Apparently, My Skills Can Evolve and Have No Limits

Two hundred and fifty years ago, Earth changed forever when the Sanctuary appeared—a vast realm of monsters, treasures, ancient ruins, powerful races, and countless floors. Humanity adapted, and now every eighteen-year-old awakens a Status Window revealing their Talent, Attributes, and Skills. Ivan expects nothing special from his awakening, especially after receiving an unimpressive F-rank Talent. Then a mysterious System appears. It allows him to copy abilities from others and, with enough proficiency, evolve his skills beyond their original limits. While everyone sees him as an ordinary F-rank, Ivan secretly hunts monsters, collects treasures, grows stronger, and takes advantage of every opportunity he can find. With 1,000 floors waiting above him, Ivan has only one goal: keep getting stronger—and see just how far his skills can evolve.
