Also known as the Northern Spear, it is the sharpest spear in the world and bears the heaviest meaning for Tianyao. It measures five chi in length, about the same height as Pei Nai. The spearhead has blades extending seven cun on either side, razor-sharp. The pale silver mount bears raised patterns, the shaft is coated in black, and near the base of the blade are engraved golden characters reading 'Loyalty in Blood.' It was enshrined in the Pei family ancestral hall.
