Taiyi Zhenren prepared a fire-tipped spear for Nezha’s lotus body, and Nezha entered the Investiture battlefield on the wind-fire wheels with that long spear. Its point carried fire, and he used it in turn with the Qiankun Ring and the Red Armillary Sash.
Red Boy on the pilgrimage road also carried a fire-tipped spear of the same name, and used it with the samadhi fire outside the Fire Cloud Cave against Wukong. Each spear belongs to its own owner; it is not one weapon that passed from Qianyuan Mountain to the Fire Cloud Cave.
