Desperate
The mysterious space inside the white lotus stored the souls of all those who died in the vicinity of its wielder after being absorbed.
All the souls that had been stored in this space had a certain attribute that distinguished them from the other souls.
Mainly, this characteristic divided them based on the race or species they belonged to prior to their deaths.
When the live humanoid-shaped tree was destroyed by the group of mercenaries, its soul was naturally devoured by the white lotus.
Furthermore, when Adam noticed the faint characteristic emanating from this soul, he could confirm beyond a shadow of a doubt that it belonged to a human!
The reason for his confidence stemmed from the fact that of the souls that he had absorbed in the past, the vast majority of them belonged to powerful humans from the greater universe.
