Backtrack Gu

Fang Yuan activates one beside a vanishing shadow leopard corpse while investigating a battlefield with Hei Lou Lan. ^{ch. 719}

Appearance

It has the appearance of a crystal sphere. ^{ch. 719}

Form and rank

It looks like a crystal sphere. It is a mortal Gu. ^{ch. 719}

Effect

When Fang Yuan activates it, the Gu displays a blurry and mute battle scene. Against rank six and above targets with immortal or desolate beast bodies, dao marks restrain its investigative ability: the scene stays extremely blurry, breaks off intermittently, and leaves identities hard to confirm. ^{ch. 719}

Cost and supply

After a dozen breaths of forcing an image of that Gu Immortal level battle, scorching smoke rises from the Gu and the scene vanishes. That use kills the Gu. Fang Yuan stores the scorched corpse in his immortal aperture to remove traces. He had been gathering Backtrack Gu from treasure yellow heaven and held only fifty to sixty. In peaceful times that stock is already hard; during the chaotic war of the regions the Gu is widely used, hard to buy, and often must be produced for one’s own use. Hei Lou Lan does not know its name at first. Worms like it are rare Gu of another path, which fits her strength path focus and limited knowledge of uncommon time path Gu. ^{ch. 719}
