At this moment, Officer Wang walked in.
He was also taken aback by the tidiness of the room.
"Whoa, such clean walls, not like a teenager's room at all, no posters even," Officer Wang said unwittingly, causing Bai Yanliang to pause.
He approached the white wall and reached out to touch it.
"Officer Wang, we might need a UV light," Bai Yanliang said seriously.
Officer Wang turned to look at the wall, then at Bai Yanliang. Although he didn't quite grasp what Bai Yanliang was implying, he chose to trust him.
"Xiao Zheng! Get a UV light!"
While waiting for the officers to bring the UV light, Officer Wang also noticed Bo Wen's desk and the art-related books on it, and finally understood Bai Yanliang's meaning, feeling admiration for Bai Yanliang's speculation.
This young man's mind didn't seem to be swayed by external objects, nor affected by emotions. Maintaining such calm is exceedingly rare, after all, humans are ultimately not machines.
