Packing up supplies or something, naturally Xu Yuan didn't need to do it himself, so seeing that there was no place where he needed help, he returned to the other side of the earth.

The deadline was almost up, and now he couldn't wait to see the results of the engineering robots.

If the mining matter is solved as soon as possible, Yuanying International Mining can start construction as soon as possible, and the virtual helmet should be put into production as soon as possible.

After coming out of the villa on the main island, Xu Yuan drove a speedboat to the desert island alone.

As soon as he got close to the island, he realized from a distance that the dock built on the shore had been completed.

The main body of the building is a concrete wall, the top is shaded by a tin shed, and the interior is a "concave" sink.

In terms of scale, this small dock can only be described as small compared to those dry docks that are hundreds of meters long.

However, although it is a little smaller, the structure of a dock is still very comprehensive, and if it is necessary in the future, it can be widened again, right?

After parking the speedboat, Xu Yuan got on and walked straight to the material storage point.

I saw that the two engineering robots were standing next to the in-situ material point and waiting, and after completing the construction task, they would automatically go into hibernation.

Building materials such as steel, cement, and sand are almost consumed.

After taking inventory, Xu Yuan recycled the remaining building materials, and then walked to the drone terminal placed in the jungle again.

I saw that the honeycomb-shaped drone terminal stayed there very quietly, most of the drones were parked on the charging station and waited, and a few were cruising on the beach outside the jungle.

After checking the drone's reconnaissance records and confirming that no one was near the island, Xu Yuan walked in the direction of the dock.

Pulling open the hatch, he saw the deep-sea submersible floating on the surface.

The teardrop-shaped hull has a smooth and flat shell, and the water intakes at both ends of the rear side continuously feed water into the engine for boosting.

At the same time, the rear end water nozzle sprays high-pressure water flow, which produces the squeezing effect of water pressure difference in the tail inclined shell, and the dual effect of the rear end water jet propulsion, which can make the submersible surpass all submarines in the world in terms of speed.

The front end of the submersible is equipped with two pairs of robotic arms for deep-sea construction, and at the bottom hangs a slender cylinder, which is a mining module, which has been assembled by engineering robots and can be operated with electricity.

The energy consumption of the submersible is the source crystal, and the built-in molten salt electrolysis reduces carbon dioxide device, which can theoretically maintain the normal oxygen supply in the submersible as long as the energy is sufficient.

Jumping to the top of the submersible and feeling the swaying of the soles of his feet, Xu Yuan cautiously squatted down, and then groped for a device similar to a camera at the top.

Turning his eyes over, Xu Yuan said in a deep voice.

"Start."

"Iris verified, welcome, Captain."

A gap slowly cracked one meter in front of Xu Yuan, and a passage to the cabin appeared.

Leaned over to take a look, and after confirming that it was safe, Xu Yuan jumped in.

After entering the cabin, Xu Yuan looked around in some surprise, and it was hard to imagine that looking from the inside to the outside, it was as if it was transparent.

No, it's not transparent, it's like some kind of holographic projection device!

At this moment, Xu Yuan suddenly had a strange feeling, standing in this submersible, he felt as if he was in a huge transparent bubble.

After sighing at this spectacular scene, Xu Yuan passed through a narrow hatch again, entered the cockpit directly, and sat on the captain's seat in the bow.

"Captain please name the submersible." The polite electronic sound sounded, prompting Xu Yuan how to operate.

After thinking for a moment, Xu Yuan said directly: "Miner No. 1." ”

"Okay, Miner 1 is at your service, please follow the operation guide ......"

There are no complicated buttons, and with the help of rudimentary artificial intelligence, even one person can be competent in driving equipment that requires multiple people to complete.

After getting familiar with the operation, Xu Yuan immediately gave the command to go to sea with voice control.

Hearing the slightest sound of water behind him, the entire submersible sped out towards the vast sea outside the dock.

Looking at the waves flying around, Xu Yuan suddenly had a feeling like surfing, and after getting used to it for a while, Xu Yuan ordered again: "Dive, 500 meters." ”

"Roger."

As soon as the electronic sound sounded, the submarine slammed down, as if submerging its head in water, and the sound of the waves around it instantly disappeared.

Xu Yuan paid attention to the meter at hand, the symbol indicating the depth continued to beat, and finally stopped at a position of 500 meters.

Taking a deep breath and holding back the excitement in his heart, Xu Yuan set the coordinates of the offshore mining platform on the slab.

Then, he took a deep breath, a hint of excitement in his tone.

"Miner 1, set sail! Let's go mining! ”

"Yes, Captain."

Heading towards the deep blue seabed, Miner 1 galloped away,

Because of its swordfish-like shape, the submarine has almost no resistance when navigating through the water.

The rocky reef, the dark green seaweed, the colourful fish scurrying through the sea, and the jellyfish and squid dancing to the accompaniment of bubbles are all visible on the walls of Miner One.

In addition, Xu Yuan also saw the legendary giant octopus

When Miner No. 1 passed by it, the big guy chose to ignore it as if he didn't see it, and when he turned around, he shook his arms and legs and disappeared into Xu Yuan's sight.

As the depth increases, the light from the surface of the sea becomes darker and darker, and the dark blue claustrophobic feeling becomes more and more obvious.

Xu Yuan wasn't sure if he had deep-sea phobia, but he turned off the cameras around him, leaving only the perspective in front of him.

At about 8,000 meters on the bottom of the sea, it takes about two hours for the submersible to reach here, and seeing that there is still a while, Xu Yuan got up and walked towards the living module.

The living compartment is compact, with two beds with nylon buckles on the left and right sides, and if the bed is lifted, the table and wardrobe under the bed can be pulled out.

After examining the internal structure of the submersible with great interest, Xu Yuan instructed the submersible to wake him up when it arrived at the location, and then got into the sleeping bag-like bed and took a nap.

About an hour later, under the soft sound of the bell, Xu Yuan opened his eyes.

After getting out of bed and returning to the cockpit, he turned his gaze to the control panel, his eyes widening in surprise.

At 8,000 meters under the sea, it is already all dark!

Unknown plankton emit a faint glow and move slowly across the ocean floor.

It seems that the surrounding environment is deep and quiet!

In addition to those strangely shaped underwater creatures, the cracks in the rock crust of the seabed spewed scorching bubbles from time to time, and the dark red firelight, like a volcano, brewed terrifying energy.

At this time, a strange underwater creature more than ten meters long slowly approached the side of Miner 1.

It looked at Miner One curiously, and even touched it with its mouth, but soon it swam two meters away as if it were electrocuted, and escaped without looking back.

The electrostatic drive on the surface of Miner 1 can make most deep-sea creatures lose interest in it, both to protect the safety of the submersible and to protect the safety of these seabed creatures.

Without continuing to play, Xu Yuan quickly controlled the submersible manually and moved to the top of the tin ink mine according to the distribution of mineral resources marked on the map.

"Throw the mining module." After confirming the location of the target, Xu Yuan ordered in a deep voice.

"Yes." The AI replied politely.

Soon, the circular device suspended at the bottom separated from Miner One, and a series of narrow strings of bubbles exited from the back of the cylinder, propelling the cylinder towards the target rock.

Within a few seconds, the circular device slowly stopped above the rock formation under the sea, and the engine behind it slowly turned off.

At this time, Xu Yuan glanced at the map on the screen, and saw that the green dot marking the direction of the submersible had coincided with the red dot in the center of the mine.

Seeing this, Xu Yuan immediately ordered: "Mining module, unfold!" ”

In the next second, I saw the circular device slowly unfold, and the hatches on both sides slowly expanded outward, releasing two objects like awls.

After separating from the circular device, the two awls immediately began to sink, and a string of water mist erupted from their tails, pushing the tips into the bottom of the sea.

The awl's head dives deep into the rock, and then a miracle happens!

The tail of the awl burst suddenly, exploding a string of bubbles at the same time, like an umbrella, opened an arc-shaped top cover with a radius of about ten meters, and the top cover slowly descended and buckled onto the flat seabed rock mass.

"The mining module has been deployed, please deploy the transport module."

The polite electronic sound sounded again, pulling Xu Yuan back from the shock of technology.

The so-called transport module is actually four guide rails and an ellipsoidal lifter.

Due to the large size of these things, Xu Yuan did not carry them in the submersible, after all, there is such a thing as storage space, and it is really easy to bring objects to the bottom of the sea.

After stopping Miner 1, Xu Yuan immediately came to the conveyor port, and then put the guide rails and other items in the storage space outside the cabin.

The robotic arm began to swing automatically, grabbing the rails and other building materials to assemble automatically.

The rest of the things don't need Xu Yuan to do by himself, he only needs to wait for the construction to be completed and then return to the ship.

A circular track 7,500 meters long transports ore collected from the seabed to a shallow location.

When the minerals are delivered to a shallow sea at a depth of about 500 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 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 refinery of Yuanying International Mining for refining.

It's that simple, but some of the things are really expensive!

The cost of 3 million yuan crystals really made Xu Yuan feel a little difficult.

However, it is also worth it, at least from now on, there is no need to plead with others for tin ink ore or something.
