Returning to the ward where his father was staying, both his father on the sickbed and his mother on the makeshift caregiver's bed had already fallen asleep.
After checking on his parents, Xiang Kun quietly stepped out into the hallway again.
He attempted to co-manifest a piece of cake with a flick of his hand but did not succeed, so he looked up at the surveillance camera hanging in the corridor.
Before he "co-manifested", he knew the surveillance was there. With his various super sensory abilities, it was nearly impossible for him not to detect electronic devices like surveillance cameras; they were the type of thing he instinctively noticed, and paid special attention to, having developed it as an instinctive habit.
Xiang Kun was simply trying to "pretend not to know," fooling himself as he attempted to co-manifest.
