Just now, Marquis Bamboo Sword unexpectedly teleported behind him and slashed a terrifying sword.
"Fire Emperor Flag, sweep through the All Heavens!" The Fire Emperor quickly leaped out of the battle circle, and with the rotation of the Divine Light, the flames around him transformed into battle armor, enveloping his entire body.
An ancient aura emanated from the armor, with hints of blood-red patterns floating; this was the battle armor used by a past Fire Emperor, even if the original owner had fallen, it still possessed an invincible might.
For supreme overlords like them, when their cultivation can no longer advance, to enhance their battle power, they can only rely on refining divine abilities or powerful divine weapon treasures.
However, powerful divine powers are inherently scarce, and wanting them to align with one's own Tao is even more difficult. Moreover, cultivating a divine power to the Great Completion Realm takes an exceedingly long time.
