If this was Ainsley's usual strength, her charm would only make the people who could create domains and those ancestors feel that Ainsley was cute and they would have more good feelings towards Ainsley.
But it was limited to that.
It was impossible to brainwash or control the target with her current charm ability level!
Of course, that was before Asmodeus came.
[You don't need to worry about exhausting your energy either. All of this will only suck my own evil energy and not yours. You only need to control your ability and attack bravely.]
Asmodeus was only afraid that Ainsley was too soft-hearted and would hesitate when she was about to massacre tons of ancestors.
Killing so many people would really be a burden to Ainsley, who came from a peaceful time, who also had the body and psychology of a child.
Sometimes, the body would affect Ainsley's soul and make Ainsley more childlike.
