Dense soul energy flooded into Kevin's mind as the core of his sea of consciousness—namely the black variant of his third eye, twitched slightly and began to suck in the immense influx of energy. Kevin's mind immediately cleared up as a refreshing feeling assaulted his senses in passing while the nutritious soul passed by his exhausted mental power.
The third eye absorbed the majority of this energy and released feedback equivalent to perhaps a fifth of this energy, which was no different from the scrap metal discharged after tempering a fine body of steel, but this scrap metal greatly benefited Kevin as it helped stabilize, purify, and fortify his existing mental power even more.
If Kevin did the calculations correctly, this was equivalent to the souls of a thousand ordinary humans at the very least—exceptionally healthy ordinary humans per se.
