anyone have a good lucky farming route?

i was thinking about farming for lucky points in low level areas with lock picks. however, i haven't found an optimal route yet. anyone have one, preferably with pictures?

Locked chests are random, so they randomly appear anywhere. But getting Lucky points through opening chests is by far the most expensive way to go, and least efficient.

If someone can provide jhu with a route, tell me and I'll reopen, but I don't think there is such a thing.
