It's reasonable for me to have a two-way foil for a second-level civilization, right?

"It turns out that the problem is here!"

But Meng Lu on the side still looked confused.

Her main research direction is language, and she doesn't understand the purpose of Lu Yongchang's doing so.

"This is the ultrasonic frequency used by the giant fish to detect the surrounding environment. You can simply understand it as the background noise in their speech."

Lu Yongchang didn't look back, and explained directly.

"Being in the deep sea, they can only rely on ultrasound to perceive the surrounding environment, but this also presents a problem."

"How should they communicate when sensing their environment?"

"You can't take the risk of being 'blind' to communicate with your companions, right?"

"So, they evolved this unique language system."

Meng Lu suddenly realized, and took Lu Yongchang's words: "On the basic ultrasonic wave that plays a role in perception, superimpose ultrasonic waves of other frequencies, and use frequency fluctuations to transmit information!"

"Unfortunately, humans cannot hear these ultrasonic waves."

"Otherwise, there might be a beautiful music that comes and goes as they communicate."

Lu Yongchang nodded noncommittally.

As Meng Lu said, this possibility does exist.

If you replace these ultrasonic waves with audio that can be heard by human ears, then when these giant fish are talking, you will hear pure music that fluctuates up and down, without any lyrics.

Of course, whether the music is good or not depends on one's luck.

Some words sound like fairy music, while others sound like the screeching noise of scratching glass.

But anyway, as long as enough words are said, they can eventually deduce a beautiful tune.

Just like letting many monkeys hit the keys of a typewriter at will, it is possible to write an epic masterpiece in the end.

Lv Yongchang withdrew his scattered thoughts, and turned his attention to the holographic image again.

For some reason, when observing the "sentences" composed of those phonemes, he always felt a little weird.

He frowned slightly, staring at the holographic projection.

After pondering for a moment, he spoke again: "There seems to be something wrong with the phoneme arrangement of these giant fish..."

Meng Lu cheered up and nodded immediately: "Professor, have you also noticed this phenomenon?"

"There seems to be no so-called grammar in their language system."

As she said that, she opened another holographic image with a puzzled face: "Professor, look, this is the sound made by the leader of the giant fish when he urged his companions."

"According to statistics, a total of 43 voice clips were produced during this period, and the duration of each voice clip was about 2.1-2.3 seconds."

"Theoretically, these audio clips should be telling the same thing."

Lu Yongchang nodded slightly.

As it should be.

"There's a problem." Meng Lu stretched out her hand again to swipe on the holographic projection, "These 43 voice clips have the same phoneme."

"These phonemes form short and long syllables, and like phonemes, these syllables are also present in 43 speech fragments at the same time."

"but!"

"The order of these syllables is not consistent, they seem to be arranged randomly." Meng Lu shrugged and said helplessly, "At least Zero didn't find any rules."

"This strange phenomenon occurs in many speech clips."

"I suspect, therefore, that there is no grammar at all in their language."

Lu Yongchang frowned suddenly: "Then how did they understand what their companions said?"

"Without a fixed grammar, it is bound to cause unnecessary misunderstandings."

"This is undoubtedly fatal for a species."

Meng Lu hesitated for a moment, then said slowly, "This may have something to do with the way they speak."

"Through data processing, I found that many of the more than [-] voice clips are repetitive."

"When they talk, they may repeat themselves over and over."

"Different syllables are arranged and combined with each other until the other party understands them thoroughly."

"...repeater?" Lu Yongchang twitched the corner of his mouth, subconsciously complaining.

Meng Lu stared blankly at Lu Yongchang, this sentence broke the inherent impression of Lu Yongchang in her mind.

She nodded with difficulty: "To some extent, it is indeed a bit like a repeater."

Although it sounds unbelievable, in Lu Yongchang's view, this is not an incomprehensible phenomenon.

After all, studies have shown that the order of Chinese characters does not necessarily affect reading. For example, after you read this sentence, you find that the characters in it are all messed up.

Maybe the brains of these giant fish have similar functions?

However, for humans, this is not good news.

Although it is not clear how these giant fish understand this irregular language, it undoubtedly adds a lot of difficulty to the Academy of Sciences' subsequent deciphering work.

"Let's sort it out first."

Lu Yongchang pondered for a moment, then said slowly: "At least, first find out all the same syllables, and then analyze the meaning of them according to the video."

Meng Lu nodded helplessly.

"I'm afraid that's the only way to go."

Although there is zero help, the workload of this "stupid method" is still extremely large.

At least, in the next week, Meng Lu might have to work overtime in the laboratory.

Chapter 487 Skin or Armor?

After solving the problem of the language system, Lu Yongchang and Mao Zhengzhi returned their attention to the giant fish's skin.

Looking at the various detection data in the holographic projection, the two fell into silence together.

"This is definitely not something that can grow from a living body." Mao Zhengzhi said confidently, "If this thing grows naturally, I will go directly to the ice giant to eat a giant fish!"

Lu Yongchang: "...Are you sure?"

Perhaps thinking of the flag that Academician Cao Liangcai set up back then, Mao Zhengzhi raised his hand and touched the tip of his nose with a guilty conscience when he saw Lu Yongchang's teasing gaze.

"Are you sure... are you sure?"

"Anyway, I don't believe that organisms made of cells can grow this alloy from their bodies!"

"Don't forget, there is a fusion reactor in the giant fish!" Mao Zhengzhi lowered his voice to remind Lu Yongchang, "Do you think these giant fish are artificial products?"

"In the depths of the liquid ammonia ocean, maybe there are advanced civilizations living there!"

Lv Yongchang looked at Mao Zhengzhi with the eyes of a fool: "Then why do these giant fish still use such an ancient way of communication?"

"Isn't electromagnetic wave communication good?"

"Is quantum long-distance communication not easy to use?"

Mao Zhengzhi was stunned: "..."

"cough!"

"I, I'm just kidding, liven up the atmosphere..."

Lu Yongchang waved his hands helplessly: "The samples are too small, I guess we have to wait for the next exploration..."

"professor."

"The [Poseidon] exploration ship has a little abnormal situation."

The moment the voice sounded, Zero's avatar appeared beside Lu Yongchang: "After a comprehensive evaluation, I think you should be interested in this abnormal situation."

"【Poseidon】?"

Lu Yongchang subconsciously frowned.

A few days passed, and if it wasn't for Zero's words, he would have almost forgotten about this abandoned exploration ship—although the various sensors inside it are still working hard to provide humans with various data.

"Has that giant fish not given up yet?" Mao Zhengzhi sighed, "It's stubborn enough, I really don't know why it did this..."

Lu Yongchang didn't speak, but nodded towards Ling's avatar.

The next moment, Zero's virtual image turned into light particles and dissipated in the air, and a holographic projection appeared at the same position.

"After being hit for a long time, [Poseidon] only the main searchlight and the main camera are still working normally." Zero explained softly, "Just 5 minutes ago, under the impact of the giant fish, the armor at the stern of the exploration ship broke down. Minor damage."

Lu Yongchang frowned: "So, what is the abnormal situation you are talking about?"

Under Zero's control, the exploration ship turned an angle with difficulty.

The holographic image slowly rotates accordingly.

Under the powerful light of the main searchlight, an astonishing picture appeared in front of the two of them.

The tail of the giant fish, whose body was originally dark brown, was stained with a little silver-white substance.

"This..." A guess flashed in Lu Yongchang's mind, and he stepped forward excitedly, "Is this the armor on the surface of the exploration ship?"

"After comparing all aspects, yes." Ling affirmed Lu Yongchang's guess.

"Understood... I understand!"

Lu Yongchang clapped his hands vigorously: "You are right, that is not something that grows from the giant fish at all!"

"That thing is not skin at all!"

"We've all been misled!"

Mao Zhengzhi naturally understood the meaning of Lu Yongchang's words.

At this moment, he was also a little excited.

On the one hand, it was because the puzzle that had puzzled them for several days was finally solved.

On the other hand, he sighed sincerely from the bottom of his heart—he didn't have to go to the ice giant to eat giant fish.

"It's just..." After a short period of excitement, a trace of doubt flashed in Lu Yongchang's eyes, "How did it get the armor of the [Exploration Ship] on itself?"

Mao Zhengzhi shrugged: "It may be some kind of mucus secreted from the body."

"Wait and see, maybe it will be demonstrated to us in person soon."

……

As Mao Zhengzhi said.

The stability of the [Exploration Ship] after the armor was damaged has dropped significantly.

After the two collisions, another huge piece of silver-white armor fell off from the hull, and slowly sank to the pitch-black liquid ammonia seabed.

The silver-white armor is full of traces of various scratches and impacts.

It's like the dark brown "armor" on the giant fish.

"zero!"

Looking at the violently shaking and shaking picture in front of him, Lu Yongchang said excitedly: "Immediately adjust the posture of the exploration ship! Keep up with the movement of the giant fish, I want to see what it does!"

The picture gradually stabilized, and the scene in it gradually became clearer.

I saw a streamlined giant fish, after a brief acceleration, slammed the side of its body into the silver-white armor.

It can be clearly seen through the high-precision camera that the body of the giant fish is covered with a layer of transparent mucus at this time.

A dull sound came along the liquid ammonia sea water, and at the same time, the silver-white armor stuck firmly to the side surface of the giant fish.

After confirming that the silver-white armor was attached to the body surface, the giant fish stopped moving, quietly suspended in the liquid ammonia seawater.

The exploration ship gradually approached, and "snap" the camera to the side of the giant fish.

More and more transparent mucus gradually covered the silver-white armor.

Then, under the watchful eyes of Lu Yongchang and Mao Zhengzhi, this layer of flowing mucus gradually solidified.

The silver-white armor, like a layer of skin, was firmly attached to the body surface of the giant fish, just like the dark brown unknown alloy.

The giant fish swung its body and moved again.
