Having talked to these people before, albeit unwillingly, Xie Lian will probably volunteer to go again if no one else can or is willing, or even if they are just for protection (their protection, not his). Although keep in mind that he forgot to pay his fine for public indecency last time he did that, which means there's a chance the city guards will start running after him if they spot him.

(He has shit luck so they absolutely will spot him.)
