The next moment, a terrifying chill arrived in an instant.
But compared to its attack, Mu Rufeng was obviously faster.
In an instant, the entire gloomy palace was brightly illuminated by a fiery red glow.
A giant fireball, twenty zhang in diameter, appeared before Mu Rufeng.
The attack hit the fireball, and then disintegrated into ash.
"Wow, the fireball from the Explosive Flame Technique is really huge," Mu Rufeng commented before he hurled the Fireball Technique out.
"BOOM~~!"
A violent roaring sound erupted.
The entire palace was engulfed in flames, and the powerful aftershock cleared all the black matter surrounding it.
Mu Rufeng stood very close but did not dodge, as his Flame Armor could reduce most of the damage from the flames.
Still, Mu Rufeng backed away because the ground had collapsed.
The earth was shaking, the entire Dragon Palace was vibrating, giving the impression it was about to crumble.
