The Great Sun Furnace Sword, a Tenth-order Divine Weapon, is forged from Red Flame's Primal Copper after being subjected to countless hammerings and smelts in the Heavenly Gang Star Flame. It has an attack power of 6500-6900, flight speed of 4000-4400, and attack speed of 4200-4800. It requires a user of the 132nd level with a Fire Virtue Real Body or a Fire-element Immortal Bone, which can lower the usage requirement by 10 levels.
Attached to it are Elder-Level Forbidden Art Heaven Furnace Forging Gold True Method and Elder-Level Forbidden Art Three Yang-Qian Heavenly Ding Fire Net. Currently, it has twenty layers and can be upgraded through cultivation.
As a characteristic of the Tenth-order Flying Swords, the weapon can summon the Ancient Fire Dragon to form a hundred-mile range of raging flames, which enhances the power of all fire magic spells by 100% within the range.
