"You needn't worry about that; they're certainly still in this building," Ling Chen said.
Before the employees left, they all swiped their cards, and there were security department members assisting in the inspection; if any strangers appeared, they would have known.
"I couldn't find their whereabouts in the surveillance, I guess they're hiding somewhere."
"We need to find a way to force them out."
Ling Chen pondered for a moment before turning back to the security room, picking up the walkie-talkie, and connecting to the building's PA system.
"Now it's just you and me. Do you not even have the courage to face me?"
For a moment, Ling Chen's voice echoed throughout the entire building.
"I'll be waiting for you in the lobby on the first floor. I hope you won't make me wait too long." After speaking, Ling Chen put down the walkie-talkie and walked into the lobby.
