Chapter 529 Arriving at the Foot of the Mountain
The process of entering the water is of course very simple. The side we are on is still quite far away from the villa, so the distribution of people is not particularly dense, and we can easily dive into the water.
Although we didn’t bring Aina with us this time, it’s not that others on our side don’t know how to use sonar, they just don’t have Aina to play around with.
Although this lake is not small, it is not particularly big either, so when we entered the water, we discovered several underwater targets as soon as we deployed the sonar.
"Underwater target detected." A large number of red marks instantly appeared in our mental network. These are not fish, because there are no such big fish in this lake.
It can be seen from the information fed back by the sonar that the targets in the lake are roughly divided into three types. The first type has a particularly large signal, and is initially judged to be a small submarine. Yes, that's right, a small submarine. Although I don't know when these submarines were obtained.
The second feedback signal is slightly smaller than that of the submarine, and it is initially judged to be a diving robot. The third signal is smaller and should be from Frogman.
The feedback signals of the three targets are completely different, so we can easily analyze which targets are which, but the number of these targets is very large, which looks a bit scary.
"Master, we cannot use the mirage system in the water. If the other party uses active sonar, we will definitely not be able to hide ourselves." Xiaochun's words were not to remind me, but to ask me if I needed to return to the shore. After all, we were here There is no way to hide yourself in the water. Although the power armor on our body is very technologically advanced and equipped with a variety of black technologies, the only function this thing does not have is the sonar shielding function.
In fact, the reason why the sonar shielding function is not installed is not because we do not have similar technology, but because we never thought of installing such a thing in the first place. Everyone knows that sonar is actually a technology that relies on the reflection of sound by objects for positioning. The size of this reflected sound wave is mainly related to the volume and material of the target itself. certainly. Passive sonar is another technology, which is actually very different from active sonar.
Generally speaking, submarines rarely activate active sonar underwater. This is mainly because the sound wave generator of active sonar is like a super big light bulb to passive sonar, which can be detected from a long distance away. Although active sonar has a better ability to search for targets than passive sonar, once your active sonar is turned on, it means that you have exposed your position first. This is also the reason why there have been accidents in which submarines from the two countries collided underwater. Because no one dares to turn on active sonar, and military submarines have relatively good silent technology, neither submarine turns on active sonar, just like a person holding his breath and moving lightly in a dark room. No one made a sound, the room was too dark and nothing could be seen, so it was not surprising that they bumped into each other.
Precisely because people generally don’t use active sonar. And we are dragons, not submarines. Our propulsion sound in the water is much quieter than that of submarines, and it is impossible to be detected by passive sonar. Therefore, our demand for sound wave absorbing materials is not strong. Say it again. Even if the other party turns on active sonar. We are so big, and there are many fish in the sea that are bigger than us, so the sound wave signal we reflect is definitely not very strong, and it is difficult for sonar operators to distinguish us from dolphins and the like. This further reduces our need for sonar camouflage. Besides, our armor is just a special coating without sonar absorption. This is not to say that there are no such designs at all. In fact, the sound wave reflection of the shell material of our power armor itself is very low. In the ocean, there will be great interference due to waves, which further reduces the possibility of us being discovered by active sonar. This determines that we almost don’t need to worry about sonar issues in the water. Because it is difficult to find itself.
However, the environment here is different.
This is a lake. Although it is not a backwater lake, it is just a lake after all. How much background noise do you think a lake can generate?
Just because the lake is so quiet, sonar facilities will work very well here, especially passive sonar. After all, active sonar also has to consider underwater echo issues, but passive sonar doesn’t have to worry about these at all. Although our underwater sound is not loud, it can be completely covered up by the background sound of the ocean in the sea, but it cannot be done in the lake.
Originally, we thought that the other party would prepare at most a few frogmen underwater and a few speedboats on the surface. We did not expect that the other party would even prepare submarines and underwater robots. This configuration is obviously a bit beyond expectations.
What can I say in this situation?
"Damn it, I didn't bring any weapons in the water. It doesn't look so easy." Amynis said.
I thought for a moment and said in the mental network: "We will move forward as usual. Since we can't hide it, let's push it forward."
"Really?" Jingjing asked in surprise.
I confirmed again: "Yes, push flat."
"I like this decision." Lingling said excitedly.
"Are you going to go directly like that?" Ling asked in the spiritual network with some uncertainty.
"Of course not. For flat pushing, we still need some skills. We will give full play to our strengths in a while."
With the thoughts I conveyed in the spiritual network, it took everyone a few seconds to fully understand my arrangement, and then began to move forward.
In fact, we were spotted immediately after we entered the water. After all, the other party's passive sonar can clearly hear the sound of any object entering the water. The lake is so big, so it would be weird if the other party couldn't hear it. However, just as they were gradually approaching us based on the signal, a harsh explosion suddenly came from the water, and then all the sonar equipment was destroyed in an instant.
"Damn it!" A sonar operator sitting on a speedboat grinned and cursed while desperately picking his ears. The earphones he had on his head suddenly emitted a high-pitched whistling sound, which was so explosive that his ears could hardly hear the sound now. He couldn't hear anything unless others shouted loudly.
"What's going on?" When he discovered that the sonar operator had actually taken off his earphones, of course the commander on the ship had to ask about the situation.
Although the sonar operator saw the boss asking questions, he couldn't hear it at all. He didn't hear clearly until the other party repeated it loudly three times. Then he replied: "I don't know. The other party used some method we don't know to create high-intensity noise underwater. Now the sonar system is completely useless."
"Hardware damaged?" the commander asked.
The sonar operator who had regained some of his hearing shook his head and said: "No, the sonar device has overload protection and is not that prone to problems. It's just because the noise is always there. So as long as the noise does not disappear, our sonar is useless. .”
"Damn it, they took advantage of me again."
In fact, if the commander knew what caused all their equipment to malfunction, he would probably be even more furious, because what caused all their sonar to become useless was not some complicated thing, but a lump of ice. Yes, it's ice cubes, ice cubes condensed from the lake water here. Of course, this ice cube is not a simple lump of ice. It is actually a very standard resonator, and it is a resonator specially suitable for underwater use. Its principle is similar to the wind whistle mounted on the wingtips of a dive bomber, but this one uses water flow instead of airflow to produce sound. Compared with the wind whistle, this water whistle is louder. And the frequency is wider, and the pitch of the sound can be changed simply by changing the speed of water flowing through the whistle.
This whistle was made by Shuangxue using her temperature control ability to freeze the lake water, and the user is Yeyue, because she is the fastest underwater among us. After all, her tail is really a good thing, very suitable for moving in the water.
Ye Yue held two water whistles in each hand underwater and walked through the water at high speed. And this noise makes all surrounding sonar devices useless. However, although the other party's sonar has lost its function, we are not affected in any way because we do not rely on sonar to determine the target at all. Previous sonar detection was nothing more than wide-area reconnaissance. Now that the target has been determined, we changed it to electromagnetic induction ability.
Submarines and underwater robots must carry a large amount of electronic and mechanical equipment anyway, and it is impossible to completely shield the electromagnetic signals emitted by these things. In such a large-scale scene in the ocean, it is indeed impossible to find a submarine relying on this leaked electromagnetic wave, but this is a lake, and its area is only that big. Although the opponent's submarines are all single-person submarines, in such a large place, it is too easy for us to determine the opponent's electromagnetic signal. Even to us, the signal strength of the other party is almost the same as that of fireflies in the dark night. Although the brightness of the fireflies themselves is very low, they are still so conspicuous in the dark night that it is difficult not to notice them.
As for those frogmen... To be honest, these guys' signals are super strong. Their brainwaves are exactly like a transmitter. We can clearly receive the brainwave signals of these people in the water. Not only their location, but also their emotions can be accurately sensed.
Relying on this asymmetric information collection ability, we easily got close to the fastest submarines, and then put a piece of soft glue with the word "Plastic Bomb" written on it toward the submarine's observation window in the eyes of the other party's surprised eyes. Ignore the previous post.
What we put on is just a piece of soft glue, but if it were actual combat, this would be a real plastic bomb. And we will not stick it on the observation window, but directly on the hull. Since we can stick this thing on the observation window silently, other locations are naturally easier.
The people inside the submarine knew they were killed when they saw the "bomb", and then followed the rules and pressed a temporary button. There was a loud bang immediately outside the submarine. Of course, this came from the loudspeaker, which was to tell others that he was "killed".
It's night now, nothing can be seen on the ground, and it goes without saying how dark it can be underwater. The sonar was disabled, and these people became completely deaf and blind. We easily approached and quickly lost all the ships and submarines. As for the underwater robots... it's even worse, because we persuaded them to surrender.
The dragons are all experts in electronic warfare, because our brains have some characteristics of electronic computers. Although our electronic brains are actually quantum computers, they are essentially compatible with electronic devices. In addition, our electromagnetic control can physically cross certain things at the software level, so it is difficult for computers to have any resistance in front of us. The unfortunate thing about these underwater robots is that they are automatic robots. If they were wire-controlled models, the most we could do was paralyze them, but now they have completely rebelled.
Because the robots rebelled, the frogman army was also wiped out. After that, we were at the lake and started shooting directly from the water to the shore. In an instant, bullets flew everywhere, and then the defensive troops on the shore were completely wiped out.
No one thought that we could directly attack people on the shore underwater. Common sense is that if we want to attack people on the shore, we should at least take the risk. But we just completed this process underwater, so the people on the shore There is absolutely no way to effectively fight back. Because we are underwater, the other party cannot determine our exact position at all, and the bullet will deflect to a certain extent when it enters the water. If the inclination angle is not large enough, it will even turn into a floating bomb. After entering the water, the bullet will bounce again and will not enter the water at all.
Originally, our defense was immune to most weapons. Now that we have water to help block bullets, and the enemy cannot find our exact location, our firepower is completely random. It is really impossible to create any deterrent under such circumstances, so the result is It was our side that killed all the opponents without even wiping bullets. After all, our electronic brain itself is pre-installed with ballistic calculation software, so even when shooting underwater, we still maintain a hit rate of more than 90%.
When we came ashore, looking at those miserable and colorful "corpses", we knew how much resentment these people had, because their brain waves were about to become substantial.
"Xiao Chun, give me another scan map." Ignoring the "corpses" around me, I gave the order directly in the psychic network.
"Do you want me to go up and take a look?" Xiaochun pointed to the sky.
"No need." I waved my hand and said, "Ifrit, throw in two reconnaissance planes."
Everett had just come out of the water, with water still dripping down his body. Hearing my order, he immediately bent over slightly, and the two slopes on both sides of his back suddenly bounced three times in succession. A round pancake-like gadget. At first glance, this thing looks like a flying saucer in an alien movie, but its surface is very smooth, without any protrusions, and its diameter is only twenty centimeters. The edge of this small flying saucer is a circle of blue cold light lines. It doesn't look very bright, but it is very beautiful.
This thing makes no sound at all when it flies, is very fast, and is extremely flexible. After being released, it flashed for a few times and disappeared completely, but the surrounding terrain map in our spiritual network suddenly updated on a large scale. The previous electromagnetic scan only received black and white maps, but now it is a full-color scan, and a large number of red marks are brushed out in the map area ahead. These are targets discovered by micro-reconnaissance aircraft, and the number is still rising rapidly.
"Damn, there are so many people!" (To be continued ~^~)
