"I didn't expect you to have such a big ice cellar in the middle of nowhere—"

Cheng Yanjin took the time to sigh while holding a piece of ice cube and rubbing it on his face.

"Where did you get the ice cellar, it's all the three of us, no, it's the four of us-"

Cheng Chubi couldn't hold back the smugness in his heart anymore, and said a little sneeringly.

"Didn't you rob someone's ice cellar?"

As soon as he heard Cheng Chubi say that he did it himself, the movements on Cheng Biting Jin's hand suddenly stopped. Raised his head, staring at his troublemaker with unkind eyes.

There is a murderous aura!

This familiar aura made Cheng Chubi's thoughts suddenly disappear, and he jumped behind Liu Zi'an with a bang. Hurry up and tell the difference.

"I didn't rob it, we produced it ourselves!"

"Produce it yourself? You think it's a cub! Bastard, why don't you fly, you think you're a god-"

Cheng Yanjin was thrown into the barrel by the ice cube, and subconsciously scolded, but as soon as the word fairy came out, he suddenly gasped.

"Zi'an, did you get it again?"

"Small means, small means, most of these are actually the ...... made by the three of them"

In order to avoid the old guy's chattering questions, Liu Zi'an sold the three of them without hesitation.

Sure enough, as soon as Liu Zi'an finished speaking, Cheng Biting Jin reached out and fished Cheng Chubi over. Where did Cheng Chubi dare to be a demon in the hands of his father, and he was cleaned up after a while.

got the exclusive secret recipe, and Cheng Biting Jin was not afraid of the heat.

One person kicked everyone back to Liu Zi'an's house. When the three of them came back from home with a water tank and buckets, Cheng Yanjin experimented with great interest.

This old man had been tossing and turning for most of the night, almost turning his tent into a fortress of ice, before he stopped contentedly.

"Go back to the old man to pay, let's get an ice-making workshop in Chang'an, get some change to spend——"

This can be had, Liu Zi'an agreed without saying a word.

Isn't that what you came for when you chose to make ice today?

It's crossed, it's systematic, don't say anything else, let's get a little money to change the living conditions of the family.

"You're still in school, you don't have to worry about things in the workshop, just study honestly, just grow good potatoes seriously, don't worry about the rest, you just wait for the money-"

reciprocated the favor, Liu Zi'an gave such a big credit to his son, of course he had to take care of this child.

Cheng Yanjin turned over, changed to a more comfortable position, glanced at Li Siwen and Qin Huaiyu, who wanted to stop talking, and couldn't help but laugh and scold.

"Manly man, what's the matter, just say happily, look at your little talent, isn't it just an ice-making workshop, with my uncle and mine, can you be without you?"

"Yes, yes, yes-Uncle Cheng, you are righteous, and this has always been the case!"

Li Siwen blushed, gave Cheng Yanjin a thumbs up without any bottom line, and was kicked aside by Cheng Yanjin.

"Get out, don't pour ecstasy soup on Lao Tzu-"

Li Siwen grinned and found a place to lie down and sleep.

It is rare to have such a cool place, Liu Zi'an quickly found a place to lie down.

Go to bed early and wake up early, and tomorrow I have to go to the city early to run and buy something to make ice cream for the girl.

Thinking about things in his heart, Liu Zi'an himself didn't know when he fell asleep.

Just when Liu Zi'an, Cheng Yanjin and others were tossing ice cubes in the potato field, Dr. Yu, who had been busy for a day, finally returned to his home.

However, before he could take off his coat and breathe a sigh of relief, Lu Yan'er, who had been waiting at home for a long time, rushed over and knelt on the ground.

"Father, help—"

Zhang Liang's eyebrows were instantly twisted together, and he had the impression that the bewitching woman in front of him should be the concubine of his righteous son and eldest grandson, look at this appearance, isn't something big wrong?

finally waited for Zhang Liang, and Lu Yan'er's heart finally let go.

Sobbing and choking, he added fuel and vinegar to what happened, and Zhang Liang suddenly became angry.

"Little brute, you deceive people too much!"

The front foot just broke the head of his own son, and the back foot took the nest of his own son, and more importantly, he also snatched the birthday gift prepared by his own son, which is really unreasonable!
