Chapter 389: The Development and Shackles of Lousu Yi

```

Crisis Era 1020.

After a voyage of 580 years, Human Star Alliance International finally arrived at Lousu Yi, also known as Aries Beta, the second brightest star in the Aries Constellation.

Lousu Yi is a spectroscopic binary star, a type of star system where the stars are so close together that their companion can only be detected through spectroscopic analysis. The primary star is a blue-white A-type main sequence star, and its companion is a G-type main sequence star.

Based on the spectral classification of stars, they are primarily divided into seven types: O, B, A, F, G, K, M, with the size and brightness decreasing sequentially, and the lifespan increasing sequentially.

A-type stars, which are cooler and dimmer than O and B types, have surface temperatures 1.5 to 2 times that of The Sun and a brightness between 5 to 50 times that of The Sun, living for tens of millions to several hundreds of millions of years.

The F, G, K, and M-type main sequence stars are successively referred to as yellow-white dwarfs, yellow dwarfs, orange dwarfs, and red dwarfs. F and G types are the star types most likely to have Earth-like worlds, K types are most likely to have water worlds, and M types tend to have frozen celestial bodies.

The two stars of Lousu Yi, one an A-type and the other a G-type, have a stable planetary system due to their proximity. It consists of two Earth-like planets and three gas giants, as well as an outer belt of small celestial bodies.

There were several reasons Human Star Alliance International chose this place:

First, the stars in the vicinity are mostly dim red dwarfs with planetary systems too close to the star, posing a certain obstacle to the development of a large-scale civilization.

Second, although this stellar system was born only a few hundred million years ago, it was now in a stable period, and it will remain stable for several hundred million years to come, providing a solid foundation for the habitation of humans.

Third, the planetary system is highly favorable, located at a good distance from the star, yet receiving substantial light and heat, making it lie in an optimal habitable zone.

Fourth, the Human Star Alliance International actually did not want to stray too far from the Solar System, and a distance of 59.6 light-years was most suitable. In a sense, they were "ordered" to flee, not fleeing in the sense of betrayal.

When they departed, they all understood that the escape surveillance system and the Thoughtcontrol were actually encouraging them to leave behind seeds of civilization for humanity. In their hearts, they always harbored a deep affection for the Solar System, a complex emotion forged by history and responsibility, even anticipating the day they might reclaim the Solar System.

They had not experienced the doomsday battle and did not know about the Dark Forest. Although they had some conjectures about the cruelty of the universe and even the Dark Forest, they did not fully embrace the concept of the Dark Forest, and harbored a faint romanticism about civilization wars.

Thus, in this distant place nearly 60 light-years from the Solar System, humans found their new home.

The Trisolarans would almost certainly not discover them; here, they silently amassed strength, hoping that in a millennium, humanity might possess the capability to initiate that magnificent journey to reclaim the Solar System.

Of the two Earth-like planets of Lousu Yi, the second planet has a diameter approximately 1.1 times that of Earth and an average surface temperature of about 12 degrees Celsius, with a relatively high rotation speed, magnetic field, oceans, and an atmosphere similar in density to that of Earth.

This is the most Earth-like planet humans have discovered to date, but it has not given birth to life, nor does it have an ecosystem.

However, such planets are actually more suitable for human colonization. If colonizing a planet with an ecosystem, the first requirement is to modify one's own body. Otherwise, even if the atmosphere of the planet is identical to Earth, a single breath could introduce countless microorganisms and germs that may cause severe illness or even death.

The differences between species in interstellar space are vast; we cannot change a planet's inherent ecosystem, only ourselves.

In fact, humans are now an interstellar civilization; the real objects of colonization are stellar systems, not planets, which more often act as repositories of resources. Even for today's humans, living on the surface of a planet would require certain modifications.

When humans finally set foot in this chosen star system, a hitherto unprecedented journey of rapid civilization development quietly commenced.

On the surfaces of the planets, various resource extraction bases and refineries were constructed en masse, and towering space elevators stood tall, piercing the bondage of the atmosphere and becoming bridges connecting heaven and earth.

And in space, majestic base facilities dotted the sky like stars. They were not just cold structures, but the lifelines that supported the continual expansion and progress of this interstellar civilization.

Population development was also a top priority. Only with a sufficiently large population base can there be a continuous stream of power and creativity for in-depth exploration in scientific research, rapid industrial development, and the cultural prosperity and flourishing of various fields.

The era of great construction of the Star Alliance International arrived, which was also an era that witnessed human intelligence and courage.

...

Crisis Era 1060.

The first batch of new humans born under the dawn of the new era quickly grew into the main force driving the great wheel of civilization forward.

In that year, the synchronous orbit super collider was completed, and humanity also welcomed an unprecedented explosion in fundamental theory.

The Star Alliance International officially became a Level 1.1 civilization.

Crisis Era 1097.

The Human Star Alliance International Sophon experiments began, marking another revolutionary leap in the history of technology, as if a new engine was installed on the civilization's vessel; technology afterwards experienced an unprecedented period of development.

Crisis Era 1104, Era of the Divine Vessel 585.

Just as humanity was immersed in the limitless joy brought by technological advancements, an unexpected storm quietly shattered this tranquility.

Star Alliance International likewise observed the Hines Strike that had befallen Kuruo Three—a cruel and efficient cosmic extermination mechanism, silently proclaiming the universe's indifference and peril.

At this moment, the Divine Vessel Civilization was in the Wang Liangyi Star System, approximately 54.7 light-years from Earth, thus they observed this Hines Strike five years prior to the Divine Vessel Civilization.

This incident was confirmed to be "man-made," revealing the dark laws hidden deep in the cosmos. Star Alliance International also learned the art of concealment, and the Dark Forest theory quietly took root in their hearts.

Even so, humanity's technological development was not greatly affected; they harnessed the technology of The Waterdrop, Sophons, and Glue Bullets… Human lifespans broke through limits with an average life expectancy reaching 400 years.

Crisis Era 1156.

Star Alliance International made a significant breakthrough in Curvature Technology, the Curvature Drive Engine project succeeded, but people also discovered the spatial effects caused by curvature. Star Alliance International ultimately prohibited any large-scale validation experiments regarding Lightspeed Spacecraft.

Yet, humanity's technological advancement did not pause because of this; it continued to flourish.

Crisis Era 1328, Star Alliance International made breakthroughs in Re-aggregation Technology, officially becoming a 1.2 level civilization.

Crisis Era 1452, Star Alliance International achieved breakthroughs in Vacuum Zero Point Attacks, which might be their last moment of glory.

After four centuries of rapid technological development by Star Alliance International, humanity seemed to be shackled, with technological advancement having hit a pause, as if, like the Dinosaur Civilization, their technology had been locked up.

At this moment, humanity was still immersed in self-spun illusions, believing it to be just a temporary rest, oblivious to the lurking crisis.

Crisis Era 1644, the technological shackles that persisted for two centuries finally awakened humanity from its dream, making them aware of the severity of the problem.

Future History studies also emerged in the new world, suggesting interstellar colonization as the best way to break the technological shackles. Numerous voices emerged among humanity, yearning to pioneer new worlds; the Lightspeed Spacecraft project was initiated, a longing to shatter the shackles and continue the brilliance of civilization.

However, in the same year, Star Alliance International observed another star undergoing a Hines Strike.

And this star was Sky Warehouse Five, which is only 12 light-years from the Solar System and also lauded as the star most similar to The Sun in the universe.

This event, like a bolt from the blue, shocked the entire civilization and instantly silenced those voices calling for the opening of new worlds. Humanity finally realized that the universe was not a gentle Cradle but a Dark Forest fraught with crisis.

The Lightspeed Spacecraft plan was shelved, and even many humans called for the destruction of the Lightspeed Spacecraft.

As time passed, humanity gradually lost its pioneering courage, and Star Alliance International fell into unprecedented decline and degeneration.

The new generation of humanity that had never experienced the painful wars of doomsday grew up in smooth sailing, ultimately lacking the courage to face brutality.

Zhang Beihai might have foreseen something, but he was still a warrior, powerless in such situations.

After preparation, Zhang Beihai entered hibernation.

PS: This deviates from the original text; it's not about the choice of direction for escape.

Instead, in the original story, it's about the timing of Cheng Xin and Ai AA's meeting with Guan Yifan in the DX3906 star system.

According to the original text, they reached this star system 286 years after the Solar System was two-dimensionalized. It's also the Year 409 of the Galaxy Era, which is presumed to be the calendrical system adopted by the Human Fleeing Fleet.

The Human Fleeing Fleet truly began its escape during the Broadcast Era. In just over 300 years, it traveled more than 286 light-years and developed four primitive star systems, an impossible feat.

The original text also states, the Human Fleeing Fleet would need almost a thousand years to reach the next target star system.

Even with only seven scholars on the Human Fleeing Fleet, all precious and in hibernation, even with access to The Waterdrop and some information on the Four-dimensional Fragment, it would be impossible to spark a scientific revolution on the fleet that would turn it into a Lightspeed Spacecraft, right?

The Solar System humans are in the Broadcast Era; with the Sophon Blockade lifted by the Trisolarans, human technology rapidly developed. At the same time, the Solar System Accelerator was constructed, and after over half a century of effort by a vast number of researchers, the Lightspeed Spacecraft was finally completed, with only a 35-year delay.

Whereas on the escaping Fleet, achieving a Lightspeed Spacecraft is nearly impossible, at least it would require finding a suitable star system and decades of development.

Therefore, 286 years after the Solar System became two-dimensional, Guan Yifan could not have reached the DX3906 star system.

Here the author assumes Cheng Xin simply remembered wrongly; perhaps Cheng Xin actually arrived in DX3906 a millennium later, and in just a few centuries the Human Fleeing Fleet would not have developed to such an extent.
