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

Meng Lu stared at the translation in the translation device, her eyes slightly widened.

"Quick! Follow it!!"

At the same time, in the sonar chart, the distance between the giant fish and the exploration ship is rapidly increasing.

"It's diving!" Hope moved his eyes slightly, without any hesitation, he directly activated the water jet propulsion device.

"Hancent, follow its ultrasonic signal!"

"Whether our mission can be completed depends on this wave!"

Chapter 492 Breaking into the interior, a simple biosphere

In the dark sea of ​​liquid ammonia, a giant fish about 200 meters in length kept swinging its powerful body, continuously drilling towards the depths of the sea of ​​liquid ammonia.

A silver-white survey ship with incandescent searchlights was struggling to follow behind it.

From time to time, the giant fish in front would slow down its dive speed, hovering in place and waiting for the exploration ship to catch up with its "footsteps".

What a harmonious picture.

If you ignore the dense and disgusting words in the translation device.

"did not expect……"

Hopson leaned unlovingly on the chair behind him, staring blankly at the looming orange-red halo outside the porthole: "Are these giant fish still talkative?"

But when you think about it, it's understandable.

Living in such a vast ocean of liquid ammonia, maybe only talking to yourself can relieve the loneliness in your heart?

Thinking of this, Hope couldn't help feeling a little sympathy.

……

The dive time is extremely long.

As the depth increases, the pressure around the exploration ship increases sharply, and the temperature of the liquid ammonia seawater also rises a lot compared to the beginning.

Like Neptune, this ice giant planet also has its own heat source inside.

"The Kelvin-Helmholtz principle." Looking at the gradually rising thermometer reading, Hope said to himself, "When the surface of a star or planet cools down, it causes the pressure drop of the star and planet, and finally this pressure drop Compensate in the form of shrinkage."

"In the process of contraction, the potential energy of matter falling inward is converted into heat energy, which heats the core of a star or a planet in disguise."

"Usually happens on gas giants, ice giants, or brown dwarfs."

Hansen: "..."

My head is so itchy, I feel like I'm going to grow my brain.

"A large number of unknown objects have been detected."

The electronically synthesized voice interrupted the "discussion" of the two.

Hansen subconsciously looked up at the porthole.

"...Damn it!!"*2

The soul-stirring national quintessence once again echoed in the small cockpit of the exploration ship.

Outside the porthole, at a glance, there are at least dozens of orange-red rings swimming slowly in the pitch-black liquid ammonia ocean.

Hope was short of breath, trembling slightly, and stammered, "Teacher, professor... I, we..."

"It seems to have broken into the opponent's lair..."

Lv Yongchang, who was far away on Dawn Star, looked at the picture sent by the camera, and he was a little bit impatient.

"Don't, don't panic!"

He took a deep breath, calmed himself down and said in a deep voice: "Theoretically, they can't find you."

"Follow the leader of the giant fish with peace of mind, and try to find the ore vein."

"Theory again..." Hope and Hansen swallowed hard, "Professor, are you sure we can escape from the cockpit?"

"Theoretically..." Lu Yongchang's voice suddenly paused, and then fell silent for a moment.

"Don't worry, I will definitely be able to escape!"

"Okay, okay..."

Hope rubbed his palms together, and held the control lever of the exploration ship with slightly trembling hands.

A "water stream" jetted out from the stern of the exploration ship, pushing the exploration ship forward slowly.

For the arrival of the "newcomers", these giant fish showed extremely strong curiosity.

In just a few tens of seconds, more than a dozen giant fish, large or small, appeared near the exploration ship.

In order to avoid collisions, the forward speed of the exploration ship has also been repeatedly reduced.

The leader of the giant fish leading the way obviously noticed this scene.

It turned around, quickly returned to the exploration ship, opened its big mouth, and emitted waves of strong ultrasonic waves.

After a few seconds.

The giant fish watching the excitement around the exploration ship retreated a certain distance silently, giving way to the way forward.

The leader of the giant fish "glanced" at the exploration ship, swung his body again, and swam forward.

Hope wiped the cold sweat off his forehead with his hand, and complained softly: "How do you feel that it looks a little complacent?"

Hansent also nodded in agreement: "It's kind of like showing us what you can do, typical animal courtship behavior."

After finishing speaking, Hansent's face suddenly turned ugly.

Animal courtship behavior is not scary.

But if the object of courtship is yourself, it will be terrible.

Especially when the opponent is a giant aminofish with a body length of 200 meters!

Without the interference of the giant fish, the exploration ship followed behind the leader of the giant fish and slowly swam forward.

"The water is getting murkier."

Looking at the picture in the camera, Hope said in a deep voice.

Before Hansen could speak, a "slender" shadow flashed across the screen.

……

"what is that?!"

Lu Yongchang, who was on Dawn Star, naturally also saw this scene, and he immediately shouted: "Zero! Play back the picture!"

After a short wait, a clear image appeared in front of everyone.

"biology?"

Lu Yongchang looked at the picture in the holographic projection, and said in a daze: "In this ocean of liquid ammonia, is there a biosphere that belongs to you alone?!"

"I'm afraid so."

Mao Zhengzhi looked at the pictures sent by the camera, and whispered softly: "These creatures should be similar to the krill in the earth's oceans, but their size is larger than that of krill."

"If nothing else, they should be one of the food sources for these giant fish."

"How do you know?" Lu Yongchang asked subconsciously.

Mao Zhengzhi didn't speak, but just pointed to a holographic picture.

In the picture, under the illumination of the main searchlight, a large group of krill-like creatures wanders in the turbid liquid ammonia seawater.

The next moment, the leader of the giant fish opened its mouth wide, swallowing the sea water and swallowing all these krill-like creatures into its stomach.

"If my guess is correct..." Mao Zhengzhi muttered to himself, "these krill-like organisms should have abundant deuterium-tritium resources."

"They could feed the giant fish's fusion reactor."

……

The depth continues to descend.

In addition to krill-like creatures, some strange-looking creatures appeared around the exploration ship.

In the warm liquid ammonia sea water, they swim freely.

"Unbelievable..." Mao Zhengzhi's voice came from the speaker, "There is actually a simple biosphere deep in the ice giant!"

Yes, a simple biosphere.

So far, they have only found more than a dozen species of organisms.

Among the more than ten species of creatures, except for the giant fish, the rest are all within one meter in size.

According to current observations, the giant fish is the well-deserved overlord in this liquid ammonia ocean!

As the depth continued to increase, the temperature of the liquid ammonia seawater also continued to rise, and the surrounding organisms gradually decreased until they disappeared.

"This place is no longer a livable zone." Mao Zhengzhi nodded thoughtfully. "It seems that except for the giant fish, the range of activities of these small creatures is still very small."

Chapter 493 Star Gold Vein

"Following the target has stopped diving."

"A large range of unknown objects has been detected ahead."

The electro-synthesized sound came through just right, grabbing everyone's attention.

The water jet propulsion device began to run in reverse, and the forward speed of the survey ship also decreased rapidly.

Hope frowned and looked at the porthole directly ahead.

Outside the porthole, under the illumination of the main searchlight, a thick "wall" appeared in front of him.

The "wall" is pyramid-shaped, standing quietly in the dark and deep liquid ammonia ocean.

Under the illumination of the searchlight, it glowed with a dark brown metallic luster, basically the same color as the armor on the giant fish.

"This is..." Hope murmured in a low voice, "Star gold veins?"

Xingjin is the name given by the Academy of Sciences to this recently discovered alloy.

The origin of the name is also very simple.

The alloy born inside the ice giant is star gold.

Looking at some scratches and impact marks on the top of the "wall", Hope can even imagine in his mind the scene that once happened here - giant fish exhausted their whole body and kept hitting this huge "wall". ", and "weave" the fallen debris into armor, and "wear" it on itself.

only……

Do those newly born giant fish also have the power to shake this huge star gold vein?

If this is the case, how strong should the physical fitness of these giant fish be? !

Hope suppressed the doubts in his heart, and turned to look at the holographic projection aside.

Over there, there are high-definition images captured by the camera.

The camera moves down slowly, and the direction of the searchlight also moves down.

The dark brown "wall" gradually widened and thickened until it became a huge shadow hidden in the endless ocean of liquid ammonia.

"This is simply..." Hansen sighed from the side, "It's a large mountain range!"

Looking at the huge pyramid-shaped mineral veins slowly drawn by the sonar device, Hope nodded excitedly.

"Get rich!"

"This vein is enough to meet the current needs of human beings!"

After a brief moment of stupefaction, Hansen also reacted: "Fuck?! How many contribution points and credit points does this have to be converted into?!"

"Get rich, get rich..."

"Ahem!" Perhaps hearing the exchange between the two, Lu Yongchang coughed lightly, "Remind you two, this exploration mission..."

"There shouldn't be many credit rewards."

Hansen: "..."

Hope: "..."

Bad, almost forgot about this.
