There are only two classes of submarines in the Federal Navy.

    One is a "seal class" submarine with a maximum displacement of 2500 tons, and the other is a "sea lion class" submarine with a maximum displacement of 5500 tons.

    In most cases, submarines will accompany the aircraft carrier battle group, but sometimes they will go out alone to perform some special tasks, such as hunting sea monsters, exploring a certain area of the seabed, and so on.

    The submarine fleet now appearing in the Xinglan sea area includes 15 "seal class" submarines and 5 "sea lion class" submarines, and its mission target is the sea monster.

    "Ladies and gentlemen, the coordinates of the suspicious target found by the third satellite control center are located in a trench 8 kilometers ahead, with a depth of 4500 meters and a width of less than 500 meters. The terrain is very complex. Please be careful..."

    The commander of the underwater fleet, the water Olympian and rear admiral, Bromfield, said in a low voice on the communications channel.

    "I understand!"

    "Got it!"

    A sonorous and powerful response, immediately rang up.

    More than 4000 meters deep sea, is a dark and cold world, but also an unknown mysterious world, magic submarine has not been invented before, human footprints have never reached here, even the extraordinary water system is no exception.

    However, the birth of magic submarine changed everything.

    The submarine shell known by magic alloy is enough to withstand huge water pressure. At present, the largest deep diving depth of the human Federation has reached a record 12000 meters.

    The invisible magic wave from the submarine continuously sweeps the dark seabed and the surrounding boundless sea area, displaying all kinds of information in a large three-dimensional image with a diameter of 2 meters.

    This is a new type of black technology that combines underwater radar and hologram. It can directly display three-dimensional images, which is more conducive to observing the battlefield environment and commanding operations.

    At present, this new radar system is only equipped with the Navy, and the traditional crystal light screen is used in civil ships.

    Bromfield, sitting in the battle command room, scanned the three-dimensional images of the undersea mountains and many small blue triangles suspended above the mountains, without any expression on his face.

    The latter are scattered deep-sea fish, at this time they are swimming aimlessly.

    This deep sea, which is hard to penetrate by sunlight, can be called a barren underwater desert, unable to support a prosperous ecosystem, so there are almost no schools of fish.

    In addition, at the bottom of one of the trenches, a reddish ring is flashing.

    This is the target location of the tag.

    The submarine fleet made a full circle over the trench and found no suspicious targets.

    But that doesn''t mean the enemy doesn''t exist.

    "Under the major general''s crown, the shipboard large-scale disaster detector detected the smell of corruption at all positions in the target area, and the maximum index even reached more than 20 points."

    A solemn voice came from the communication channel.

    "This shows that the intelligence of the third satellite control center is completely correct. There are indeed sea monsters infected by" dissimilated energy "in this area, and there are not a few."

    "We speculate that this should be a servant army of the demons, hiding in the deep sea area in order to avoid the scanning of the disaster scanning satellite."

    "This time, phoenix nest space city has upgraded its satellites. The UHF magic waves they emit can penetrate up to 7.5km of rock strata or close to 10km of sea water. Only then can we find traces of alien sea monsters..."

    Bromfield frowned and asked:

    "the trench is only 4.5km deep. According to the calculation, the UHF magic wave should be able to penetrate at least 3km of rock after penetrating the sea So there is a super sea cave at the bottom of the trench, and dissimilated sea monsters hide in it

    "The only explanation is that the major general is crowned!"

    Blomfeld nodded and issued an order:

    "since there is a valet army hiding in the trench, the scale of the sea cave must not be much smaller Radar center, scan the bottom of the ocean for me! "

    "Yes

    The rear admiral was acutely aware that a strong wave burst from the front of the submarine and shot down to the undersea mountains.

    Then, a message came from the radar Center:

    "under the crown of major general, the magic terrain scanning radar has made a new discovery, and the information has been synchronized to the three-dimensional image The penetration depth of terrain radar to rock strata is limited, and the maximum penetration is only 2km, so we did not find the sea cave, only scanned the channel connecting the sea cave. "

    As soon as the voice fell, the three-dimensional image suddenly changed.

    At the position where the red circle is located, dozens of thin lines appear, pointing down. This is exactly what the magician called "passage".

    Anyone with an eye to see this scene must know that these channels are not formed naturally, because they are almost vertical in shape and neatly arranged in two rows.

    There is no doubt that it must be man-made.No, "weird" building.

    Bromfield gazed at the channel in the three-dimensional image and said faintly:

    "all attention, sea monsters may rush out of the channel at any time. Please be ready for battle!"

    "Yes

    The submarine group immediately began to move and set up a standard battle formation.

    Blomfeld took a deep breath and issued a command:

    "all seals, release the UAV and explore the channel."

    The water from the top of each miniature submarine suddenly spewed out to one meter from the top of each submarine.

    With the current technology level of the human Federation, there are no obstacles for equipment such as UAVs and unmanned submarines. However, the military does not attach much importance to unmanned machinery, only regards it as an auxiliary equipment, and rarely uses it for frontal operations.

    The reason is very simple - there is extraordinary power in this world. The power of the combination of the extraordinary and the rune magic weapon is far greater than that of the simple unmanned machine.

    For example, when a charismatic fighter drives a silver hawk, with the help of charismatic power, the fighter can make maneuvers that cannot be completed under normal circumstances.

    Another example is the dangerous "stall spin". If the UAV falls into the stall spin state, it can only crash, but those with extraordinary wind system can rely on the extraordinary power of the wind system to forcibly get rid of the stall spin.

    Everyone in the command module stares at the cursor representing the unmanned submarine in the three-dimensional image, watches them move towards the trench, and finally hovers hundreds of meters directly above the passage.

    "Enter the channel and turn on the ''condenser detector''!"

    "Yes

    The "cursor" starts to move again and enters the channel at the bottom of the trench. Each "cursor" selects a channel and drills into it.

    Next to the three-dimensional image, above a 1-meter-square holographic imaging device, the air suddenly rippled, and finally flashed around the unmanned submarine.

    Although the unmanned submarine has no light and is as dark as an abyss, in the hologram, the channel is very delicate, and the soldiers can clearly see the rough rock walls and the friction marks left on the surface.

    Blomfeld''s eyes flashed and asked:

    "what is the maximum display range of the ''condenser detector''

    "1.2km!"

    A magician replied quickly:

    "but the clarity of the image will be reduced by 60%, and the color of the image will be distorted."

    Bromfield cheered decisively:

    "make it the maximum!"
