Rainbow Breaking Sword Technique.
This sword technique originally belonged to the fire attribute category.
Now that Ye Qiubai had reached the Realm of the Flame Origin, using the Aged Golden Sword Case to execute Rainbow Piercing the Sun barely required a significant focus of his mind to unleash his full strength.

Not to mention, with the enhancement of the Flame Origin and the divine Xuanhuo Tree, even just employing the Aged Golden Sword Case alone was enough to cause Commander Pang to break out in cold sweat.
At the same time, within the Sword Domain, the Endless Sword Intent sought out Commander Huang.
Commander Huang's expression changed slightly; the sword qi that carried a thread of the sword origin, along with the Ash Fire, also made it impossible for her to extricate herself at once!
