This was clearly a case of accelerated "psychic corrosion."
Cui Si continuously observed this process, once confirmed that the corrosion had been completed, she used magic on the spot to re-integrate the spiritual projections of the two little players.
The process was not difficult.
Because the psychic projections of the little players had not been destroyed from an existential perspective. They were just transformed from solid to energy state, so re-converting them back was all that was needed.
With Cui Si skillfully manipulating psychic threads, Cheche and BullBull's bodies reformed. They were like before, but now their eyes projected crimson red spots, and vampire canine teeth protruded from the corners of their mouths.
"Eeeeek! Something's different!"
Looking at his unusually pale hands, Cheche exclaimed:
"Why has my vision changed? It feels like infrared detection, and it's so uncomfortable! I hate the sunlight outside the house - it's burning me. I'm going to burn up!"
