Just like the previous experience of joining the ice superstar, this journey was also full of dangers.

After crossing the ammonia ice clouds and thunderstorm layers, the [Poseidon Type 2] exploration ship rushed into the boundless ocean of liquid ammonia accompanied by drizzling liquid ammonia rain.

Unlike the first generation of [Poseidon] exploration ship, in order not to arouse the "disgusting" of giant fish, the second generation of exploration ships canceled the original propeller propulsion device and switched to water-jet propulsion device.

Compared with propellers, although the propulsion efficiency is much lower, it is better to be quiet.

Under the searchlight, the dark and quiet sea water was quiet, and there seemed to be no life in it.

But Hope and Hansent, who experienced the last life-and-death crisis, naturally would not be deceived by this appearance.

They silently turned on the active sonar device and operated the exploration ship toward the liquid ammonia ocean.

Similarly, in order not to cause "disgust" among giant fish, the active sonar device has also been improved - they use the same reference frequency as giant fish to detect the surrounding environment.

...

"To the giant fish 'look', this exploration ship may be a kind of person who can't speak."

The day before departure, Lu Yongchang said truthfully.

"So, according to our guess, these curious giant fish may come far away when they hear this frequency."

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

"It should be difficult to have such a 'weird' in their world."

At that time, when he heard Lu Yongchang's words, Hope and Hansent's faces changed.

This is not as good as the first generation of exploration ships!

"Calm, calm." Lu Yongchang noticed the expressions of Hope and Hansent, and immediately smiled and comforted, "Isn't there an ultrasonic generator?"

"After starting, it can transmit ultrasonic signals of various frequencies to the outside world."

"These signals can convey simple meanings to the giant fish, such as... don't get close, warning, etc."

"In theory, you should be able to disguise yourself as their kind."

"Theoretical?" Hope's mouth twitched slightly and he repeated in a low voice.

"Cough!" Lu Yongchang coughed gently, "This is nothing to do."

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

"But don't worry."

"Like the first generation of exploration ships, the second generation of exploration ships is also equipped with cockpit pop-up function."

"Once an accident occurs, the ultrasonic generator can act as a bait to buy you valuable escape time."

Looking at the stiff expressions on Hope and Hansent's faces, Lu Yongchang could only explain from a different angle.

"Think in a different direction."

"This will be of great help to you to complete your exploration mission."

"How can we find mineral resources hidden in the deep sea without breaking into the enemy?"

"You guys say, right?"

Looking at Lu Yongchang's expression, Hope and Hansent could only nod their heads with stiff expressions.

...

[Poseidon Type 2] The exploration ship slowly dives in the dark water of liquid ammonia.

Inside the cockpit.

Hope and Hansent are using the small gaming console to relieve boredom.

"Can you play?"

"Take it, if you do it, my grandma will be better than you when she comes!"

Faced with Hansent's continuous ridicule and looking at the gray holographic interface, Hope could only helplessly give up the control of the game console.

"Drip!Drip!Drip!"

"Unknown object was detected!" Zero's electron synthesis sounded at this moment, "It was initially judged as an amino giant fish."

At the same time, the sonar image above the console is automatically enlarged.

A streamlined outline marked red is slowly circling around the exploration ship.

"Here you come!"

Hope's expression suddenly became serious and reached out to pat Hansenter beside him: "Stop playing, it's time to do serious things!"

...

Outside the exploration ship, in the dark ocean of liquid ammonia.

A huge amino giant fish was constantly circling.

It can be seen from its actions that it is very confused at this time.

Ultrasound waves indicating inquiries came out of its mouth and spread towards the exploration ship.

...

"What do these ultrasounds mean..."

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

In the holographic projection, comparison results soon appeared.

"It is expressing confusion." Hope's eyes lit up slightly, "Professor Lu didn't say anything nonsense. It may really treat us as similar!"

"The kind who can't speak." Hope added again.

Before Hansent could speak, Zero's electronic synthesizing sound rang again.

"Communication request connection..."

The next second, familiar sound came from the speakers.

“As planned, prepare to start the first exchange.”

Without any nonsense, Lu Yongchang spoke directly.

"receive."

...

Hope carefully selected several greeting keywords and introduced them into the ultrasonic generator.

start up.

A burst of ultrasound that could not be heard by human ears spread along the sea water to the surroundings.

A few seconds later, the response appeared.

"It is expressing joy." Hansent looked at the Chinese characters appearing in the holographic image with excitement. "It is feeling joyful for meeting the same kind!"

Hope stared at the holographic image in front of him, and a sense of joy from the heart slowly oozed out of his bones.

This is his first time communicating with alien creatures!

Looking at the words that kept popping up in the holographic images, Hope took a deep breath and suppressed the throbbing in his heart: "Continue to respond."

“As with it, we express joy.”

Hansent nodded repeatedly and quickly selected several keywords.

send.

A few seconds passed in a flash.

The exploration ship did not receive ultrasound from the other party.

"What's the situation... the information is wrong?" Hope's eyes showed some confusion, and he lowered his head and checked the holographic projection in front of him. "No problem, these are the keywords that express joy..."

"warn!"

The harsh alarm broke the tranquility of the cockpit: "The other party is approaching quickly!"

"Impact warning!"

Hope's face changed drastically: "Damn it! Professor! There's something wrong with the translation program!!"

Hope can come up with the answer to the cause of this abnormal phenomenon with his toes.

What else can be done except for the translation program error?!

On the other side, Lu Yongchang twitched his mouth slightly, turned his head and turned his eyes to Meng Lu beside him.

Meng Lu: “…”

...

"Drip!!Drip!Drip..."

The rapid alarm gradually eased.

Hope relaxed his tight body and slowly opened his eyes to look at the camera.

An orange-red ring aperture is quietly staying in front of the exploration ship.

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

Hope swallowed and said with difficulty.

Next second.
Chapter completed!
