To the south of the star Cygnus ο1, 1,480 light-years away from Earth, a huge star three times the diameter of the Sun is shining.

The star slowly rotates, revealing a breathtaking scene on its back.

Countless thin and light objects in the shape of a large number of sails cover nearly a quarter of the surface of the star, and the light pressure on the surface of the huge sail counteracts the gravitational pull from the star, maintaining a subtle and relatively stable state in between.

At an altitude of 100 kilometers above the surface of the sail, a planet with a diameter of about 3,000 kilometers is slowly orbiting a huge star like a giant floating city.

But no matter how the planet rotates, it will not break away from the isolation of the sails and face the star. Obviously, the rotation period of a star is exactly the same as that of sails and planets.

The surface of this asteroid, which is more than four times the radius of the Earth, is brightly lit at this time, covering almost half of its area, and it is very lively.

Strangely, it is also covered with a large number of bottomless circular potholes, the small ones are hundreds of meters in diameter, and the large ones are several kilometers or even more than ten kilometers in size, and I don't know what they are used for.

Somewhere on the planet's equator, in a bustlingly lit megacity, tall buildings rise and abound.

The exterior of the metallic building reflects the various spaceships shuttling back and forth in the building complex, busy but orderly, full of technology.

At this time, on the top roof of a two-kilometer-high giant sword-like building, a slender figure with blond hair was sitting quietly with his knees crossed, staring at the stellar sail covering the entire sky in a daze, with a slightly confused look in his blue eyes.

"It's been a long time since I've seen the sun, not even the starlight." The figure is delicate and a little immature, and there is a cloud of sadness on its face, which cannot be torn, and it is talking to itself.

Miraculously, this blonde girl not only looks exactly like a human on Earth, but even spits out a language that is very similar to Chinese on Earth, the only difference is that she has a somewhat broken accent.

"Feeling sorry for yourself again?" At this moment, a chuckle came from behind the blonde girl, and then a tall figure with a graceful posture stepped out.

The man was dressed in a red and blue leather bodysuit, with a giant sword-like pattern pinned to the center of his chest, just like the iconic building beneath his feet.

The standard leather clothes revealed her convex and backward figure, a long fiery red hair casually fell down, and the same delicate face had a more mature and charming taste, looking at the blonde girl in front of her with a smile, with an extremely proud look in her eyes.

"This is just a routine absorption of stellar energy, and in a few days, we will naturally start the planetary engine and leave here to return to aphelion, and then you will be able to see the sun, I really don't know what worries you at such a young age."

The red-haired girl crossed her hands and said helplessly and lazily.

"So what?"

The blonde girl didn't look back, and continued:

"Even if we see the sun again, we can't see a little green, and the last green space on this planet has been transformed into an artificial oxygen field, although the efficiency has increased a lot, but there is no longer a trace of life."

The red-haired girl smiled bitterly and shook her head, and she didn't know how to comfort her, thinking that when she was still young, the proud son of heaven in front of her was still a lively and cheerful little girl, sticking to her "sister, sister" call every day, but now she has become like this.

"Okay girl, you, the only person in human history who has opened the pseudo-heavenly eye, I don't know how many people can't envy it."

"Let's go, the teacher asked us to come over for something, saying that the expedition team had news to bring back."

"Expeditions? Could it be that there are clues to other civilizations? ”

The blonde girl's eyes lit slightly, and the little hands holding her knees suddenly let go, and her petite body stood up lightly with her feet off the ground.

"Just check it out." The red-haired girl chuckled and turned away, thinking that there was finally something that would make the girl a little more interested.

On the top floor of the giant sword-like building, in a solemn meeting hall, there were already more than a dozen figures sitting around the round table.

The walls around the hall are carved with various reliefs, and the main characters in the reliefs are mainly humans, and there are also backgrounds such as the cosmic starry sky and the galactic battleship.

The relief is divided into four parts, the first of which depicts a terrible war between human civilization and a powerful invader, which ultimately left humanity dead and wounded and on the verge of extinction.

The second part is about the fact that in order to preserve the last spark of civilization, they embarked on an interstellar escape journey under the leadership of the civilization leader at the time.

However, the invaders continued to pursue them, and it was not until they finally sacrificed most of them, including the human leaders, that they were able to scatter the few survivors all over the universe, and they could save the last glimmer of hope.

The third part depicts one of the surviving fleets wandering into a strange and inhospitable star system, but there are no habitable planets in this star system where they can directly settle down.

However, with their tenacious will and the technological level of the pinnacle level of the second-level civilization, it took dozens of generations of hard work to finally transform one of the planets close to the habitable zone into a truly habitable planet, allowing them to establish themselves in this star system.

The fourth part depicts the golden period of development after this civilization, as they traveled to all the planets in the star system, establishing planetary bases and habitable places on them in order to keep watch over their home planet.

In the end, they began to make efficient use of the energy of the star in the galaxy, and built a stellar sail of ultra-light carbon nanotubes through molecular robot technology at a high altitude from the surface of the star, so as to gather stellar energy for the survival and development of civilization.

After the fugitive battle tens of thousands of years ago, the entire civilization has finally developed to its current peak.

Obviously, this is a brief history of the development of a civilization, and the protagonist is another branch of human civilization that has fled to the depths of the universe with the human beings on Earth.

"Did this girl Ida go look up at the stars again?"

In the council hall, a kind white-robed old man sitting in it smiled and spoke.

The old man's beard was white, his thin face was covered with deep wrinkles, and although he looked quite old, the astonishing fluctuations in his black pupils showed that he was not as weak as he appeared.

"What kind of starry sky can be seen in this hellish place, it's good if it's not baked."

Another burly middle-aged man with a knife-like face replied lightly, the golden curls of his shawl seemed random and messy, but they were chaotic and orderly. The momentum that the man occasionally leaked made his robe agitated, and it looked a little domineering and exposed, so that many people unconsciously stayed away a little.

"Baldwin, take that momentum from you, this is not a battlefield."

A gentle and majestic voice came from a middle-aged man with black hair and black eyes sitting between the two men, who was about forty years old on the surface, dressed in a golden robe, with no decoration other than the pattern of a giant sword on his chest.

The man's face was flat, but he was not angry.

The blonde man named Baldwin was not dissatisfied when he heard this, took a deep breath, restrained his breath, and said lightly:

"Sorry, just broke through, it's still a little unstable."

"Congratulations!"

"Congratulations to the Consul!"

“......”

As soon as Baldwin's voice fell, congratulations poured in.

"Broken through to the Fourth Turning Skywalker?" The black-haired golden-robed man was also a little surprised, and then asked with a smile.

"That's right, it's not easy to get to this point." Baldwin shook his head and smiled wryly.

"I thought you'd keep a low profile for a while." The white-haired old man had obviously seen Baldwin's true strength for a long time, and as the strongest celestial master of the current human civilization on Tabi Star, the contemporary science and technology archon, this was naturally difficult for him.

"Who broke through?" At this moment, a clear voice came, and then the figures of the blonde girl and the red-haired girl appeared in front of everyone, exuding a youthful atmosphere, which made many old guys present feel a lot younger.

"Alas, the yin is prosperous and the yang is declining!" The black-haired golden-robed man sighed helplessly when he saw this.

I don't know if it's a yin or a yang mistake, in the nearly 100 years of human civilization in Tabi Star, there have been no more male cultivators with outstanding qualifications, but on the contrary, these two Manli figures stand out from the crowd.

"Teacher, what's the sigh, with the two of us Tabi Shuangjiao here, what else do you need a man to do?" The blonde girl's big eyes blinked slightly, and she changed her previous melancholy look, which was also a little naughty.

"That's right, and our little witch Ida is the second person in the history of mankind to be able to open the false eye of heaven, and she can't say that she can lead mankind back to the peak of the year." The hot red-haired girl was leaning back in a chair next to her and yawning lazily.

"Sister Cynthia, don't kill me again, I can't afford to be responsible." The blonde girl named Ida said with some coquettishness.

"Okay, I'm naturally happy that you two have achieved what you have today, and the entire human civilization on Tabi Star does have high expectations for you, but don't put too much pressure on yourself, let it be."

The black-haired man spoke, interrupting the conversation between the two women, and continued:

"Everyone is here, so I'll tell you the news brought by the expedition."

Seeing that everyone was concentrating, the man tidied up his already smooth and wrinkle-free collar, and said slowly with some solemnity:

"We have indeed found traces of other civilizations, but this is not unusual, after all, the number of civilizations we have discovered over the years is not small."

"What I want to say is that what we have discovered this time is a long-lost fraternal civilization, that is, the descendants of human civilization that parted ways with us 10,000 years ago."

As soon as these words came out, there was silence at first, and then the audience was in an uproar and was amazed.

"Finally, ah......" The white-haired old man muttered to himself, the excitement and joy on his wrinkled old face that could not be concealed, and a trace of crystal color flashed in his dark and clear eyes.
