Yun Xi hadn't expected Bai Zhi to come looking for her Energy Stone. When she took it, Bai Zhi had clearly been unconscious; it was impossible for her to know that Yun Xi was the one who had taken it.
Otherwise, after all these years, Bai Zhi wouldn't have waited until now to come asking for the Energy Stone.
'She must have heard something from someone, which is why she's so impatient to test me.'
At this thought, Yun Xi composed herself and asked with a puzzled look, "Your Energy Stone? What Energy Stone? I don't have your Energy Stone here."
Bai Zhi had expected she wouldn't admit it and exposed her directly. "Stop pretending. Back then, while I was unconscious, you took the Energy Stone from my hand—the one my father traded his life for in the Endless Sea Area to cure my illness. And you claimed you found it by accident! Energy Stones are exceptionally rare. I lost an Energy Stone, and by sheer coincidence, you just happened to get one around the same time?"
