A fierce battle at Chujiang Ferry led to an unexpected encounter between the swordsman Su Ye, who was hiding in the city, and Lin Qinghan, the descendant of Jueqing Valley. The former carries the mysterious iron box entrusted to him by his master before his death, which contains key clues to the collapse of the Yanyu Sword Sect thirty years ago; the latter goes to the appointment with a bronze token and is on a mission to uncover the unsolved cases in the world. When the two long swords clashed for the first time under the setting sun, they not only repelled the Black Wind Hall killer who was chasing the iron box, but also stirred up the long-standing turmoil in the world.
The dark iron box was opened, and the yellowed sheepskin map pointed directly at Soul-Desolating Cliff - the bloody place where three hundred innocent souls were buried. Su Ye's Liuyun sword technique hides the unsaid past of his master, and the shadow of Lin Qinghan's Hanyue sword reflects the secret relationship between the sect and the old case. The two walked together, chasing from the reed swamp to Qingshi Town, and from the ancient tombs in the deserted villages to the cliff abyss. Along the way, there were not only the undead pursuit of the Black Wind Hall, but also the layer-by-layer layout of the mysterious organization. Every flash of sword and shadow is piecing together the truth: What kind of secret treasure does the Yanyu Sword Sect hide? Is it a power struggle or a conspiracy behind the massacre? Master Su Ye's true identity, and why is it inextricably linked to Jueqing Valley?
When the fog of Soul-Desolate Cliff gradually lifted, they discovered that the serious case was shrouded in a shocking scam that spanned thirty years, and they had already become the most critical piece in the chess game. Should he stick to morality and reveal the truth, or should he follow the rules of the world and protect himself wisely? Every resonance between the green steel sword and the sapphire sword is asking the most fundamental proposition of the martial arts world.
