Knock knock! ”

Ye Feng was sweating and tinkering, he had recently found a way to pass the time when he was bored, and that was to carve wood carving.

Yes, that's right, carved wood carving!

As for his craftsmanship, Ye Feng said that he was still a little talented, of course, when he was naughty when he was a child, he carved a little doll on the desk with a knife.

"NND, it's so hot, if only I could have a popsicle!"

Ye Feng was also thinking in his heart.

But then remembering that popsicles are a fantasy in this era, he smiled self-deprecatingly and continued to carve.

As he was secretly arguing with a piece of wood in front of him, Ruhl walked up to him with a bag of animal skins.

"Ye Feng!" He shouted.

Listening to the voice, Ye Feng knew that the person who spoke was Luer, so he said without looking back: "What are you doing?" ”

When he spoke, the movements of his hands did not stop.

"We found something strange during construction, would you like to take a look?"

"Put it there first, I'll see it later!" Ye Feng was still headed, and he didn't reply, and continued to be busy with his business.

Seeing this, Ruhl was curious, and quickly stretched his neck to look over.

At this moment, I don't know what the reason is, maybe it's too much force, maybe the wood is too brittle, and Ye Feng finally carved it out, and it can barely be seen that it is a human arm, and the arm is suddenly broken.

Ye Feng was stunned for a moment, yes, failed again.

He threw the tool away and decided never to touch it again.

Taking the animal skin bag that Ruer had put aside, Ye Feng opened it and asked, "What is this?" ”

Although he wanted to know what he was doing here, Ruhl immediately replied: "I don't know what it is, it will emit cold air, which is what I feel most strange." ”

"Coming out of the air?" When Ye Feng heard this, he also became interested in what he was wearing in this bag.

When his eyes fell on the contents of the contents, he couldn't help but be surprised.

It was so familiar to him, so familiar that it could be said to have been deeply embedded in his bones.

So he hurriedly said: "When the cold air comes out, did you pour water on it?" If I'm not mistaken, it ended up frozen. ”

The next thing was that Lu Er felt very surprised, he didn't say these things from beginning to end, how did Ye Feng know?

However, thinking of his identity as a wise man, he did not continue to dwell on it, and quickly replied: "Yes, we poured water on it, and then ice came out again!" ”

Yes, this thing is right!

Ye Feng snapped his fingers and said, "You go and scoop a bowl of water, come over with a basin of water!" ”

Lu Er was stunned for a moment, not understanding what Ye Feng was doing by himself, but he still did it.

Soon, a bowl of water and a large basin filled with water were placed on the table.

Ye Feng put the bowl of water into the large basin filled with water, and then he grabbed a handful of the white object from the animal skin bag, and said to Luer: "Look, now is the time to witness the miracle!" ”

After saying that, it was like the kind of white object in his hand that was sprinkled into a large basin of water.

The moment the white object touched the water, a large number of bubbles were released, and a trace of cool air was gradually coming.

Then, Ye Feng kept changing the big pot and holding this white object.

After repeating this repeatedly, it didn't take long for Ye Fengyan to say in that bowl of water: "How is it, amazing, right?" ”

Luer's attention just now was attracted by Ye Feng's action of putting the white object into the large basin, and he didn't notice the change in the bowl of water.

But when he turned his gaze to the bowl again, the expression on his face changed instantly, his eyes widened, and his open mouth seemed to be able to stuff two eggs.

He looked at the bowl, and only felt that his brain was blank, and it was difficult to attach it to the shock, and he couldn't turn his thoughts for a long time.

In the end, he almost lost his footing, and after quickly stabilizing himself, he pointed to the bowl and said in a trembling voice, "This...... What's going on? It was still a bowl of water just now, how can it ...... How did it turn into a lump of ice in a few moments? ”

Ye Feng smiled, took the bowl from the basin, the cold feeling made him feel a burst of coolness, and said, "Actually, there is nothing strange about this!" ”

Pointing to the leather bag, he said, "The greatest credit is to that thing, if you do what I just did, you will make ice cubes!" ”

"Really?" Ruhl expressed great disbelief that as an ordinary person, how could he, as an ordinary person, transform into ice cubes out of thin air on a hot day?

So he didn't believe in evil and brought another bowl of water, and did it again according to Ye Feng's actions just now.

In the end, he got a bowl of ice.

Trembling and holding the bowl with ice, he couldn't believe that he had done such a miraculous thing.

When he looked at the bag of white things again, his eyes revealed the look of the peerless treasure he had seen.

"Ye Feng, what is this? How does it turn water into ice? Ruhl hurriedly asked.

Ye Feng said: "This thing is called saltpeter, it is non-toxic, it is edible, and it is not harmful to the human body. As for the principle, it absorbs a lot of heat when it dissolves in water, which can reduce the temperature of the surrounding water until it freezes! ”

Then he explained succinctly, temperature and sublimation and condensation, as well as the concept of solidification.

After listening to Ye Feng's explanation, although Ruer still felt the fog in the clouds, he understood that it was not a phenomenon caused by something unclean. As long as an ordinary person masters the right method, he can also conjure ice out of thin air in the summer.

Just when he was thinking so in his heart, he suddenly saw Ye Feng's next move, and he couldn't help but be stunned.

I saw Ye Feng holding the bowl of ice, coming to his mouth, clicking a bite, biting a piece, and chewing it in his mouth.

looked at Ye Feng blankly, and after eating a bowl of ice, he said hesitantly: "Ye Feng, are you okay?" ”

He thought that something was wrong with Ye Feng's brain.

Ye Feng chewed the ice, rattled and said, "Me? It's okay, what's wrong? ”

"That'...... What about this ice ......"

"Oh! That's what you're talking about, it's okay, it's cool to eat, why don't you take a bite too? ”

Ruhr still couldn't stand such "advanced thoughts", so he hurriedly waved his hand and said, "No, no!" ”

It's not like he hasn't eaten ice before, and in the winter, he once looked fucked, picked up a piece of ice by the river, put it in his mouth and bit it, and the tingling cold he still can't forget.

"Tsk, let's take a bite, it's really comfortable to eat!"
