Heavenly Feather Immortality Season 1

Lu Qing'an burns plants to extend his lifespan, hiding cautiously for ten thousand years until his life force becomes infinite and eternal. One day, he is forcibly taken to the Immortal Realm by a female deity, only to discover that lifespan serves as currency there, exchangeable for legendary treasures. With weak cultivation, he trades his life force for divine weapons to protect himself; lacking a powerful backer, he directly purchases the top sect to control it from behind the scenes. Throughout the story, the protagonist moves steadily and develops slowly, using his endless lifespan to counterattack and dominate the Immortal Realm.
