In a world ruled by cultivation and magic, the past centuries have been defined by the dominance of cultivators and mages.

For ages, planet-crushing cultivators and world-breaking sages clashed to prove whose path was supreme. Though once equals, time favored the cultivators, whose strength grew with age, while mages faded, limited by short lifespans despite the existence of magical elixirs.

Their dominance waned, until a village boy awakened a strange system. After accidentally witnessing his mother relieving herself, he discovered he could grow stronger through perverted acts, thus starts a bizarre and powerful journey.
