The best girl traveled through time and took the system to escape.

Ice, hehehe~

Song Nan was laughing like a fool before he even got the saltpeter out of the car.

Although she has a system that can directly exchange ice for it, it requires survival points.

This point of survival is like Song Nan's life, how can she be willing to spend it?

Making ice from saltpeter is very simple.

At that time, almost eight out of ten people knew about it.

Since she can get ice without spending any survival points, she is naturally very happy.

Song Nan moved the bag of saltpeter into his room and thought about what to do.

A large container and a small container.

Song Nan searched for a long time but couldn't find it.

Although their house was not bare, they didn't have much that could be used.

Now there are two rooms available for Patriarch Song and his family to live in. Although the piles of his own things are not cluttered, it is not convenient to add more things.

Song Nan looked left and right.

In the end, she fell in love with the large and small water tanks at home, and there happened to be some water in the big water tank.

But getting a small water tank into a big water tank is not an easy task.

Although she has space, putting the small water tank in and putting it out may not be able to safely put it into the large water tank.

Why enlarge the small water tank into the water tank?

Because the ice made from saltpeter is poisonous, it cannot be eaten directly.

Two water tanks are stacked on top of each other, and saltpeter is placed between the large water tank and the small water tank, so that the ice formed in the small water tank can be eaten.

After thinking about it, Song Nan entered the room with a face full of pain.

Let’s exchange the survival points for two plastic basins of suitable size...

Although the water tank is nice, it cannot be moved into the house.

Not to mention the third grandpa's family members in the courtyard, even the courtyard wall didn't block anything. It was just a wooden fence. People who stood outside and stood on tiptoe could see inside, and they didn't feel safe at all.

After entering the house, Song Nan carefully closed the door.

It was inconvenient to have other people living at home. If it was just his own family, Song Nan wouldn't bother to close the door.

However, Grandpa San and his family had no choice. They heard that Village Chief Zhang nodded and agreed that the Song people would go up the mountain to cut down trees and build houses.The burned wood will be moved away these days, and the trees will be cut down in the mountains in a few days. It is expected to be completed before the year.

Song Nan also asked Song's mother if their family should follow this path and rebuild the house together, but Song's mother was still a little hesitant.

The family does not have a stable income yet, Song Huai and Song Hao still have to study, Liu Qiaoer is still pregnant, and the family has not purchased anything for the winter or stocked up on food.

Each item requires money...

No, Song Nan is here to make money.

Song Nan placed a large and a small white plastic bucket on the ground and filled them with water.She stopped filling the water only after the water level in the big plastic bucket was equal to the water level in the small plastic bucket.

Afterwards, Song Nan kept adding saltpeter into the vat.

Before long, the water in the two plastic buckets turned to ice.

Song Nan carefully hung up the saltpeter from the large plastic bucket of ice and wrapped it in a small cloth.

This thing can be recycled!

The ice had formed, and Song Nan, who was close to the two buckets, felt that the surroundings were much cooler.

Song Nan, who was excited, directly exchanged it for a clean chisel and chipped out a small piece of ice.

Picking up the ice and putting it in his mouth, he felt a chill in his mouth.

The cold ice cubes touched his tongue and teeth. Song Nan was glad that he didn't cut too big a piece, otherwise his teeth wouldn't be able to bear it.

It was only a few days in August and it was still very hot in the south.

Although it wasn't as hot as when Song Nan and his group came from the north, it wasn't much better.

The only difference is that the south is close to the sea and has abundant water resources. It rains from time to time, so it won't suffer from drought like the north.

Song Nan estimated that it was around three or four in the afternoon. After several hours of exposure to the sun, it was very hot outside.

Her father was the only one killing chickens and plucking their feathers in the yard. Everyone else stayed at home or enjoyed the shade under the trees. Others, like Fang Peilan, went into the mountains to look for wild vegetables.

There are trees in the mountains to block the heat, so it is naturally not as hot as in the yard. You can also add some food to your home. People who have nothing to do are naturally happy to go up the mountains.

Song Nan took out his chisel and chiseled out many pieces of ice. Then he went out and brought in a large bowl and filled it with ice.

Then put the bowl of ice and the ice bucket in the house into the space.

He walked up to Song Youcai, made sure there was no one around, and whispered: "Father, open your mouth."

Song Youcai was plucking chicken feathers with the hot water that his family had put on the shelf after lunch, and he immediately opened his mouth when he heard this sound.

This has to be his daughter, not his grandson.

Otherwise, he would have thought that boy was going to stuff dog shit into his mouth. After all, Song Hao actually did this when he was less than two years old!

After a beating, he had a better memory and knew not to stuff dog shit into other people's mouths.

As a result, he stuffed it into his mouth!

Hey, it's all tears when I say more.

Hey?

what is this? !

After Song Youcai opened his mouth, his little girl stuffed a small ice cube directly into his mouth and helped him close his jaw.

The icy cold feeling suddenly made Song Youcai tremble!

After licking his tongue from side to side, Song Youcai was sure that this thing was ice!

I turned around to look at where my daughter was, but to my surprise, she was gone!

Song Nan is at the door of Song Huai's house at the moment.

Song Bai and Dou Xiaomei followed Fang Peilan up the mountain. Song Liu was reading medical books and taking care of Liu Qiaoer in the house. The task of looking after the child was handed over to Song Huai.

The two little guys were taking a nap now, and Song Nan guessed that her fourth brother had woken up.

After knocking on the door twice, I heard a sound inside.

Soon Song Huai came to open the door.

Song Nan entered the room with a smile and closed the door.

"Fourth brother, look what good things I have brought."

She raised her hand, and the big ice bowl appeared on the table where Song Huai was reading.

Song Huai's eyes widened!

He raised his hand to rub his eyes and looked closer. He thought he had been reading a book since he hadn't slept at noon and was dazzled!

"This! Ice?"

As a northerner, it is impossible for Song Huai to have never seen ice.

When he was studying at Luming Academy, some students from wealthy families could also use ice in the summer.But people dug very deep cellars in their homes. In winter, they dug large blocks of ice from the river and put them in the cellar. In summer, most of the ice had not yet melted before they could be used.

The south is no better than the north. The temperature in the south is always quite high.Even if you dig a cellar to store ice in the winter, not much will be left after it melts in the summer.

The ice in the south can be said to be priceless!

People who can store ice don’t even have enough for themselves, let alone give it away!

So where did his little sister get this bowl of ice?

Song Huai's surprised look made Song Nan happy. He felt a little regretful that he had come too soon, and he didn't know what his father's reaction was just now.

"Fourth brother, why don't you try a piece first?"

Song Nan took out a small piece of ice from the bowl and put it in his mouth.

Um~

It would be even better if we get some juice, milk tea, taro balls and beancurds, etc.!

Just as Song Huai picked up a piece of ice, he heard his father's voice coming from outside the door: "Nan Nan! Do you still have that thing?"
