There's no definitive conclusion about who the murder shadow is, but most players still believe it's Mr. Wen. The most pressing issue before them isn't this; as long as they kill the assassin, whether they succeed or fail in passing through, this instance will come to an end. Even if they can't leave for the time being, they can cooperate to avoid risks.
Of course, this is a problem for the dungeon players of the manor, but Xu Huo's group's issues are much more complicated.
Firstly, they don't know who the shadow is or how to maintain the hero's dignity. Even if they restrict players from passing through, the shadow is brutally murdering people, making it impossible to completely avoid bloodshed.
Secondly, if the shadow is indeed Mr. Wen, how does maintaining his dignity look? At this point, it's clearly not about stopping other players from assassinating him and protecting his identity; there's no need for that.
