Devour Soul Gu

Fang Yuan later wants devour soul Immortal Gu more than Soul Search when looting Southern Border captives, because Shadow Sect once possessed it and it would make extracting those Gu Immortals’ souls from their bodies much easier than his then methods. At that stage Yang Ku has three soul path Immortal Gu, and devour soul Gu is not among the next two after Soul Search. ^{ch. 1610}

Great thief ghost hand later steals devour soul Gu from Yang Ku as a soul path Immortal Gu, and Fang Yuan’s time path clone treats it as the core needed to use the killer move devour soul. After the wisdom refinement formation refines it, Fang Yuan takes devour soul Immortal Gu, activates other Gu with it, and draws Yang Ku’s soul out. ^{ch. 1790}
