Thirty years ago, humanity discovered the existence of another dimension. It was called the Forsaken World. A mysterious realm filled with terrifying creatures, ancient civilizations, forgotten treasures, powerful weapons, and supernatural resources beyond human imagination. When humanity discovered that every eighteen-year-old could awaken a mysterious Forsaken Mark granting access to this world, civilization changed forever. Those who awakened powerful marks became celebrated explorers, wealthy elites, and legendary warriors. Those with ordinary marks struggled to survive in a world where strength determined everything. Leeion Volder was never supposed to become special. After transmigrating from Earth into the body of an eighteen-year-old young man, he found himself in a world where the Forsaken World offered humanity its greatest opportunities and most terrifying dangers. His awakening ceremony seemed disappointing. A Common-grade Forsaken Mark. An ordinary beginning. But hidden beneath that seemingly insignificant awakening was something extraordinary. The Infinite Skill Panel. A mysterious system that allowed Leeion to learn skills, improve their ranks, and evolve ordinary abilities into extraordinary powers. Unlike other explorers, who spent years mastering individual techniques, Leeion could acquire skills through observation, practice, manuals, and encounters with creatures. Even more incredible, every creature he killed in the Forsaken World rewarded him with Skill Points. And those points could be used to upgrade his abilities. A simple sword technique could become a legendary sword art. Basic physical training could evolve into an extraordinary body cultivation technique. An ordinary movement skill could eventually become supernatural speed. And the abilities of terrifying monsters could become his own. But the Forsaken World holds secrets far greater than humanity understands. Beneath its countless territories lie forgotten civilizations, ancient rulers, terrifying beings, and mysteries connected to the origin of the Forsaken Marks. As Leeion grows stronger, he begins uncovering secrets that could change the fate of both worlds. From an ordinary awakened explorer to a legendary hunter. From a lone survivor to the master of countless evolved abilities. His journey begins with a single kill. In a world where everyone is given a mark, Leeion has been given the power to evolve without limits. The Forsaken World will soon learn the meaning of true evolution.
