The area surrounding the fight was still devoid of world energy due to the Doom Blast but placing the exit point nearby was enough. The two Divine Beasts-Eldritches exploited gravity to bolster their already astounding speed and reach their target like a living missile.
Bolts of silver lightning covered Eycos' whole body while Kigan's was aflame due to his bloodline ability, Molting Essence. It turned the Black Phoenix into a living mass of Origin Flames and made him immune to physical attacks.
The Garuda and the Black Phoenix were separated only by a few meters, the energy of one seeping into the other. The silver bolts of Life Maelstrom turned red while the edges of the Origin Flames burned white, slowly merging into one.
The Life Maelstrom and the Origin Flames fused, turning the Phoenix and the Garuda into a single mass of living plasma.
