Yep, in fact there are multiple ways to do so.

I personally use Fire Spirit with Enchanted Locket and Bright Cookie as relay. For treasures I use three that give 25% bonus XP each. You can run in any of the first episodes for similar amount of XP. I prefer Ep3 since there is a higher chance to get a Warm Heart there.
