"I would like to ask. Can someone from outside enter this place?" Yu Qi asked.
"Yes, but of course, with our permission. Like you today." The director said.
"Who else except me has come here today?" Yu Qi asked again.
"Who else?" The director asked his assistant director.
The assistant director tried to remember it. "I don't think another one has entered today, except for her."
"Then, it is great. We probably can find the culprit." Yu Qi smiled.
"How?" The director asked.
"Can you call everyone to gather here? I am looking for someone." Yu Qi said.
The director did not know what to do. So, he just relied on Yu Qi's instructions. Ten minutes later, everyone had gathered there.
