Immortality Begins with Slaying Demons

After transmigrating into the body of a menial at an escort agency, Fang Yuan discovered that his cultivation talent was utterly mediocre. But he also found that by spending his own lifespan, he could improve his cultivation talent! Ordinary people live at most a little over a hundred years, while cultivators can live for more than ten thousand. Fortunately, as long as Fang Yuan slays demons and vanquishes evil spirits, he can claim the remaining lifespan of his foes. [Slay an ordinary Demon King and gain five hundred years of remaining lifespan!] Spend three hundred years of lifespan, and your talent skyrockets, making you a peerless genius of the age. [Slay an unparalleled Demon Emperor and gain three thousand years of remaining lifespan!] Spend five thousand years of lifespan, and your talent soars again, making you a once-in-an-age prodigy. [Slay an Earth Store evil spirit and gain fifty thousand years of remaining lifespan!] Spend one hundred thousand years of lifespan, and your talent reaches the level of a born sage. You cultivate at an astonishing pace, a rarity beyond compare. And so, with a snap of his fingers, ten thousand years passed. The number of demons and evil spirits in the world dwindled until they became rare species. As for Fang Yuan, his talent was unmatched throughout the ages, and his lifespan was endless. Even immortals lower their eyes before me!
