Trespassers?

Right after Lin Ke had entered the room along with Lia and Prince Indra's crew, a strong, loud voice echoed through the halls.

"Hello everyone, thank you all for coming here." The voice shouts. "Now, I know all of you are impatient to head down to the Mystic Great Tree. However, before we call allow you all to go down there, we have to establish a few rules and check that everyone is accounted for."

Lin Ke tries to crane his neck and look through the crowd to find the source of the voice. However, he wasn't able to find the source. Helpless, he could only listen to the voice.
