While it's uncertain whether it's a usable ore or just a less useful ore, the discovery of a stone of size and color is always of considerable interest.

Of course, I still hope that it is better to use ore than some home decoration materials like marble, which will not be of much use to me!

The impression is clearer when approached, and its structure and color can take a lot of the guesswork out of it, especially the many stones.

My curiosity made me very curious to find out what the stone was, so I not only got close to the mountain wall to smell the stone, but even took a piece and licked it with my tongue.

The smell is indescribably faint, and it is normal for any natural stone to have a strong smell, with very few exceptions, but it is not among the exceptions.

However, its taste is quite pungent, and there is a cool feeling under the bitterness, like a popsicle, the effect is naturally very poor, but it is also impressive!

Its effect is imaginative and combined with its smell and taste, I already have a bold guess......

The next step is to take a piece and verify it to draw conclusions, even if you are already six or seven percent sure at this point.

I picked up two fist-sized stones at the mountain wall and then went down the hill to return to the well, verifying that I still needed the help of water.

I dug a small pit two meters away from the side of the well that could hold a small basin of water, filled it with water, threw two stones into it and drowned in the water, and then just waited, time will help me with the next steps!

After a while, only about three to five minutes later, it was clear that the water in the pit was chemically reacting with the stones, and the stones were absorbing a lot of heat from the water.

The temperature of the water has dropped by at least two degrees compared to the beginning, which is not much, but if you increase the stone tenfold or hundredfold, the effect will be very different, and the effect of prolonging the time may be more obvious.

......

Therefore, it is not difficult to guess that there are not many stones that can achieve rapid cooling, coupled with its color and shape, it is completely certain that saltpeter has been found!

What's more critical is that there is more than a star and a half, this is a saltpeter mine with a lot of reserves, it is difficult to describe the number of specific quantities, but the preliminary estimate is that I will not be able to mine it in a lifetime.

This saltpeter mine is located in the middle of the mountain wall, and the exposed area reaches tens of square meters, and as the mining depth increases, it is believed that the reserves inside will be even larger.

This result always feels a little illusory, and I can't help but pinch myself, and only after realizing that the pain is obvious is that I am sure that this is not a dream, everything is real!

Saltpeter has many uses, but most of them I may not use, for example, it is an important ingredient in gunpowder, and it can also be used to make glass and fertilizer.

Several uses are extremely huge, but unfortunately these chemicals are all areas that I don't understand, so I can only stare dryly!

The remaining ones are slightly less effective than the previous ones, but for me they are even more important, and even have a huge impact.

One of the major effects is that saltpeter can be used as a medicine to treat a variety of diseases, and its medicinal value itself is quite average, but for me it can be magnified many times.

Lack of medicines is the norm for me, medicines for any ailment, and finding any new medicine is always a joy to use, maybe one day.

Although it doesn't mean as much to me as herbs like thistle and dandelion, it fills a gap, and what is even more important is its value!

The second major effect is that saltpeter can be used to make ice, and when the amount reaches a certain level, it will absorb most of the heat in the water and finally condense into ice.

Of course, this also needs to balance the amount of saltpeter and water, as well as the size of saltpeter, maybe you can use a whole stone, or you may have to roll it into powder, but it is always effective, just experiment slowly!

If it works, it's a big deal, and there's a replacement for the refrigerator you've been thinking about......

Refrigeration has had a profound impact on me, probably second only to electricity, especially now that we have cellars.

......

It is conceivable that if the exploration of the island had started and ended, the area on the top of the mountain would have been explored, and the result would have been the discovery of saltpeter.

This situation will advance the discovery time of saltpeter by nearly three years, not only to enjoy it three years earlier, but also the hundreds of catties of crocodile meat left over from the original removal of crocodiles can be preserved, and they can be frozen in ice directly.

Regret is very regretful, it's a pity, but unfortunately there is no regret medicine in this world, and you have to suffer the corresponding consequences for your original laziness and snake tail!

People are very selfish, and the first thing that comes to mind when they think of the huge effect of saltpeter is an indescribable sense of surprise, but then they just want to move a large amount of saltpeter back home and turn the cellar into an ice cellar!

What a wonderful thing it would be if I had an ice cellar, I used to just think about how nice it would be to have a refrigerator, and an ice cellar is equal to countless refrigerators, and its volume is fifty or a hundred times larger......

Even if the reality is often not as rosy as it should be, it is good to settle for a lower temperature of 5 or 10 degrees Celsius, and it will make all kinds of items and meat easier to preserve!

So after rehearsing the process and the results in my mind, I realized that it meant a lot to me.

The next step is to start the actual operation, turn it all into reality as soon as possible, and feel that every extra day of waiting is your own loss!

Unlike in the past, the first step was to go home first, because I didn't realize that there would be such a big discovery before I came.

I didn't have much illusions about the last small area, and it could be explored in three to five hours, so I didn't bring any tools except for a few weapons, not even a backpack.

This is a trivial matter, and it is not worth mentioning a trip home compared to the discovery of saltpeter, after all, in addition to carrying a basket, you also have to go home and bring other tools.

......

These tools are mainly iron tools used to cut rocks, such as chisels and axes, which are not dirt, and even when they are dry, the soil cannot be clasped by hand.

Although it is not as difficult to collect saltpeter ore as it was when the well was sinked, it is not something that can be picked up everywhere, and it still has to be chiseled down from the mountain wall piece by piece.

However, it is easier than I thought when it was dug up, and the main reason for this phenomenon is that the exposed area is large enough, and the west side is not bright and the east side is bright, so when it is difficult to chisel in one place, you can immediately change the position and continue to do it.

What's more, the weight of the stone is well known, and it is almost the limit to go down the mountain with fifty pounds on your back, and the weight of fifty pounds may only be the size of two or three basketballs, and it can be chiseled out in less than a quarter of an hour!

Drilling stones is not the most strenuous, but the process of transporting them is more of a headache.

This distance is quite not close, from the location of the well to the house is about 600 meters, the well to the mountain is more than 100 meters, it is not difficult to walk 800 meters with a load, the difficulty is to walk five, ten, or even twenty times to ensure that there is enough saltpeter in the cellar!

Even if there is a fairly flat road between the well and the house, which can reduce some difficulty, you still have to walk back step by step.

In particular, the process of carrying dozens of pounds down the mountain from the top of the mountain is particularly difficult, the road up and down the mountain is not narrow, and it is quite easy to walk without carrying things, but it is very dangerous to go down the mountain with a load, after all, it is not like a ladder, you can step evenly and steadily.

You have to be careful at every step of the way down, and if you're not careful, you might roll down the hill like a rock, and if you're lucky, you might be blocked by a tree, and if you're unlucky, you'll have to be ......

After two trips down the mountain with saltpeter on my back, I stopped doing this, it was too dangerous!

It's acceptable to be far away, but it's not so worth risking your life every time for dozens of catties of saltpeter.

The process of going down the mountain is quite thrilling, there are three times I almost slipped under my feet and rolled down the mountain with saltpeter, the result will naturally not be very good, and the blood flow of the head is the lightest consequence!

......

In view of this, the only way to stop the transportation of saltpeter is to take half a day to a day to repair the road, at least to ensure that there is no fear when going down the mountain.

After all, there may be a lot of opportunities to go up the mountain after saltpeter is found in the mountain, and the amount of ice needed to make ice is not a few, especially to meet the needs of a cellar.

The process of building the road is quite simple, and after more than half a day, the transportation of saltpeter can continue, after all, there is a ready-made road from the foot of the mountain to the location of the well.

On the third day, the operation continued, five trips back and forth in one day, and almost 300 catties were transported to the home.

Three hundred catties may seem like a lot in terms of quantity, but it is a stone, even three hundred catties of dirt is only a small pile, let alone three hundred catties of stones, I feel that I am curled up on the ground and more conspicuous than this pile of stones.

This kind of efficiency is really unsatisfying, and the key is to spend seven or eight hours back and forth five times a day and tire people half to death, and the pay and return seem to be too unequal!

At present, the difficulties are mainly concentrated in going down the mountain and going up the mountain, which will take about half an hour, if you can transport the saltpeter directly at the foot of the mountain to your home, there is no problem in transporting five or six hundred catties a day on a flat road of five hundred meters!

A living person can't let his urine suffocate to death, and if I can't do it, I'll give birth to another plan, and the effect of the new method will be satisfying......

On the fourth day I stopped transporting saltpeter and dug a trough from the top of the mountain to the bottom of the mountain, a relatively straight trough with a width and depth of more than 40 centimeters, which extended directly to the side of the road at the foot of the mountain.

Believe me, someone has already figured it out, yes, it is to smash saltpeter to the size of a fist and flow down the sink like water to the bottom of the mountain.

With a drop of more than 100 meters, you can easily reach the foot of the mountain, even if you are sometimes blocked, you can continue to roll down with a gentle scrape, which is ten times less effort than carrying it!

The tank lasted two days and then went into use, and when the massive amount of saltpeter rolled down it without hindrance, I knew that my new method had succeeded, and I no longer had to go up and down the hill repeatedly.
