—So this was the truth of Artificial Soul... Ordinary people had no obsessions, no wishes or ambitions, nor enough strength to condense a soul. That was why they needed an external "core" to condense a sufficiently enduring soul and become phantoms!
—That peculiar plague was essentially an experiment involving Brain Attachments, and the Grand Duke's medicine was very likely a drug that inhibited the active development of Brain Attachments! Or rather, a drug that allowed the Brain Attachments to focus on shaping souls!
—So that's how it was. I understand now. This Brain Attachment must have originated from the Redwood Natives. The Great Shaman's parasitic ability came from an ascension potion created through the Magic Beast transformation of Brain Attachments. Blazing Flame Lands obtained the relevant information from the Great Shaman's side, and because this had only happened within the past two years, the Grand Duke's experiments had accelerated only recently!
And that was precisely why Blazing Flame Lands wanted to obtain the Brain-Eating Worms! Beyond the Brain Attachments inherited from the Redwood Natives, they wanted an even more primitive and more powerful form of Brain-Eating Worm!
Everything made sense now. Ian connected all the clues into one thread.
Blazing Flame Lands, the Spirit Cognition Institute, and the Grand Duke had established research facilities in Awak Domain. Their research results were independent of one another, yet they shared something in essence.
And this was surely Grand Duke Solin's goal. From the beginning, he had borrowed the power of the Empire and Blazing Flame Lands to complete his own plan.
And Artificial Soul—or rather, the existence of the "Brain Attachment"—was absolutely a crucial part of that plan.
"Interesting. It seemed that the angriest party right now was probably not the Spirit Cognition Institute or Blazing Flame Lands, but Grand Duke Solin."
