Yipin County Magistrate: Start with invincibility

Chapter 474
"Aren't you too hot? I'm going to get something nice."

"Good stuff? What stuff?"

The little princess's eyes lit up, she knew what Qin Feng was capable of, and she could tell from Qin Feng's ability to fiddle with so many weird things before.

But although the things that Qin Feng worked on before are all magical, they are not particularly attractive to the little princess.

But what to do now is different.

Since Qin Feng has said that it is a good thing that can deal with the sweltering heat, it must be a very interesting good thing.

Thinking of this, she couldn't help feeling a little excited.

Qin Feng suddenly smiled: "Princess, wouldn't it be nice if we could eat ice in this sweltering summer?"

"Eat ice?"

The little princess jumped up all of a sudden: "Really?"

But she immediately lost her mind: "But, where is there ice around this Black Creek City?"

After coming to Black Creek City, although the little princess never said anything, Qin Feng also prepared 1 taels of silver for the little princess.

For Qin Feng, the meaning of the little princess to him is not just a friend who comes to seek refuge after being in trouble.

He is being targeted by the First Prince now, but it is not so easy for him to deal with the First Prince alone.

And there is also a little princess among the people that the eldest prince has to deal with, as long as the little princess is on his side, wouldn't he have an extra card in his hand.

It is precisely because of this that even though the current conditions in Black Creek City are not very good, he will still try his best to meet the material needs of the little princess.

At least when I need the little princess in the future, I can confidently say that I have entertained the little princess for so long.

But the little princess is not that kind of naughty person, and she doesn't spend much money on weekdays.

But she definitely has money, so she also searched around Black Creek City, hoping to buy ice around Black Creek City.

Of course, her plan to buy ice ended in failure, because there was no ice in the area around Black Creek City.

Seeing the lost look of the little princess, Qin Feng suddenly burst out laughing.

"What's wrong with no ice? We can make our own ice if we don't have ice."

When he said this, the little princess was naturally taken aback.

"Make your own ice?"

"That's right, it's such a trivial matter as making ice, how could it be difficult to get me."

"Really? That would be great."

The little princess jumped up excitedly and almost fell to the ground, but it was Qin Feng who quickly helped her up.

"Grandma, please slow down."

"What are you waiting for, let's make ice now."

"Don't worry, we must prepare first."

As Qin Feng spoke, he conceived in his heart.

The principle of making ice is very simple, that is, when saltpeter dissolves in water, it will absorb a lot of heat to achieve the purpose of cooling water.

But what Qin Feng wanted was that kind of ice.

The steps of making ice with saltpeter can be divided into three stages, water at normal temperature - cooling to zero - freezing water at zero temperature.

The first two steps are not difficult, but the most difficult is the third step.

If you want to turn ice water into ice cubes, you need to break the zero-degree boundary, but this boundary is so easy to break.

To turn ice water into ice cubes, a large amount of saltpeter needs to be dissolved.

However, Qin Feng immediately thought of a solution. As long as there is such a piece of ice, it can quickly help the ice water break through the critical point and crystallize into ice.

But around Black Creek City, where can he find ice?

If you want to find ice, you still have to go to Bincheng.

Qin Feng scratched his head, it seems that the plan he had just thought about eating shaved ice probably failed, but without shaved ice, drinking ice water is also a very good choice.

Under the leadership of Qin Feng, the little princess and Qin Feng came to the Black Creek City one after the other, the open space where Qin Feng had previously made mercury lysate.

All the equipment here was taken away by Wei Quanyou. As for the waste liquid, Qin Feng asked someone to dig a cellar, and then spread the four sides with clay, set it on fire and solidified it, and then poured all the waste liquid into it.

These waste liquids cannot be dumped at will, even if the amount is small, but the toxicity brought by these waste materials is very high. Qin Feng plans to wait for a less busy time to do a harmless treatment of these waste liquids.

Ever since Qin Feng made so many things in one go, he has gradually become obsessed with the pleasure of creating all kinds of things out of thin air through chemical knowledge.

So he also had an idea to transform this warehouse into his own laboratory.

Of course, this idea just surfaced in his mind, and he hasn't started to act yet, so the warehouse is empty.

However, using saltpeter to make ice does not require any complicated supply and demand.

Qin Feng found several large and small glass tanks and filled them with water.

The principle of using saltpeter to make ice is very simple. When saltpeter dissolves in water, it will absorb heat. However, the ice water or ice cubes produced are also a mixture of water and saltpeter. It cannot be drunk directly, but Qin Feng can use another container to make ice. Store drinking water.

"AMAZING!!! How on earth is this done?"

The little princess looked at Qin Feng in surprise. She saw Qin Feng sprinkle saltpeter powder into the water. After a while, the water in the big glass tank and the other small glass tank became icy cold. Yes, there was even a layer of white mist outside the container.

It was the first time he had seen such a scene.

Qin Feng chuckled: "If I tell you that I am actually a fairy and can change spells, would you believe me?"

"I believe."

The little princess nodded seriously, and even looked at Qin Feng with a bit of admiration in her eyes.

"Uh……"

This time, Qin Feng was stunned first.

In fact, what he doesn't know is that in the entire Black Creek City, his image in the hearts of the people in Black Creek City is no longer even a person, but a bit more mythical.

In fact, if you think about it carefully, from Qin Feng's terrifying fighting power, coupled with his profound knowledge, which one of these things can ordinary people possess?

Even if Qin Feng is not a god, he must be the reincarnation of a god.

"Otherwise, how do you explain that the water will become icy cold?"

"Silly girl."

Qin Feng couldn't help laughing: "Actually, I don't know any spells at all. I'm just using some means. Now I'm using physics knowledge to make the water cold."

"In addition to physical knowledge, there is another means called chemical knowledge. One of them is macroscopic and the other is microscopic. They complement each other and constitute the essence of this world."

He looked so engrossed that the little princess felt bewildered.

But she shook her head: "It doesn't matter what you are talking about, you really can change spells, right?"
