Duanmu Yan is a humble person who always answers other people's questions with gentle manners and likes to help weak cursed spirits return home at night...
"Does a cursed spirit deserve to die?"
Duanmu Yan: "Nonsense, if you don't die, am I the one who should?"
Why won't you let us go?
Duanmu Yan: "Let you go? Don't make me laugh. Even if you beg me, I won't let you go."
Louhu had fought him twice.
"So he's a top-tier mage? Looks like we can have some fun now."
"Are you kidding me? You want me to stop Duanmu Yan? Everyone knows he's a cursed spirit killing machine! His methods are extremely cruel!!"
