SCAVENGER: I Can Extract Stats From Everything!

One man’s trash is another man’s God-Tier loot drop. When the System integrated with Earth, humanity was judged solely on their potential. Athletes became [Warriors]. Geniuses became [Wizards]. Leaders of the faith became [Paladins]. Silas Kane, though? He was a broke engineering dropout working the graveyard shift at a scrapyard.The System gave him a trash-tier class: [Scavenger]. Rank F. His skills were useless. His stats were garbage. He was destined to be fodder for the first wave of monsters. But the System made a mistake. It gave Silas a unique class skill: [Concept Extraction]. While other players are risking their lives to find a Rare sword in a dungeon, Silas is in the junkyard.He touches a rusted car engine and extracts the concept of [Combustion].He touches a bank vault door and extracts [Impenetrability].He touches a high-voltage transformer and extracts [Lightning]. He doesn't need to find legendary gear. He can build it out of a toaster and a roll of duct tape. The world may be dark, and full of terrors, but Silas will slay them all and then extract the thing that made them deadly in the first place.  He's on a journey to prove himself, and move the [Scavenger] class up to Rank S.
