Sign-In Good-for-Nothing: Pummeling My Way to the Top of the City

Lin Yu is the company's universally acknowledged "invisible good-for-nothing." Every day, his coworkers mock him for "not even being able to deliver takeout properly." One day, he accidentally activates a sign-in System and gets master-level combat skills on his very first sign-in in his rented apartment. The next day at work, his former bully of a supervisor deliberately gives him a hard time. Lin Yu strikes back with a move called "Star-Shattering Fist," blasting the man ten meters away and shocking everyone! Later sign-ins earn him luxury cars, mansions, and advanced technology. He casually buys the company that bullied him, punches his way to the top of the city, and becomes a global tycoon.
