At the same time as Tang Shuxing unfastened the lock, he subconsciously looked at the depth gauge on his wrist, this gauge was synchronized with the dive module gauge, and the depth displayed on it was 670 meters, he was taken aback at that time, and subconsciously said: "This lake in the Aral Sea is more than 600 meters deep!?" Is there a problem with the meter? ”

Ji Kefeng and Gu Huaiyi shook their heads at the same time, and Ji Kefeng said: "The reason why we have been wandering for so long and not going down is that it is too deep, and the position we are in now is in a cave in the center of the Aral Sea Lake, but this water hole is very large, with a diameter of nearly forty meters. ”

"Strictly speaking, there are many such holes at the bottom of the Aral Sea Lake, each of which is about the same diameter." Gu Huaiyi added on the side, "Without equipment, it is impossible to dive. ”

Before departing from Shandu, they were told that the average depth of the Aral Sea was only about 10 meters, and the deepest place was no more than 70 meters, which was just enough to reach the depth of conventional diving, and they could dive to this depth under the premise of wearing civilian diving suits. However, their current depth is no longer suitable for conventional diving operations, and they can only take the way of saturation diving, but they are facing great danger.

The Asia-Europe troops did not take them to dive in the form of diving bells, nor did they let them enter the pressurized cabin when they entered the diving cabin, but made the diving cabin, which integrates various functions such as decompression and diving bells, to increase the operation time and improve the operation efficiency.

After leaving the fixed frame, they walked towards the isolation hatch at the bottom one by one, and the isolation cabin could only enter 5 people at a time, and they had to leave the diving cabin in batches of 3 times.

The butcher captain climbed down, looked at Tang Shuxing and the others and asked, "Do you have any experience in deep-sea diving?" ”

Gu Huaiyi and Qianhu nodded flatly, Tang Shuxing and Ji Kefeng had never dived to such depths.

"Okay then, let my team go out first, go out two first, see how it goes, and then go out in batches. The four of you left with my team in two separate parts, do you understand? The butcher captain gave the order, and the four nodded in understanding. Immediately after that, the butcher captain asked everyone to check each other's equipment and communications.

"Do we have weapons?" Ji Kefeng asked.

The butcher captain looked at Tang Shuxing and Gu Huaiyi's cold weapons and said, "Don't you have them?" ”

"Automatic weapons." Chitohei corrected.

"The normal depth of use of underwater rifles is up to 60 meters, and even if the gun is fine beyond 60 meters, the bullet will not be fired." The butcher captain shook his head and said, "At this depth, we can only pray that we don't encounter anything, because even if we fight, our arms can't swing properly, and it's luck to be able to swim or walk underwater, but we do have weapons and equipment." It's all in the safe box, provided that we enter the weird quad in front of us and find a space where we can move freely before we have a chance to use them, of course. I don't want to use weapons, and I pray that it will go well. ”

As he spoke, the butcher captain commanded his two men to enter the isolation cabin, then locked the door, pressed the water entry switch, and then pasted it to the only window next to it that could see the left side, and pressed the intercom and said, "The situation outside is good." The visibility was about 10 meters, and no suspicious objects were found, so you could go out. ”

The hatch outside the isolation chamber was sprayed open, and a mist of water sprayed out, splashing the mud and sand at the bottom of the water. The two team members slowly swam out in the mud and sand, because of the pressure. The speed of swimming is very slow.

"Good, the wetsuit can handle the pressure, and we're now moving towards the goal." The soldier replied, turning his head and giving a thumbs up to the captain in the window, before moving on.

"Why isn't there a forward aid?" Tang Shu asked the butcher captain. "If you go on like this, it will take a lot of time."

Captain Butcher explained, "Do you know why they managed to get a dive pod in such a short period of time? It's because the overly sophisticated instruments will be destroyed at this depth, but it's not a matter of water pressure, it's something else, they describe it as something like electromagnetic waves, we've put deep-sea robots before, and those iron things can dive to a height of thousands of meters in the sea at the deepest, but when they get close to the cube, they break down inexplicably, and they float up directly, and then they try seven or eight times repeatedly, and they all fail, so we can't use thrusters or anything like that, we can only swim or walk, Fortunately, communication equipment can still be used, but only to a limited extent. ”

After listening to this, Ji Kefeng hurriedly asked: "In other words, we have lost contact with the water?" ”

"Of course, a few hundred meters underwater, even if it is a submarine, ordinary communication has to put buoy antennas, and now laser communication is not fully popular." The Captain Butcher kept his eyes on the outside as he spoke, and by this time the two men were almost out of the range of visibility, and the captain shouted again, "Report on your situation every five meters." ”

"Okay." The soldier in the water replied, "We are still about thirty-five meters away from the target visually, there is no laser ranging, but there is almost no refraction at this depth, and the estimated distance should be accurate and not deviate much." ”

"Received, after you get to the target area, find the entrance and exit or other places where you can live, and the second group will set off." The butcher captain turned his head to look at the others, "I heard it, there should be no problem, the second group of people should prepare." As he spoke, the butcher captain looked at Tang Shu again and said, "You are also among the second group of people, go to 4, 2 of my team members, and 2 of your people." ”

Ji Kefeng and Gu Huaiyi didn't speak, Tang Shuxing knew that the two of them must be all the way, so he looked at Qianhuping, Qianhuping nodded to indicate that he understood, and then slowly climbed down and waited at the isolation hatch, and the other two soldiers also immediately went down and waited there.

At this time, the captain handed the two boxes to the two soldiers and patted: "This is a weapon, in order to save space and facilitate carrying, it is all parts, you need to assemble it yourself, there are not many ammunition, but they are both armor-piercing shells and incendiary bombs, hey, pay attention to that Chinese." ”

Tang Shuxing looked back at the butcher captain, and the butcher captain pointed at him and said, "Don't play tricks, cooperate well with my people, otherwise I will definitely break you down into a hundred pieces!" ”

Tang Shuxing nodded silently, and at this time, the reply of one of the two soldiers who left came from the communicator: "Sir, we have reached the bottom of the target object, and we can't see the entrance and exit in all directions, there are a lot of algae, colorful, very beautiful, I don't know if it's a mutated thing." ”

The butcher captain immediately asked, "Did you find anything alive?" ”

When the captain said this, everyone subconsciously looked at him, because at this depth, it was almost impossible to have anything alive, and this was not a sea, but a lake.

The soldier also seemed to be deeply surprised by the question of the butcher captain, and after a pause of a few seconds, he observed for a while, and replied; "Nothing was found, except that the algae was algae, which covered the lower part of the cube, and we decided to peel it off."

"Be careful!" The captain looked nervously into the distance, even though he couldn't see anything.

The two soldiers slowly approached the algae, slowly picked it up with their hands, saw the side of the cube that fell into the dirt at the bottom of the water, and carefully probed with their feet, who knew that when their feet reached over, the soil below suddenly relaxed, and then collapsed downward, and the collapsed soil was loosened and floated upwards, the speed went from slow to fast, and soon saw that there was a gap in the cube next to the dirt that did not know the width, but was at least one and a half meters high.

The soldier immediately reported the news to the butcher captain, who hesitated for a long time and said, "Volunteers are needed, who wants to go in, it seems that there is an entrance and exit." ”

The two soldiers glanced at each other, and the man on the right pointed to himself and said, "I'll go, I have the most experience in the team." With that, the soldier did not hesitate, but swam down, crossed his body, and crawled into the ditch with the help of another man.

"It's dark, there's no line of sight, I don't dare to turn on the underwater lights for fear of bursting, and the pressure in this area feels stronger than outside." The soldier replied as he groped his way forward, and though his tone was calm, he was actually extremely nervous. With the cold water and zero line of sight, no matter what kind of training you have, you can't be completely calm, and it's very good that he can do it to this extent.

After a long time, the soldier finally saw the faint light, he accelerated his swimming and crawling speed, and then drilled out from the other side of the ditch, as soon as he drilled over, his head left the water, at that moment, he thought it was an illusion, and he gestured up and down with his hand, and found that it was really above the water, and he seemed to be in a gutter.

The soldier was still suspicious, and climbed up to the edge of the gutter with difficulty, stood there and looked around, and found that above the gutter was a passage, and the passage could advance three people in parallel, which was spacious, but the passage was full of a strange gas, I don't know if it was the refraction of light in the channel, and the gas looked colorful.

"I went ashore, I don't know how to describe it, anyway, out of the water, in a corridor, it should be in a cube, it is full of colored gas, I don't know if it's a problem with the light source, I can turn on the detector now." The soldier said, took off the decompression bag on his body, took out the instrument kept in it, and then tested it, looking at the indicator and said, "It is a breathable gas, the oxygen content is extremely high, more than 65%, and it cannot be exposed to this gas for too long, otherwise it will cause oxygen poisoning." ”

The butcher captain smiled: "It's okay, as long as it doesn't take more than 24 hours, at least the oxygen cylinders we carry will not be wasted, and there is no need to worry about breathing problems, the second group of people is ready to go!" ”

The water in the isolation cabin had been drained out, Tang Shuxing, Qianhehei and the other two soldiers got into the isolation cabin, and at the moment when they were about to close the door, the butcher captain blocked his hand and thought for a while: "I'm with you." With that, he turned to one of his soldiers and nodded, and he himself got into the isolation pod.

At the moment when the water in the isolation cabin was slowly filled, Tang Shuxing didn't realize what was going to happen next, and the team collapsed in an instant.
