After defeating the Observer, Rhombus, at the isolated space station, the crew of Ark 531, led by Xuanxian, were coerced by Wisfuyi and others into undertaking a trial for all humanity in the End Star Nebula, beyond the territory of the Ark space station. After enduring one human conflict after another, along with battles between planets and star systems, this group of people was reborn in a different way. They later rose up with renewed resolve to fight the corrupt technology left behind by the Ark Civilization. Their goals were to save Earth, cleanse the corrupt civilization, and purify Earth, the entire solar system, and humanity itself.
This End Series will serve as a major precursor to the next series, Extinction. In the end, the next generation, led by Xuanxian, founded a new Genesis-era human civilization dedicated to the struggle to cleanse the solar system. Only then did humanity truly break free from the colonial rule of the Ark Civilization. Later, Xuanxian led an army of one billion Contract-Bearers in a counterattack against the more than 1.7 billion remaining members of the Ark Civilization, completely destroying it in the final battle and avenging the bloody feud that had lasted for over a thousand years.
After their vengeance was fulfilled, humanity’s civilization plunged into large-scale civil war and internal strife for its own reasons. In the end, the defeated faction refused to accept the outcome and launched a plan to flee under the pretext of sending a colonization fleet to other star systems. Leading the remaining 104 million people, they escaped until they reached the Yuanyan Star System, where they continued their tireless struggle to revive humanity.
