Shane also had some vague memories of this matter.
He remembered that it was either Ai Yi or Nien who told him that members of the Old Demon Clan Faction had once attempted to resurrect the Demon King but had failed. That was why they shifted their efforts towards creating a second Demon King and concocting the plan to fabricate the Seventh Demon.
"The Demon King cannot possibly be resurrected," Laischa said solemnly, "Her chances of resurrection have already been severed from the realm of causality by the Supreme God Ominis. Unless the Supreme God itself is willing to let go, there is no possibility of the Demon King coming back to life."
It was under these circumstances that the people from the Old Demon Clan Faction felt such despair that they recklessly pursued the creation of a new Demon King.
