XP farming. It's basically a rudimentary cash to donut converter so you'll need lots of cash to do this, additionally the higher your multiplier the faster you'll gain levels and also the less money you'll spend doing so. It consist of buying and selling decorations (since they don't have a building time) over and over. Once a decoration is placed you will get some amount of XP (generally 10% of the cost, except aspirationals that only give 1%). The Xp obtained makes you gain levels fast and thus get the level-up donuts earlier. Activating the XP Collider is a very efficient way to do the process since your XP multiplier will quintuplicate for the time is active. The Kwik-E-Marts although having a 4 hour building time, are currently the items that give the highest Xp per cash ratio if purchased in small groups.

Regarding the mountains part, they hacked it. There's currently no way to remove any part of the mountains between regular Springfield and Springfield Heights. The best you can do is move the Homerlayas and the Springfield Heights Tunnel in the mountain range, this last one requires both pieces of land acquired in both sides.
