The next day, Qin Ru started mining directly from a depth of five hundred meters.

With yesterday's accumulation.

At the end of the day, thirty tons of raw ore were mined.

But what made Qin Ru helpless.

In today's mining, the purity is still not up, and the proportion of agate is pitifully low.

Suffice it to say that thirty tons of ore. 29.6 tons, all ordinary rocks.

Another big loss!

In the middle of the night, Qin Ru stood on the deck.

Looking out at the sea.

Silence.

There's absolutely nothing wrong with the location.

This is indeed an agate vein.

But how can all the mined agate ore be of low purity?

Qin Ru was silent.

"Is it because the world is different?" Qin Ru hesitated.

The news of this agate mine was obtained from Zhu Chenfan's memory.

Qin Ru closed his eyes and recalled Zhu Chenfan's record of this vein.

After a while, Qin Ru found the problem.

For this vein, Zhu Chenfan saw it from the news.

Because the news broadcast that this vein found a pure agate ore with a diameter of five meters.

Then it made international headlines.

After that, it was connected several times, and even found more than ten meters of pure raw ore.

Zhu Chenfan was curious at that time, so he checked it on the Internet.

So what?

So, without Zhu Chenfan knowing before, how long did the Azure Mineral Company mine? Don't know at all?

It is no wonder that the agate raw ore mined by himself is not only pitifully low, but also very low in purity.

It's all to the extent that it's sold in wheels.

"Deeper?" Qin Ru was silent.

If your guess is correct.

Then, none of the agate ores on the surface are of high purity, and it may be at a deeper seabed that there will be high-purity agate ores.

Next.

Qin Ru walked into the command center.

"Stop, I'm announcing new mining work!"

"Today, the blue fish group doesn't have to go down, the ocean group, the blue group, today's goal is a depth of 800 meters, there is no need for the pipeline group to work, the length of the pipeline brought is only 600 meters, notify the equipment group over there, and install a storage box for the blue 2 and blue 3!"

"Boss, we're going to mine eight hundred meters?"

Zhang Daoyu was stunned.

Qin Ru nodded, "The purity of the current mining is pitifully low, if you continue to mine like this, you can only go back crying, it is better to go to a deeper place!" ”

"Boss, but the anti-stress ...... of marine robots"

Qin Ru waved his hand, "Let's work!" ”

The others saw that Qin Ru insisted like this.

It's hard to say anything.

Can only start to work.

Blue Two and Blue Three began to add a storage box.

The transportation work was carried out by the two of them.

With the experience of the previous two times.

Today's marine robots don't need steel cables to sustain them.

Straight to the bottom.

Towards today's goal, a depth of 800 meters.

Above 500 meters, it already belongs to the deep sea area.

Not to mention eight hundred meters.

Bright searchlights, where the luminosity is very low.

Fortunately, both the Blue 2 and the Blue 3 are equipped with more than ten strong light searchlights.

Barely able to see clearly.

"Boss, the signal is a little unstable!" When the dive reached 700 meters.

The signal began to become erratic.

Qin Ru frowned, "Put the signal booster, the target, three hundred meters!" ”

"Yes!"

Four devices were dropped from the ship.

Straight down to a depth of 300 meters.

Then expand.

as a signal relay exists.

Strengthen the signal transmission of Azure unmanned submarines and marine robots.

The bottom of the sea is not just a matter of lack of light.

More important is the issue of signal transmission.

This is why many submarines are difficult to detect when they are sailing at depths of 600 to 900 meters.

Because, the signal emitted by the submarine itself will be interfered with by the situation on the bottom of the sea.

And the signal detected from the top down, will also be canceled out.

This is especially true when you are diving at a depth of more than 1,000 meters, like a typhoon.

Even if the noise itself is loud, it will be distorted by the signal on the bottom of the sea, so that the US nuclear submarine at six or seven hundred meters will not be able to detect the typhoon class below.

This happened during the Cold War.

In the Atlantic, an American nuclear submarine and a British nuclear submarine collided, and underneath the two of them, there was also a Soviet nuclear submarine.

As a result, all three nuclear submarines were damaged, especially the American one, which was directly silent, and all the people on the submarine died.

Below the depths of the ocean, signal transmission is weakened.

If you don't activate the main sonar to dodge.

It's hard to know that there will be a submarine above and below in front of you.

To this end, Qin Ru created a signal booster.

Theoretically, a signal booster can increase the signal transmission by 500 meters.

However, as the water deepens, the transmission of the signal also becomes weaker.

If it is a signal transmission of 1,000 meters below 800 meters, it is very reluctant.

By the time a thousand meters are provided with a signal for 1,100 meters, it is almost a disruption.

With four signal boosters.

The signals of the marine robot and the Azure unmanned submarine have also stabilized.

Once the signal is stable, the picture is much clearer.

"There, there's a platform, in the past! Qin Ru pointed to an area on the screen.

The Blue Two, having received the order, began to drive over.

It is a platform of about thirty meters or so.

Below, there is the dark deep sea.

Here, it was already ten nautical miles north of the mining area two days ago.

Fourteen nautical miles away, there is a trench at least three thousand meters deep.

And here, although there is no data, but according to the comparison of the data obtained by the major oceanic bureaus around the world, a data from the French Oceanographic Agency has a detection record here, and the water depth is about 1,600 meters to 1,900 meters.

So, the rate of decline is very slow.

The four marine robots all rely on diving on the blue unmanned submarine to avoid diving too fast.

Landing on the platform, the four ocean robots began to detach.

Start analyzing the data against the mountain wall.

"Boss, the analysis shows that there is no agate mine here!"

Qin Ru did not speak, but was silent.

Because, it's a bit familiar here.

Qin Ru frowned, thinking of this carefully.

Suddenly, Qin Ru thought of it.

When Zhu Chenfan checked on the Internet, he had seen this, but when he looked at it, this platform had been widened by hundreds of meters, and there was a very huge hole.

And the first agate, which is one meter in diameter, was mined from here! Moreover, at a depth of about thirty to fifty meters, there will be agate ore with high purity!

Thinking of this, Qin Ru was overjoyed.

"Here, dig for me, the depth, fifty meters!"

"Huh?"

Everyone was stunned.

"Oh ghost! Dig for me! ”

Qin Ru was angry, and everyone didn't dare to say anything.

The marine group begins to control the marine robots and begins to dig in.

High-vibration cutting edge under high-speed digging.

The progress is very obvious.

I dug for a morning, and I had already dug thirty meters wide.

Originally, many people were a little helpless.

However, agate mines began to be discovered.

After lunch, and after checking that there is nothing wrong with the marine robot, go down to the platform again.

Keep digging.

At about four o'clock in the afternoon, the digging reached a depth of fifty meters.

"From here, start, in four directions, dig left and right for me, and if you find agate ore, cut off those useless ordinary rocks for me, reduce the volume, and pull it back for me by the unmanned submarine!"

Four marine robots began to dig in all directions.

Large quantities of agate ore began to be discovered.

The biggest feature of this agate submarine vein is that the deeper it is, the higher the purity.

Unlike other veins that are length, this one is a high vein.

The length of the surface vein is at most 16 nautical miles.

And the depth of the vein, according to Zhu Chenfan's memory, the blue mineral has been dug to 1,400 meters, and it is still found.

However, the agate ore itself is excessively scarce, resulting in too few reserves of this vein.

However, Qin Ru always felt that there was something else in this vein.

Otherwise, it would be impossible to attract the blue mineral to dig heavily on this small agate vein.

Although their own world and the world of Zhuchen Fan are different to a certain extent, these are enough to remember the existence of history, and they will definitely exist.

Therefore, Qin Ru wanted to see what else was worthy of Canglan Technology's interest in the agate veins that had been dug up for so many years by Canglan Technology for so many years.

With this vein of resources, a large amount of ore of purity was excavated in the following days.

On the third day of digging, the value of the excavated agate ore had exceeded 10 billion US dollars.

The important thing is after the discovery of the 0.7-meter-diameter agate pure ore.

It exploded in an instant.

Li Shiying sent a special video over.

"I said, boss, I want one!" Li Shiying spoke directly.

The eyes in the video seem to have penetrated thousands of kilometers to come here.

"Whatever you want, did you start recording over there?"

If you confirm that this is the vein.

These are just hors d'oeuvres.

Li Shiying wanted it, so she picked it up.

Qin Ru didn't care much.

Billions, just send it, and there will be no one!

"I've already asked the secretary to keep a record, and I'll contact the jeweler!"

Qin Ru shook his head, "No, it's not to contact the jeweler, I heard that Sotheby's annual auction is still a week away?" ”

Li Shiying was stunned, "Boss, what do you mean?" ”

Qin Ru turned the video to the side.

A 0.6-meter-diameter black agate stone is presented with "You say, if you send this to Sotheby's annual auction, how much will it sell for?" ”

Li Shiying was silent.

0.7 meters is the largest found so far, but that one is not very pure.

But this 0.6-meter black agate is very pure, if it is put up for auction, then the whole world will be shaken, right?

"Boss, you really know how to play, I'll contact Sotheby's right away, I'm sure there's no reason why they will refuse, besides, other auction houses are also conducting annual auctions!"

"Then as soon as possible! I'll go back tomorrow, and I'll give you the coordinates when the time comes, and let Sotheby's plane ship it directly! Time is running out! ”
