He unfurled the map. The map's material was peculiar, flexible to the touch, and did not decay despite the years. With deep brown lines, it delineated an extremely complex, three-dimensional network of earth veins, mountains, rivers, mineral veins, cavities, spirit eyes, and even some special energy nodes and architectural ruins detailed comprehensively. At the map's center lay the area where the Dark River was located, covered by a conspicuous sigil of three circles, with ancient script beside it stating, "Nine Netherworld Seal Formation Eye · Celestial Demon Root Command Post."
At the map's edge, near the southeast, beside a complex node marked as "Earth Veins Convergence · Yin Sha Eye," there was another slightly smaller but equally conspicuous mark resembling a strange plant with nine leaves, its top holding a star. Ancient script next to it read: "Purifying Spirit Ancient Wood · Remnant Spirit Root Suspected Point."
