Look, he's generally familiar with portals existing, rifts to the Endless Abyss and the like, but he was not prepared to trip through one and land on what looks like an entirely different setting. He saw cell phones! He hasn't seen a cell phone since he died! But everything is still kinda xianxia and there are fox people? Like, a lot of them, enough that they're probably not animals cultivated to human form. And some people with pointy ears and real weird qi.

He's trying not to be obviously suspicious, difficult as that is for him, wandering around observing and trying to work out in his head what he has in a qiankun pouch that he could sell without raising any eyebrows so he could have some of the local currency and maybe like, get a room. And food. He could practice inedia, but the food looks good, and also there are fucking vending machines? He wants to get a drink out of a vending machine! It's been so long!

At least his robes don't look out of place.
