After enhancing the White Nightmare Emperor with the effect, Ye Qingzi immediately had the Darkflame Sky Demon assign the Nightmare Demon Ruler the Darkfire attribute.
The Nightmare Demon Ruler was already an Invincible Emperor, having been stuck at this peak for countless years, his strength almost unmatched among Emperors!
At this moment, the support from the auxiliary effects allowed the Nightmare Demon Ruler to thrive even more comfortably, handling the assault of three or four ordinary Peak Emperors with no stress at all.
Ning Dong's expression soured; he had already summoned three Peak Emperors. These three Peak Emperors were surrounding the White Nightmare Demon, yet they could not subdue it. As the effects of the Darkflame Sky Demon were added, the aura of the White Nightmare Demon grew even stronger, and his three soul pets were simply not up to par anymore.
