Just like my previous experience entering the Ice Giant, this journey was also thrilling but ultimately safe.

After passing through ammonia ice clouds and thunderstorm layers, the Poseidon II exploration vessel, accompanied by a light drizzle of liquid ammonia, plunged into the boundless ocean of liquid ammonia.

Unlike the first-generation Poseidon exploration vessel, the second-generation exploration vessel eliminated the original propeller propulsion device in order to avoid arousing the "displeasure" of the giant fish, and instead used a water jet propulsion device.

Compared to a propeller, its propulsion efficiency is much lower, but it is quieter.

Under the searchlights, the dark sea was completely still, seemingly devoid of any life.

But Hope and Hansent, having experienced their last life-or-death crisis, were naturally not fooled by appearances.

They silently activated the active sonar system and steered the exploration vessel toward the ocean of liquid ammonia.

Similarly, in order not to offend the giant fish, the active sonar devices were also modified to some extent—they used the same reference frequency as the giant fish to probe the surrounding environment.

...

"From the giant fish's 'perspective,' this exploration vessel might be one of their own kind that cannot speak."

The day before departure, Lü Yongchang told the truth.

"Therefore, based on our speculation, these curious giant fish might travel a long way to come when they hear this frequency."

"The purpose... is naturally to watch the excitement."

“In their world, it would be very difficult to find such an ‘oddity’.”

Upon hearing Lü Yongchang's words, Hope and Hansent's expressions changed.

This is even worse than the first-generation exploration vessel!

"Calm down, calm down." Noticing Hope and Hansent's expressions, Lü Yongchang immediately smiled and reassured them, "Isn't there still an ultrasonic generator?"

"Once activated, it can transmit ultrasonic signals of various frequencies to the outside world."

"These signals can convey simple meanings to the giant fish, such as... do not approach, warnings, etc."

"Theoretically speaking, you should be able to disguise yourselves as their kind."

"Theoretically speaking?" Hope's lips twitched slightly as he repeated in a low voice.

"Ahem!" Lü Yongchang coughed lightly. "There's nothing we can do about it."

"After all, we don't have any experimental subjects, so everything can only be inferred from the existing data."

"But don't worry."

"Like the first-generation exploration vessel, the second-generation exploration vessel is also equipped with a cockpit ejection function."

"In case of an accident, the ultrasonic generator can act as a decoy to buy you precious time to escape."

Seeing the stiff expressions on Hope and Hansent's faces, Lü Yongchang could only offer an explanation from a different angle.

"Think about it from a different perspective."

"This will greatly help you complete your exploration mission."

"How can we find the mineral resources hidden in the deep sea without infiltrating the enemy's territory?"

"You agree, right?"

Seeing Lü Yongchang's expression, Hope and Hansent could only nod stiffly.

...

The Poseidon II exploration vessel slowly descends into the dark ocean of liquid ammonia.

Inside the cockpit.

Hope and Hansent were using the small game console to pass the time.

Do you even know how to play?

"Here you go! Even my grandma could play better than you!"

Faced with Hansent's relentless taunts and looking at the gray holographic interface, Hope had no choice but to relinquish control of the game console.

"Beep! Beep! Beep!"

"Unidentified object detected!" Zero's synthesized voice rang out at that moment, "Preliminary assessment: Amino Giant Fish."

At the same time, the sonar image above the console automatically zooms in.

A streamlined silhouette, highlighted in red, is slowly circling the exploration vessel.

"They're here!"

Hope's expression immediately turned serious, and he reached out and patted Hansent beside him: "Stop playing around, it's time to get down to business!"

...

Outside the exploration vessel, in the pitch-black ocean of liquid ammonia.

A massive ammonia fish is circling endlessly.

Its actions revealed that it was quite puzzled at the moment.

Waves of ultrasound, signaling inquiries, emanated from its mouth and propagated toward the exploration vessel.

...

"What do these ultrasound waves mean..."

Hope reached out and opened the translation program next to her.

The comparison results appeared quickly in the holographic projection.

“It’s expressing confusion.” Hope’s eyes lit up slightly. “Professor Lu wasn’t wrong after all; it might really be mistaking us for one of its own kind!”

“The kind that can’t speak,” Hope added again.

Before Hansent could speak, Zero's synthesized voice rang out again.

"Connection request in progress..."

The next second, a familiar voice came from the speaker.

"As planned, we are about to begin the first exchange."

Without any preamble, Lü Yongchang got straight to the point.

"receive."

...

Hope carefully selected a few keywords for greetings and fed them into the ultrasonic generator.

start up.

An ultrasonic wave, inaudible to the human ear, spread outwards along the seawater.

A few seconds later, a response appeared.

"It's expressing joy." Hansent looked excitedly at the Chinese characters appearing in the holographic image. "It's joy at encountering its own kind!"

Hope stared blankly at the holographic image in front of her, a deep sense of joy slowly seeping from her bones.

This was his first time communicating with extraterrestrial beings!

As the text kept appearing in the holographic image, Hope took a deep breath and suppressed the pounding in her heart: "Continue to respond."

"Like it, we also express joy."

Hansent nodded repeatedly and quickly selected a few keywords.

send.

A few seconds passed in the blink of an eye.

The exploration vessel did not receive the other party's ultrasonic waves.

"What's going on... is there a problem with the information?" Hope looked puzzled, glancing down at the holographic projection again. "It's fine, these are all keywords indicating joy..."

"warn!"

The piercing alarm shattered the tranquility of the cockpit: "The enemy is rapidly approaching!"

"Impact warning!"

Hope's face changed drastically: "Holy crap! Professor! The translation program is malfunctioning!!"

The reason for this anomaly is obvious to Hope, even to his own toes.

What else could it be but a translation program error?!

On the other side, Lü Yongchang's lips twitched slightly as he turned his head to look at Meng Lu beside him.

Meng Lu: "..."

...

"Beep!! Beep! Beep..."

The urgent alarm gradually subsided.

Hope relaxed her tense body and slowly opened her eyes to look at the camera screen.

An orange-red ring of light was quietly positioned directly in front of the exploration vessel.

"Han...Hancent, turn on the main searchlight..."

Hope swallowed hard and began to speak with difficulty.

The next second.

The beam of the main searchlight pierced through the slightly murky liquid ammonia seawater and shone directly onto the giant fish.
