Age of Cataclysm: I can light up the technology tree

Like the experience of entering the ice giant last time, this journey was also safe and sound.

After passing through the ammonia ice cloud and thunderstorm layer, the [Poseidon II] exploration ship rushed into the boundless liquid ammonia ocean accompanied by the drizzle of liquid ammonia rain.

Unlike the first generation [Poseidon] exploration ship, the second generation exploration ship cancelled the original propeller propulsion device and used a water jet propulsion device in order not to cause the "disgust" of the giant fish.

Compared with the propeller, the propulsion efficiency is much lower, but it is quieter.

Under the illumination of the searchlight, the dark sea water is quiet, and it seems that there is no life in it.

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

They silently turned on the active sonar device and manipulated the exploration ship to the liquid ammonia ocean.

Similarly, in order not to cause the "disgust" of the giant fish, the active sonar device has also been improved to a certain extent-they use the same base frequency as the giant fish to explore the surrounding environment.

…

"In the eyes of the giant fish, this exploration ship may be a speechless fellow."

The day before departure, Lv Yongchang said truthfully.

"Therefore, according to our guess, these curious giant fish may come from a long way when they hear this frequency."

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

"In their world, it should be difficult for such a "strange thing" to appear."

At that time, hearing Lv Yongchang's words, Hope and Hansen's faces changed.

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

"Calm down, calm down." Lv Yongchang noticed the expressions of Hope and Hansen, and immediately smiled and comforted them, "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."

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

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

"After all, we don't have any experimental subjects, so we can only speculate on the existing data."

"But don't worry."

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

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

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

"Think in a different direction."

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

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

"You said, right?"

Looking at Lv Yongchang's expression, Hope and Hansent could only nod stiffly.

...

The [Poseidon II] exploration ship slowly dived in the dark liquid ammonia ocean.

In the cockpit.

Hope and Hansent were using the small game console to relieve their boredom.

"Do you know how to play?"

"Bring it here, my grandma can play better than you!"

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

"Beep! Beep! Beep!"

"Unidentified object detected!" Zero's electronic synthesized voice sounded at this moment, "Preliminary judgment is an amino giant fish."

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

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

"Here it comes!"

Hope's expression suddenly became serious, and he reached out and patted Hansen beside him: "Stop playing, it's time to do business!"

...

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

A huge amino giant fish was circling constantly.

From its movements, it can be seen that it is very confused at this time.

A series of ultrasonic waves expressing inquiries came out of its mouth and spread towards the exploration ship.

...

"What do these ultrasonic waves mean..."

Hope reached out and opened the translation program beside him.

The comparison results soon appeared in the holographic projection.

"It is expressing confusion." Hope's eyes lit up slightly, "Professor Lu is not talking nonsense, it may really regard us as the same kind!"

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

Before Hansen could speak, Zero's electronic synthesized voice sounded again.

"Communication request connection..."

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

"According to the plan, prepare to start the first communication."

Without any nonsense, Lu Yongchang spoke directly.

"Received."

...

Hope carefully selected a few greeting keywords and imported them into the ultrasonic generator.

Start.

A burst of ultrasonic waves that cannot be heard by human ears spread around along the sea water.

A few seconds later, the response appeared.

"It is expressing joy." Hansen looked at the Chinese characters that appeared in the holographic image with excitement, "It is happy to meet its own kind!"

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

This was his first time communicating with an alien creature!

Looking at the words that continued to appear in the holographic image, Hope took a deep breath and suppressed the throbbing in his heart: "Continue to respond."

"Like it, we express joy."

Hansent nodded repeatedly and quickly selected a few key words.

send.

A few seconds passed by.

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

"What's going on...the information is wrong?" There was some doubt in Hope's eyes, and he lowered his head again to check the holographic projection in front of him, "No problem, these are all keywords that express joy..."

"warn!"

The piercing siren broke the tranquility of the cockpit: "The other party is approaching rapidly!"

"Collision warning!"

Hope's expression changed drastically: "Fuck! Professor! There is something wrong with the translation program!!"

Hope could figure out the reason for this anomaly with his toes.

What else could it be than an error in the translation program? !

Lu Yongchang on the other side twitched the corner of his mouth slightly and turned his head to look at Meng Lu beside him.

Meng Lu: "..."

…

"Beep!! Beep! Beep..."

The rapid sirens gradually subsided.

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

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

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

Hope swallowed and spoke with difficulty.

The next second.

The light beam of the main searchlight penetrated the slightly turbid liquid ammonia seawater and shone directly on the giant fish.
