[Lan Wangji came prepared, albeit with some of this world's strange, distasteful tools rather than the cultivation tools he would have preferred. he'll pull a flashlight out of his sleeve and scan the walls of the tunnel as soon as he's gotten in far enough to see what there is to see down here. he'll closely examine the frame and the rivets, trying to think through the implications.

...

right. he's never seen a whole lot of urban construction infrastructure period, much less what's used in modern times. he has no clue what the fuck he's looking at.

thankfully, the holes and their placement do at least give him an inkling that there was more here at one point -- he's seen bolted doors before. he won't completely disgrace himself in today's Scooby Doo episode.]

Obstruction has been removed.
