Living in the Doomsday and Becoming an Immortal Alone Novel

In a world devastated by the Blade Beast catastrophe, human civilization clings to survival within underground fortresses while space-based elites prepare a final counteroffensive. Yet humanity's future remains uncertain beneath fading stars. A Mahayana Realm cultivator who spent one hundred and twenty-five years in solitary cultivation finds himself transformed into a Residual Soul after failing his tribulation. Awakening in this shattered reality, he confronts an unexpected truth: he must navigate a dying world he never sought to save. This science fiction apocalyptic tale follows a lone protagonist pursuing immortality cultivation in humanity's darkest hour. Unlike typical feel-good narratives, it presents a complex character grappling with existential indifference in a civilization on the brink of collapse. As underground sanctuaries flicker with fading hope and space-based forces mount their final defense against the Blade Beasts, one immortal cultivator embarks on a solitary path through the ruins of the world, asking the question that defines his journey: what does any of this have to do with him?
