Chapter 1625

Make ice.

In the previous words, it was actually very simple. It was to throw saltpeter into the water, and then let it volatilize fully, so that the heat generated during volatilization can quickly extract the heat from the water, resulting in the natural reaction of water condensing into ice in a very short time.

of course.

If you throw a saltpeter as big as your palm into the river, ha ha.

That can only be ha ha.

There is also a degree.

That's the problem of proportion. Just like when Zhang Feng was on the mountain, Zhang Feng threw at least a fist sized saltpeter into the large water tank, and coupled with rapid stirring, this enabled a tank of water to reach the critical point of freezing in a short time.

In future generations, almost everyone will.

But where is this?

This is in Datang!

And it is also the most prosperous society of feudal superstition.

Last time, Chen Tieniu asked Zhang Feng about it, but Zhang Feng still didn't want to tell others by this forced means.

This is simply a force artifact at your fingertips.

Especially after obtaining the authority to manufacture gunpowder, saltpeter, sulfur and other things controlled and strict by the government are constantly obtained from energy sources, so Zhang Feng can get this thing from himself.

At this point.

Zhang Feng looked at people's faces in different states and couldn't help but lose the depressed color in his heart.

Especially seeing Cui Yingying's wide mouth and staring at the beads, she felt hungry and worth it!

So far, Zhang Feng, the woman, doesn't know why she should make it so difficult for herself to make a fool of herself on such an important occasion. Originally, Zhang Feng didn't want to see a woman, especially a yellow haired girl who only looks about 17 or 18 years old.

However, people live in one breath, which is forced to this share. If he doesn't show his hand today, he will lose not only Zhang Feng's personal reputation, but everything!

Including life!

Previously, Zhang Feng guessed that this person may have an old relationship with yu'er, but at this time, it seems that she still knows a lot about the "Zhang Feng" in the Phoenix Ridge period, so it's not easy.

This can't help but make Zhang Feng think of a person he heard Lao Yu once said when he was in the mountain!

That's the cousin who came with the engagement

But these two don't seem to be the same person, do they?

This is what worries Zhang Feng most.

If this is really Cui Yingying, Zhang Feng must be ready to run now!

Who the fuck can stand such a tough grandpa who is so unruly?

If it's really her, do you admit the engagement? Or refuse?

Admit how?

Promise in front of so many people?

But if she had half the virtuous three of Jingshu, Zhang Feng would be willing, but who dares to marry such an ancestor back?

Think about it.

Zhang Feng has a bigger headache.

The one who didn't pay attention almost confiscated the strength in his hand, which almost broke the glass basin with the glass rod.

"Ding!"

A crisp sound.

Everyone almost recovered.

Then at this time, Zhang Feng found that the initial fog in the basin had made the water extremely viscous, and even began to see a trace of ice residue looming in it.

See.

Zhang Feng raised his arms and shouted, "ladies and gentlemen, it's time to witness miracles!"

"You guys, don't blink at this time!"

Under Zhang Feng's mysterious hint, everyone's eyes haven't blinked for a long time.

Because the people at this time had already been shocked by the things in the transparent glass basin.

When did they see such a magical thing?

At this time, although the weather is indeed a little cold, after all, it is still a little warm at noon. At this time, it is tantamount to Arabian Nights to want the water to naturally condense into ice.

At this time, such a thing suddenly appeared next to their eyes. Who was not shocked?

what is it?

This is the real fucking miracle!

no

It's magic!

At this time, what Zhang Feng said is actually not important

It is important that.

Everyone saw that the water had frozen!

That's the truth.

At this point.

Everyone looked at the basin that was rapidly condensing into ice and the big bowl in the basin. At this time, they were also on the frozen water surface, and couldn't help but absorb the cool air.

The least worried and leisurely thing is Li Chengqian and others. At this time, looking at the appearance of everyone, it is a comfort in their hearts!

Let you bang, let you pretend

Are you stupid now?

Have a look, have a good fucking look, is this thing really ice!

Although they shouted in their hearts, they only dared to show a proud smile.

At this point.

Zhang Feng stopped slowly.

Because.

The ice has completely frozen.

Including the water in the big bowl, although it is only frozen with a thin layer of ice, it is already frozen. It is only a matter of time to completely freeze it.

As for the big basin, it had already become an ice pimple, and the glass basin seemed unable to withstand the low temperature at this time.

There was a small cracking sound in an instant.

"Click!"
