Uneasy! Su Xia rarely felt this way. He pondered for a long time, thought for a long time, and finally opened the storage space and system tasks and looked at them, but still didn't find the problem.

"What's wrong?" His eyes flickered, and he didn't know why. Is it really a cyborg? It's been almost a day, and the undersea forces of the Cybtrons must have been on the move.

Thinking of this, Su Xia stopped thinking about it, and decisively said to Sarah: "I don't want anything else in the shipwreck, go now, go to the Far North Sea!" ”

"Okay." Sarah looked calm and unflustered, and waved her hand lightly to recall the little robots that were searching in the wreck.

This time the harvest is rich enough. More than 95% of the wealth in the wreck has been taken away by Su Xia, and the rest will be allowed to slowly corrode with the sea.

Outside the sightseeing submarine, the phantom blue sea mussel saw this, and immediately transmitted a spiritual fluctuation: "I didn't lie to you, the treasure here has been taken away by you, can you let me keep half of the pearl?" ”

"Yes, give me the biggest pearl, and you can keep the rest for yourself." Susha responded to the sea mussels.

This time the treasure was beyond Su Xia's imagination, so he unilaterally changed the agreement. The sea mussel was delighted, conveying a wave of joyful spiritual fluctuations.

Sarah then took control of the capture arm and recaptured the mussel back into the submarine cabin, and watched him spit out the largest pearl before releasing him back into the ocean.

"We'll have a meeting later." The sea mussel walked happily, and the upper and lower mussel shells opened and closed, not slowly, and soon disappeared into the lonely depths of the sea.

At the same time, the large submarine in the rear, the channel in the tail slowly opened, already filled with seawater. That's the passage of return.

Sarah steered the sightseeing submarine and kept retreating, steadily retreating into the passage.

"Hum-" The hatch at the entrance to the passage closed slowly, the passage cut off from the icy sea outside. On both sides of the passage, dark blue indicator tubes lit up, flashing in the water, as if guiding the direction of the small submarine.

The speed of the sightseeing submarine in the passage slowed down, slower and slower, entered the rear compartment, and after passing several compartments in succession, returned to the compartment where the sightseeing submarine was originally placed.

With a thud, the mechanism in the compartment stretched out and connected to the submarine, holding it in place.

The water in the chamber of "Coo-Coo-Coo-......" surged, and countless small holes around and at the bottom began to drain seawater, and the water level continued to drop.

Su Xia sat in the cab, relieved, and exhaled softly. At this moment, the water outside has dropped to half.

Looking out from the cab, the picture outside the sightseeing glass is divided into two parts, one underwater and one on the water, and the water surface is gently rippling and rhythmically lapping on the glass.

"Captain, we're back." Sarah smiled lightly and said.

"Okay." Back in the big submarine, the oppressive and cold feeling gradually disappeared, and Su Xia's whole person relaxed a lot.

At the bottom of the dark sea, he always has a strange feeling that he can't control his own life and death, as if he will become duckweed in the water at any time, and be swept into the invisible unknown by the boundless seawater.

Although this large submarine is also at the bottom of the sea, the internal space is large enough to give Su Xia a sense of down-to-earth security.

"How deep are we now?" Susha asks Sarah.

"At present, it is about 1,700 meters under the sea, still located on the continental slope in the south of the continent, and is constantly diving." Sarah replied with a smile.

"Okay, the deeper, the better!" Su Xia immediately said: "The comprehensive technology of the mechanical clan is not comparable to this Nautilus, there should not be many mechanical creatures that can dive into the deep sea, the deeper the area, the lower the probability of encountering them!" "According to the description in the submarine manual, the submarine can dive to a maximum depth of 15,000 kilometers.

Now the depth, far from reaching its limit. In the dark and deep seabed, the Nautilus is like a huge black fish, under the control of Sarah, it continues to dive deeper and deeper, and the pressure on the shell is gradually increasing.

Su Xia returned to the control cabin on the upper deck, stood in front of the ring console, and continued to learn the ability to operate the submarine.

As the submarine descended, the pointers of many dashboards began to shift to the right on the console, and the amplitude of the offset gradually increased, and the displayed values became higher and higher.

2 km, 4 km...... 6,000 ...... The hands on the dial gradually shift from the safe green zone to the dark yellow zone in the middle, and then gradually move towards the final red zone.

At about ten o'clock in the evening, Sarah spoke: "Captain, we have already dived to the bottom of the sea for 10,000 meters. ”

"Okay, go on!" The feeling of uneasiness in Su Xia's heart had not yet dissipated, he rubbed his eyebrows, and without looking at those dashboards at all, he directly gave the order to continue diving.

Now, they have long since left the continental slope region and come to the real bottom of the ocean. On the other side of the earth, there are only a handful of top-notch exploration submarines that can reach a depth of 10,000 meters.

According to the map, Susha is now in the north-central part of the Southern Sea, and has not yet approached the outermost part of this sea.

Su Xia guessed that the mechanical clan should have a lot of arrangements in the outermost circle.

"Not deep enough!" Su Xia's expression was calm,

"Dive directly to 15,000 meters, and don't worry about anything else."

"Captain, fifteen thousand meters is the limit of design, this submarine should not operate at the limit for a long time, for a long time, it will cause irreversible damage to the submarine itself."

"Then go up a little bit and go as deep as you can."

"Okay, actually...... The deepest part of the seabed in this area should not reach 15,000 meters. Sarah smiled, her guess.

The truth is similar to what she guessed, the deepest area of this southern sea is more than 13,000 meters.

After diving to 13,000 kilometers, the submarine entered a relatively stable state, the pointers of each instrument panel were displayed normally, and the data floated in a stable range without any abnormality.

Under Sarah's control, the submarine has been driving its stealth ability, like a ghost at the bottom of the sea, moving alone in the vast ocean.

At such a deep seabed, there are no normal marine species in sight, only deep loneliness, darkness and coldness, and the whole world seems to be wrapped in dead silence.

Time passed slowly in the water, and before I knew it, it was three o'clock in the morning. During this period, Su Xia went offline to fill his stomach, and by the way, he went to the forum to look at various news, and saw a lot of pictures, texts, videos, etc. about the actions of the mechanical clan, and probably grasped the key points of the mechanical clan's actions.

As a person who can travel back and forth between two worlds, his biggest advantage lies in this, he can continuously obtain information from the outside world, and will not be closed by the underwater world.

"Even the mechanical creatures of the other two continents have acted." Su Xia frowned,

"Anyone else saw the legendary city of deep divers, which actually emerged from the bottom of the sea?" At the forum, there was a video that caught Su Xia's attention.

He stared, pointed, and then tapped lightly on the title of the video. [Shocked! Underwater city!

Click on the video, and you can see an extremely shocking picture. The video was shot from a top-down perspective.

In the picture, in the vast sea, a shadow so large that you can't see the boundary suddenly appears, terrifying and boundless, slowly rising, like an awakened monster, gradually rising from the turbulent sea.

The "Boom ......" waves were turbulent, the sea roared, and the majestic waves rolled away, slamming heavily against the alloy shell of the floating giant, hitting the icy splash one after another.

That's a city! It is completely different from human cities, there are no high-rise buildings, no mountains and rivers, no vehicles, and some are just patches of white and gold oval shells.

Looking down from the sky, a huge ball made of metal with a diameter of more than 10,000 meters floated out of the sea.

Only a small part of the sphere emerged, the white-gold exterior glittering in the sun, and a large part of the area was just the tip of the iceberg below the surface of the sea.

This is the end of the picture, and it is plunged into darkness. At the bottom of the video, a photographer wrote: "This afternoon, I played skydiving with a group of friends, jumping from a height of more than 10,000 meters, carrying photography equipment with me......

"Above the southern sea, we saw this amazing thing, and it must have been the legendary city of deep divers.

"Before we could fully record it, we were killed by the flying creatures of the mechanical family, and now that I think about it, it's a bit of a pity, if you can give me some more time, I will definitely be able to record all the process of surfacing the city of deep diving." The mechanical clan is divided into three forces, the sky camp, the earth camp, and the deep diving camp, which are in charge of the three continents.

These three factions are all led by the mechanical master of the Silver and White City, and they have the power to make decisions freely on weekdays, and they must report to the Silver City when they encounter important matters.

And the headquarters of these three factions has always been the focus of discussion for many players who like to explore. The city of deep diving, which is said to be in the middle of the vast sea, has been photographed with some blurry pictures before, and this time it has finally been filmed in a video.

The city of the earth is rumored to be located underground, which is normal, after all, many sub-bases of the mechanical clan are underground.

The most mysterious is the city in the sky. It stands to reason that if it floats in the sky, players can see it as long as they look up.

However, players in the Eastern Continent have so far found no trace of the city. Some speculate that the city may not be in the sky in the popular sense, but floating in the far reaches of space.

"This is the city of deep diving?" Su Xia watched the video several times, his eyes were deep, and he firmly remembered what that city looked like.

Before that, the underwater city in his mind was always associated with legends such as Atlantis, and occasionally the underwater world in the movie "Aquaman" appeared.

But the city that appeared now was completely beyond his imagination, and it was actually a giant spherical metal body.

The whole city, firmly encased in a spherical alloy shell. Only by going deep into it can you see the whole picture of this city of machines.

"Isn't this just an enlarged version of a supersubmarine?" Su Xia suddenly thought,

"It's rumored that it can move, but it's so big that it shouldn't move fast."

"The Cyborgs always say that they don't have enough resources, but they waste resources to build such a thing, and plan to build it into a mobile war fortress on the sea?" The city in the sea, from Su Xia's point of view, is really a waste.

Of course, it is not excluded that the mechanical family is to do technical accumulation and verify certain ideas. After all, underwater space can simulate space to a certain extent.

"The autonmen also want to break out of this planet......" Su Xia pondered for a moment, then activated the bracelet and returned to the submarine.

The speed at the bottom of the sea is completely incomparable to that in the air. The speed of this submarine is already quite fast, and according to Su Xia's estimate, it will take seven or eight hours to sail out of the southern seas.

These seven or eight hours are full of dangers, and you can run into mechanical creatures at any time.

"Captain, did you return to your world when you disappeared just now?" Sarah was curious, blinked, and asked Susha.

"Yes." Su Xia nodded.

"I'd love to go to your world." A hint of yearning flashed in Sarah's eyes.

"Why?" Susha looked at her.

"After all, that's what you think the real world is." Sarah smiled.

"There should be a way." Su Xia pondered for a moment,

"You are a string of data, not real flesh and blood, and you may be able to be taken out of this world."

"Really?"

"Yes, just find Blizzard and ask them for data, but ......" Su Xia paused, thinking of the many strange behaviors of the game company, and continued: "Blizzard said that they will not interfere with the operation of the game, and most of them will not agree to my behavior of asking for data. ”

"Then don't bother."

"Well, if there is a way to talk about it later." Su Xia touched her chin,

"Actually, I'd love to know what would happen if you went to Earth."

"We?" Sarah was curious.

"You, and Hal, will introduce you to each other later." In the communication between the two, time passes quickly.

The submarine was quiet, with only a slight hum of mechanical equipment, much better than the submarine on the other side of the earth, and had no effect on Susha.

Soon, the time came to half past six in the morning, and the dawn of another day arrived. A golden glow appeared at the end of the sea in the distance, like a jumping piece of broken gold in the sparkling waves.

The morning glow was awakened, and the whole world had a touch of vitality. At this moment, the operation of the mechanical clan in the southern sea has exceeded 24 hours.

"It's been a day, and the cyborg hasn't been found, so where is the masked monster hiding? There's no way he's really got into the belly of a sea beast, right? "In the outside world, countless people are questioning, puzzled, and thinking, but they can't think of how Su Xia escaped this day.

"If you can avoid the first day, you can avoid the second day."

"Maybe there are still some areas of the mechanical clan that haven't been searched, right?"

"I think he can hold out for a maximum of 72 hours......" People talked a lot, and countless eyes converged on the ups and downs of the vast sea.
