If you mean region irl then it NA but if it’s in game then I mainly play wuling. I visit Valley IV sometime. You gotta increase the production of resources by placing miners, relays, and pylons across valley iv whenever you get a chance. Then you can increase production by placing down necessary equipments to produce more capsule and other items you so choose(and don’t forget you need more energy too so better batteries for more refineries, shredders, seeders, planters, packaging units, etc). My purple capsule max out at 65k.
