"Fine, we do have a certain rapport with those Death Knights; we can inquire further."
The other party nodded, then bid farewell and left.
They also knew that the Undead were not like Elemental Beings, merely acting on instinct. On the contrary, some of the Undead possessed high intelligence, thus capable of communication.
In fact, this was better; they did not have to use overwhelming strength to suppress them and force them into contracts like others did.
As long as they could get their consent, even if there was a significant difference in strength, they could still make a contract.
The strength of those Undead Creatures was no small matter; they usually gathered in large groups. If one were to forcibly confront them, even the Elemental Holy City would probably be reluctant to do so, due to the tremendous losses that would be incurred.
As for their ancestors, those were top-tier beings not to be trifled with.
