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

He didn't see the so-called light source in it.

"Wait, where's the light source?"

"Professor, the light source is gone!"

"Hancent, is the sonar turned on?"

Hansen's voice sounded: "It's open, it's already open!"

Hope continued: "Professor, we have activated the active detection sonar..."

"...Damn it!!"

"What the hell is this?!"

There was a chaotic sound on the communication channel.

The uneasiness in Lu Yongchang's heart became more and more intense. He didn't have time to ask Hope, but directly issued an order to Zero: "Zero! Call out the sonar data!"

Looking at the huge, rock-like streamlined gray shadow under the exploration ship in the holographic projection, all the scientific researchers present swallowed subconsciously.

"A reef?" Hope raised his voice, "Professor, is this a reef?"

"..." Looking at the gray shadow, Lu Yongchang struggled to squeeze out a sentence.

"Obviously, there would be no reefs in the ammonia oceans of ice giants."

Chapter 475 Professor, are you sure it won't attack us?

"At least, at your depth, there should be no reefs or anything like that..."

Lu Yongchang spoke again and added.

But obviously, no one cared about this sentence.

Especially when I saw that huge gray shadow began to move slowly in a circular motion around 【Poseidon】.

"Professor...you mean, this thing is alive?!" Hope's face changed drastically, and he asked with shortness of breath.

"At present, it should be." Lu Yongchang swallowed, looked at the slow-moving gray shadow in the sonar image, and explained in a hurried tone, "According to our research, the turbid objects in the sea should be Organics like peptides and amino acids."

"This creature... let's treat it as a creature, if it is made of these polypeptide-like and amino acid-like substances, then..."

"It should belong to Aminobiology."

During the speech, the gray shadow seemed to be stimulated by something, and the speed of movement began to increase slowly.

In the sonar image, the distance between the unknown creature and the [Poseidon] exploration ship fluctuates.

In the camera, the flickering orange light was also captured.

However, unlike Hope's report, the orange-red light flickers at a higher frequency at this time, and a flicker will occur in about 8 seconds.

"Is it curious?"

Mao Zhengzhi's doubtful voice sounded from the side, "Or... are you testing?"

Lu Yongchang's expression froze slightly.

Indeed, as Mao Zhengzhi said, the actions of this deep-sea giant at this time were somewhat tentative.

"Professor, what should we do now?!" Facing the temptation of the unknown giant creature, Hope couldn't help feeling his scalp tingling, "Surfacing?"

"do not move!"

Before Lu Yongchang could speak, Mao Zhengzhi on the side shouted loudly: "Don't move around! Keep hovering!"

"Turn off the sonar device first."

"If I'm not wrong, it should be attracted by the sonar equipment that was turned on during the dive!"

Hope and Hansent looked at each other, without any hesitation, they directly turned off the running sonar device.

As Mao Zhengzhi said, during the dive, the sonar equipment for active detection was always working, and the sonar detection device was not turned off until the exploration ship hovered in place to perform seawater sampling tasks.

It was also at this time that this unknown creature came out from deeper in the ocean.

[Poseidon], who turned off the sonar equipment, became completely blind in this vast ocean of liquid ammonia.

But the next moment, a 3D simulation image appeared in front of everyone.

In the simulation picture, the central area is the [Poseidon] exploration ship with a diameter of less than [-] meters, and beside the exploration ship, there is a huge creature with a streamlined body and a length of more than [-] meters circling rapidly swim.

"This is..." Hope was stunned, and subconsciously asked.

"Combined with the sonar data just now, Zero made a simulated image based on the orange light captured by the camera." Lu Yongchang simply explained, "The observation data is not enough, and the simulated image may be slightly different from the real situation."

Hope and Hansen looked a little more relaxed.

Although it is not as good as sonar, it is better to have analog images than nothing.

"It slowed down."

Mao Zhengzhi's voice suddenly sounded.

After hearing this, Hope quickly turned his attention to the simulated image provided by Zero.

Sure enough, after turning off the sonar, the wandering movements of the huge deep-sea creature slowed down a lot.

"Sure enough..." Mao Zhengzhi stared intently at the holographic projection, and muttered to himself, "Living in such a deep sea, these liquid ammonia creatures will inevitably evolve a matching perception method."

"You mean...ultrasound?" Lu Yongchang frowned and asked softly.

Mao Zhengzhi nodded slightly.

"The sea of ​​ice giants is pitch black. To grow in this year-round dim environment, vision should be the last function they need."

"But sensing the outside world is an ability that organisms must possess."

"When you think of something like a bat, it's not that hard to come to that conclusion."

Lu Yongchang didn't speak immediately, but silently watched the huge creature slowly circling the [Poseidon] exploration ship in the simulated image.

Suddenly, he asked.

"What about the orange light?"

"How to explain that thing?"

Mao Zhengzhi was taken aback for a moment, then frowned.

He understood the meaning of Lu Yongchang's words.

Naturally evolved organisms generally do not have useless functions on their bodies.

Like the deep-sea anglerfish of the Earth era, it has a fleshy protrusion resembling a small lantern above its head.

Under the action of luciferase, this fleshy protrusion, which resembles a small lantern, emits a faint light.

Most fishes living in the deep sea have a certain degree of phototaxis.

Therefore, this luminous "little lantern" has become a sharp weapon for anglerfish to hunt.

If you compare it to this deep-sea behemoth that lives in an ocean of liquid ammonia, the problem arises.

If these amino organisms don't have so-called vision, or in other words, they don't have phototaxis, then what is the flickering light emitting from them for?

You can't just evolve a boling boling and twinkling decorations on your body for the sake of looking good, right?

"hiss……"

Mao Zhengzhi put his hand on his chin, lost in thought.

"Teach...professor..."

"Can you stop discussing such a profound question?"

"Think about what we should do first!!"

Hansent's trembling shout came from the loudspeaker, interrupting Lu Yongchang and Mao Zhengzhi's thinking.

Facing this unknown deep-sea giant, the fear engraved in human DNA broke out completely.

Especially looking at the orange light floating by outside the porthole, and then thinking of the terrifying environment outside and the giant deep-sea monster with a body length of more than two hundred meters, deep fear suddenly rose in the hearts of the two of them!

Even though Hope and Hansent are starship pilots who have undergone various trainings, at this moment, they have come to the brink of collapse.

"cough……"

Lu Yongchang coughed in embarrassment.

Facing amino creatures that had never been seen before, both he and Mao Zhengzhi forgot the current situation for a moment.

"How about trying to float up?"

Lu Yongchang looked at Mao Zhengzhi and made a suggestion: "Without turning on the sonar, see its reaction."

Mao Zhengzhi pondered for a moment, then nodded hesitantly.

"Okay, but... the ascent speed should be as slow as possible."

"At present, we know too little about it, and it cannot be ruled out that it has a strong desire to attack."

Lu Yongchang understood: "Have you heard everything?"

"Try to float first, and slow down as much as possible."

"...Try, try?" There was even a bit of crying in Hansent's voice, "Professor, are you sure it won't attack us?"

"……uncertain."

As an honest person, Lu Yongchang naturally replied honestly.

Chapter 476 Attack?play?

"..."

"???"

"professor?!"

Hearing Lu Yongchang's words, Hope couldn't hold back anymore, and asked, "Can [Poseidon] resist its attack?"

"This is not sure."

Lu Yongchang replied honestly again.

"..."

long silence.

"Calm down, calm down." Lu Yongchang said with a smile in his eyes, "I'm kidding you."

"Seeing that the atmosphere on your side is too stiff, I will give you an active atmosphere."

In the long-distance communication, there is still a long silence.

Hope: You call this an active atmosphere?

After waiting for a long time, he asked again: "So, you mean it won't attack us?"

"Oh, I'm really not sure about this." Lu Yongchang shrugged and said again.

"After all, it is a species that has never been seen before, and we don't know its eating habits, let alone its desire to attack."

"It can only be said that at present, after turning off the sonar, its movements have become much smoother."

Hearing this, Hope and Hansen almost didn't bring it up: "..."

Hansen: You call this an honest man?

"However, it is just a creature after all." Lu Yongchang said with a smile, "I don't think it can damage our exploration ship."

"Float with peace of mind."

Hope breathed a sigh of relief.

Finally heard a correct sentence.

He stopped talking, and raised his hand to adjust various parameters on the holographic projection.

After the adjustment, he started the [Poseidon] exploration ship without hesitation.

A very slight recoil came from the back of the chair.

The survey ship began to float up.

In the simulated image provided by Zero, the liquid ammonia creature still stayed in place, spinning slowly, as if watching them leave.
