La mejor espada

This is Yanqing's companion mission, and requires you to reach Trailblaze Lv 34.

This achievement has no cultural references in the English and Chinese versions. Jingliu and Yanqing are sword users, with the former once hailed as the venerated sword master of the Xianzhou Luofu and the latter being a swordsman gifted with the art of swordplay and war who has a prodigious interest in swords. You could say that both are "Master(s) Among Swords."
