As a terrifying wave of Demonic Energy erupted from the plaza within the mountain, Qin Tian and Mohe Tian exchanged a glance. Qin Tian slowly said, "We can't stop two Heavenly Demon Emperors. Let's minimize the casualties as much as possible!"
Mohe Tian also knew full well how powerful these two Heavenly Demon Emperors were. Although the Nine Corpse Heavenly Demon Emperor had only just awakened, the Outer Domain Evil Clan had clearly come prepared. The sacrifice of three Xuan Mo Emperors had directly awakened the Nine Corpse Heavenly Demon Emperor.
That violent aura likely possessed the strength of an early Saint Grade Heavenly Sovereign. With another Heavenly Demon Emperor eyeing them hungrily at the side, Qin Tian and Mohe Tian could do nothing about it!
"Ho ho ho!" A harsh, grating sound came from the 'Heavenly Emperor's' mouth. The 'Heavenly Emperor's' eyes had fully opened, pitch-black within and filled with a terrifyingly evil aura.
This was the 'Heavenly Emperor' whose body had been taken over by the Nine Corpse Heavenly Demon Emperor. "After thousands of years, I've finally emerged. Heavenly Emperor, in the end, you still lost!"
The Nine Corpse Heavenly Demon Emperor immediately threw back his head and laughed. Back then, he had led the Outer Domain Evil Clan in descending upon Tian Luo Continent. He had originally thought it would be a one-sided slaughter, but he had never expected to encounter such a hard bone as the Ancient Heavenly Palace!
Although the Ancient Heavenly Palace had few Heavenly Sovereign experts, with the Heavenly Emperor standing guard, the entire Ancient Heavenly Palace had held back all the Outer Domain Evil Clan forces led by the Nine Corpse Heavenly Demon Emperor.
The Nine Corpse Heavenly Demon Emperor himself had even had seven demonic souls severed by the Heavenly Emperor.
