Lady, your space is blown up

Chapter 195 We Got Rich, We Got Rich!
What can this fire nitrate be used for?
Madam Jing naturally couldn't guess it, so she sent someone to Qingxi Town to keep an eye on Jing Qingrong and Su Liuer.

The people she sent arrived in Qingxi Town on the same day as the people who transported the fire nitrate.

Su Liu'er was going to do an experiment of making ice with fire nitrate, so she was closed for half a day and didn't open the door in the morning.

The backyard of this shop is big enough, Su Liu'er asked someone to build a pond with bricks and stones, which was as high as her knees, and asked Dali Xiaoli to bring back the iron box made by the blacksmith.

Jing Qingrong and Qingfeng took people to transport the fire salt to the shop. There were five boxes in total, all of which were filled with waterproof oil paper and wrapped tightly on the outside.

After putting down the nitrate, Jing Qingrong paid out the person who transported the nitrate.

"Now, can you tell me what these fire nitrates are for?" Jing Qingrong asked Su Liu'er.

Su Liu'er smiled mysteriously at him, and said, "It's better to tell you with your own eyes, and you'll know later."

Everything was ready, she began to experiment with making ice with saltpeter.

Because it was an experiment, Su Liuer didn't use the pool directly, but took a wooden basin.

She put the iron box containing water in the center of the wooden basin, then poured water into the wooden basin, the water level was lower than the edge of the box, and then began to put fire nitrate into the water in the wooden basin.

Because I don't know how much fire nitrate is needed, so she gradually increased.

A circle of people around were staring at it, and they still don't understand what Su Liuer is doing now.

All I saw was that she had been setting fire to the water.

These fire nitrates are not cheap, so let her put them directly into the water, and once they are in the water, the fire nitrate will melt into the water, so it will be wasted?

Everyone is frowning very puzzled.

However, Su Liuer continued.

This is a process from quantitative change to qualitative change. When the fire salt dissolves in water, it will absorb a lot of heat. If enough heat is absorbed, the water in the wooden basin and iron box will condense into ice.

Suddenly.

"Brother, look!" Ying Li exclaimed.

What did he see in this blue sky?Why is the water slowly changing?Is this going to freeze? !

Once you start changing, you will continue to change.

Su Liuer continued to add fire nitrate to the water, gradually the water in the wooden basin outside had condensed, and the water in the iron box was also condensing visible to the naked eye.

I do not know how long it has been.

Because everyone was dumbfounded looking at the scene in front of them, and felt that time seemed to have become extremely slow, feeling a little dazed.

"It's frozen! The water is frozen!" Ying Li was the first to bluff, and went up to touch it.

Su Liu'er didn't stop her, and immediately after that, both of them stepped forward to touch the successfully made ice cube.

Everyone was so shocked that they couldn't believe it, and they all suspected that something was wrong with their eyes and hands.

Ying Li stretched out his hand and squeezed Ying Li, the pain was so painful that Ying Li screamed at him to believe that he was really not dreaming!

"Boss! You are too powerful! Could it be some kind of magic technique? You can't be a witch!"

Su Liu'er stretched out her hand and tapped Yingli's head, and said angrily, "You are the witch, you are so godlike."

Jing Qingrong on the side pulled Su Liu'er, and said to her with an extremely excited expression: "This is ice making! You actually made ice! Do you know how much money you can make?! We are getting rich, getting rich!!! "

Jing Qingrong was so excited that he opened his arms to embrace Su Liuer.

"Master! Men and women can't kiss each other!" Qingfeng pulled Jing Qingrong away suddenly, so fast that he almost dragged his son to the ground.

　The fourth update is over, see you tomorrow~
　　Reminder of the day: Vote!

　　I checked the information on the method of making ice with saltpeter, but there are different opinions. What I wrote is a more reasonable method that I think is more reasonable, and the party should avoid it.
　　The seasons change, cuties, please pay attention to your health, Jiu'er has been hit by the virus...
