His understanding goes against the heavens, and he realizes immortality in the womb, which shocks Yi

Hearing that the people can't eat now, Yingchen is helpless

He couldn't help but start his thoughts divergence.

[As the saying goes, relying on the mountains to eat the mountains, relying on the sea to eat the sea, the food in the sea can be richer than on land, if it were me, it would be

Build a large number of fishing boats and make large nets to fish. 】

[Anyway, there are so many marine resources in this period that they are flooded, so there is no need to worry about protecting animals or anything. ]

[But in this way, there must be ice, otherwise it will not be transported at all, the fish will stink, and then it is necessary to use saltpeter to make ice.] 】

The saltpeter referred to by Windust refers to potassium nitrate.

When potassium nitrate is dissolved in water, an endothermic reaction will occur, which can gradually reduce the temperature of the water until it drops below the freezing point, at which time the water will solidify into ice.

This is an ancient method that was greatly applied during the Song Dynasty.

People at that time used this principle to make ice cubes to escape the heat or to preserve ice drinks.

Ying Zheng, who heard the voice of Ying Chen's heart throughout the process, was overjoyed.

Does this stinky boy really have a way?!

Fishing boats and nets are good to say, just find the public family, they will definitely be able to build it.

He could understand the need for ice.

When fighting in the north, ice is also used to keep meat fresh, and ice is indeed crucial when it comes to transporting marine fish to the interior.

But what does this saltpeter ice mean?

Can ice be made out of this saltpeter?

If it could be done, wouldn't it be possible to make ice cubes no matter what the season?

It seems that whether this matter can successfully solve the problem of food shortage is at this step!

Ying Zheng's heart was excited, and he couldn't wait to hear about the specific method of saltpeter ice making immediately.

But what made him depressed was that next, Yingchen no longer mentioned saltpeter ice making.

He can't ask directly, otherwise he will expose himself!

Ying Zheng pondered for a moment, and couldn't help but guess in his heart.

Is it easy to make saltpeter ice?

It's so easy that in the eyes of this stinky boy, there is no need to say more?

You can do it just by putting together things?

Thinking of this, Ying Zheng couldn't help but want to give it a try.

He stood up and said to Li Si: "Li Si, you come with me." "

Lees is now completely confused about the situation.

Your Majesty, what does this mean?

Inexplicably, he called him to the Shufei Palace and asked him to repeat the questions he had recounted, not only did not give the answer to help the victims

Instead, he inexplicably took him to what he was going to do?

Li Si prides himself on knowing His Majesty's mind very well, and even if he doesn't understand it, he can at least guess it.

But lately, he didn't understand what His Majesty was thinking at all.

Seeing that His Majesty had already stood up and walked forward, Li Si did not dare to ask more, so he could only honestly follow.

Soon after.

Huan Zheng and Li Si stood by a pool in the palace, waiting silently.

After a while, Zhang Wei came.

He was followed by several shadow guards, carrying a box, which looked very difficult.

Zhang Wei instructed the shadow guards to put down the boxes in turn.

At this time, Lees was already full of question marks.

Didn't His Majesty want to discuss with him about the shortage of food?

Why wait here, watch Zhang Han move boxes?

Could it be that the box contained His Majesty's small treasury?

Does His Majesty want to use his own private money to supplement the treasury and transfer grain from other places?

After the boxes were all placed, Zhang Wei ordered the shadow guards to open the boxes one by one.

Inside the box was nothing else, it was the collected saltpeter.

After Li Si saw that the contents of the box were not gold and silver treasures, he couldn't help but be disappointed.

This box is all saltpeter, what can it do?

At this time, he did not understand even more.

Your Majesty, what is this for?

Isn't there not enough food? What do you do by collecting saltpeter?

Huan Zheng seemed to have seen the puzzlement in Li Si's eyes, and he ordered Zhang Handan: "Zhang Handan, bring a basin of water." "

Zhang Wei got up in response to the sound, went to fetch a basin of water, and put it in front of Huan Zheng.

The clear water waves gently rippled in the sun, reflecting the shadows of several people.

Huan Zheng looked at the saltpeter in the box and said, "Zhang Handan, take a few saltpeters and put them in the water." "

Although Zhang Wei did not understand, he did it one by one.

The white saltpeter was crushed by Zhang Wei and turned into powder.

When the powder is placed in a basin of water, it binds to the water and begins to dissolve rapidly.

Then, the water in the basin soon changed visibly.

The originally clear water waves began to produce tiny ice crystals due to the dissolution of saltpeter.

As more and more saltpeter dissolved, the ice crystals began to spread gradually.

In the end, it spread throughout the basin.

It turned into a piece of ice!

The original water actually turned into ice!

Who can believe it if they didn't see it with their own eyes?!

Li Si and Zhang Handan, who were watching from the sidelines, saw this scene, and their eyes straightened.

The two couldn't believe it.

Now it's obviously not winter, the temperature is so high, how can ice be produced?

Zhang Wei lowered his hand and touched the ice in the basin.

Within reach, it's a piece of coldness.

He was convinced that the ice in the basin was indeed now, not his illusion.

When Li Si saw Zhang Handan's movements, he already understood that it was not his hallucination.

The water does turn to ice!

What the hell is going on here?

What exactly did His Majesty do, and why did this happen?
