Japanese piranha crabs, also known as tall crabs, have fully stretched out limbs, can reach two or three meters in length, and stand up to about one meter tall, .com not like Alaskan king crabs, although they are large, they are slow, docile, and easy to catch.

The reason why tall crabs are called man-eating crabs is because there was a phenomenon of man-eating crabs actively attacking humans in the Wa country, so it was called so. Perhaps the divers saw the man-eating crab and mistook it for an Alaskan crab, which caused the tragedy.

"Is this just an incident?" Chen Si asked Nelson, he thought for a while and said: "The anti-compression suits on these divers are of good quality, plus they are fully enclosed, if they are attacked by man-eating crabs, they should not die, and can they still monitor their breath of life?" "Chen Si is very familiar with the skills of the Chinese people.

"I can't find it at all." With a pained look on his face, Nelson continued: "It's not just one incident, it's the same thing, a lot has happened, look at this. Nelson played another video. In the video, there are also two crew members, they are diving underwater, and then the camera goes black and nothing can be seen. Except for the first video, everyone else basically disappeared like this, and a total of thirty-five divers were sent into the water, but only twenty-seven came up alive. Eight divers just disappeared underwater. Seeing that the situation was not good, Nelson immediately issued an emergency notice calling all divers to return. Otherwise, the number of losses for these divers could be even greater.

"What the hell is going on, can you give me an analysis?" Nelson wiped the beads of sweat from his forehead and gasped. Having lost eight soldiers at once, he didn't know how to write a report and hand it in.

"There's more than one aggressive marine creature here." Gu Fengchun took the lead in saying. Nelson was immediately attracted by his remarks and said, "Mr. Koo, please continue. ”

"Mark me the location of these divers who had an accident." When Gu Fengchun was watching these videos just now, he obviously found some details that ordinary people would not pay attention to. This is an essential professional function as an archaeologist,

"Okay." Nelson immediately motioned for his men to make a mark on the monitor. According to Gu Fengchun's request, the person who had the accident was divided into two different colors.

"Look." Gu Fengchun pointed to the distribution map and said: "This distribution map is centered on the warship, extending into the distance in a radiating way, the nearest is three nautical miles, and the farthest is seven nautical miles, please look at the first accident location, they had an accident in the direction of four o'clock." Gu Fengchun paused and said, "The rest are concentrated in the direction of eight to eleven o'clock. It also shows that only these two places are most dangerous in this sea area. ”

Chen Si squinted his smile and listened carefully to Gu Fengchun's analysis. But in his heart, he wondered how Nelson would lose more people. I didn't want Gu Fengchun to make an analysis, so that Nelson would have a headache for a while, and it would be better to die a little more. He also knew that Gu Fengchun's heart was not as black as him, and such a thing could not be done.

Nelson nodded repeatedly, this is the basic method of elimination, as a high-quality officer, he will also do, but when the situation is dangerous, he only cares about the number of casualties, and forgets what he should do more.

"It can be judged that the dangerous existence in this place is the tall crab, which is the so-called man-eating crab." Gu Fengchun's hand drew a circle around the four points, and immediately the programmer marked the dangerous area in red.

"But here, we still need to make further judgments," Gu Fengchun gestured in the direction of eight to eleven o'clock, and then said, "Give me a list of the chronological order of the accident in these areas and the distance between them." ”

Nelson was very appreciative in his heart, this ancient Fengchun mind is very meticulous! After the data came out, Gu Fengchun's brows were furrowed.

Needless to say, everyone saw the clues. The time of the accident ranged from 30 seconds to a minute, and the distance between each of them was not far, the farthest was only half a nautical mile, and the nearest was less than 300 meters.

What is strange is that the disappearance of these people turned out to be from far to near, starting from eleven o'clock counterclockwise, and gradually coming in the direction of eight o'clock. The distance is also getting closer to the destroyer. "What's going on?" Nelson shook his head, puzzled.

"Have you sent out any submarines back?" Chen Si asked suddenly.

"Not yet." Nelson replied, and after speaking, he motioned to the programmer on the side to turn on the monitoring of the submarine. He looked at the data on the side and said: "The two small boats are very safe at the moment, one is in the direction of six o'clock, and the other is in the direction of two o'clock, where the sea is deep, they have dived about 400 meters or so, and everything is normal." ”

Chen Si and Gu Fengchun were excited at the same time, and said loudly: "Let the submarine in the direction of six o'clock float immediately, quickly!" ”

Nelson was puzzled when he saw the sudden change in the faces of the two. Gu Fengchun's voice was out of concern for human life, but Chen Si felt sorry for the submarine. This destroyer is equipped with a total of two such small submarines, and it would be a pity to lose one.

Chen Si and Gu Fengchun had already roughly judged what was attacking this diver.

It's a big octopus. In Northern Europe, this thing is also called the Norwegian sea monster. It's not easy to make such a judgment until you've seen the real thing. However, for Gu Fengchun and Chen Si, it will not be too difficult. From the video, it can be seen that the divers have approached the bottom of the sea, and from the recorded seabed, they have found a trace that is not easy to find: drag marks on the sand of the seabed. It's as if something is pressing on it and being dragged through. Gu Fengchun initially thought of the Leviathan, who had chased them abandoning the ship and fleeing not long ago, but he quickly dismissed the idea. Because the Leviathan is so big, if it appears, the destroyer's sonar must have sensed it.

Later, he found that there would be a burst of ink black before the picture disappeared in the video, and ordinary people might think that this was the camera blocked or broken, but Gu Fengchun judged that this was the black ink sprayed by the big octopus, interfering with the prey's line of sight, and then captured.

The only thing the two couldn't be sure of was how big the big octopus would be.

The size of the large octopus has always been a concern of marine biologists, and the longest large octopus found in the carcass of the large octopus is 18 meters long with its body and antennae connected. And those large octopuses that have not been found in the deep sea can only imagine how big they can be. Some sailors have seen that in the vast sea, a big octopus is hunting sperm whales. The sperm whale is huge, but the giant octopus can be easily hunted, so you can imagine how large this giant octopus is.

Nelson listened to the words of the two, immediately turned on the communicator, and said in a loud and urgent voice in English: "The submarine is up, return immediately!" "I kept repeating it several times.

And just as he gave this order, the detection display of the submarine at six o'clock disappeared from the screen.

"W-what's going on?" Nelson's voice trembled.

"I guess I've met a big squid." Gu Fengchun frowned and said his conclusion.

"Oh, damn it!" Nelson's forehead was bruised, and he said loudly: "Stupid pigs, turn on the deep-sea radar and all detection systems, get your torpedo ready, I'm going to kill that big squid raised by a son of a bitch." "That little submarine is worth a lot of money, about five million dollars in fraud, which is more expensive than the Apache, and there are two senior submarine pilots in it, these are the elite of the army! died like this, and if I don't avenge them, I'm really sorry for Uncle Sam.

The corners of Chen Si's mouth rose slightly, Gu Fengchun was very puzzled when he saw this evil smile, and asked Chen Si, "What are you thinking?" ”

Chen Si put up his right index finger, put it to his lips, smiled mysteriously, and said, "Don't say it, don't say it!" ”

"Rub!" Looking at Chen Si's villain-like appearance, Gu Fengchun immediately scolded.

On a small Russian warship dozens of nautical miles away, Qin Chuan's ears were hot, and he let out a sneeze "...... gas".

"Who's thinking about me?" Qin Chuan muttered. Jin Ying, who was next to him, frowned, held a report card in his hand, and said: "Within three hours, nineteen of our team members were sacrificed, twelve of them were Russian sailors, most of them died in shark kisses, and three died in sea snakes. Also, it seems that some crew members have seen the traces of the merman, and I don't know if it's a hallucination......"

Qin Chuan listened to the casualty data, his brows did not blink, and when he heard the word merman, he immediately became interested, and immediately said: "Where did you find the merman, mark that location, whether it is true or not, and list the area within a radius of three nautical miles over there as a key reconnaissance target." ”

Kim Young nodded and quickly took notes on his tablet.

"Chen Si, it seems that I am going to be one step ahead of you. In this race against time, it's clear that you've lost. The corners of Qin Chuan's mouth also rose slightly, and he smiled reservedly.

"Hah...... Ball ......" Chen Si's nose itched, and he let out an earth-shattering sneeze. He wiped his nose embarrassedly, glanced at Gu Fengchun, and said: "It's good to scold people in your mouth, but you still scold in your heart, you are still not human!" ”

Gu Fengchun's face twitched and shrugged his shoulders. Speechless.

The target of the big octopus was quickly determined. This body size will not be less than thirty meters. If you can catch it, it will definitely cause a sensation. But Nelson, who was furious, didn't think much about it, and he immediately shouted: "Torpedo aim, shoot!" ”

Gu Fengchun was taken aback and was about to speak, but was stopped by Chen Si with his eyesight.
