An Zhifeng was anxious. He searched every bathroom stall and found Xiao Hei's phone had fallen into the toilet in the stall by the window, and that window was open.
The bathroom couldn't possibly have surveillance cameras, and it was a private place with people coming and going, so it was unlikely they'd gather any useful information. An Zhifeng carefully recalled the people who went in and out earlier, but there were so many that no suspicious ones came to mind.
"How long from when Xiao Hei entered the bathroom to when you went in?" An Yiqing asked coldly at the door of the men's restroom.
"Less than fifteen minutes!"
An Yiqing pushed open the door of the bathroom and walked in without a word. Many men who were in the middle of relieving themselves were startled and turned away. A few curious ones shook their heads as they looked at An Yiqing, but were stared back by An Zhifeng.
