Therefore, Kael formed a comparative screening group, with the same type of monster corpses being directly transformed into Bloodline Essence by the Rangers' Slimes and absorbed, the related changes that occurred before and after in the Slimes constituted one group.
The commonalities and individualities that the Bloodline Essence of the same monster group exhibited in different Rangers' Slimes formed another set of comparisons.
The commonalities and individual features between absorbing monsters and Bloodline Essence constituted yet another group.
The similarities and differences between various races directly absorbed by Aister and those acquired after consumption by ordinary Slimes constituted yet another group.
…
In short, both the common ground and the differences needed Aister to assist Kael in deducing and judging, in order to ultimately find the key elements hiding the "racial expertise."
