The footsteps never stopped, heading straight upstairs, so even though the second floor was turned upside down, no one would notice, and Gao Yang and the others could continue to hide in peace.
The sound gradually disappeared, and Gao Yang let out a light breath, whispering extremely quietly, "I don't know what they want, but I guess they are definitely not thieves."
Taylor whispered, "Should we go?"
Gao Yang thought for a moment and whispered, "Let's wait a little while. Leaving means opening the door, which will be quite loud. Let's wait a bit longer. Besides, we aren't really worried about anything, and their time here won't be long, plus..."
Gao Yang took out a small device from the bag, looking like a miniature walkie-talkie, and with a half-smile, said, "We can also listen to what they are saying."
Taylor chuckled softly and whispered, "A portable signal receiver for a bug, you've already installed it..."
