From a corner where he was cornered by the school bully to ruling the underworld order of the entire campus, Zhao Xuanhe befriends Cao Si, Zhang Mangke, and Shang Wenjian. Leading his brothers through blood and fire, he earns respect through ruthlessness and wins people over through loyalty, transforming from a well-behaved student into a campus boss whom the whole school fears. But the road of the underworld stretches far beyond the school gates, where an even deeper abyss awaits. The Canglong Hall, watching hungrily from outside; the ruthless Fierce Tiger Gang; and the Gray Crow Society, entrenched in its own territory, surround them on all sides. Schemes, fights, betrayal, and plots never cease.
Amid flashing blades, brothers live and die together; through rivers of blood, their loyalty endures until death. Zhao Xuanhe, Cao, Zhang, and Shang lead their brothers out of the campus and into the turbulent criminal underworld. From street brawls to clashes between rival factions, they rise from nobodies to underground kingpins who can shake the world. They hold fast to their original ideals, yet cross lines they never thought they would; they suffer grievous wounds, but never bow their heads.
