You can demolish buildings located outside the Base wall, including the Assembly Plant, Eco Farmland, Steel Furnace, Ore Refinery, Fuel Refinery, and Service Centers, by following these steps:

- Click on the building you want demolished, then select (Details).

- Click on the (Demolish) icon to speed up the demolition process using boost items or gold for instant demolition.

Please note that you must maintain buildings constructed during the tutorial or the service center added after completion. When demolishing a specific building, you must wait 24 hours before demolishing another, and this cooldown period cannot be accelerated.
