How much power did it take to kill a Void Step Demon King?
Su Che had not thought it through.
Yet the instant he truly saw the Ironback Dragon King, an almost uncontrollable killing intent rose within him.
This should not have happened.
They were meeting for the first time. He was merely a Void Step-level Demon King, smiling and amiable, looking exceedingly easy to talk to.
He should not have harbored killing intent toward such a figure.
By now, his state of mind had long been as still as a calm lake, unlikely to stir even the slightest ripple.
Almost in the very next instant, Su Che sorted out his thoughts and found the source of that impulse.
That impulse came from the Earth Book, from the depths of his own mind.
Ever since the battle at the Earth Official Immortal Abode, the Earth Book had quietly hidden within his sea of consciousness, fused with the bright moon transformed from the Yin Mountain Nether-Cavern Treasure Register.
Such a treasure of fortune and merit had lived up to its origins. Joined with his Dao Foundation, it had undergone no change whatsoever.
For cultivators, no change was itself the best change.
This killing intent came from the Earth Book. It was the disgust this treasure, which had witnessed the founding of the Ancient Heavenly Court, felt toward the path of the Primordial Demon Gods.
The Primordial Unity Saint-Annihilating Dao upon the Ironback Dragon King was so pure that it enraged this artifact, which had endured the bloody storms of that era.
That anger lasted only an instant, yet it seeped into Su Che's mind as well.
Within the Hundred-Thousand Mountains, the remnants of the Primordial Demon Gods quietly survived, passed down their legacy, and waited to make a comeback.
