If Feng Jun had paid enough attention, it was possible to find sonar detection, but he didn't think about it at all.

This is in the vast Pacific Ocean, and he is working under the sea, how can he think of beware of people?

After digging to a depth of seven thousand meters, the aura had reached a very strong level, but the temperature had also reached five or six hundred degrees, even if he was holding the aura cover, Feng Jun felt a little hot.

He went to the mobile phone plane to take a breath of relief, and after diving three hundred meters, he took out his mobile phone - it really can't hold on, is the spirit stone mine still far away?

Not far away, there are still more than 800 meters, right at your feet.

Feng Jun moved sideways for almost another day, roughly estimating the size of the spirit stone mine.

The area is about ten square kilometers, and the thickness is not very clear at present, but the scale of this area is considered a "scattered small mine" on the mobile phone plane.

Of course, in the case of the earth, scattered small mines are normal, and if they are really large mines, it is impossible to survive until now.

Now that you have found the mine, then don't say anything, let's dig first, Feng Jun is a little happy in his heart, the spirit gathering array here in Australia, finally no longer needs Luohua to produce spirit stones, he still managed not to let a piece of spirit stone flow out of Huaxia.

Feng Jun has a certain understanding of the mining of spirit stones, most of the spirit stone mines in the mobile phone plane are in the hands of big forces, but the relevant knowledge about spirit stone mining has not been blocked by those big forces, and there are many relevant books.

This is not to say that the big forces encourage the small forces to steal the spirit stone mine, but to let everyone know how the spirit stone mine should be mined - if it is not mined well, it will greatly affect the output of the spirit stone, and even destroy the ore vein.

In the final analysis, the spirit stone mine is a resource for all immortal cultivators, and if it is not mined properly, the loss is everyone's.

For the big forces, the smaller the forces, the more they should learn these things - you can't keep them anyway, it doesn't matter if you take advantage of it, but you are definitely not allowed to destroy my spirit stone mine!

The logic is overbearing, but it's also realistic.

However, Feng Jun did not adopt that kind of prudent mining method, it was too time-consuming and energy-you must know that the main people who mined the spirit stone ore on the mobile phone plane were mainly in the metamorphosis stage and martial arts, and there were not many qi refining periods, so it was impossible for him to waste his time like this.

Secondly, he does not think about sustainability, mining here is a hammer deal, take as much as you want - he can't think about leaving it to future generations, as he does at home.

As for saying that the mining is not suitable, it will lead to the escape of the spirit stone mine, he doesn't care even more, anyway, the escaping aura can't escape from this plane, it is nothing more than from the Australian side, escaping to the world.

If this is really the case, Huaxia is the beneficiary, and this spirit stone vein has existed near Australia for so long, and no one has found it, and there is no circulating aura, is that considered aura?

As for whether Huaxia still has the aura in circulation, it is still obscured by the Gathering Breath Array - well, that's another question.

Therefore, Feng Jun adopts the most efficient mining method - destructive mining.

The spirit stone mine is not only a spirit stone, but also a rock with extremely high hardness.

Extremely high hardness is a hard indicator, in fact, the original intention is that the density is very high, and the rock with a little less density cannot block the penetration of aura.

In a spirit stone mine, a cubic rock may only have one spirit stone.

It's like panning for gold, most of it is just sand, and you can make money by digging for a little gold.

It is precisely because of this that the spirit stone mines in the mobile phone plane are mainly mined by the metamorphosis period and martial artists.

Normal mining during the gas refining period does not dare to guarantee how much money can be made, and Feng Jun is a master of the dust.

There are other ways to mine spirit stone mines during the dust period, for example, fossils are mud, and the rocks are turned into mud, and the spirit stones come out naturally.

As an aside, in fact, there are also fossils that can be turned into mud during the Qi refining period, but the density of the rocks with the spirit stones is not generally large, and if you want to turn them into mud, you need a lot of high-quality spiritual energy.

In particular, the fossil is a mud quarrying spirit stone mine, although it is fast, but there is a big drawback - it will destroy the vein structure!

Yes, this is the legendary destructive mining.

However, for the current Feng Jun, the advantage that can be taken overseas is that it is picked up for nothing, and it doesn't matter to him at all - in the 100 years when China was in recession, others did the same, you can do it, I can't do it?

As soon as he made a move, he was quite ruthless, chose an angle, and directly destructively mined.

It was always difficult at first, but he melted more than 300 rocks before he really entered the spirit stone mine, and mined the first spirit stone, a piece the size of a human head, and could almost cut out seven or eight standard spirit stones.

However, when I saw the red spirit stone, all the fatigue disappeared.

However, it was really difficult to mine the spirit stone vein, and after that, he was busy for two whole days, and he also went to the mobile phone plane to replenish the spiritual energy once, but he only mined more than five hundred spirit stones, which was outrageously inefficient.

Strictly speaking, for a dusty intermediate level, he can have a fixed income of more than 200 spirit stones per day, which is actually not too aggrieved, 70,000 spirit stones in a year, 700,000 in ten years, and if he wants to buy some high-end items such as Xingzai, he will not be stretched.

Moreover, five hundred spirit stones will have to be used to make a move-this is a probability of death.

However, the destructive mining of the spirit stone mine, such a rate of return, is still a bit low, indicating that this spirit stone mine is really average.

However, after all, it was a scattered spirit stone mine, who could expect more? Even if it was a large spirit stone mine, it would have to hire low-level cultivators to mine it—it would be too worthwhile to use high-level cultivators.

But Feng Jun was not satisfied, and the mineral deposits he had mined at the moment were far less than one ten-thousandth.

In this way, the entire mining of this small spirit stone mine may be worth tens of millions of spirit stones—but the problem is that it may take him thirty years...... And even more.

Destructive mining is so inefficient that he has to think about it...... Are there any other ways to be more efficient?

So he stopped mining - no matter what, there are more than 500 spirit stones at the moment, and this little cost overseas must have stopped.

Next, he felt the need to ask the Shadow Boss for advice.

As for the spirit stone mine here, it is good to stop like this, Feng Jun feels that there is not much of a problem, the effect of the spell of fossils into mud is temporary, and it will soon return to stone, which can basically cover up the traces of mining.

Even if the traces can't be completely concealed, Feng Jun doesn't care very much, he has dug through more than 7,000 meters of rock, not to mention, there is nearly 2,000 meters of sea water above the rock.

At present, the technology of seabed mining in the earth world cannot do this, and it is estimated that it will be difficult to achieve it in the short term.

It is the spirit stone mine in Lashan League, once it is discovered, it is too easy to be mined.

However, what Feng Jun didn't expect was that a day after he left here, two submarines quietly drove over, and there was also an additional research ship and a destroyer on the sea - there is no doubt that these are all ships of the Mai country, and Australia does not have such capabilities.

It was also a coincidence that the people of Mai were able to come, and the Seventh Fleet had a show not far away, and after the exercise, I heard that there was a sonar and found something unusual here, so I came to take a look.

The hole dug by Feng Jun was not big, nor was it small, and it was disguised when he left, so it would not be possible to find it under normal circumstances.

But the two submarines searched very carefully, and the coral reef is not only convenient for fish to hide, but if you really want to form a hole, the submarine can also hide, so since you are here, you should search carefully.

Then, one of the three holes dug by Feng Jun was detected by sonar.

Feng Jun took Sophia back to Amsdam and continued to wait for the pull of the leyline, and Sophia had disappeared from time to time recently, and others were used to it.

Two days later, he suddenly remembered that he didn't know if there could be a medium-grade spirit stone in the spirit stone mine, so that night, he quietly came to a coral reef more than a thousand kilometers away.

After coming here, he was surprised to find that there was a Maiguo warship, and he was surprised for a while, and he couldn't help but release his divine sense to perceive it.

It turned out that the Meiguo people discovered a vertical channel he dug up, although it was only more than 1,000 meters deep, which was the one he gave up, but they found this channel on the coral reef, and there was a human factor.

When Feng Jun first dug the coral reef, the corals dug up were directly collected into the talisman, and later there was no backfilling, and he used fossils to dig coral tunnels, but the texture of coral reefs is different from ordinary stones.

As a result, the walls of the pit are quite different from corals, as if there is a layer of glass on the surface of a nuclear storm.

However, the tunnel, which is nearly a kilometer underwater, is also difficult to inspect carefully.

Now the warship is guarding here, just waiting to bring in a deep-diving robot and put it into the depths to investigate carefully.

Feng Jun thought for a while, and simply dragged all four ships to the mobile phone plane, including two submarines - of course, none of the relevant personnel on it could survive.

More than two hundred lives have disappeared, but Feng Jun's heart does not fluctuate too much, the interests involved are too huge, dead people are a normal thing, it is only to blame you for discovering things that should not be discovered.

The reason why he hesitated was because he thought that the news had leaked out, and there would definitely be more people coming, so he would consider the question of whether to kill the other party, and then decided - it was a big deal to artificially create a "Bermuda mystery".

And in the ocean, there is no shortage of legends about ghost ships.

These four ships, especially the destroyer, had real-time contact with the satellite, and only then disappeared, and the mainland of the country already knew about it, and the alarm bell sounded for a while.

Immediately, a satellite paid attention to the wrecked area, but found that there was a thunderstorm here, as if there was an electromagnetic storm.

After a while, the thunder and lightning stopped, and the missing ship had not yet been contacted, because it was at night, and the military of the United States only received strong electromagnetic interference, and it would take a while to repair it, but it was not very anxious.

It was not until more than an hour later, when the four missing ships could not be contacted by various means, that the military really paid attention to it and sent a rescue fleet composed of four ships to sail to the area where the accident occurred.

At this time, Feng Jun was in the sea, wantonly destroying coral reefs.
