Mystery 1900: Beginning in Chinatown

Traveling through Chinatown in Jinshan City in 1900, I became a gangster who owed the Tang Kou three hundred foreign dollars. But something's not right about the world— The plague is raging, the priest chants cult scriptures under a gas mask, and the mechanical golem carries a fuel can and raises a spray gun; The mantis boxer stretches out his abnormal fingers, and the compound-eyed angel's scale wings shine with light; The entrance of the hall, the rain alley, the bloody white blade; Western, Gun Bore, Noon Showdown; Scientific fantasies, five secret arts, remnants of heaven, world war, indescribable things... When the engine and the chain saw roar, and the fantasy and weirdness dance together, between the diesel engine and the gods, how can a street kid find a way out?
