Although Annan wasn't quite certain, Ingrid had been gathering so much demon blood for a specific purpose.
But she was definitely scheming something.
After all, her Elemental Power gave her the chance of "guaranteed godhood"... but it also restricted her from taking direct action.
When Ingrid acted, it had to be at the moment when the dust settled. Under other circumstances, she could only maneuver through plots and curses without showing her face.
Now, she couldn't possibly devote all her energy to hinder Annan's progress—because even if she desperately troubled Annan, he would certainly grow stronger.
Once Annan reached the Truth Rank, it would be akin to checkmating Ingrid.
At that point, no matter what Ingrid did or how she struggled, it would be useless.
So, she would definitely race against time with Annan, continuing to figure out how to complete her ritual of the "Eternal Maiden."
