Who Is the 6th Person?

Ling Lan seemed to be looking around casually but in actual fact, she was gathering any useful information she could find.

She realized that the dining hall was filled with ordinary tourists. The dinner was a buffet where everyone just took what they wanted to eat. The food was ordinary too. There weren't any expensive ingredients and no chefs were present to cook food on the spot. The waiters took out trays of food from the back. They seemed delicious but might not be.

The tour group they joined was a civilian tour group. Ling Lan saw tourists, who dressed nicely in high-class clothes, walking in and out of the other two halls and knew that the other two halls served people with higher statuses.
