Global Game: I Can Amplify Everything by a Hundred Times

The world has been gamified. Dimensional gates open across the planet, and alien races begin invading. Humans awaken as professionals with classes and skills. Bai Chen, an orphan looked down upon after his parents died in the beastman wars, awakens a rare hundredfold amplification talent during his class change, along with a hidden Demon-Slaying Swordsman class. With this power he can enhance skill books, equipment, items—almost anything—by a hundred times. Keeping a low profile, he steadily grows stronger by taking on challenges far above his level.
