The Merciful Sword and the Withering Blade

[A classic wuxia story, written in the spirit of Jin Yong] Wherever people gather, there is a martial world. Grudges all begin in the heart. Push me too far, and try taking these three blades!

One is a white-haired youth suffering from a grave illness, with several schools' secret techniques at his command. The other is an outcast servant-born son, shunned by all, who creates peerless saber techniques from just two words on a stone tablet. How will these two hard-luck brothers-in-arms unravel decades of plotting by an evil cult and save the martial world, step by step?
