Age of Cataclysm: I can light up the technology tree

On the other side.

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

The holographic image showed a picture from the [Taotie] material storage ship located in the synchronous orbit of the ice giant.

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

The container was naturally loaded with skin samples from the amino giant fish.

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

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

A dark brown skin sample with various impact and scratch marks on the surface was exposed 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 showed a little metallic luster.

This scene made Lv Yongchang a little confused.

"This... doesn't look like biological tissue?" Mao Zhengzhi, who was standing aside, expressed Lv Yongchang's thoughts.

Lv Yongchang nodded gently, but did not express his opinion. Instead, he frowned and said, "Let's observe it with a microscope first."

As soon as the voice fell, Zero immediately controlled the robot to start sampling and observation.

I have to say.

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

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

"This?!"

"How is it possible?!" The exclamations of Mao Zhengzhi and Lv Yongchang sounded in the laboratory.

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

"Yes." Lv Yongchang looked solemn and said in an affirmative tone, "It looks like some kind of metal, no, or some kind of alloy."

Mao Zhengzhi frowned and muttered to himself, "How is this possible?"

"Logically speaking, the basic structure of their body should be cells."

Lv Yongchang did not reply, but just silently watched the picture in the holographic projection.

Academician Mao Zhengzhi was right.

Since these liquid ammonia giant fish like cesium chloride and rubidium chloride, then they should be cell-structured organisms.

Only cell-structured amino organisms need these salts to regulate the potential of the cell membrane.

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

Can cell organisms grow alloy skin?

Don't be kidding!

Thinking of the fusion reactor in the belly of the liquid ammonia giant fish, Lv Yongchang couldn't help but have an amazing guess in his mind.

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

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

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

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

When the cockpit escaped, everyone saw clearly that a giant fish rushed into the ammonia bubble and struggled.

This is not a mechanical reaction!

One after another, doubts emerged in Lv Yongchang's mind.

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

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

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

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

"Yes, professor."

"Hiss..." Lv Yongchang took a breath of cold air, turned his head and glanced at Mao Zhengzhi beside him, and said in a deep voice, "Zero, test the samples as planned."

"Old Mao, come with me to Meng Lu first."

"What the hell... How did she find the pattern from this pile of garbled code???"

While complaining, Lv Yongchang sighed at Mao Zhengzhi: "Great, Old Mao, where did you find this talent..."

Facing Lv Yongchang's sigh, Mao Zhengzhi shrugged.

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

"I heard from those researchers that the researcher Meng Lu should be the most knowledgeable ancient language scholar in the Human Union."

Lv Yongchang: "..."

...

As soon as he entered the laboratory where Meng Lu was, Lv Yongchang was shocked by the huge holographic projection in front of him.

In the projection, more than 100,000 sound wave spectra were sorted into hundreds of blocks, and each block contained more than 1,000 ultrasonic segments.

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

"Similar duration?"

Meng Lu, who was originally sorting and summarizing in front of the holographic projection, hurriedly turned back.

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

"No need to talk nonsense, let's get started." Lv Yongchang waved his hand, interrupting those insignificant etiquette, "Why do we have to classify by duration?"

"The ultrasonic segments in these categories don't seem to have similarities, right?"

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

"But we've fallen into a misunderstanding."

"The communication of these giant fish is not like ours, which relies on simple syllable communication."

Hearing this, Lu Yongchang was slightly startled: "Don't communicate by syllables?"

"To put it simply, their shouts really have no meaning." Meng Lu shrugged, "In a sense, they have indeed been shouting blindly."

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 complete communication!"

"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 carrier."

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

"Zero, switch image."

The holographic projection screen changes instantly.

"Look, Professor, this is the ultrasonic frequency change curve for each period of similar duration." Meng Lu pointed at the undulating curve in the holographic projection, "It seems very messy, but if we do a simple process on it... …”

As she spoke, Meng Lu waved her right hand: "The sampling interval is 0.1 seconds, and then all samples are compared..."

The curves in the holographic image were quickly dismantled into countless small fragments.

With the help of Zero's powerful computing power, these small fragments moved quickly, and the same fragments overlapped each other, eventually forming 52 different fragments.

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

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

"So far, I have discovered a total of 52 frequency change bands."

"From this, I made a judgment."

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