Fit For an Exorcist

Chongyun, an expert exorcist with tons of successful exorcisms, yet has not yet seen a ghost or demon himself. That is, until, he meets a ghost named Xingqiu, who is unphased by his positive Yang energy. After making Chongyun convince not to exorcist him., Chongyun gives in and decides that he won't exorcist him. After all, this is the first time he'd seen a ghost for the first time: what if he doesn't get another opportunity like this? And so, they have a small talk and Chongyun leaves. However, perhaps letting that ghost off the hook was a bad idea?
