Does a trade require equal standing?
That's clearly a lie.
Doro knows better than anyone that at this moment, within the sweet words of the Demon King Mohe, there is absolutely no genuine intent to be found; instead, it is he who is being seen through completely by her. She didn't say such words because she truly felt that way, but because she knew, he needed this.
What an "understanding" person.
If she weren't the Demon King but a true human, she might have become someone like a Wise King, or a noble Empress, for she could easily manipulate human thoughts within her grasp, observing and controlling at will.
Flower of Bewilderment.
Doro suddenly thought of this kind of flower. Back when he and Frodonick were in battle in the valley, Mohe used an alchemy item that looked almost identical to the Flower of Bewilderment to conceal herself.
