The so-called equipment is the body of the lion. Fortunately, since the lion came to Makura, he has changed to the latest model of supercomputer and settled down, and the system has been perfected by him a lot, so he has also made a second-level intelligent system to control the security system of the military factory, and he does not need to stay in the central computer all the time.

Diamond ore is extremely difficult to find, but it is also traceable because, like iron ore, it has companions, which means that if you find this substance, you are very likely to find diamond ore.

There are two types of diamond mines, one is primary mining, which is mined in the place where the diamond originated, and the other is placer mining, which is like gold panning, mining diamonds washed out by rain in places such as beaches.

The primary ore is more difficult to mine, first with open-pit mining, forming many 12-meter-thick steps around the rock tube. When it is too deep to operate, dig a shaft and then drill a horizontal shaft to the vein, such a mine will generally have a deep depth. Moreover, the primary ore must be crushed and sorted before the diamond can be separated, and the diamond particles must be intact when crushed, and it is not a simple matter to find the diamond in the primary mine.

In contrast, the placer mine is relatively simple, so Xu Ziling and they are going to the placer mine this time, the primary mine, he doesn't have this idea at all, of course, if he finds it, as long as the storage capacity is large, he definitely doesn't mind setting up an ore company, but these are all later words.

The three of them acted separately, Xu Ziling prepared the equipment, while Yang Kaiming and Li Cheng prepared the relevant tools and helicopters, intending to dig as soon as they were found.

There are too few diamonds, even if there is a lion, Xu Ziling's confidence is not very strong, although there is a diamond mine in Netan, but it is not easy to find it in a short time.

What's more, diamonds that are too small mean nothing to them at all, but it has been nearly 200 years since the discovery of such a thing, and how many special diamonds have been produced in this period?

After a busy morning, the three of them were finally ready, with sapper shovels, pickaxes, and improvised sieves made of barbed wire.

Nitan is not safe, so in addition to preparing relevant tools, they did not forget to prepare guns and other items, and considering the transport plane they were on, Yang Kaiming not only brought a five-person team, but also arranged a "Thunder Dragon" escort.

Everything was ready, after lunch, the three of them said hello to the family, and then set off.

The transport plane carried several people to the sky, Xu Ziling looked at the "Thunder Dragon" armed plane next to him, and remembered that in this land, their armed aircraft could fly freely without informing the Netan military, and he couldn't help but feel a little proud.

The place chosen today is the river they went to when they first came to Netan, because it is one of the few diamond mines in Netan, but that river is hundreds of kilometers long, and the place where diamonds are found is only a few tens of kilometers of watershed, so Xu Ziling wants to see if there are any diamonds in other parts of the river.

In the past, the straight-line distance was not far, only a distance of more than two hundred kilometers, and under the full speed of the Zhi-9, they arrived at their destination in less than an hour.

The known mine site was in the middle of the river, and after reaching the end, Xu Ziling had the pilot fly at an altitude of about 500 meters and fly slowly upstream.

And he, Yang Kaiming, and Li Cheng, sat in a row and stared at the "oversized tactical watch" that had just been opened in their hands.

said it was super large, but it was actually a tablet that Xu Ziling made out when he was bored, with a ten-inch screen and the functions that a tactical watch should have, "Can this thing be found?" ”

Judging from the appearance, Li Cheng also had one in his hand, so he couldn't help but have some doubts about whether this thing could identify diamonds.

"No problem. You think I've been sitting there in a daze all morning, but I've been doing it for a long time, and I've tested it with diamonds in the lab, and I can definitely find it. "There are too many lies, Xu Ziling doesn't know what Lu Dao's blushing is, where is he busy in the morning? It's just sitting in the office and reading some information, as for the test, he did it, anyway, there are a lot of industrial diamonds in the laboratory, and he doesn't need to look for another one.

On the screen, what is displayed is the same picture as a traditional radar scan, and after the system is initialized for a while, many small red dots appear on the green light curtain, and when he saw this, Xu Ziling immediately said: "Look, this red dot is a diamond." Do you see the shape of the red dot? It is curvilinear in shape, which means that it is distributed in the river, and the scanning distance is 20 kilometers, which means that the red dots are the diamonds stored in the river within 20 kilometers. ”

The distribution of serpentine red dots is dense, and at first glance, it is estimated that there are at least 100,000 of them, and they understand that a red dot represents a diamond, Yang Kaiming and Li Cheng opened their mouths wide, and their faces were sluggish.

"So much? Make no mistake" in their impression, aren't diamonds rare and precious, how can there be so many?

Hearing them say this, Xu Ziling knew that they didn't understand anything at all.

smiled and explained to the two of them: "Don't look at these twenty kilometers there are so many, but there may only be one-tenth, one-twentieth, or even less of the gem quality in it, but it is not as long as it is a diamond that can be set on the ring, most of them can only become industrial diamonds because they contain too many impurities, haven't you seen the industrial diamonds in our laboratory?" ”

"Also, some of the diamonds are too small, so don't look at the numbers, but the actual production is not much."

"Oh, I see, I thought that as long as the diamond was dug out, it could be cut and set, but it turned out that there were gem-grade and industrial-grade." Li Cheng looked suddenly enlightened.

"yes, it seems that we are still ignorant......"

Understanding this question, Li Cheng quickly shifted his mind, "There are so many diamonds on it, can we dig them?" And how can we tell how big it is, or if it can reach gem quality? ”

"Yes, it's useless to tell the light that there are diamonds, we can't dig them out one by one." Yang Kaiming also nodded, expressing the same question.

"There is a master here, so don't fight the idea of this place first, let's go to another place first." Xu Ziling pressed it on the tablet, and a line of menus appeared, "As for how to know if Lu Dao is suitable for us, this is very simple." I'm just showing you a demo, and I haven't been systematically screened yet. ”

After speaking, he clicked on an option in the menu that said "One", and continued: "See, there is a first-level filter, a second-level filter, and the first level is to list gem-grade and industrial-grade; The second level is the screening weight. I set it to more than 15 carats in the system, as long as we select these two options, the top of the screen will be more than 15 carats of gem-quality diamonds. ”

"Then you try it......" Seeing that this thing was so easy to use, Li Cheng immediately became interested.

"Okay."

Even if Li Cheng didn't say it, Xu Ziling would also test it, so he immediately clicked twice on the screen.

And as he clicked his finger, the red dots on the screen swept away, and there was not a single one left.

Seeing this situation, Li Cheng stayed again, "Dozens of kilometers, there is not a single diamond more than fifteen carats, this is too fake, right?" ”

"What's fake, I learned about the situation of this mine before I came, people have been developing it for more than ten years, and there are not ten diamonds mined up to fifteen carats, fifteen carats do you think it's so easy to find."

"Alas...... Then we estimate that this time it is suspended. ”

"I'm not worried about this, there is such an artifact, I'm not afraid that I won't find the diamond, Nitan can't find it, it's a big deal to go to South Africa or Australia, Zaire to find it, it's just a big deal to spend a little more time." Yang Kaiming's attitude is completely different from Li Cheng's, he is very optimistic, "But I heard that there are blue and red colored diamonds in diamonds, even if there are ten carats, it is rare, your system has such a setting, if there are colored diamonds but not fifteen carats, isn't it missed?" ”？？？？

Xu Ziling slapped his head violently, Yang Kaiming was right, he remembered the transparent diamond, and he forgot that there was such a thing as colored diamonds, after such a reminder, he remembered a report he had read before, which specific country in Africa he forgot, there is a red diamond of less than 0.95 carats that was sold for more than 900,000 US dollars, Africa has blue diamonds, red diamonds, and yellow diamonds, of which yellow diamonds are relatively cheaper, but blue diamonds and red diamonds are extremely valuable and absolutely rare. A few carats is rare for decades, and if you really miss it, wouldn't it be damned?

"Brother Kai Ming's right, I really forgot about this, no, I have to change it immediately......" After saying that, he immediately communicated with the lion in his mind, and at the same time his fingers flew and pressed on the tablet.

After five minutes, the movement of his hand stopped, "Okay, it's done, thanks to your reminder, Brother Kaiming, otherwise, even if there are colored diamonds, we really missed it." ”

"Accident...... Hehe...... It was a surprise......"

Yang Kaiming didn't expect that he casually asked a question to fill a loophole that Xu Ziling didn't consider, and he was immediately happy.

The helicopter flew at a speed of one hundred and fifty kilometers per hour, and soon flew over the mine that had been discovered below, and flew up the river in the air, flying for more than half an hour, and everyone found nothing.

"It doesn't seem to be out of stock." muttered, but let the pilot continue to fly.

It is a pity that they did not find the shadow of the diamond until they flew to the source of the river, and at this time, it was more than 400 kilometers away from the camp, and it was about to reach the combat radius of the helicopter, so he had no choice but to let the pilot start to return. I'm going to go downstream tomorrow, and if I can't find it, I'm going to South Africa or other African countries.
