My Mastery System Levels Up Everything!

Luo Ke is a \"crane's tail\" in the Aura Era, an orphan barely scraping by with odd jobs. With an abysmal 46% aura fit, the martial arts college entrance exam is a death sentence. His bully, a 90% fit prodigy, relentlessly mocks his impossible dream. But after a near-death encounter, Luo Ke gained the \"Xueba System.\" This isn't just a cheat; it instantly transforms 'wealth value' into perfect mastery of any skill. He's just earned enough to upgrade \"Basic Pharmacy.\" The exam begins. Luo Ke, expected to fail spectacularly, finds himself instantly solving questions that stump even top students. Now, the system whispers: \"Basic Pharmacy mastered. Next: One-Star Potion creation – success rate 10%.\" How will this sudden, hidden mastery shock the world that once scorned him?
