The holographic images from the unmanned submarines are rippling again.

    After a breath, the ripples dissipated and a new image appeared.

    Although it looks a lot blurred, but the display range increased more than ten times, the diameter of the channel from about 2 meters, reduced to arm thickness.

    Of course, this is the size of the hologram, not the actual size.

    "According to the detection of magic wave, the channel diameter is more than 50 meters!"

    A magician looks at the light screen in front of him and calls out a data.

    Blomfeld''s face changed slightly:

    "so the" alienated sea monster "in the passage has a body diameter of only 40 meters at most Damn it, this is the level of upanism. I hope there won''t be too many upanists in it... "

    The largest submarine of the Federal Navy, the "sea lion class" submarine, is 145 meters in length and 40 meters in diameter.

    In other words, the size of an aoyi class sea monster is similar to that of a sea lion class submarine. Such a huge thing is absolutely not easy to deal with.

    The speed of the unmanned submarine is quite fast, more than 10 meters per second. Only two or three minutes later, the end of the hologram changes significantly, and the narrow channel suddenly becomes open.

    There was a slight commotion among the soldiers.

    "My God, there is a cave at the bottom of the trench..."

    "Looking at this posture, the size of the cave exceeds the detection limit of the" condensing light detector ", that is to say, at least 2 kilometers..."

    "It''s more than 2 kilometers. There are more than 40 passageways here. I feel that they should be connected to the same cave, so it''s definitely a super giant cave, with a width of at least 50 kilometers and a depth of more..."

    "My God, a 50 kilometer wide cave? How many sea monsters should there be, 2000 or 5000? "

    "There can''t be 5000 of them, can there?"

    While the soldiers were discussing in a low voice, Bromfield issued a command again:

    "connect all the detection data of the unmanned submarine to the grid for display!"

    "Yes

    Ripples cover the hologram and "Refresh" out a wider range of effects.

    The "grid connected display" in the words of rear admiral does not seem to be very powerful, but it represents a new generation of magic wave communication technology, which is called "distributed magic power communication network" in terminology.

    In short, every magic communication device may become a communication center. It is no longer the same as before. The center is the center and the terminal is the terminal. There is a clear distinction between the two sides, that is, the "fixed magic communication network".

    This design has a huge advantage, the command center is no longer fixed, it can be transferred to other equipment at any time.

    Even if the submarine where the commander is located is sunk by the enemy, other officers can take over command at any time, so that the whole army will not fall into chaos.

    Therefore, this modest change is of great significance. It can be said that it is absolutely a revolutionary progress.

    As a soldier guessed, it was a huge deep-sea cave with no boundary.

    This scene caused a burst of exclamation, and Bloomfield''s look became more serious.

    At this time, a rapid voice sounded in the communication channel:

    "under the crown of major general, the No.12 unmanned submarine detected the sea monster..."

    In fact, there is no need to prompt. The soldiers have noticed that a few red light spots suddenly flashed in the "lighted" cave area of the fastest unmanned submarine.

    The main detection object of the detection equipment loaded on the unmanned submarine is the netherworld, so the color of dissimilation energy is the most prominent red.

    And the stronger the dissimilation energy is, the redder the color is. The monsters of awakening level are generally light red, the monsters of extraordinary level are bright red, and the monsters above upanism level are dark red.

    At this time, all the red dots in the hologram are bright red, that is, the alien sea monster of extraordinary level.

    Bromfield yelled:

    "keep diving. I want to see how many sea monsters there are in the cave!"

    "I understand!"

    Sea monster also seems to notice that the unmanned submarine, red dot into the channel, fast approaching the submarine.

    For the Federal Navy, although the cost of unmanned submarines is not cheap, as many as 800 jinnals, it is just a kind of consumable. It doesn''t matter that all the 20 unmanned submarines are consumed.

    Bromfield also ordered:

    "speed the unmanned submarine to the maximum!"

    The moving speed of the hologram has accelerated sharply, the scope of the caves has become larger and larger, and the number of red spots has changed from 3 or 4 to dozens.

    The sound of unmanned submarines naturally makes more alienated sea monsters. More than half of the unmanned submarines are targeted by sea monsters.

    After a few breaths, the image of the unmanned submarine in the front suddenly trembles and becomes extremely blurred."The 12th is under attack!"

    As soon as the voice fell, part of the hologram disappeared.

    It''s clear that the No. 12 unmanned submarine was destroyed, or the internal detection equipment was damaged.

    This is not surprising. The size of the unmanned submarine is too small, and its protection ability is almost zero. Facing the sea monsters who master the water system ability, they have no resistance ability at all. As long as the other side throws a torrent, it will be enough to damage the unmanned submarine.

    This is just the beginning. In the next few seconds, the unmanned submarines were destroyed one after another, and the holographic image was also incomplete by more than 80%.

    In the end, only three unmanned submarines safely passed through the channel more than 4 kilometers long and entered an extremely open bottomless abyss. What appeared in front of people were dense red spots, a few of which were light red, and the rest were bright red.

    The three unmanned submarines did not "live" for a long time. They only advanced less than 300 meters, then they were approached by sea monsters, completely lost contact, and the hologram disappeared.

    The soldiers in the command room were quiet for a moment, and suddenly there was a loud discussion.

    "It''s incredible that the unmanned submarine has detected at least 500 sea monsters, which may be just a tiny part of the cave..."

    "Just now someone said that there might be 5000 sea monsters. Now it seems that there are more than 50000 sea monsters. This is a sea monster Cave..."

    "The density of sea monsters is very abnormal. Why do most sea monsters keep motionless all the time, even when unmanned submarines approach, they don''t react?"

    "I have a guess that they may be in a dormant state to save energy consumption. After all, this is an abyss nearly 10000 meters deep, and they are extremely short of food..."

    "Damned netherworld, there are so many powerful sea monsters hiding in the deep sea. What do they want to do?"

    "What else can I do? This sea area is only 860 kilometers away from Xinghai mainland, and almost 1300 kilometers away from Haichao collar. These tens of thousands of sea monsters either attack Xinghai mainland or Haichao collar. There is no third possibility... "

    Bromfield looked around and yelled:

    "be quiet!"

    Then he gave a series of instructions:

    "Lieutenant Beaufort, immediately inform the Navy headquarters of the situation. There are too many sea monsters in the deep-sea caves. 20 submarines can''t handle them. We need more submarine support..."

    "Captain servis, go to the federal prime minister''s office and ask them to temporarily designate the sea area within 200 kilometers as a restricted area for navigation, and evacuate all civilian ships in the nearby sea area as soon as possible..."

    "Finally, all of you are ready to fight and kill these sea monsters!"

    "Yes

    The soldiers responded in unison.

    No one expected that the first shot of this all-out war would be fired from the bottom of the sea.
