New architectural idea

New architectural idea: Death Knight stronghold/elf house Corresponding to Halloween/Christmas activities, type: warehouse, capacity: 3,000, floor space: 2*2 grids, non-tradable, effect: production buildings in 6*6 grids are sent directly to the warehouse or materials are taken out from the warehouse without workers rushing. Evil necromancers will plunder the manufactured materials, although they don't need them either. Hard-working elves will pack the materials made in advance and send them to the places where they need them quickly.
