Cataclysmic Era: I can unlock the tech tree

"Wait, wait a minute!"

Zhao Zijie's expression changed slightly, and he asked urgently, "Fifty Mysterious Maiden II ships, how many people have come?"

Bart, a smile playing on his lips, announced a number: "Fifty-two."

"Including the two people on duty inside the Luan Bird and the two people on duty inside the Taotie, we are just short of two of you."

Zhao Zijie: "..."

"Didn't we say that once you arrived, we could go back to Mars to rest?!"

Bart shrugged. "Don't ask me, I don't know either."

"Perhaps it's because of the jellyfish; the plan has changed."

"Since the two of you are most familiar with Titan, you naturally cannot leave."

Zhao Zijie: "..."

……

One week later.

With the robots working day and night, a giant basin appeared on the shore of Titan.

The inside of the basin is made of steel with high thermal conductivity, while the outside is wrapped with a material with high thermal insulation.

A large electric heating device is installed at its bottom.

The basin is not deep, and the rim is only a little over ten meters high.

Once the tide rises, the distance between the top edge of the basin and the sea surface will be only one or two meters.

This design also makes it easier for jellyfish to enter.

Overall, the entire trapping device is somewhat like an enlarged version of an electric hot pot.

Although the device is simple in structure and crudely made, it is tantamount to a nuclear weapon for the jellyfish living on Titan.

Inside the Luan Bird Starship.

Zhao Zijie, who had more than a month of experience living on Titan, was put in charge of the operation.

He sat solemnly in the captain's seat, his gaze fixed on the undulating sea of ​​methane.

As darkness fell, Titan, Saturn's moon, entered its eight-day-long night.

Zhao Zijie's eyes flickered slightly.

got windy.

Under the influence of Saturn's gravity and the hurricane, the rising sea surface created increasingly higher and higher waves.

Thick methane rain pattered against the portholes of the Luan Bird Starship, making a soft, continuous sound.

At this moment, Titan revealed its ferocity to everyone!

"They're here," Zhao Zijie said softly, reaching out to press a virtual button on the holographic projection. "Initiate the capture operation!"

The moment the virtual button was pressed, a powerful electric current flowed through the heater inside the "electric hot pot".

In just a few seconds, the temperature inside the "electric hot pot" rose sharply to over -150 degrees Celsius!

This unparalleled "high temperature" instantly vaporized the methane rain falling from the sky!

For a moment, the "electric hot pot" was surrounded by swirling mist, which, from a distance, looked like the steam produced after the hot pot boiled.

Gao Yang and Zhao Zijie clearly realized this, and the two of them turned their heads and glanced at Bart beside them with strange expressions.

He designed and manufactured this trapping device.

Noticing the strange looks from the two, Bart scratched his head awkwardly: "Before coming here, I heard Bai Yixuan and Hong Fan talking about going to Mars to eat hot pot, so..."

Zhao Zijie shook his head helplessly and reached out to press the radio communication button next to him.

"Attention all units, commence the trapping operation."

The moment the words fell, the fifty Mysterious Maiden II ships that were parked behind the Luan Bird Starship rose from the ground in unison, braving the raging wind and rain!

As originally planned, these fifty Xuan Nu IIs were to travel to various areas of the Kraken-Marie Sea and use the Hall thrusters on their bottoms to attract the attention of jellyfish.

……

As time went by, the sea level in the Methane Sea gradually rose.

"Where are the jellyfish?" Bart asked, a hint of anxiety in his eyes. "They're not coming back, are they?"

Zhao Zijie slowly closed his eyes and said softly, "Don't rush."

"Let the Mystic Maiden fly for a while."

A few minutes later, a clear report came through the radio.

"Calling the Luan Bird, calling the Luan Bird, this is area A1."

Zhao Zijie opened his eyes, a glint of shrewdness flashing within them: "Luan bird received! A1, please speak!"

"We've attracted a huge number of jellyfish, the number..." A soft swallowing sound came over the radio, "...a lot of them, the entire sea has turned pale yellow!"

"Understood. Maintain flight altitude, don't go too fast, and bring them over."

"A1 received!"

"Calling Luan Niao, this is area B6..."

"This is area C3..."

As the first communication rang, a series of reports flooded into the Luan Bird's cockpit.

But Zhao Zijie remained completely calm and methodically arranged the movements of each of the Xuan Nu ships.

"A2, suspend trapping and divert some jellyfish to area A1. The navigation route has been sent to you!"

"C3, hover in place, don't let these jellyfish leave!"

"B6, turn back the way you came, you've crossed the line!"

Fifty Xuan Nu starships advanced, retreated, circled, or maneuvered over the Kraken-Mare Sea...

Even the jellyfish in the methane sea obediently "lined up to go into the pot" under Zhao Zijie's command.

Bart stared blankly at this fantastical scene.

"this……"

"Has he always been this arrogant?!"

Gao Yang glanced at Bart and shrugged.

What do you think?

"To be honest, during the training, I remember he only lost one point in all his theory and practical simulation classes combined, right?"

"I heard there's also a 0.5 point for neatness of the paper."

"...Holy crap!" Bart looked at Zhao Zijie, who was focused on giving instructions, with a look of horror.

"Gao Yang, don't just stand there. The jellyfish A1 brought back is almost here. Check the status of the trapping device and prepare to retrieve the jellyfish carcasses."

Gao Yang turned to Bart and shrugged, expressing his helplessness, but replied, "Okay, I'm going!"

Before Bart could even react, Zhao Zijie's order came through.

"And Bart, don't just stand around, go check on the recovery unit. High tide only lasts a limited time, we need to hurry!"

Bart: "..."

While keeping an eye on the condition of each of the Xuan Nu starships, Zhao Zijie turned his gaze to the porthole directly in front of him.

At the edge of the horizon, the Mysterious Maiden II slowly flew in amidst the raging wind and rain!

And in the methane sea at its bottom, endless pale yellow jellyfish churn!

"Gao Yang! Attention, the jellyfish swarm is expected to reach the trap in fifteen minutes!"

……

Fifteen minutes later, Xuan Nu II successfully arrived directly above the killing device.

Attracted by the ultra-high temperature plasma tail flame, these jellyfish climbed up the outer edge of the trap like madmen.

The device's outer layer of excellent thermal insulation material prevents them from feeling any discomfort.

When they "struggled" across several meters to reach the top of the trap, all the jellyfish were "surprised" to find a "deep pit" radiating a lot of heat in front of them.

Driven by instinct, each jellyfish made the same movement.

He took the leap!

Tragedy ensued.

The -150 degree Celsius temperature instantly vaporized the methane inside the jellyfish's skin!

In just a few seconds, the expanding methane gas ruptured the jellyfish's tough outer skin, and their internal organs and body fluids gushed out, slowly sliding down the inner wall of the trap!

As for Gao Yang, he had already opened the collection valve at the bottom.

Countless jellyfish carcasses flowed slowly down the pipes into a pre-prepared storage device.

The extermination plan has thus begun!
