Wudang's Sole Worrisome Sword (무당일우검=Mudangil Ugeom, 武當一憂劒), one of the Three Heroes during the Chaotic Era of Factional Wars. He is an Ancestor of the Wudang Sect of the Nine Great Sects.
The one who secluded himself in the depths of a shaman's profound and remote inner sanctum, dedicating his entire life to the pursuit of mastering the Taiji Enlightened Sword Technique alone. Though veiled by the Martial God's divine status, when he swung the sole sword in the Chaotic Era of Factional Wars, the enemies fell like autumn leaves in a gust of wind.
