Golden Crystal Sand

A rare fifth-grade material that was actually half transparent. Each speck was a cube. At the center of the cube was a hair thin golden thread. Zuo Mo found an abundant supply of it in the core region of the Ancient Battlefield where the Sun Tribe fell. Since they cannot pack it all, Zuo Mo instructed the Golden Crow Camp to forge all of it to fifth-grade flying swords and ling armors for the Vermillion Bird Camp.
