"Now then, how do you want to die?"
Hearing Nathan's arrogant words, the killer's eyes that had been observing him the whole time turned colder.
Although he is a little angered, the killer still did not dare to make any sudden moves.
He was wary of Nathan especially since he felt the strength contained within that tiny pebble that hit him.
It was enough for him, who has been strengthened by the demon multiple times, to feel pain!
That is why he knows Nathan is not just an ordinary human he can treat as a prey like the people he killed before.
Squinting his eyes, with a wary tone, he asked, "Who are you?"
With suspicion, he said, "Are you also… a Demon Servant?"
Hearing the new term, Nathan suddenly raised an eyebrow.
'Demon Servant? It's the first time I'm hearing of it but there's no doubt that this is related to those nasty demons.'
He did not answer the question of the serial killer.
Instead, he used the appraisal on him to learn more about this serial killer.
