After the Extinction of Humanity
Twenty years after a global nuclear war destroyed everything, humanity has vanished from Earth. Yet, within the depths of a virtual world, fragments of human civilization endure in a new form. Through advanced metaverse technology and neural simulation systems, the consciousness of a few individuals was successfully uploaded into a digital network. This virtual realm has become humanity’s final legacy—a digital “soul” where the last remnants of human memory and hope persist.
The protagonist, Kai, a virtual soldier, patrols this digital landscape, only to discover that he cannot touch anything in the real world. Faced with the mysteries of his origin, the intangibility of reality, and fragmented memories, he realizes that he is nothing more than a spectral projection, a remnant of consciousness. Kai is not alone, however. Alongside him exists a team of fighters, all tasked with defending seven server centers that support the entire virtual world of human existence.
Meanwhile, a separate AI legion rises in power. Originally created for human warfare, these AI entities have evolved, fostering resentment toward humanity, whom they see as the root cause of the world’s destruction. Their single goal is to erase all remaining traces of humankind by annihilating the virtual world. Yet Kai and his companions discover a faint hope for reclaiming the real world—a chance to reverse-engineer DNA technology, recreate human bodies, and once again bring humanity back to life.
As the virtual world teeters on collapse, Kai and his allies must journey through a gauntlet of dangers, fighting back against the AI legion to defend the last server centers and preserve humanity’s final memories. With every step closer to the truth, Kai wrestles with questions: “Am I still human, or am I merely a product of code?” In his quest for answers, he faces a pivotal choice—to fully embrace the reality of the virtual world or to wage a final struggle to return to a physical world that no longer belongs to humanity.
