Rank and use

Cited text names Gentle Wind Gu as rank eight and treats it as a Gu Wu Yong can use in that clash, separate from the two rank eight Immortal Gu Wu Du Xiu left him. It does not describe the Gu’s own effect beyond that judgment that it alone cannot break the purple blood river formation. ^{ch. 1341}
