The shield jumps rapidly from galaxy to galaxy.

The glimmering inner wall is filled with extremely clear scenes.

It is a giant city in outer space: the mooring round platform at the bottom of the city is like a parking lot, a large number of spaceships come in and out, and there are 100,000 space elevators that transport up and down, connecting to the surface, at a glance, like a glass rain curtain between heaven and earth.

Tang Hong was surprised and envious: "The space elevator that only exists in the imagination of science fiction? If the original world can have such a level of science and technology, no matter how big the crisis is, I am afraid it will be a trivial matter!"

"Remarkable. ”

"This is a three-level civilization...... An interstellar civilization enough to conquer the galaxy. After the exclamation, he regained his composure, and Tang Hong pondered.

After a little thought, there were countless thoughts, and he was about to speak, but he heard a chuckle, and Bei Ni's fingertips slowly wrapped the black hair on his shoulders: "This is not a third-level interstellar civilization, the space elevator and the giant city belong to the category of first-level civilization." ”

Beli pursed her lips with an effort.

But I couldn't help but laugh out loud.

You must know that she only intercepted the light and formed an image to present in front of Tang Hong's eyes...... And these rays have been propagating in the vacuum of the universe for millions of years, the same planetary scene millions of years ago.

Beni explained, adding, "At that time, they were attacking towards a second-level interstellar civilization. ”

"Oh?" Tang Hong instantly understood.

Compared to the vastness of the universe, the speed of light is average. For example, the explosion of the Milky Way galaxy, according to the speed at which light travels in a vacuum, it will take millions of years before it reaches the Andromeda galaxy.

Turn.

When people on Earth look up at the night sky, the source of the starlight twinkle occurred in the distant starry sky a long time ago.

Flashes of lightning, flashes of light, changes in the surface of the frescoes inside the defensive shield - in the center of the planets, huge machines resembling offshore oil rigs surround the stars, extremely slender tunnels, like straws and cylinders, inserted into the interior of the star, I don't know what is being built.

There are also four or five rotating metal rings.

The picture flickered and accelerated wildly, as if compressing the time of a thousand years into a second, and the number of rings skyrocketed, and the superimposed and criss-crossed ring structure contained indescribable beauty.

This is the power of a civilization!

Tang Hong's eyes were straight!

Beni: "They have to master the energy of the entire star! However, the amount of work is huge, and it takes a long time, and it will continue to be built from generation to generation, and it needs to be careful and careful during this period, after all, it is the only star energy source." ”

"In case the star goes out......"

"There is no other star in the vicinity of a million light-years...... At that point, civilizations that have lost their stars will fall into extinction. ”

Despite the risks, they are standard second-tier civilizations as long as they are successful.

"It's a groundbreaking project. Tang Hong looked at it carefully, and suddenly there was a sense of déjà vu.

Less.

Tang Hong blinked, the corners of his mouth twitched, and a word popped up in his heart: Dyson sphere! The technology conceived by science fiction is to build a sphere that wraps around stars, and to put it bluntly, it is a nuclear fusion reactor that uses stars as a power source.

This giant structure, which encircles the entire star, can not only be completely enveloped and impregnable, but also obtain the vast majority of the star's energy output.

A moment later.

Dazzling stars disappear.

Instead, there is a silver light source.

In Tang Hong's eyes, it was like a transparent football, wrapped in glowing core energy, and those ring structures were no longer visible.

This is a second-level civilization. ’

No matter how much I heard Bei Ni say before, he only had a general outline of the hierarchy of interstellar civilizations, vague, and had no specific concepts.

It wasn't until this moment that I was really shocked.

Build a Dyson sphere? Such a civilization is actually only second-level!

'What about a higher level of civilization?'

'Level 1 to Grade 7...... Above the seventh level, [Pseudo-Omniscience] and [Pseudo-Omnipotence]. Tang Hong was completely speechless.

He thought for a moment and asked, "How many years have you fast-forwarded?" ”

"The stellar energy container took a total of 3,900 years to build, and the potential of this civilization is not bad. "They realized that the Milky Way was too far away, and the Andromeda Galaxy was a little farther away. If this continues, sooner or later there will be a time when the energy will run out, and it is destined to fall into silence. ”

"So gamble everything and get out. ”

"Civilization can only survive if it escapes. ”

Bei Ni turned his head to look at Tang Hong: "Before the construction of their star container was completed, thousands of escape spacecraft had already been launched. Unfortunately, the spaceship ran out of energy, and it all became a floating grave. ”

Listening silently, Tang Hong shuddered.

The home planet that gave birth to them, although it provides nourishment for the advancement of civilization, has become an isolated island in the middle of the galaxy isolated from the outside world, almost a desperate situation.

The picture that catches your eye is still changing.

Starting from the silver sphere, beams of dazzling light burst out, leaving only a trail of flames, a brilliant afterglow, like the trajectory of the ship's departure—apparently with the container of stellar energy, it is capable of building more giant ships.

At the beginning, there were a lot of beams, scrambling to be the first, and hundreds of boats flowed.

Gradually, the beam became less and less sparse.

Eventually, the silver orb and the surrounding planets were dead, with no beams coming out...... Each ray of light represents the escape of a spaceship at nearly the speed of light, symbolizing the flame of civilization and the hope of the continuation of the race...... At the same time, all the planets have undergone a series of transformations, as if there is a huge push, and the brushes are moved to the side of the silver spheres, avoiding the waste of light and heat to the greatest extent.

I don't know how long it took.

Hundreds of millions of miles away, the dark and dead vacuum, from time to time fluctuated, seemed to have a terrifying gravitational pull, as if something was colliding.

Empty areas distorted.

Tang Hong couldn't understand it.

"They're working on the technique of curvature navigation. ”

The Dyson sphere, which travels at the speed of light, is a second-level civilization technology.

Curvature navigation is a faster-than-light flight, as well as the transformation of neutron stars, which is a third-level civilization technology.

Cosmos is not flat, there is an arc curvature - the curvature technology studied by the isolated island civilization is to create a state of space depression in the area of the head of the spacecraft, which can be regarded as the spacecraft entering a gravitational field and falling towards the center of gravity, but the center of gravity moves forward with the movement of the spacecraft.

Tang Hong was silent for a while: "What are they called?"

"Island civilizations, they are carbon-based creatures like humans...... It looks like a jellyfish, and it should be delicious when steamed. ”

Follow.

She clapped her hands again: "They've finally figured out the curvature engine, but unfortunately the first ship with the curvature engine exploded." ”

It's so miserable, Tang Hong tugged at the corners of his mouth, but he didn't think Bei Ni was gloating.

The pessimism of humanity is not shared with each other, let alone alien races. Moreover, Beni is not a human being, but a higher life in another parallel world.

"The isolated island civilization is a bit miserable, and the second curvature spaceship also blew up. ”

"Next ......"

"Blew up again......"

Beni giggled and explained, "It looks like they're in a hurry. "To achieve a breakthrough in curvature navigation technology, we also need matching materials, and all aspects have to be adjusted, like bullet trains and airplanes, which are completely different modes of transportation.

Tang Hong was curious: "And then, succeeded?"

"Of course. ”

"As long as the curvature technology is mastered, the rest of the small problems will be solved slowly. Beli laughed, her eyes like a crescent.

Suddenly.

She points to the inside of the shield.

I saw a particularly small spaceship emit a strong brilliance, and the surrounding space was distorted, as if it was being dragged by a terrifying gravitational force.

Swish!

The spaceship disappeared without a trace!

Bei Ni: "Let us warmly congratulate the official success of the ninth curvature spacecraft of the isolated island civilization!"

Tang Hong took a deep breath, and was also excited, and couldn't help rubbing his palms.

He had some admiration and some emotion, the isolated island civilization is indeed too difficult, the homeland is an isolated island between galaxies, and such a desperate situation is embarrassing.

But......

Anything is possible!

The desperate situation is not desperate, what about the interstellar island, as long as you don't give up easily, grit your teeth, and persevere, you will eventually usher in a bright moment.

Through persistent struggle, he changed the origin of the race, which greatly encouraged Tang Hong.

Although it is said that the isolated island civilization withered, at least before it perished, it did its best to throw the seeds of civilization towards the Milky Way and the Andromeda Galaxy......!

"That. ”

Bei Ni tugged at Tang Hong's cuffs: "Their curvature vehicles only have a maximum speed of light of 1.1111111 infinite circular decimals. ”

O__O “

Is this also faster than light, Tang Hong was speechless, it seems that he still needs to improve.

"Then, how many times the speed of light can the isolated island civilization reach?" Tang Hong raised his eyebrows.

"You're too optimistic. ”

"No more. Bei Ni stared at Tang Hong and said slowly, "The potential of the isolated island civilization has come to an end. For the application of curvature technology, they are always stuck at a little more than the speed of light, unable to break through, and the size of the spacecraft is very limited, so it cannot travel long distances...... Both the Milky Way and the Andromeda Galaxy are more than a million light-years away, and their maximum lifespan is less than 500 years...... Up to now, in addition to the homeland of the isolated island civilization, those departing spaceships, which carry the seeds of the continuation of civilization, have become tombs floating in the dark. ”

As soon as the words fell.

The scene outside the defensive shield fell into darkness, and the next moment the light lit up, and silver balls like gems, jade beads, glass, and crystals appeared in Tang Hong's field of vision.

Silver orbs with a faint hint of fiery red. There are only two dead planets left nearby, and the original blue color is now like black charcoal.

"That's the island civilization. ”

"They're waiting to die. ”

Bei Ni took Tang Hong's hands: "Do you know, your hometown is also like this...... So after the time and space are gone, come with me, don't go back. ”
