Lu Ren saw Emperor Lord Guiyi enter the demon hall. Without hesitation, he leaped forward and slashed with the Chaos Ancient Sword in his hand.
Sword light flashed in rapid succession. Before Ghost Ark and the others could react, it pierced their foreheads and killed them instantly.
After killing Ghost Ark and the others, Lu Ren activated Void of Destiny, passed straight through the demon hall, and concealed himself.
The demon hall was pitch-black and eerie. Surging demonic light crisscrossed its walls, while layer upon layer of formations filled every corner.
If he had not used Void of Destiny to render his fate utterly void and leave the formations unable to sense him, he would probably have triggered them at once.
Lu Ren did not dare advance. Instead, he activated his Chaos Eyes to investigate.
As his perception reached farther ahead, he found a massive altar in the depths of the demon hall, radiating an extraordinarily dense aura of blood.
Four elderly members of the Demon Immortal Clan stood around it.
Emperor Lord Guiyi stood beside the altar. In his palm floated a crimson drop of essence blood.
That drop likewise radiated a dense aura of blood. It held the majesty of the dragon race, and faintly, a Dragon's Roar could be heard from within it.
"That's Ancient True Dragon Essence Blood! Lu Ren, if you get that drop, you can step straight into the Dragon Transformation Origin Realm!"
The voice of Immortal-Smiting Iron rang out.
"Emperor Lord Guiyi really does have plenty of treasures on him!"
A brilliant gleam flashed in Lu Ren's eyes.
Emperor Lord Guiyi handed the Ancient True Dragon Essence Blood to one of the elders and instructed him, "Once this emperor enters the altar, activate it and put this drop of essence blood inside. Understood?"
