World of the Main Storage: Main Storage Coordinates of the Main Storage: /tp 1242 138 1294

It has:

--- 3 large bulk storage areas to store almost 1278 items. --- 1 Parallel Unloader that unloads mixed shulkers that arrive and releases them at a rate of 5 items per shulker. --- Array Loader Filters for each item that is stored. --- An Item Sorter for non-stackable items that I think sorts 16 different types. --- An automatic blue shulker crafter for the entire warehouse that ensures all filters are always full along with the item sorter, crafting station, loose item input, displays, etc. --- Displays to store unique items that cannot be automatically sorted. --- The overflow for all extra items to store them, among the items that arrive there apart from those not in the filters are: beehives with bees inside, items renamed with an anvil, original banners, etc. --- A small corridor with all armor templates. --- A massive crafting station. --- A decorated room for the player to set their spawn point. --- Chunk loaders everywhere so the warehouse is always loaded when used even if the player is not manually loading the area. --- Inputs for full shulkers of the same item type that go directly to the bulk storage, input for mixed shulkers that go to the parallel unloader, an automatic trash can to burn items. --- A basic furnace for cooking. --- 2 anvil columns to repair or rename items. --- A chest that receives all the emptied shulkers from the warehouse. --- And the control panel from which you can see in real time everything that happens in the warehouse and only when all the lights are off is when the warehouse is totally
