Lin Feng is a pork vendor at the market in a village in the city, and he can use a bone chopping knife better than a boxer in a martial arts gym. No one knows that he hides the ancestral "Bone-Splitting Fist" boxing manual, and no one knows that he is the only surviving descendant of the ancient martial arts family that was wiped out five years ago; Zhao Lei is a sorter at the scrapyard next door, breaking steel bars with his bare hands like chopsticks, and always carrying half a rusty "Suppression Order" in the pocket of his overalls—— The two were supposed to be "low-level ants" in the city, but they were forced to bind due to an "underground fighting".
In the eighth year of the revival of spiritual energy, "evil bone rats" that devour warriors are hidden in the narrow alleys of urban villages. The compressors in the scrapyard have become tools for evil bone cultivation. Even the rent collectors wear "martial arts glasses" that can detect energy and blood. When Lin Feng awakened the Lin family's bloodline to save Zhao Lei, and when Zhao Lei's martial arts suppressing order split the evil cultivator's bone array, two names suddenly appeared on the "Bone Martial Arts Association"'s hunting list: "Catch them alive! The Lin family's fists can refine the 'Martial Bone Pill', and the Zhao family's order hides the martial arts suppressing array!"
During the day, they were greasy vendors and sorters; late at night, they practiced boxing on the rooftop and slayed evil spirits in the sewers. The neon lights of the urban village reflect not only the dilapidated brick walls, but also their clenched fists - trying to carve a path to heaven for the warriors in the mud!
