That spark of fire flared to life atop the Evil-Slaying Saber. As the long saber whirled at high speed, friction with the air made its dark-black blade glow a dazzling red.
The Zhanmadao had originally been forged by an ordinary blacksmith, but after being modified by the system, no one knew what had happened to its material.
