Crescent Moon Gu

The immortal killer move peerless crescent moon slash uses the rank seven crescent moon Immortal Gu as its core, with two rank six Immortal Gu as support. The move demands extremely high immortal essence and burdens the mind heavily; a single Gu Immortal cannot display its might, so two Gu Immortals must activate it together. Fairy Ao Xue and Fairy Ling Mei activate it together and condense a blue crescent moon the size of a water jar that slashes open a stretch of the saint regional wall about seventy-six steps long. ^{ch. 710}

Fairy Ling Mei of Heaven’s Envy Manor and Fairy Ao Xue have control over the rank seven crescent moon Gu. Cooperating, they can unleash the killer move peerless crescent moon slash, a signature move of Heaven’s Envy Manor. During the hundred days battle that collaboration is a large threat to Shadow Sect, and almost all the Gu Immortals there are injured by the move to varying degrees. ^{ch. 923}
