Lilith was somewhat surprised at Atlas' Knowledge. Even though she herself allowed him to use her Grimoire to study up, he hadn't expected her to remember all the spells so well.
However, she could also see that he was right. His words made sense as well. If she used the spell that he wanted, then it was indeed possible.
She still had to convince the other side with her words to help her in creating a linking formation which wasn't an easy task since she wasn't that well liked by the other Witches, but it still was possible to some extent.
"Can you pull it off?' Atlas asked, seeing Lilith lost in some thoughts. "I can, but... It will not be easy. And the possibility of success is really low. For a moment, I might be able to convince all the Witches to come to meet me, but convincing them to make a link formation for me near their base is going to be pretty hard."
