Arm Bone Wings Gu

In the second white bone hall on Bai Gu mountain, Fang Yuan and Bai Ning Bing find Arm bone wings Gu held in one of three white bone pillar hands beside Ribcage Shield Gu and Flying Bone Shield Gu. Pillar text limits the inheritor to one choice among the three. Fang Yuan leaves it and takes Flying bone shield Gu instead. ^{ch. 222} Bai clan pursuers later recover the left arm bone wings and rib shield Gu and stow them. ^{ch. 223}

Form and rank

Bai clan members note that the two Gu left on those pillars were rank three Gu worms. ^{ch. 223}

Effect

Activation grows a pair of bone wings at the forearm area. Waving those wings increases movement speed slightly, and most importantly increases attack speed. Fang Yuan judges the Gu useless for him because he already has Jumping Grass Gu and does not fight close combat. ^{ch. 222}

Path

The white bone inheritance lists it with Ribcage shield Gu and Flying bone shield Gu without naming a cultivation path for it. ^{ch. 222}
