In the final years of the Warring States period, the Seven Kingdoms wage fierce war, and the flames of battle spread across the Central Plains.
In Handan, the former Qin hostage Zhao Zheng, who once depended on others for shelter, takes the name Zhao Wuji and enters the Mohist School at the age of seven. After half a year studying together, five masked youths sit in one hall, debating how to govern and what brings a state to ruin. Azure Dragon seeks laws to strengthen the foundations; White Tiger values power and strategy to maintain balance; Black Tortoise hopes the kingdoms can coexist; Qilin pursues political cunning and adaptability. Only Zhao Wuji, still a boy, vows to unite the Six Kingdoms, standardize roads and writing, and end the chaos through unification. The Five Crowns rest upon their heads, their master's teachings echo in their ears, and beneath their youthful ambition, the fate that will one day make them enemies on the battlefield has already been set in motion.
Deep in Purple Mountain lies another fate, unknown to all.
Bearing the blood feud of his family's brutal murder, the young Zhao Zhenghan trains alone in the mountains, studying the Yang family's Heart-Calming Art. Every time he sinks into meditation, the bloody memories of his parents' deaths surge back, and a cold, eerie whisper rises in his heart, tearing at his soul day and night. One master and two disciples, one mountain and one city: on one side is the grand vision of scholars striving to rule the realm, on the other, the bitter sea of a heart demon trapped in the past.
The flood of the chaotic age rolls ever closer. Each youth follows his own path, some bound for the halls of government, others trapped by their inner demons. The course of history is already laid out, and their choices will ultimately stir the surging tides of Qin's rise.
