Sign-In All-Purpose Repairman: A Big Shot Hiding in a Humble Shop

After transmigrating into the modern city, Lin Yu loses his job from the start, then unexpectedly binds himself to the God-Tier Repair System. Daily sign-ins unlock max-level skills. Antiques, luxury cars, electronics, even chronic illnesses: anything he works on can be perfectly restored and increase in value beyond belief!

He repairs an old Nokia and cracks a top-secret international hacker password. He fixes an ordinary old wooden chair, scrapes off the paint, and discovers thousand-year-old rosewood, making hundreds of millions overnight. While others spend all day repairing cars, he tightens a bolt and builds a world-class engine. As for terminal illnesses that stump famous doctors, a few silver needles are enough for him to bring patients back from the brink.

All he wanted was to quietly run a repair shop and live a peaceful life. Instead, a cold, high-powered CEO shows up with a wrecked luxury car and accidentally exposes his many secret identities: top antique collector, reclusive feng shui master, mysterious billionaire on the global stage... They're all him!

The CEO is completely dumbfounded and presses him to reveal how many identities he has. Wearing an old apron, Lin Yu smiles faintly: I'm just a repairman with a few all-purpose skills, taking it easy while I happen to be a billionaire!
