As 'Lyra' heard the old man's words, the girl wasn't the slightest bit happy. Her expression remained impassive, if anything it could only be regarded as indifference or fake formality. Even though the girl didn't have to do so, being a demon for such a long time, she knew exactly how to manipulate the humans. They not only feared and revered the strongest but would also be driven if given enough credits.
In her eyes, the humans were easy to control. As long as you knew how to read them, you would be able to wrap them around your fingers and that was precisely what 'Lyra' was excellent at.
The girl knew when to exert her power and when to praise them, so they would feel flattered and more eager to work under her to gain that satisfaction of being acknowledged. After all, it was always good to be recognized by someone higher than you.
