After learning about the otherworlder's situation Elena asked Lya what she wanted to do. Hearing her question Lya replied that for the time being, she was going to use that person as a knowledge bank and would try to improve their own biological knowledge at the lower level. As she was the goddess of life and death and Alreuni also had concepts related to biology and nature, both of them were quite well suited for this field.
As for invading that low level world, Lya did intend to make a visit to that place. But if that world was a normal peaceful world then she would not harm it too much and would just collect some knowledge as compensation. But if the world was an evil world that had the intention of parasitizing other worlds then Lya would not mind destroying it outright.
