However, they had not come up empty-handed. The expressions on the faces of several security guards made it clear that they knew something had happened here. In other words, this matter was not entirely secretive. Aside from the few security guards, a considerable portion of the staff within the park likely knew about it too, and they could inquire further with others.
As for the target, Yang Xiao quickly found one. Not far from here, there was a public restroom, and next to it a small room visible through a window that served as a resting area, where an old lady wearing reading glasses was sitting cross-legged on a chair, knitting a sweater.
The old woman was dressed in white, wearing the uniform of the park's janitors, which Yang Xiao had seen on the way here; she even had a name badge on her chest.
