Immortal Demon: Heart's Inquiry

Ten thousand years after a cataclysm tore the continent into nine fragments, destiny reunites them—and awakens a chosen successor haunted by his past life. Branded as humanity's champion against an encroaching darkness, he battles not only ancient demons but the existential question that consumes him: Is he truly himself, or merely an echo of who he once was? In a world where the Demon King's survival paradoxically sustains the light, one young man must confront death itself on behalf of countless souls while unraveling the mystery of his own identity.
