Sheepskin map

Young Thieving Heaven searches a Gu Master corpse in an underground hole and finds a sheepskin map in the clothes, with no Gu worms left on the body. He judges that the map must have existed for a very long time. Its focus is his clan’s small oasis, with several Western Desert words; most are blurry, and he barely reads phrases including land of buried immortal, inauspicious, and curse. He wonders why a strong Gu Master used a sheepskin map instead of information path Gu worms, and notes it was sewn into the inner layer of the clothes. ^{ch. 1493}

Sha Xiao stitches the sheepskin map into young Thieving Heaven’s clothes and orders him to throw that clothing into the oasis pool. ^{ch. 1509}

Fang Yuan concludes that the sheepskin map is definitely an immortal material, processed so it could not be detected, and that it immediately reacts after soaking in the pool water. He also judges that the small oasis was tampered with to form a Gu refinement area. ^{ch. 1511}
