The process of Spirit Core absorption was quite simple and rather relaxing. By grabbing a core, I simply closed my eyes and absorbed its energy, letting it flow through my hand and into my body. The Spirit Core would then turn colorless and break down into glass sand, which would simply disappear afterward.
I repeated this process over and over again, until I found a good way to do it en masse, by stretching my hand into a giant wooden hand and grabbing dozens of cores at once.
FLUOSH!
Like this, I could absorb dozens at a time, letting a lot of energy flow through me, and quite honestly, it felt really amazing.
Until finally, I felt I couldn't do it anymore, as one of the Spirit Cores simply would not turn gray no matter how hard I tried.
"Phew, I think I'm done for today~"
