There was only one short sentence written on the clue card.
It seemed to be a clue related to the plot.
"Dear guests, please take note that each of the following missions will have a clear time limit. If you can't complete the mission within the specified time, you'll be punished accordingly."
The announcement sounded. It was clearly an emotionless mechanical voice, but it sounded much colder now. "The first mission. All the guests are required to return to the conference room on the fifth floor. The time limit is three minutes. The time starts now."
Bai Lin looked at the half-eaten orange with a pained expression and ran to the stairs.
The group quickly followed, but they were surprised to find that the door to the stairs was tightly locked.
