Chapter 381 The Alien Civilization Imprisoned on a White Dwarf (4K)

Following the directions of the alien beasts, the Tomorrow Alliance arrived at that interstellar orbit and entered it one by one.

“Let’s be bolder this time,” Li Ye said. “Let’s use the gravitational wave controller to accelerate the moving city and increase the speed to 10 kilometers per hour.”

More than ten hours later, Tomorrow Alliance arrived at its destination.

What appeared in Li Ye's eyes at that moment was a white dwarf star.

On the vast canvas of space, like a forgotten diamond, it radiates a lonely and solemn light.

Its size and shape are not as grand and majestic as those of a conventional planet, but it is similar to that of a planet, yet it contains the mass of almost an entire sun.

Looking at it, the white dwarf's structure appears as a near-perfect sphere, incredibly smooth, without any mountains or pits, only a layer of extremely dense degenerate matter. The entire star looks just like a metal sphere with an absolutely smooth surface.

Above the white dwarf star, there are countless strange beasts.

They resemble octopuses, covered in dark brown fur, and have a single, enormous eye on their heads.

Their size ranges from several thousand meters to tens of thousands of meters.

"It's actually a stellar prison!" Li Ye exclaimed.

Using a white dwarf star as a cage to imprison an alien civilization—what a powerful method that is!
Upon seeing the arrival of the Alliance tomorrow, the octopus-like creatures on the white dwarf star raised their heads, each with an expression of ecstatic joy in its single eye.

"This alien civilization can dismantle the stellar bomb; their technology must be advanced enough to save us!"

"Millions of years! That's incredibly long!"

"Get us out of here quickly!"

As is customary, Li Ye communicated with the other party.

He learned that this alien civilization was called "Rost," and that it came from a distant star system and belonged to a high-level alien civilization.

As a civilization of alien beasts, the Rost civilization did not have as many people as the Star Serpents, at most only sixty or seventy thousand. At its peak, the civilization had only about two hundred thousand people.

Millions of years ago, the Rost civilization was unfortunately captured by a high-level predatory civilization when it passed by the edge of the Dagon system.

After thoroughly mocking the alien civilization before them, the predatory civilization imprisoned all of Rost in a nearby white dwarf star.

"Is that so?" Li Ye nodded slowly.

Even without the other party saying anything, he knew that they were indeed a high-level alien beast civilization.

After all, they can withstand the high temperatures of tens of thousands of degrees Celsius and the extremely harsh gravitational forces of white dwarfs, and they can also conduct observations from a distance of more than a million kilometers.

He quickly realized a problem.

"Since you are a high-level alien civilization, you must possess the ability to develop technology. Aren't millions of years enough time for you to develop the technology to escape this white dwarf star?"

Upon hearing this, the Rosts exchanged glances and fell silent.

One of them, Rost, spoke up in anger.

"A technological lock! That damned predatory civilization has set up a technological lock on the entire white dwarf!"

Because the white dwarf is restricted by the technology lock, the Rost civilization is unable to develop technology under any circumstances. In addition, due to the supernormal gravity of the white dwarf, it is unable to escape.

Therefore, they can only pin their hopes on extraterrestrial civilizations passing by the white dwarf star—and these civilizations must be technologically advanced.

But as mentioned before, the edge of the entire galaxy is incredibly vast, and the location of the Rost civilization is just a tiny corner of it.

Over millions of years, the number of civilizations that have passed by a white dwarf is extremely small.

The sudden appearance of the Tomorrow Alliance was a once-in-a-lifetime lifeline for them.

After carefully observing the white dwarf, a strange light appeared in Li Ye's eyes.

These strange beasts even built houses on the white dwarf star.

Building structures on a white dwarf is not as easy as one might imagine. Its surface gravity is a hundred thousand times that of an ordinary planet, and any vertical structure would collapse under its own gravity.

The houses built by the beasts appeared extremely low and vast, like a series of reliefs stretching for thousands of kilometers.

Traditional walls and reliefs are naturally out of the question; there are only continuous, arched domes and honeycomb-like structures that evenly distribute the terrifying gravity of the white dwarf.

Furthermore, Rost and his people built enormous interstellar telescopes and installed energy pipelines on their houses to provide electricity and lighting.

"This alien beast civilization is truly extraordinary!" Li Ye thought to himself.

The entire white dwarf star is practically empty, consisting of nothing but layers upon layers of degenerate matter. Yet the Rosts managed to ingeniously build houses and even supply electricity using local materials.

At this moment, the Rosts of all sizes and shapes were all perched on their houses, their huge single eyes gazing eagerly and longingly at the Alliance of Tomorrow in space.

In reality, the Tomorrow Alliance doesn't dare get too close, because the powerful gravity of the white dwarf could attract all the mobile cities.

"Please, kind passing civilization, rescue us." A Rost said earnestly. "We will repay you with everything we have."

An elderly Rost, with a single, wriggling eye, patiently guides the conversation.

"You can't even easily cross a distance of 142 million kilometers, and you still have to rely on interstellar orbit. It seems you haven't mastered the technology for long-distance space travel. As long as you're willing to let us out, we will impart our technical knowledge to you. Not only long-distance space travel, but also all the knowledge that our civilization has accumulated since its inception!"

Li Ye wasn't in a hurry to name a price, but instead asked a question.

"So how do you plan to help us?"

To escape the white dwarf, the Rosts would need an escape velocity of at least 6500 kilometers per hour, equivalent to 1805 meters per second.

As a high-level alien beast, Rost can only accelerate himself to 500 meters per second—the speed will be even lower under the strong gravitational pull of the white dwarf.

During their millions of years of captivity, the Rost civilization devised various methods.

The most feasible option is undoubtedly the celestial slingshot.

The concept is to drive a celestial body with strong gravity at extremely high speed to pass close to a white dwarf, at which point Rost and his contemporaries can use the gravity of the celestial body to accelerate themselves and escape this stellar prison.

Since it is a white dwarf, simply driving a comet is far from enough; it must at least drive a planetary-sized object.

"In other words, as long as we find a planet, calculate its trajectory, and drive it past the white dwarf at high speed, you can escape this predicament?" Li Ye concluded.

“Yes,” a Rost replied.

In fact, Rost and his team had already identified their targets using interstellar telescopes.

A rocky planet located not far away.

"Once you've decided, get on with it," Rost and the others urged. "Don't you want the technology for space travel?"

"We've thought about it, but we're already capable of developing it," Li Ye replied slowly.

Everything Rost and his ilk said was only one side of the story.

He wouldn't be foolish enough to believe it so easily.

At first, the Rosts patiently and kindly persuaded them to leave the wild and rescue them. However, some of the older Rosts seemed to have changed their minds.

Their eyes flickered, hesitant, as if they were considering something.

Finally, the old Rosts spoke in unison, shouting in aged and mournful voices.

"Kind-hearted human civilization, please don't be fooled by them!"

"Our civilization is an extremely cruel alien civilization that takes pleasure in destroying and fooling the many weaker civilizations in the galaxy!"

"The Rost civilization was exiled to a stellar prison entirely of its own making! We are not imprisoned by a predatory civilization, but by a cosmic enforcer!"

The sudden action of the old Rosts left them stunned.

Once they came to their senses, they instantly became enraged, swarming forward and tearing the bodies of these elderly members of their tribe apart.

Li Ye gave a cold laugh.

"Sure enough."

To his surprise, many Rosts were swayed by these old Rosts and rushed to expose the crimes of their own civilization and their people.

And without exception, they were all killed by their angry tribesmen.

Even when faced with death, they still speak out without hesitation.

"Good human civilization, please destroy our evil civilization!" a Rost cried out before he died.

Li Ye's eyes flickered involuntarily.

Even in the most sinful civilizations, there are still brave, kind individuals who dare to speak out.

After silently paying his respects, he began preparing a plan to destroy the Rost civilization.

The weapon they used was, of course, the rocky planet that Rost and his group had proposed.

This planet will no longer serve as a life-saving celestial slingshot for the Rost civilization, but will instead accelerate directly into the center of the white dwarf, generating an unprecedented shockwave that will kill tens of thousands of Rost.

Upon realizing the intention to leave the wilderness, Rost and his companions were slightly taken aback, and then tried every means to persuade the others to come.

"Don't listen to those guys' nonsense! They've wronged us!"

"Don't you want our gift? This is the scientific and technological knowledge that our people have accumulated over thousands of years. It can dramatically improve your civilization's technological level!"

"So what if we are a sinister alien civilization? The universe is inherently filthy and sinful, a world of survival of the fittest! What you should be considering is not morality and conscience, but rescuing us to acquire scientific knowledge and enhance the strength of your own civilization!"

Li Ye turned a deaf ear to everything Rost and the others said.

Soon, the Tomorrow Alliance arrived near the rocky planet.

At his command, all the mobile cities simultaneously activated their gravitational wave controllers.

A stable and powerful gravitational field was thus created, gradually forming a smooth gravitational slide.

The rocky planet slowly entered the gravitational slide and gradually headed towards the white dwarf.

Seeing this, Rost and his companions were thrown into a panic.

Some panicked and tried to burrow underground for refuge, some angrily waved their tentacles and cursed on the rooftops, while others lay down trembling and crying for mercy.

"It's too late to regret it now," Li Ye said coldly. "A sinful cosmic civilization should be destroyed."

He then ordered all mobile cities to increase their gravitational output, accelerating the collision of the rocky planet with the white dwarf.

However, just as the rocky planet was about to reach the near-Earth orbit of the white dwarf, all of Rost suddenly became ecstatic.

"It's here, it's finally here!"

"This once-in-a-lifetime opportunity has finally come our way!"

"Haha, I can finally escape this damned cell!"

Li Ye was taken aback upon seeing this.

"Could it be that"

Under his astonished gaze, the surface of the white dwarf began to collapse on a large scale, revealing a colossal structure made of ultra-dense degenerate matter that covered thousands of kilometers of the planet's front.

This is a planetary-scale engineering project meticulously constructed by the Rost civilization beneath the white dwarf star—the Gravitational Concave Mirror Array.

It can create an exceptionally strong temporary gravitational field in the near-Earth orbit of a white dwarf in order to capture planets.

Realizing something was wrong, Li Ye immediately ordered all mobile cities to change their gravity output method.

It's too late to relocate the rocky planet now; the only option is to destroy its internal structure through gravity, causing it to collapse completely.

However, the Rost civilization's gravitational concave mirror array not only completely neutralized the Tomorrow Alliance's gravitational attack, but also firmly held onto the rocky planet.

Li Ye broke out in a cold sweat.

From the very beginning, the ultimate goal of the Rost civilization was to get the Tomorrow Alliance to help transport this rocky planet into near-Earth orbit around the white dwarf.

The deaths of many clansmen who had previously been denounced were merely a carefully orchestrated act of self-inflicted suffering, intended to distract Li Ye from focusing his thoughts on destroying the Rost civilization and prevent him from considering whether there were any hidden motives.

Now, this alien civilization has achieved its goal.

Under the influence of the gravitational concave mirror array, the rocky planet began to revolve around the white dwarf, forming a celestial slingshot.

One after another, Rost let out excited roars, using the slingshot to accelerate themselves and escape from the white dwarf.

Immediately afterwards, they charged aggressively towards the Tomorrow Alliance, eventually surrounding them completely.

Just as the Tomorrow Alliance was preparing to commit all its resources to the battle, the ferocious and terrifying expressions on the faces of the Rosts disappeared, replaced by gentle ones.

Under the astonished gazes of the crowd, thousands of Rost bowed to them in gratitude.

"Thank you, human civilization," Rost, the leader, said sincerely.

The Rost civilization was not a cruel civilization of alien beasts, but a peaceful and kind civilization of alien beasts.

What I said before is true; they were indeed imprisoned by a predatory civilization.

The arrival of Tomorrow Alliance is a once-in-a-lifetime opportunity to escape this predicament.

The Rosts naturally knew that this human civilization that had come from afar would not easily trust them.

They chose to settle for second best, staging a self-inflicted wound and sacrificing many of their people in order to convince the Tomorrow Alliance of their "true lies" and thus move the rocky planet.

“After all, gaining the trust of others is a difficult thing, let alone a cosmic civilization,” the leader, Rost, said quietly. “And our people all sacrificed themselves voluntarily.”

Li Ye was overwhelmed with emotion and didn't know what to say.
