After apologizing, she moved to answer Yang Qing's question.
"Yes, it's more than enough," she said with a smile. "Though, if you don't mind—it'll only take a couple of minutes—could you excuse me for a bit? I need to hand this over to Madame Cai Shan. For an item of this level she needs to be made aware of it as the supervisor," she added in an apologetic tone.
"No, it's no problem. I can wait," said Yang Qing with an easygoing smile. "I'll wait here," he added, already having decided where to sit: one of the futons beside a round table near a window, positioned to the front left of him.
Sun Biya nodded appreciatively and left as soon as Yang Qing settled into his seat.
Yang Qing smiled leisurely, glancing around with curiosity. The fourth floor was deceptively larger than it appeared from the outside, especially in terms of length, which seemed to stretch close to 300 meters across.
