Bab 104: The Fourth Floor (part 3)

Seated on a bench he had quickly crafted using the fallen tree, Aito absorbed one soul core after the other. 

The absorption process was the same as absorbing mana beads. Either eat it or drain it. The empty core would then disappear because what maintained its physical state wasn't there anymore. 

Each time he sucked in the mana and soul, he felt that something was added to his own core. After emptying the fifteen cores that were his share, he could feel that he was almost at his limits. It was akin to a filled stomach, if he were to abuse it, his soul core would burst into pieces. 

He needed to give his soul enough time to digest the goblins' souls. Inside his bosom, the goblins' souls were trying to fight a pointless battle, running away from the human soul sucking their life.

Well, there were already weakened because of the death of their body, so there was nothing they could do about it. Aito's soul only needed time to steal their life force.
