Lie detector...
Is this really Ronald?
Faced with the current situation, any investigator with a cautious mindset definitely couldn't immediately believe Ronald's words.
But the person now is Nicole.
Her personality led to a turn of events.
Even though there was no difference in the alertness on her face compared to before, Nicole still attempted to recite the spell Ronald had just mentioned with a "might as well" attitude:
"Volume eleven, page two hundred sixty, item six."
"..."
Ronald himself was also a practitioner of the lie detector technique.
Although Nicole hid her magic fluctuations well while casting the spell, Ronald still sensed her actions.
So, without waiting for Nicole to ask, he proactively spoke as he detected the completion of her spell:
"Nicole, I am indeed the Ronald Adler you know."
"I'm here, without a doubt."
