Starting from Zero

The process of entering the water is of course very simple. The side where we are located is still quite far away from the villa, so the distribution of people is not particularly dense, and we easily dive into the water.

Although I didn't bring Ayana this time, it's not that other people on our side don't use sonar to sense, but there is no Ayana to play.

Although the lake is not small, it is also not particularly large, so when we entered the water, the sonar immediately unfolded and found several underwater targets.

"Underwater target detected." A large red mark appeared in the spirit net network of our heart. These are not fish, because there are no such big fish in this lake.

From the information returned by the sonar, it can be seen that these targets in the lake are roughly divided into three types. First is the signal with a particularly large signal, and it is initially judged to be a small submarine. Yes, yes, it is a small submarine. Although I don't know when these submarines were acquired.

The second feedback signal is slightly smaller than that of a submarine, and it is initially judged to be a diving robot. The third type signal is smaller and should be a 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 looks a little scary.

"Master, we can’t use the mirage system in the water. If the other party uses active sonar, we definitely can’t hide ourselves." Xiaochun’s words are actually not reminding me, but asking if I need to return Go to the shore, after all, we have no way to hide ourselves 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 that this thing does not have is the sonar shielding function.

In fact, not installing the sonar shielding function is not that we don't have similar technology, but originally didn't expect to install this thing. Everyone knows that sonar is actually a technology that relies on the reflection of sound from an object for positioning. The size of this reflected sound wave is mainly related to the volume and material of the target itself. Of course, passive sonar is another technology, which is actually quite different from active sonar.

Generally speaking, submarines rarely activate active sonar under water. This is mainly because the sound wave generator of active sonar is simply a super-large light bulb for passive sonar. Can find out. Although the ability of active sonar to search for a target is stronger than that of 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 has been an underwater collision between the two submarines before, because everyone is afraid to use active sonar, and the mute technology of military submarines is relatively good, so neither submarine makes active sound. Na, it's like even a person moving carefully in a dark room holding their breath and walking lightly. Everyone doesn't make any noise. The room is too dark and nothing can be seen. There is nothing strange about bumping into each other.

Because people generally will not use active sonar, and we are Dragon Clan, not a submarine, our propulsion sound in the water is much quieter than a submarine, and it is impossible to be discovered by passive sonar. Our demand for acoustic wave absorbing materials is not strong. Besides, even if the other party opened the 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 too strong. It is difficult for sonarists to separate us from the eastern Western Region such as dolphins. This further reduces the need for sonar camouflage. Besides, our armor is just a special coating without sonar absorption, not to say that there is no such design at all. In fact, the sound wave reflection of the shell material of our power armor itself is very low, and there will be great interference in the ocean due to the waves, which further reduces the probability that we are discovered by active sonar. This determines that we almost don't need to worry about sonar problems in the water, because it is also difficult to find out.

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 produce?

Because the lake water is too quiet, so the effect of sonar facilities here will be very good, especially passive sonar. After all, active sonar also takes into account the problem of underwater echo, but passive sonar does not have to worry about these at all. Although our underwater sound is not loud, it can be completely masked by the background sound of the ocean in the sea, but it is not good in the lake.

Originally, we thought that the other party would prepare a few frogmen underwater at most, and then prepare a few speedboats on the water surface. We did not expect that the other party would even get out submarines and underwater robots. This configuration is obviously a bit beyond expectations.

What can I say in the face of this situation?

"Damn it, I didn't bring any weapons in the water, it doesn't look so easy to handle." Emiennes said.

I thought about it for a while and said in the spirit net network: "We move forward as usual. Since we can't hide it, let's push it flat."

"Really push? Jingjing asked in surprise.

I confirm again: "Yes, flat push."

"I like this decision." Lingling said excitedly.

"Is it that way?" Ling asked in the spirit net network with some uncertainty.

"Of course not. I still need some technology. We will give full play to our expertise in a while."

With the thoughts conveyed in, it took a few seconds for everyone to thoroughly understand my arrangement, and then began to move forward.

In fact, the place immediately found us after we got into the water. After all, the other party’s passive sonar can clearly hear the sound of any object entering the water. A lake is so big. If the other party can’t hear it, it’s called. It's strange. However, just as they gradually approached us according to the signal, there was a sudden piercing blast in the water, and then all the sonar equipment was completely wiped out in an instant.

"Damn it!" a sonarman sitting on the speedboat scolded while plucking his ears desperately. The earphones he put on his head just suddenly made a sharp squeal in the explosion, and his ears that blew up almost couldn't hear the sound now, and he couldn't hear anything if others didn't shout loudly.

"What's the matter?" When the sonarman actually took off the earphones, the commander on board had to ask about the situation.

Although the sonarman saw the boss questioning, he couldn’t hear it at all. He didn’t hear clearly until the other party repeated it three times aloud, and then replied: "I don’t know, the other party uses a method we don’t know. High-intensity noise was created underwater, and now the sonar system is completely useless."

"Hardware is damaged?" the commander asked.

The sonar player who has recovered some hearing shook his head and said: "No, the sonar device has overload protection. It is not that easy to cause problems. It is just because the noise is always there, so as long as the noise does not disappear, our voice It’s abolished."

"Damn it, they have taken advantage of it again."

In fact, if the commander knew what caused their equipment to fail. In terms of things, it is estimated that he will definitely be more manic, because it is not something complicated that makes their sonars scrapped, but a piece of ice. Yes, it's ice cubes, ice cubes condensed from the lake water here. Of course, this ice cube will not be a simple ice lump. It is actually a very standard resonator, and it is a resonator specially suitable for underwater use. The principle is similar to the wind whistle mounted on the wingtip of a dive bomber, but this It uses water currents instead of air currents to make sound. Compared with that kind of wind whistle, this water whistle has a louder sound and a wider frequency, and the pitch of the sound can be changed by changing the speed of the water flowing through the whistle.

This whistle is made by Frost and Snow using the temperature control ability to freeze the lake water, and the user is Yeyue, because she is the fastest underwater in our place, after all, her tail is really good Something is very suitable for moving in the water.

Under the water, Yeyue is holding two water whistles one by one and walking through the water at high speed, and this noise makes the surrounding sonar devices all useless. However, although the other party's sonar has no effect, we are not affected in any way, because we simply do not rely on sonar to determine the target. The previous sonar detection was nothing more than a wide-area reconnaissance. Now that the target has been determined, we have changed it to electromagnetic induction capability.

Submarines and underwater robots must carry a lot of electronic and mechanical equipment anyway. The electromagnetic signals emitted by these things are impossible to completely shield. In a scene with an extremely large range in the ocean, it is indeed impossible to find a submarine by relying on this leaked electromagnetic wave, but this is a lake with such a large area. Although the opponent's submarines are single-man submarines, it is too easy for us to determine the electromagnetic signal of the opponent in such a large area. Even for us, the signal strength of the other party is almost the same as the firefly in the dark. Although the brightness of firefly itself is very low, it is still so conspicuous in the dark, it is difficult to not pay attention.

As for those frogmen... to be honest, these guys have super strong signals. Their brain waves are exactly like transmitters. We can clearly receive the brain wave signals of these people in the water. Not only the location, but also their emotions can be accurately sensed.

Relying on this asymmetrical information gathering ability, we easily leaned on the fastest submarines, and then in the other’s surprised eyes, the word "plastic bomb" was written on a piece of it. Put the soft glue on the observation window of the submarine and leave it alone.

What we posted is just a piece of soft glue, but if it is actual combat, this is a real plastic bomb. And we will not stick to the observation window, but directly on the hull. Since we can stick this thing on the observation window silently, other locations are naturally easier.

People in the submarine knew that they were killed when they saw this "bomb", and then according to the rules, they pressed a temporary button. There was a loud explosion sound from the outside of the submarine. Of course, this was from the loudspeaker, telling others that he was "dead".

It is night now, and nothing can be seen on the ground. Needless to say how dark the underwater can be. The sonar was abolished, and these people became deaf and blind. They were easily approached by us, and soon lost all their ships and submarines. As for underwater robots... even worse, because they were persuaded to surrender.

Dragon Clan are all electronic warfare experts, because our brains have some of the 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 software levels, so it is difficult for computers to have any resistance in front of us. Unlucky for these underwater robots is that they are automatic robots. If they are wire-controlled models, we would at most paralyze them, but now they have completely rebelled.

Because the robots rebelled, the frogman army was wiped out. After that, we were on the lakeside and started shooting directly at the shore from the water. In an instant, the bullets flew across, and then all the defensive troops on the shore were wiped out.

No one wants us to attack people on the shore directly under water. The general common sense is that we should attack people on the shore at least, but we do it underwater. This process, so people on the shore have no way to effectively fight back. Because we are underwater, the other party is totally unable to determine our exact position, and the bullet will deflect to a certain extent when entering the water. If the inclination is not large enough, it will even turn into a floating bullet. After entering the water, the bullet will bounce again without entering the water at all.

Originally, our defensive power is immune to most weapons. Now there is water surface to help block bullets, and the enemy can’t find our exact position. The firepower is completely indiscriminate. What kind of deterrence will be produced in this situation? It was impossible for Li Zhenxin, so the result was that we killed the other side without even grazing. 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 went ashore, looking at the dreaded "corpses", we knew how great the grievances of these people were, because their brain waves were about to materialize.

"Xiaochun, give me another scan map." Ignoring the "corpses" around me, I directly ordered in the spirit net network.

"Do you want me to go up and take a look?" Xiaochun pointed to the sky.

"No need." I waved: "Ifrit, throw two reconnaissance planes."

Iverrit just came up from the water, still crash-bang. When I heard my order, I bend down slightly. The puff puff puff on the two slopes on both sides of the back suddenly bounced three times like bauble like three round biscuits. This thing looks very similar to the outside at first glance. The flying saucer in the star movie, but its surface is very smooth, without any protrusions, and its diameter is only twenty centimeters. The edge of this little flying saucer is a circle of blue cold light, which does not look very bright, but it is very beautiful.

When this thing flies up, there is no sound at all, and it is very fast and extremely flexible. After being released, it disappeared completely after a few flashes, but the surrounding Terrain Map in the spirit net network of our heart suddenly undergoes a large-scale update. The previous electromagnetic scan only received a black and white map, but now it is a full-color scan, and a large red mark is swiped out in the map area ahead. This is the target discovered by the micro-reconnaissance aircraft, and the number is still rising rapidly.

"I rely on, many people!"
