Chapter 3306

Of course, the process of entering the water is very simple. Our side is still quite far away from the villa, so the personnel distribution is not particularly dense, so we can easily dive into the water.

Although we didn't take ADINA with us this time, it's not that other people don't know how to use sonar. It's just that ADINA doesn't play.

Although the lake is not small, it is not particularly large, so when we entered the underwater, the sonar just launched and found several underwater targets.

"Underwater target detected." In our mind network, a large area of red marks were painted instantly. These are not fish, because there are not so big fish in this lake.

From the information from sonar feedback, we can see that these targets in the lake can be divided into three types. The first one is a small submarine with a very large signal. Yes, that's right. It's a small submarine. Although I don't know when these submarines got here.

The second kind of feedback signal is slightly smaller than that of the submarine, which is preliminarily judged as a submersible robot. The third signal is smaller and should be frogman.

The feedback signals of the three targets are completely different, so we can easily analyze which targets are what, but the number of these targets is very large, which seems to be frightening.

"Master, we can't use the mirage system in the water. If the other party uses active sonar, we can't hide ourselves." Xiaochun's words are not to remind me, but to ask if I need to go back to the shore. After all, we can't hide ourselves in the water. Although our power armor is very advanced in technology and equipped with a variety of black technologies, its only function is sonar shielding.

In fact, we didn't expect to install this kind of sonar technology. As we all know, sonar is actually a kind of technology that depends on the object's reflection of sound. The size of the reflected sound wave is mainly related to the volume and material of the target itself. Of course, passive sonar is another technology, which is quite different from active sonar.

Generally speaking, submarines rarely start active sonar underwater. This is mainly because the acoustic generator of active sonar is a super light bulb for passive sonar, which can be found from a long distance. Although the ability of active sonar to search targets is better 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 submarines of the two countries collided underwater before, because everyone dare not turn on active sonar, and the mute technology of military submarines is relatively good. Therefore, both submarines do not turn on active sonar. It is just like a person holding his breath and stepping lightly in the dark room and moving carefully. Everyone doesn't make any sound. The room is too dark and can't see things It's no surprise to bump into each other.

Because we are dragon people, not submarines, our propulsion sound in the water is much quieter than that of submarines, and it is impossible for passive sonar to detect them. Therefore, we do not have a strong demand for sound absorption materials. What's more, even if it's an active sonar. We are so big. There are many fish in the sea that are bigger than us. Therefore, the acoustic signal reflected by us will not be much stronger. It is difficult for sonar personnel to distinguish us from dolphins and other things, which further reduces the need for sonar camouflage. What's more, our armor only has no special coating for sonar absorption, which doesn't mean there is no such design at all. In fact, the acoustic reflection of the shell material of our power armor is very low. There will be great interference in the ocean due to the wave, which further reduces the possibility of us being detected by active sonar. This makes it almost unnecessary for us to worry about sonar problems in water, because it is difficult to find them.

But the environment here is different.

This is a lake. Although it is not a dead water lake, it is only a lake after all. How much background noise do you think a lake can produce?

It's because it's so quiet in the lake that the sonar facilities will work very well here, especially passive sonar. After all, active sonar has to consider the problem of underwater echo, but passive sonar doesn't have to worry about it at all. Although our underwater sound is not big, in the sea can be completely covered by the ocean background sound, but not in the lake.

Originally, we thought that the other party should prepare a few frogmen under the water, and then prepare a few speedboats on the water, but we didn't expect that the other party even got out submarines and underwater robots. This configuration is obviously a bit out of expectation.

What else can I say in the face of this situation?

"Damn it. I don't have any weapons in the water. It doesn't look so easy." Said amenis.

I thought about it a little bit. In the middle of the network of minds, "we're going forward as usual. Since we can't hide it, we'll push it flat."

"Really?" Jingjing asked in surprise.

I confirmed again, "yes, flat push."

"I like the decision." Lingling said excitedly.

"So straight up?" Ling asked some uncertain questions in the mind network."Of course not. The technology still needs some. After a while, we'll play our strengths. "

With the ideas I've conveyed in my mind network, it took you a few seconds to fully understand my arrangements and then move forward.

In fact, we were found immediately after we went into the water. After all, the passive sonar of the other party could clearly hear the sound of any object entering the water. It would be strange if the other party could not hear the sound of a lake. However, just as they were getting closer to us in advance according to the signal, there was a sharp explosion in the water, and all the sonar equipment was destroyed in an instant.

"Damn it!" A Sonarman sitting on a speedboat tugged at his ears as he grinned. His earphone on his head just burst out a sharp whistling sound. His ears are almost deaf now. He can't hear anything if others don't shout.

"What's going on?" When the Sonarman actually took off his earphone, the commander on board would ask about the situation.

Although the sonar saw the boss asking, he couldn't hear him. He didn't hear him until he repeated it three times. Then he replied, "I don't know. The other party used some method we didn't know to make high-intensity underwater noise. Now the sonar system is completely useless."

"Hardware damage?" The commander asked.

The sonar, who had recovered a little hearing, shook his head and said, "no, sonar devices have overload protection, so it's not so easy to have problems. It's just that the noise always exists, so as long as the noise doesn't disappear, our sonar is useless."

"Damn it, they took the lead again."

In fact, if the commander knew what was causing all their equipment to fail, he would have been more manic, because what made their sonar useless was not something complicated, but a lump of ice. Yes, it's ice. It's made from the lake water here. Of course, this piece of ice will not be a simple ice block. It is actually a very standard resonator, and it is specially suitable for underwater use. Its principle is similar to that of the wind whistle installed on the wing tip of a dive bomber, but this one uses the water flow instead of the air flow to make sound. Compared with the wind whistle, the whistle is louder and has a wider frequency, and the tone can be changed by changing the speed of the water flowing through the whistle.

This whistle is made by frost and snow by freezing the lake water with temperature control ability, and the user is the night moon, because she is the fastest underwater speed here. After all, her tail is a good thing, very suitable for water movement.

The night moon runs through the water at high speed with one hand holding two water whistles, and the noise makes all the sonar devices around them 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. Previously, sonar detection was just a wide area investigation. Now that we have identified the target, we have switched to electromagnetic induction.

In any case, submarines and underwater robots must carry a large number of electronic and mechanical equipment, and the electromagnetic signals emitted by these things can not be completely shielded. It's really impossible to find a submarine by relying on the leakage of electromagnetic waves in the ocean, but this is a lake with such a large area. Although the submarines of the other side are all single submarines, it is too easy for us to determine the electromagnetic signals of the other side in such a large place. Even to us, the signal intensity of each other is almost the same as that of a firefly in the dark. Although the brightness of the firefly itself is very low, it is still so conspicuous in the night that it is difficult to pay attention to it.

As for the frogmen To be honest, these guys have a very strong signal. Their brain wave is just like a transmitter, we can clearly receive these people's brain wave signals in the water, not only the location, but also their emotions can be accurately sensed.

Relying on this asymmetric information collection ability, we were very easy to lean on the fastest submarines, and then put a piece of soft glue with the word "plastic bomb" written on the submarine observation window in the surprised eyes of the other party.

What we put on is just a piece of soft glue, but if it's a real battle, it's a real plastic bomb. And we don't stick it to the observation window, we stick it directly to the hull. Since we can stick this thing on the observation window soundlessly, other positions are naturally easier.

The people inside the submarine knew that they were killed when they saw the "bomb", and then according to the rules, they pressed a temporary button. There was a loud boom outside the submarine. Of course, this was from the loudspeaker, which told others that he was "killed".

It's night, and there's nothing to see on the ground. It's needless to say how dark the water can be. The sonar was abandoned, and these people became completely deaf and blind. We got close to them easily and soon lost all the boats and submarines. As for underwater robots It's worse because we've convinced them to surrender.

Dragon people are all experts in electronic warfare, because our brain has some characteristics of electronic computers. Although our electronic brain is actually a quantum computer, it is essentially compatible with electronic equipment. In addition, our electromagnetic control can physically cross some software level things, so it is difficult for computers to have any resistance in front of us. Unfortunately, these underwater robots are automatic robots. If we use wire control models, at most we will paralyze them, but now they are completely rebellious.Because of the robot mutiny, so the frogman army was destroyed. After that, we started shooting directly from the water to the shore by the lake. In an instant, the bullets flew, and then all the defense forces on the shore were destroyed.

No one thinks that we can attack the people on the shore directly under the water. The common sense is that if we want to attack the people on the shore, we should at least take the lead. But we must finish this process underwater, so the people on the shore have no way to fight back effectively. Because we are underwater, the other party can't determine our exact position at all. Moreover, the bullet will deflect when it enters the water. If the inclination angle is not large enough, it will even become a floating bullet. After entering the water, the bullet will bounce again and never enter the water.

Originally, our defense is immune to most weapons. Now we have water surface to help block bullets, but the enemy can't find our exact location, and the firepower is completely random. Under such circumstances, it's really impossible to produce any deterrent force, so the result is that we kill all the other side without even wiping bullets. After all, our electronic brain is pre installed with trajectory calculation software, so even if it is underwater shooting, we still maintain a 90% or more hit rate.

When we go ashore, we look at the colorful "corpses" and we can see how much resentment these people have because their brain waves are about to materialize.

"Xiaochun, give me another scan map." Regardless of the "corpses" around me, I ordered directly from the psychic network.

"Shall I look up?" Xiaochun pointed to the sky.

"No I waved: "Everett, throw two scouts."

Everett had just come out of the water, and his body was still splashing down. Hearing my command, he bent down slightly. Suddenly, two slopes on both sides of his back popped three times in succession. At first, it looked like a flying saucer in an alien movie, but its surface was very smooth without any protrusions, and its surface was smooth It's only twenty centimeters in diameter. The frisbee edge is a circle of blue cold light lines, not very bright, but very beautiful.

It's completely inaudible, and it's very fast and extremely flexible. After being released, it flickered a few times and disappeared completely, but in our mind network, the surrounding topographic map suddenly appeared to be widely updated. Before the electromagnetic scanning, only black and white maps were received, but now it is full-color scanning, and a large red mark is painted in the map area ahead, which is the target found by the micro reconnaissance aircraft, and the number is still rising rapidly.

"Shit, a lot of people!"
