In Longyuan City, gangs are everywhere, the strong prey on the weak, and ordinary people at the bottom suffer constant oppression.
The meticulous Lin Shen gathers nine brothers, each with their own special skills, and forms the Shadow Alliance.
With no superpowers or lucky breaks, they rely entirely on their wits and passion, starting near the schools in the south of the city and taking on one criminal gang after another.
They don’t use violence to bully others. They fight only to protect the weak, breaking through with the blades in their hands and living by the justice in their hearts.
From an unknown little group, they fight their way up step by step to become a citywide force, vowing to carve out a just place for the people at the bottom of Longyuan City!
They wield their blades to protect the people, and uphold justice with every strike. Brothers stand shoulder to shoulder as they fight their way to the top!
