The 7,000-meter-long track resembles a seaweed in the sea, swaying slowly with the ocean currents.

A 500-meter-long graphene track with titanium rings at both ends. The 14 segmented tracks form the ladder from the deep sea to the shallow sea at a depth of 7,000 meters.

The entire track cost 5 million crystals, which is almost equivalent to the total amount of NAC's food trade in a month.

In the whole set of equipment, the highest cost is the 15 titanium alloy rings. It not only plays the role of fixing the graphene track, but also can control the water depth freely like a submarine. And according to the direction of the ocean current, the titanium alloy ring can also move in the opposite direction through the blade engine at four angles to prevent the huge tidal force from tearing the entire graphene track.

When the robotic arm of the water drop places the 6-meter-long, 2-meter-diameter ellipsoidal "elevator" on the bottom track, the entire subsea mining rig is completely deployed.

Two suction cups underwater grind the marine sedimentary rock, which is then transported to a "cylinder" by means of a graphene hose. The cylinder undergoes preliminary beneficiation and the rock is fragmented twice. Sedimentary rocks with poor hardness are crushed into crumbs and blown directly into the sea through screens. Manganese nodules, on the other hand, can be screened and sent to the "elevator" at the top.

When the elevator is filled with minerals, the segmented graphene rails are energized. The entire ellipsoid, like a cannonball from an electromagnetic cannon, is accelerated by graphene guides to the shallow sea area.

When the minerals are delivered to a shallow depth of about 100 meters, they can be salvaged with modern equipment.

The staff on standby on the offshore platform only need to confirm that the minerals have been sent according to the signals from under the sea, and then send out salvage boats to scoop up the minerals sent to a depth of 100 meters with divers and trawls.

When the minerals from the offshore platform accumulate to a certain amount, they are then pulled by a ship to the manganese nodule refinery on Anga Island for refining. At that time, the new country's iron, manganese, and molybdenum production will no longer need to rely on imports, and its own production will be able to meet the industrial needs of Anka Island.

After all this, Jiang Chen deployed two 3D-printed ocean current generator sets on the seabed to power the entire mining facility.

Counting Shuidi No. 1, the cost of the entire facility has exceeded 7 million subcrystals.

Although there is no doubt that it is somewhat expensive, Jiang Chen believes that the investment will definitely be worth it.

Don't say anything else. Even at the market price of the sixth block, the price of 1 kilogram of molybdenum ore is almost 10 subcrystals, and as long as 700 tons of molybdenum ore are mined, this cost will almost come back.

And the reserves of manganese nodule deposits on the seabed are not only measured in millions of tons?

The whole set of mining equipment has no problems at all in the current sea area for ten years.

After returning to Coconut Fruit Island, Jiang Chen called Yang Yuan and told him about the possibility of starting mining.

"The problem of seabed mining has been solved?" Yang Yuan immediately asked in surprise after hearing Jiang Chen say that he could send workers to work on the offshore platform.

"That's right. I'll send you the exact mining process by email in a moment. A mining boat, a fishing boat, two divers, an observer, that's probably all you need. Jiang Chen said with a smile.

Yang Yuan frowned suspiciously.

"But how do you get the mine out of the deep sea? Don't tell me to ask divers to go to a depth of 7,500 meters and get an awl to chisel. ”

"Am I an idiot?" Jiang Chen scolded with a smile, "Okay, you don't have to worry about this, I've already solved it." I'll send you an email in a moment. You know what the whole mining rig is all about. Don't be scared of the cutting-edge technology of the Future People Group. ”

Yang Yuan glanced at his phone.

Joke. In any case, I am also a graduate student from the University of Western Australia, and a top student who signed a contract with Rio Tinto in the first year of graduate school. What mining equipment has not been seen?

It was the first time he had heard of something that could be fished 7,000 meters from the sea.

"Okay, you can pass me the email. ”

"Well, wait. ”

After speaking, Jiang Chen hung up the phone, and then edited the email casually. I sent him an electronic copy of the concept map of the mining rig and how to use it.

After hanging up the phone, Yang Yuan held the phone and waited for half a minute, only to hear a buzz, and the email was transmitted to the phone.

Suspiciously opened the email, Yang Yuan browsed the electronic file sent by Jiang Chen.

At first, he was unimpressed with the mining equipment. Thinking that the boss bought the equipment without his reference, he must have been deceived by a bag and leather company that specializes in fake equipment.

But when he saw half of it, the look of shock became more and more obvious in his mind.

"This, this can't be. What are you kidding, making a sci-fi movie?" Yang Yuan muttered as his fingers kept sliding across the screen.

If nothing else, let's just say that the cylindrical mining equipment, even if it is made of titanium alloy material, it is difficult to guarantee that it will not be crushed into a ball by the huge water pressure when working underwater at such a depth for a long time. And the bowl-shaped miner that was buckled to the ground, and it didn't look like it was stress-resistant.

As for that long and narrow electromagnetic guide......

With today's materials and technology, it is simply impossible to realize this set of mining equipment!

Yang Yuan's fingers moved quickly, swiping down the document. There is a detailed record of how those offshore employees work in this document.

When he saw the last line, he was stunned.

[This document is an internal document of the Future People Group, and it is strictly forbidden to copy and circulate it without permission.] In addition to the detailed rules for offshore work, sensitive documents such as conceptual drawings of subsea equipment should be deleted within 24 hours after reading.

At this time, Yang Yuan suddenly remembered that this mining equipment seemed to be produced by the Future People Group.

"How many secrets is still hidden by this guy. Yang Yuan shook his head helplessly.

After hesitating, General Yang Yuan still deleted all the parts except for the detailed rules for maritime work in accordance with the warning content of the last line.

Standing up, he immediately walked in the direction of the door.

"Ah Yuan, are you going out?" shouted Sophie, who was preparing dinner in the kitchen.

"Well, work. Yang Yuan hurriedly put on his shoes and went out.

Although he could arrange for his employees by phone, he couldn't help but want to see the mining rig with his own eyes at the moment. It was incredible, and if he hadn't seen it with his own eyes, he thought he wouldn't be able to sleep.

Looking at her boyfriend who ran out of the door in a hurry, and the messy shoes at the door, Sophie sighed slightly and put the stainless steel basin on the kitchen table.

Although I was quite excited when I first came here, there are villas, beaches, and endless champagne and seafood. However, after a long time, she always felt that this kind of luxury away from the city was a little different from the life she imagined.

After washing her hands, she went back to the bedroom on the second floor, and lay on the bed to brush her neck.

Only by seeing the envious replies of the sisters in China can her vanity be filled a little.

But just as she was brushing her scarf, she suddenly noticed an unread private message.

"Who sent it?"

Muttering quietly, she clicked on the bubble. (To be continued.) )
