During the transformation process, Milton Cheney's consciousness was in a state akin to complete emptiness.
During this period, Milton Cheney could not perceive his environment, but he could actively sense the changes in his own body.
In fact, from the moment this transformation began, Milton Cheney had been continually aware of the changes in his body.
However, a demon's transformation was merely the growth to a critical point, and not an instance of sudden, drastic change.
The changes between a second-level demon and a third-level demon had already occurred during this process.
This was somewhat similar to the growth process of humans from childhood to adulthood.
Humans can clearly know when they have reached adulthood, but if you ask whether there is a distinct feeling at that instant of maturity, it seems there isn't much of one.
The transformation of a demon was somewhat similar to this.
