The ritual of the hunt

"Just how did it do it?" 

This question was a lot more valid than it appeared to me when I first thought it out. 

Earlier, I just assumed that there existed some sort of AI subroutine that simply fit into the nervous system of those beasts, allowing the AI to manipulate them once those beasts absorbed a sufficient amount of the infested Qi. 

But now that I look back on this idea… It didn't make the slightest sense!

'How could an AI, a spiritual energy-anchored consciousness infuse itself into the flesh and bone of those beasts to make them do its bidding?'

A question seemingly with no answer… But as proved by practice, a feat that was certainly possible - because it happened. 

Yet, even after taking a moment to think about it, any form of complex and wholesome answer simply eluded me.
