A new work from the author of 'My Senior Brother is Too Steady', welcome to enjoy it!-------[Science Fiction Apocalypse Setting + Alone Cultivation Protagonist, Not a Mindless Feel-Good Story]This is a shattered world where human civilization barely gasps for air on a planet ravaged by the Blade Beast catastrophe, the flame of civilization in underground fortresses flickers intermittently, and human elites in space are brewing a final plan to strike back at the Blade Beasts, but the future of humanity is dimly lit by fading stars…“So,”a Mahayana Realm expert, who after cultivating alone for one hundred and twenty-five years failed his tribulation and became a Residual Soul in this 'peculiar' world, sighed deeply as he looked up to the sky:“What the hell does this have to do with me?!”

Lan Chang’an has gone through two lifetimes of reincarnations, and in the third life, he aimed for stability until reaching the Nascent Soul Realm in hopes of unraveling the mysteries of the Nine Seal Stele. Consequently, he cultivated the Ancient Trees Evergreen Technique, which wielded modest power in return for greater lifespan.

His approach is not one of fearlessly engaging in battles, but of navigating with steady precision and forging meaningful bonds with others.

Throughout his long cultivation journey, he encountered individuals at various stages of their cultivation, including a Decent Faction Head, a Prodigious Beauty, a Giant Demon Lord, an Evil Cultivator, a Thousand-Year Old Demon, and a Puppet Master Pulling Strings From Behind The Scene.

Observing the ebb and flow of the world, witnessing its ups and downs, he unknowingly became a living fossil in the realm of cultivation, akin to an evergreen tree spanning through eternity.

In the world of mortals, the flow of life is steady, shrouded in the illusion of longevity, yet decisions are made decisively, with a clear sense of morality.
