Twelve years ago, a league of XX masters joined forces to raid Muxia Manor, the foremost manor in the martial world. The manor's master, the Heavenly Sword of Tianya, An Tai, fought to the death, and his only daughter, An Ning, perished.
The Qin family inherited Muxia Manor. Its young master, Qin Nanzhao, spent ten years training in swordsmanship. At last, he defeated the assembled masters at Huashan and restored Muxia Manor's reputation.
The same year as the Huashan sword tournament, a man in a green robe appeared out of nowhere and slew the villains who had taken part in the league's raid. Qin Nanzhao pursued him and discovered that the Green-Robed Swordsmen were a pair of fellow disciples, with close ties to Muxia Manor and to Qin Nanzhao himself. As Qin Nanzhao and the Green-Robed Swordsmen investigated, the mastermind behind the manor's destruction gradually came to light.
It turned out that the destruction of Muxia Manor was only one part of a vast conspiracy. Even the collapse of the Western Expedition General's household had been orchestrated by the same person. For years, the mastermind had laid his plans, carrying them out one step at a time.
When the dust settled and the truth was laid bare, a duel that would determine the fate of the realm was about to begin.
Can those who sacrificed the innocent to fight evil be forgiven? Should someone who betrayed the person they loved after being deceived be forgiven? Can the tangled grudges between two generations be unraveled by the peerless Qingjue Sword?
