For 03 and the military doctor's side of the gradual unfolding of the action against a few newly discovered 'clock tower' underground industries, they can only be in a hurry, after all, they are in the depths of the ocean, even if they want to return to the shore, it will take a few days, not to mention that they have to complete this tracking mission, although this mission is boring, but they have no reason to refuse, because in this case, except for them, I am afraid that no one else can complete this mission.

"I don't know why, for the past two days, I've been worried that I will suddenly sink to the bottom of the sea and never get up again." The ghost said, "How long will it take to sink to the end of this bottomless place?" ”

"As the world's second largest ocean, the Atlantic Ocean occupies nearly 20 of the earth's surface area with an average depth of 3,627 meters, and the deepest Puerto Rico Trench is 9,219 meters deep. "If you want to go deeper, you have to go farther, although it is a deep-sea dive, but at least we have not reached the real depths of the ocean, it is just a coastline far away."

"Aren't we still far from a deeper place?" The ghost asked.

"It's nowhere, it's early." Cuttlefish said.

"Have you seen anything strange in the sea?" The ghost asked.

"Of course I have seen it, this is normal for people who often go to sea." The cuttlefish didn't know where to get a bottle of wine, and said as he drank it.

"What's so strange about it?" The ghost immediately became interested.

"In a submarine, even if you encounter something weird, you can't see it with your own eyes, you can only roughly judge the size of the thing from the dialback, I once saw an echo as big as a cruiser in his usual life, and it was at a depth of 700 meters in the water, when our submarine dived to a depth of 390 meters, and the speed was 28 knots, and that thing skipped under us, the speed was scary, if I hadn't seen it with my own eyes at the time, I didn't believe it, the result of the equipment analysis was that the speed of that thing should not be below 50 knots, It was deep underwater, and although it was huge, we couldn't see it at all, and it passed before we could even react. ”

"Is it alive or is it a machine?" The ghost asked.

"It's too fast, we don't have time to do anything else, but judging from experience, it shouldn't be a machine, and besides, there is no machine in the world that can run so fast underwater, but if it doesn't live, it's too big." The cuttlefish said, "It is impossible for a whale to swim so fast, there are still a lot of things under this water that we have not seen, run outside long enough, you will see all kinds of strange things, we have suffered an inexplicable attack in the process of sailing, it happened without warning, the submarine suddenly shook violently, we also checked, and there was no real problem, just as it hit a whale or something, after all, nothing serious happened, you said we will continue to sail normally, But when we returned to port, we found that there was a big crater on the shell of the submarine, which was located on the top of the submarine, and it could not have been hit, and the shape was extremely strange, like the paw prints of some webbed animal. ”

"How is that possible? The hull of the submarine is quite strong, how can it be smashed into a mark? The ghost didn't believe it.

"If I hadn't seen it with my own eyes, I wouldn't believe it, it was like a child's handprint on plasticine, clearly recognizable, and according to the size of this mark, the size of the thing is probably about the same size as a submarine." "So I've always hated going to sea to do ocean diving, not because I'm afraid of these things, but because I don't want to face too many unknowns, I have a mild deep-sea phobia, after so many years, I think I've healed myself, but this time I came out, I found that it didn't, but don't worry, it doesn't affect my judgment." ”

The submarine No. 8079 did not continue to move in one direction as they expected, but changed direction several times and headed for the other side of the Atlantic, never moving at full speed from beginning to end, always maintaining a speed, just like walking in the sea, they could only be patient and follow from a distance, judging from the performance of the other party, they should have followed behind before they were noticed, but they still did not dare to take it lightly, and they kept following cautiously.

"These people really don't have any sense of time at all, they are grinding, and they don't have fun doing anything, so do they have to run out of fuel and dock at the shore?" The ghost is no longer in a hurry, it's not that he wants to open it too much, but he has no strength to hurry.

"People walk like this, naturally there are people's truth, just follow it, anyway, their fuel can't last long, I don't believe they will wander like this until the fuel is exhausted, and then suspended in the sea without moving, isn't that just looking for death?" The cuttlefish's patience has been exhausted, and he has no strength to lose his temper now.

"Can you do the math? How long can they toss in the sea? Heavy Punch asked.

"Although I don't know the model of this submarine, based on the size and regular fuel storage, they can still sail in the sea for a maximum of three to five days, of course, at the current economic rate, if the speed is increased or their fuel storage is less than I expected, it will probably be about two days, but the location here is far from any coastline, it is impossible to reach in two days, and the nearest one will take four and a half days to arrive, so their fuel should last five days, of course, this is just my inference, I don't know exactly what the specifics are. "The cuttlefish analysis is quite thorough.

"In other words, we will have to toss around in this sea for at least four or five days." The ghost rubbed his face, "Then do we have enough fuel?" ”

"If nothing else, it should be enough, but if there are other emergencies, it's hard to say." Cuttlefish said.

"What's the emergency? Are you still worried about being attacked? "The ghost didn't understand too much.

"There are too many emergencies in the ocean, and an attack is just the most common of them, as well as some unknown biological threats in the deep sea, complex water ripples in the ocean, such as sea cliffs, undercurrents, reef groups, and even the simplest, the enemy's acceleration will cause our fuel consumption to increase, but you must know that in addition to this, the others are quite deadly threats." Cuttlefish said.

"What is the Sea Cliff Road?" The ghost didn't understand.

The cuttlefish pondered for a moment, and after thinking about how to explain clearly, he explained, "How do you say this?" If the seawater thermocline is in a state where the density of the upper layer is high and the density of the lower layer is small, a negative density gradient jumper layer is formed, and the buoyancy of the seawater decreases sharply from top to bottom, which is called "sea break cliff". The effective depth of most conventional submarines is 300 meters, and when the submarine falls below the safe diving depth uncontrollably, it will be destroyed by the huge seawater pressure, resulting in the wreck of the sea cliff. ”

"Damn, so mysterious?" The ghost listened in a straight cold sweat, "Does this happen often?" ”

The cuttlefish nodded, "Of course it won't happen often, but the possibility of encountering this situation in some unexplored areas will increase infinitely, and once it appears, it is almost irreversible, we are now in a blank area of detection in the deep sea, and no one knows the water ripples here, so it is likely to encounter this kind of trouble, the most famous such incident is the 1963 "Thresher Shark" attack nuclear submarine when it dived 300 meters at the edge of the continental shelf. It suddenly sank to the bottom of the sea at a depth of 2,300 meters for no apparent reason, taking the lives of 129 crew members on board, causing the biggest tragedy in the history of submarines and becoming the world's first wrecked nuclear submarine. Although there are many speculations about the cause of the ship's wreck, one of the main theories is that the boat encountered an unevenly dense jump layer underwater, which caused internal waves that caused the submarine to suddenly fall and sink into the deep sea and be crushed. ”

"Have you ever been in this situation?" The ghost asked, but as soon as the words came out, he felt that it was wrong, if the situation was so special, then did all the submarines that had encountered this situation not make it back alive?

"I'm lucky, but I've had close contact with this kind of place, it was a few years ago, but two submarines were diving at the same time, and one of us in front of us suddenly fell, we found out about this situation in time, slowed down and stopped, but then ......" The cuttlefish shook his head and didn't say any more, obviously touching his sadness, as for the ending, he didn't want to talk about it, but it shouldn't be the result he wanted.

"So you're not too worried about that we're going to have this happening." Heavy Punch said suddenly.

"Why do you say that?" Meryu glanced at him.

"It's very simple, someone has a way for us, if they encounter this situation, we can avoid it in time, but you may consider that since they dare to rampage here, they should know the situation here, so it is likely that the submarine in front is familiar with the underwater situation here, so you don't worry about running into such a big trouble." Worm said.

"Kind of makes sense." The cuttlefish nodded, but did not acknowledge.

"Has the storm stopped outside?" The ghost asked.

"Not yet, what do you want to do? Going out in the sun? The cuttlefish asked.

"Just asking." The ghost is actually quite boring.

"They're turning again." The sonar soldier reported.

"Turned again? Where exactly do they want to go? "The ghost is a little confused.

"In fact, the reason why they keep turning may not be the aimlessness we guessed, it is likely that they are moving along a certain underwater channel, in the depths of the ocean, it is impossible to detect all the areas clearly, it is very likely that they have discovered a certain waterway in the early stage, and now they are moving along this waterway, after all, it is quite dangerous to detect a new waterway in the depths of the ocean, so they would rather spend more time walking, at least to ensure that nothing goes wrong." The griffon said.

"It's possible, and it's very likely." The cuttlefish nodded, agreeing with him.

"That is to say, they are like being in a desolate area, moving along a detour, although everyone knows very well that this road is not easy to walk and takes a long time, but at least it can take them directly to their destination, although everyone knows that if they go directly through the desolate area, they are likely to arrive faster, but there may be more threats in it, so they don't dare to take risks, right?" The ghost probably understood what they meant, so he described it in more concise terms.

"You have a strong comprehension?" The cuttlefish said with a slight sarcasm.

"Of course." The ghost didn't understand what he meant.

"But where are they going in the end? This is indeed a problem. "Heavy punches feel that this is a long way away, and it is really uncomfortable.

"Oops, it's time to eat." The ghost looked at his watch and got up and walked back.

"Give me a hot box can." Heavy punch said.

"Oh." The ghost shadow swayed back and forth while bearing, in fact, in addition to eating and sleeping this day, in this narrow space, there was no opportunity to do more exercise, and the digestion speed was far less fast than outside, plus most of the food they ate was high-calorie food, so eating a meal could basically last a day, but when it was time to eat, they still didn't feel hungry, but they still had to eat some routinely.

"If we continue like this, we'll all be fat." Heavy Punch obviously feels like he's gained weight in the past few days.

"I don't eat it, you have an appetite, you eat." The worm was just going to make a cup of coffee to drink and didn't want to eat anything.

After a few people returned, the ghost had already prepared things, and the self-heating rations had already begun to steam.

"I'm not eating." Worm said.

"If I don't say it sooner, I'll get one less." The ghost said.

"It's yours." Worm sits cross-legged on the bed and drinks coffee.

"Alpha, how's the data transfer?" Heavy Punch asked as he ate with his head down.

"The data transmission is 57, and the current depth cannot be contacted by the outside world, and it needs to be raised to the communication depth next time before it can continue to transmit." Alpha said.

"Well, this data is important, and it must be passed on to the doctor." Heavy punch said.

"The underwater voiceprint data of different types of submarines have been stripped from their radar system, the type of radar wavelength, the detection method, the principle of operation, the operating system, ......" Alpha began to babble again.

"Okay, I know all of this, so I don't need to report it." "You just need to take advantage of the opportunity and send this data back as soon as possible, the doctor must be quite interested in this thing, and besides, continue to monitor their every move, we must know what they are doing, and what they report to the higher authorities and the orders they have given from above, understand?" ”

"Yes, I will keep an eye on it and report the situation at any time." Alpha said.
