I Lost It! It Turns out That the Anchor is Cultivating Immortals

When the sea surface sinks, the seawater left in the islands evaporates, forming sea salt crystals.

After geological changes, buried under the soil and rocks, the ore of rock salt will be formed.

However, Su Mubai is not too sure, after all, there are not too few ore minerals that are exhausted with rock salt.

step by step,

Su Mubai walked over to the stone wall,

The color is a little yellowish, the crystals are not as transparent as rock salt, and some of these stones are embedded in the stone wall, only a small part is exposed outside.

"I don't know if it's alum or natural soda..."

The only thing Su Mubai can be sure of is that this is not rock salt.

At least it doesn't smell like rock salt.

"Huh? This is... ice?"

However, just when Su Mubai was about to get a piece and look at it, a drop of water dripped from a crevice above the stone wall.

Su Mubai's pupils shrank suddenly.

It turned out that on this white crystal, there was a piece covered with a thin layer of ice,

And after the perception domain spread, Su Mubai found that the water droplets that had just dropped were slowly condensing, turning from liquid to semi-permeable ice crystals.

Seeing this, he understood,

This is neither alum nor natural soda stone, but saltpeter.

What is saltpeter?

Its other name is called natural ice maker.

The ancients did not have electricity, so naturally they did not have anything like refrigerators, and the ice they used was naturally not collected and sent from the Antarctic and North Pole.

Not to mention whether there were planes at that time, even if there were, from collection to transportation, after arriving at the destination, it is estimated that there will not be much left.

And the cost is very expensive,

So making ice with saltpeter was the mainstream at that time.

Because the characteristic of saltpeter is that when dissolved in water, it will absorb a lot of heat,

As long as there is enough saltpeter, even in summer, you can make ice cubes without a refrigerator!

More importantly, ice made of saltpeter can be eaten directly without any adverse reactions or poisoning.

"It seems that even if we hunt wild boars in the future, we don't need to eat bacon every day..." Su Mubai smiled.

He reached out and took a piece of ice from the saltpeter. It was thin, and it quickly melted into water in his hand.

It's icy cold, completely different from the temperature on this island,

"Huh?"

Hai Dongqing flapped its wings and flew over from the wolf,

Seeing that the ice cube in Su Mubai's hand melted into water, a little curiosity appeared in her round eyes.

Su Mubai smiled and said, "This is ice. When the temperature of the water drops, it will condense into such translucent ice cubes."

ice cubes?

Another thing it has never heard of, just like the vine pepper.

"This is different from rattan pepper, you can eat it directly." Su Mubai felt Hai Dongqing's curiosity and handed the ice cube to it.

The curious Hai Dongqing tilted his head, opened his bird's beak and pecked, and suddenly an icy cold smell swept his body,

The heat brought by the sun seemed to be swept away in an instant.

Comfortable!

Hai Dongqing smashed it, smashed its mouth, a little unfinished,

However, in Su Mubai's hand, the thing called ice cubes was gone.

Turning his eyes, Hai Dongqing focused his gaze on the place where Su Mubai took off the ice.

snatched,

The hard bird's beak pecked off an ice cube, grunted, and swallowed it into its stomach.

"Wow, Lord 55zw just ate it, it seems to be ice, right? I didn't expect there to be ice on this island?"

"Upstairs, if you don't speak, no one will know that you are ignorant. Have you seen those white stones? If you read correctly, those things are natural ice-making agents."

"Natural ice-making agent? Saltpeter? Damn! I thought it was rock salt, but I didn't expect it to be saltpeter. Su Shen is also lucky, right?"

"Mom, I really deserve to be a man favored by the goddess of luck. The luck is really good. First, the pepper tree, and then the pepper. In the end, before taking a few steps, I found saltpeter again..."

"This thing is a good thing. In ancient times, the ice used by the emperor was also made from this thing. As long as it melts in water, it can absorb a lot of heat and condense into ice, which is very convenient!"

"Yes, it is said that it can be repeated. After melting, it can be re-extracted by distillation to obtain saltpeter."

"Didn't God Su found a treasure? It's a hot day, and everyone else is so hot. We God Su lay on a chair and drank cold drinks. Thinking about it is exciting!"
