I'm a Fake Boss

My name is Lin Chen, and I'm in a panic right now. I traveled to a big boss with all professions at full level, and then the system had a blue screen, and all skills were destroyed... Rich people call me a miracle doctor, drivers call me a car god, and gamers call me the King of Games. But I actually don't know anything! I can't pretend anymore, what should I do? Waiting online, it's very urgent!
