Bai Yun was shocked that someone was able to sneak up behind him without him noticing, even in his distracted state. He turned around to see a young girl standing behind him with her hands on her hips and staring at him with a bright smile on her face.
"Nothing. I was just thinking about a hard problem." Bai Yun replied with a smile.
As he replied, he carefully studied the young girl. She seemed to be the same age as him, and was standing there wearing a golden dress, but without many other ornaments. And he also realised that the reason he couldn't sense her coming was because she didn't have any cultivation. Which was strange. This was the imperial palace. It seemed strange that a person without any cultivation could just walk in here. Especially considering how rich the clothes she was wearing looked.
"Who are you? I don't think I have seen you before?" The young girl asked.
