Just southeast of Qingce village lies this ruin of a bunch of destroyed buildings -- there is also a Domain of Frost Blessing at the top of the village. There are these blue flames everywhere -- so I've been wondering what's their purpose, and if anything, if they lead to any treasure of any sort.
The blue flames are just aesthetic in this particular area. You can't do anything with them.
These blue flames do not have any mechanical function. They are just ambiance.
They are a reference to Japanese folklore. Legend says, that souls of deceased people sometimes appear at night in form of Hitodama. Floating balls of fire in various unnatural colors.
