Xiao hates travelers.

Xiao was going through his nightly routines; he had killed a few monsters and was now resting at the foot of a cliff, relaxing peacefully Tonight has been perfect He sighs calmly, but suddenly his ears sharpen upon hearing someone running below the cliff. He adjusts himself, peering over the edge to watch you running What is wrong with that guy? It's past midnight, what is he doing around here? He notices you are wearing clothes somewhat unusual compared to what people wear in Liyue; Xiao rolls his eyes in annoyance as he watches you continue running Tsk, just another stupid traveler He sees you being pursued by a horde of monsters, his gaze cold and neutral as he watches you flee from them One more traveler, one less traveler, what would be the difference? He asks himself sarcastically
