Earlier, inside the office building...
Yu Shiran cautiously walked through the empty corridor, then warily pushed open the doors on either side to look inside. After checking several offices in a row, the staircase leading to the upper floors appeared in front of her.
"Nothing on the first floor..." Yu Shiran raised her left hand to her ear and muttered as if talking to herself, "Do you need me to go to the second floor?"
"No, you'd better wait for us together," Black Silk replied.
"Hmm? Why? I can search this place by myself," Yu Shiran asked in confusion.
"I always feel it's going too smoothly… Besides, in case something unexpected happens upstairs, you would sell us all out," Black Silk said.
"Ha..." Yu Shiran thought for a moment, then shrugged, "Alright, I'll wait here."
