Chapter 1692 Done

"Haha, enough is enough. If it's not enough, you can tell Dad, and Dad will do more."

"Hmm!" Zhao Yuner responded.

Zhao Yuner polished the wooden planks on the ground first, then took out the nails and used a small hammer to nail the planks together.

It took an hour to finally make a wooden box.

Zhao Yuner deliberately added a few more layers around the wooden box to make the box more airtight.

As for the inside of the box, Zhao Yuner made some more paste and sealed it with some sand, so that the box would not be ventilated. Putting ice cubes in it won't melt so fast.

The box is not big or small, and you can put a lot of vegetables in it. There is a lid on it, just put it on.

Zhao Wenhua and Liang Jinqiao stared at it, seeing that Zhao Yuner had been working on it for a long time, and finally only got one box out, which made him even more confused.

"Could it be that storing leftovers in this box will keep the leftovers from going rancid?" Liang Jinqiao couldn't help but asked.

Zhao Yuner was amused by Liang Jinqiao, "Of course not! Mother, don't worry, you'll find out later! Haha!"

Liang Jinqiao responded, "Haha, okay, mother, wait!"

Zhao Yuner took the box and went outside to bask in the sun. The sun was shining on this hot day, and after a while, the paste on the box dried.

Zhao Yuner looked at it, and began to take out the saltpeter, and got some ice cubes out.

Thick ice cubes were broken and spread in the box.

Zhao Yuner then took the lid to cover it, and found the broken quilt that was not needed for the bed and came out.

"Father, mother, that's it!" Zhao Yuner said with a smile.

Liang Jinqiao and Zhao Wenhua looked at each other a few times, "Isn't this ice cube not easy to melt when it's inside? It's a hot day, still covering the quilt, doesn't it melt faster?"

"Yeah, girl Yun'er, do you store the ice cubes overnight? Even if you put the food in it, I don't think it will be stored for too long."

"It's waiting for the ice cubes to melt, and the inside is not so cold, and the food will be sour again!"

"Girl Yun'er, are you sure this is true?"

Zhao Wenhua and Liang Jinqiao said one sentence after another, and they didn't seem to believe that the box would be so magical.

If you put ice cubes in it overnight, it will definitely melt into water in a while.

"Mother, you don't know this, right? Covering the quilt not only won't make it melt, but it will make it melt more slowly!"

"This... how could it be!" Liang Jinqiao muttered.

"This quilt has a thermal insulation function. It's cool inside, and the cold air will be fixed. It's not easy for the hot air from outside to get in." Zhao Yuner explained.

"Is that so? Can that really be saved overnight?"

Zhao Yuner nodded, "It should be possible! As long as one night has passed, we can continue to get some ice cubes in the next day. If the vegetables are placed in it, they will definitely not be spoiled."

"Then let's try it tonight!"

"OK!"

Zhao Yuner is still very confident in the simple refrigerator she made.

Once this refrigerator is made, I can make a few more later, and send one to the Mulan family, and their family will definitely be able to use it.

Seeing the simple refrigerator made, Zhao Yuner couldn't wait to make something like herbal tea and put it in.

In this hot day, it is easy to get heatstroke, so it would be nice to get some iced mung bean soup.

The last time she went to Yangcheng, she bought a lot of mung beans and came back. They haven't cooked yet. I can cook some today for everyone to try.
