Yao Shen keeps chancing looks at his mobile just to check the time.
Fifteen minutes have gone by and Jia Hao still isn't back.
Of course it's possible that he's doing as Yao Shen said, and trying to gather as much information as possible.
He told Jia Hao to return right away if he couldn't find the three people he described, so the fact that he's still gone is a good sign -- or so he tries to tell himself as the time for him to return to set approaches.
Yao Shen is sure of what he saw. That was the ghoul spying on him, and by now the Ghost Kings must have come to a decision regarding how to deal with him.
If they follow their previous steps, they'll want to wait until he's alone in his hotel room again.
Maybe if he finds out what they're planning he can stay one step ahead, and maybe prevent another premature death?
