The companions transported to Yang Yu's side were all amateurs who didn't understand profound magic. Even if they knew the Count Blood had set up magic to prevent snooping, there wasn't any way to break it.
Fortunately, while there wasn't a person who understood magic, there was a spirit body that did.
Yang Yu took out a thin sheet of paper and opened it. A cyan mist wafted from the paper, transforming mid-air into a refined spirit steward.
Wang Wu Yidru's contracted spirit body, Nagasarro, bowed respectfully to Yang Yu, saying:
"Master Yang Yu, what is your command?"
Yang Yu originally intended to save Nagasarro as a trump card for the confrontation with Count Blood, but under the current circumstances, he could only have him act ahead of time:
"You once claimed that you are a somewhat famous magician. Can you sense the presence of magic beneath our feet?"
