The materials required to refine the magical treasures recorded in the Hundred Poisons True Scripture are quite rare and hard to come by.

Little Chick was instructed to find the materials needed for the Nine-Rank upgrade of the Deadly Centi-Poison Cold Light Barrier. Having spent great effort through the Qing Emperor Alliance, the majority of the materials were finally delivered, only lacking the Profound Ginseng Ice Serpent Essence Blood.
