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

Therefore, while Lv Yongchang and the other two explored a different path, Meng Lu also chose another path.

After hundreds of years of immersion in the language field, after observing more than [-] samples, she had a vague guess in her heart.

Perhaps, from the very beginning, their research direction has been deviated.

The study of individual sound clips may not have any meaning for these alien life.

This is also normal, after all, these giant fish are not even carbon-based organisms.

From the root, they are extremely different from humans or earth creatures.

After thinking of this, Meng Lu began to change her mind.

She no longer obsesses over the differences in each sound clip, but divides similar sound clips into the same area.

As for the similarity criteria, it is very simple and crude.

The time is close.

The other billions of details are not important.

With zero help, data processing is not difficult.

In just a few seconds, countless complicated data were arranged and combined according to Meng Lu's thoughts.

She took a few steps back, then raised her head, taking the entire holographic image into her eyes.

Although the various data are still a bit messy, she still found some superficial regularities.

"Zero, mark the frequency changes of these sound clips."

Meng Lu stepped forward quickly, raised her hand excitedly, gestured on the holographic projection, and said in a somewhat hoarse voice.

The picture in the holographic projection changes rapidly.

"So it is... so it is!"

"Our research direction was wrong from the beginning!"

"They don't communicate by ultrasonic waves at all!" Meng Lu's lips trembled slightly, and an unusual blush appeared on her face due to being too excited, "No, that's not accurate..."

"Where's the professor?" She suddenly came back to her senses and shouted, "Zero, tell Professor Lu that I understand! I have cracked the giant fish's language system!!"

Chapter 485 Unusual phonemes and syllables

the other side.

Lu Yongchang and Mao Zhengzhi were concentrating on the holographic projection in front of them.

In the holographic image, there is a picture from the [Glutton] material storage ship in the synchronous orbit of the ice giant.

Under Zero's control, two robots are carefully lifting a special container into a special high-pressure laboratory.

In the container, what is loaded is naturally a skin sample from an amino giant fish.

Although the high-pressure laboratory cannot match the living environment of the liquid ammonia giant fish, it can still simulate the environment of the shallow waters of the liquid ammonia ocean.

After all preparations were completed, the robot opened the special container.

A dark brown skin sample with various impact and scratch marks on its surface is displayed in front of the camera.

Unlike the pictures taken by the exploration ship, under the sufficient light in the laboratory, the skin on the surface of the giant fish even reveals a little metallic luster.

This scene made Lu Yongchang feel a little confused.

"This...doesn't look like a biological tissue?" Mao Zhengzhi on the side expressed Lu Yongchang's heartfelt feelings.

Lu Yongchang nodded slightly, but did not express his opinion, but frowned and said: "Let's observe it with a microscope first."

After the voice fell, Zero immediately controlled the robot to start sampling and observing.

have to say.

The skin on the surface of the giant fish is indeed extremely tough. Although it has not been tested, Lu Yongchang believes that its strength will never be lower than the strongest material currently available to humans.

After waiting for a long time, the microscope observation screen finally appeared in front of Lu Yongchang and Mao Zhengzhi.

"This?!"

"How is it possible?!" Mao Zhengzhi and Lu Yongchang's exclamation sounded in the laboratory.

"This is definitely not a biological tissue!" Mao Zhengzhi said firmly.

"That's right." Lu Yongchang said with a serious expression, "It looks like some kind of metal, no, or some kind of alloy."

Mao Zhengzhi frowned, and muttered to himself, "This...how is it possible?"

"It stands to reason that the basic structure of their bodies should be cells."

Lv Yongchang didn't reply, just silently watching the picture in the holographic projection.

Academician Mao Zhengzhi is right.

Since these giant liquid ammonia fish like cesium chloride and rubidium chloride, they should be organisms with cell structure.

Only amino organisms with a cellular structure require these salts to regulate the potential of the cell membrane.

But the alloy skin in front of him, or the alloy armor, completely shook Lu Yongchang's belief.

Cellular organisms can grow alloy skin?

Do not make jokes!

Reminiscent of the fusion reactor in the belly of the liquid ammonia giant fish, Lu Yongchang couldn't help but have an astonishing guess in his mind.

"Could it be..." Lu Yongchang's lips moved slightly, and he said in an extremely low voice, "These giant fish are man-made?"

Judging from the various clues discovered so far, perhaps only this answer can explain the source of the alloy skin.

"No, that's not right." Lu Yongchang shook his head again and again, rejecting his idea again.

"If the giant fish is a mechanical creature, then why does it feel pain when it is burned by high-temperature ammonia bubbles?"

When the cockpit fled, everyone could see clearly that a giant fish rushed into the ammonia bubble and made a struggling movement.

This is not the reaction of mechanical energy!

One doubt after another emerged in Lu Yongchang's mind.

"Professor, Researcher Meng Lu is looking for you." Ling's voice sounded just right, interrupting the thoughts of Lu Yongchang and Mao Zhengzhi.

"Meng Lu?" Lu Yongchang frowned, subconsciously said, "Let her wait first."

"Professor, she said that she has cracked the language system of the giant fish." Zero reminded again.

"Then let her wait...wait, what did you say?" Lu Yongchang suddenly stopped his right hand that was about to turn off the holographic projection, "She cracked the language system of the giant fish?"

"Yes, Professor."

"Hiss..." Lu Yongchang gasped lightly, turned his head to look at Mao Zhengzhi beside him, and then said in a deep voice, "Zero, test the samples according to the original plan."

"Old Mao, let me go to Meng Lu's side first."

"Damn... how did she find the pattern from this pile of messy codes???"

While complaining, Lu Yongchang sighed to Mao Zhengzhi: "Okay, old Mao, where did you find this talent..."

Facing Lu Yongchang's exclamation, Mao Zhengzhi shrugged.

"A post I saw on the Academy of Sciences forum some time ago."

"From what the researchers said, that researcher Meng Lu should be the most knowledgeable ancient language scholar in the People's Federation."

Lu Yongchang: "..."

……

As soon as he walked into Meng Lu's laboratory, Lu Yongchang was shocked by the huge holographic projection in front of him.

In the projection, more than 1000 minutes of sound wave spectrum is organized into hundreds of blocks, and more than [-] ultrasonic segments are summarized in each block.

With just one glance, Lu Yongchang discovered the principle of classification.

"The duration is similar?"

Meng Lu, who was sorting out before the holographic projection, hurriedly turned around.

Seeing Lu Yongchang and Mao Zhengzhi, Meng Lu subconsciously turned around to greet her: "Professor Lu, Academician Mao..."

"Don't talk nonsense, let's start directly." Lu Yongchang waved his hand, interrupting those insignificant etiquette, "Why do you have to classify by time?"

"There seems to be no similarity between the ultrasonic fragments in these categories, right?"

Meng Lu straightened her expression, nodded and said, "Yes, there is really no similarity between the ultrasound clips alone."

"However, we fell into a misunderstanding."

"The communication of these giant fish is not like us, relying on pure syllable communication."

Hearing this, Lu Yongchang was slightly taken aback: "Do you not rely on syllables to communicate?"

"To put it simply, their shouts really don't make any sense." Meng Lu shrugged. "In a sense, they have been shouting nonsense."

Mao Zhengzhi's face changed slightly, and he immediately retorted: "This is impossible. According to our observations, these giant fish must rely on ultrasonic waves to communicate!"

"Academician Mao, please listen to me first." When it came to her major, Meng Lu's aura instantly became stronger, "Indeed, they rely on ultrasonic waves to communicate."

"But ultrasound is just a vehicle."

"The real information is hidden in the rapidly changing frequencies of these ultrasonic waves!"

"Zero, switch images."

The holographic projection screen changes instantly.

"Professor, this is a graph of ultrasonic frequency changes for each similar period of time." Meng Lu pointed to the undulating curve in the holographic projection, "It seems very messy, but if we do a simple processing of it... ..."

While speaking, Meng Lu waved her right hand: "The sampling interval is 0.1 second, and then all samples will be compared..."

The curves in the holographic image are quickly disassembled into countless small fragments.

With the help of Zero's powerful computing power, these small fragments move rapidly, and the same fragments overlap each other, eventually forming 52 different fragments.

"Then, we can find that these ultrasonic fragments all have the same frequency change band!"

"And these frequency-changing bands can even be found in all sound samples."

"As of now, I have found a total of 52 frequency-changing bands."

"From this, I made a judgment."

"These 52 frequency bands are the unique phonemes in their language."

Chapter 486 Communication Like Music

"Phoneme?" Mao Zhengzhi muttered to himself, frowning slightly.

Seeing the puzzled look on Mao Zhengzhi's face, Meng Lu hurriedly explained.

"A phoneme is the smallest unit of speech that is divided according to the natural properties of speech."

"Like vowels and consonants, for example, the Chinese language we currently use has a total of 32 phonemes."

"All our usual communication is done by relying on these 32 phonemes."

"As for the communication between these giant fish, I have discovered 52 phonemes so far. Although there may be other phonemes that have not been discovered yet, with these 52 phonemes, it should be possible to do a simple analysis of their language system. "

Lu Yongchang and Mao Zhengzhi nodded again and again.

Worthy of being professional.

Lu Yongchang once again turned his gaze to the holographic image aside, carefully observing all the processed voice clips.

"what?"

His eyes moved slightly, as if he had noticed something.

Under the watchful eyes of Meng Lu and Mao Zhengzhi, Lu Yongchang stepped forward and stretched out his hand to delineate an area in the holographic projection.

"Professor?" Meng Lu looked at Lu Yongchang's actions in surprise, and was puzzled for a while.

Lu Yongchang did not speak, but processed the delineated audio clips on his own.

With the help of Zero, Lu Yongchang easily removed various frequency fluctuations that contained information.

Afterwards, a spectrum graph that was relatively stable but still fluctuated slightly randomly appeared in front of everyone.

"This is..." Mao Zhengzhi was stunned. As a biologist, he had already sensed the significance of Lu Yongchang's actions. "No wonder we couldn't find any similarities at that time!"
