Once a cowardly boy who was bullied by others, Li Yu sowed the seeds of revenge and becoming stronger in the humiliation in the alley of the third grade of junior high school. After spending the summer practicing physical fitness and studying martial arts, he returned from his first year of high school completely transformed. He breaks down bullying with ruthlessness, gathers brothers with the bottom line, protects the weak and establishes rules. He fights step by step in the disputes in the dark streets around the campus, transforming from a lonely young man to a boundary-keeping boss. This is a journey to the rise of the underworld about resistance, growth and perseverance. From the dark alleys in the west of the city to the global battlefield, the down-and-out lawyer and his top teammates form a cross-city joint defense to sweep away gangs, break drug networks, and fight transnational criminal groups, using justice as the blade to protect thousands of families!
