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, so we easily dived underwater.

Although Adina was not brought with us this time, no one else on our side would not use sonar sensing, but Adina was not able to play with her.

Although this lake is not small, it is not particularly large, so when we entered the water, we discovered several targets underwater as soon as the sonar unfolded.

"Underwater target was detected." A large red mark was instantly painted in our spiritual network. These were not fish, because there were not such big fish in this lake.

From the information feedback from the sonar, it can be seen that these targets in the lake are roughly divided into three types. The first one is a particularly large signal, and it is a small submarine. Yes, that's right, it's a small submarine. Although I don't know when these submarines were brought here.

The second type of feedback signal is slightly smaller than that of the submarine, and it is initially judged as a submersible robot. The third type of signal is smaller in size and should be a frogman.

The feedback signals of the three goals are completely different, so we can easily analyze which goals are, but the number of these goals 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 actually reminding me, but asking me if I need to retreat to the shore. After all, we cannot hide ourselves in the water. Although the power armor on our body is very 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, the function of not installing sonar shielding is not that we do not have similar technology, but that we did not expect to install such things. Everyone knows that sonar is actually a technology that relies on the reflection of sound by objects to position it. The size of the reflected sound wave is mainly related to the size and material of the target itself. Of course, passive sonar is another technology, which is actually very different from active sonar.

Generally speaking, submarines rarely start active sonar underwater. This is mainly because the sound generator of active sonar is simply a super big light bulb for passive sonars, and can be found from a distance. Although the ability of active sonar to search targets is stronger than passive sonars. However, 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 of submarines in two countries colliding underwater, because no one dares to turn on active sonars, and the silent technology of military submarines is relatively good. Therefore, neither submarines turn on active sonars, just like even holding their breath and letting their feet move carefully in a dark room. Everyone does not make a sound. The room is too dark and there is no wonder that they will collide.

Because we generally don’t turn on active sonars. We are dragons, not submarines, and our propulsion sound in the water is much quieter than submarines, and it is impossible to be discovered by passive sonars. Therefore, our demand for sound wave absorption materials is not strong. Besides, even if the other party turns on active sonars, we are so large, and many fish in the sea are larger than ours, so the sound wave signals we reflect will definitely not be strong. It is difficult for the sonars to distinguish us from dolphins and other things.

, This further reduces the need for sonar camouflage. Besides, our armor only does not have a special coating for sonar absorption, which does not mean 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 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 problems in water, because it is difficult to discover them.

However, the environment here is different.

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

It is because the lake is too quiet, so the effect of sonar facilities here is very good, especially passive sonar. After all, active sonar must also consider the issue of bottom-water echo, but passive sonar does not have to worry about these at all. Although our sound underwater is not loud, it can be completely covered by the background sound of the ocean in the sea, but it cannot be done in the lake.

We originally thought that the other party was preparing at most a few frogmen under the water and then preparing several speedboats on the water, but we didn't expect that the other party even made out submarines and underwater robots. This configuration was obviously a bit beyond expectations.

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

"It's so damn. I didn't even bring any weapons in the water. It doesn't seem so easy to deal with." Emmenis said.

I thought for a moment and said in the spiritual network: "We move forward as usual. Since we can't hide it, then just push it flat."

"Really push it?" Jingjing asked in surprise.

I confirm again: "Yes. flat push."

"I like this decision." Lingling said excitedly.

"Are you just going directly?" Ling asked in the spiritual network with some uncertainty.

"Of course not. If the flat push is flat push, the technology still needs some. We will use our specialties later."

As I conveyed my thoughts in the spiritual network, it took me a few seconds to fully understand my arrangement and then start moving forward.

In fact, we were immediately discovered after we got into the water. After all, the other party's passive sonar could clearly hear the sound of any object being put into the water. A lake was so loud, it would be strange if the other party could not hear it. However, just as they gradually approached us as they were moving forward according to the signal, a harsh explosion suddenly came from the water, and then all the sonar equipment was completely destroyed in an instant.

"Damn it!" A sonar sitting on the speedboat grinned while trying hard to clean his ears. The headphones he was carrying on his head suddenly made a sharp roar in the explosion, which made his ears almost unable to hear the sound. If others didn't shout loudly, he could not hear anything.

"What's going on?" The sonar actually took off his headphones, so of course the commander on the ship had to ask about the situation.

Although the sonar saw the boss asking questions, he couldn't hear it at all. He didn't hear it clearly until the other party repeated it loudly three times, and then replied: "I don't know, the other party used some method we didn't know to create high-intensity noise underwater. Now the sonar system is completely useless."

"Hardware is damaged?" the commander asked.

The sonar who had recovered some of his hearing shook his head and said, "No, the sonar device has overload protection. It's not that easy to have problems. It's just that the noise always exists, so as long as the noise does not disappear, our sonar is equivalent to being scrapped."

"Damn it, they took the lead again."

In fact, if the commander knew what made all their equipment fail, he would probably be even more manic, because what was scrapped all their sonar was not a complicated thing, but a piece of ice. Yes, it was the ice cube, which condensed from the lake water here. Of course, this ice cube would not be a simple ice cube. 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 installed on the wing tip of a dive bomber, but this is a sound using water flow rather than air flow. Compared with that kind of wind whistle, this water whistle has a louder sound and a wider frequency, and the tone of the sound can be changed by changing the speed of water flowing through the whistle.

This whistle was made by Frost and Snow using temperature control ability to freeze the lake water, while the user was Ye Yue, because she was underwater speed here for us. After all, her tail is really a good thing. It is very suitable for moving in the water.

Ye Yue was underwater, holding two water whistles in one hand and walking through the water at high speed, and this noise made all the surrounding sonar devices lose their function. However, although the other party's sonar has lost its function, we are not affected by any influence, because we did not rely on sonar to determine the target at all. The previous sonar detection was just wide-area reconnaissance. Now that the target has been determined, we have changed to electromagnetic induction.

Submarines and underwater robots must carry a large number of electronic and mechanical equipment no matter what, and the electromagnetic signals emitted by these things cannot be completely blocked. In such a scene with a huge range in the ocean, it is indeed unlikely to find a submarine by relying on these leaked electromagnetic waves, but this is a lake, with such a large area. Although the other party’s submarines are all single-person submarines, it is too easy for us to determine the other party’s electromagnetic signals. Even for us, the signal strength of the other party is almost the same as that of the fireflies in the night. Although the brightness of the fireflies itself is very low, it is still so conspicuous in the night, and it is difficult not to pay attention.

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

Relying on this asymmetric information collection ability, we easily leaned against the fastest submarines, and then put a piece of soft rubber with the word "plastic bomb" on the submarine observation window in surprise and ignored it.

All we paste on is a piece of soft glue, but if it is a practical battle, this is a real plastic bomb. And we will not paste it on the observation window, but will directly paste it on the hull. Since we can silently paste this thing on the observation window, it is naturally simpler to other locations.

When the people inside the submarine saw this "bomb", they knew that they had died. Then, according to the rules, they pressed a temporary button. A loud bang immediately outside the submarine. Of course, this was emitted by the speaker, which told others that he had "dead".

It's night now, and there is no way to see things on the ground. It goes without saying how dark it can be underwater. The sonar was destroyed, and these people became deaf and blind. We easily approached each other and soon lost all their ships and submarines. As for the underwater robots... it's even worse, because they were persuaded to surrender by us.

The Dragon Clan is all electronic warfare experts, 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 controls can physically cross certain software levels, so it is difficult for computers to have any resistance in front of us. These underwater robots are unlucky because they are automatic robots. If they are wire-controlled models, we will at most paralyze them, but now they are completely rebellious.

Because of the robot's rebellion, the frogman troops were wiped out. Then we started shooting directly from the water on the shore. In an instant, bullets flew across the board, and then the defensive troops on the shore were wiped out.

No one wants us to attack people on the shore directly under the water. The general common sense is that we should at least attack people on the shore, but we just completed this process under the water, so people on the shore have no way to effectively fight back. Because we are under the water, the other party cannot determine our exact position at all, and the bullet will deflect at a certain degree of deflection when entering the water. If the inclination angle is not large enough, it will even become a floating bullet. After entering the water surface, the bullet will bounce again and will not enter the water at all.

Originally, our defense is immune to most weapons. Now that the water surface helps block bullets, the enemy cannot find our exact location, and the firepower is completely fired. It is really impossible to generate any deterrent force in this case, so the result is that we kill all the opponent without even having any bullets. After all, our electronic brain itself is pre-installed with ballistic computing software, so even if we shoot underwater, we still maintain a hit rate of more than 90%.

When we went ashore, we looked at the colorful "corpses" and knew how much resentment these people were, because their brain waves were about to become substantial.

"Xiaochun, give me another scan map." Ignore the orders in the surrounding "corpses and mind network."

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

"No." I waved my hand: "IFREET, throw two reconnaissance planes."

As soon as Everett came up from the water, he was still dripping down. When he heard my order, he immediately bent down slightly. On the two inclined surfaces on both sides of his back, three round pancake-like gadgets popped up in three consecutive sounds. This thing looked very similar to the UFO in an alien movie, but its surface was very smooth and had no protrusions, and its diameter was only twenty centimeters. The edge of this UFO was a circle of blue cold light, which did not look very bright, but was very beautiful.

This thing can't hear any sound when flying, and it's very fast and very flexible. After being released, it flashed a few times and disappeared completely, but the topographic map around our spiritual network suddenly appeared in large-scale updates. The previous electromagnetic scan only received a black and white map, but now it is a full-color scan, and a large red mark was flashed in the map area ahead. This is the target discovered by the micro-reconnaissance aircraft, and the number is still rising rapidly.

"Damn, so many people!" (To be continued.)
