With the rumbling sound of water, the Jiaolong sank into the sea. However, in the titanium alloy bulkhead in the cabin, Song Wenbin couldn't hear any sound, and could only see outside the bulkhead, where bubbles kept floating.

The scale pointer in the bulkhead shows the depth of the submersible's dive, and in just a dozen seconds, the Jiaolong has dived to a depth of 200 meters, far exceeding the maximum depth that a human can dive.

Before entering the deep sea, Song Wenbin was a little nervous, but when all this happened, he felt that it was nothing, so he patted Sutina's hand on his arm and said softly: "Let go of me, it's not too late for you to pull me when you really want to die." ”

His tone was very relaxed, infecting Sutina, and after Sutina secretly pinched him, she slowly let go of her hand, turned to hug her knees, and sighed: "I really hope that the one below is really a shipwreck, so that we can be regarded as worthwhile." ”

"It would be nice to get down to the point safely."

Song Wenbin looked at the decreasing numbers on the scale and muttered, "I hope I don't bump into any deep-sea beasts or anything." ”

"I'm going to die!"

Su Tina, who just felt that she was a little safe, was angry and wanted to arrest him, but Song Wenbin immediately warned: "It's very small here, don't move around." ”

"Can you stop the crow's mouth....?" Sutina restrained her voice and complained dissatisfiedly: "I'm already nervous..."

"I said, I'm more worried about oxygen here than any other animals." Huo Yu said with some worry: "The space here is so small, will we die of lack of oxygen?" ”

"No, there's an oxygen cylinder in there." Sutina said confidently, enough for us to work for five hours.

After thinking for a moment, Huo Yu looked at the confined space around him and asked, "Then what about the carbon dioxide we exhale?" ”

"I don't know." Su tina muttered: "I was sucked away by Song Wenbin." ”

Huo Yu was stunned for a moment, and couldn't help but laugh.

"Hey!" Song Wenbin was annoyed: "If I suck her carbon dioxide, won't you suck my carbon dioxide?" Is there a need to divide the high and low at this time? ”

Sutina blushed inexplicably, took a sip and said, "Who's going to suck your carbon dioxide." ”

As soon as she finished speaking, Sutina herself couldn't help but laugh, as if suddenly she had forgotten that beneath her ass was the unfathomable Java Trench.

Song Wenbin always felt that the two colleagues were laughing inexplicably, and he warned: "You'd better really talk about carbon dioxide." ”

As a result, Huo Yu laughed even harder, leaning forward and back in the cabin.

"Xiaomao, can you be serious!

”

Song Wenbin said loudly: "Is our voice going to reach the mother ship, and maybe even to the command center in China?" ”

However, his words did not stop the inexplicable smiles of the two colleagues.

Huo Yu even openly made a vomiting sound in the cabin, "Vomit..... I don't want a misogynistic part of me to stay in my body. ”

"Haha....."

Song Wenbin couldn't hold back his laughter, and after laughing, he said angrily: "Is there a mistake!"

This is the Java Trench in the Indian Ocean, shut up quickly!

！ ”

Sutina finally remembered where she was, and she forcibly covered her mouth, her face flushed.

There was no doubt that the sound reached the control center of the mother ship far away at sea. In the control center, a group of forty or fifty-year-old men covered their heads one after another, wanting to laugh but not daring to laugh, holding the microphone and wanting to speak.

To be honest, they have worked for decades and most of the time they only laugh when they complete the project, and even the young people in the same unit are always nervous at all times, and no one dares to be as unbridled as these three strange guys.

"What is the depth now?"

The captain couldn't help but ask knowingly, he really didn't want to see these three people play treasure anymore.

Sutina hurriedly put down her hand and said, "781 meters." ”

"Okay, take a look around."

"Jiaolong understands." Sutina replied.

Huo Yu finally stopped laughing, Song Wenbin secretly glared at her, and whispered, "I've lost my face." ”

Huo Yu glanced at him indifferently and snorted lightly.

After being reminded by the captain, Su Tina didn't joke with Huo Yu and Song Wenbin without shame, but the captain asked them to look outside, and there was really nothing to see. After a depth of more than a thousand meters, it was completely dark outside, and it was no different from the universe, and there was water everywhere up and down. Except for the numbers on the scale, which are still changing, everything else is the same.

Originally, Song Wenbin still had the idea of seeing if he could see deep-sea creatures, but with the breadth of the sea, the probability of encountering deep-sea creatures in diving is undoubtedly similar to the probability of encountering a planet in space. If it weren't for the row of unknown searchlights at the bottom of the boat, they wouldn't even be able to see the bubbles in the water. Even if there are headlights, all you can see is seawater, bubbles, some floats, and that's it. Even if the searchlights illuminated some possible marine luminescent creatures, those glowing creatures would quickly flee the falling Jiaolong, making it impossible for the ship's probes to catch their ghostly figures.

This made Song Wenbin feel a little unbelievable in a trance, he felt that there was some imperceptible deep meaning in it, which could squash the incomparably majestic power of conventional nuclear submarines, but for these creatures living in it, it seemed as if it did not exist. They can swim freely in it and survive. Even if one day he could become one with these deep-sea creatures, with this majestic power?

The thought in his consciousness flashed, and the silence of the deep sea magnified his thoughts, and by the time he came back to his senses, the Jiaolong had sunk to a depth of more than 1,000 meters.

After another half an hour, it descended to a depth of 2,000 meters, but it still did not reach the end at all, and even half of the road was not completed, and after another half an hour, it descended to a depth of 4,000 meters. The Jiaolong is still working steadily, and there is nothing abnormal in the slightest.

Since the ship wasn't controlled by them, there really wasn't much to do while sitting inside. Su Tina, who had been silent for an hour, couldn't hold back a little, she gently took Huo Yu and asked in a low voice, "Hey, Huo Yu, why did you want that day..."

Huo Yu was startled, looking at Sutina, not knowing why she suddenly asked her such a question in the Infernal Deep Sea.

But Su Tina's expression was very concerned, Huo Yu knew that he couldn't get around, and his expression became a little dark: "When I'm very emotional, it's easy to ......"

"Shhhh

Song Wenbin interrupted Huo Yu in a low voice, maybe Su Tina was still incomprehensible about Huo Yu suddenly biting him that day, but now was not the time to ask such a question.

"Take a good look."

He said to Sutina with some sternness.

"But that's really scary." Sutina whispered, "That really scared the hell out of me. ”

"I ....." Huo Yu seemed to want to say something.

But Song Wenbin didn't want the two of them to continue the topic, he didn't want anyone outside the show to know about Huo Yu's uncontrollable weird impulses. Song Wenbin, who has been immersed in the Internet for more than ten years, clearly knows that in this era, any outrageous action will be criticized by countless Internet moral pacesetters, even if the joke they just made will be sprayed by someone with a heart on the Internet, Song Wenbin will guess what they will say, and they will definitely joke regardless of the occasion. He knew more clearly what kind of criticism would be aroused if Huo Yu's bite was known by good deeds, but that was not what he wanted to see.

"It's only 4,000 meters, what's scary, I remember, no one in the United States has dived into the Mariana Trench...."Song Wenbin said left and right.

Huo Yu glanced at him and tacitly didn't speak.

"Do you mean the American Trieste 2?"

Sutina's attention was diverted, and she said like a treasure: "Yes, that ship can indeed dive to a depth of 10,000 meters, but it's a pity, that ship has no operational function, in fact, only Jiaolong can operate at a depth of 7,000 meters in the world." ”

As she spoke, Sutina began to talk to Song Wenbin about the characteristics of various submersibles again, from Trieste 1 to James Cameron, and talked a lot, until there was a crackling sound from the roof of the Jiaolong.

The conversation stopped abruptly, they seemed to be unintentional, but in fact, they all had a string in their hearts, on the scale, the depth had come to more than 4,700 meters, once the submersible had an accident, the water pressure would kill them in an instant.

"Mother... Mother ship.... We.... We heard the voice....."

Sutina said in fear, grabbing Song Wenbin with her palm.

Song Wenbin was also terrified in his heart, and the cracks, cracks, cracks outside the submersible were terrifying, as if a water ghost was gently knocking on the door of the submersible outside.

"It's okay, it's the pressure-resistant shell is bearing the load, everything is normal."

The voice on the mother ship returned to the Jiaolong.

Even so, Song Wenbin felt frightened enough, in such a quiet environment, all psychological activities are infinitely magnified, and after going to so many countries and regions, the environment here is undoubtedly the most extreme and terrifying.

"We.... How far are we from the goal? Sutina stammered, honestly she wanted to get out of the silence and horror as soon as she was done.

"It's about 300 meters away, but there may be a seamount there. We're going to slow down. The voice on the mother ship replied.

"Understood." Sutina said.

As he spoke, the bright searchlight on the bilge had already shone on something, and it was the first time that Song Wenbin saw something other than seawater and floats on the screen in the cabin. He sat up straight, staring intently at the screen.

Unlike the shallow water, there is not much sediment here, but there are many strange rocks, some of which look like giant sugar gourds, piled up in the deep ocean.

"There's still a lot of geological activity here.... I hope there won't be any earthquakes and volcanic eruptions or anything like that....." Sutina looked at the screen intently, her mouth constantly fragmented.

Song Wenbin thought that she didn't need to scare her, she could scare herself to death.

"Depth 4820, flow rate 0.2, water temperature -0.5 degrees Celsius, robotic arm, normal, engine, normal, voltage, normal. Sonar system, normal. 312 meters from the target point. ”

The voice of a ground worker came into the cabin, it was a female voice, which was very rational and reassuring.

"Roger." Song Wenbin replied.

As the submarine continued to descend, Song Wenbin could finally see what was on the screen, which was the top of the submarine mountain illuminated by the searchlight. It is very unbelievable that they are at the bottom of the sea at a depth of nearly 5,000 meters, under incredible water pressure, but at the same time, he is at the top of the submarine peaks, flying over the tops of those peaks like flying machines.

Under the searchlight of the Jiaolong, Song Wenbin could see that most of the cliffs on both sides of the seamount are asymmetrical "V" shapes, generally with a stepped landform, with the upper part of the gully slope being gentler and the lower part steep. The average slope is 5 degrees to 7 degrees. Occasionally, you will encounter a slope of more than 45 degrees.

Every now and then, the Jiaolong would stop, then change direction and fly around the top of those underwater mountains.

Extreme environments in the deep ocean. Seamounts, reefs, trenches, and all kinds of complex terrain are hidden in the dark, and the only obstacle avoidance technology that manned submersibles can rely on when diving is collision avoidance sonar. Collision avoidance sonar is a device used to detect obstacles in water. It is installed around and below the submersible, and the maximum distance can reach more than 100 meters.

It didn't take long for them to reach the target area directly above the target area, under the control of sonar and sea surface control center.

The three people in the metal cabin couldn't sit still, they sat up straight one by one, staring at the illuminated area of the screen with wide eyes. After many years of hard work and travel, can they really see the super treasure that was lost hundreds of years ago?
