Lan Wangji nods his head as he chatters instructions on how to use the elevator away, and by the looks of it, he gets it.

He nods also at how to use the keycard, remembering the room number of his room, and once he steps in to get comfortable and looking around his room, surprise it looks like his own jingshi.

Perhaps it's best not to tell Lan Wangji there's no reply back while he looks around his room. If there's no reply, that means his soul-twin is not physically here.

Turning around, he has to show his gratitude. "Thank you, Wei Ying."
