Alien Girl Development Guide

Since sound waves are used as a means of communication, it is still within the understanding of rabbits, at least not the more difficult to decipher pheromone and spectral changes.

The pheromones exchanged between insects can kill human beings. After all, some pheromones cannot be artificially synthesized until now!

The propagation speed of sound waves underwater is greater than that of air, but there is still some understanding of the frequency of sound waves in the starfish civilization. After all, there are some frequencies of sound waves that human ears cannot see, such as the cry of whales.

Therefore, the submersible will release sound waves of different frequencies underwater, trying to find a frequency that can communicate with the starfish civilization. The same name will record the submersible’s release of different frequency bands of sound waves through the onboard electronic equipment, and record them according to the other party’s response. It would be even better to crack the communication method of starfish civilization.

Regarding the contact between the two parties, although the first time was not very "pleasant", the other party, as a civilization capable of dominating the Abyss Sea, and a survivor of a higher civilization that once fought with land civilizations, has no mathematical ability. will be weak.

The contact between two different civilizations is not only a competition of hard power, but also a competition of soft power. Mathematics is the best way for two different civilizations to contact. After all, numbers do not lie. If you can't do it, you can't do it.

The unmanned submersible vehicle thrown by the Qingluan fighter plane slowly fell towards the sea surface. When it was 50 meters away from the sea surface, the retarder parachute at the tail opened, slowly fell towards the sea surface, and finally smashed into the sea with a plop.

As the submersible enters the water, the internal electronic components start to work, and the high-frequency sound waves spread out in all directions.

Sound waves are not only a means of communication, but can also be turned into weapons. Rabbits can still use high-frequency sound wave weapons underwater, and use powerful torpedoes or more lethal ruthless weapons in the deep sea. It is a question that is not considered until a full-scale war is launched.

(((Hey!)))

The propagation speed of sound waves in water is much faster than that of air, and soon the sound waves released by the unmanned submersible will spread to the surroundings.

As the base camp of starfish civilization, the rabbit believes that the other party will definitely be able to hear it. As for whether it will respond to the communication, it depends on the other party's attitude.

Chapter 2 Where is the starfish civilization~

(((Hey!)))

(((are you there?)))

(((I have something to do with you!)))

The three torpedoes continuously released superfrequency sound waves underwater, trying to let the starfish civilization hear them, and then make a fool of themselves.

人耳可以听到的声波的频率是20Hz-20KHz，低于20Hz的称为次声波，高于20KHz的称为超声波。正常鲸的频率是15-25Hz，但是我们可以借助仪器将它的声音转换成我们可以听见的声音。

The submersible can not only release ultrasonic waves underwater, but also monitor any infrasonic and ultrasonic waves underwater...

Time passed by every minute and every second, and there was still no response below the sea level, and even the sea beasts that usually heard the sound did not show up...

However, if the starfish civilization continues to stay on the bottom of the sea, then the rabbit really has nothing to do.

"Eagle's Nest...Eagle's Nest...here is Chongming, the starfish did not respond to the ultrasonic wave...repeat..."

The bird of the same name, who was watching in the sky, reported what happened here to Pengkun No. [-], waiting for instructions from Pengkun No. [-].

At the same time, in the frontline command room of Pengkun [-], members of the combat team were having an abnormal meeting.

"What do you think about this matter?"

On the LED screen, the situation in the deep sea is played in real time. In addition to the same name, the low-orbit satellite and the high-orbit staring satellite are also paying attention to the deep sea.

"Do you want to knock on the door more intensely?"

Perhaps it is because the ultrasonic waves emitted by the submersible are too gentle, and the starfish civilization has no intention of answering them. After all, from a certain point of view, they are descendants of higher civilizations, and they may not want to answer the call of "lower" civilizations.

"Let's drop the depth charges with N2 warheads...see their reaction?"

The boss thought about it, this suggestion is a little bit "radical". After all, throwing a "big firecracker" at someone's door is a bit too ironic, so we should delay this proposal for a while.

"This suggestion is the last option..." the boss said softly.

"Is it not deep enough?" An expert thought for a while and said: "The depth of the starfish may be much deeper than we imagined. Why don't we let the depth of the submersible continue to dive."

Although the propagation speed of ultrasonic waves underwater is greater than that in the air sink, there is still a limit to the propagation distance.

The people present looked at it and thought it made sense, but an unmanned submersible that can dive to a sufficient depth is not something that Chongming can carry.

"Let the Xiyang base launch a large submarine."

"clear."

Soon, the order of Pengkun No. [-] was sent to Xiyang Base.

In the permanent fortifications of Shangqiu Military Base and Xiyang Frontier Base, special underground silos were opened to both sides, revealing the "fat tiger" of the DF family inside. With the ignition of the rocket engine, the fat tiger roared and flew towards The sky then flew towards the direction of the abyssal sea.

At this time, the delivery speed of DF Express is relatively fast~

Driven by the rocket engine, the multiple Dongfeng expresses quickly flew towards the predetermined coordinates... The multiple Dongfeng Express launched this time will fly to the abyss and be distributed throughout the abyss.

There are two purposes, one is to expand the search range after spreading out; the other is to use multi-point positioning method to find the area where starfish civilization exists or the range of activities, and prepare for another communication method in the future !

After the thick projectile flew to the target area, the combat part separated, and the parachute opened and slowly fell toward the sea surface. At a distance of 10M from the sea surface, the fairing of the warhead split to both sides, exposing a large unmanned 1200MM inside. submersible.

Pfft!

A large unmanned submersible falls into the water. After sensing the sea water, the internal module is activated. The rear part of the unmanned submersible is separated and automatically inflated, becoming a buoy that can float on the sea surface, while the separated front half quickly sinks toward the seabed. go.

On the top of the buoy, the LED lights flashed, proving that its working status was normal, and it was linked with Chongming, satellites, Xiyang base in the sky, and even the Shangqiu headquarters through a data link.

drop!drop!drop!

The large deep submersible sinks continuously towards the deep sea, and is connected to the buoy on the sea surface through a 0.3MM thick optical fiber data cable, and the data is sent to the buoy, and then sent to the command system through the buoy.

In the electronic sand table, the coverage of each large deep submersible is displayed on it, followed by a long waiting time.

While the large deep submersible releases ultrasonic/infrasonic waves in stages, it will also listen to other underwater sounds when the sounding device switches frequency (stops).

If the Starfish Civilization Array is active during sleep, it will definitely leave some clues.

Tick...tick...time passed by every minute and every second, half an hour passed, and there was no sound in the deep sea.

One hour...

two hours...

When the time reached 1600, the entire abyss was still abnormally calm, and even the sea beasts that usually appeared were gone.

The people in Pengkun No. [-] command room glanced at each other and frowned slightly.

"I think the starfish civilization must have received the ultrasonic waves we sent..."

All the experts present agreed on this point. The starfish civilization definitely received the human call, but the other party did not answer.

"Why didn't they answer?" the commander looked at the experts and asked softly.

The commander still attaches great importance to the suggestions of these experts, after all, the things they came into contact with this time are not human beings.

After grabbing the door and discussing with each other, the leading expert looked up at the commander and said:

"I don't know, because we don't belong to the same species as the starfish civilization, we don't know what they are thinking..." The expert said helplessly, the conclusion drawn by human thinking is too one-sided.

"...However, to root out our discussion, it is not that they cannot answer, but that they do not want to answer, and they are worried about exposing their position."

In the vast abyss, the starfish civilization hides in the deep sea that humans cannot find out, which is equivalent to covering the body with a layer of "fog of war" and hiding itself in darkness.

The first requirement of species is survival. In this dark deep sea, exposure means being swallowed by other prey.

The deep submersible launched by the rabbit is equivalent to a large sonar transmitter. It can locate the location of the starfish civilization through the echo, and then humans will have a way to attack the proven area!

Simply put, the starfish civilization does not believe in Homo erectus.

Chapter 3 Vehicles of Ancient Civilization (repaired, please click on the upper right corner to refresh)

To put it simply, it is a chain of suspicion, the starfish civilization does not believe in the erect ape!

"Is there any way to make the other party speak?" The commander asked after thinking about it.

"It's difficult, because we don't know the communication frequency of the starfish civilization, and the meaning of each sound wave, so we can only pass the test..."

"...We don't have any living starfish civilization individuals, so we can only keep testing..."

This point is relatively unsolvable. After all, even if you want to solve a math problem, you must give certain conditions.

"Then continue to monitor underwater until the submersible self-destructs."

That's right, these unmanned submersibles have their own self-destruct devices. It is impossible for rabbits to let the starfish civilization obtain their own technological products. Therefore, whether it is the launched DF express or the submersible, after use, the core parts will to self-destruct...

In the next few hours, the submersible continued to emit sound waves of various frequencies underwater, and the starfish civilization remained silent.

"How long can the internal battery of our submersible last?"

"24 hours..."

The commander nodded. This is also the result obtained after upgrading the superconducting battery. It can only take half an hour to replace the submersible with the previous submersible. After all, it is too power-intensive to emit ultrasonic waves of different frequencies!

Next, we need to wait for a long time, hoping that the starfish civilization can give some feedback... maybe.

At the same time, experts in the special scientific research institute of the Xiyang base are conducting research on the artifacts of ancient civilizations salvaged from the abyss.

The vehicle of this ancient civilization is obviously different from the vehicle of the starfish civilization. The biggest difference is the difference between the shell material of the ancient civilization and the shell material of the starfish civilization.

Regarding how the starfish civilization carried out metal smelting, experts have given a lot of conjectures. After all, the two civilizations live in different ways, and they can only give some conjectures before seeing it.

The first one is volcanoes passing through the seabed, but because of the existence of seawater, the temperature of submarine volcanoes is limited. This conjecture is not very likely... But it does not rule out that starfish civilization has special technology. Simply put, it is possible, but Not entirely possible.

The second is to condense high-performance metals through chemical methods. Humans have limited research on smelting metals through chemical methods. After all, most of the technology trees with little human skills are high-temperature metal smelting.

The third is the method of biosynthesis. Although it is a bit exaggerated, organisms can also be synthesized. After all, who knows if there are any special sea beasts that can synthesize metals, such as the scaly-horned gastropod snails that live in the sea.

This magical snail scale-horned gastropod not only has iron-containing scales on its abdomen, but also has three layers of shell.Moreover, Scale-horned gastropod snails often live near hot springs on the seabed, and the hot spring water ejected from the seabed is rich in iron sulfur and ferrous sulfide.

When the snail moves around here, the shell will be continuously polished with these substances, and finally a special alloy film will be formed, which makes its shell extremely hard.

Fourth, the help of foreign objects, such as the goddess's treasure.

......

In addition to these conjectures, there are some other conjectures. When the experts open their heads, there will be nothing for ordinary people.

"Experiment record preparation!"

Several experimenters said to the four-axis 4K high-definition four-axis rotorcraft on the side. The four-axis rotorcraft flew up after receiving the command, and pointed the camera at the ancient civilization vehicle that was fished out of the sea.

The two researchers first cleaned the shell of the ancient civilization vehicle, cleaned up the sediment attached to the shell, observed the ancient civilization vehicle for a week, and compared the starfish civilization projected by the four-axis rotorcraft The appearance of the aircraft, came to a conclusion: this vehicle is not a creation of starfish civilization!

Civilizations and civilizations have different aesthetics, so things created by one civilization may look ugly to another civilization. For example, vehicles made by green-skinned orcs may look like a pile of rubbish put together in the eyes of other civilizations. Together, it becomes large self-propelled garbage.

Or the space-mobile junk of Minmatar...

The details of the ancient civilization creation in front of me are completely different from the starfish civilization. Even if the starfish civilization declines, certain things will continue.

"For the record, this vehicle is likely to be a creation of the ancient civilization of Star Mingrui..."

"Understood~Record completed~"

A nice female voice came out from the four-axis drone, which can be regarded as a kind of rabbit’s use of artificial intelligence. With the introduction of fractal silica and grating stone materials, rabbit’s computer technology has advanced by leaps and bounds. Mental retardation gradually transforms into artificial intelligence.

With the continuous improvement of artificial intelligence, it has gradually been added to all aspects of rabbit life.

Rabbit already has controllable nuclear fusion, and quantum computers are constantly being upgraded. At least they have touched the threshold of a real quantum computer. Communication technology is also taking several steps. 7G and 8G are under development... and artificial intelligence technology Also advancing by leaps and bounds.

According to the discussion of the experts, the rabbit is far from kicking the door of the fourth industrial revolution, only the accumulation and precipitation of time is left, and the door will come soon!

After the AI ​​finished recording the data, it uploaded the data to the database of Xiyang Base through the high-speed wireless network for backup.

Several scientific researchers looked at each other, and finally locked their eyes on the hole on the surface of the vehicle. The scientific researcher stepped forward to observe the edge of the hole, and there were traces of melting...that is to say, it did not exist when it was manufactured. It is caused by being hit by some kind of weapon.

Then what this weapon is is about to come out, the high-energy laser of the starfish civilization.

"Prepare the pinhole probe..."

Soon, after the slender pinhole probe was ready, it was inserted along the broken hole, and the LED light on the top of the probe illuminated the inner space.

"Well... the structure is exquisite..."

The interior design of the aircraft is obviously much more complicated than that of the starfish civilization. There are many components that seem to be made of "crystals". The first thing that comes to mind is the shining stone mined by the mainland civilization.

"Continue to go deeper..."

Like a gastroscope, the pinhole camera goes deep into the interior along the hole and records what it sees.

Outside the laboratory, the experts watched the video transmitted by the vacuum camera, and couldn't help being a little surprised. The high-energy laser almost became a light spear, almost burning through the entire aircraft!

"Hiss... the power of this laser is greater than we imagined. Sure enough, the technology of the starfish civilization has also declined. If the starfish civilization in the previous conflict had this kind of technology, our frigate may not be able to return..."

Chapter 4 is 100 million words!

"continue..."

The researchers carefully inserted the pinhole probe into the ancient civilization vehicle.

Through the holes pierced by high-energy lasers, the state of the interior of the aircraft can be seen.
