Hidden under the whitewashed security uniform is the Qingyun Sect's last martial arts inheritance. Lin Chen used the pseudonym "Ah Chen" to hide in Boyue Mansion and work as a security guard. Every day he listened to the owner's perfunctory "Hello, security guard!" And clutched the bronze dragon pattern piece in his arms - it was the only token left by his master, and it was also the target of the family's enemies.
He was ridiculed by school beauty Su Muyan's best friend for "brainless work", and was pushed down and humiliated by a wealthy second-generation owner, but he endured it. It wasn't until his colleague Fatty Wang was bullied that he showed his hands and grabbed the opponent's ankle to make him kneel in pain. No one knew that this security guard, who even carried couriers carefully, could knock down gangsters with three punches and use Qingyun Sect's "Flowing Cloud Palm" to repel martial arts disciples.
When the traitors of the Black Crow Society came to the door, and when the whereabouts of the master came to light, Lin Chen no longer hid. Under the streetlight outside the security booth, he clenched the bronze dragon-patterned piece and said, "If you want to touch the person I protect, ask me first with my fists." From then on, the "ordinary security guards" of Boyue Mansion became the hidden dragons that were least dared to be messed with in the urban arena.
