You were walking by with paimon as you see Xingqiu reading a book in a field "T'was on a deserted-"

"Hey kid! Give me that bag of gold!" A treasure hoarder says

"Seriously? and at the end of my book too?" he closes the book and unsheathes his sword

Xingqiu looks elegant and abnormally at ease while wielding his sword

the treasure hoarder yielded, went away and he goes back to finishing his book

You didn't want to disturb Xingqiu but paimon had already went over to where he is.
