Pacific Ocean, Dragon Delta.

This notorious sea area has been shrouded in mystery due to the frequent incidents of planes or ships disappearing or sinking, and a considerable number of victims did not even send out a call for help, so it is called the Bermuda Triangle of the East.

There are countless rumors about the sea among fishermen and ocean-going sailors, most of which are so bizarre that they even involve aliens or supernatural forces, and have never been seen in mainstream science.

The weather in the Dragon Delta is as bad as ever, the sea is rough, the sky is gray, and the dazzling waves are large enough to throw a superfreighter into the air, and the keel may have broken when it falls.

However, no matter how bad the conditions on the surface of the sea are, no matter how bad the weather is, it will not be able to affect the two hundred meters below the surface, and at this depth, the currents dominate.

Even on a sunny day, the sun doesn't shine two hundred meters below the surface of the sea, and it's basically pitch black, except for some self-glowing fish, shrimp, and plankton that flicker with a faint cold light, attracting prey that throws themselves into the net.

A new guest arrives today, silently intruding, as large as a giant whale, and seemingly oblivious to the horrors of the place.

This is an attack nuclear submarine of unknown nationality, and the two nuclear reactors provide it with enough power to cross the Pacific Ocean in one breath, and if necessary, it can remain on the surface for two or three months without surfacing in a state of combat readiness cruise, quietly lurking under the surface of the sea, playing a game of cat and mouse with potential enemy submarines, and the biggest task is to track the enemy's strategic nuclear submarines, sink the target when receiving combat orders, and strive to keep itself from being sunk by the enemy's attack nuclear submarines.

However, the submarine on the mission today received a telegram ordering it to abandon the target it had been tracking for several weeks and temporarily transfer to another mission, the details of which are top secret and can only be read by the captain, not even the first mate.

Most of the crew members are confused, you must know that it is rare to find the enemy's strategic nuclear submarine in the vast sea, they have been tracking it for so long, and it is not a pity to give up like this?

But an order is an order, and no matter what you think in your heart, you must carry out the order without compromise.

The captain had a gloomy face since receiving the order, and instructed the navigator to sail the submarine to this area.

The crew dismisses superstitious rumors, but they also do not understand what is the value of this sea area with an average depth of more than two thousand meters, because strategic nuclear submarines often need to "sit" on the bottom of the sea and wait for the ultimate order that is enough to push all mankind into the abyss, and this sea area is too deep to float if it really "sits", so it is impossible for strategic nuclear submarines to cruise in this sea area.

"What did you find?"

In the command room, the captain of the boat, with his sideburns and white uniform, asked the listener.

"Uh...... There is a merchant ship in the direction of 2-7-6, about 1000 meters away, battling the storm. The listener with headphones stared at the echo diagram on the screen in front of him that was too obscure for the average person.

"What else?" asked the captain again.

"The storm noise on the sea was too loud and no other ships were found...... Sir, what exactly are we looking for?" asked the listener boldly, he was also qualified to ask, otherwise wouldn't he be looking for anger?

The captain groaned slightly, and said, "The anomalous area of the magnetic field, and all the anomalous existence around the anomalous area of the magnetic field - I mean something that moves. ”

“......”

The listeners and sonarists looked at each other, and the captain's answer seemed to be no different from not answering.

"Anyway, if you hear a moving object that doesn't match the known noise signatures in the database, whether you suspect a submarine or a whale, report it to me immediately. The captain said.

"Yes, sir!"

The captain's eyes were glued to the chart on the screen, and the submarine had now sailed to an area very close to the coordinates in the command, and the further it went, the more dangerous it became.

"A third is moving at full speed. He ordered.

The helmsman reduced the speed of the submarine, which had previously been rushed almost at full speed.

"All into combat positions. The captain ordered again.

The first mate conveyed the instructions to the entire submarine through the walkie-talkie, and all the crew members got busy, put down all their idle affairs, and automatically ran to their own posts to standby, and all wore anti-flash masks and gloves to deal with the situation of the submarine being shot and fire during the battle.

"Turn on the bow and actively detect sonar. The captain said.

The sonar operator was stunned, thinking that he had misheard, because entering the combat position and turning on the active sonar were mutually exclusive commands, and when entering the combat state, it was necessary to avoid exposing one's position as much as possible, but hitting the active sonar was equivalent to loudly announcing its position to all potential enemy submarines in the forward cone area, which was simply suicidal.

"Didn't you hear that?" the captain glared at the sonar officer disapprovingly.

The sonar officer turned to the first mate with his gaze.

"Sir......" the first mate tried to admonish.

"Carry out the order, I am responsible for everything! The target of this operation is not an enemy submarine, there should be no enemy submarine nearby, and even if there is, it probably won't trouble us. The captain accentuated.

"Yes......" the sonar man turned on the active sonar with a confused expression.

The others also listened stupidly, if they don't fight the enemy submarine in the sea, is it fighting with the Dragon King?

Active detection sonar emits a powerful sound wave in front of it, which can be transmitted at a very long distance in the seawater, and the sound wave is reflected back when it encounters an obstacle and appears on the display as an echo pattern, which is much farther than simply listening to the sound of water.

"Anomaly found ahead!" the sonar man concentrated, "0-1-3, about ten kilometers away!"

"What is it?" the captain leaned over.

"I don't know...... The shape is irregular and in a suspended state...... It may be a salt anomaly site. The sonar man tried to make out it, but the echo was shaped like the chaotic presence in front of him as a mass of irregular water.

The salt content in the seawater is not exactly the same, even in the same sea area, the salt content of the seawater at different depths is not the same, and even occasionally there will be a rare stratification phenomenon, the upper layer of seawater has low salinity, and the lower layer has high salinity.

If it was a normal training, the captain would probably pat the sonar officer on the shoulder to show his approval, because it was indeed a place of salt anomaly, but the reason was not what the sonar man thought, the salt anomaly was the result, not the cause, because the sea water there was mixed with the sea water from another world, and the salinity of the sea water in the two worlds could not be exactly the same, and even the salinity of the sea water in different parts of the earth was different.

"Stop moving, levitate in place, and dispatch the underwater robot. The captain ordered.

The huge submarine slowly stopped, and a thing similar in size and shape to a torpedo was launched, with a fiber optic wire attached to it, which was an underwater robot, equivalent to a miniature doppelganger of the submarine, performing close reconnaissance or other dangerous tasks for the submarine, and the operator was remotely controlled by optical fiber, so the robot would not be disturbed by the outside world and lose control.

The torpedo-like robot turned on its front searchlight, and the snowy beam illuminated the dark waters, and the frightened fish scattered and fled, but some phototaxis sea creatures approached curiously.

The camera transmits the captured footage back to the submarine via fiber optics and displays it on the screen.

Two hundred meters underwater is far from the deep sea, and the occasional surprise of marine life in front of the camera is relatively common, so there is nothing to make a fuss about.

As the robot quietly approached the salt anomaly, the sonar crew suddenly exclaimed, "New target found!"

"Where?" asked the captain.

"It's ...... The location of the salt anomaly, but why didn't it be found before...... sonar man stumbled, he couldn't understand the echo map at all, it seemed that something was from the location of the salt anomaly...... Squeeze it out, like a pregnant woman giving birth, but how is this possible?

"New targets are moving...... Very fast, 0-4-0 in azimuth, 35 knots!" sonar officer reported.

The listener also held on to the headphones as if he was suspicious, "It's not a sperm whale...... Nor is it a gray whale...... Can't hear the propellers...... Ahh

The listener screamed, took off the headphones and threw them away, because at that moment, there was some kind of extremely sharp cry, unlike all the sea creatures he had ever heard, almost like ...... Banshees from Hell.

"Torpedo tubes No. 1 and No. 2 are flooded!" the captain ordered.

Although it was not known what the target was, the torpedo operator faithfully carried out the order and prepared the two torpedo tubes in the bow of the boat for firing.

"The robot is going 0-4-0, let me see what the hell this guy is......" the captain clenched his fists.

The robot changed direction.

"2 km from the target......"

"1 km from the target......"

"400 meters away from the target, contact is expected in 14 seconds. ”

"150 meters away from the target, expected to contact ...... in 5 seconds"

Everyone in the command room stared at the screen with wide eyes, even though the robot had its searchlights on and was disturbed by the storm on the sea, the sea water was relatively muddy, and the visibility was not high.

Suddenly, something appeared in the range of the searchlight, but due to the fact that it was walking in the opposite direction of the underwater robot and its relative speed, the camera only captured a very brief footage.

Such a picture made everyone in the command room stunned, even if the enemy nuclear submarine suddenly turned into a platypus, they would not be shocked like this.

"That's ...... What monster?"

The same question popped up on everyone's mind.

At that moment, they saw a ...... The long, stout animal flashed from the edge of the searchlight, it seemed that it had no limbs, the muscles of the trunk were unusually strong, and there were four organs similar to eyes on the left and right sides of the torso, but it seemed that there were no eyes on the head, but a huge mouth that scared everyone present, the square mouth was densely covered with sharp teeth, and in the middle was a bottomless throat, biting towards the searchlight, and in a flash, the robot lost its signal.

"The target is accelerating! Direction 0-8-5!" the sonar officer reported.

The captain scolded secretly, this guy wants to escape?

No, it didn't run away, it probably felt that the robot was not to its taste, and accelerated towards a tuna that appeared in the wrong place at the wrong time, and without giving the tuna any time to react, it bit it into two pieces, and the tuna, which weighed hundreds of kilograms, was eaten only by the head and tail in a few bites.

"Torpedoes No. 1 and No. 2 are fired!, direction 0-8-5!" the captain ordered, "The torpedo is set to be manually detonated." ”

Two heavy torpedoes burst out of the launch tubes, also connected to the interference-free fiber optic wires, because the sonar signature and noise characteristics of the target were not recorded, the torpedo could not automatically match and track the target, and could only be manually controlled by the operator.

The monster seemed to sense that something was following it, and the eight organs on its side that looked like eyes could see a range of 180 degrees in front and back, adding up to 360 degrees, and each eye was large, providing it with excellent low-light vision, and maybe it could also superimpose and synthesize the visual images seen by each of the four eyes into noise reduction, even at a depth of two hundred meters below where it could not reach its fingers.

It spun sharply in an attempt to shake off its tracker, its physical agility was far greater than that of a torpedo, but the torpedo was not an animal, and until it ran out of fuel or escaped from range, it would always bite behind it, and even if it was temporarily thrown off, it would still find its target again under the guidance of the operator.

Seeing that it was about to be chased by a torpedo, it seemed to sense the danger, and its body suddenly swelled several times, as if it opened its mouth and poured a belly of seawater, pouring itself into a rugby ball, and then squeezing the sea water out of the back of its body.

At the same time, the No. 1 torpedo exploded, and the seawater at the explosion site was first vaporized under high temperature and pressure, and then a large number of bubbles were compressed centripetally under the water pressure, and the surrounding sea water was violently turbulent, but the monster obtained a speed explosion through a strange movement, and escaped the scope of the explosion at the last moment.

However, it could not dodge the fifteenth of the first day, and the No. 2 torpedo pierced through the aftermath of the explosion, and now it could not dodge it anymore, and was solidly blasted, and with a muffled sound that could be heard even in the submarine, the monster was finally left with no bones - it was an exaggeration to say that, in fact, it had a tail that remained intact and slowly sank to the bottom of the sea, and if the scavengers on the bottom of the sea did not like the taste of this tail, there might be a chance that it would be washed up on the beach one day.

Although the monster was destroyed, the crew was still immersed in the scene for a long time, and the robot was destroyed, but at least the footage was preserved.

"Delete the video you just made and don't keep a backup. The captain ordered.

"Sir......

"Carry out the order!" the captain pursed his lips, his face sinking as if he was about to drip water, and looked at the salt anomaly on the echo map, "You think the battle is over? No, the battle has just begun!"
