Cataclysmic Era: I can unlock the tech tree

Dear [Painting Artist], I hope you can provide us with some fragments of your body.

We are merely a weak Type II civilization, and in today's Milky Way galaxy, it would be difficult for us to protect ourselves.

Before encountering a pastoral civilization, these two-dimensional fragments could ensure the safety of our civilization.

After editing this string of information, Lü Yongchang checked it again.

A hint of excitement and greed flickered in his eyes.

"Yongchang, you..."

This astonishing move was completely witnessed by Fang Xu.

He swallowed hard, then instinctively lowered his voice and said, "Are you crazy?"

Lu Yongchang suddenly raised his head, a strange smile appearing on his face: "You think I'm crazy?"

"So why do you think they wanted us to pass on their information?"

"They even gave us so many benefits for this."

Fang Xu hesitated for a moment, then said in a lower voice, "You also think that the other side has ill intentions?"

"Of course." Lü Yongchang shrugged.

"Perhaps they want us to distract the cleaners so they can escape."

"Or perhaps, the other party wants to use us as bait to lure the cleaners into a trap."

At this point, he chuckled softly, "Of course, we can't rule out the possibility that the advanced civilizations in the pastoral school are all idealists."

"Regardless of the other party's purpose, one thing is certain."

A bitter look flashed in Lü Yongchang's eyes: "In front of this two-dimensional being, we are just pawns."

"But a chess piece must also have value."

"Our current strength is not even worthy of being a pawn."

"so……"

As he spoke, Lü Yongchang glanced at the holographic projection in front of him, his facial muscles tensed, and he resolutely pressed the send button.

"Since there is no way to resist,"

"Then let's take this opportunity to improve the strength of human civilization as much as possible."

Even if this fire could reduce human civilization to ashes,

Even if this decision might drag human civilization into an abyss,

"I still choose to dance with it!"

"Only in this way can human civilization find a way to survive!"

……

This time, the painting did not immediately respond to the human's message.

Lu Yongchang sat in the chair, silently watching the holographic projection in front of him.

In the projection, the wrinkles on the gray "scroll" on the dark red star's surface became increasingly dense.

Human civilization, do you know what you're doing?

Suddenly, a message appeared on the giant holographic projection directly in front of me.

Compared to previous messages, this one carries a hint of anger.

Even the name was changed from "little guy" to "human civilization".

This is also normal.

Lü Yongchang could also understand the reason for the other party's anger.

After all, in the eyes of [the artist], human civilization is no different from that of an ant.

But this ant is asking for a part of its own body!

After a moment's thought, Lü Yongchang edited another message.

Dear [painting], please forgive our unreasonable request.

However, you wouldn't want crucial information to be unable to be transmitted smoothly due to interference from some less advanced civilization, would you?

Click send.

Violent ripples appeared on the gray "scroll" of the Ross 154 surface.

Even the brightness of the Ross 154 showed some abnormal fluctuations.

Human civilization, I grant your request.

However, I am very disappointed in you!

[You've therefore lost your chance to join the rural faction!!!]

Looking at the information in the holographic projection, Lü Yongchang gently exhaled a breath of stale air.

His stiff body relaxed a little.

The bet was won.

Human civilization will possess a devastating weapon!

As for the opportunity to join the pastoral faction mentioned by the other party?

Don't be ridiculous, who cares about that stuff?

Given the current state of human civilization, joining an organization established by a more advanced civilization would likely result in being devoured, leaving not even a bone behind!

The technological level of a Type II civilization should be sufficient to manufacture a simplified version of a two-dimensional debris stabilization device.

[Make it as soon as possible; I don't have much time left.]

New information flashes continuously in the holographic projection.

In the distance, the gray "scroll" sank once again into the dark red stars.

……

"Professor, data transmission is complete."

Zero's voice rang out in the command center: "Open the file?"

Seeing the progress bar reach 100%, Lü Yongchang nodded without hesitation and said, "Open!"

After a short wait, a huge model appeared before everyone.

Next to the model, detailed data for each component is labeled.

The device is generally shaped like a hollow sphere with a diameter of 100 meters.

The hollow sphere is surrounded by three concentric rings of different diameters.

Three concentric rings slowly rotate around the center of the sphere, which is a gray two-dimensional fragment.

Lü Yongchang stretched out his hand and waved it in the air a few times.

The two-dimensional debris stabilization device model directly in front of it rapidly decomposes.

The internal structure of the three concentric rings was revealed to everyone.

Densely packed coils.

Lü Yongchang raised an eyebrow.

"Magnetic field confinement device?"

But the next moment, he realized there was a problem.

He shook his head and muttered to himself, "No, that's not right."

"The coil arrangement of each concentric ring is different."

"Zero, excluding the other components, model the coils within the concentric rings separately."

"Let's do another simulation to calculate the shape of the magnetic field formed by the coil arrangement of these three concentric rings."

The arrangement of the three concentric rings is extremely complex, and the magnetic field changes caused by the combination of the three concentric rings take several minutes to calculate, even when the result is zero.

In the holographic projection, virtual magnetic field lines gradually appear.

As the magnetic field lines gradually became denser, Lü Yongchang gradually discovered the secrets behind them.

The outermost concentric rings form a huge closed magnetic field, enveloping the entire device.

"Magnetic field shield?"

Lu Yongchang's eyes lit up, and he muttered to himself.

Unexpectedly, the technology of a Level 3 civilization was presented to him in this way.

But clearly, the real magnetic field shield technology is not that simple.

Humans can't exactly put several giant concentric rings around the outside of a starship, can they?

But the blueprints for the two-dimensional debris stabilization device in front of us point the way forward for human civilization.

Lü Yongchang believes that given enough time, he will surely be able to lead his team to break through this so-called technological constraint!

He suppressed his excitement and focused his gaze on the core of the hollow sphere.

The two smaller concentric rings in the inner circle form a complex magnetic confinement device.

A sudden realization flashed through Lü Yongchang's mind.

Leaving aside the other components, the function of these coils is quite simple and easy to understand.

Construct a magnetic confinement device that is strong enough to hold two-dimensional fragments firmly and ensure that it is not disturbed by external charged particles.
