Lin Dong transmigrates into a world that blends multiple Hong Kong movies. From the start, he takes the fall for someone else and spends nine years in prison. But when he gets out, his former benefactor betrays him. Fortunately, he awakens the Sign-In System. From then on, he takes decisive action, clears every obstacle in his way, and eventually rules the Hong Kong underworld. Everyone respectfully calls him Uncle Dong.
