@woodcutter The lines show that there are chests here, but they have been gone for a long time.

I don't understand what you mean, the tracers don't look like they are pointing to anywhere in the screenshot. Maybe a different angle would help.

@dyiing It's not about the perspective, I flew around this place from all sides. From all angles, he points to the invisible. Or rather, what is not.
