Cataclysmic Era: I can unlock the tech tree

"Don't rush, give me a little more time..."

Meng Lu frowned and quickly selected suitable words from the dictionary.

One minute later.

Meng Lu looked up and pressed the confirmation button on the holographic projection.

"alright."

"Prepare to restart the ultrasonic generator."

"Theoretically speaking, there shouldn't be any problems this time."

I don't know why, perhaps because of Lü Yongchang's influence, she now also likes to say this phrase.

As for Hope and Hansent, they felt a chill run down their spines when they heard those words.

It’s over.

The flag has been raised.

Hope, with a tragic expression, reached out and activated the ultrasonic generator.

A series of new ultrasonic waves emanated from the exploration vessel and spread outwards in all directions.

"Will it work?"

Hope swallowed hard and muttered to himself.

Time passed second by second.

The raging giant fish gradually calmed down.

It remained quietly in place, "watching" the exploration vessel in front of it.

"I still have a bad feeling..."

Hope raised his hand to wipe the cold sweat from his forehead and muttered to himself.

next moment.

The giant fish moved.

On the sonar diagram, a giant fish swims slowly around the exploration vessel.

"Is it confused?" Hope glanced at the text on the translation program, and even more cold sweat appeared on her forehead.

"Researcher Meng, are you sure the current situation is normal?"

"...Theoretically speaking, this is normal." Meng Lu coughed lightly and nodded seriously. "Didn't you see it has stopped its previous deterrent behavior?"

"Don't stop the ultrasonic generator! I think we're about to succeed!"

"Whether we can successfully infiltrate the enemy depends on this!"

Hope glanced at the giant fish slowly circling the exploration vessel: "..."

……

Time passes little by little.

The giant fish seemed tireless, circling the exploration vessel incessantly.

The exploration vessel also slowly rotated to ensure that the main searchlight shone on it.

Hope frowned slightly, staring intently at the porthole directly in front of him.

He could tell from the giant fish's movements that it was conflicted.

Clearly, this unprecedented high-tech product completely baffled it.

Giant Fish: What exactly is this thing?

Hope imagined the giant fish's inner thoughts, a slight smile appearing on her lips.

As for Hansent next to him, he looked at Hope's "perverted smile" with a strange expression and silently moved his buttocks a little to the side of the seat.

At the same time, he shook his head with regret.

"Hope, try this set of words again." Meng Lu's voice came from the speaker, interrupting Hope's thoughts.

"Okay." Hope subconsciously raised his hand and adjusted the ultrasonic generator.

A few seconds later.

His smile froze—the giant fish stopped circling.

Illuminated by the main searchlight, it slowly swayed its massive body and "shakily" swam toward the exploration vessel.

Hope suddenly felt a thin layer of cold sweat on his back.

God knows how he came up with the adjective "awkward" from this hideous deep-sea behemoth!

"Researcher Meng, are you sure...?"

"Is this really normal?!"

Meng Lu: "..."

"Theoretically speaking..."

"Theoretically speaking, I think we should turn off the ultrasonic generator!" Hansent leaned back in his chair, interrupting Meng Lu with a forceful tone.

He watched the giant fish getting closer and closer outside the porthole, tears welling up in his eyes.

I feel like I'm going to have another nightmare.

Compared to the last one, this nightmare must be even more thrilling.

At this moment.

The giant fish had quietly approached the exploration vessel.

Under the horrified gazes of Hope and Hansent, it "lightly" rubbed against the exploration vessel's external armor.

With a loud scraping and impact sound, the entire exploration vessel began to shake violently.

At the same time, the indicator light on the radiation detector next to it began to flash.

"Warning! Neutron radiation detected!" Zero's synthesized electronic voice, accompanied by an alarm, reached their ears. "Radiation dose: extremely low."

"Professor?!" Hansent, his face ashen, stared at the fleeting orange-red ring of light outside the porthole and shouted in his already hoarse voice.

……

Dawn Star.

"Uh..." Meng Lu looked at the image on the holographic projection somewhat awkwardly, "Professor, the source of these words might be their companions..."

Upon hearing this, Lü Yongchang's eye twitched violently.

孽 孽!

"How about I choose another set of words?" Meng Lu asked timidly, realizing she had done something wrong.

Suddenly, Lü Yongchang's eyes lit up slightly, and a faint smile appeared on his lips.

"No, don't change it yet."

As he spoke, he picked up the microphone and cleared his throat.

"Ahem, can you hear me?"

"Professor?!" Hope and Hansent's terrified voices immediately came through the communication device.

That's normal.

Being paired with a giant fish that is over 200 meters long would certainly not be a pleasant experience.

Lü Yongchang expressed his sincere understanding.

So he spoke.

"Don't rush."

"Let's be patient a little longer."

"The second-generation exploration vessel has been specially equipped with a radiation shield, so you will be safe."

……

Hope: "???"

Hansent: "Huh?"

Is this the answer they want?

"Prepare to release some cesium chloride and rubidium chloride," Lu Yongchang's voice came from the loudspeaker. "Since it considers you its partners, you should maintain that identity."

"Try to get it to lead you to that special mineral resource."

Hope turned her head expressionlessly and exchanged a glance with her teammate beside her.

He then sighed deeply, and amidst the slight tremors in the cabin, he raised his hand and reached for the bait delivery device on the other side.

……

A few minutes later.

The giant fish, covered in black-patterned armor, devoured the cesium chloride and rubidium chloride in the seawater and left the Poseidon exploration ship satisfied.

"it's over?"

Hope gazed thoughtfully at the receding orange-red ring of light outside the porthole, muttering to himself, "Just a fleeting glimpse?"

Hansent gave Hope a strange look: "What else? What else do you want to happen?"

Waves of ultrasound were transmitted through the liquid ammonia seawater.

"It's urging us on!"

Meng Lu stared at the translation on the translation device, her eyes widening slightly.

"Quick! Keep up with it!!"

Meanwhile, in the sonar diagram, the distance between the giant fish and the exploration vessel is rapidly increasing.

"It's diving!" Hope's eyes flickered slightly, and without the slightest hesitation, he immediately activated the water jet propulsion system.

"Hancent, follow its ultrasonic signals!"

"Whether we can complete our mission depends on this!"
