The path to immortality through martial arts begins with being forced into marriage

When Cui Yi opens his eyes in a new world, he finds himself inhabiting the body of the sole heir to a once-proud immortal cultivation family—now reduced to little more than a crumbling estate and a legacy of failure. Worse, his unexpected new life comes with an unconventional and deeply awkward household: an unmarried sister-in-law who has yet to officially join the family, and a child bride who is far too young and far too eager, frequently declaring her intent to bear his child. Faced with what seems to be a script written for certain doom, Cui Yi braces himself for a short and miserable existence. But just as despair begins to set in, a long-dormant power awakens within his consciousness—an ancient, mysterious nine-story pagoda, its presence thrumming with forgotten knowledge. "The Nine-Layered Pagoda is the foundation of the Dao; with your longevity, you will illuminate the path of change," it whispers. While others painstakingly cultivate through talent and rare resources, Cui Yi discovers a terrifyingly simple alternative: he can trade his own lifespan to fuel his ascent. At first, the cost seems impossibly high, until he makes a brutal realization—slaying demonic beasts and wicked cultivators replenishes his years, turning slaughter into sustenance. Suddenly, the path to immortality is no longer a narrow, treacherous road, but a wide-open field of opportunity, paved with the corpses of his enemies. The only question that remains is just how far he is willing to go.
