Stockpiled 250,000‑year lifespan in Mortal Realm, I’m a tycoon after ascending to Immortal Realm.

Lu Qing’an accidentally burns a wild grass by the roadside and unlocks a strange power: destroying all living things increases his lifespan. Slaying beasts or incinerating plants‑‑any obliteration of life adds to his lifespan, with gains determined by how vital the creature is. Cautious by nature, he lies low for over ten thousand years and amasses a total of 250,000 years of lifespan. Most Great‑Vehicle experts of the Mortal Realm only live for ten thousand years; as long as he is not killed, he is practically immortal. Yet fate shackles him. Though he stands atop mortal power, he cannot break free to ascend to the Immortal Realm. Time passes. Peer geniuses around him perish one after another when their lifespans run out, including his only close friend. Lu Qing’an can only watch his old companion depart and lives in seclusion deep in the wilderness. Three years later, a formidable purple‑robed immortal descends from heaven, shatters layers of defensive formations, and forces all Great‑Vehicle cultivators from the mortal world back to the Immortal Realm. Thrust into this brand‑new world, Lu Qing’an learns that lifespan is incredibly precious here and can even circulate as currency. Vulnerable with low cultivation? He spends massive lifespan for high‑grade immortal artifacts for protection and detonates treasures to devastate foes when outmatched. Plotted against without sect backing? He splurges lifespan to buy a top‑tier sect and rules from the shadows. Endowed with boundless lifespan after ten thousand years of mortal seclusion, he sets out to forge his own unrivaled legend across the Immortal Realm.
