Lu Cheng, the bottom-ranked student at a vocational school, is framed and forced to wager his enrollment: fix an imported heavy motorcycle that’s been declared beyond repair for three years within three days, or leave on his own. The night he takes off the cylinder head, the old burn scar on his wrist, twenty years old, suddenly starts to heat up. The machine’s cross-section unfolds before him like a book, laying bare exactly who tampered with it. But the bike wasn’t worn out from riding. Someone had deliberately destroyed it, step by step. Starting from a tiny repair shop with only half a front door, he’ll be rebuilding far more than just a motorcycle.
