Wandering the jianghu with a blade and wine, where beauties’ grace is filling one’s mind.

A youth, saber on his back and wine gourd at the waist, strides forth, yet the jianghu of his heart seems only more elusive;

With each flipped page of the Tome of Troubled Times, decades of nights soaked in rain pass over the jianghu.

As he suddenly turns to look back, he finds that the mortal world has shattered in his wake.
