I Sacrificed 10,000 Trash Skills to Obtain a S-Tier Skill and Became Unrivaled

Decades ago, mysterious “Dungeons” appeared in the world, and certain individuals awakened to strange powers called “Skills.” These people became known as Explorers, earning wealth and fame by defeating dungeon monsters. Takegami Noboru is a young man who dreams of becoming an Explorer. However, the unique skill he awakened to—Skill Collection—has a critical flaw: any skill he learns has only one-tenth the effectiveness of normal. Because of this severe limitation, Noboru is ridiculed by everyone as possessing “humanity’s weakest unique skill in history.” One day while exploring a dungeon, Noboru suddenly falls into a trap and engages in fierce battles with monsters. During this desperate struggle, his accumulated skill count reaches exactly 10,000 skills—triggering the awakening of a super-upper-tier skill called Batsuzan Kaisei, meaning “Unparalleled Strength That Can Uproot Mountains”. This extraordinary skill dramatically enhances his physical abilities in proportion to the number of skills consumed. For Noboru, who can infinitely learn skills through his unique ability, this creates perfect synergy—turning his once-mocked “weakest” skill into the foundation for ultimate power. Armed with this supreme weapon, can Noboru finally achieve his dream of becoming a “Hero”?
